ICE-HARVESTING MACHINE} SPECIFICATION forming part of Letters Patent No. 723,774, dated March 24, 1903.

Application filed May 17,1902. Serial No. 107,824- (No model.)

To all whom it ymty concern:

Be it known that 1, JAMES B. HAUSE, a citizen of the United States, residing at Clinton, in the county of Lenawee and State of Michigan, have invented new and useful Improvements in Ice-Harvesting Machines, of which the following is a specification. g

This invention relates mice-harvesting machines; and the object of the invention is to provide an improved machine of this character capable of cutting the ice simultaneously in transverse direction-that is to say, into blocks.

The improved machine includes a main cutter and an auxiliary cutter, the main cutter being adapted tocut the ice longitudinally of the machine, so as to form strips, while the auxiliary cutter cuts through these strips to form the blocks, which may be suitably disposed of. The frames for both cutters are mounted for oscillation, that of the main cutter being adjusted byhand, while the one for the auxiliary cutter is lowered and raised automatically during the advance ofthe machine, such frame of theauxiliary cutter being so mounted that it has a movement relatively to the frame of the machine, whereby when the auxiliary cutter is in the ice the machine can advance without necessitating the stoppage of either of the cutters, which consist, preferably,of rotary saws, the same being continuously operated during the action of the machine. Simple and efficient mechanism is provided for operating the two cutters or saws'in unison and for raising and lowering the frame of the auxiliary saw at proper times and for also propelling the machine either forward or backward -or for quickly stopping said machine.

The invention includes other objects and advantages which with the foregoing will be set forth at length in the following description, while the novelty thereof will form the basis of the claims succeeding such description, and such invention is clearly represented in the accompanying drawings, forming a part of the specification, and in which- Figure l is a top plan view of an ice-harvesting machine including my invention.

Like characters refer to like parts in all the figures of the drawings. Y

The improved machine carries mechanism for propelling the same along the ice and working automatically will out the ice into separate blocks of uniform size ready for storage without the use of any other saw, ax, or spud and without the aid of any operator, with the exception of one at the end of the ice-field, who will be required to stop the machine and set it over sidewise the width of one cake and reverse the propelling mechanism, as will hereinafter appear at length.

The machine includes inits construction a frame of some suitable construction, the one represented being denoted in a general way by 15 and having on its uppers-ide the deck or platform 16, which is adapted to sustain a motor of some suitable kind for propelling the machine and foroprating thecutters and which deck or platform has a narrow extension 17, upon which the operator can stand, so as to be within reach of the various governing-levers.

The frame 15 has on the under side thereof, crosswise of the same, the axles 18 and 19, the axle 18 being at what I shall for convenience term the front of the machine, for, as will hereinafter appear, said machine is adapted to travel oppositely upon the ice without turning.

The axles carry at their ends tractionwheels 20, peripherally roughened, so as to secure the proper action of the same.

The invention is of course not limited to the construction thus far described and hereinafter set forth and as illustrated fully in the accompanying drawings, for many variations may be adopted within the scope of my appended claims.

I will now describe a mechanism which is adapted for propelling the machine along the ice and for securing reversals in direction of movement thereof or complete stoppage of the same.

The motor is mounted on the platform 16. I have not deemed it necessary to represent the same, for it may be of any suitable type.

The numeral 21 indicates the main shaft, or it may be the motor-shaft, from which the propelling mechanism derives its motion, and, as will be hereinafter pointed out, the sawactuating mechanism is also operated from such shaft.

Standards or uprights 22 rise from the frame of the machine and carry in suitable bearings the cross-shaft 23, provided at its inner end with a sprocket-wheel 24, Figs. 1 and 6, connected by a sprocket chain 25 with the sprocket-wheel 26 on the said main shaft 21. To this cross-shaft is feathered for sliding movement a friction-roll 27, to which is suitably non-rotatably connected the bail or yoke 28, the hand-lever 29 being pivotally connected with said bail, such lever being snitably fulcrumed to the framingand its handle being within easy reach of an operatoron the platform extension 17. The friction-roll is adapted to engage the working face of the friction-disk 30, carried at the upper end of the vertical spindle 31, it being understood that the horizontally-disposed friction-roll is adopted to rotate the disk.

The spindle 31 has fast on its lower end the bevel-gear 32, meshing with a corresponding bevel-gear 33, Figs. 4E and 5, loose on the forward axle 18, the bevel-gear 33 having an integral pinion 3 L, meshing with a fixed and larger pinion 37 on a counter-shaft 37, also carrying a small fixed pinion 37", meshing wilh a larger and fixed pinion 33" on the said front axle 18, said axle being connected by sprocket-gearing (denoted in a general way by 38) with therear axle, so that such axles can be thereby driven in synchronism.

When the friction-roll 27 is in the position illustrated in Fig. 5, the machine will be driven forward at a relatively high speed, and by moving the roll nearer the axis of the disk the velocity of the. machine will be reduced, and the same can be stopped by mov ing the roll to the dead-center of the disk, while its motion can be reversed by putting the roll across such dead-center.

The train of gearing hereinbefore described constitutes a simple means for properly regulating the speed of the machine along the ice.

While the movement of the machine can be arrested by the roll 27, which can be moved sidewise along its supporting-shaft 23 by the hand-lever to the dead-center of the disk 30, still I provide other means for this purpose, the roll being shifted out of contact with its disk for this purpose, as will now be set forth.

The shaft 23 is sustained by bearings 39, suitably mounted for vertical sliding movement against the inner faces of the standards 22. Links 40 are pivoted to said slidable bearings and are likewise eccentrically connected to the ends of the shaft ll, also sup ported by said standards and situated above the other shaft. The said upper shaft is provided with a hand-lever 42, Figs. 4 and 5. By swinging the hand-lever rearward the friction-roll 27 through the intermediate connections is lifted off the upper face of the disk, so as to stop the machine, provided the machine be moving. When the friction-roll is free of its disk, the former can be moved along its shaft 23, so as to change the direction of movement of the machine, if necessary.

When the machine is traversing the ice, the friction roll or wheel is in contact with its disk; and to assure the proper engagement of the same the hand-lever 42 is weighted, so as to hold the roll firmly against its disk. By swinging the lever rearward the roll is lifted clear of the disk and is then moved a sufficient distance until its center of gravity has crossed a vertical line intersecting its center of motion, at which point it is adapted to abut against a suitable stop, as 43, on the framework, Fig. 3, such stop consisting in the present case of a nut carried on one end of a shaft hereinafter more particularly described.

As will hereinafter appear, the machine includes main and auxiliary saws, and before they are put into action I mark a line across the ice and will now describe a suitable marking device for obtaining this result.

Viewing the machine from what I have termed the front, it is provided at its left with a peripherally serrated and toothed marking-wheel 44;, fixed to the short shaft or mandrel 45, connected by pulleys and belts with a power-shaft, hereinafter described, so that when the machine is driven along the ice and such shaft is rotated the said marking-wheel will make a cut in parallelism with the direction of movement of the machine and which cut is made as straight as it is possible for the operator to make it. After the marking cut or groove has been made, and such cut or groove is a comparatively shallow one, guide-wheels 46 are let into said out during. the return trip of the machine, and on such return trip the saws for forming the ice into blocks are put into action.

The guide-wheels are in alinement with each other longitudinally of the machine and are separated transversely of the machine a distance agreeing with the width of the strips of ice cut by the main saw. Said guidewheels are carried by the swinging brackets 47 at the ends of the frame 15, and links 48 are connected with the respective brackets and also with hand-levers 49, pivoted at their lower ends in proximity to each other to the side bars of the frame 15, (see Fig. 7,) and notched plates, as 50, are adapted to cooperate with the respective levers to hold them in their two positions.

With the parts in the positions shown in Fig. 7 the guide-wheel 46 is adapted to enter the groove previously made in the ice by the rotary 1narking-Wheel44. At the end of the movement of the machine in one or the other direction the machine is shifted laterally; but

' before this can be done it is necessary to lift the guide-wheels out of the marked or guide groove. This action can be accomplished by swinging the hand-levers 49 outward, and when the machine has been moved the req uisite distance sidewise the two guide-wheels 46 will be lowered. into the guide-groove just formed by the machine and the latter will be moved in a direction opposite that last followed.

It will be seen that the plates 50 are provided with two notches, Figs. 1 and 7, to hold the two levers 49 in their two positions, respectively. The first thing that takes place, therefore, on the initial movement of the machine is the formation of a guide-groove by the marking-whecl 44, and on the return of the machine the guide-wheels 46 will be lowered into said groove, so that as the machine is propelled such guide-wheels prevent lateral motion of said machine and hold it to a straight course.

I will now describe the means shown for shifting the machine sidewise after the conclusion of a course thereof. Pivot-bolts, as 51, extend vertically through the end bars of the frame,substantially midway of thelengths thereof, and outwardly-extending levers 52 are pivoted to the upper ends of such bolts and are fulcrumed at the middles to posts or columns 53, which terminate attheir lower ends in feet or bases 54, adapted to slide along the ice and suitably braced. (See Fig. 8.) By lowering the outer or free ends of the levers 52 the frame 15 can be lifted, and by moving the same horizontally the said frame can be carried to the left or until the guide-wheels 46 are above the previously made guidegroove, at which point the said wheels will be lowered into said groove and the machine propelled to follow a course opposite to that last taken, and during such period of operation the marking-wheel 44 will make a second groove. Subsequently the main or longitudinal saw will be let into the marked groove, which causes the making of a straight cut through the ice.

perfectly My improved machine includes a plurality of sawsa main saw and an auxiliary saw the same being capable of simultaneous operation and the main saw cutting the, ice longitudinally of the same, while the auxiliary one cuts the ice crosswiseof the main one, so that such ice is out up into blocks, and in the present case each saw is continuously rotated, as will hereinafter appear, and I will .now describe the main-saw mechanism and its operation. suitably fixed to a shaft 56, rotatably mounted at the outer end of a rocking frame 57,which is sustained for oscillation by the shaft 58, connected by belt-and-pulley mechanism with the saw-shaft. saw, as will hereinafter appea'r, is also driven by power-transmitting mechanism operable by said shaft 58. Said shaft 58 is provided with a sprocket wheel 59, connected by sprocket-chain 60 with the sprocket-wheel 61 on the motor-shaft 21. .Theshaft 58 is stopped and started through the agency of a clutch 62, the one shown being of the friction type and its movable member being operated by the hand-lever 63, the handle of which is within convenientreach of the operator. In Fig. 3 the movable clutch member is shown as being out of contact with itscompanion, so that both saws are held at rest duringthis relation; but when put into contact therewith the two saws willbe rotated, so as to cut the ice. It will be understood that the movable clutch member is splined to its shaft, while its mate is loose thereon, butis rigid with the sprocketwheel 59, the prime pulley 64 of the main-sawrotating mechanism being also fixed to said shaft. A rock-shaft 65 is supported by the standards 22, Figs. 1, 2, and 3, and is provided at its outer end with a crank-arm, provided in turn at its outer end with a link 67, jointed to the rocking main-saw frame 57. A lever 68 is fastened to the rock-shaft 65, and it carriesa detent 69, cooperative with the fixed toothed sector 70, the detent by engaging the teeth of the sector'serving to hold the lever, and thereby the main-saw frame, in an adjusted position. The said lever 68, which, like the other levers, is within easy reach of the operator, carries means for operating the detent 69 thereon, and such lever when manipulated serves, through the intermediate mechanism, for raising and lowering the main-saw frame The main sawis denoted by 55, and it is The auxiliary or crosscutting i .IOO

57, to thereby move the main saw out of and into the operative position."

The marking-wheel 45 has its shaft sup-.

.ing apparent that such last-mentioned frame is elevated when the machine is being shifted sidewise and is then lowered when the machine has been 'moved the desired lateral distance.

The auxiliary cutter or saw is denoted by 73, and its shaft 74: is supported for rotation at the outer end of the frame 75, carried for oscillation by the shaft 76 on the upper side of the machine, and said frame has a sliding movement along said shaft, as will hereinafter appear. The auxiliary-saw frame 71 carries a shaft 77, provided at its ends with bevelgears 78, the outer one of which meshes with a similar gear 79 on said auxiliary shaft,while the inner one of which meshes with a like gear 80 on the longitudinal shaft 76, such gear 80 having a key (not shown) fitted into the groove or channel 81, extending lengthwise of said longitudinal shaft 76. By reason of this construction the auxiliary saw can be continuously rotated while the auxiliary-saw frame is being moved back and forth on the machine, the bevel-gear 80 having a sliding movement with such frame. The longitudinal shaft 76 is provided at its forward end with a bevel-gear 81, meshing with a similar bevel-gear 82 on the counter-shaft 58, so that on the rotation of the latter the auxiliary saw will, through the intermediate connections just described, be rotated.

The mechanism for raising and lowering the auxiliary or crosscutting saw frame 75 is automatic and is operated from one of the axles, orthe propelling mechanism for such operation need only take place during the propulsion of the machine.

The longitudinal shaft 76 loosely carries the rocking levers 83, the arms of which extend angularly from said shaft, such anglelevers being separated a suit-able distance and their outer ends being rigidly connected by the cross-bar 8 1, Figs. 1, 12, and 13, said cross-bar constituting a track for supporting for traveling movement the slidable and oscillatory auxiliary-saw frame 75 and the latter being provided with antifriction-rolls 85, bearing at suitable points against the upper and lower sides of the cross-bar or track 84, Fig. 13.

The inner arms of the angle-levers 83 are jointed to the links 86, depending therefrom, and likewise united to crank-pins 87 on the crank-disks 88 on the shaft 89 in parallelism with the longitudinal shaft 76. The parts are so arranged that on each rotation of the crank-disks the auxiliary-saw frame is given a complete oscillation, so as to cut the longitudinal strips of ice into blocks.

The shaft 89 has a fixed pinion 90, adapted to cooperate with a mutilated gear 91, the ratio between the gears 90 and 91 being a oneto-two one, so that when the mutilated gear makes a half-rotation the pinion will make a complete rotation. The mutilated gear 91 is carried by a shaft 92, and its teeth are omitted on half the periphery thereof, so that when the plain portion thereof is contiguous to the pinion the auxiliary-saw frame will not be oscillated, whereby such frame can be moved sidewise without affecting the proper action of the parts. The mutilated-gear shaft is provided at its forward end with a bevelgear 93, meshing with a cooperating gear fixed on the cross-shaft 94, the latter being connected by a train of gears 95 with the forward axle 18 and the first gear 95' of said train being loose on the shaft 94. The gear 95 is normally coupled to its shaft by the clutch 94., by operating the shipping-lever 96 of which the automatic operation of the auxiliary-saw frame can be stopped. 1

It will be understood that as the machine is propelled along the ice the auxiliary-saw frame 75 is oscillated to first cause the auxiliary saw to enter and then to leave the ice. As the auxiliary saw is let into the ice-the machine will be traveling forward, and by reason of the fact that the auxiliary-saw frame is slidable longitudinally of the machine the latter can be moved forward while the auxiliary saw is making its cut, and when such cutting operation is concluded the said auxiliary-saw frame will be moved forward to its initial position, as shown, for example, in Fig. 2.

I provide mechanism for sliding the auxiliary-saw frame along the machine of such a character that it is ineflicient as a powertransferring factor while the auxiliary saw is cutting the ice, but which is adapted to shift such frame relatively to the frame of a machine after a out has been made, and such mechanism will now be described.

The shaft 94, which it will be remembered is driven from the forward axle 18, carries a fixed gear 96, Fig. 1, meshing with a fixed pinion 97 on the shaft 98. The shaft 98 carries a pair of sprocket-wheels 99, arranged in parallelism on the said shaft and adapted to respectively receive sprocket-chains 100, which also pass around the sprocket-wheels 101, fixed to the short shaft 102, the parts being so arranged that the upper runs of the parallel chains will be operated in a direction opposite to that followed by the machine. For example, when the machine is traveling forward, as shown by the arrow in Fig. 1, the upper runs of such chains or belts will be moved to the direction of the arrow in Fig. 10. The connections between the chains and forward or driving axle 18 are such that the speed of the chains equals that of the machine. A pin 102* extends through alined links of the chains and is suitably secured thereto, so as to follow a circuit while the machine is making a forward and backward course on the ice. By employing two chains the pin is held against lateral motion during the operation of the machine. A link 103 is pivoted to the pin 102 and is likewise connected with the connecting-rod 104, guided in a horizontal direction and having at its rear end a bifurcated portion 105, adapted to straddle one of the sides of the auxiliary-saw frame 75, the branches of the bifurcation carrying antifriction-rolls 106,serving their usual function.

It will be remembered that the surface speed of the endless chains 100 isthe same as that of the machine and that the upper runs of the said chains travel in a direction opposite that of said machine, so that while the machine is advancing a given point on the upper horizontal run of the chain will be perpendicular to a fixed point on the ice. YVhen, however, such given point on the chain passes to the lower run, it will move in the direction of movement of the'machine and at a speed twice that of the machine relative to such fixed point, so that the auxiliary-sawframe, which is controlled by the said chains, will when the auxiliary saw has been taken from the ice after a cross-cut be returned to its initial position at relatively an accelerated velocity.

In Figs. 10 and 11 the endless chains 100 are shown as occupying their primary positions, while the same relation follows with respect to the auxiliary saw frame 75 in Fig. 2.

With the machine moving forward in the direction shown by the arrow in Fig. 1 the upper runs of the chains 100, throughthe hereinbefore-described connections, will be carried rearward, and while the pin 102 is moving along the upper runs of the said chains it remains in perpendicular alinement with a fixed point on theice, and while the link 103, rod 104:, and auxiliary frame 75 are moving relatively to the frame 15 of the machine they have no movement longitudinally of the machine relatively to the ice, and it is during this period that the auxiliary-saw frame 75 is oscillatedto carry the auxiliary saw 73 into and from the ice, as previously described, to make a cross-out, it being understood that the saw is being continuously rotated. At about the time the auxiliary saw leaves the ice the pin 102 will have reached the lower horizontal run of chains 100, so that such pin will be carried forward ata speed twice that of the machine relatively to a fixed point on the ice, the connecting-rod 104:, through the agency of the intermediate link 103, being thrust forward at the same relatively increased speed and. serving to rapidly return the auxiliary-saw frame to its primary position. The same operation of the chainswill of course take place when the machine is being propelled rearward.

The parts are so timed thatat the point the plain or non-toothed portion'of the mutilated gear 91 is opposite the pinion 90 the auxiliary-saw frame 75 is being given its accelerated forward motion, and thereby the said frame is prevented from oscillating, and at the proper moment, or when such auxiliarysaw frame is in its primary position, the teeth of such mutilated gear will meshwith the pinion to oscillate said auxiliary-saw frame. The parts are so related that the mutilated gear 91 will be in position to mesh with the teeth of the pinion 90 at the proper time, so as to secure the desired intermittent action of the oscillatorysaw-frame.

A bail 107 has its branches pivoted to suitable uprights on the frame, and such branches have depending rods at their outer ends secured at their lower extremities to the cross-bar on track 84. Said bail carries at its inner end a counterweight 108, adapted to rest against rubber or like buffers 109 on the block 110. When the auxiliary-saw frame 75 is lowered, as previously set forth, the said weight will be lifted and will be lowered into contact with the said buffers on the elevation of said auxiliary-saw frame. The purpose of said weight 108 is to counterbalance the frame carrying the same, so that the power necessary to operate such frame is reduced to a minimum.

The auxiliary saw 73 does not, as hereinbefore described,-separate the blocks from each other, this operation being secured by a wedge operative with said auxiliary saw and which I will now describe. The shaft 74; of said auxiliary saw, Figs. 1, 2, and 3, has a disk 111, concentric with the auxiliary saw and adapted to fit flatwise against said saw and having beveled portion 112. The disk is adapted to enter the cross-cut with the auxiliary saw, and when the latter has entered a desired distance into the ice'the beveled face of the Wedge-disk is adapted to forcibly.separate the blocks from each other when the ice is in the form of strips. In some cases this wedge-disk 111 could be dispensed with and the auxiliary saw after it left the'cross-cut would leave the block connected with the body of the ice by narrow necks at the inner corners thereof. These necks could readily be broken at a subsequent and independent operation. To prevent rebounding of the weighted lever or bail 107, I connect the outer end of the same with a coiled spring 113, the

same being also connected with the frame of the machine.

It is believed that the complete operation of the machine will beat once apparent from the foregoing description. Briefly set forth, it is as follows: The machine will be run forward and then backward over the ice, it being shifted sidewise after each course, as previously stated, and when several guide 'or marking cuts have been made by the markcourse will be lowered manually into the last out, and when the machine is propelled forward the said saw will cut the ice longitudinally of the machine or in the direction of travel thereof. During this period the auxiliary-saw frame 75 is being automatically rocked, as hereinbefore set forth, to carry the auxiliary saw 73 into and from the ice, it being understood that the saws are being both continuously rotated. When the auxiliarysaw frame is lowered, the machine is moving forward, leaving the auxiliary-saw frame stationaryrelativelytotheice. Vvhemhowever, the said auxiliary-saw frame is elevated, it is slid forward on the machine to repeat the operation.

The complete operation just briefly outing-wheel 44: the main saw 55 on the nextlined will be repeated while the machine is being moved forward and backward.

In an ice-harvesting machine, the combination of a shaft, a cutter-carrying frame arranged to oscillate upon said shaft, a trackcarryiug frame also oscillatory on said shaft and along the track of-which said cutter-carrying frame is adapted to travel, means for positively operating the track-carrying frame, a driving member feathered to and slidable upon said shaft, a driven member supported by the cutter-carrying frame, a cutter rotative upon the latter, connections between thedriven member and the cutter for actuating the latter, means for driving said shaft, and mechanism for causing the cutter-carrying frame to reciprocate upon said track and for maintaining the same in a fixed position relatively to the ice for a given time.

14. In an ice-harvesting machine, an oscillatory cutter-carrying frame, an oscillatory track-carryin g frame along the track of which the cutter-carrying frame is adapted to travel, means for lowering the track-carrying frame and for maintaining it in its lowermost position for a predetermined length of time and for then elevating the same, and mechanism for causing the cutter-carrying frame to reciprocate upon said track and for maintaining the same in a fixed position relatively to the ice for a given time and while the trackcarrying frame is in its lowermost position.

15. In an ice-harvesting machine, an oscillatory cutter-carrying frame, an oscillatory track-carryingframealong the track of which said cutter -carrying frame is adapted to travel, means for positively operating the track-carrying frame, including a pair of meshing gears, one of which is mutilated, and mechanism for causing the cutter-carrying frame to reciprocate upon said track and for maintaining the same in a fixed position relatively to the ice for'a given time.

16. In an ice-harvesting machine, a main cutter arranged to cut ice in the direction of the traveling machine, an auxiliary cutter,an oscillatory frame-for carrying said auxiliarycutter, an oscillatory track-carrying frame along the track of which the first-mentioned frame is adapted to travel, mechanism for positively operating said track carrying frame, an endless belt, connections between the belt and the said auxiliary-cutter-carrying frame for reciprocating the latter and for also maintaining it in a fixed position relatively to the ice for a given time, means for driving the belt at the same speed as the machine, and means for driving the two outters in unison.

17. In an ice-harvesting machine, a cutter arranged to cut the ice in the direction of travel of the machine, a second cutter arranged to cut the ice crosswise of the other cutter, means for lowering the second cutter toward and into the ice and then'elevating the same, an endless belt, means for operating the belt at the same speed at which the machine is driven along the ice, and connections between said belt and second cutter for maintaining the latter in a fixed position relatively to the line of travel of the machine while said second cutter is in the ice, and for subsequently moving said second cutter in the direction of the length of the travel of the machine. 7 r
