S AWING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 477,972, dated June 28, 1892.
Application filed May 7 189 1.
To all whom it may concern.-
Be it known that I, FREEMAN M. TEEGUARQ DEN, ofColfax, in the county of Clinton and State of Indiana, have invented certain new and useful Improvements in Sawing Machines {and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters and figures of reference marked thereon, which form part of this specification.
This invention relates to certain improvements in sawing-machines.
The object of the invention is to provide an improved sawing-machine having an automatic feedingdevice capable of feedingplanks or logs of various thicknesses and dimensions to the saw.
A further object is to provide afeedingdevice capable of receiving and feeding planks, logs, or timber of different dimensions, and which is automatically varied in speed according to thickness of material operated upon; and a further object is to provide cer-v tain improvements in constructions and details, whereby a greatly improved and highly efficient machine is produced.
These objects are accomplished by and my invention consists in certain novel features of construction and in combinations of parts more fully described hereinafter, and particularly pointed out in the claims.
Referring to the accompanying drawings, Figure 1 is a perspective of the machine, portions being broken away. Fig. 2 is an elevation from opposite side to that of Fig. 1, parts being broken away. Fig. 3 is a top plan. Fig. 4 is a horizontal section taken in a plane just above lower horizontal sills of main and movable feed-frame. Fig. 5 is a detail view of feed-saw and its supporting and adjusting means. Fig. 6 is a detail view illustrating the connecting and controlling mechanism between the movable feed-frame and the beltshifter.
Referring to the accompanying drawings, a indicates the main frame of the machine, comprising suitable vertical posts, end sills Serial No. 391,896. (No model.)
and horizontal bottom side sills bl), and upper horizontal sills 1 2 3.
c is the saw platform or table. d is a ripsaw extending up therethrough and mounted on horizontal mandrel e in suitable boxes and provided with drive-pulley) and on outer end with small drive-pulley g. The outer portion of the table, both in front and in rear of the saw, is removable from under horizontal supporting-beams 4L 5 6 7, extend-- ing laterally from the main frame so that the saw can be removed from its mandrel. Two clampingrbars t' 2' are beneath this movable portion of table and pivoted thereto between their ends by vertical bolts 8, so that the clamping-bars 2' 2' can swing beneath and engage lower edges of beams l 5 6 7and thereby lock the table down in position. To release the tabie, one end of each clamping-bar should be swung in and the other end out, thereby freeing the bars fromsaid transverse supporting beams; A vertically-movable swinging frame is pivoted within the main frame and consists of the lower rectangular frame 10, composed-of end and side sills located within the lower portion of the main frame, so that its front end can swing vertirally. A vertical frame is carried by said lower movable frame and consists of two uprights 9 9, secured to end sills of said movable frame and extending up substantially at right angles thereto and at their upper ends a suitable distance above said main frame connected by upper horizontal beams or frame 50, the frame 10 and upright frame 9 and beams 50, carried thereby, swinging together vertically as one frame. This swinging feed-frame at the lower portion of one end is mounted in suitable-bearings to allow vertical swing of the front portion thereof by means of tubes or pipes 11, rigidly secured at their inner ends upon the lower side sills 10.
frame. Alarge pulley 13 is mounted on the outer end of said shaft, and the driving-belt 14 connects said pulley 13 with pulley g on the rip-saw mandrel. Between the lower side sills of the swinging frame the shaft 12 is provided with a cone-pulley 14. Another shaft 15 is journaled in the forward part of the swinging frame only and is provided with the cone-pulley 16, oppositely arranged to cone-pulley 14, the shafts 12 and 15 being parallel and belt 17 connecting said two pulleys. Shaft 15 is provided with a small sprocket-wheel 18at its outer end, connected by drive-chain 19 with large sprocket-wheel 20, carried by counter-shaft 21, journaled on a movable frame and provided with small sprocket-wheel 22, connected by sprocketchain 23 with sprocket-wheel 2 L on the end of the mandrel 25 of the feed saw or wheel. This mandrel 25 is horizontally carried by the top beams 50 of the swinging frame, so as to extend horizontally from the working table and carry the feed saw or. wheel 26 in advance of the rip-saw. This feed-saw. mandrel is journaled in an elongated box 27, adjustably clamped to the under sides of horizontal beams 50 by means of bolts 28, rigid with said box and extending up to the clamping-block29 upon the upper edges of said beams 50 and through which said bolts pass and are provided with nuts upon the upper. side of said clamping-block;
(See Fig. 5.) By this means the box carrying the feed-saw mandrel can be rigidly and adjustably clamped to the movable frame and can be adjusted so that the feed-saw will move toward and from the rip-saw by loosening the nuts of said clamping-bolts and then moving the box 27 and clamping-block lon: gitudinally of said beams 50, so that the feedsaw can be adjusted to. any desired distance from the rip-saw. Hence when rip-saws of different diameters are used in the same machine the feed-saw; can be always kept the desired distance from the rip-saw. Braces 30 are secured to block 29 and to the box 27.
The hub of the feed-wheel is provided with annular groove 31, into which the arms of forked piece 32 loosely fit to allow free rotation of said hub, so that the hub can be moved longitudinally with said forked piece. The horizontal lever 32' is pivoted to the outer end of the forked piece and fulcrumed at 31' to the feed-saw mandrel-box, the handle of the lever preferably extending toward the front end of the machine. By means of this lever and by having the feed-saw movable longitudinally on the mandrel or having the mandrel and feed-wheel moving longitudinal together the feed-wheel can be shifted transversely of the saw-table for various purposes. For instance, the operator when wishing to square an inch piece from a piece an inch by an inch and one-eighth moves the feed-saw to the center of the piece and then moves a suitable gage to one inch, then feeding the piecethrough, sawing off one-eighth-inch edge,
. the proper amountof pressure.
leaving feed-saw in the center of the inch piece and holding it and feeding it forward, preventing variations.
A suitable gage is provided-such as movable bar 33-ou the saw-table, having rearwardly-extending rack-bars meshing with gearing on shaft 34, which is provided with suitable hand-wheel, suitable clamps being also provided to'hold the gage in proper position. The present invention, however, has no bearing on this gage.-
The front end of the movable feed-frame is counterbalanced by means of eccentricallymounted vertical wheel or pulley 35, journaled at 35 in the front-lower portion of the main frame and provided with a strong flexible connection 36, secured at one end to the periphery of said wheel, so as to lie on its periphery, and at its opposite end secured to the lower side of the movable front end of said eccentric wheel. The radial arm 37 is rigid with and extends outwardly from the wheel35 and is weighted at its outer end by weights-such as 3Swhich constantly tend to rotate the eccentric wheel, so as to raise the movable frame, the'weights being of such size and so arranged, that the movable frame is counterbalanced, so as to easily .rise and fall and cause the f eed-wheel to en gage wood operated upon with By reason of this construction the feed-wheel is rotatedfrom the saw-mandrel through the cone-pulley,
. ing to aceom modate uneven surfaces or knots in the wood, the counterbalanced swinging frame always holding the feed-saw against the I wood, no matter what kind of surface the wood may have or what its thickness, if not greater than the capacity of the machine.
Any suitable belt-shifting device is provided for belt 17. Preferablyacombined belt shifter and tightener is used, consisting of the main frame or body 39, having arms carrying flanged pulleys 40, which rest on the upper length of the belt 17, the frame by reason of its weight holding the belt tight upon the cone-pulleys. A spool 41 is mounted on one bottom sill of the inner frame opposite said body 39, and the grooved pulley 42 is mounted on the opposite sill of' the inner frame opposite said spool 41. A cord or connection 43 is Wound on said spool, passes around said pulley 42, and at its opposite ends is secured to opposite sides of the central portion of said body 39, so that the said spool is rotated in opposite directions. The belt-shifter will be thrown toward and from the spool through the medium of the connection 43 and pulley 42, thereby shifting the belt on said cone-pulleys and varying the speed-of rotation of cone-pulley16'and consequently of the feed-wheel. The belt-shifter slides back and forth on a rigid rod 43. The spool 41 is mounted on shaft 44, extending to the. front 7 end of the machine and provided with handwheel 45, whereby the spool 41 can be turned in either direction to operate the belt-shifter to cause the feed-wheel to rotate fast or slow. The shaft is provided With'joint 44' to allow the shaft to extend upwardly and to swing laterally independently of the spool 41 and to allow the feed-frame to swing independ ently of the upper portion of said shaft. A flanged gear-wheel 46 is secured on a shaft 44 and meshes with rack 47, pivoted at its lower end at 45 to upright 9 of the feed-frame, so that its upper end can swing laterally within yoke 46'. By this means the up-and-down' swing of the feed-frame does not affect the operation of gearing 46 and 47, and theflanges of the gearing hold it on the rack. The gear 46 is thrown out of gear with the rack bylifting the upper end of the shaft 44out of one notch, holding said gearing in engagement-into another notch, which will hold the gears apart, said gearing 46 and 47 being so arranged in connection with the belt-shifter that when the movable feed-frame swings up to receive a large piece of timber the controlling-gearing of the feed-saw is connected to feed slowly and when the feed-frame-drops to feed forward a small piece of timber the speed of the feed-saw is proportionately increased. This mode of operating the shaft 44 is not absolutely necessary, as the said shaft can be op erated by hand-wheel 45. Consequently the gear 46 is longitudinally movable on shaft 44, so that it can be thrown out of gear with rack: bar 47.
The many advantages and automatic action of this machine are obvious and ofgreat utility. 7
It is evident that various changes might be made in the form, arrangement, and constructions of the parts described without departing from the spirit and scope of my invention. Hence I do not wish to limit myself to the constructions herein set-forth.
