HAY-RICKE R.

SPECIFICATION forming part of Letters Patent No. 436,741, dated September 16, 1890. Application filed FebrnaryB, 1890; Serial no.3sa442. (Nomodeh) To all whom it 17mg concern.-

Be it known that I, DOCTOR FRANKLIN OLI- VER, a citizen of the United States, residing at San Francisco, in the State of California, have invented certain new and useful Improvements in Hay-Rickers, of which I do declare the following to be a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention has relation more particularly to hay-rickers of that class commonly known as vertical rickers or stackers, examples of this type of ricker being illustrated in Letters Patent No. 292,038, granted to me J anuary 15, 1884:, and No. 305,325, granted to me September 16, 1884.

The object of my present invention is to improve the richer in various particulars, and this object I have accomplished by the novel features of constructionhereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the claims at the end of this specification.

Figure lis a perspective view of a hay-ricker embodying myinvention. Fig. 2 is a view in end elevation. Fig. 3 is a View in central vertical transverse section, a portion of the framework being broken away. Fig. 4 is an enlarged detail view of the latch mechanism for temporarily holding the auxiliary carriage. Fig. 5 is an enlarged detail view in side elevation of one Of the carrier-trucks that serve to sustain the main carriage and adjacent parts. Fig.6 is an enlarged detail View in horizontal section through the journals of one of the carrier-trucks, showing also the manner in which these trucks are held upon the guideframe and showing some of the adjacent parts. Fig. 7 is an enlarged detail view in vertical section through one of the pivot or journal pins that serve to unite the main carriage with the trucks. Fig. 8 is a view in vertical section on line 8 8 of Fig. 7. Fig. 9 is a detail plan view of one of the j ournals of the main wheels that support the richer-frame.

The base of the main frame of my improved richer consists, preferably, of the longitudinal bars A and A, that are mortised into suitable end bars B and B, that serve as axles, to the ends of which. will be connected the wheels 0, upon which the ricker will be sustained 'in such manner that it can be freely moved from point to point. By preference the front wheels 0 will be connected to the front axlebars B by means of a journal 2, projecting outwardly from the swivel or pivot block 3, the ends of which are journaled in suitable bearing-plates 4:, bolted to the ends of the cross-bar B. From these pivot-blocks 3 project .the lugs 5, having suitable eyes therein to receive the ends of the rods 6, that project outwardly from the tongue 7, that is pivotally connected, as at 8, to the center of the axlebar B. My purpose in thus connecting the tongue or pole 7 with the pivot-blocks 3 is to permit the blocks and the wheels to be shifted in order to more readily guide the machine. The rear wheels 0 are by preference also attached to the rear axle-bar B in such manner that the wheels can be turned to a position parallel with the axle-bar B, and these wheels are preferably sustained upon a journal 10, (see Fig. 9,) provided with vertical pivot or hearing pins 11, that are journaled within suitable seats formed in the ends of the bearing-plates 12.

In order to hold the wheels 0 in proper position, I provide at the base of the journal 10 a laterally-extending lug 15,having a curved end adapted to be secured by abolt 16 to the end of the axle-bar B, as more particularly shown in Fig. 9 of the drawings, and thejournal 10 is also provided with a laterally-pro, jecting lug 17, having an eye therein adapted to come coincident with a hole formed through the end of the axle-bar B, so that when the wheel is turned to a position parallel with the said bar it may be securely held in such position by passing the bolt 16 through the lug 17, as shown by dotted lines in Fig. 9. The front wheelsO can also be turned to position parallel with the front axle-bar B by merely withdrawing the bent ends of the guide-rods 6 from the lugs 5, after which the Wheels may be turned to the desired position and can there be secured by means of a bolt 18, passing through a lug 19, projecting from the pivot-blocks 3. My purpose in thus connecting the wheels with the main frame so that they can be shifted is not merely to permit the frame to be more readily and conveniently moved from point to point, but when the Wheels are turned to a position parallel with the axle-bars the danger of the striking of the wheels next to the main-carriage by the rake-teeth that deliver the hay thereon is avoided.

Between the longitudinal bars A and A are preferably placed the diagonal brace-bars a, which serve to give greater rigidity to the frame. From each of the axle-bars B and B rises a guide-bar D, which may consist of two separate bars suitably bolted together in such manner as to leave a narrow space 20 between them, or may consist of a single bar or beam having grooves in its sides corresponding to the space 20, the purpose of this space being to admit the flanges of the wheels E of the carrier-trucks that serve to sustain the main carriage of the ricker. The guidebars 'D are bolted at their lower ends to the axle-bars B and B at points in front of the longitudinal bars A and A, and these guidebars are sustained in their vertically-inclined position by means of the vertical brace-bars 80, that are fastened at their base by suitable angle-irons to the aXle-barsB and B and at their upper ends are bolted to the sides of the guide-bars D. To the vertical brace-bars 80 are suitably bolted the inclined transverse stay-bars 81, the inner ends of which extend downwardly to a point beyond the center of the richer-frame and are suitably bolted to the longitudinal bar A. The stay-bars 81 cross each other at a point about the center of the richer-frame and are suitably bolted together, as at 82. The outer end of each of the stay-barsSl projects to a distance beyond the vertical brace-bars 80, and to this outer end is bolted the lower end of a truss-bar 83,

- the upper end of which is bolted to the guidebar D, and to this outer end of the stay-bars 81 is also bolted the upper end of a similar truss-bar 84, the lower end of which is suitably attached to the brace of the vertical brace-bar 80. By this arrangement of bracebars and truss-bars I am enabled to sustain the vertically-inclined guide-bars D much more securely than was possible with prior constructions, and it is plain that when the load of hay is carried upward on the guidebars D the strain upon these guide-bars will be resisted not merely by the vertical bracebars, but also will be distributed through the truss-bars S3 and 84 and by the brace-bars 81 to the base of the main frame. By preference also I extend between the vertical brace-bars 80 and the guide-bars D suitable cross-braces 86, which serve to give greater rigidity to these bars.

The carrier-trucks consist, preferably, of the journal-yokes 21 and 22, that straddle the inner sections of the upright guide-bars D, the ends 8 of the yokes constituting the journals for the wheels E. The yokes 2i and 22 at each side of the machine are connected together by the tie-bar 23, and the lower yoke 22 of each truck will be furnished with a socket 24, this socket serving to receive the end of the pivot or journal pin 30 of the main carriage. As it frequently happens that in the lifting of the main carriage of the elevator one side is raised more quickly than the other, I guard against the danger of the binding of the trucks upon the guide-bars under such condition by connecting each of the pivot or journal pins 30 with the trucks in such manner as to permit a vertical oblique play or movement of these pins, as seen by dotted lines in Fig. 7, and as well also a slight lateral movement thereof. Preferably this connection of the pivot-pins to the trucks is effected by forming the sockets 24 with the oblong slots 25, which will permit the pins or lugs 26, formed on the ends of the pivot-pins 30, to be inserted therein, but will guardagainst the Withdrawal of these lugs when the pivot-pins have been turned a quarterrevolution and have been bolted to the ends of the main carriage. I Preferably the inner ends of the pivot or journal pins 30 are extended through the end bars of the main earriage and are bolted to the under side of the rear longitudinal bar of such carriage. The

sockets 24 should be provided each with arecess 27 of sufficient size to permit a slight lateral movement of the ends of the pivot or journal pins 30 and the guard-pins or lugs projecting therefrom.

The main carriage, by which the hay will be raised from the ground, consists of the longitudinal bars G and H, that are suitably bolted to the end bars I, and to these bars G and H are fastened the teeth K. By preference the bar G. is split longitudinally and its center portions 9 and g spread apart and separated by suitable blocks, so as to truss and strengthen the bar, and at the same time form aconvenient space within which can be held the casting of the lever that controls a locking-latch of the auxiliary carriage, as will presently more fully appear. Beneath the under side of the longitudinal bar His ex tended, preferably, a truss-rod h, the ends of which are suitably fastened to the endsof the bar H. The upper yoke 21 of each of the carrier-trucks is provided with a suitable extension 40, in which is journaled the pulley 41, around which will pass the main liftingcord R, that passes also around a pulley 42 carried at the end of the tilting bar L, that is pivoted at its inner end to a lug 45, projecting from the lower yoke and each of the carrier-trucks. Each of the tilting bars L has connected thereto a slotted bar M, the upper end of which sustains the pulley 42, and within the slot of which bar extends the pin TL, projecting laterally from the corresponding end bar of the main carriage, and in this slotted bar M is formed a series of perforations m to receive a pin m, that serves to limit the movement of the pin a within the slot of the bar M. Each lifting-rope R which passes around the pulleys 41 and 42 has one end connected to the pulley-frame d at the top of the vertical guide-bar D, while the main portion of the rope passes around a suitable pulley 48, held in said pulley-frame,-

and passes thence downward and around a sheave 49, fastened to the cross-bar B, and thence to the singletree of the draft-horse.

To the rear ends of the teeth of the main carriage are pivotally connected the teeth 0 of the auxiliary carriage, the rear ends of these teeth 0 being attached to the cross-bar 0, that is preferably strengthened by splitting it centrally and separating its central por tions. The teeth 0 of this auxiliary carriage are held normally at an acute angle with respect to the teeth of the main carriage by means of a bail or bent bar 60, that is pivotally connected at its ends to the transverse bar 0 of the auxiliary carriage and extends through a suitable loop 61, fastened to the under side of the main carriage, as more particularly shown in Figs. 1, 3, and 4 of the drawings. At the base of thisloop 61 is placed a catch-pawl 62, that is held within a suitable socket 63, and is pressed normally downward, as seen in Fig. 4, by means of the coiled spring 64, and through the side of the socket 63 extends a throw-off lever or trigger P, that is pivotally mounted, as at 10, within a lateral extension 65 of the same casting that comprises the socket 63, this lateral extension of the casting being suitably bolted between the sections 9 and g of the transverse bar G. The beveled end of the pawl 62 permits the bail 60 to readily pass behind the pawl, and when in this position it will serve to hold the teeth 0 of the auxiliary carriage at an acute angle with respect to the teeth of the main carriage until by the movement of the releasing lever or trigger P the pawl 62 is lifted and the bail 60 is permitted to pass from eugagement therewith, thereby allowing the teeth 0 of the auxiliary carriage to drop down ward in such manner as to discharge the hay therefrom, as will presently more fully appear. From the end of the trigger P a suitable tripping-cord will pass to the ground.

From the foregoing description it will be seen that if the main carriage be assumed to be in position shown in Fig. 2, with the points of its teeth resting upon the ground, and the draft-horse be started to raise the load of the carriage for'the purpose of depositing it upon a stack or rick the strain of the lifting-ropes R will first cause the tilting bars L to give an initial tilting action to the main carriage about its journal-pins, causing the teeth of this carriage to assume a vertically-inclined position, as seen by dotted lines in Fig. 2, after which the further strain upon the lifting-rope will cause the main and auxiliary carriages to be raised to the desired height. In order to secure this initial tilting action of the main carriage, which serves to throw the load backward in position against the teeth of the auxiliary carriage, I provide a check-arm 90, secured to the center of the bar 0 of the auxiliary carriage, as seen in Fig. 3 of the drawings, this check-arm being preferably curved at its outer end to engage with a suitable loop or stirrup 91, cast on or attached to the upper part of the latch-guide 92, that is bolted, as at 93, to the longitudinal bars A and A of the main frame.

By preference the bolt-holes of the latchguide 92 are formed as long slots, so as to permit the adjustment of this latch-guide and of the stirrup to secure the release of the check-arm 90 at the proper time. The latchguide 92 is curved upon its upper face,'so as to direct the curved end of the check-arm 90 into the stirrup 91, and also cause the proper swinging of the auxiliary carriage necessary to bring the bail in loop 60 into proper position behind the pawl 62. Hence it will be seen that when the load of hay is lifted the main carriage will receive a tilting action, as before described, thereby throwing the load of hay against the teeth 0 of the auxiliary carriage, and when the main and auxiliary carriages are lifted to the desired height the tripping lever or trigger P will be operated to raise the pawl 62 and permit the weight of the load of hayagainst the teeth 0 of the auxiliary carriage to swing these teeth backward and downward, thereby permitting the hay to discharge onto the rick. In the ordinary operation of stacking the hay the pin m of the slotted bar M will be set at the base of the slotted bars, and in such position will permit the tilting action of the main and auxiliary carriages after these carriages have been raised and after the tripping-lever P has been operated to permit the release and outward movement of the auxiliary carriagethat is to say, when the release of 'the auxiliary carriage has been effected and the load of hay slides from the teeth K of the main carriage onto the teeth 0 of the auxiliary carriage the weight of this load will cause a tilting action of the main and auxiliary carriages, this action being permitted by the movement of the pin 12 Within the slots of the slotted bars M. When it is desired to top out the stack, it is not desirable that the entire load of hay should be discharged at once from the carriages, and in order to temporarily retain the hay upon the carriages after they have been raised to the desired height the pins m are set in front of the pins u, that pass through the slotted bars M, so that the movement of the pins 11 is arrested, and the tilting of the carriages, after they have been raised to the desired height, is prevented, thereby retaining the hay upon the teeth of the auxiliary carriage to be taken off as desired by the builder of the stack.
