Specification of Letters Patent.

Patented Jan. 2, 1906.

Application filed June 13, 1904. Serial No. 212,317.

T at whom it may concern:

Be it known that 1, JOHN PETERSON, of St. Paul, Ramsey county, Minnesota, have invented certain new and useful Improvements in Hay and'Manure Gatherers and Loaders, of which the following is a specification.

My invention relates to that class of farm implements shown and described in Letters Patent of the United States issued to me September 13, 1898, numbered 610,609; November 12, 1901, numbered 686,532, and a certain pending application filed June 22, 1903, serially numbered 162,513.

The object of my invention, primarily, is to provide means for looking a loaded fork or gatherer in a raised position to dispense with the necessity of holding it in such position while it is being swung from the point where it is loaded to the dumping-place.

A further object is to provide an improved fork which can be easily and quickly manipulated to gather and discharge its load.

Other objects of the invention will appear from the following detailed description.

The invention consists generally in various constructions and combinations, all as hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a perspective View of a gathering and loading apparatus embodying my invention. Fig. 2 is a plan view of an improved form of a gathering-fork. Fig. 3 is a side view of the same. Fig. 4 is a detail view on the line y y of Fig. 3. Fig. 5 is a detail view showing the manner of supporting the carrying wheels or truck of the fork. Fig. 6 is a sectional view on the line a: w of Fig. 5. Fig. 7 is a detail view showing the manner of connecting the horizontal base-timbers to the upright mast. Fig. 8 is a detail view of the mechanism for automatically locking the gathering-fork in its raised position. Fig. 9 is asimilar view showingthelockingdevicepartiallyunlocked. Fig. 10 is a vertical sectional View of the locking device, showing the fork in the trip-lever. Fig. 11 is a sectional view on the line a n of Fig. 8.

1n the drawings, 2 represents a suitable baseplate, whereon an upright mast 3 is arranged. A horizontal or base timber 4 is secured to the plate 2 at one end by any suitable means, as by clevises 5, and a similar timber 6 is secured on said base-plate on the other side of the mast in a corresponding manner, except that I prefer to provide only one clevis for the timber 6 to allow it to be swung back and forth toward and from the other timber to allow the apparatus to be moved through a doorway or gate. A cross-timber 7 connects the timbers 4 and 6 and is adjustably secured thereto at its ends. The opposite ends of the timbers 4: and 6 from the base-plate are held in place by means of Weighted boxes 8, that rest upon the ends of the timbers and are held in place thereon by bars 9, that are secured to the bottoms of the boxes.

The top of the mast 3 is connected with the outer ends of the timbers 4 and 6 by bracebeams 10 and 11, that are attached to a pin 12 in the top of the mast and have their opposite ends inserted into recesses 13 in the box 8 and bearing upon the contiguous ends of the basetimbers. A boom 14 is pivoted on the mast 3, near the lower end thereof, and a block 15 is provided at the top of the boom, and a rope 16, secured at one end of the lower portion of the boom, passes through said block and around a pulley 17 at the outer end of the boom and from thence to the top of the boom, where the end of the rope is secured. By means of this rope the operator can adjust the boom at any desired angle with respect to the mast.

A hoisting-cable 18 passes under a pulley 19 at the base of the boom and over an idle pulley 20 near the base and from thence over pulleys 20 and 21 in the outer end of the boom to a block 22, wheretheend of thecable is secured. This block is provided at its lower end with a loop 23, wherein the shank of a hook 2 1 is swiveled. The head of the shank within the loop is provided with a lug or projection 25 on one side that engages the sides of the loop and limits the rotary movement of the hook therein. This construction is shown clearly in Fig. 11, where it will be seen that the hook may make nearly a complete revolution sufficient to allow the fork to be swung easily to the desired working point, but will prevent any unnecessary rotary movement of the fork that would tend to twist the rope.

Between the pulleys 20 and 21 in the outer end of the boom is asocket or recess 26. wherein a block 27, triangular in cross-section, is mounted on a pivot-pin that is fixed with respect to the boom. The triangular shape of the block 27 will cause it when struck by the jaws to assume a proper position to pass between them. The shape of this block may be varied, if preferred. On the upper end of the block 22 jaws 28 and 29 are pivoted. These jaws have tapered upper ends and notches 31, that are adapted to receive the triangular block 27 and support the block 22 and its load in araised position. A U-shaped spring 32 is mounted on the jaw 29 and incloses the other jaw and is held under tension against the same by a pin 33. A loop 34 limits the separation of the jaws, and aforked lever 35, mounted on the jaw 28, has curved surfaces 36, that engage-pins 37 in the sides of the jaw 29 and tend to press the said jaws apart when the lever is drawn downward. A suitable ropeguide 38 is preferably provided on the jaw 29. The outer end of the lever 25 is attached to a cord 39, by means of which the operator can separate the jaws and allow the load to drop. I have found where power is employed to operate the gathering-fork or loader that a device of this kind is very desirable. As soon as the fork is loaded it is raised sufficiently for the locking device to perform its functions and then the power may be released from the fork and the boom swung around to the desired dumping position. Without this locking device it would be necessary to keep the power on the fork during the time that it is being swung to the point where the load is discharged.

The fork which I prefer to employ in connection with this apparatus is shown in Figs. 2 and 3; but I may use the locking device in connection with the fork designed particularly for handling hay or straw, as shown in my pending application above referred to. In Fig. 2 of the drawings, 40 represents the forkhandle having bars 41 secured thereto at one end and projecting beyond the end of the handle and connected by cross-bars 42, having suitable truss-rods 43. The fork proper is arranged between the ends of the bars 41 and consists of an endbar 44, whereto a series of tines 45 are secured. These tines are curved in substantially the manner shown in Fig. 5 and in my prior patents and are connected by cross-rods 46. A rack-bar 47 is secured

to'the bars

44 and 46 at the middle of the fork, and the teeth of said bar are engaged by a latch 48, carried by the handle 40. The fork is provided with studs 49, whereon the ends of the bars 41 are pivoted, and a bail 50 is also pivoted on said studs, preferably between the fork and the bars 41. I prefer to provide pivoted stops 51 on the fork that are adapted to swing out into the path of the bail and hold it in an inclined position, as indicated in Fig. 3, to prevent it from dropping down upon the ground and digging into the straw or dirt when the fork is drawn backward. To render the fork more easy of manipulation, I prefer to provide trucks 52, arranged between the outer tines of the series and supported on pins 53, that pass through straps 54, secured on said tines. I prefer to provide a series of holes 55 in said strap to allow the adjustment of the trucks therein and vary the height of the tines from the ground, according to the character of the work. On each side of the fork I prefer to provide guard-plates 56, which serve to prestarting the horses or other power will gather up the load. The power being still applied to the hoisting-cable after the fork is loaded it will be raised from the ground and by the operation of the locking device secured in its raised position. The hoisting-cable can then be slackened and the boom swung around until the fork is over the dumping-place. The operator will then trip the lever 35, release the fork, and perform the dumping operation. The operation described may then be repeated It will be noted in connection with this device that there is no necessity of driving anchoring or guy rope stakes into the ground, the entire apparatus being supported in a working position by means of the bracingbeams and the weighted boxes. The apparatus can therefore be set up much more readily and can be moved from place to place with very little labor and in a short space of time.
