HAY-CARRIER.

Application filed June 3,

To all whom it may concern:

Be it known that 1, WILLIAM GUTEN- KUNsT, a citizen of the United States, residing at Milwaukee, county of Milwaukee, and State of Wisconsin, have invented new and useful Improvements in Hay- Carriers, of which the following is a specification.

This invention is an improvement upon my prior Patent No. 1202182, Oct. 24, 1916, for hay carrier. I

This invention relates to hay carriers and is particularly directed to improvements for automatically locking the mechanism in position upon a track and for improved means for gripping the elevating cable. 7

Objects of this invention are therefore to provide a hoisting carrier with improved means for both positioning the carrier upon the track and looking or gripping the cable, and also to provide improved means for correlating these functions.

In the drawings:

Figure 1 is a side elevation of the hay carrier in position upon the track.

Fig. 2 is a similar view partly broken away to more clearly show the internal mechanism, the gripping means being open.

Fig. 3 is a view illustrating a section taken approximately upon the central Vertical plane transversely to Fig.2.

Fig. 4 is an elevation of a part of the locking mechanism which is rigidly connected to the track.

Fig. 5 is a bottom view of the structure shown in Fig. 4.

The track 1 may be of the ordinary construction, such for example, as a double pair of rails as shown in Fig. 3. Upon this track a pair of trucks 2 and-3 are arranged to run, each of the trucks carrying pairs of flanged wheels 4 and 5. 'These trucks have projecting arms 6 and 7 which are bolted to the traveling frame 8, the frame 8 comprising a pair of substantially similar open work plates. The plates 8 have lower outwardly flaring circular flanges 9 formed integrally therewith. Upon these flanges 9, the hoisting mechanism is pivotally mounted and is adapted to freely turn inany desired position. This pivotal mounting is secured by having the hoisting mechanism provided with annular flanges 10 and 11 which are guided between the flanges 9 and lugs 12, such members 9 and'12 being formed integrally with the plates 8 of the truck.

The upper part of the hoisting mechanism specification of Letters Patent.

is carried between plates 13 and 14 which are formed integrally with the previously described annular flanges 10 and 11 and may conveniently be formed so as to each include one half or approximately so, of these lengths. These plates 13 and 14 are spaced apart by suitable lugs and are secured together by bolts passing therethrough. At the left hand corner, Figs. 1 and 2, between the plates 13 and 14 is mounted the upper pulley 15 over which the hoisting rope 16 passes. The outwardly extending portion of the rope after passing the pulley 15 is adapted to be hitched to a team, or otherwise manipulated, the other end 17 of the rope 16 is gripped between clamping members 18 which have a ball and socket joint 19 with a lever 20 which is pivoted at 21 between the lower right hand corners of the plates 13 and 14 as shown in Figs. 1 and 2.

The loop 22 of the rope 16 passes around the pulley 23 of a block 24 which comprises a main body composed of half sections suitably bolted, or otherwise secured together. These. sections carry upper guiding pulleys 25 which are carried between guiding arms 26. The lower pulley frame 27 may be loosely connected with the main body of the block by means of a spring pressed catch 28 tegrally with the lower pulley frame 27.

.The lower pulley frame 27 carries guiding arms 30 which may comprise outwardly extending loops through which the rope 16 passes. Suitable hooks 31 and 32 are proyidgd for engaging the hay fork or other The rope 16 passes between gripping jaws 33 and 34 which are positioned between the plates 13 and 14 and are guided in a downwardly converging direction by means of lugs 35 and 36 projecting laterally from the gripping jaws 33 and 34 and guided in downwardly converging slots 37 and 38 formed in each of the plates 13 and 14. These jaws are loosely joined by means of a link 39 so that motion of one jaw will be imparted to the other jaw. The jaw 34 is provided upon its outer side with rack teeth 40 which are engaged by teeth 41 formed upon the free end of the lever 20. The mechanism as thus far described illustrates means whereby the tension of the-rope 16 is transmitted to the lever 20, and through the teeth 40 and 41, is transformed into gripping motion or downward motion of the jaws 33 and 34 to thereby engage and look the rope 16.

To release the gripping means 33 and 34, suitable means are provided which may be actuated from several sources. These means comprise a plunger 42 provided with extensions at its lower end which straddle the lever 20 and are provided with a bottom member 43 which is adapted to engage the lower portion of the lever 20 when the plunger 42 is in elevated position and thereby release the gripping jaws as shown in Fig. 2. The plunger 42 passes through the upper portion 44 of a second plunger 45 which latter plunger is provided with a shoe 46 at its lower end adapted to be engaged by the block 24 when the block is in elevated position. The upper part of the plunger 42 is provided with an enlarged head 47 whose purpose will later appear. 1

One of the plates 8 of the carriage or truck carries a pivot pin 48 upon which are mounted a pair of bell crank levers having arms 49, 50 and 51, 52, respectively. The arms 50 and 52 are bifurcated and straddle the plunger 42 and are positioned beneath the enlarged head 47 thereof, the arms 50 and 52 resting in normal position one upon the other.

When it is desired to release the rope 16 manual means may be used as illustrated in Fig. 1 comprisinga rope 53 which is attached at one end to a lever 54 pivoted at 55 to the frame 14. The other end 56 of the lever 54 passes loosely through an eye 5'? formed integrally with the plunger 45. Thus when the rope 53 is pulled, the plunger 45'is elevated, the upper end 44 engaging beneath the lever 52, and through the intervention of the lever 50, enlarged head 47,

and plunger '42, elevating the lever 20 and thereby releasing the locking jaws 33 and 34 from engagement with the rope 16.

In order to temporarily lock the carriage in one position upon the track, a socketed member 58 is bolted to a portion of the track at the point at which it is desired to have the carriage temporarily locked. This member 58 comprises a pair of tapered surfaces 59 upon each side of a recess 60, the tapered faces 59 being presented outwardly as shown in Fig. 3 and the recess 60 extending only part way up the outer surface of this socketed member 58. When the truck or carriage passes in front of the member 58, the arms 49 and 51 of the bell crank levers ride along the inclined surfaces 59 and cause their arms 50 and 52 to rise, thereby elevating the plunger 42 and releasing the locking mechanism. When the central position has been reached, the arm 51 drops into the socket 60 thereby temporarily locking the carriage or truck in position upon the track. The arm 49, however, rides upon the upper portion of the surface of the member 58 and thereby keeps the arm 50 of this bell crank lever in elevated position as shown in Fi D 3, such arm 50 engaging beneath the head 47 of the plunger 42 and thereby holding the locking mechanism open.

' The operation of the device is asfollows.

After'the load has been properly engaged,

the rope. 16 is pulled, usually in a direction parallel to that of the track 1; the carriage 8 being held temporarily in position by means of the lever 51 which is caused to seat in the socket 60 by means of the'spring 51', 7

When the block 24 approaches the upper limit of its'motion, it engages the shoe 46 and forces the plunger 45 upwardly, the

is transmitted directly to the gripping means thereby aiding them in their downward motion and causing them to securely engage the rope and lock the load against further downward motion. The carriage now continues to travel along the track due 7 to the tension in the rope. When the carriage has arrived at the desired position, the rope 53 is pulled. This causes an upward motion of the plunger 45 and causes the upper portion 42. to raise the lever 52 and thereby raise the lever 50 which is seated upon the lever 52. 'This upward motion of the lever 50 is transmitted to the plunger 42 which in turn transmits it to the lever 20 causing such lever to raise the locking jaws and release the rope allowing the load to be lowered.

When the carriage is drawn to a position opposite the locking member 58,'the lever 51 snaps into position in the socket 60. and locks the carriage in position while the lever 49 rides upon the upper portion of the member 58 and elevates the lever 20 through the associated mechanism and unlocksfthe gripping jaws 33 and 34 from the rope 16 allowing the block 24 to descend.

It will thus be seen that a hoisting carrier has been produced in which exact adjustment of the parts is-not necessary to perfect operation of the device, for. example, the

carriage or truck may be passed along the track until the locking lever snaps into its appropriate socket thereby positioning the carriage, It is not necessary that the carriage be drawn to an exact position of adjustment along the track before the automat1c release operates, but it may be pulled along the track at any desired rate and the mechanism will automatically function at the proper time.
