Patented sept. 29, 190s.

To all whom it may concern:

Be it known that I, MATHIAs THURsToN, a citizen of the United States, residing at Stryker, in the county of Williams and State of Ohio, have invented certain new and useful Improvements in Hay-Carriers, of which the following is a specification.

My -invention relates to the class of hay carriers in which the carrier proper is adapted to move back and forth upon a track or way and the elevating rope leads from the carrier in a line transverse to the track or way. p

The objects of the present invention are as follows: First, to rovide a carrier wherein a cross-draft is app ed, and second to provide means for locking the elevating rope and the load carried thereby at rany point of elevation of the load or the instant the pull upon the elevatin rope lis released. I attain these main objects and other minor objects, by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side view of the carrier mounted upon the track or way and showing the elevating rope properly threaded in the carrier. Fig. 2 is an elevation of the carrier taken from the same point of view as Fig. 1, but in this figure the side of the'carrier has been removed'and parts are shown in section. Fig.' 3 is an elevation of the carrier mounted upon the track or way, said view bein taken at right angles to the line of view in igs. l and 2. Fig. 4 is a cross-section on line 4-4, Fig. 1. Fig. 5 is an elevation of the carrier mounted upon the track or way, showing the v spaced relationshi carrier threaded with the elevating rope, the same sustaining the load, the rope-being locked and the side of the carrier ame removed. Fig. 6 is a vertical section on line 6-6, inFig. 5. Fig. 7 is a vertical section upon the line 7-7, in Fig. 1.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

In the accompanying drawings, l and 2 represent the spaced side members of the lower frame section, which are held in proper with reference to each other by interpose members hereinafter d escribed and tied together by suitable clamping bolts.

The side members are alsovse-` cured in proper spaced relationship with ref-v erence to each other, by theconnected track frame 3, which is connected to the lowerv frame members 1 and 2 by suitable clamping bolts 4. The parts just above described are common in hay elevators of this class, except as to their detailed construction hereinafter described.

The side members 1 and 2 are provided with the lugs 5, upon which lugs are pivotally mounted the main pulley carrying levers, which levers consist of the upper portions 6 and the lower portions 7 said portions 6 and 7 being located at an angle to each other as best illustrated in Fig. 5. For the purpose of providing suflicient room, between the lower frame members 1 and 2, to receive the main pulley carrying levers and at the same time providing for bringing the members near together,beyond the points where the levers 4are located, said side members are chambered as best illustrated in Figs. 4 and 6.

The main pulley 8 is mounted upon the axle 9 ormore specifically upon the roller bearings 10 shown in the drawings, which axle extends through the curved slots 12, said axle being carried by the pivoted levers consistingv of the parts 6 and 7. Below the' main ulley 8 is located the rope grip actuating ever 13 which lever is provided with the integral angled portions 14, which extend upward or toward the pulley 8 and their top or upper ends provided with the recesses 15, into which recesses the lower ends of the portions 7 of the levers are seated. To the upward extended an led portions 14 are pivotally connectedvthe inks 16, which links are pivotally connected to the movable rope gri 17.

For the purpose of holding the rope-grip l 17 in proper relationship with reference to the fixed rope-grip 18, the suspending links 19 are provided, which links are pivotalljy7 connected to the movable rope-grip 17, at their bottom or lower ends, their top or upper ends ivotally connected to the side members 1 an 2 of the lower frame'. Y The fixed ropegrip 18 is held in lixed relationship with reference to the frame members 1 and 2 by means of suitable clamping bolts 20 or their equivalents. Below the rope grips 17 and 18 are located the rope guide rollers 21, which rollers are for the purpose of holding that portion of the ro e'22 between the upper surfaces of the rol ers 21 and the bottom or lower ends of the rope grips 17 and 18 in substantial alinement with the clamping faces of said rope-grips, by which arrangement the entire length of the gripping surfaces of the ro e grips can be better utilized to grip and hold the rope. l

The elevating rope 22 is secured at one end to the clevis 23 or its equivalent, which clevis is attached to the catch 26 hereinafter described. In .use the rope is threaded through the sling pulley blocks 24 or any elevating head commonly used in hay elevators of this class. The rope is extended or threaded between the rollers 21, the ropegrips 17 and 18, and thence over the pulley 8 passing the roller 25 from whence it is exe tended any desired distance to the point where the hitch is made to lift the load.

For the purpose of temporarily holding the lever 13 in an elevated position or in the position illustrated in Figs. 1 and 2, said lever is provided with the pivoted catch 26, which catch is provided at its upper free end with the hook 27 which hook is adapted to engage the cross rib or bar 28 said cross-rib or bar being connected to the frame members 1 and 2 in any convenient and well known manner.

For the purpose of preventing the catch from becoming disengaged from the rib or bar 28 by the weight of the sling or other device or devices used in elevating loads of hay or other material, the spring 29 is provided, =which spring is so tensioned that it will hold the hooked end of the catch 26 in engagement with the rib or bar 28 and for the purpose of adjusting the tension of the spring the adjusting screw 30 is provided, which adjusting screw is extended through a screw threaded aperture in the spring housing 31. The tension of the spring 29 is only for the purpose of holding the catch 26 in en gagement with the rib 28 during the time the sling is unloaded or empty, but when a load is elevated the pull will be sulcient to overcome the tension of the spring and disengage the catch 26 for the purpose hereinafter described.

It will be understood that when the lever 13 is in the position illustrated in Figs. 1 and 2 the right angled portions 14 will be held in position to release the elevating rope, owing to the fact that the rope grip 17, is moved away from said rope and the stationary grip 18 by means of the links 16, at which time the elevating rope is free to move between the grips 17 and 18. The elevating rope 22 is illustrated as shown over the pulley 8 and when a pull is given to the elevating rope the pulley will move or be carried in the direction of the pull of' the rope, or in other words in the direction of the movement of the elevating rope for a limited distance, which movement is permitted by connecting the axle 9 to the portions 6 of the rock levers, which rock levers consist of the portions 6 and 7. Said levers are pivotally attached to the frame members 1 and 2 respectively by which arrangement, a limited oscillating movement of the levers is permitted, which in turn permits the pulley 8 to move back and forth for a limited distance, following the movement of the elevating rope. When the lever 13 is pulled or held down by the weight of the load or held in position illustrated in Fig. 5, the rope grip 17 will be moved into position to clamp the elevating rope between said rope grip 17 and the stationary grip 18, at which time there can be no downward movement of' the load but when a pull is given to the elevating rope ol su'llicient degree to elevate the load the pulley 8 will be moved into the position illustrated in dotted lines Fig. 5, which moves the lower portions 7 of the pulley carrying levers toward the stationary rope grip 18 and moves the rope grip 17 away lrom said stationary rope grip 18, by reason ol the movement of the lower ends ol' the portion 7 of the pulley carrying levers, said portions being seated in the recesses 15, thereby moving the angled portion 14 with the portion 7 olf the main pulley carrying levers.

It will be understood. that the same initial pull which releases the hook 27 from the bar 28 will also move the pulley 8 into the position shown in dotted lines in Fig. 5, which will, by means of the connecting mechanism, release the grips from the elevating rope and if this` pull is continued the said grips will remain unlocked but il` at any time slack is given to the elevating rope 22 the pulleys 8 will move into the position shown in full lilies in Fig. 5, and thus permit the downward pull upon the lever 13, by reason of the weight ol the load, to again lock the grips upon the rope.

It will be understood that the outer end of the lever 13 must be elevated. when the angled portions 14 are moved as just above described, and in order that this movement can be brought about the 'force exerted upon the pulley 8 when the pull is given to the elevating rope must be greater than the down pull of the rope upon the lever 13. 'lhis action takes place by reason olE the di'll'erence in the down pull of the rope upon the lever 13, and the pull of the rope upon the pulley 8. The catch 26 will be held out of' engagement with the bar or rib 28 during the time a load is being elevated or when the elevating rope is slackened by reason of connecting said elevating rope to the pivoted catch 26, which catch is held in a position to hold its hooked end away from and out of engagement with the rib or bar 28.

It will be understood that the instant the elevating rope is given any slack the levers carrying said pulley will rock upon their pivotal points, which rocking movement throws the outer or free end ol the lever 13, thereby bringing the rope grip 17 into action by means of the links or straps 16, thereby i l (l (l clamping the rope and holding the load against downward movement. y

It will be understood that in someinstances it may bedesired to lower the load after it has been elevated and in order that the rope may not be clamped when slack is given to it, the lever 13 is held in elevation by means of the auxiliary pivoted catch 32, which catch is provided with the lower hooked end.33, which hooked end engages the notch 34 formed in one side ofthe lever 13. The auxiliary catch 32 is provided' with the right angled integral eye-bar 35, which right angled l integraleye-bar is pivotally connected to one of the side members of the lower frame.

For the purpose of preventing any accidental displacement ofthe auxiliary catch 32 it is extended a short distance above the eyebar 35 and a spring 36 is located against said upper portion, which spring is located inthe socket 37 formedv in the inner side of one of the carrier frame sections, said spring being for the purpose of normally holding the auxiliary catch 32 out of engagement with the lever 13. When it is desired to temporarily lock the lever-13 in its elevated position and release the rope grip and free the elevating rope,

the eye-bar 35 is moved downward at its outer end by a cord 3321.01' its equivalent extended downward asulicient distance to be grasped by the hand' of the operator, which downward movement throws the lower end of the auxiliary catch 32 into position to seat the hook 33 in the recess 34. The upper frame 3 carries the usual traveling wheels 38, which are iitted to the ltrack raiis 39 and of course travel upon said track rai s. y

For the purpose of preventing any accidental derailment of the carrier proper during the time it is traveling `back and `forth upon the track rails, the upper frame 3 is provided with the cross-bars 40, which crossbars are provided with upward extended flanges 41 located belowthe ianges ofthe traveling wheels 38, and extendin beyond said flanges and under the lower anges, of the track.4 If for any reason the carrier is swung greatly out of its proper position and into an angle to a vertical line or in case the said carrier is jolted or thrown upward so as to cause the traveling wheels 38 to be lifted trom the track, the said flanges 41 will come in contact with the lower flanges Vof the track and eHectually prevent derailment.

For the purpose of providing room for the heads of the track suspending device 42, the

iianges 41 are spaced as illustrated in Figs. 1, 2 and 5.
