WILLIAM cUTENKUNsr, or MILWAUKEE, WISCONSIN.

HAY-Canaries.

To all whom it may concern:

Be it known that I, ILL AM GUTEN- nonsr, a citizen of the United States, residing at the city of Milwaukee, county of Milwaukee, and State ofWVisconsin, have invented new and useful Improvements in Hay-Carriers, of which the following is a specification.

My invention relates to improvements in hay carriers, and it pertains, more especially among other things, to the mechanism for locking the carrier in a fixed position to its supporting track as the load is being raised and for automatically releasing the carrier from such fixed position as the load reaches the limit of its upward movement.

My invention also pertains to the device for gripping the hoisting cable and for manually releasing such cable from its gripping jaws after the load has been dis engaged therefrom, whereby the fork suspended from the hoisting cable may be drawn down and again loaded with hay or other similar material preparatory to being raised and conveyed to a place of deposit.-

My invention is further explained by reference to the accompanying drawings, in which t Figure 1 is a side view thereof as it appears suspended from an ordinary track. Fig. 2 is a similar view to that shown in Fig. 1, part broken away to show the interior construction. Fig. 3 is a transverse vertical section drawn on line a, a: of Fig. 1. Fig. 4 is a plan of that portion of the hold ing mechanism which is rigidly connected with the carrier supporting track, and Fig. 5' is a side view of the device shownv in Fig. 4.

Lil-te parts are represented by the same reference numerals throughout the several views.

1' represents a track of ordinary construction upon which the carrier is suspended, and by which the carrier and load are brought above the place of deposit.

2 represents the main frame of the carrier which is provided at its respective ends with a pair of rollers 3, 3, by which it is suspended from the track. The rollers 3, 3 are connected with the frame 2 by journal bearings 1, l in the ordinary manner.

5 is a tackle block which is provided with a pulley 6 for the reception of the hoisting cable 7. The tackle block is also provided with hooks 8 for the reception of a hay fork Specification of Ietters Patent. Patented 0C1 24, 1916. Application filed October 18, 1915. Serial No. 56,406.

orsling, not shown, which may be of ordinary construction. The tackle block 5 is further provided with two pairs of loops 9, 9 and 10, 10 which serve as guide bearings for the hoisting cable? as said cable -7 passes around and beneath the pulley 6. Theupper end 11 of the tackle block forms a block or contact bearing, which as the load is raised is brought in direct contact with the opposing block 12. The opposing block 12 is rigidly connected with the vertical bar 13, whereby as said blocks are brought together the bar l3 isautomatically raised. As the bar 13 is thus raised it is brought in contact with the arm 40 of the two armed lever i1, whereby the upper arm 42 is thrown back against the recoil of the spring 43 shown in Fig. 3. As the arm 42 is thrown back it is'disengaged from the notch 4% of the member 15, shown in Fig. 5, whereby the carrier 2 is free to be moved forward on the track 1 above the place of deposit. Preparatory to raising the load the arm or member as is caused to traverse one of the inclined surfaces @6 of said member 45 until it is'brought opposite said notch or recess ail, when it is thrown into said notch or recess by the action of the spring 13 shown in Fig. 3.

I have provided two different means for disengaging the carrier frame 2 from the track 1. The carrier frame 2- is disengaged from the track 1 first by contact of the block 11 with block 12, as hereinbefore described, whereby the vertical bar 13 is raised until it is brought in contact with the arm 40 when the arm 42 is thereby drawn back out of engagement with member 45, as previously described. As a second means of thus disengaging the carrier frame 2 from the track a downward pull is manually com municated to the cable 17 whereby motion is communicated through the arms 17 and 15 and loop 14 to said vertically moving bar 13,and from thence to said arm 40 as pre viously described, whereby the carrier frame 2 is also in like manner disengaged from its track, the member 42 being thereby withdrawn from-the notch 44, which object can be thus accomplished as the load reaches any point of elevation above-the wagon which is being unloaded. It will be understood that as the carrier is thus moved along the track the arm 48 will be brought in contact with one of the opposing ends of the stationary member 45, whereby said arm 48 will be moved toward the left, relatively to its supporting frame 2, reference being'had to Fig. 1, whereby the triangular member 49 will be tilted toward the left on the pivotal bolt 50, motion being communicated to said triangular member .49 from said arm 48 through the pivotal bolt 51. As the triangular member 49 is thus moved the segmental gear is thrown down in the direction indicated by the arrow thereon, when motion is communicated therefrom to the gear 22, said gear 22 being turned in the direction indicated by the arrow, when motion is communicated to the tooth bar 23, when motion is communicated from said bar 23 to the bar through the connecting link 26, whereby the cable 7 which is rigidly gripped between the clutch members 24 and 25 is released. The members 24 and 25 are provided with lateral projections 29,29 and 30, 30, which have slidable bearings 31, 32 and 33 in the inclosing frame, whereby said grip members are simultaneously thrown back and away from the hoisting cable 7 as they are raised. The clutch mechanism 25 is forced in contact with the hoisting cable 7 as it descends by the action of the spring Cir 34, and said spring 34: is pivotally supported from the carrier frame by the pins 35, 35. The gear 22 is revolubly supported from the carrier frame upon the shaft 36, and the two armed lever ll is pivotally supported from the carrier frame upon the pivotal bolt 36. The spring 43 is connected with the two armed lever 41 by the bolt 36. The hoisting cable 7 is connected at one end with the triangular member 49 by the clamping mechanism 38 in the ordinary manner, when it passes from theredown beneath the pulley 6 and from there up and over the pulley 39 when its opposite end is connected with the hoisting power, which may be a team or other source of power.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

1. In a device of the described class, a carrier frame provided with a. plurality of downwardly converging recesses, a plurality of gripping members having slidable bearings in said recesses, a hoisting cable having an upward and downward movement between the opposing surfaces of said gripping members, and means for moving said gripping members into and out of gripping contact with said hoisting cable.

3. In a device of the described class, a carrier frame provided with a plurality of downwardly converging recesses, a plurality. of gripping members having slidable bearings in said recesses, links connected with said gripping members, a hoisting cable having an upward and downward movement between the opposing surfaces of said gripping members, and means for both automatically and manually moving said gripping members into and out of gripping contact with said hoisting cable.
