HAY-CARRIER.

l SPECIFICATION forming part of Letters Patent No. 631,896, dated August 29, 1899. Application filed January 3, 1899. Serial uoflooplol (No has To all whom it may concern:

Be it known that 1, WILLIAM LOUDEN, residing at Fairfield, in the county of J efierson and State of,lowa, have invented a new and useful Improvement in Hay-Oarriers,of which the following is a specification.

This invention relates to hay-carriers in which an automatic brake or grip is used to catch and hold the hoisting-rope; and it consists of means whereby part of the mechanism for operating the brake may be mounted in the upper frame of a swivel-carrier and the remainder in the lower frame and swivel, together with the frames upon which they are mounted. 3

It also consists of other features, set forth in same, showing an ordinary track-wheel in place of the truck. 1 I

The carrier is constructed with an upper frame A and a lower frame B, connected together by means of a swivel O. -The upper frame is provided with'wh'eels 'D'to support the carrier on the track E and the lower frame with sheaves F, G, andH, around which the rope I passes. The sheaves F and Gare mounted in a frame J, which is arrangedto tilt or oscillate on an axle K. I

L is a brake-bar pivoted in the frame of the carrier at m and is arranged to grip the rope I on the sheave G. It has a slot N in its body, in which playsa bolt or a boss 0, connecting it to the inner end of the tilting frame J.

In the upper frame of the carrier is mounted a vertically-sliding dog P, having its'lower end made circular and its upper end forked and fitted with horizontal lugs P. In the center of the lower end of the dog P is a hole, and there is also a hole in the central part of the brake-bar L, through both of which holes a bolt Q is loosely fitted, thus connectingthe dogP and the bar L together so as to swivel around with their respective frames. When the carrier is run along the track to the stop S, the lugs P will slide up the lower inclines R of the stop S, which will lift the dog Pand will also raise the free end of thebrakebar L 05 the rope I by means of the bolt Q connecting them together. To hold them in this position, I pivota loop-shaped trip-lever T to the lower frame of the carrier at t and arrange its upper end so that it will catch under the lower end of the dog P and keep it in elevated position. The lugs P will then be held from passing out under the upper inclines Rof'the stop S, and the carrier will beheld stationary on the track in the usual manner,while the brake-bar L will be held free from the rope I. l The loop-shaped trip-lever T is preferably made in two parts and riveted together at each end by the rivets z; and it is also preferable to join their central parts together by means of a central bolt or rivet z. In Fig. l the rear side only of the triploop is shown. sheave F, then over the sheave G, then down under'the elevating-pulleys U, the lower ends of which are cut away in the drawings, then up through the trip-loop T and over the sheave H and down through the trip-loop, and thence to one of the pulleys U, where itis fas; tened in the usual manner. An adjustable stop V is usually secured to the rope between the loop T-an'd the pulley U. The pulleys U are now free to descend and be connected to the load to be elevated. Power being applied to the free end of the rope I, the pulleys U, with their load, will be elevated until the stop V comes in contact with the lower end of the loop T and raises its outer end, which will throw its upper end from under the dog P, so the dog will drop and allow the lug P to pass out under the upper inclines R of the stop S and the carrier can run along the track to the point of deposit. At the same time the free end of the brake-bar L will descend and grip the rope against the sheave G, so as to prevent the pulleys U, with their load, from descending should the rope be slackened. When in this position, the upper end of the trip-lever T will be free to swivel around the lower circular end of the dog P, as shown in Fig. 1.

The rope I is first passed over the bite until the ropewill pass down no farther" or until the toe L rests on the top of the rope. The hollow L permits the bite of the heel to extend well up toward the toe,

while the toe will come fairly on the top of the rope, and thus prevent the rope from being wedged too tightly between the brake-bar L and the sheave G. The slant of the heel will be sufficient to accommodate any moderate variation in the size of the rope, but should an extra large or small size of rope-be used a further adjustment is provided for in the axle K, upon which the tilting frame J is pivoted. The ends of this axle are fitted to slide in recesses W in the frame of the carrier, so as to adjust the frame J, with the sheave G, closer to or farther from the foot of the brake-bar L, and the axle K is held in any desired ad- 3' ustment by means of the double-nutted bolts ac, which are passed through the ends of the the carrier-frame.

axle K and also through the end walls of the recess W. In ,this Way any size of rope may be used and may be adjusted to fit the brakebar and also to compensate for wear of the parts. The brake-bar may also be adjusted to be raised higher or dropped lower by means of the bolt Q, connecting it to the dog 1?. This bolt is preferably fitted with double nuts Q, and by turning these nuts up or down and fastening them there the connection between the brake-bar L and dog P may be either shortened or lengthened, as desired.

The upper part of the carrier-frame A is fitted with bosses or studs-pins y, upon which the track-wheels D may be mounted in the usual manner, the boss being preferably made with a small hole through its center, into which a rivet 6 is inserted, with a washer 7 to hold the track-wheelD in place. \Vhen heavy work is required and there is great wear on the track-wheels, I use on opposite sides of the carrier truck-arms Z, which are fitted to goon the bosses Y in place of the wheels D and to be held in place by the rivet 6 and washer 7. On each end of the truck-arm Z is a boss y, the same as those on the carrierframe and set in the same plane, and upon these the track-wheels D are mounted. In this way the numberof track-wheels to support the carrier can be doubled and the wear on each greatly reduced.

Should there be more weight on one end of the carrier than on the other, the truck arms Z can be placed on the heavy end and double the number of trackwheels be used on that end, while single track-wheels maybe used on the light end in the usual manner, and the wheels on the truck-arms Z will be in the same plane as those mounted directly upon The truck-arms Z are also the purpose set forth.

made to oscillate slightly, so that the wheels mounted on its opposite ends will be free to accommodate itself to any unevenness of the track.
