HAAKON P. HANSON, OF ALBERT LEA, MINNESOTA.

HAY-CARRIER.

To all whom it may concern:

Belt known that I, HAAKQN P. IIANSON, a c tizen of the United States, residing at Albert Lea, in the county of Freeborn and State of Minnesota, have invented a new and useful Hay-Carrier, of which the following is aspecification.

This invention has reference to hay carriers, and its object is to simplify the construction of the hay carrier and to permit the lifting pulleys to be hoisted closer to the track than heretofore while the weight of the load is centralized, the whole structure permitting the employment of a very simple and efficient form of locking device.

In accordance with the present invention the lifting strand, which may be partly of rope and partly of chain, is caused to travel about a sheave having its axis of rotation diagonal to the hay carrier track, thus doing away with guides and shelves hereto fore employed, so that the lifting strand or rope is not crowded. Furthermore, the employment of a special locking device in connection with the arrangement of the sheave over which the rope travels permits the lifting pulleys to be hoisted closer to the track and to be located transversely of the track and centrally thereto, thus equalizing the weight on the track.

The locklng device permits the use ot chainwhere heretofore rope has been employed, and consequently wear is correspondingly reduced. The locking device utilizes a rope clamp, connecting the rope and chain together, as a keeper for one member of the locking device with a latch structure and a fixed stop on the track coacting to lock and release the lifting pulley structure automatically.

The invention will be best understood rom a consideration of the following detailed description, taken in connection with the accompanying drawings, forming part of this specification, with the further understanding that while the d 'awings show a practical form of the invention, the latter is not confined to strict conformity with the showing of the drawings, but may be changed and modified, so long as such changes and modifications come within the scope of the appended claims.

In the drawings Figure 1 is an end elevation of the carwith some parts broken away, the carriertrack being 'shown' m cross section, I

Specification of Letters Patent.

Patented Apr. 2, 1918.

Fig. 2 is a side elevation of a portion of the carrier with some parts broken away and in section, and showing the locking member in position just prior to engaging the lifting strand at the rope clamp.

Fig. 3 is a view of the locking mechanism similar to the showing of Fig. 2, but with the-parts in the locking position.

Fig. -l is a perspective view of the lock member for engaging the rope clamp.

Referring to the drawings, there is shown a track 1 and a hay carrier frame 2, both of which may, in the main, be of ordinary form and need no particularly specific description. Mounted on the carrier frame 2 is a sheave 3 of a character to permit the passage of a rope -labout it. The sheave 3 is mounted upon a pintle 5 carried by the frame 2 and arranged diagonal to the directionof travel of the carrier upon the track 1, the angle of diagonal displacement being about forty-live degrees more or less. Mounted in an offset portion (3 of the frame is a guiding sheave 7 about which the rope t is carried, so that the rope after leaving the sheave 7 may extend lengthwise of the track 1., while between the sheaves 3 and 7 the rope has the same diagonal relation to the track as the sheave 3.

One end of the rope -l is connected by means of a coupling 8 to one end of a chain 9, the other end of which is connected to a pin. 1.0 or other part of the carrier frame .3 at a point opposite to that side of the sheave 3 about which the rope -'l: passes.

The chain 9 is of such length that it sustains the compres ion pulleys 11 with the load connected to the hoolzs 12 on the frames 13 car he pulleys 11.

Secured in the frame 2 adjacent to the sheave 3 is a journal pin 1% upon which is mounted a rocker shaft 15 formed at one end with a rocker arm 16 extending in a direction substantially at right angles to the axis of rocking and at the other'end formed with a lug 17 also extending at substantially right angles to the axis of rocking and on the opposite side of said axis to the arm 16. The

.lu 17 is provided with a shoulder 18 and apart-and the spacing of one pair of fingers from the other being somewhat greater than the length of the rope coupling 8, which, as shown in the drawings, is in the form of a metal cage having

ends

23, 24 adapted to lodge between the pairs of fingers 21, 22, as will hereinafter appear.

Fast to the track 1 and depending therefrom is a stop

yoke having legs

26, 27 spaced apart in the direction of the length of the track.

Mounted in the frame 2 is a rocker 28 having a nose portion 29 and an ad aCent surface 30 curved correspondingly to the

surfaces

19 and 20 respectively. The rocker 28, which is in the nature of a latch member has a yoke portion 31 with

legs

32, 33 adapted to engage the

legs

26 and 27 1n a manner to-be described. When the load is being lifted, and has about reached the limit of elevation, the parts may be assumed to be in the position shown in Fig. 2. Under these circumstances, the rocker member is so positioned that the clamp or connector 8 may rise by the fingers 22 which are then out of the path of the connector 8 and ultimately engage the fingers 21, the rope 4 1n the meantime passing between the fingers 21.

At the same time the leg 32 of the latch member 28 is lodged between the

legs

26 and 27 of the fixed stop 25, while the nose 29 of the latch member 28 is resting upon the surface 19 of the lug 17 and the weight of the latch member 28 holds the rocker 15 in the position stated. The continued rising of the connector 8 causes the end 23 thereof to engage the fingers 21 and as the point of engagement is to one side of the axis of rocking of the rocker 1.5, the latter is turned about its axis causing the fingers 22 to ride into underriding relation to the end 2 1 of the connector 8 until further movement in that direction is stopped by engagement of the arm 16 with the chain 9.. The rocking movement of ther cker 15 causesthe lug 17 to move from under the nose 26 until the latter is no longer supported by the lug 17 *and the rocker 28 gravitates toward the shoulder 18, the curved surface 30 then moving along the curved surface 20 and holding the rocker member against movementin a direction to carry the fingers 22 away from the underriding relation to the connector 8. The fall of the rocker or latch member 28 carries itsleg 32 from between the

legs

26 and 27 of the fixed stop member 25. These movements are all performed automatically and in quick order, so that the connector 8 becomes lockedbetween and sustained'by the fingers 21 and 22 of the arm 16 and the latch member 28 is released from the stop member 25, whereupon the frame 2 is drawn along the track 1 by the continued pull upon the rope When the structure is returned to the stop member 25, the leg 33 of the latch member 28 is then in the elevated position with the leg 27 of the stop in its path. The movement of the carrier frame 2 then causes the rocking movement of the latch member 28 in a direction to lift the nose 29 away from the shoulder 18 until finally the nose 29 is above the'end 19 of the lug 17 and the weight of the parts sustained by the chain 9 is suflicient to move the rocker shaft 15 and arm 16 to an extent withdrawing the fingers 22 from underriding relation to the connector 8 whereupon the latter may drop with the rope at moving in the appropriate direction for the purpose.

The structure shown in the drawings is of extreme simplicity requiring but the presence of the diagonally mounted sheave 3 and.

, the roller 7 to bring the compression pulleys crosswise of the track and eliminating guides and sheaves heretofore employed for the purpose. Moreover, the arrangement permits the lifting of the load to a higher elevation with respect to the track than heretofore and also permits the employment of a locking device of extreme simplicity and great eiiiciency. The use of the connector 8 permits the employment of chain where heretofore rope has been used, thus greatly reducing the liability of wear and offering stronger resistance to the effects of strains than is ofl'ered by rope, especially fiber rope. The employment of the connector 8 permits the use of theholding member consisting of the rockershaft 15, lug 17 and arm 16, with its fingers 21and 22, and of the latch 28 with the fixed operating stop 25.

It will be understood that the connector 8 may be replaced by any suitable device capable of serving the same purpose so far as the locking structures are concerned.
