ELEVATED CARRIER.

Specification of Letters Patent.

Patented Nov. 21, 1905.

Application filed April 27, 1905. Serial No. 257,622.

' such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to carriers, such as hay-forks and the like, traveling upon elevated guides, and more particularly to devices for use in connection therewith, and has for its object to provide a device by means of wh ch a carrier after discharging its load may be returned to position to receive another load.

Another object is to provide a device of this nature which will be extremely simple in arrangement and construction and which may thus be manufactured at a low figure and in which the parts will be unlikely to become deranged or broken.

Other objects and advantages will be apparent from the following description, and it will be understood that changes in the specific construction shown and described may be made within the scope of the claims and that any suitable materials may be used without departing from the spirit of the invention.

In the drawings forming a portion-of the specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a view showing a hay-fork with which the present invention is con nected. Fig. 2 is a side elevation of a returning device. Fig. 3 is a front elevation. Fig. 4 is a section on line 4 4 of Fig. 2. Fig. 5 is a detail perspective view of the drum-supporting parts. Fig. 6 is an elevation of the drums.

Referring now to the drawings, the present invention comprises a bracket 5, which is formed of a metallic bar bent at right angles to form a vertical portion 6 and horizontal ortion 7, the former being bolted against the ace of a suitable support 8 Adiagonal brace 9 connects the portions 6 and 7, as shown. Attached to the portion 7 at its free end there is a horizontal-exten ding metallic disk 1 0, having a circular series of perforations 1 1 therein adjacent to its periphery. The plate 10 has a central opening 12, which registers with an opening 13, formed in the portion 7 of the bracket 5, and these registering openings receive an upwardly-extending threaded pin 14, carried by the bight of an inverted-U- shaped yoke 15. A nut 16 is engaged with the pin 14 above the bracket, and the yoke is rotatable with respect to the bracket. The yoke is secured to the disk 10 by means of pins 17, engaged in the bight of the yoke and in the disk, and the disk is thus rotatable with the yoke.

Formed through the portion 7 of the bracket 5 there is an opening 18, which is disposed for successive registration with the openings of the series 11 when the disk and yoke are rotated, and in the registering perforations there may be engaged a pin 19 to hold the yoke and disk stationary.

Formed in the free ends of the legs of the yoke there are registering horizontal bearings 20, which receive a shaft 21, upon which there are mounted a larger and a smaller winding- drum 22 and 23, respectively. These drums include a wooden cylinder 24, which for substantially half its length is turned down to considerably less than its original size, as shown at 25, to form the core for the smaller drum 23, while the unturned-down portion forms the core 26 for the larger drum 22. A metallic disk 27 is secured against the outer face of the core 26 and projects beyond the periphery of its core, as shown, and

a similar disk 28, having a central opening 29, which receives the core of the smaller drum, is secured against the inner face of the core 26 and projects beyond the periphery thereof. Asmaller disk 29is secured against the end of the core and projects beyond the periphery thereof, as shown. These two drums lie between the spaced legs of the yoke 15 and are rotatable with the shaft 21.

A metallic yoke 30 is secured at the ends of its spaced legs to the legs of the yoke 15 at points below the top of the core of the drum 22, and this yoke 30 lieswith its bight 31 forwardly of the drum 22 and extends at right angles to the yoke 15. The bight 31 has an opening 32 therein provided with a wooden bushing 33, in which there is engaged a carrier-returning rope 34, which is attached to the drum 22 and is adapted to be wound thereupon, the yoke 30 thus forming aguide for the rope.

Secured to the lower ends of the spaced legs of the yoke 15 are the legs 34 of a yoke 35, which extends downwardly and rearwardly from the yoke 15 and lies with its bight 36 beyond the periphery of the drum 22, the portions of the legs 34 lying adjacent to the bight being bent downwardly at an angle, as shown at 37, to bring the bight 36 into horizontal position. The bight 36 has an opening 38 therein which is provided with a wooden bushing 39, and this bushing receives a cable 40, which is secured at one end to the drum 23 and is adapted to be wound thereupon. The other end of the rope 40 is attached to the bight 36 of the yoke 35, and between this end and the bushing 39 the cable is passed through pulleys 41, carried by a weight 50, the action of this weight being to hold the cable 40 normally unwound from the drum 23. The cable 40 and the rope 34 are wound upon their respective drums in opposite directions, so that when the cable is unwound from the drum 23 the rope 34 is wound upon the drum 22.

The rope 34 is attached to the carrier in connection with which the present invention is used in such a Way that when the carrier is moved with its load into position to discharge the latter the rope 34 is unwound from the drum 22, this unwinding revolving the drum 23, as will be readily understood, to wind the cable 40 thereupon. It will thus be apparent that when the carrier is released the weight will cause the cable 40 to unwind from the drum 23, winding the cable 34 upon the drum 22 and returning the carrier to its original position.

The legs 34: of the yoke 35 extend u wardly and forwardly of the legs of the yo e 15 and are secured at their ends to the legs of the yoke 30, these yokes thus bracing each other against movement with respect to the yoke 15, and it will be seen that the yoke 15 and the portions carried thereby may be revolved with respect to the bracket 5 to suit different conditions, the yoke 15 being held at the different points of its rotations by the pin 19. It is thus possible to move the drums to extend at difierent angles to the bracket, so that if it be necessary to secure the bracket to a support in such a position that the rope 34 does not lie in a plane with the bracket the drums may be shifted to bring them into the plane of the rope, thus insuring efiicient operation of the device.

The cylinder 24 is composed of a plurality of segmental blocks a, as shown in Fig. 6, which are tightly secured together.

What is claimed is 1. A device of the class described comprising a bracket a yoke connected with the bracket andincluding spaced legs, drums revolubly mounted between said legs and arranged for simultaneous rotation, cables engaged with the drums and adapted to be wound thereupon in opposite directions, a weight connected with one of the cables and arranged to hold the latter unwound from its drum and guides for the ropes said guides being secured to the yoke and to each other to brace each other against movement with respect to the yoke.

2. A device of the class described comprisin a yoke, drums revolubly mounted in the yore, cables engaged with the drums and guides for the cables said guides being secured to the yoke and to each other to brace each other against movement with respect to the yoke.

3. A device of the class described comprising a bracket, drums connected with the bracket for rotation in a vertical plane,cables engaged with the drums and adapted to be wound thereupon or unwound therefrom when the drums are rotated, said drums being also shiftable pivotally in a horizontal plane with respect to the bracket and means for holding the drums at different points of their horizontal pivotal movement.

In testimony whereof I afhx my signature in presence of two witnesses.
