IMPROVEMENT IN HORSE HAY-FORKS. n

Be it known that I, FRED CULVER, of the borough ot Elkland, in the county of Tioga, and State of Pennsylvania,` have invented a. new and useful Improvement in Hay-Forks; and I do hereby declare that the following `is a. full, clear, and exact description of the construction and operation of the same, reference being had to drawing No. l. and its accompaniment, as follows, to wit:

Figure 1 is an outside view of entire article.

Figure 2 is an inside view of same.

Figure 3 is machinery inside of casev Being` the three components of entire machinery, as will more fully Aappear by annexed schedule.

A, case; B, handle, fulerum, a-nd pulley; C, upright shaft; D D, arms, as operated upon by upright shaft; a a, slots for extending or returning arms; B B, rivets on shaft, which pass through the slots in arms; C, rivet through arms, connecting sameto case; D D, apertures in case for extension or contraction of hooks 01' barbs; FF, handle attached to upright shaft, connected by rope with pulley. j

The case A is nearly fiat, slightly convex` about ythree inches in width, and about three "feet long, within which the upright shaft and arms 'are worked from pulley in the handle, the arms D D being connected together by a rivet passing through the case A, operating` as a fulcrum to said arms, and same being extended or closed by means of slots marked/L a, which throw them from the case ready for use; and by reversing the power they are shut within the case, thereby relieving themselves of'tbeir load, being governed and'controlled by a cord` or rope attached to handle F F on up'right'shaf't, and'running over pulley. It is contemplated, it' found necessary, to attach n spring and catch, to hold the arms und barbs in` position when extended for receiving the load, to be governedby the-rope attached to pulley and shaft. I The arms D D may each have an additional hook or barb, which would extend through the case a few inches above the other barbs. The whole may be made of' iron or steel. f v y The followingfare claimedto be new inventions und distinct improvements from anything heretofore introduced to the public notice: i f i y lThe combination of upright shaft C, rivets or pins B B, arms D D, with slots a a at their upper end, and barbs at their lower end, the whole arranged substantially as and for the purpose specified.
