TIMOTHY I. CAMPBELL, OF EAST KOY, NEW YORK, ASSIGNOR TO CAMP- BELL BROTHERS, SAME PLACE.
IM PROVEMENT IN HAND-:RAKES.
Specification forming part ofLet-ters Patent No. 197,825, dated December 4,1877; application filed June 22, 1877.
To all whom it may concern:
Be it known that I, TIMOTHY- I. CAMPBELL, of East Koy, in the county of WVyoming and State of New York, have invented certain new and useful Improvements in H and-Rakes; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification,
the cost of the rake, makes it more durable and proportionately valuable.
The socket which I employ in carrying out my invention is made of castiron, and of the shape shown in section in Fig. 2 of the drawings-that is, consisting of a sleeve, A, conical or tapering in shape, so as to correspond with the taper of the lower end of the rakehandle D, as shown in Fig. 2. Near its lower end the sleeve A has two laterally-projecting wings, b b, forming a plate, B, which is cast in one piece with the sleeve, and completes the socket.
The lower end of the sleeve, it will be observed, projects below the plate, as shown at a. In adjusting the socket upon a rake-head this portion is fitted into a recess, 0, forming the upper end of the perforation d, which is made in the rake-head O, to receive the handle. The socket is then secured in position upon the rake-head by nails or screws 0 e, the wings b I) having perforations for this purpose. Finally, the handle is driven in firmly and secured with a nail through the both braced and strengthened, the additional weight is trifling, and the cost of making the improvement is but slight.
Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- The combination of the rake-head G, having recess 0, with the tapering rake-handle D and brace or fastening B, consisting of taperin g socket-piece A, having laterally-pro ecting wings I) b and annular shoulder a, substantially as described, for the purpose herein shown and specified.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
I TIMOTHY I. CAMPBELL.
