UNITED STATES PATENT OFFICE.
HIRAM S. D'OOLITTLE, OF KORTRIGHT, NEW YORK.
||v| PRovEMENT IN HORSE-RA'KES.
Specification forming part of Letters Patent No. 4,708, dated August 22., 1846.
` a full, clear, and exact description of the construction and operation of the same, reference `being had to lthe accompanying drawings,
making part of this specification, in which* Figure 1 is an isometrical view of one of my rakes, and Figs. 2, 3, 4, and ,5, are detached parts. Y
The same letters refer to the same parts in all the iigures.
a a a is the axis, of wood, into which the teeth bA b b, Src., are set.
The mode of inserting and forming the teeth is as follows: A row of holes having` been bored quite through the axis a, in a straight line from end to end, at a distance apart corresponding to the interval required between the teeth, a straight piece of stout iron wire, of sufficient length to form two teeth, is entered at each hole and drawn through in such manner as to haver equal portions projecting upon each side of the axis. These two portions are then bent in opposite directions, entirely around the axis, thus forming a ring'y near the root of the tooth, which ring embraces the axis, as shown at c c c, 8vo., Fig. l. The remaining straight portions of wire are theny bent into the desired form of tooth. The form which I employ is shown in the drawings. The axis is inclosed in a frame consisting of the side pieces, d d,
and the cross-pieces e e. The shafts f f f f, with their braces g g, are bolted to the crosspieces c e, and extend backward over the axle,
'being secured thereto, as shown in Fig. 3,
where f is a portion of one of the shafts, a the axle, and h a part of one of the handles. A
staple, i c', embraces the axle, (being received into a circular groove, which is made around this'latterto prevent the lateral motion thereof,) and passes up through the end of the shafts and the foot of the handle. Two screw-nuts, j j, secure the whole.
To prevent the screwing up the nuts, from ,would impede its revolution,two shoulders, lc k,
are formed upon the legs of the staple, which resistr the pull of the screw by acting upon the under side of the shafts. To prevent the revolution of the axle and maintain the teeth in the proper position, an iron ring, Z, is xed uponthe center of the former. It has a small stud, m m, projecting from both its upper and under side. This stud is received in a slot, o, made in the spring n. The forward end of this spring-is firmly screwed to the cross-piece e.
It is evident that while either stud is embraced by the slot o the axle must be stationary. By pressing the foot, however, upon the hinder end of the spring n, the stud is disengaged, and the draft ofthe horse causes the axle to partially revolve. To continue the revolution until the opposite stud falls intothe slot, and thus bring the other set of teeth into an acting position, I employ supplementary teeth .fr x, Ste. (Exhibitedby red lines in Fig. 2.) I shall usually insert these teeth in two sets, as shown in Fig. 1, forming two spiders, the arms of which are arranged'at intervals of sixty degrees. It is evident that during the revolution ofthe axle the points of these supplementaryteeth will successively come in contact with the ground, and serve to support the machine and continue the revolution.
My apparatus is both simple and light, and does not require, as the common horse-rake does, to be lifted in orderto revolve the teeth.
What I claim as my invention, and desire to secure by Letters Patent, is-
l. lCombining with the revolving axle the ring l, with its studs m m, together with the spring n, containing a slot, o, to receive and retain'the studs successively, and thus maintain theteeth in the proper position.
2. Inserting the supplementary teeth forming the spiders, operating'in the manner and for the' purpose herein described.
