HORSE-',RAKE.'

SPECIFICATION formingvpart of Letters Patent No. 352,884, dated November 16, 188.6.`

Application filed July 17, 1885.

To all whom it may @o7/90ern,.- f

Be it known that I, SHERMAN R. NYE, of Chicopee Falls, in the county of Hampden and State of Massachusetts, have invented certain n ew and useful Improvements in Horse-Rakes, of which the following is a specication.

A This invention has for its object to provide a simple, strong, and effective device for supporting a metal tooth and its holding-down spring on the head or axle of a horse hay-rake; and it consists in the improved holder, which I will now proceed to describe and claim, the accompanying drawings forming a part of this speciiication.

Figure l represents a side elevation of my .improved holder and a partof the tooth. Fig. 2 represents a top view of the same. Fig. 3

represents a section on line x x, Fig. 2. Fig.V

width of the ear, so that the margin of the earforms a shoulder around the boss.

6 represents the tooth, which,.as usual, is made of aI curved metal rod, the upper end of which is bent into a hook or loop which partially surrounds the boss 4. The projection 5 on said boss stands between th'e body of the tooth and the end of said loop, as shown in Fig. 3, and its opposite sides constitute the stops which limit the oscillating movements of the tooth on the boss, the projection 5 being of such width relatively to the space between the body of the tooth and thev end of the hook thereon that the tooth is permitted a limited oscillation on the boss, and is thus permitted to' rise and fall at its'lower end as the inequalities of the surface of the ground require. 'Ihe ear 3 is perforated to receive a bolt, c, and on said bolt, by the side of the boss 4, is placed a collar, d, which is clampedsecurely against the boss by the bolt c.. The diameter of the collar dis greater than that of the boss, so that its inner end forms a shoulder, which bears against Serial No. 171,867. (No model.)

the side of the hook of the tooth and keeps the latter in place laterally against the ear 3.

e represents the holding-down spring of the tooth. Said spring is coiled upon thekcollar d,

and is hooked at one end. to engage with and' press'downwardly upon the tooth, its other end bearing upon a rib, z', on the base. Said rib has a notch at i,which receives the end of the spring and prevents the latter from slipping sidewise. rIhe rib 't' is extended upwardly on the ear 3, and bears against the tooth to prevent it from slipping off from the boss in the direction of the length oi' the tooth. The collar d is preferably larger at its outer than at its inner end, so that the spring will not have a tendency to work off from its outer end. The portion of the bolt c that is contained in the collar d, and the orifice in the collar that receives the bolt, are preferably square, so that the collar cannot rotate on the bolt.

It will be seen that the described devices are extremely simply and can be put together and applied to the rake-head with comparatively little time and labor. lAs there is but one ear to receive a bolt-hole, the amount of drilling required is reduced to the minimum, and the spring can be more-readilyapplied -and removed than it ,could be if placed between two ears. It is obvious that the collar d may be an enlargement made in one piece with the loolt,

instead of being in a separate piece.

I claimj l. The combination of the holder .or bracket composed of the base 2, the single ear 3, formed thereon, the cylindrical boss 4, formed on and proj ectinglaterally from the ear 3, the margin of said ear projecting outside of said boss, and forming witlr the body of the ear'a shoulder around the boss, the collar d, detachably secured to the ear, the inner end of saidI collar forming a shoulder surrounding the boss, the

tooth having a hook portion partly surrounding the boss and confined between the itwo shoulderssurrounding thelatter,andthespri ng coiled upon the collar and engaged at its ends,

respectively, with the base and tooth, as set` 2. The holder or bracketcomposed of the base 2, the single ear 3, the cylindrical boss 4, projecting laterally from the ear inside of the margin thereof,and provided with a projec- IOO tion, 5, a shouldered collar, d, detachably secured to the boss 4, the projection 5 being 1ocated in the space between the ear 3 and collar cl, the tooth having the hook portion bent to form a part of a circle and confined on the boss 4 between the collar d and ear 3, the arrangement being such that the tooth can oscillate on the boss, its oscillations being limited by the projection 5, and the spring e, coiled upon the collar and engaged at its ends, respectively, with the base and tooth, as set forth. l

3. The holder or bracket composed of the base2, having the notched rib z', the single ear 3, the cylindrical boss 4, projecting laterally from the ear inside of the margin thereof, and provided with a projection, 5, a shouldered collar, d, detacheyy secured to the boss 4, the

. projection 5 being located in the space betweeh `to this specification,in the presence oftwo subscribing witnesses, this 24th day of J une, 1885.
