FELLY-TIGHTENER.

SPECIFICATION forming part of Letters Patent No. 270,413, dated January 9, 1883.

Application filed May 2, 1882.

(No model.)

.act descriptioni The object of myinvention is to provide means for tightening or taking up the play in fellies of wheels in cases where it is not convenient or desirable to do so by having the tire reset.

My invention consists in a novel construction, arrangement, and combination of a rightan d-left-threaded screw, two internally-threaded bars, two pairs of clamping-jaws, and two pairs of lastening-bars, together with certain details connected therewith, whereby provision is madefortighteningiellies, eitherby drawing or pushing, without removing the tire, and, if necessary, without removing the load which 'may be upon a wagon, as hereinafter more particularly described.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side view of my invention in position for use. Fig. 2 is a longitudinal sectional view. Figs. 3, 4, and oaredetail views.

A reprcsentsaright-and-lettthreaded screw with an angular head, a, midway of its length.

B B are two bars, which are provided respectively with righthand and left hand threads. The bars may be of iron and have the threads formed in them, or they may be of wood simply bored and provided with straps D D,-embracing two or more sides, and having the threads formed in the portions which are at the inner ends of the bars, or may be made of any suitable form or material.

E represents a platehavingitsinner surface provided with serrations; or itsinner surface may be provided with a groove, 6, or recess to fit over the spoke, and a serrated portion, 0, at one end to clasp upon the felly. It-is further provided with a slotted hole at the other end to allow for adjustment with the bars B andthe wheel. Two of these plates are at tached to the outer end of each bar B by a bolt-,f, passing through them and through the bar and fastened by a nut, g, and thus form a" pair of clamping-jaws.

H represents a clampingbar having boltholes at its ends for the reception of bolts 7L and 2'. Two of these. bars are attached to each .bar B, between'the plate E and the inner end of upon the felly when the tightener is to be used to draw the felli-es together, as shown in Fig. 1'. The outer end of each bar B, between the clamping-jaws E,is provided with a cushion, K, which may be of chamois skin, cloth, felt, rubber, or any other suitable material.

The operation of my invention is as follows: The apparatus is placed between two spokes of a wheel,- near the felly, with the cushioned ends of the bars bearing against the spokes. The clamping-jaws E are then pressed closely against the two opposite sides of the folly and secured by tightening the nuts 1 on the boltsf. The bars H are then placed one on each side of the folly and tire and secured by the bolts h and t and their fastening-nuts, the bolts 2' being passed through the outer endsof the bars outside of the tire, or,'if it is intended to take up the play in the fellies, by drawing the follies together the bars H are placed one on each side of the clam ping-jaws E and secured by-tlie boltshand'i,andtheendsofthejaWsEthusheld firmly tothe felly by tightening the bolts. The fellies are tightened by turning the screw A in one direction or the other. If they are to be drawn toward each other, the screw is turned so as to screw both of the threads into their respective bars, and the spaces between the fellies and the tire arefilled by thin pieces of any-suitable material put in with lead, paint, or any cementing substance to hold them in place. This is to be done evenly around the wheel, so

as not to throw the wheel out of shape. If

they are to be pushed outward away from each other and against the tire, the screw is turned in the opposite direction, so as to unscrew the threads i'rom their respective bars,

make the ends ofthe fellies bear solidly against and the joints between the ends of the fellics are filled by pieces of any suitable material to each other.

The screw A may be turned by means of an ordinary wrench applied to the head a, or the device shown in Fi 3 may be employed. This consists of a lever, L, having its fulcrum on the screw A, and carrying a pawl, M, engaging with a ratchetwheel, P, carried by the head a, as shown in Fi 3.

The advantages of myinvention are: it is cheap and simple in construction and is strong and durable. It can be used to tighten the t'ellies by either drawing or pushing. The cushions K prevent the marring of the painted surtace of the spokes and fellies, and the serrated clamping-jaws take hold of the wood of the i'ellies, so as not to injure the same. The fastening-bars 11 hold the apparatus securely in place and prevent it from slipping in either direction. It can be used by any one, and can he used to tighten a wheel in cases where there is not time to have the tire reset, and can be used when a load is on a wagon to save n11- loading' the same.

Having thus described my invention, Iclaiiu as new and desire to secure by Letters Patent 1. Afelly tightenerconsistingofaright-andleft-threaded screw, two interually-threaded bars, two pairs of serrated clamping jaws, and two pairs of fastening or clamping bars, H, I
