LEWIS F. FALES, OF VALPOLE, MASSACHUSETTS.

CHAFE-IRON.

SPECIFICATION forming part of Letters Patent No. 617,483, dated January 10, 1899.

Application led November 18, 1898. Serial No. 696,791. (No model.)

To ail whom t may concern;

Be it known that I, Lnwrs F. FALEs, a citizen of the United States, residing at Walpole, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Chafe-Irons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

My invention relates to chafe-irons'for vehicles, and particularly to a roller chafe-iron.

The object of my invention is to produce a roller chafe-iron in which the roller shall be efficiently supported in the framework and by means Which will prevent rattling of the same as a result of wearing of the parts in use.

To this end, therefore, my invention consists in a roller chafe-iron hereinafter to be described, and more particularly set forth in the claims.

In the drawings illustrating the preferred form of my invention, Figure 1 is a plan view of the iron with a portion 'cut away, showing the construction of the support for the roller; and Fig. 2 is an end view of the same.

Like reference characters refer to like parts throughout.

1 indicates the supporting-frame for the roller 2, which is mounted in bosses 3, provided onthe ends of the frame. The body of the frame is adapted to be secured to the vehicle-body in any suitable manner.

The roller 2 is provided with cylindrical longitudinal holes 4 in its ends, centrally disposed with relation to the surface of the roller. These holes 4 are adapted to receive pins 5,

which project into the holes from the bosses. -In order to prevent the 'pins from rattling and rotating in the bosses, they are taperin gly flattened on one side near their outer end, as at 6, and are received in a correspondingly-shaped hole in the boss. By means presently to be vdescribed the pins 5 are pressed outwardly,

and as a result the tapered portion ofthe pin is pressed into the hole in the boss, so that play between the two is effectively prevented. The roller rotates on the pins, and any suitable means may be provided to press the pins outwardly. The preferred means for pressing the pins outwardly consists of a spiral spring 7 in the hole 4, which normally presses outward toward the pin 5. In order to prevent a rattling of the pin 5 in the hole 4 of the roller, the inner en d of the pin 5 is out oif on a diagonal plane, and a wedge 8, which consists of a short section of a cylinder cut olf on its outer end on a diagonal plane corresponding to the inner end of the pin 5. The

course of time rattle, I preferl to interpose between the spring 7 and the wedge 8 awasher 9, which by reason of the friction of the spring against it will be constrained to rotate with4 the roller. Thus the roller rotates on the pin 5 and wedge l8 without wearing off the end of the spring. To this end I preferably provide the outer side of the washer with a centrallydisposed projection 10, which tends to reduce the friction .between the washer 9 and the wedge 8 to a smaller amount than that between the washer 9 and the spring 7. The spring will preferably have an outside diameter very closely approximating the diameter of the hole 4, so that the spring shall not rattle therein. In like manner the washer 9 will also correspond closely to the size of the hole 4 for the same reason.

In assembling the chafe-iron a spring is placed in the bottom of one of the holes, and upon it is placed the washer, followed in turn by the wedge and by the pin. `Then holding the pin lightly in position with one hand the roller may be turned end for end and the cor- IOO and they will be pressed entirely out to the end, thus being brought to their operative positions. The device then is ready for application to the vehicle.

Among many advantages of this construction there may prominently be mentioned these: that the device will not rattle and that the roller may readily be removed from the frame during paintin g or if for any reason the device should become clogged.

Having thus described my invention, I claim as new and desire to secure by Letters Patent of the United Statesl. In a cha'feiron, the combination with a frame, of a roller provided with holes in its ends, pins supported in the frame and pro j eeted into the holes in the ends of the roller, and means to press the roller against the sides of the pins, substantially as described.

2. In a chafe-iron, the combination with a frame provided With taperingholes, of a roller provided with holes in its ends, tapering pins supported in said tapering holes in the frame and projected into the holes in the roller, and means to press the roller against the sides of the pins, substantially as described.

3. In a chate-iron, the combination with a frame, of a roller provided With holes in its ends, of pins supported in the frame and projeeted into the holes in the roller, Wedges to press'the roller against the sides of the pins and springs to press the Wedges against the roller, substantially as described.

AI. In a chate-iron, the combination with a frame, of a roller provided with holes in its ends, stationary pins supported in the frame and projected into the holes of the roller, means to press theroller against the sides of the pins, a spring to aetuate said means and a Washer interposed between the said spring and the said means, substantially as described.

5. In a chate-iron, the combination With a frame, of a roller provided with holes in its ends, pins supported in the frame and projected into the holes in the roller1 the inner ends of the said pins being cut on diagonal planes, correspondingly-shaped Wedges to press the roller against the sides of the pins and means to press the Wedges against the roller, substantially as described.

In testimony Whereol` I alx my signature in presence of two Witnesses.
