' Leners' Patent Nb. 103,165, dated May 17,1870.

`IMPRQ'VEMENT IN 'FURNITURE-CASTERS.

The Schedule referred to ixx` these Letters -Patent and making part of the same.

,Be it known that -I,FRE"DERIc G. Fono, of the city, county, andiState of New Yorkhave invented a new and useful Improvement. in Casters, of which 1 y the following is a full, clean; and exact description,

reference being had to` the accompanying drawing forming part of this specification, and in which- `Figure 'l represents a side view of myimproved caster as adapted to fiat work, and Figure 2, a plan' of the same'. Figure 3 is a sectional elevation of a similar style of caster under a modified construction ofit," and' Figure 4, a plan thereof.- ,Similar letters of reference indicate corresponding parts.v v

',Myinventiou consists in certain novelties of con.- struction, which cheapen the production and add to the efficiency of the caster; also facilitateithe attachment of the same to furniture or articles'of various kinds, substantially as hereinafter described.

Referring, 1n the first instance, to figs. l` and Ziof the drawing, which represent a style of caster applica-- ble to dat or straight work, A is the bottom plate, that butts up or` bears against the under surface or -lower end-of the leg or other portion of the piece of furniture, and which maybe made to enter the latter :l by means of teethor prongsa a.

Projecting upward from the plate A is a bearing, b, that is received within a recess made in the wood B,

l which is the body or` part that carries the caster.

Fitted to work snugly but 4freely within and up through the plate A and bearing b, is the pivot-pin or screw d, on which the wheel-bracket or armfDof the caster swings. y

This pivot-pin may either be made with a screwthread on its yupper projecting end, to screw into the wood, or it may be left plain, as desired.

O is a sideplate, connected or cast in one piece with the bearing lr and plateA, and serving to tit ou or into `the side ofthe wood,\to hold the Acaster to the latter, and which may be secured by screws passing through holes c c.

` Said side plate is formed with vertically guiding and whole caster morge securelyr to the wood, and whereby fastening screws may, if desired, be dispensed with.

' The bearing b I prefer to cut away-or reduce interinediately of' its length, as at c, which not only economises metal, but enables me to simultaneously Awork two or-op'posite drills in-boring out or dressingv the bearing for receptiouof. the pivot-pin or screw'd, and,

-infit-ting up a large number of casters, results in an important saving of time. y

Figs- 3 and 4 show substantially a similar construc-l tion of. caster, but here the edges of the side plate C are serrated, as at e' e', which causes said guiding and holding edges to more readily cut their way and pack or lock themselves in the wood against dropping out ofthe caster. v

To hold the several parts of the castertogethcr, and pivot-pin r screw dto 'its place, I form an annular groove in said pin or screw at a suitable distance above its head, which latter establishes 'the nnderlock, and

spring a strip -or plate, s, over said pin `or screw, into such annular groove that is arranged where the upper lock is required, and which such spring plate serves to establisln by bearing down on or over the plate or frame portion of the cast-er.

That is here claimed, and desired to be secured by LettersPatent, `isy v A furniture cast-er, constructed with the bearingb to the `pivot-pin or screw d, and the slide plate C, formed ivith vertical' guiding and holding-strips e on its edges, whether said socket is inserted in the body of'thewood or otherwise, in combination with the wheel and bracket D, substantially as specified.
