J. H. STRONG.
SEWING-MACHINE CASTER.
Patented Apr'114,187 6.
UNITED TATES PATEN OFFICE.
JOSEPH H..STRONG, OF DES MOINES, IOWA.
IMPROVEMENT IN SEWING-MACHlNE CASTERS.
Specification forming part of Letters Patent No. 175,630, dated April 4, 1876; application filed To all whom it may concern.- 7
Be it known that I, JOSEPH H.- STRONG, of Des Moines, in the county of Polk and State of Iowa, have invented an Improved Caster for Sewing-Machines, of which the following is a specification My invention is an improvement of my caster patented March 17, 1874, No. 150,264. It consists in the manner of forming and combining a ring-formed brake with a caster and the foot of a stand, as hereinafter fully set forth.
Figure l of my drawing is a perspective view, illustrating my manner of arranging and combining a sewing-machine foot, a caster, and a ring-formed brake. Fig. 2 shows another mode of applying the same operating mechanism by means of a bracket.
A represents the foot of a stand. .It has a vertical bore in its center, as indicated by broken lines. I) is a horizontal slot or mortise, intersecting the bore in the center of the foot. 0 is the spindle or shank of the wheel-bearer B. d is a groove in the shank 0, corresponding in position with the slot b in the foot A.
f is an open ended loop or staple, passed through the slot bin the foot A, and thegroove d in the shank c, to form a bearing for the rotating shank c, and to retain the shank in the bore of the foot.
I am aware that a caster has been combined with the foot of a stand in a similar manner; but I consider that my ring-formed brake, in combination with the otherelements, is new and advantageous.
January 3, 1876.
Fig. 2 is a perspective view, illustrating my improved manner of applying and operating a ring-formed brake.
G is a ring-formed brake, in the shape of a conical sleeve, designed to pass over the foot of a stand, or a substitute for a foot carried by an attachment or bracket, D. g is an inclined plane in the top edge of the sleeve D. h is a corresponding inclined plane on the foot or bracket. Similar inclines are formed directly opposite to keep the sleeve and ringformed brake O in balance. mm represent projections on the sleeve 0, designed as handles or levers for turning the sleeve. By turning the sleeve 0 to the left, the fixed and inverted inclined planes h on the foot will engage the inclined planes 1 in the top of the sleeve, and press its base and ring-formed brake upon the caster-wheel and lock it. A reverse movement of the sleeve will free the wheel.
I claim as my invention 1. The caster-pintle 0, having the groove 01, the foot or socket A, having the slot b, the ring-formed brake O, and the securing-loop f, all arranged and combined substantially as and for the purposes shown and described.
2. The ring-formed brake and sleeve 0, having the inclined planes 9, in combination with a foot or bracket, D, having inclined planes h, and a caster-Wheel, substantially as and for the purposesshown and described.
JOSEPH H. STRONG.
