HERBERT IIOVELL, OF BOSTON, MASSACHUSETTS.
CASTER.
SPECIFICATION forming part of Letters Patent No. 426,020, dated April 22, 1890.
Application filed January 27, 1890. Serial No. 338,243. (No model.)
To all whom, t may concern:
Be it known that I, HERBERT HOWELL, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in a Combined Caster and Stop; and I do hereby declare that thel following is a full, clear, and exactdescription of the same.
My invention consists in combining with' the caster-wheel and its bracket and sleeve a stop-bar held at its upper end to the end of the sleeve, extending through the same and through the bracket to bear upon the periphery of the wheel when pressure is applied to the article, and a spring surrounding the stopbar above the bracket to bear thereon and keep the stop and caster-wheel normally out of contact until the article is subjected to pressure.
In the accompanying drawings, Figure lis a view of the caster-wheel and support therefor, partly in sectionvith the stop combined directly therewith, the parts being in normal position to permit the free rolling of the wheel and the movement of the article. Eig. 2 is a similar View with the stop in action to prevent the movement of the Wheel.
The caster-wheel A, of any ordinary forni, is supported. in a bracket B, which has a hollow cylindrical shank l) and is provided with an opening l, passing through the cross-bar 2. This shank fits within a sleeve c and is adapted to slide therein, it being held normally down in the position of Fig. 1 by a spring 3 within the sleeve bearing upon the upper end of the hollow shank. The sleeve is flanged at a,
which flange bears upon the bottom of -the table or other leg when the device is applied to the article, as in Fig. 2.
The stop consists of the bar D, passing through the sleeve, the hollow shank, and the contact, thus holding the latter from turning.
It will be noticed that the stop-bar answers a twofold purpose-that of a stop and as a journal or spindle bar for the caster-bracket.
I claim as my invention* In combination, the caster-wheel with its bracket, a sleeve-socket adapted to be at tached to the article of furniture, a stop-bar held at its upper end to the end of the sleeve and extending through the same and through the bracket to bear upon the periphery of the wheel when pressure is applied to the article, and a spring surrounding the stop-bar above the bracket to bear upon said bracket to keep the stop and caster-wheel normally out of contact until pressure is applied to the artiele, substantially as described.
In testimony whereof I have signed my naine to this specification in the presence of two subscribing witnesses.
HERBERT I'lOlVELL.
