COMPLETE SPECIFICATION.
Improvements in Casters for Tables, Chairs, Sofas, and the like.
I, DAVID COOPER. of Maisondieu Lane, Market Street, Brechin, in the County
of Forfar, Scotland, Cabinetmaker and Furniture Dealer, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention relates to casters for tables, chairs, sofas and the like, its object
being to facilitate their transit.
The description of my improvements is assisted by two sheets of explanatory
drawings hereunto appended and hereinafter referred to.
Figures 1. and 2. (Sheet 1.) of the drawings are an external elevation and a plan
respectively of one modification of a caster;
Figure 3. is a section through A. A. (Figures 1. and 2);
Figure 4. a sectional plan at B. B. (Figure 3.);
Figures 5. and 6. an enlarged side elevation and a plan respectively of the
rollers, and Figures 7. 8. and 9. a section at C. C. (Figure 9.); a side elevation ;
and a plan respectively of the guide for the rollers, also drawn to a larger scale.
Figures 10. and 11. (Sheet 2.) are an outside elevation and a plan respectively
of a caster provided with a socket, and
Figures 12. to 15. other modifications of casters.
In these drawings the same reference letters and numerals are used to mark the
same or like parts, wherever they are repeated.
In carrying out my invention, according to the modification as illustrated on
Sheet 1. (Figures 1. to 9.), 16. is a screw which is brazed, soldered, or riveted
to the socket 19, it being employed to attach the caster to the leg of the article
which is to be mounted with same. The bracket 17. is free to turn about the
part 18. of such fixed screw 16. as a pivot. 19. is the socket in which the leg
terminates, the part 20. being a circular recess in which the rollers 21. move.
22. is a loose guide; in the recesses 23. of which the rollers 21. are retained.
Figures 10. and 11. show another modification, in which 24. is a socket for
receiving the leg, the pivot 18. being riveted thereto.
Figures 12. and 13. show the caster with a round plate 25. for attaching it to the
leg, and Figures 14. and 15. the plate 25. made rectangular.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
In casters:―
(1.) The employment of loose rollers 21. kept in position by a loose guide 22;
the combination working in a circular recess 20; the parts being combined and
arranged substantially as hereinbefore described, with reference to Figures 1. to 9.
of the accompanying drawings.
(2.) Constructing and combining the parts of the caster substantially as herein-
before described with reference to Figures 10. and 11. of the accompanying
drawings.
(3.) Constructing and combining the parts of the caster substantially as herein-
before described, with reference to Figures 12. and 13. of the accompanying
Irawings.
