(Application filed Mar. 19. 1898.,

(N0 Model.)




SPECIFICATION forming part of Letters Patent No. 610,309, dated September 6, 1898.

Application filed March 19, 1898. Serial No. 674,472. (No model.)

To all whom it may concern.-

Be it known that I, EDMOND B. SLATER, a citizen of the United States, residing at Meriden, in the county of New Haven and State of'Connecticut, have invented a new and useful Improvement in Furniture-Casters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,forming a part of this specification, in explaining its nature.

The invention relates especially to the horn of a furniture-caster; and it consists in providing a peculiar-shaped blank of fiat metal and the horn made therefrom.

Referring to the drawings, Figure 1 is a view in plan of the blank. Fig. 2 is a view in perspective of the horn made from the blank. Fig. 3 is also aview in perspective of the said horn turnedfrom the position represented in Fig. 2. Fig. 4 is a View in side elevation of the complete caster. Fig. 5 is a View, partly in elevation and partlyin vertical section, of the complete caster.

The blank A from which the horn of the caster is formed is punched or otherwise made from sheet metal, and it has integrally-connected sectionsa a, which form the arms of the complete horn-sections a a which are adapted to form the upper and lower pintlebearings, and the connecting-section a, unit ing the arm-forming sections and the two bearing-forming sections. The arm-forming sec tions preferably are curved from the end of the connecting-section a and have at their outer ends the holes a The arm-forming sections also have at their. upper ends the shoulders at. The pintle-bearing sections a a each have a pintle-hole a and each preferably has the curved back a on each side of its juncture with the cross-bar a the shoulder a", and the straight edge a although the form of this edge is immaterial. The blank thus shaped or similarlyshaped is formed at one operation of a punch and die, and it is then submitted to a further forming operation whereby it is converted into the complete horn and whereby the connecting-section a is curved or bent to form a side wall I) of the complete horn B and the arm-forming sections a a brought parallel with each other to form the arms Z) of the horn and to bring the holes a in line with each other, the arms being separated from each other by a space sufficient to receive the caster-roll C and the holes a acting to receive the cross-pin c, which secures the caster to the horn-arms.

The pintle-bearing sections a a are bent to a right angle to the wall I) and form the horizontal supports 1) b for the pintle D, which are separated from each other by the Width of the Wall. They are turned in the same direction, so that the pintle holes a are brought into line with each other, and their curved edges rest upon or bear against the top and bottom edges of the said wall I), while their shoulders 67, a interlock with the shoulders a at the upper ends of the arms and the intermediate section between the arms and form spacing or distance pieces which prevent the further closing of the arms toward each other.

The pintle is attached to the supports 5 b in any of the usual ways. I have represented a conventional one in which the pintle is represented as having a head d at its lower end, beneath the lower support b and awasher d, which is pressed or otherwise united to the pintle and is carried by it immediately above the upper support b The advantages of the invention arise from the simplicity of the construction,its strength, and the cheapness with which it can be made, as but two operations are necessary for forming the complete horn. I do not wish to be understood as confining myself to the especial form of blank shown or to the particular shape of horn obtained from it, as there may be various changes in these forms and shapes which will not modify the principle of the invention.

Having thus fullydescribed myinvention, I claim and desire to secure by Letters Patent of the United States- I 1. In a blank for forming horns, the armforming sections a, a, having the holes a and shoulders afithe pintle-forming supports 60 ,11 having the shoulders a and the holes a and the integral connection a 2. As an improved article of manufacture the caster herein described, the same'comprising a horn B formed from a one-piece flat metal blank having a vertical rear wall Z), forwardextending parallel roll-supporting arms I), fiat pintle-supporting plates b 13 extending forward from the upper and lower edges of said back wall I), the upper of which has both sides extended upon said arms I) and is supported thereby as well as by the back, the pintle D carried by said supporting-plates b b and the caster-roll attached by a pin to said arms.

3. 111 a caster-horn a vertical wall, roll-supporting horns extending from and integral with said walhand having shoulders a,pintlesupports integral with said wall and parallel with each other, arranged to bear upon or against the edges of said wall, and provided with'shoulders a which cooperate with the EDMOND B.

In presence of- JAMEs R. SUTLIFF, J. L. RUTHERFORD.
