TRUCK FoR ROLLER-SKATES.
SPECIFICATION forming part of Letters Patent No. 508 ,617, dated November 14, 1893. Application filed February 3, 1893. Serial hie- 460.333. (No model.)
To all whom it may concern.-
Be it known that I, CHRISTIAN G. HoERLE,
a citizen of the United States, residing at Torrington, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Trucks for Roller- Skates; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which'it appertains to make and proper shape to support the axle and to pro vide suitable means for attaching it to the platform or sole plate of the skate, which improvement will be more fully set forth and described in the following specification and such features as I believe to be new and novel particularly pointed out in the claims to follow.
To enable others skilled in the art to make and use my invention reference is bad to the following drawings and to the figures and letters of. reference marked thereon which together with the specification explain the device.
Figure 1, represents a side elevation of a roller skate embodying my improved truck,
3 5 one of the rollers in the foreground being removed to give a' better view of the improved truck frame. Fig. 2, is a rear elevation of the hind truck with the wheels removed, looking in the direction of the arrow shown in being a central section of the frame through 'it is called upon to bear.
line y of Fig. 3 and a central sectional view. of the bushing therein.
Thefirst operation in the construction of my improved truck, (see Fig. 4) is to blank out the frame from sheet metal of the required thickness-which for this purpose is comparatively thinand to form such blank in any shape best calculated to distribute the stock with proper regard to the strain which The central portion 1 will form a support for the axle presently to be described. The arms a. b terminate into the enlarged plates 0. d, at each extremity thereof, in each of which are formed the holes e by which the frame is attached to the underside of the foot plate 2 shown in Fig. 1. To strengthen the frame the depressions or indentationsflfare made in the surface of each of the arms a. b,-as shown at Fig. 5.
After the blanking process above described, the blank is bent by means of the proper tools into the completed form shown in Figs. 1, 2 and 3 and attached to the foot plate 2 by means of the screws 3. The central portion 1 of the truck frame is bent around the supporting eye 4Fig. 6for supporting the axle 5 shown mounted therein atFig. 2. This axle is driven into the eyeof the said truck frame and has mounted on each projecting end the two Washers or collars 6, Which collars are placed. between the ends g of the central portion 1 of the truck frame and the spring linch pins 11 which are inserted in holes arranged transversely through said axle and near the ends thereof. 7 In the construction shown in Fig. 6, I may find it advisable in some, or in all cases, to further strengthen and reinforce the axle supporting part 1 of the truck frame, by plac- 9c ingin the eye 4 thereof the bushing or eyelet 8 and flare or upset the projecting ends it against the projecting ends 9 of the central portion 1 of said truck frame.
In the construction above described I produce a frame much lighter, cheaper and stronger than the ordinary cast metal truck frame now employed. Besides, such a construction is equally well adapted in use to be applied in the construction of casters for 100 beds, tables, chairs and other like articles. Therefore I do not wish to be strictly confined in its use to roller skates,bnt to employ it in other lines as Well.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a roller skate or other device of like character, an improved article of manufacture consisting of a roller-truck frame made from a single metal blank formed into the proper shape to be attached to the foot-plate of the skate and means substantially as shown for attaching it thereto, a bend or eye formed at or near the lower depending end of such frame for supporting the axle for the rollers; substantially as set forth.
2. A roller-truck frame madefroma single piece of sheet metal and bent around as shown to form an eye at its lower depending end,
' combined witha bushing or eyelet inserted the purpose described.
In testimony whereof I affix my signature in presence of two witnesses.
