SPECIFICATION forming part of Letters Patent 0. 695,368, dated March 11, 1902. Application-filed August 22, 1901. Serial No. 72,935. (No modeld To all whom it may concern.-
Be it known that we, RUSSEL BIGELOW and FRANK E. BIGELOW, citizens of the United States, residing at Vanwert, in the county of Vanwert and State of Ohio, have made certain new and useful Improvements in Chair- Trucks, of which the following is a specification.
Our invention is an improvement in roller attachments or wheel-supports for chairs, more especially rocking-chairs used by invalids.
The invention is a truck composed of two wheels and two axle-sections which are ad-' j ustable lengthwise upon each other and provided with bends or depressions adjacent to the wheels for receiving the chair-rockers or other base portion of chairs.
The details of construction, arrangement, and operation are as hereinafter described, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view illustrating the practical application and use of our invention. Fig. 2 is an enlarged perspective view of the truck. Fig. 3 is a vertical section on the line 3 3 of Fig. 2.
As shown in Fig. 2, the truck consists chiefly of two running or transporting wheels A and two axlesections B B. Thesaid axle-sections are lapped lengthwise one upon another and secured togetherwbyv means of clamps or clips 0, which are constructed of thin elastic metal having flanges through which screw-bolts c are inserted, as shown. It is apparent that by this construction the two axle-sections B B may be adjusted lengthwise one upon the other and may be secured in any adjustment by means of the clamps C. Adjacent to the wheel-journals the said axle-sections have downward bends or de- 'pressions B The said bends l3 are practically rectangular, and plates D are secured on the horizontal portions of the bends by means of rivets orbolts, as shown. These plates are are shape, being curved slightly,-
as shown in Fig. 3, to better adapt them to the rockers of a chair, as illustrated in Fig. 1.
In practical use the truck is employed as follows: The chair to which the truck is to be applied is tilted forward and the operator pushes the truck forward with his foot beneath the rockers and then allows the chair to fallbackward, when it will rest upon and be supported by the plates D, as shown in the'construction shown the truck may be adjusted for chairs having rockers arranged at any distance apart. While the truck is particularly adapted for use with rocking-chairs, it is apparent that it may be applied or used with other chairs having bot-tom side rounds which are near the floor. The wheels A are preferably constructed similarly to those of the safety-bicycle, being provided with a rubber tread and a skeleton frame.
It will be noted that the axis of the axle journals 1) is in a line slightly above the body of the axle-sections, whereby the bends B willalways tend to hang vertically and to maintain their position better than if the journals were'in line with the body of the axlesections.
What we claim is- 1. A chair-truck having an axle formed of two parts adapted to slide lengthwise upon each other, means for securing the parts of the axle together, the axle being depressed and thereby adapted for engagement with the baseof a chair for supporting it in the manner described.
2. The improved truck comprising two wheels, two axle-sections which are adjustable lengthwise upon each other, means for securing the axle-sections in any adjustment,
and the said sections having each a downward bend or depression adapted to receive the rockers or other base portion of a chair, substantially as shown and described.
3. The improved chair-truck comprising two wheels, two axle-sections which are adjustable lengthwise upon each other, clips applied to the lapped portions of the axle-sections, means for clamping the said clips upon bends provided with plates adapted to serve as rests or supports for chair-rockers, and the journals of the said sections being in line with each other above the central lapped porr 5 tions, substantially as shown and described.
