CUSHION-FRAME FOR BICYCLES 0R LIKE VEHICLES.

4 SPECIFICATION forming part of Letters .Patent No. 707,262, dated August 19, 1902.

Application filed January 18. 1902. Serial No. 90,286. (No model.) l

To @ZZ whom it may concern:

Beit known that we, JAMES H. SAGER and GEORGE D. GREEN, citizens of the United States, and residents of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Cushion-Frames for Bicycles or Like Vehicles, of which the following is a specification.

This invention relates to cushion-frames for bicycles and like vehicles, and has for its object to relieve riders of such vehicles from the jarring and shaking ordinarily occasioned by rough roads and obstructions encountered i the road.

The peculiar features of the invention are disclosed in the drawings and are particularly pointed out in the following-specification.

Figure 1 of the drawings shows in side elevation a part of the fra-me of a bicycle, the position of the rear wheel and the location of certain parts being indicated by dotted lines; and Fig. 2 is partly a section on the line 2 2 of Fig. l and partly a rear View of a portion of the frame broken away, so as to show the construction.

A represents the front section of the frame, with the exception of the head, which is not shown.

B is the horizontal barrel, `which is the crank-hanger; C, the rear-wheel fork, which D the rear braces, which are each iiexibly connected with a member of the fork C,as by the bolt d.

D' is a brace for the rear braces D. The hanger B, the fork C, and the braces D constitute what will hereinafter be referred to as the rear section of the frame. The front and rear sections of the frame are iiexiblyy connected at the hanger B, as by ears b and the bolt b. The sections of the frame are also flexibly connected at the upper ends of the braces. A clip or bracket E, rigidly' secured to the front section, supports a crossbar whose ends rest upon springs within the braces D D. This cross-bar is in the construction shown composed of the blocks F F, which are supported by means of arms G G, respectively, which in turn lie within the socket e in the clip E and which are adjustably fastened together, as by the screw g. The blocks F F are adapted to lit within the tubular braces D, respectively, so as to slide freely within them, and are enabled to slide within said braces by the longitudinal slots d d', which receive and permit the passage of the arms G G, respectively. At the point where thearms G G join the rods F they are cut down, as shown in Fig. 2, so that the slots d CZ may be narrower lthan they otherwise would be.

The adjustable connection of the. blocks F F, as by means of the lscrew g, obviates the necessity of accuracy in the construction of the arms withY reference to the distance between the braces D D which otherwise would 'be necessary in order to secure the eifective operation of said `blocks within said braces. The separableconnection within the arms G G afforded by thescrew g also enables the parts to be readily assembled and taken apart.

Within the tubular braces D D are respectively two coiled-springs H H, which may be seated at the lower ends of said braces, respectively, or in any suitable manner, as on a pin d3. (See Fig. l.) The tubular braces D D are represented as straight and parallel for their full length in order that springs of maximumilength maybe employed. The upper ends of these springs lie, respectively,

against the blocks F F and are preferably under slight tension when in their normal position, (shown in Fig. 2,) so that the parts will not rattle. Stops of suitable form, such .as caps D2 D2, are screwed into the tops of the tubes D D, respectively, and a packing cl2 d2, of rubberor other suitable material, is placed within said tubes D D, respectively, beneath the caps D2 D2 to receive the rebound oft-the blocks E E when the springs H H are relaxed. y

The operation 4of the device is as follows:

When by reason of the roughness of the roadV or of an obstruction encountered by the wheels the weight of the rider is brought suddenly upon the frame, the front section will turn upon its lower pivotal connection with the rear section at the hanger and the blocks F F will sink down into the tubular braces D D against the yielding resistance of the springs H H, said tubular braces and blocks F F at the same time alining themselves to IOO each other by turning at the point Where they are respectively connected iiexibly with the fork C and the bracket E. By this construction very long coiled springs maybe employed which will give great elasticity to the frame, for the springs may, if desired, be extended down into said braces for practically their whole length, and at the same time a construction is had in which the seat-post and saddle can be placed Well down upon the frame.

What we claim is- 1. The combination of a rigid front section; a rear-Wheel fork flexibly connected therewith at the cran k-hanger; tubular rear braces flexibly connected with said fork; a slot in each of said braces at its upper end; a spring Within each of said braces; a seat for the bottom of each of said springs; a cross-bar flexibly connected With the front frame and passing through said slots; a block Within each of said braces resting on the spring in the brace and secured to said bar and free to slide Within said brace; and a stop in each brace above the block.

2. The combination of a rigid front section; a rear-Wheel fork fiexibly connected therewith at the crank-hanger; parallel tubular braces flexibly connected with said fork; a slot in each of said braces at its upper end; a spring Within each of' said braces; a seat for the bottom of each of said springs; a crossbar flexibly connected with the front frame and passing through said slots; a block within each of said braces resting on the spring in the brace and secured to said bar and free to slide within said brace; and a stop in each brace above the block.

3. The combination of a rigid front section; a rear-wheel fork iexibly connected therewith at the crank-hanger; tubular rear braces flexibly connected with said fork; a slot in each of said braces at its upper end; a spring within each of said braces; a seat for the bottom of each of said springs; an adjustable cross-bar flexibly connected With the front frame and passing through said slots; a block Within each of said braces resting on the spring in the brace and secured to said bar and free to slide Within said brace; and a stop in each brace above the block.

4;. The combination of a rigid front section; a rear-Wheel fork flexibly connected therewith at the crank-hanger; tubular rear braces flexibly connected With said fork; a slot in each of said braces at its upper end; a spring Within each of said braces; a seat for the bottom of' each of said springs; a separable crossbar fiexibly connected with the front frame and passing through said slots; a block within each of said braces resting on the spring in the brace and secured to said bar and free to slide within said brace; and a stop in each brace above the block.

5. The combination of a rigid front section; a rear-Wheel fork flexibly connected therewith at the crank-han ger; tubular rear braces flexibly connected with said fork; a slot in each of said braces at its upper end; aspring Within each of said braces; a seat for the bottom of each of said springs; abracket rigidly connected With the front frame; an adjustable crossbar revolubly supported Within said bracket and entering said slots; a block within each of said braces resting on the spring in the brace and secured to said bar and free to slide within said brace; and a-stop in each brace above the block.
