for an indefinite period without maintenance service, such as lubrication, repairs, or replacement of parts.

A further object of this invention is to provide an exercising device of the character described which includes an operating handle and means for providing resistance to movement of the operating handle in either direction from its neutral or median position.

A still further object of this invention isto provide a device of the character described including means for adjusting the initial or neutral angle of the operating handle, whereby the arc of movement may be adjustably determined to suit the operator.

Another object of this invention is to provide, in a device of the character described, a handle bar and means for adjustably positioning the handle bar to vary the length of the stroke, and to adapt the device to the length of the arms of the operator.

Again, an object of this invention is to provide a simple, light weight structure of the character described which may be folded or collapsed into a compact, flat package for transportation, packing, or storage.

These, and other objects and advantages of this invention will be completely and concisely disclosed and described in the following specification, the accompanying drawings, and the appended claims.

Broadly, this invention comprises a frame, a seat secured on one end of the frame, a handle pivotally secured adjacent the opposite end of the frame, a cylinder pivotally supported on the frame near the seat end, a piston slidably supported in the cylinder, compression springs in the cylinder engaging both sides of the piston, a connecting rod secured to the piston and pivotally connected to the handle, means for adjustably positioning the pivotal connection of the connecting rod and handle, a handle bar, and means for adjustably positioning the handle bar in the handle relative to the pivotal connection of the handle on the frame.

A preferred embodiment of this invention is illustrated in the accompanying drawings, in which- Fig. 1 is a perspective view of the exercising device,

Fig. 2 is a cross section through the handle,

Fig, 3 is an underside plan view of one of the end or cross bars,

Fig, 4 is a perspective View of the front cross bar or foot brace,

Fig. 5 is a cross section illustrating the removable pivot pin and piston connecting rod, taken on the line 5-5 of Fig. 6,

Fig. 6 is a longitudinal sectional view of the exercising device,

Fig. 7 is a cross section taken on the line 1--1 of Fig. 6, and

Fig. 8 is a cross section of the cylinder, taken on the line 88 of Fig. 6

Referring now to the drawings in detail, in which like numerals refer to like parts throughout,

A pair of frame members I are bolted or otherwise secured at front and rear ends to cross bars 2 and 3, respectively, in parallel, spaced relation, as best indicated in Figs. 1 and '7. Foot pads 4, of rubber or other suitable resilient material, are secured on the under side of the cross bars 3 and 4 in angular or toenailed relation, thereby providing resistance against both longitudinal and transverse movement of the device when it is placed on a floor or other supporting surface. The front cross bar 2 is chamfered on either side of the frame members I, as indicated at 5, to provide angular surfaces against which the feet of an operator of the device may be braced. A seat 6 is secured on the upper surfaces of the frame members I, over the rear cross bar 3.

A handle 8 is pivotally secured between the frame members I, adjacent their front ends, by means of a pivot pin 9. A handle bar In is slidably and removably supported in one of a plurality or holes I l formed in the upper portion of the handle 8, The diameter of the grip portions l 2 of the handle bar In is small enough to permit withdrawal of the handle bar In from the holes H, as best indicated in Fig. 2.

A cylinder I3 is pivotally supported between and near the rear ends of the frame members I by means of a pivot pin or stud M. A piston I5, provided with a connecting rod [6, is normally positioned midway in the cylinder l3, as indicated in Fig. 6, and compression springs I1 and I8 are supported in the cylinder l3-on either side of the piston IS. The spring l1 bears against the stud l4 and the piston 15, and the spring 18.

bears against the opposite face of the piston l5 and a screw cap l9 removably secured over the front end of the cylinder l3. The springs I! and I8 are enclosed in sleeves of resilient, absorbent material such as cloth fabric, or the like, which may be soaked in a lubricant, either liquid or semi-solid, as oil or grease. The front end of the connecting rod I6 is provided with a head 2| which extends into a slot 22 formed in the handle 8, and is pivotally connected to the handle 8 by means of a pivot pin 23 engaged in one of a series of spaced holes 24 formed in the handle 8.

The device may be operated by a person seated on the seat 8 and grasping, with the hands, the handle bar ID. As the handle 8 is pulled toward the body, resistance is offered by the spring 11, and this resistance increases with the distance through which the handle is moved from its neutral position. When the handle 8 is pushed away from the body, resistance is offered by the spring I8, which acts in the same manner as the spring H, but in reverse direction. Thus, effort is required to move the handle in either direction from its neutral position. No effort is required in returning the handle to neutral position, as the reaction of the springs l1 and I8 control these movements.

Adjustment of the length of swing of the handle 8 is controlled by adjustably locating the handle bar l0, and the neutral angle, or starting position, of the handle 8 is controlled by adjustably positioning of the pivot pin 23 in the holes 24.

With the pivot pin 23 and handle bar In removed from the handle 8, the cylinder [3 and its connecting rod I6, and the handle 8 may be lowered to rest between the frame members I, as indicated by dash lines in Fig. 6, thereby providing a fiat, compact package for storage, packing, and transportation.

If desired, a cap 25 may be secured on'the lower end of the cylinder I3, and the cylinder packed with grease or other suitable lubricant.

Preferably, the members I, 2, 3, 6, 8, and ID are made of wood, or of a material having an equal or less specific gravity with wood, thereby providing an extremely lightweight apparatus which may be easily lifted or carried. Such a construction also results in economies in transportation and distribution.
