My present invention is concerned with exercising machines and has among its objects to provide a simple and rugged apparatus, which serves effectively to exercise those muscles commonly used in bicycle riding, and in horseback riding, as well as those used in operating a rowing machine.

An object of the invention is to provide a machine of the above type, in which the user does not exert affirmative effort, butl on the contrary, muscular movement is mechanically imposed upon him regardless of whether he tries to relax or to resist such movement.

Another object is to provide a machine of the above type, capable of being operated from a fractional horsepower motor, which will yet afford exercise adequate for even powerful individuals.

Another object is to provide a device of the above type, by which the complex rhythmic relal' tive movements of the legs, arms and body of the user are effected, with the use of conventional transmission gearing and linkage not subject to jamming or noisy operation.

Another object is to provide a machine of the above type which admits of ready adjustment with respect to the height, weight and age of the user.

Another object is to provide a machine of the above type, which in operation will not cause any injury to the floor, rug or other support on which it may stand when used in any ordinary room of a dwelling.

The invention involves a support frame or chassis carrying a pedal crank member, a seat and a handle bar, and an electric motor operating the pedal through a gear reduction, and preferably also connected by linkage to said seat and handle member for moving the same in a cycle by which is brought about the desired co ordinated exercising movement of the user.

In a preferred embodiment the chassis carries a transmission box driven from thermotor and driving the pedal crank shaft, preferably through a worm drive, and also driving the seat and handle supportsE preferably by means of a connecting rod, protruding from the transmission box and operated from a crank or other eccentric member therein which is driven from the pedal crank shaft. Y

Preferably a generally horizontal control bar pvoted to the frame is operated from the connecting rod, the movement of said control bar being resisted by a coil spring connecting the free end of said bar to the frame and the tension York, N.

(Cl. 12S-33) Cil of which is controlled by adjustably positioning the upper spring carriage thereof along said control bar. The seat and handle bar are mounted on corresponding support bars, one of which, preferably the seat carrying bar, is pvoted to the frame, the other, preferably the handle bar, pivoted at one end thereof, to the f1rst of said bars, and between its ends to said control bar.

Referring now to the drawings, the device comprises a chassis or framel preferably made of metal tube stock, which may include a pair of transverse and inwardly inclined U-shaped foot members Il the legs of each of which are connected at their ends by a transverse brace I2. The foot members are connected by a pair of longitudinal rods I3 forming the chassis. Each of rods I3 is reversely bent at its forward end to form a trapezoidal side frame I5 with a horizontal upper base IB the downturned extremity of each rod being Welded at I1 to the longitudinal portion I3 thereof. Longitudinal brace rods I3 are connected at their ends to the respective cross braces I2 and their intermediate portion extends horizontally at I9 under, along and in contact with the chassis rods I3 to which they may also be welded.

Upon the chassis and between the side frame pieces I5 is mounted the transmission box B, hereinafter to be described. It may be attached by screw |02 threaded into boss |03 and exerting pressure through clamp plate IM against brace taken on line 1-1 of on line on line rods I9. Through the lateral walls of box B protrudes the pedal crank shaft 20 mounting the conventional bicycle pedal cranks 2| and pedals 22. Through the upper part of the transmission box protrudes a connecting rod 23 pivoted at its upper end 24 to an intermediate portion of the control bar 25 which in turn is pivotally mounted at 26 between the horizontal parts I6 of the side frame, and effects the relative movement of the seat and handle now to be described. To this end the seat and handle members are preferably mounted upon corresponding bars pivotally interconnected, the assemblage thereof being pivotally mounted upon the support frame. In the specific embodiment shown the seat 21 which may be a more or less conventional motorcycle seat, and is preferably of metal, is mounted by its central rin 28 to the upper end of a bar 29, the lower' end of which is pivoted at 30 preferably to a n 3| cast on the transmission box B.

The handle bar 32, which may be similar to that of a motorcycle, is centrally clamped in a corresponding collar 33 at the upper end of a supporting bar 34 therefor, the lower end of which bar is pivoted at 35 to the seat supporting bar 29 and which is pivoted between its ends as at 36 to the extremity of the control bar 25. Preferably, the collar 33 has the usual clamping screw 31 thereon for adjustably positioning the handle grips 32' in accordance with the arm length of the user.

If the seat 21 were rigidly mounted upon its support bar 29 it would tilt with the movement of said bar in pivoting about pin 30. Means is therefore provided to maintain the seat at a comfortable and safe angle throughout the motion thereof from between its extreme forward and its extreme rearward position. A parallel motion linkage is, therefore, provided to assure substantially a translational movement of said seat parallel to itself. For this purpose, the mount of the seat 21 on the bar 29 is by means of a pivot screw 38 and a parallel motion link 39 is pivoted at its upper end to the front of the seat at 45, and its opposite end, (formed as a clevis 4| straddling the bar 34) is preferably pivotally mounted on pins 42 at corresponding ears 43 welded to the side frame |5. In the embodiment shown in Fig. 2 of the drawings, the lower ends of the bar 29 and link 39 are pvoted at fixed bearings 3U and 42 respectively, the line connecting which is at a considerable angle to that connecting the upper and movable ends of said bar and link shown respectively at 38 and 4|). For true parallel motion said lines would have to be parallel. The seat in the embodiment shown does not move strictly parallel to itself, but in the rearmost position, it tilts downward slightly with respect to the position assumed at the forward part of its movement. The term parallel motion linkage as used in the claims, is intended to embrace within its scope the showing in the drawings in which the seat is controlled by link 39 to pivot about its pivotal mount 38 to be maintained in substantially but not necessarily in strictly parallel relation.

To resist the pivotal motion imparted by the connecting rod 23 to the control bar 25 a heavy coil spring 44 is provided, pivotally anchored to the frame at one end and to the control b-ar at the other. The frame mount may comprise a screw 41 with a spherical head 46 housed in a corresponding socket 48 in a foot 45 cast with the box B. The shank of screw 41 is screwed through the button 49 which is gripped by the lower turns of the spring 44. The upper end of the spring has a corresponding button 50 pivoted at 5I to a carriage 52 formed as a. sleeve which encircles the control bar 25. A screw 53 threaded through said carriage 52 is rotatably mounted at its ends in corresponding ears 54 on the control bar. By means of a handle 55 at the forward end, the screw 53 is turned and the carriage 52 thereby caused to be moved forward or backward to the desired position, for adjusting the tension of the spring 44. Preferably, as best shown in Fig. 9, a slotted scale plate 56 is attached at 58 upon corresponding studs 51 on top of the control bar 25. A corresponding pointer 58' affixed on a stud 59 on top of the carriage 52 travels in longitudinal slot 60 in the plate, to indicate the setting, preferably in terms of the weight of the user.

While, of course, it would be possible, to arrange the parts substantially as in my copending application, Serial No. 733,546 of July 3, 1934, issued February 8, 1938, as Patent No. 2,107,447, to operate the pedals by foot power, which in turn causes the movement of the seat and handle bars, it is preferred, according to the present invention, to operate the apparatus by a mechanical power drive. For this purpose, a fractional horse power electrical motor 6| is mounted, preferably at the rear end of the chassis and is connected by means of a drive shaft 62 to the transmission box.

While drive may be effected through any desired clutch, the drive shaft 62 is illustratively shown as a hollow shaft operating within a fixed tube 8|, and having a squared extremity 62 telescoped over the correspondingly flattened protruding extremity 63 of cross shaft 64 bearing in the front and back walls 65 and 66 of the transmission box B. A worm 61 upon said shaft 64 meshes with a worm wheel 68 keyed to the pedal crankshaft 20, which bears in the lateral walls 69 and 1U of the transmission box B.

The pedal crankshaft 20 also serves to deliver power to the connecting rod 23, by which the seat and handle mounting bars are operated. Desirably the cycle of movement of the handle bar or seat is at a frequency having a definite relation to the frequency, that is, the revolutions per minute of the pedal crank. To this end, power is transmitted from the worm wheel shaft to perform the complete cycle of pedal operation, at faster rate but at a definite ratio to the cycle of motion of the handle supporting bar, or of the seat supporting bar. In the specific embodiment shown, the pedal bars are mounted directly upon the worm wheel shaft, while a gear reduction is interposed between said worm wheel shaft and the drive for the seat or handle bar.

For this purpose a gear 1| keyed to shaft 2|) meshes with an idle gear 12 on stub shaft 13 in the transmission box, which, in turn, meshes with drive gear 14 on transmission crankshaft 15 near the upper part of the box. The crank 16 of shaft 15 affords the bearing for the lower end of the connecting rod 23. That rod preferably protrudes from the upper wall 11 of the box through a stuffing box 18 resiliently tightened by a coil spring 19 about the protruding end of the connecting rod 23 and reacting at its upper end, against flange 8U.

The use of the apparatus will be obvious from the above description. It may be briefly noted that after the user mounts the apparatus, as he would a motorcycle, and places his feet on the pedals, he sets the electric motor 6| into action by throwing the switch (not shown) which may be disposed at any convenient accessible place. The worm gear reduction 61-68 is such as to cause driving of the pedal crankshaft 29 at the rate of about 80 revolutions per minute. At the same time transmission crank 16 will move at desired speed, determined by the ratio of gears 1I and 14, preferably at approximately thirty revo-' lutions per minute. In this operation, the connecting rod 23, through the control bar 25 will exert alternate push and pull upon bar 34 at pivot 36. As the rear of control bar 25 moves downward about pivot 26, the forward end moves correspondingly upward and stresses the spring 44. In the downward pivoting of the rear of the control bar, the handle support bar 34 is lowered therewith, said bar 34 correspondingly depressing the seat support bar 29 about its pivot 39, by virtue of the thrust delivered through pivot 35. The portion of the control bar 25 between the pivots 26 and 36, forms with the portion of the handle support bar 34 between the pivots 35 and 36 a toggle, so that said pivots 35 and 36 moving through distinct paths cause said bar 34 to tilt forward about pivot 35 and about the control bar pivot 36. Of course what is designated as the toggle, does not become completely set, for, even in the extreme position, the link 25 and the lower part of bar 34 form a large obtuse angle relative to each other, but never reach straight angle or toggle locking position. The extreme position of the downward and rearward movement of seat 21 and the concurrent downward and forward movement of handle bar 32 (shown in Fig. 2 in dotted lines) is reached when the transmission crank 16 has reached lower dead center. As the crank 16 passes dead center position, the stressed spring 44 aids the motor in the return movement, in which the seat 21 and the handle bar 32 perform the reverse of the motion previously set forth, and reach their position of closest approach when crank 16 reaches upper dead center.

Thus in operation, the user, without exerting any affirmative eort, is constrained to perform repeated cycles of vigorous muscular movements. His legs are caused to perform a pedaling motion. At the same time his trunk and arms are caused alternately to be bent over and stretched by the rearward movement of the seat and the concurrent forward movement of the handle bars and then to be straightened and relaxed by the return movement of the seat and handle bar.

As appears from the drawings, the simultaneous backward movement of the seat and forward movement of the handle bar with respect to the fixed position of the pedal crank shaft 26 helps to maintain the body of the user in balanced position.

In the pivoting movement of seat mounting bar 29. the seat 21 moves through a substantially1 translational path, at no time tilting excessively from horizontal, since the parallel motion link 39 compensates for the excessive tilting otherwise incurred, as above set forth.

The aliernative embodiment of Figs. 6 to 8 is generally similar to that described, except that it includes selective gear reduction for greater flexibility of operation. in accordance with the physical condition of the user. Corresponding parts bear the same reference numerals, primed. In general, the transmission box B resembles that of the other embodiments, but it differs in that the worm 61' is on a couniershaft 90 parallel to the motor driven shaft 64 and propelled at either of two alternative power speed reductions depending on the setting of a gear shift. For this purpose, a pair of alternative driving gears 9| and 92 are keyed on shaft 64 and a pair of alternative driven gears 93 and 94 are loosely mounted on countershaft 90. The gear transmission 92, 94, affords a greater reduction than the gear transmission 9|. 93, because the drive gear 92 of the former is smaller and the driven gear 94 is larger than the corresponding elements of the alternative drive. Driven gears 93 and 94 have clutch teeth 95, alternatively engaged by corespondingly conformed teeth on clutch sleeve 96 keyed to countershaft 90 between gears 93 and 94, and positioned by means of a yoke 91 straddling the same, the shank 98 of which yoke is mounted on the end of an arm 99 which may be turned by means of an exposed handle |00. A coil spring |61 resiliently retains the clutch SE in one of the other of the two positions as desired. The transmission box of Figs. 6 to 8 is interchangeable with that of Figs. 3 and 4, and admits of either a fast operation of the pedal say at R. P. M. cr a lower operation say at 40 R. P, M., in each of which the motor 6I operates on full voltage.

It will thus be seen that there is herein described apparatus in which the several features of this invention are embodied, and which apparatus in its action attains the various objects of the invention and is well suited to meet the requirements of practical use.
