Description
Oct. 5 1926. R. w. DAVIS HAND AND FOOT POWER DEVICE Filed A ri'i 18, 1922 g Y I/INVENTOR R am; 7 Day/s Patented Get. 5, 1926 ROBERT W. Davis, on ozone reannnw YORK.
nannann'roo'r' Application filed April is;
This invention relates to power devices and particularly to the type wherein'the' use of the hands will aid in doingthe work as well as the feet.
Another object is to provide a device which will have few parts, be capable of manufac-- ture at low cost and will make use of all of the operators energy.
While I am aware that various devices fthis' kind have been producedin'the past, I believe that the same have lacked a feature, that is highlyimportant. So the success of such devices that is the combined use of the arms and legs for operation in such a manner as to obtain the maximum amount of power.
Another equally important bject is the provision of a specially shaped operating shaft through which the combined power" produced by the operators legs and arms will be delivered.
Other objects and advantages in'the structure will be brought out in the following specification and drawingin the latter of which:
Fig. 1 is a front elevation of device showing the relation of the operating elementsr Fig. 2 .is a side elevation of my device.
Fig. 3 is an enlarged section taken on line 3-3 of Fig. 1.
Referring to the drawings in detail designates in its entirety a power device comprising a center bar or frame 11 made of wood or any suitable metal. For the pur pose of illustrating my invention I am showing it as a polished wooden bar, the upper portion of which may be square as at 12, to accommodate the guide plate 13 attached thereto, the purpose of which will be hereinafter explained.
The lower end of the bar 11, has attached thereto a bearing 14, in which the journal portion 15 of the crank shaft 16 revolves. This bearing 14:. in the event that a metallic bar 11 be used, may comprise a bearing memher having; a threaded bore, into which the lower end of the bar may be screwed. It is to be understood that bar member 11 may be made of aluminum tubing or any light metallic construction, in which case the bearing e1 iber 1% would bemade integral therewith or could be soldered thereon.
For the purposeof illustration the side having the breast straps shown in Fig. 2 at tached thereto, will be called the back of the device.
PO'W'ER DEVICE.
an; Saar 1th; same? The bearing 14* forms the upper terminus;
of a lightly constructed bracket 17 which is" inte ral therewith; Spaced guide collars 18 are -I-ormeo-on said bracket and support the? power shaft 19, to thelow'ereiid" ofwhich' is suitably secured a gear or pulley through" whichth'e power be traiisrnitted to as useful work.
To the upper endof shaft" and resting on top of the upper guide collar'l s' is suitably secured a bevel pinion 21 whichis'op erat'edthrough the; medium of a bevel gear 22 pinned to the journal portion 15 of the crank shaft- 1-6 and adapted to -"revolve there 7 with. It can thus" bes'eeii uponin'spection of Figs; 1 and 2thatthe bevel pinion12 1and gear 22 are held infixed spalCedrelzttidn; V The crank shaft 16 isbentto aparticular cornigura-tioii that is a'll thepoints' on said crank shaft to which force is applied by" either arms or" legs, are" the same distance-" from the turning point and therefore 'trav'el in the'same diameter, of circle. These posi tions are ran-mar by bending the (resa e so shaft 16 on the left'* side of the" device (as indicated by the 'L in- Figs- 1 and 2 up? wardly'andrearwardly'as a-t23 arid-to form a journal'2et which is engaged by the left arm-operated member 25. The crank shaft is then bent downwardly and forwardly as at 26 and to form a pedal supporting portion 27. The crank-shaft on the right side (as indicated by R in Figs. 1 and 2) is bent in the opposite directions, that is, it ex- 9 tends down and forward to form the journal 28 for the right arm-operated member 29, .and up and to the rear to form a pedal supporting portion 30. Suitable straps 31 may be used to keep th operators feet uponthe pedals.
Suitably attached to the upper ends of the arm operated members 25 and 29 are hand grips 32, which are held adjacent to the guide plates 13 on the frame 11. The
guide plates (Fig, 3) are attached as by screws, to the upper portion of the frame 11 so as to form slots 33 therebetween for the reception of pins 34 having enlarged portions 35 formed thereon. tions 35 lie between the guide plates and the frame and are adapted to partake of the reciprocations of the handles 32.
To the upper end of the frame may be attached a leather, canvas or rubber adjustable body encompassing member 36.
A seat 40 may be provided which is se- These por- 0 cur-ed to and has suitable adjustable relation with the frame 11. The arm operated members 25 and 29 may also beprovided with suit-able adjusting means whereby their length may be decreased or increased as necessary.
In operation the device may be fastened to the body of the wearer, and through the medium of adjustment of seat and arm operated member can be made to fit any person.
The right arm-operating member 29 will be at its lowermost position when the left pedal has passed the vertical center line of the device, and until this time, it can be seen upon inspection of Fig. 2, the left armoperating member 25 will assist the horizontal 0r crosswise movement of the right pedal. With this arrangement there is imparted to the shaft 19 a continuous rotary movement which will be nearly equal at all times. In the present devices when the feet are up and down respectively, there is a slowing up of the power shaft 19 due to passing the dead center or the point at which the feet of the operator act in a downward direction.
When the right hand crank 28 goes through the lower quadrant as at A, the left pedal 27 passes through the front quadrant as at B. This allows of the right arm be ing straight when the left foot goes down, the reason for this condition being that the greatest pull can be made with the arm straight. A much weaker pull is made with a bent arm. The same condition is true regarding the left arm and right foot operating members.
Having described my invention, what I claim is:
1. In a combined hand and foot power device, a frame, hand gripping elements slidable on and parallel to said frame, a crank shaft, foot-pedals thereon, said hand elements being connected to said shaft, and said shaft being so shaped that one arm of the operator is extended parallel with the frame of the device when one foot is forcing a pedal down.
2. A hand and foot power device comprising a crank shaft, a frame, hand operated elements attached to and slidable on said frame and attached to said crank shaft, foot pedals on the outer ends of said shaft, and said shaft, pedals and hand operated elements being so arranged that a force greater than the weight of the operators body may be applied to said pedals.
3. A hand and foot power device comprising a frame, guide members disposed on one end of said frame, hand operated members slidably held in said guides, a crank journaled in the lower end of said frame, foot pedals on the outer ends of said crank, said hand operated members being connected to the crank intermediate said foot pedals, and the foot pedals and hand operated members being spaced ninety degrees apart at their point of connection with said crank.
