NICHGLAS M'. OEHLBERG, OF CHICAGO, ILLINOIS ORTHOPEDIC DEVICE i Application led December'Sl, 1930. Serial N0. 505,755. l
My present invention relates to the provision of improvements in lorthopedic devices,and an object of` my invention is to.
provide a device for the correction of various inequalities and weaknesses of the humanr to provide a device j body, and particularl which may be used or balancing the two sides of the body, namely, the right and left sides. It is well known that many children ,lo are weak in some manner and strong in others, and my present invention may be used under proper instructions and `Care to correct such conditions. Another object of the invention is to provide a simple device of the character described, in that it is easy to manufacture and easy to maintain.
A further object is the provision of a device of the character described vwhich may be used to correct an abnormality of the legs o or arms, the right leg and right'arm when the left side is normal, the right leg and left arm when the remaining members arenarmal, and various other combinations of weaknesses.
Other objects will appear hereinafter.
In the drawings,-
Fig. 1 is a perspective view of one form of my device;
Fig. 2 is a section view, taken substantiallyy V on the line 2 2 of Fig. 1;
Fig. 3 is a view partially in section and partially in elevation, the sectional portion being taken `substantially on the line 3 3 of Fig. 2;

Fig. 5 is a detail View, partly in sectiony land kpartly in elevation, and taken substantially on the line 5 5 of Fig. 1;
Fig. 6 is a detail view of the seat or saddle wheel, and the parts in section show there-H cesses of the shaft which are adapted to re- 50. Ceive a bolt from the crank arm in order to Each shaft is provided with recesses 21 for Fig. 4 is a detail view of the sprocket wheel, sliaft and other parts, and the portions in' .which are widened and gradually converge to y Washer or indicator in the same relative posi- -hold the crank arm on the shaft in a rigid manner; y y
Fig. 8 is a detailview of the shaft and manner of attaching a cranky arm so that the shaft and crank arm will turn as one unit;
Fig. 9 is a view partly in section and partly in elevation, taken ysubstantially on the line 9 9 of Fig. 8.
Referring more particularlyto the drawings, this form of my invention is provided with a frame or supporting member 10, seat or saddle 11, saddle post 12, crank arms 13 for use by the hands, and crank or pedal arms 14y for use by the feet. A housing 15 is pro- 65 vided for the covering kof thesprocket wheel, chain and other portions of the present form of my device. Suitable handles 16 and suitable pedals 17 rare provided for the use by the person employing the device.4 It can be seen that the presentrform of my device is provided with two saddles and may be used by two persons jointly, that is, onefperson employing a handle and pedal, or another combinatlon of these.
In Figs. 2, 3, 4, 7, 8, and 9 the internal working parts of the device are shown clearly and the Vdevice is provided with a suitable sprocket .wheely 18, shaft 19, and chain 20.
the reception of bolts 22 which extend `through crank arms 13 and 14and maintain vthe crank arms yin such a manner that `they Will turnwith the shaft, or upon the disengagement of bolts 22 the shaft may turn independently of the crank arms. As rshown more clearly in Figs.`8 and 9, recesses 21 are rendered' more accessible and more easily found bythe provision of inclined surfaces 23 the size of recesses 21 these inclined surfaces 23are desirable for the purpose of effecting a more ready engagement of the bolts by the recesses 21. In order to facilitate the vlast mentioned operation, that is, in engaging the shaft by bolts 22, lan indicator'or washer 24 provided with a lug 25 vfor designating the position'at whichl the shaft is'located at anyl particularA timeand rin order to maintain this tion appropriate lug portion 26 on the was er is engaged by a recessed slot 27 of shaft 19; that is, the indicator is maintained at all times in the same position on the shaft. Suitable anti-friction ball races 28 may be provided for the reduction of friction in the turning of the shaft. Y
The crank arms are maintained on the shaft by means of bolts 29 which are provided with enlarged heads which may be used for the purpose of holding the shaft in a particular location while bolts 22 are turned into recesses 21. It can be seen that there are two recesses in each shaft, and they are vlocated approximately 180 degrees from each other so that they are on opposite sides of the shafts.
For the provision of a device which may be used by different sized individuals, saddle vided for sustaining the. weight of the shaft for the upper crank arms, as distinguished from the pedal arms. As can be seen in Fig. 1, housing 15 is also provided with lugs or ears 35 which are suitably slotted, and plates 34 are tapped to receive a bolt through ears 35 for the purpose of holding the shaft from upward movement.` Plate 34, as viewed from the right of Fig. 1, is removable and may be removed by disengagin g bolts 36' from appropriately tapped portions of vthe top bar or frame 10. Housing 15 is also provided with L-shaped lugs 37 which are adapted also to hold housing 15 and parts within it from vertical movement. The lower cup-like portions of housing l5 are also provided with ears or lugs 38 which are provided with appropriate slots through which are adapted to .bereceived bolts for engagement by appropriately tapped recesses in the lower bar members of frame 10.
As can be seen from the foregoing description, my device may be used for giving eXerf cise to the arms and legs, and because of the provision of oppositely positioned recesses in thAe shafts, the device may be adjusted to respond to what might be termed reciprocatory motion, that is, with one hand and one foot up and one hand and one foot down, or by proper adjustment these movements may be changed to what may be termed unisonous movement, that is, movement by having both hands in the same vertical position and the feet likewise in the same vertical position. In order to effect the last mentioned adjustment, it is necessaryonly to loosen bolts 22, turn crank arms'l and pedal arms 14` into similar positions. If the particular individual is weak on the left side and normal on the right side, the crank arms and ped-al arms of the right side may be disengaged by disengaging bolts 22 on the right side, and thus leaving them free. It can be seen that the left side only would then be turned with shaft 33.
For the correction of certain deficiencies of the body it is desirable to reverse the movements of exercises, making the movements what might be termed reciprocatory, and also to make them whatmight be termed unisonous, as above described. My device may be used for all these movements for shafts 19, and sprockets 18 may be turned in either direction.V and the reciprocatory and unisonous movement may be provided for as before described.
Two individuals mayuse the device at the same time for the exercising of their respective right members and their left members,
vand thus for children an element of amusement or sport may be found in using the device.
While Ihave described and illustrated one form of construction for carrying my invention into effect, it is capable of variation and modification without departing from the spirit of the invention, and I therefore do not wish to be limited to the precise details of construction as set forth, but desire to avail: myself of such variations and modifications as come within the spirit of the invention.
I What I claim as new and desire to secure by Letters Patent is:
A device of the character described comprising a frame, a seat mounted on said frame, means on said frame for supporting ashaft, a shaft supported by said means, a sprocket wheel affixed to said shaft, two
sockets in and adjacent each end of said shaft into either of said oppositely placed sockets. L
In testimony whereof I have signed my name to this specification.
