SPECIFICATION forming part of Letters Patent No. 248,121, dated October 11, 1881.
Application led March 2,1881. `(No model.)
4simple arrangement ofapparatn-s whereby a machine with only one pair of handles `or levers and a -platform arranged for the operator to raise himself by lifting upon said handles or levers may be readily converted into an arrangement for producing the same result by bearing downward on said handles or levers,
or one by which the said result may be effected by bearing down on one handle or lever by one hand and lifting on the other handle by the other hand; Ior both levers may be secured in a fixed position for use as lparallel bars.
rI'he essential feature of the invention 'con-i sists of a duplex pivotal connection of the working levers or handles and a detachable brace, together with an adjustable connection ofthe l rods with said levers, which couple them to'j the platform, whereby the fulcr-um is readily shifted from one side to the other of saidconi nection, as it is desired, -to raise the platform by lifting or pressing down; and there is a locking device in connection with the platform, connecting-rods, levers, and brace, by which said levers are secured in the position of par allel bars, all as hereinafter more vfully described, reference being had to the accompanying drawings, in which- Figure l is a side elevation, showing the adjustment for raising the platform by lifting, the parts being in the positions of the beginning. Fig. 2 is a similar view with the parts in the positions which they assume when the platform is raised. Fig. 3 is a side elevation, showing the adjustment for raising the platform by pressing down on the levers, with the positions as at the beginning of the operation. Fig. 4 is a similar view, showing the positions when the platform is raised. Fig. 5 is a side elevation, showing the levers locked in the parallel-bar arrangement. Fig. 6 is a front elevation. Figs. 7 and 8 are details ofthe detachable brace contrivance. and Fig. 9 is a detail in plan or top view.
A is the frame, to one end of which the platform B is pivoted by the parallel connecting bars 0, so fas to -be maintained in horizontal position while suspended by the single pair of connecting-rods l).
E represents the si'nlcrumstandards,rising upfrom 'the same end iof the bed-frame to which the platform is pivoted, for supporting the working-levers F; but said levers are pivoted at G to the links H instead ot' the standards, and theel-inks are pivoted to them at I, and midway between said pivots'G and I -saidlinks hav-ea brace, pi-voted to them, 'and said braces have la series of foot-rests, K, on the 4stan'dardsbelow pivots I, with which they are ldetachably-connected, both for shifting them up and down to vary lthe height of the levers tand Aalso 'for dispensing with the braces altogether when -tlhe platform is to be raised by lifting, their nsebeing only in the pressingldown and parallel-bar adjustments.
The rods D couple the leversand the .platform together. rI lhey are pivoted toth'elatter at M, so-as to vibratergswing thereon fromV one side to theother of the pivot N, by which brace -J and link H are connected, according as the opera/tor is to wor-k by lifting or press, ing down, and -to vary the leverage for varying Vthe ypower toY be exerted, also v'to suit the strength of different persons.l
The connection of the rods with the levers is made adjustable along them by means of the series of Astud-pins O, to which said rods, having suitable pin-holes, d, are to be connected detachably; and forregulating the rangeofthe movements of the platform the rods are provided with a range or series of these pin-holes d. Any other form ot' detachable connection, of course, may be used.
The locking device to secure the bars in the position represented in Fig.A 5 for parallel-bar exercise consists ot' the hooks R, attached to the bed-frame in suitable position for engaging the lugs S (see Figs. 5 and 6) when the platform is down and preventing it from rising.
It will readily be seen by the foregoingthat when the machine is to be used for lifting, as represented in Figs. 1 and 2, the brace J is detached from its foot-rest K, and the levers rest directly on the top of the standards E for their fulcrums, and the rods D are connected tothe levers anywhere along the series of holes O, according to the leverage required, the lift being heavier the more the rods are shifted toward IOO the hands; but when the pressing-down operation is to be executed the braces are adj usted in their foot-rests with said rods D similarly connected to the levers; but the lift is increased by shifting said rods the other Way-that is, from the hands and toward the standards E.
It will also be seen that with the parts of one side of the platform adjusted for lifting and those of the other side for bearing down- Ward the operator may exercise in that man- 11er also, and when he desires the parallel-bar exercise he has only to adj ust the braces J in their rests and engage the hooks R with the lugs S.
The foot-rests for the braces J consist of metal sockets attached tothe side ofthe standards, into which the lower ends, T, enter to the shoulder W in sufficient length to prevent their disconnection by any shocks or thrusts to which they may be subject in the parallel-bar exercise.
The braces J may be modied according to circumstances. For instance, if the fulcrum standards be extended upward a little above the pivots I, said braces may take the form of suspending hooks or links, and I do not limit myself to the particular arrangement shown.
The levers or handles of this machine are pivoted upon uprights about as high or a littlc higher above the platform as the hands of a man ot average height when standing upright on the platform, so that they range horizontally, or thereabout, when held in the hands by a person at rest, instead of rising up vertically to the hands of the operator as in most other machines. This avoids the necessity of any vertical adjusting devices to the handle for men of different heights, becausethe handles may be held a little above or below the horizontal position, according as the operator is tall or short; and another advantage is, the leverage may be varied without any change of the apparatus by simply changing the distance of the operator toward or from the fulcrumstandards.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s
l. The combination, in an exercisingmachine, ofa platform, connecting-rods, and working-levers, said working-levers being coupled to the fulcrum -supports by duplex pivotal connections, arranged for readily shifting the fulcrnm from one side to the other of said platform, and connecting-rods to enable the operator to raise said platform, either by lifting up or pressing down on said levers, substantially as described.
2. The combination, in an exercising-machine, of theplatform, working-levers, and connecting-rods, in an arrangement by which the operator may raise the plat-form by simultaneously lifting on one lever and pressing down on the other, substantially as described.
3. The combination, in an exercisingdna chine, of a platform, connecting-rods, and a pair of levers, and devices for raising the platform by lifting on said levers, and also devices whereby said machineis convertibleinto an arrangement for raising said platform by lifting on one of said levers and pressingr down on the other, substantially as described.
4. The combination, with the platform, connecting-rods, working-levers, and fulcrumstandards of an exercising-machine, of the coupling-links H and braces J, said braces having a detachable l'ootrest, substantially as described.
5. The combination, with platform B, connecting-rods D, working-levers E, connecting links H, and braces J, of the hooks R, substantially as described.
6. The combination, in an exercising-machine, of the platform, lever-standards, connecting-rods, and working-levers, said levers being pivoted on said standards at a point about as high as the hands of the operator when standing at rest on the platform,and ranging horizontally, or thereabout, from said standards to the hands of the operator, substantially as described.
