SPECIFICATION forming part of Letters Patent No. 445,618, dated February 3, 1891.

Application filed March 13, 1890- Serial No. 343,711. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK WILLIAM ZIMER, a subject of the Emperor of Germany, residing at London, England, have invented an Improved Combined Treadle and Hand Driving or Actuating Mechanism, of which the following is a full, clear, and exact description.

This invention relates to improved com bined treadle and hand driving mechanism, which may be applied and used as means for propelling bicycles and other vehicles and boats and for imparting motion to or actuating machinery of various kinds.

The special object of the invention is to economize and utilize to the best advantage for the purpose required the whole available weight and lifting-power which man can bring into operation at a time; and to this end the invention consists in so constructing and arranging such mechanism as that the weight and whole lifting-power of the operator exerted in directly opposite vertical or nearly vertical directions practically in a line with the direction of the body are conjunctively utilized in the manner and by the means hereinafter described by causing him at each actuation of the mechanism to simultaneously depress one of a pair of treadle or like footoperated devices and lift by both hands a double handle-bar, each directly or-indirectly operating on the shaft, levers, or connected mechanism to be actuated, hereinafter referred to as the said shaft or connected mechanism; in consequence of which combined simultaneous and opposite directions of his cnergyh-e can exert a considerably increased effective power over that he could exert and can. obtain and impart a more uniform or continuous motion than he could ob tain and impart with any, existing combined hand and treadle driving or actuating appliances, as at the time of his exerting such energy there is added to his weight the whole lifting-power he is capable of exerting, as well as the additional momentum which the e xercise of such lifting-power causes to be thrown onto such foot operating devices.

The improved mechanism is illustrated on the accompanying drawings as applied to a velocipede.

Figure 1 represents a side elevation of part of the vehicle with the improved mechanism applied thereto. Fig. 2 represents an elevation, partly in section, on an enlarged scale, of the hand operating mechanism; and Fig. 3 represents a plan view of part thereof.

4 represents a double handlebar, which is formed with handles occupying a relatively low position in the line of the body of the operator when operating the mechanism, and which is mounted in atubular boss 5 in such a manner that by the vertical or approximately vertical movements of the hands in a line with the body it can be reciprocated about its axis which passes through the boss, and such movements are, as hereinafter described, caused to be effective in aiding in actuating the said shaft or connected mechanism, which is represented in the illustration given by the shaft 40. The boss is made fast to a tube 7, rising from the fork 8, so that turning movements of the handle-bar about the axis of the tube will cause the vehicle or apparatus to which the improved mechanism is applied to be steered or directed according to such movements of the handle-bar. Adjacent to each side of the boss thereis made fast to the axial part of the handle-bar a tubular boss 9, to the two of which bosses the ends of a segmen tal bar 11 are secured, with the bar concentric with the intersection of the axis of the handle-bar with the axis of the tube 7. The tube 7 is encircled by and works within a tube 12, which is made fast to the backbone 13 of the machine, and has made fast to its upper end a tubular collar 1%, formed with projecting lugs 15, on which are fulcrumed rearwardly-projccting levers 16, which are con nccted by cross-bars 17 and 18, one of which is connected by a link 19 to the bar ll, and the other of which is connected by rods 20 to the said shaft or connected mechanism. The concentric disposition of the bar 11 allows of the vehicle or apparatus to which the improved incchanism is adapted being steered or directed by the turning of the handle-bar about the axis of the tube 7 without interfering with the connection of the handle-bar by the rods 20 or any equivalent connections with the said shaft or connected mechanism.

21 represents a tubular collar, which is loosely mounted on the tube 7 and can be turned about the axisthereof to a limited extent. It is normally kept by a spring and stopping devices 23, respectively, connected to it and to the collar 14, in such a position as will cause projecting rests 2a, with which it is provided, to support the handle-bar in the position indicated in Fig.-2,and will then only allow of the handle-bar being reciprocated above such supported position in actuating the said shaft or connected mechanism. The collar 2.1. can, however, by a connected pull-rod 25, bell-crank 26, and chain 27, actuated by the pull of a finger or by any other suitable means,'be turned about the axis of the tube 7 from such supporting position toa position in which it will cease to support the handle-bar, and will allow of the latter being lowered below its normally-supported position, in which event it will be operative in applying the brake 28 to the front wheel 29, (ride) Fig. 2; or by means of suitable connections 30, it may also be operative in applying a brake on a rear wheel or wheels or on any convenient part of the vehicle or apparatus to which the mechanism is applied. The handle-bar is caused to be operative in such manner at such times by means of adj ustable rods 31, which are screwed into the bosses 9 through its axis, and consequently partake of the said Vertical reciprocations, but reversely being on the opposite side of such axis. XV hen the collar 21 is turned about its axis, as aforesaid, and the handle-bar is depressed below its said supported position, the circumferentially-grooved ends of the rods 31 engage with the projecting ends of a cross-rod which is supported by arms 33, projecting from loosely-mounted collars 34c, encircling adjacent turn ed parts of the boss 5 or of the bosses 5 and 9, and is connected bya dependingrod 35 to the brake 28, centered at 30 to a bearing 37, projecting from the fork, and such brake and any connected brake is or are consequently applied and can be applied with the whole weight of the upper part of the body of the operator bearing 011 the handlebar, which is a considerable advantage. The cross-rod 32 and the brake 28 are normally kept in position ready for such actuation by a spring 38, connected to a cross-bar 39 and to the boss 5. The said vertical lifting movements of the handle-bar are rendered effective in actuating the said shaft or connected mechanism, as aforesaid, by connecting the rods 20 or any equivalent connecting means thereto by a clutch-operating device, by a ratchet and pawl, by levers, or by any suitable means which will allow of the unimpeded lowering of the handle-bar after each actuation for the next following operation. Such device in the illustration given is represented by a recessed clutch 42', which is caused to be reciprocated about the axis of the shaft 40 by the movements of the rods 20. The clutch surrounds the hub 43 of the shaft and'is formed with inclined recesses 44, fitted with rollers 45, of a less diameter than the greatest depth of the recesses, so that as the clutch is reversed by the lowering of the handle-bar the rollers 45 will freely follow and will not interfere with the turning of the shaft by the operation of the pedals 6, (which at any time may alone be operated if the operator desires to rest on the handle-bar in its supported position but when the clutch is brought into operation at each lifting operation of the handle-bar the rollers 45 are jammed between it and the hub of the shaft, and the lifting-power of the operator is thus utilized. If the motion of the shaft 40 be desired to be communicated to any other axle of the vehicle or apparatus to which the mechanism is applied, such may be effected by a chain-wheel 46 and connecting-chains 47 or by bevel-gearing or in any other convenient or appropriate manner, and by such means motion may be given, for example, to a paddle or screw-propeller shaft or to the axle of a grindstone. The lateral turning of the handle-bar may belikewise utilized for steering or guiding purposes by suitably connecting it to the rudder attachments or to the part to be actuated, and the braking movement of the handle-bar may likewise be utilized in stopping or reversing the paddles or in disconnecting the gearing. The vertical reciprocations of the handle-bar may also be utilized for steering or directing purposes, in like manner as hereinbefore described with reference to the utilization of such movements for braking purposes. It will be seen that in the hereinbefore-described improved arrangement the total lifting-power of both hands exerted in the line of the body is applied at each actuation of the handle-bar simultaneously with the depression of each treadle.

In the hereinbefore-described arrangement the clutch-operating device is actuated directly by the upward pull of the handle-bar, as aforesaid; but the said lifting-power may be indirectly applied by causing it to compress a spring 48, linked to the clutch, and to simultaneously raise the latter into operative position, so that on the handle-barbeing low ered the required energy of the spring will be operative in actuating the clutch.

I am aware that it is not novel to use the hands and feet conjunctively and simultaneously in driving mechanism or the like, and that various arrangements of combined treadle and hand driving mechanism now exist, in some of which the hands and feet are conjunetively and simultaneously used in horizontally, or approximately so, p ushing an d pulling in reverse directions connected hand and pedal levers in which the weight or gravity of the operator is not to any material extent utilized; in another of which arrangements the hands alternately pull up independent pivoted hand-levers respectively permanently connected to and giving a downward thrust to pedal-levers upon which one of the feet simultaneously acts also with a downward thrust, and in another of which a forwardly-placed pivoted handle is oscillated by the forwardly-extended hand or hands so as to aid by its connection to clutches on the pedal-shaft in the driving or propelling operation, and I lay no claim to any such arrangements.
