PLATFORM-MOTOR FOR PHONOGRAPHS, 80C.
SPECIFICATION forming part of Letters Patent 0. 680,060, dated August 6, 1901.
Application filed April 26, 1898. Serial No. 678,835. (No model.)
To all whom, it may concern:
Be it known that. I, WALTER H. MILLER,
a citizen of the United States, residing atv Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Platform-Motors for Phonographs, &c.; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to whichit'appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.
This invention relates to that class of motors in which the weight of the human body is utilized as the motive force.
The improvement is applicable more especially to phonographs, although it may be ience involved in changing the position of the body to accommodate it to the change in the position of said platform.
Other advantages and results may be referred to hereinafter in connection with the description of the working parts.
The invention consists in the improved motor for phonographs, &c., and in the arrangements and combinations of parts of the same,
all substantially as will be hereinafter set forth and finally embraced in the clauses of the claim.
Referring to the accompanying drawings, in which like characters of reference indicate corresponding parts in each of the several views, Figure 1 is a front elevation of my improved motor applied to a phonograph, the front portion of the inclosiug case being removed to more fully show the operating mechanism. Fig. 2 is a side elevation of the same. Fig. 3 is a detail side view showing certain rear connections with a platform-supporting lever. Fig. 4 is a detail plan of the same. Figs. 5 and 6 are detail views of a certain catch or detent lever, and Figs. 7 and 8 are detail views of another lever connected therewith. Fig. 9 is a detail side view of certain holding mechanisms for preventing the train of motor-gearing from operating. Fig. lOis a front view of certain releasing mechanisms, and Fig. 11 is a plan of therear end of the platform-lever.
In said drawings, a indicates a suitable case'having at its lower part an extension which is open at the front to permit the d0wnward movement of a horizontal platform I), upon which the person whose weight gives motion to the machine stands whilelisteningto the sound issuing from the phonograph. The said platform I) is vertically movable while maintaining its horizontal position and has no material pivotal movement by which it would be caused to pitch or incline backward or forward to the inconvenience of the listener. While in the construction shown said platform has a slight forward movement as it lowers, this is not suflicient in degree to be inconvenient, if at all noticeable, and for all practical purposes the movement is vertical and is so denominated herein. platform I) is supported at its forward end by a lever or levers c, fulcrumed at d upon suitable bearings a, formed at the base of the case, the said bearings being preferably provided with balls, by means of which friction is reduced, the ball-bearings being applied in any suitable manner. At its rear end the platform is supported by connections with said lever, as hereinafter described. The lever 0 preferably comprises a shaft, to which are secured three upwardly-inclined arms, of which the forward arms 0 extend to the front part of the platform 1) near the opposite ends thereof and the rear arm 0. extends rearward for purposes hereinafter specified. The said lever-arms c" are pivoted, as atf, to the under side of the said platform. Suitable ears or extensions f are provided to receive the same. A regulating screw or screws f may be employed to limit the downward movement of said arms. The rear edge of the platform lies back of the vertical front face or board a of the case, as indicated in Fig. 2,and is supported by a chain orflexible connection d of sufficient strength and little or no extensibility, which is secured to said platform The said IOO ' when the parts arein the relation shown at' about midway between the ends thereof and j. Said door serves to close the opening or aperture formed by the descending platform, supplementing the front plate of the case and preventing the entrance of dust or dirt and improper access to the working parts within.
The chain (1 and the-lever 0 thus cooperatein holding the platform at a horizontal position and inasmuch as the front and rear arms of the lever are of about equal length the chain at its connection with the platform lowers with the same rate of speed as the forward arm of the lever'lowers, and thus the horizontal position of the platform is maintained as it descends under the weightof the listener.
Suitable means are provided within the casing for holding the platform up to its high est position when not properly in use or for preventing the downward'movement of said platform prior to its being released by the insertion of a coin, the price of a hearing at the machine, and the release of the holding mechanism. Means are provided for releasing said holding devices and permitting the insertion of the coin into the machine and guiding and controlling its movements to the releasing devices. ranged a bed-plate or frame K, which is preferably removable from the casing, said frame being provided with inward ly-projecting ears or flanges k k', as shown in'Figs. 1 and 2, which ears or flanges afiord bearings for a series of arbors or shafts and other appliances. of a train of mechanism controlled by the downward movements of the platform.
From the idle pulley h, Fig. 2, the chain (1 extends downward to the lever-arm c, and from thence it passes under the sprocketwheel Z, arranged on the arbor m, and i'm parting motion to said sprocket-wheel and the parts in train therewith. From said sprocketwheel said chain extends upward and connects with a cord of twisted wire 61, which latter passes over a pulley n, arranged near the top of the machine, and from thence downward to a Weight 0 for counterbalancing the weight of the platform. Of course it will be understood that the chain can easily'be continued over the pulley n' and down to the weight.
I prefer to employ an idle pulley n, Fig. 2,
a point below the phonograph to press said belt or chain cl back out of engagement or \Vithin said casing is armally in an elevated position.
cylinder to permit a slow outflow of air, so 7 that the downward progress of said weight when the platform is free of the weight of the listener is retarded and there will be no sudden movements detrimental to the machine and productive of noise. The air cush ion also prevents the platform from tripping or throwing the auditor as he steps off be cause of a quick upward action when said platform is relieved of weight.
The actions of the air-cushion and plat form when the parts are constructed as de scribed are thus extended over a considerable period of time, beginning immediately upon the stepping off of the listener and continuing during the whole period of descent of the weight and the return of the platform to its elevated position. Thus the raising of the platform is slow and regular and without any jarring action, as above described.
To maintain the desired horizontal position of the platform during its descent, l connect the rear end of the arm a of the lever c to the lower rear end of the chain d,as shown in Fig. 2, by which means the chain and the lever are compelled to move together simultaneously and the distance of movement of the chain will be substantially equal to the distance of movement of the forward end of the lever c where it connects to the platform, the arms of said lever being substantially of the same length, as above indicated, or the point of connection of the platform with one arm of the lever and of the chain .Withthe other arm of the lever being of uniform distance from the fulcrumal bearing of the lever, as will be understood. The chain d in the construction shown is discontinuous at the arm 0 or the said arm 0 forms one of the links thereof; but it is understood that other means may be employed for extending the maintaining its horizontal relation other than these specifically described.
It will be understood from the above description that the
weight 19, acting both on the chain and lever, holds the platform nor- To lock the platform in this elevated position and prevent the machine being worked prior to the insertion of a coin, I provide a detent or stop mechanism of any suitable construction. The construction shown and described is the one I prefer to employ and desire particularly to claim. Said preferred construction includes a stop-bar q for operating a pawl s est limit of movement.
and preventing the working parts from moving. Said bar q is engaged near its lower end by a friction-clip attached to the rear end or arm 0 of the lever c, the said bar q extending downward between the spring q" and the extension q formed or secured at the rear end of said arm 0, as will be understood upon reference to Figs. 3, 9,and 11. By this construction the arm a of the lever c is movable independent of the stop-bar q and is capableof clutching and operating said bar q to effect an engagement of the pawl s with the ratchet-wheel i when said pawl is free to be thus operated.
When the platform lowers and the lever c lifts the bar q longitudinally, the pawl-lever s, Fig. 9, is turned on its fulcrum and the pawl-tooth r is thrown out of engagement with the ratchet -wheelt. In the reverse movement of the platform the pawl is brought into holding relation with the said
ratchetwheel 25 with an elastic pressure due to the spring 0", Fig. 9, and the devices in train with said ratchet-wheel are prevented from rotation, the friction clip or clutch attached to the lever c is permitted to slide on the bar q, the propelling power overcoming the clutchfriction of the contact, and the said lever 0 thus continues its movement until the up ward-moving platform I) arrives at its high- By this construction and arrangement of parts it will be apparent that the machineis locked by the engagement of the locking-pawl with the Wheel t of the train of gearing immediately upon the removal of the weight of the listener from the platform and the beginning of the return movement impelled by the weight 0. Said platform is returned to its initial position, even though the auditor has not waited to listen to the full complement of music paid for and the speaker of the phonograph has not traversed the full length of the cylinder.
The ratchet or gear wheel 15, as above indicated, is in train with the series of gear or cog wheels Z, Z F, to Z, by means of which the motion of the weighted platform and its supporting-chain is transmitted to.the phonograph and governor Z", the wheel or pinion L" transmitting the power to the governor in any suitable manner. The pawllever 8, connected to the upper end of the stop-rod q, is fulcrumed at 8 upon the frame of the machine or one of the flanges 10'' thereof, and at its end opposite that at which it is pivotally connected to said rod (1 it is provided with the pawl comprising a spring rand the pawltooth r, Fig. 9, as above mentioned. When said rod q is forced upward by the frictionclip above described, upon the descent of the platform, the said tooth 0" will be thrown out of engagement with the wheel 15, and the said wheel 15 and the cogwheels Z Z Z &c., above referred to, in train therewith will be free to revolve and to transmit motion'from the descending platform to the phonograph or other mechanism to be operated, as will be said cog-wheels may be varied at will.
The lower extremity of the stop-rod q is somewhat reduced in diameter, so that at the initial point of release the frictionclip will not be hard thereon, thus reducing the amount of power required to secure the release of the pawl 3' under the weight of the coin. This reduction of the rod is, however, but slight and not observable in the drawings and may be omitted in the construction. To release the stop rod or bar and its pawl from .holding engagement with the train of power transmitting devices, I have employed mechanism controlled by the weight of a coin inserted in the machine as the price of a hearing.
Any releasing device may be employed; but the device preferred 1 have shown and I will now proceed to describe.
Upon the mounting of the platform by the auditor and the insertion of the coin within the slot of the inclosing case a in any 0rdi-' nary manner the coin is directed by means of a curved guideway u to a trip-lever '12, referring especially to Fig. 1, the point of engagement of said lever by the coin being somewhat cup-shaped to receive the coin from the guideway and after the descent of one arm '0 of the trip-lever to direct it into the coin-receptacle w, the downward movements of said arm 2; being limited by a suitable stop. (Not shown.) The said lever 'u is held in a normal position to receive the coin from the slideway by a weight 0], Fig. 1, arranged on a third arm of said lever, or a spring may be employed for the same purpose. The
arm 12 of said lever o serves as a stop or keeper for another lever 3, loosely fulcrumed at one end, as at 4, upon the forward edge of one of the flanges of the frame. This loose lever 3 crosses the plane of action of the pawl-lever s, so as to lie in contact with the upper edge of the said pawl-lever s, as shown in Fig. 9. Thus when said arm 0" is in holding relation to said lever 3 the latter is held transversely across the plane of action of the lever s and serves as a stop or holding device for the same. The free end of said loose lever 3 is arranged within a guideway 4, Fig. 2, having a slot 5, adapted to contain and guide the said free end of the lever 3. This slot 5 is so formed and related in position to the lever 3 and the arm r' of the lever '0 that it will direct or guide the loose lever 3, when released and pushed up by the pawl-lever s, obliquely upward and outward from under the lifted downwardly-extending end of the arm '0'. Conversely, when the loose lever 3 is permitted to gravitate by the downward movement of the rod q and pawl-lever arm connected thereto it will be guided to a position beneath the end of the arm 71, and thus locked again, all as will be understood.
Upon the frame of the machine, contiguous to the pawl-lever s, is fulcrumed, as at 6, Fig. 10, a walking-
beam 7, which is linked by the rod or link 8 to the pawl-lever s. The op posite end of the walking- beam 7 is connected by a rod 9 to a spring-lever 10, fulcrumed at 11 upon a bracket or stud 12, connected to or formed upon the bottom of the casing of the machine. Said spring-lever comprises, preferably, an arm of rigid metal 13, to which is fastened a flat steel spring 14:. The lower extremityof the said rod 8 is threaded and enters a correspondingly threaded perforation in the rigid portion 13 of the said spring-lever 10. The spring portion 14 of said spring-lever is held to the rigid portion 13 by any suitable means,and the said spring portion extends forward to a point of engagement with the leverarm 0. When the said arm a is brought to its lowest limit of movement, it engages the end of said spring-arm 10 and depresses the same against the elasticity of the spring portion 14:. The result of this is to cause a tension upon the rod 9, the connecting rod or link 8, and
the pawl-lever s, which tends to throw the pawl-tooth r from holding engagement with the cog or
gear wheel 25. Said pawl-lever is, however, held from moving by the lever 3 and trip-lever o, as above described. As soon as a coin acts upon the trip-lever o, thereby releasing the loose lever 3, the spring-lever 10 resumes its normal straight position by Virtue of its elasticity, producing a downward draft on the rod 9 and an upward draft on the connecting-rod 8, and thus throwing the pawl tooth r from engagement with the cog or gear Wheel t and sliding the stop-rod q upward in relation to the friction-clip against the fric-x tion thereof. The weight of the coin thus eifects a train of movement by which the pawltooth r is Withdrawn from holding relation to the train of transmitting gear-Wheels as soon as a coin is inserted in the machine and without waiting for the upward movement of the arm 0 to begin.
To facilitate the starting of the machine, so as to secure a movement more immediate than the weight of the body alone acting through the train of devices would produce,l have provided a push-
pawl 35, Figs. 3 and 4, which is adapted to engage one of the wheels of the train of power-transmitting gearing to facilitate a forward operation thereof. Said push-pawl may engage any one of the said wheels to secure the desired operation. The said pushpawl is hinged at one arm 361 of a bell- crank lever 36, fastened upon a shaft 37', said arm 361 extending to a point adjacent to the cogwheel and the push-pawl being held in operative position in a straight line with the said arm by a spring 351, which permits the cogs of the wheel to pass said pawl in their forward motion, the said hinge-joint permitting flexion of the pawl in only the one direction from its normal position in straight line with the arm 361. To another arm 362 of'the said bell-crank lever 36 is attached a power- storage spring 38, in which power may be stored as the platform ascends andthe lever-arm c descends. To effect this storage of power, the bell- crank lever 36 has an outwardly-extending third arm 363, and at a suitable point on the lever-arm .c' is pivoted a catch- piece 40, hooked at its upper end, as shown in Figs. 3 and 4. Upon the elevation of the lever-arm c to or nearly toits highest point the said catch- piece 40 engages with its upper hooked end the third arm 363 of the bell- crank lever 36, being held from slipping therefrom by the spring 39 acting on the projection 401 of the catch-piece. It will thus be seen that as the lever-arm c is depressed by the power of the counterbalancing-weight 0 it pulls down with it the third arm 363 of the bell- crank lever 36, thus turning the said bell-crank lever on its fulcrum and producing a tension in the spring 38. Near the lower limit of movement of the lever-arm c the said projection 401 strikes an adjustable stop t5, the catch 40 is released from the arm 41 of said lever 36, and the spring 38 becomes free to exert its power upon said bell-crank lever to cause the pawl 35 to push upon the gearwheel. This power becomes effective immediately upon the entrance of a coin and the consequent releasing of the machinery,
as has been described, and is expended in pushing the gear-wheel of the train to facilitate initial movements.
By the construction thus described the pro posed listener at the machine is enabled to step upon the level platform, insert the coin to release the mechanisms, and immediately listen to the sound issuing from said machine and during such listening maintain himself in easy position without any inconvenience or disturbance of his equilibrium or poise due to a change in inclination of the platform.
Adjacent to the sprocket-wheel Z, loose upon the shaft m, is a'ratchet-wheel 41, keyed to said shaft, said ratchet-wheel being engaged by
pawls 42 42, arranged on the side of the sprocket-wheel l and which produce rotation of the shaft and gear-wheels thereon during the upward movement of the lever-arm 0',
but allow said shaft to remain stationary during the-downward movement of the lever-arm, as is common in machinery.
