MOTOR FOR COIN-CONTROLLED APPARATUS.

SPECIFICATION forming part of Letters .Patent No. 692,965, dated February 11, 1902.

Application filed February 2l, 1901. Serial No. 48,282. (No model.)

To all whom it may concern.-

Beit known that LCHARLES ALBERT YALE, a citizen of the United States, residing at Burlington, in the county of Chittenden and State of Vermont, have invented certain new and useful Improvements in Motors for Coin-Controlled Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable othro ers skilled inthe art to Whichit appertains to make and use the same.

'My invention relates to motors particularly designed for use in coin-controlled apparatus, but which may be used for other purposes;

and the objects of the same are to simplify the construction and to render-the mechanism reliable and efficient in operation and not liable to get out of order.

Another object is to simplify the winding 2o mechanism in motors of this character and to provide means whereby the motor may be Wound up quickly Without a lever or key. y Y Still another object is to provide means for giving a smooth reliable movement to the Weight used for operating the motor and to provide an automatic gravity clamp or clutch for the Winding-cordwhich will permit Vthe cord to pass freelythrongh it in one direction and to clamp it firmly against movement in 3o the opposite direction. l

AThese objects are attained bymeans of the construction ill nsti-ated in the accompanying drawings, in Which-- Figure 1 is a rear elevation of the upper portion of a cabinet or casing of a coin-controlled apparatus,the back board or door of the cabinet being removed to better illustrate the interior mechanism. Fig. 2 is a plan View of the motor. Fig. 3 is a vertical lon- 4o gitudinal section on the line oxo, Fig. 2. Fig. 4 is a detail elevation of the friction-disks and the intermediate disk or Wheel. Fig. 5 is a perspective view of the end of the rope-clamp.

Like characters of reference designate like 4 5 parts Wherever they occur in views of the drawings.

Referring to Fig. 1 of the drawings, the

numeral 1 designates a cabinet or casing containing the mechanism of a coin-controlled the different apparatus. The numeral 2 designates the 5o motor which is made the subject of this application, and 3 is a delivery mechanism or an ejector for small packages of goods or for tickets representing goods. This delivery mechanism is m'ade the subject of a separate 55 application for Letters Patent tiled by me February 2l, 1901, and bearing Serial No. 48,281. It will be understood, of course, that the motor herein described and disclosed maybe used in connection with mechanism of a dif- 6o ferent character from that shown in Fig. 1.

Referring now to Figs. 2 and 3 of the drawings, Which show the details of construction of the motor on a larger scale than is illusy trated'in Fig. 1, the numeral 4 designates a o5 Winding-drum consisting of a hollow cylinder having at one end a plain disk-head 5, rigidly secured thereto in any suitable manner, and at the opposite end a ratchet-wheel 6, also firmly secured to the cylinder or drum 7o 4. The axle 7 for this drum is secured rigidly at its ends in a rectangular frame 8, the axle passing freely through openings formed centrally in the disk 5 and in the ratchet-Wheel 6. Volve upon the axle and does not require the ends of the axle to be joui-naled in the framework. The end of the drum 4 adjacent the ratchet-Wheel 6 is dared outward, as at 4, to prevent the windingcord riding up onto 8o the ratchet-Wheel. The master-Wheel 9 has a hub 10 and is also mounted to revolve freely upon the axle 7. Two oppositely-disposed 'pawls l1 1la are pivoted to opposite spokes of the Wheel 9, and these paWls engage the teeth 85 of the ratchet-wheel G and are heldin operative position by the springs 12, each connected at one end to the pawl, Wound once around a stud 13, projected from one of the spokes of the Wheel 9, and the terminal end of the 9o spring being bent at right angles and secured in a hole in another spoke of the Wheel 9, as shown in Fig. 3. The cogs on thev periphery of the master-Wheel 9 mesh with the teeth on a pinion 14, rigidly fixed to a shaft 15, jour- 95 naled at its ends in the frame 8. Secured to the shaft 15, near the pinion 14, is a cam-disk 16, having a notch 17 and a stop 18. A face- This construction permits the drum to rev plate 19 is secured to the side of the cam-disk 16 by screws 20, and projecting outward from the face-plate is a stop 21, reference to which will be hereinafter made. Fixed to the shaft 15 are a pair of friction-disks 22, (see Fig. 4,) adjustably spaced apart by set-screws 23,

which pass through smooth holes in the outerk disk and engage threads in the holes in the inner disk, thus serving to adjust the disks at different distances apart for a purpose which will be hereinafter described.

Secured to the shaft 15, near its longitudinal center, is an eccentric 24, and fitted into a groove in this eccentric is a yoke 25, formed on'a rod 26, the terminal end of said rod being bent at right angles to connect with a portion of the delivery mechanism. A similar eccentric 27, fixed to the shaft 15, may he connected by a rod, like 26, to a register (not shown) for indicating the number of times the machine has been operated or the number of coins deposited in the apparatus. Journaled to revolve freely in brackets 28, depending from the frame 8, is a shaft 29, to

which is lfixed an insulated disk 30, said disk being beveled on opposite sides near its periphery and fitted between the friction-disks 22. A spring-brake 31, supported by an arm 32, projecting from the frame 8, bears against the periphery of the disk 30 to retard its revolution and to prevent the hand-shaft 29 from such a rapid revolution that the hand or pointer could not be seen as it traverses the dial.

It will be understood that the motor may be used in connection with electrically-operated mechanisms, and when thus utilized a pair of electromagnets 33 maybe supported upon a bracket 34, adjustably secured to the frame 8 by the screws 35, passing through slots 36 in said bracket. An armature 37 is pivoted at one end to a depending support 38 and extends over the magnets 33 in position to be Within their electric field. A spring 39 is secured at one end to the armature, and its other end is attached to an adjusting-screw 40, passing through a threaded opening in an arm 41, extending out from the bracket 34. A stop-pin 42, adjustable in the arm 4l, serves to limit the upward throw of the armature 37 when the current through the magnets is broken, the spring 39 then lifting the armature away from the magnets. The free end of the armature 37 serves as an abutment against the stop 21, and when the magnets 33 are energized the armature is attracted to them, and the abutting end thereof is moved out of the path of the stop 21, thus permitting the shaft 15 to revolve. A spring-brush 43 is secured at one end to an insulated block 44, mounted upon the arm 41. The free end of the brush 43 has a non-conducting block 45 secured to its under side, and this block bears upon the periphery of the notched disk 16. Four contact-points 46 are secured to the block 44, the free ends of said contactpoints being disposed above the brush 43,near

Vare included.

its outer end. The brushes 46 are connected to a conductor 46 and the spring 43 to a conductor 43, forming part of an electric circuit in which a batteryX and the electromagnet 33 The spring .43 forms the armature of an electromagnet 43h, placed in a circuit extending to contact-pieces y, adapted to be connected electrically by a coin @inserted in the machine, the result of this action being to energize the magnet 43", attracting the armature 43 to it, and Vthus raising the block 45 out of the notch 17 and permitting the stop 18 to pass under the brush as the disk 16 is revolved. lVhen the current is broken,the spring 43 carries the block 45 into the notch 17 at the same time the end of the armature 37 comes into the path of the stop 21.

A keyhole-slot 46n is formed in the drum 4, and a rope or cord 47, Fig. 1, has a knot or stop on its end, which is inserted into the larger part of the slot 46 and moved under the smaller portion of said slot to connect the cord or rope to the drum. This cord or rope passes up over pulleys 48 near the upper portion of the cabinet 1 and. down to a weight 49. This Weight maybe of rectangular form, and a hole is formed in each side or at each diagonal corn erlongitudinally thereof to form a guideway for two vertical rods 50, secured at their ends to the cabinet 1. By this means the Weight moves smoothly up or down in performing its functions and is held in a substantially firm position for shipping. For Winding up the motor or for raising the Weight 49 an endless rope or cord 51 is used, and this rope or cord is once passed around the drum 4, the upper strand of the cord passing up over a pulley 527 and thence laterallyy over pulley 53 and out through the cabinet, down and around pulley 54,-through an opening in the cabinet and under the pulley 55, and back to the drum.

The pulley 55 is journaled in a strong spring-yoke 56, one end of Which is securedto the cabinet and the free end'carrying the pulley 55. The yoke 56 exerts sufficient pressure downward upon the pulley 55 to always keep the rope 51 taut. When it is desired to wind up the motor, the portion of the cord 51 outside the cabinet is grasped and pulled downward, thus winding the cord 47Yon the drum 4 and raising the .weight 49. To prevent a backward movement of the drum after each pull upon the rope 51, an automatic rope clamp or clutch 57 is employed. This clamp consists of a bracket secured to the framework of the cabinet and extending. out into the path ofthe cord 51.v The outer end of the bracket is grooved, as at 58, and a clamp 59 is pivoted at 60 to the outer end of the bracket. When the cord 5l is pulled in the direction necessary to wind up the Weight, it passes readily through between the outer end of the bracket and the clamp. A pull inthe opposite direction throws oneedge of the kclamp 59 against the rope and prevents the rope from a backward movement.

It will be understood that when the weight 49 descends the drum 4 revolves within the loop of rope 5l, the clamp 57 holding said rope against a downward movement at that point.

The operation of the motor may be described as follows: It will be understood that if the dierent mechanisms are to he operated by electricity the proper connections will be made to start the motor when a coin has been deposited in a coin-tube. When the motor is at rest, the block 45 is seated in the notch 17 in the disk 16, and the end of the armature 37 is in contact with the stop 2l. Then a coin, as z, is inserted in the machine, an electric circuit is established through the electromagnot 43", the armature 43 is attracted, and block 45 is lifted ont of the notch 17. Atthe same timethe contacts4346 are brought together, establishing a circuit through the electromagnet 33 and causing its armature 37 to be attracted out of the path of the stop 21. The weight 49 then moves downward on the guide-rods 50, revolving the drum 4, and thus starting the various mechanisms which may be inclosed within the cabinet 1. When the weight 49 moves downward, the rope 5l,which is passed once around the drum 4, is held firmly by the clamp 57, and since the friction of the rope at the point where it surrounds the drum is not sufficient to overcome the force of the weight 49 when released the drum slips within the loop of said rope. Ahand or pointer may be secured to the shaft 29, and as the motor moves an initial impetusis given to said shaft, and the disk 30 is revolved between the friction-disks 22 until the hand cornes to a stop. When the disk 16 has made one revolution and current has been broken, the armature 37 is raised by the spring 39 and comes into contact with the stop 21, the block 45 then dropping into the notch 17 by means of the normal stress of 'the spring 43.
