To all whom it may concern.-

Be it known that I, PEROIVAL Evnm'r'r, a subject of the Queen of Great Britain, residing at London, England, have invented new and useful Improvements in XVeighing-Machines, of which the following is a specification.-

My invention consists in a new kind of weighing-machine constructed in such manner that the act of placing a coin or the like in the apparatus will cause the weight of the body being weighed to be indicated on a dial or the like.

In order to carry out my invention, I construct my machine with a platform or other suitable device for receiving the body to be weighed, the platform communicating by any known arrangements of lever or levers with a counterpoise consisting of weights or springs, or weight and spring combined. I preferably use a weighted counterbalanced arm projecting from a pivoted spindle. The pivoted spindle,communicating by means of suitable mechanism with the platform, is caused to rotate on its axis when a body to be weighed is placed on the platform, and the said movement of the spindle will partly rotate the weighted arm until it counterbalances the body to be weighed. The weighted arm or equivalent counterpoise is provided with gearing or other suitable mechanism to operate an index inside the apparatus. The index may be made to move in a circular or other direction. Outside the apparatus I use an index, moving in a circular or other suitable direction, which, being attached to a gearing or other suitable mechanism inside the apparatus, is caused to move by the weight of a coin placed in a receptacle attached thereto. The movement of the outer index is regulated by a stop, which comes in contact with the index inside the apparatus. On the counterpoise reassuming its normal positiomwhieh is effected by the removal of the body being weighed, the indexes are moved back by the gearing or equivalent mechanism to their starting-point, and the receptacle for the coin is thereby brought into contact with a pin or catch, or

tacle and delivers the coin into a bag or box for receiving the same. If desired, in order to lessen the shock which would be caused by the counterpoise readily reassuming the normal position on the removal from the platform of the body being weighed, I employ a mechanism for retarding the same, which mechanism may consist of a iiy-escapement, or an air or other cushion consisting ofan arrangement of piston fitting loosely in a cylinder, so as to allow the gradual passage of air or other fluid; or any other equivalent device may be used for this purpose.

In order to enable my invention to be fully understood,l will proceed to describe the same by reference to the accompanying drawings, in which Figure l is a side elevation, partly in section, of a weighingmachine constructed according to my invention, and in which the weight ofa body being weighed is indicated on a dial. Fig. 2 is a front elevation with the lower part of the machine removed. Fig. 3 is a horizontal section on line A B of Fig. 1. Fig. 4 is a horizontal section on line C D of Fig. 6. Fig. 5 is a vertical section on line E F of Fig. 4, the lower part of the machine being removed. Fig. 6 is a vertical section on line G H of Fig. 5. Figs. 1, 2, and3are drawn to a scale of about onesixth full size, and Fig. 6 toabout one-third full size.

The same letters in all the figures represent the same or similar parts.

a is the platform of the machine, which is supported on knife-edges I), carried upon le ver frames o and d, which are suspended by means of hooks e from knife-edges e on these levers, and from knifeedges f, fixed to the frame 9 of the machine. The leverframed is similarly suspended on a knife-edge, d, by a hook, it, from the lever-frame c. The said means supporting the platform a are those usually employed in platform weighing-machines.

t is a lever or arm consisting. of an extension of the lever-frame c, and serving,by means of -the hooked lever or rod j and steel ribbon it,

other suitable device, which opens the recepl to connect the platform a with the counterpoise hereinafter described. The armi is pro- 1 is rotated by a coin dropped into the box d,

vided with a knife-edge,m,bearing in thelower or hooked end of the rodj.

Zis the weighted arm projecting from the pivoted spindle a, which arm Z, together with a weight, 0, forms the counterpoise of the platform a. A cord, 1), by which the weight 0 is suspended passes round a pulley, q, fixed on the spindlea. The steel ribbon k is attached to and wound upon the spindle n, so that when a weight is placed upon the platform a the said ribbon will partly rotate the spindle n and pulley q, and the weight 0 will be raised, and the weighted arm Z will partly rotate in the direction shown by the arrow until the weightsZ and ocounterbalance the body to be weighed.

r is a toothed quadrant fixed on the spindle a, and serving to operate, when the spindle is rotated, a pinion, s, fixed upon an arbor, t, which carries at one end the index bar or rod a. This bar is operated by the weight of the person on the platform, and regulates the extent of movement of the index o, andits function is to carry. back the stop Z in order to raise the box or receptacle d.

'0, Fig. 2, is the index, moving over a dial, w, placed outside the apparatus, which index serves to indicate the weight of the person or body being weighed. The arbor of the index ois shown at or. t is the arbor which carries the index bar or rod 'IZ. These arbors wand t carry at their inner ends, respectively, the stop Z and the bar a, and it will be seen by reference to Figs. 4 and 6 that the two arbors are distinct, otherwise the stop Z and bar or rod a could not act independently ofeach other. On

the arbor 00, Figs. 4 and 6, of the index 17 is fixed inside the apparatus a pinion, y, which gears with a quadrant, z, pivoted at a,and provided with a counter-weight, b.

To the quadrant z is attached an arm, 0, which carries the receptacle or box d for the coin h, and having an open top. The box d is normally situated immediately below a chute, 6', extending from a slit, f, in the frame or case 9 of the apparatus, as shown in Figs. 5 and 6. The box (Z is provided with a slit, 9, of a less extent or height than the diameter of the coin h whichis necessary to operate the mechanism. The chute e is formed with an opening, 6", in its bottom of such a size that anycoin smaller than the size of the predetermined coin will pass through the said opening into the apparatus without operating the U the index rod or bar it, inside the apparatus.

The stop Zis fixed ou the inner endof the thus overbalancing the weight b on the arm 0 and operating the quadrant z, the stop Z will rotate until its projection meets the bar a, when it will be stopped therebyat the proper position to indicate, by means of the outer index,v,the weight of the body upon the platform a. hen the weight is removed from the platform a, and the.weighted arm Z and weight 0 reassu me their normal positions, the bar a will in rotating bear against the stop Z, so as to again raise the receptacle or box d.

m is a finger or catch pivoted at a to the movable bottom i of box d in such a manner that when the box is depressed by the weight of the coin it placed therein the finger or catch an will, by coming in contact with the pin or catch 0 on the frame or case 9 of the machine, be caused to turn on its pivot 71. and pass by the pin 0. d is again raised by the removal of the weight from the platform a, the finger or catch m will again be brought into'contact with the pin 0, but will remain rigid, so as to cause the bottom 2" of the box or receptacle to open and deliver the coin into the bag 19 or other suitable receptacle.

q, Fig. 1, is the cylinder, in which fits loosely a piston (not necessary to be shown) connected by a rod, 1', to the pulley q. The said cylinder contains water or other suitable fluid, which. serves as a cushion, in order to lessen the shock on the weights Z and 0 reas snming their normal position when the weight is removed from the platform a.

8 is a fly on the arbor m, which also assists in retarding the movement of the mechanism and weights of the machine.

By this construction of weighing-machine, if a person place himself (or a body to be weighed be placed) on the platform a, the

spindle n will, by means of the arm a, rod j,

and steel ribbon k, be partly rotated, and the weight 0 will be thereby raised and the arm Z IIO rotated a certain distance, according to the weight of the person being weighed. This movement of rotation will be communicated to the bar a by means of the quadrant r and pinion s, the said extent of movement of bar a being practically that to which the index a will be subsequently moved to indicate the weight on the dial 20. If a coin of a predetermined size be now passed through the slit f, it will pass into the box or receptacle d, and by its weight will overbalance the arm 0. The arm a in falling will, by means of the quadrant z and pinion y, rotate the stop Z, together with the index 0 on the dial w, until the projection on the stop Z comes against the bar a, and the weight of the person on the platform a will be thus indicated on, the dial w. Upon the person stepping off the platform a the weights will resume their normal positions, and the bar a, as it is carried back by the mechanism, will carry with it it the stop .arbor as of the index 1;, and-when the pinion yf. Z, and the box or receptacle will be thereby raised, the bottom of the box d will be opened by the finger or catch at coming against the pin 0, and the coin h will be discharged into the bag 1). If a smaller coin than that predetermined should be dropped through the slitf, it would simply pass through the opening 6'' in the chute e into the bag 2) without operating the mechanism, and the slit f would of course be of such a size as would not admit of the introduction of a larger coin than that required.

Having now particularly described and ascertained the nature of my invention and in what manner the same is to be performed, I

declare that what I claim is 1. A weighing-machine having an aperture for receiving a coin, a weighted lever, a dial and index-hand, and intermediate mechanism connected with the same and whereby the coin, when deposited in the receiver, shall operate the lever and cause the hand to indicate the weight of the person or body being weighed.

2. In combination with a weighing-machine, substantially as described, the quadrant r, shaft 75, pinion 8, bar a, receptacle cl and its movable bottom, weighted arm 0, quadrant z, shaft :0, pinion y, stop Z, dial w, and index 11, substantially as shown and described.
