JOHN B. MILLER, OF MOUNT VERNON, OHIO.

COIN-CONTROLLED APPARATUS.

SPECIFICATION forming part of Letters Patent No. 512,205, dated January 2, 1894.

Application filed May 1, 1893. Serial No. 472,535- (No model.)

To all whom it may concern:

Be it known that I, JOHN B. MILLER, a citizen of the United States, residing at Mount Vernon, in the county of Knox and State of Ohio, have invented certain new and useful Improvements in 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 others skilled in the art to which it appertains to make and use the same. a

My invention relates to a coin-controlled apparatus for testing the force of a blow eierted by the fist, and has for its object to provide novel means for rendering the machine inoperative until a coin of the proper denomination has been deposited upon which the apparatus is in proper condition to receive the impact of the blow, which, when delivered, automatically registers the force of the same upon a suitable indicator, and to these ends my invention consists in the novel construction, arrangement of parts hereinafter fully described and afterward definitely pointed out in the claims following, due reference being had to the accompanying drawings forming a part of this specification, wherein Figure 1 is a front elevation of my improved machine; Fig. 2 a vertical section thereof, and Fig. 3, a front elevation, partly in section, the front of the casing being removed. Referring to the drawings the letter A indicates the casing of the machine provided in its upper front portion with a glass or other transparent pane B, through which may be viewed the indicator dial hereinafter described. In the lower portion of said casing is arranged a locked drawer G adapted to receive the coins.

D indicates astriking pad disposed within a suitable aperture a in the lower front portion of the casing and is designed to receive the impact of the blow. Said pad is rigidly affixed to one end of a hollow sleeve E which at its outer end fits over a block or plug F.

Between the front end of the sleeve E and plug F is disposed a stiff spiral spring G which exerts its force to press the pad D outward. In order that the tension of the spring may be adjusted a headed bolt H is centrally passed through the hollow sleeve E and plug F to the rear of the casing where it is provided with an adjusting nut g. The head end 9 of thebolt H is seated in a recess a in the forward end of the sleeve E, and byscrewing up the nut g the tension of the spring G will be increased in a manner apparent, thus rendering it necessary to deliver a more forcible blow upon the pad D to register a given amount upon the indicator.

I indicates a reciprocating rack mounted insuitalole bearings which gears with a pinion J, which in turn gears with a vertically movable rack K, and the upper end of the rack K gears with a pinion mounted on an arbor L carrying at its outer end an index hand M which is adapted to indicate upon a dial N the force of the blow delivered upon the pad D, in the manner hereinafter described.

0 indicates a coin chute of a proper size to receive a coin of the correct denomination to render the machine operative.

P indicates a lever pivoted between its ends in a bearing block p rigidly affixed to the sleeve E and is provided at one end with an inclined trough-shaped coin receptacle p; said lever being heaviest at the opposite end, whereby the lever will normally rest in the position shown in Fig.

Q indicates a push rod secured to the rear of the frame carrying the pad D, as clearly shown in Fig. 2, and adapted to freely pass within a hollow bore or longitudinal aperture formed in the rack I shown in dotted lines in said figure of drawings.

The operation of the machine as above described is as follows: Let it be supposed that the parts are in the positions shown, which are the positions which they normally occupy. Now if the pad D be struck a blow the force thereof will not be indicated upon the indicator N for the push rod Q will merely enter the hollow or tubular end of the rack I without moving the latter and consequently without operating the indicator mechanism. Now if a coin of the proper denomination be inserted in the chute O, it will drop down into the coin receptacle 1); thus rocking the lever P and swinging its end 19 up in front of the end of the rack I, the rocking movement of the lever being arrested or limited by an arm or stop R. If a blow be now delivered upon the pad D, the end of the lever P being interposed between the push-rod Q and rack I, said rack will be forced inward a distance equal to the distance traversed by the sleeve E and pad D against the tension of the spring G, and said rack will communicate its motion to the pinion J which in turn raises the rack K and rotates the index hand M, which indicates upon the dial the force exerted in delivering the blow upon the pad.

To hold the index hand atthe indicating pointl provide the following means. S indicates a bracket secured to the rear of the easingA and having rigidly secured thereto a strap T through which the rack K passes.

' springt is forced away from contact with the rack K which then drops by gravity and through the medium of the pinion J returns the rack I to its normal position. When a blow is delivered upon the pad D the jar communicates to the sleeve E, and consequently to the lever P and coin receptacle 19, serving to throw the coin out of said receptacle and permitting it to fall into the drawer O.

In order that the indicator may be accurately set at zero point I provide an adjusting screw Y tapped through a suitable bracket y,

the lower end of the rack K normally resting upon said screw and by means of which it may be vertically adjusted to cause the indicator to be accurately set at zero point. The chute O is made of such a size that itwill only admit coins of the proper size, and the lever P is so balanced that only a coin of sufficient weight will operate it.

As above constructed the parts need not be accurately constructed, as the tension of the spring G can at all times be very quickly and nicely adjusted as before described, and the indicator can with equal facility be accurately set when the parts are assembled, after which itsfurther adjustment will be unnecessary.

Having thus described my invention, what I claim is- 1. In a strength testing machine, the combination with a yielding pad carryinga push rod, a spring exerting a tension against said push rod and acting to operate an indicator,

of a rocking lever carrying at one end a coin receptacle which upon the reception of a coin causes said lever to cover the open end of said rack, substantially as described and for the purpose specified.

3. In a strength testing machine, the combination of the pad D and its hollow sleeve E, the spring G arranged therein, the pushrod Q carried by the pad frame, the rocking lever P provided in bearings on said sleeve and provided at one end with a coin receptacle p; and the hollow rack I acting to operate an indicator, substantially as described, whereby upon the insertion of .a coin the lever Poperates to close the open end of said rack, for the purpose specified.

4. In a strength testing machine, the com-' bination of the pad D and its hollow sleeve E, the spring G arranged therein, the push rod Q carried by the pad frame, the rocking lever P pivoted in bearings on said sleeve and provided at one end with a trough-shaped coin receptacle 19' the stop R, and the hollow rack 'I actuating an indicator, substantially as described, whereby upon the insertion of a coin the lever P operates to close the open end of said rack, for the purpose specified.

5. In a strength testing machine, the combination of the pad D and its hollow sleeve E, the spring G arranged therein, means for adjusting the tension of said spring, the push rodQ carried by the pad frame, the pad frame, the hollow rack I actuating an indicator, and coin controlled apparatus acting to close the open end of said rack upon the insertion of a coin, substantially as described and for the purpose specified.
