COIN-CONTROLLED STRENGTH-TESTING AND ADVERTISING MACHINE.

SPECIFICATION forming part of Letters Patent No. 428,821, dated May 27, 1890.

Application filed July 23, 1888- Serial No. 280,720. (No model.)

To all whom it may concern:

Be it known that I, IRVING A. WVATSON, a citizen of the United States, residing at (loncord, in the county of Merrimac and State of New Hampshire, have invented certain new and useful Improvements in Coin-Controlled Strength-Testing and Advertising- Machines, of which the following is a specification.

This invention relates to machines designed to test the pulling-power of a single finger.

The object of the invention is to provide such a machine with locking mechanism, which can only be released by the insertion of a coin and mechanism for registering the amount of force applied by means of a dial, and also mechanism for operating an advertising-plate, which shall display another or different advertisement at each pull, and a mechanism which shall also bring within reach of the operator an advertising check or com.

The invention consists in the combination of the several novel devices hereinafter described, and referred to in the claims, and fully illustrated in the accompanying drawings, forming a part of this specification, of which Figure 1 is afront elevation of the machine; Fig. 2, a vertical sectional elevation. Fig. 3 is a cross-section showing the rack and pin ion for rotating a shaft carrying at one end the registering-hand shown in Figs. 1 and 2, and also the ratchet-wheel and pawl and the coin-tube. Fig. 4 is a cross-section showing a train of gears for imparting motion to friction-Wheels by which the advertising-plate is operated. Fig. 5 is a cross-section showing the said friction-wheels. Fig. 6is a cross-section exposing the inner or back side of a notched pinion and pawl for limiting each movement of the advertising-plate. Fig. 7 is a cross-section of the friction-wheels mounted upon their respective shafts, shown in sectional elevation. Fig.8 shows the advertising-plate in elevation, upon which are shown the several spaces for advertisements. Fig. 9 is a sectional elevation, enlarged, showing a portion of the coin-tube, the locking and coin-dropping mechanism, and a portion of the supporting-frame. Fig. 10 is a broken A suitable case-A, inclosing the working parts, may be of any convenient design and formed either of wood or metal.

A vertical bed piece or frameB is provided with openings and ears or projections at various points for convenience in attaching the shafts and other parts of my improved mechanism, as will be hereinafter referred to.

A pull-bar 0 extends through the forward end of the case A and terminates in a hook c of convenient size to be grasped by a single finger of an operator, and upon this is mounted a spiral spring D. A bar E is suspended beneath and parallel with said pullbar and connected therewith only atits ends, the rear end of said suspended bar being formed into a circular collar 6 by reason of the connection of said bar E with the said pull-bar G, into which is fitted and secured the journal 0 of the pull-bar G. The said collar e is made a movable fit for a tube F, which incloses the pull-bar G and spiral spring D, the bottom of said tube being left open, as at f, to permit of the movement back and forth of the bar E and its collar 6 with any movement of said pull-bar. Metallic bearings F are secured by screws or otherwise to the case A for supporting each end of said tube F. The spring D is expanded between the forward bearing F and the said collar 6, as shown in Fig. 2. A lever Gr is pivoted at g to the frame B, and on its forward end is provided a pocket g for receiving a coin of any given denomination from the coin-tube H, which in the drawings is shown to extend thence to the top of the machine. The rear end of said lever G is made heavier than the forward or pocket end, so as to normally rest against the stop-piece e of the bar E, which prevents any movement of the pull-bar C.

To release the pull-bar from the lever G, a coin must be dropped into thetube H, whence it drops and lodges in the pocket g of said lever. The weight of the coin being sufficient to overbalanee the opposite end of the lever, the said end rises above the said step e and permits the pullbar to be drawn out, the spring D returning the same to its normal position. After a coin has been delivered into the pocket g and the opposite end of the lever G has risen above the stop a it so remains until an operator shall take the hook c and pull the bar C, a slight outward movement of which causes a trip-catch E, (see Fig. 2,) pivoted at c to the bar E, to come in contact with a hinged end g of the said pocket g, which, by aid of a spring g, normally holds a coin within the pocket g, but which, by contact with the forward-moving catch E, is made to increase the bottom opening in said pocket sufficiently to allow a coin to fall through. \Vhen the bar C shall have again returned to its normal position, the said lever G is permitted to return likewise. The catch E is held by gravity normally in contact with a stoppin e but when the bar E is moving backward the said catch is tripped by the end q sufficiently to allow the latter to pass over it.

A dial I is provided, and this may be graduated to pounds, as shown in Fig. 1, the number of pounds or form of graduation not be ing essential, however.

The registering mechanism consists of an indicator-hand 1', attached to the forward end of a shaft J, mounted within the frame 13, a pinion K, also mounted upon said shaft and meshing with a vertical rack L, carried upon a vertical rod or shaft Z, mounted in bearings 1), formed upon the bed or frame l3, and an inclined frame E secured to one side of the bar E and inclining downward from its forward end rearwardly, upon the under side of which bears a slide L, mounted upon the lower end of the vertical rod or shaft Z, a spiral spring Z being attached to an arm Z mounted upon said shaft Z and connected at b with the frame I The said rack L, after having been moved downward by means of the pull-bar C, the incline E and the slide L, attached to the lower end of the shaft Z, is returned to its normal position by said spring Z.

In order that the hand i may remain in the position to which it may be moved by an operator long enough to enable any one to accurately note the number of pounds which have been pulled, I mount upon the shaft J a ratchet-wheel M, containing as many teeth at as there are pounds graduated upon the dial 1, and upon the frame ll at any convenient point I pivot a pawl M, which shall e11- gage the teeth of the ratchetby the action of gravity, the said pawl being provided with an arm on, which enters a slot 71 in the coin-tube II, as seen in Figs. 2 and 3. This arm in receives the whole weight of a coin while it is passing downward through the tube, which removes the pawl M from the teeth m of the wheel M, which enables the pin m of the swinging arm M to support the heavy end of said pawl by reason of said swinging arms assuming a vertical position. A right-angled projection extending outward from the pivotal point of said arm M is struck by a pin 7, secured in the arm Z when the rack nears its upward limit of stroke, causing the arm M to move back to the position shown in the drawings, and permits the pawl M to again engage the teeth of the ratchet-wheel M.

I do not limit myself to any one means for holding the indicating-hand at a given figure upon the dial, however, as various mechanisms can be substituted for the ratchet-wheel and pawl.

As a means of displayin gadvertisemen ts, affordin g an additional source of revenue to the owners of one of my improved strength-testin g machines, I attach just back of the registering-dial I to a hollow shaft J a disk 1, upon which advertisements may be arranged upon or within the divisions or spaces i, (said divisions being indicatcd in Fig. 8,) two of which are displayed through openings of corresponding size formed in the dial I.

Within the frame B and upon the hollow shaft J are mounted a notched wheel N and a friction-wheel 0.

It is desirable that the shortest pull of the weakest operator upon the hook 0 may be sufficient to move the disk 1 far enough to display a pair of advertisements through the dialI; hence a train of spur-gears P P l I rigidly mounted upon their respective shafts, are employed for increasing the speed of the hollow shaft J, arranged as follows: The large gear I mounted on the shaft J, meshes with a small gear P, which is mounted close to a large gear 1 upon a counter-shaft J and the gear P meshes with a small gear I, which, with a f riction-wheel O, is mounted on shaft J. The latter imparts motion to the hollow shaft J by aid of the frictionwheel 0, and to insure perfect contact the wheel 0 may be formed of two parts 0 o, the part 0 having a hub which may be splined to the shaft J and upon said hub maybe placed the part 0. A spiral spring 0 surrounds the hub, and, bearing between the part 0 and a collar, also mounted upon said hub, forces said loose portion toward the stationary portion, and thus affords good frictional contact with the wheel 0.

The arms N N are mounted on opposite ends of a shaft N carried in bearings formed upon the frame 13, and attached to the free end of the arm N is a wire 01?, which extends thence to one end of a stop-arm N", the opposite end of which engages the notches of said notched wheel N. The said arm N" is pivoted to the frame B and held normally in contact with said wheel N by a spring '17.

\Vhen the hook c is being drawn out, a latch E, pivoted to the bar E and resting against the stop-pin c engages the upper end of the arm N, moving it forward until the said latch passes by, and as the said arms N N are rigidly fastened to their shaft in their respective positions this operation, by reason of the vertical wire 01 connecting the arm N with the stop-arm N lifts the arm N and leaves the notched wheel N free to rotate until the next notch presents itself to the stoparm, whereupon the advertising-disk I ceases to revolve, and the friction-wheels O O are caused to slip until the motion of the pullbar 0 shall cease.

As another means of advertising in connection with such a machine, checks Q, with the name and address of theadvertiser upon one or both sides, may be inserted in a tube R, having a slot in one side close to the bottom of sufficient thickness to allow a check Q to pass out, or a bottom B may cover onehalf of the tube, as shown in the dotted plan view projected from the sectional elevation, Fig. 11.

By slotting the bottom, as seen at R a push-bar B may force one and another of said checks down an inclined chute R and out onto a shelf A within easy reach of an operator. The rear end of said push-bar R is pivoted to an arm R and ad justably supported or automatically retained at the proper elevation by a spiral spring R one end of which is connected to said push-bar and the other to the arm R The upper end of said arm R is mounted upon a shaft S, supported in bearings formed on the frame A, and said shaft is rocked by means of its arm T, which comes in contact with the forward end of the frame E In Fig. 3 the arm 'm of the pawl M is shown to be formed integral with said pawl; but in Fig. 2 said arm is detached from the pawl and mounted upon the stud upon which said pawl is fulcrumed. Either form of construction is as good as the other, the former requiring the said arm m to be curved laterally in order to enter the slot h of the cointube II, while the latter construction permits the said arm to be formed straight vertically.

Having described the general-arrangement and construction of my improved machine, what I claim as new is- 1.
