F0 @ZZ wie/om t muy concern,.-

Be it known that I, HERBERT S. MILLS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Coin-Controlled Punching-Bag Apparatus, of which the following is a specification.

The object of my invention is-to provide a novel construction of punching-bag apparatus which shall be dependent on the insertion of a coin of predetermined denomination to adapt it to register the force of a blow.

Referring to the accompanying drawings, Figure l is a perspective view of my improved apparatus, showing diagrammatically different positions of the bag by dotted representation; Fig. 2, a view of the apparatus in rear elevation with the back of the casing removed to display the mechanism within it; Fig. 3, a plan view of the top of the apparatus; Fig. 4, a broken view, partly in section, showing the coin-controlled mechanism on a` larger scale than that observed in the representation thereof in Fig. 2; Fig. 5, a section taken at the line 5 on Fig. 4 viewed in the direction of the arrow and enlarged; Fig. 6, 'a broken view of the register-actuating mechanism in elevation, showing the parts in the relative positions assumed by them as the result 'of inserting a coin into the appara-tus 5 Fig. 7 a broken view showing some of the parts represented in Fig. in the relative positions occupied by them in registering the force of a blow and to which they have been actuated by the eect of the blow on a pneumatic diaphragm; Fig. 8, a section taken at the line S on Fig. a and viewed in the directionof the arrow; Fig. 9, a broken view, in side elevation, of the coinchute mechanism actuated by the movement of the yielding platform under impact against it of the punching-bag, showing the parts in their normal relative positions; and'Fig. l0, a similar view of the same mechanism and additional parts controlling the .tripping of the registermechanism in the relative positions to which they are adapted to be brought by the action of an inserted coin.

A is the casing, expanded at its base for stability and having extended at a right angie from its upper end a frame A, supporting the overhead impact-board or platform A', which is hinged at one end to the frame,

as shown at a' in Fig. 3, to adapt it to yield at its opposite end, where it rests normally on the-top of theA casing. From the end of the frame A2 to which the platform is hinged depends the punching-bag B, on a rope o., passing loosely through a hole in the frame over pulleys a' and a2 on top of it, respectively, near Y its opposite ends and connected with coincontrolled mechanism, as hereinafter dewheel d, provided with a stop d to engage,

for limiting the return movement of the wheel, with an abutment d2' on a bearing fu, projecting backward'from the casing-front, a spiral springe having-a cord connection c with the shaft upon which it winds and tending to return the ratchet-wheel into the normal position, at which the stop d' engages the abutment. On a bearing e', Fig. 5, is pivoted a dog f, yieldingly held by a spiral spring f in engagement with the ratchet wheel and engaged by the shorter arm of a bell-crank g, fulcrumed at w and provided on its longer arm, near Vthe lower end thereof, with a cam projection g',`Fig. 9, which extends into the path of a coin E through the coin chute, as and for the purpose hereinafter described.

On the back of the casing-front, below the ratchet-wheel d', is supported a pneumatic diaphragm device F, comprising an upright cylinder h, having its upper end covered with a exible diaphragm h and open .at its lower end, through which a piston-rod h3 plays, car-V rying a piston h2, Fig. 4, and movable in a guide-bearing o2 and shown to be yieldingly held against rising by a spiral spring h4.

Above the diaphragm there extends loosely through the bearings e' and 'v' an upright bar i, having a disk-shaped foot fi', a notch 1'? in one edge above the foot, Figs. 6 and 7, and a lug e3 on its rear face above the notch in the path of a stud 4, projecting from one of the spokes of the ratchet-wheel. On an adjacent spoke of the ratchet-wheel is a stud 'i5 IOL) to engage, for apurpose hereinafter. described, with a dog 7c, pivoted on the bearing n to tend to enter the notch t2 under the control of a spiral spring 7c.

On the piston-rod h3 is fastened a crosshead Z', from the ends of which extend upright arms Z l', which are rigidly fastened at their upper ends to the free end of the platform A.

On a bearing 1:3, at the outer edge of the coin-chute C, is fulcrumed, at its lower end, a dog m, held yieldingly by a spiral spring m', to extend at its upper free end into engagement with a vertical bar n, reciprocably confined in bearings to extend along the outer open edge portion of the vertical part of the coin-chute and there close it. lVith the upper end of this bar is connected the bag-rope a, while the lower end of the bar is connected with the piston-rod 1f of an air-cushion G, of any suitable or known construction, and is also shown to be connected by a spiral spring s with the casing of the apparatus. In the outer edge of the bar n, near its upper and lower ends, respectively, are provided the notches n/ and n2, and between these notches there is provided in the face of the bar a recess n3, Fig. 9, converging toward the longitudinal center of the bar from its opposite edges. In the normal position of the bar n the recess n3 registers with the lower de [iected discharge end of the coin-chute C. On the face of the bar n is fastened, at its lower end, a trip-finger 0 to extend at its upper end into the path of a pivotal latch p, supported in position to adapt it to engage by gravity with a stud p/ on the bell-crank g near its lower end.

A pivotal cam q is supported to extend across the face of the bar n into engagement at its cam-face with a stud q on the dog m, and from near the free end of this cam it is connected by a rod 7' with the free end of a lever H, extending lengthwise along the top of the platform A', with its opposite end fulcrumed thereon and its free end confined in a loop/r against undue extent of rise.

The operation is as follows: In the normal relative positions of the parts the bar n is down and locked against being raised by drawing on the rope Ct to pull down the bag B into the position to be punched, (being the lowermost position in which it is represented in Fig. 1,) owing to the engagement of the dog m with the bar at the notch n', and the foot t" is raised above the diaphragm 7L', being held in. the raised position by engagement of the spring-dog 7c with the notch #in the bar t', Fig. 7. A coin inserted into the chute C in passing through it encounters the projection g on the bell-crank g, thereby turning its depending arm outward, with the effect of raising its shorter arm against the pawl f to disengage it from the ratchet-wheel, and thereby free the latter to permit it to be returned by the retractive force of the spring e against the shaft c2 until stopped by engagementof the stop d with the abutment d2, Fig. 2. In this position of the ratchet the index-finger c points to O on the dial. In the described return movement of the ratchet the stud encounters the pawl 7c to force it out of the notch i2 in the bar 'i to free the latter and permit it to drop, while the stud 4 encounters the lug 3 on the bar and insures the drop thereof, in the event'of its sticking, to the position in which it is represented in Fig. 2, wherein the foot t" bears on the diaphragm. It then remains to pull down the bag B. This is permitted by the action of the inserted coin, which passes from the discharge end of the coin-chute into the recess n3 in the bar n and attains the position of the dotted representation of the coin in Fig. 9, wherein it is confined between the downwardly-inclined base of the recess and the adjacent hollowedout edge portion of the dog m. rlhen by pulling downward on the pendent end of the rope ce the bar n is raised, and in rising the coin is rolled wedgingly out of the recess n3 between the straight edge of the bar and the dog m, thereby f orein g the latter outward and withdrawing it from the notch n to free the ba-r, which when it reaches the limit of its rise registers at its notch 17,2 with the engaging end of the dog to permit the latter to enter the notch under the force of its controllingspring and lock the bar in its raised position. Vhen the bar n reaches its raised position, the finger o encounters the catch p and lifts it off the stud 1J' to permit the bell-crank g to resume its normal position, wherein it is disengaged from the pawl f to allow the latters controlling springv to engage it with the ratchet-wheel. All is then in readiness for striking the bag. The blow impinges the bag against the under side of the platform A near its free end, and the impact raises it on its hinges with the following results: The rise of the platform, owing to its connection by the arms Z with the cross-head Z, suddenly shoots upward the piston h2, causing the air confined against the diaphragm to expand it, with the effect of jumping the foot t" and with it the bar t' upward. In the rise of the bar t' the stud i3 upon it encounters the lug if on the ratchet-wheel, and the impact turns the latter and with it the dial-finger c to register on the dial the force of the blow. Since the pawl f is in engagement with the ratchet, the latter cannot return toits normal position under the retractive force of the spring j" until the pawl is released by the insertion of another coin into the coin-chute, so that the registration of the last blow on the bag remains in evidence until then, and the bar c' is prevented from dropping by the dog k entering the recess 2 when it comes coincident therewith, thereby holding the foot t" out of contact with the diaphragm until by the' insertion of another coin the pawl f is tripped to permit the return of the ratchet to normal position, in assuming which the stud forces the dog 7c out of the recess and permits the bar and foot upon it to drop. Furthermore, in the rise of the platform it pulls upward on IOC IIO

the rod-fr, with the result that the cam q engages with the stud q' on the dogm and forces the iatter out of the notch 'a2 in the bar n,

which thereupon drops, under control of the air-cushion Gr, to its normal position, dragging with it the rope ce, and thus drawing up the bag B to take it out of the proper position for effective punching.

When vthe bar n is raised to its highest position, a recess n4 in its face, below the notch n2, is coincident with the coin, thereby so widening the space between the bar andthe dog m as to free the coin and permit .it to drop out into any suitable receptacle. (Not shown.) Tith the parts thus restored to their normai position the machine is ready to be again operated to registerlthe force of a blow against the bag after drawing it down to position.

The somewhat complicated nature of the mechanism has rendered necessary the foregoing minute description thereof in itsv details; but my invention is not intended to be limited to such details and I doV not wish to be understood as so limiting it thereto, since the construction may beV variously lmodiiied by those skilled in the art without departure from the invention.
