To all whom it may concern."

Be it known that I, PEROIVAL EVERITT, a subject of the Queen of Great Britain, residing at London, England, have invented new and useful Improvements in'or Applicable to Apparatus for Indicating the Force of a Blow, (for which I have obtained patents in the fol.- lowing countries, namely: Great Britain, No. 8,404, dated June 25,1886; France, No.l8l,37 5, dated February 5, 1887 Belgium, No. 76,296, dated February 9, 1887; Italy, Vol. XXI, No. 21,370, Vol. XLlI, N o. 432, dated March 31, 1887, and Victoria, No. 5,134, dated June 17, 1887,) of which the following is a specification.

This invention relates to an apparatus which will indicate the force of a blow on a coin or tokenof predetermined value beinginserted in the apparatus. For this purpose I take any suitable apparatus adapted to indicate the force of a blow; but I so construct and arrange the indicating apparatus that it can only operate on the insertion of the required coin or token.

In order to enable my invention to be fully understood, I will describe the mode ofcarry- 7 ing the same into effect, which I find advantageous, by reference to the accompanying drawings, in which- Figure 1 represents a front elevation of an apparatus constructed and arranged so as to indicate the force of a blow on a coin or token being inserted in the apparatus, accordingto my invention. Fig. 2 represents part of asimilar view to Fig. l, but showing a portion of the front of the casing removed and part of the apparatus in section. Fig. 3 represents a side elevation, partly in section, of the apparatus; and Fig. 4, a horizontal section on the line 4 4 of Fig. 1. Fig. 5 is adiagrammatic view illustrating a slightly-modified form of the apparatus.

Similar letters in all the figures represent similar parts.

A represents the stand, and B the casing, of an apparatus adapted to indicate the force of a blow; B B, rear braces connecting the cas ing with the stand.

} O is the striking pad or cushion on one end of a tube, D, sliding in a fixed tube or guide,

E, and containing the spring F, the degree of compression of which determines the force of the blow, the said parts being of usual construction.

a represents the index or pointer of the ap paratus, which is arranged to move over a graduated scale, b.

c is a loose marking hand or pointer, which, by the index a bearing against a pin, a, thereon, is carried along and serves to mark or indicate the force of the blow after the index a has returned to zero, which it does immediately the blowhas been struck.

The index a and loose marking-hand c are respectively attached to rings d and 6, adapted to rotate upon a boss or short tube, f, forming a guide for the front end of the sliding tube D.

To the index a, Ijoin alink, g, which is at tached at its other end to one arm, h, of a twoarmed lever, h h, the fulcrum of which is shown at z. The free end of the arm h is bifurcated, as shown in Fig. 2, so that a pin or stud, j, on the end of an arm, k, fixed at Z to the sliding tube D, can pass through it when not prevented by a coin, Z, inserted in the apparatus, as and for the purpose hereinafter described.

at is a slit, through which the coins for successfully operating the apparatus must be passed, which slit is situated immediately above the space which normally exists between the bifurcated end of the lever-arm h and the pin or stud j, so that the coin will fall into the said space.

n a are pins fixed in the casing B, just below the end of the arm h, and on which the coin rests when first dropped into the machine.

ois aweight on a cord or thelike, 0, attached to the lever-arm 7a,. and working over a'pulley, p, for the purpose of bringing back the link lever h h, and index a to their normal posistud j. Theblow must then be struck upon the pad or cushion C, in the manner usual when using an ordinary machine for this purpose, and the pad G and the sliding tube D will thereby be forced inward to a certain extent, according to the force of the blow. This extent of movement will, by means of the fixed arm 7., in conjunction with the coin Z, becommunicated to the lever h h (which will be moved toward or into the position shown in dotted lines in Fig. 4) and to the link 9, and thereby to the index a, and loose markinghand 0. In thus moving, the lever-armh will describe an arc of a circle, and will therefore slide or carry the coin Z'away from the pin or studj, because this stud is fixed to the tube D, and the arm h changes its position relatively to this stud, and the coin, being then deprived of support, will drop within the easing, the pin or stud j then riding over the curved part or heel of the lever-arm h, as illustrated by the dotted lines in Fig. 4. The pad 0, tube D, and arm in will move back to their normal position immediately after the blow has been struck, and the lever h it, link g, and index a will be drawn back to their original position (shown by the full lines in Fig. 4) by the weighted cord 0. The loose marking-hand 0, however, will remain in the position into which it has been moved, and will thus serve to indicate the force of the blow which has been struck.

It will be understood that the loose marking hand 0 must'be' moved back to zero by hand each time the apparatus is operated, it being provided with a knob, 1', outside the front of the casing B to allow this to be done. Should a blow be struck upon the pad or cushion 0 of the apparatus without a coin or token having been previously inserted in the apparatus, the pin or stud j, as the fixed arm It moves inward, would pass between the bifurcation on the end of the lever-arm h, and would therefore not operate the indicating mechanism.

Instead of the arm It being fixed to the sliding tube D, as hereinbefore described and illustrated in the drawings, I sometimes attach it at any convenient point to a pivoted vertical lever or bar, e, arranged to be operated by the said sliding or movable tube D, as shown in the diagrammatic view at Fig. 5, the spring F being conveniently placed over a guide-rod, f. The other parts of the mechanism would be the same as those hereinbefore described.

Although I have described and illustrated my invention applied to an apparatus adapted to indicate the force of a blow delivered by a person's hand, it will be obvious that it is equally applicable to other forms of apparatus for indicating or' disclosing the force of a blowfor example, to such as may be employed for indicating or disclosing the force of zublow from a mallet or the like.

In some cases the cushion or pad that re: ceives the blow may be locked by a suitable retaining device, which is released by a coin being placed in the apparatus; but I find that arrangement not so advantageous as that hereinbefore described, as it is liable to injury or to cause injury to the striker when a blow is given while the apparatus is locked.

Handles may be applied to each side of the machine, whereby the operator, upon placing his bodyagaiustthe pad, may test his strength by pulling on said handles.

1 make no claim to anything shown or described in the application of R. V. Page, Scrial No. 216,665, filed October 19, 1886.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 'In an apparatus for indicating the force of a blow, the combination, with the frame and with the pad for receiving the blow and withits reacting spring, of a two-armed lever operated by such pad, a coin receiving and detaining device, a bar carried by the shank or shaft of the pad and operating as set forth, and connections, substantially as described, whereby the coin is caused to operate an index or indicator.

PEROIVAL EVERITT.
