SPECIFICATION forming part of Letters Patent No. 258,218, dated May 23, 1.882.

Application ined February 20,1882. (No model.)

To all 'whom it may concern: t

Be it known that I, JOHN GAssiDY, of the city of Cambridge, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Clogs," of which the'following is a full, clear, and exact description, reference being had to the accompanying drawings, in which like letters indicate corresponding parts.

Figure 1 is a vertical section of the clog, in which is represented the pyrotechnic device, consisting of the principal parts B and C. Fig. 2 is a section of the heel of the clog. Fig. is a vertical section ot' the front side of the heel ot the clog. p Fig. 4C is a section ot' the device C B z y, end view. Fig. 5 is a section representing a 'side view of the same parts enlarged from Fig.l.

rEhe object of my invention is to make a clog with a self-adjusting device for discharging percussion-caps, torpedoes, or similar explosives while in use, at the will of the wearer v of the clog.

It is evident that the discharge of torpedoes, percussion-caps, or similar explosives by some simple device under the control of the wearer, and which can be operated without interference with the ordinary use of the clog, must materially add to the display' and pleasurable sensation evoked by the dancer. Therefore, to effect this most desirable result, I form the clog of the upper A, the lining d, and the In order to make the clog light, I place between the sole b and the upper-liningd apiece ol' cork or similar material, (represented by c.) This also gives elasticity to the sole and ease to the wearer in use. Through the sole b, I pass the rod B, having a small knob or button upon its end, x',

attached to the rod B by a swivel-joint. Theopposite end of the rod B is bent vas shown iu w. Just forward ofthe heel I support a circular sleeve, C, by the connection x2. The sleeve Gis formed with teeth or inclines or bevels upon either end, as represented by y. The part() is stationary, being supported by the connection x2 with the sole of the shoe b. The rod B revolves inside of the stationary cylinder G. Upon the rod B, I place the studs z z, one upon each side of the cylinder C. rlvhe caps or other explosives are represented by e e,

and are placed upon the heel oi the clog, as

shown in Figs. 2 and 3.

The discharging device is operated as follows: The wearer strikes or presses the rod B upon the knob which presses the rod longitudinally toward the heel. The stud z, engaging with one of the teeth y, follows the incline of the tooth, and thus turning the rod B the distan ce represented by the incline of the tooth. The rod B is then sprung back to its place by means of the spring y. AIn returning to its position the teethv upon the opposite side ofthe cylinder U, toward the heel, are so formed that the stud upon that side, z, engages one of the teeth ofthe cylinder, and, following the incline as the rod B is drawn back, continues the turning ofthe rod B, as already explained, in pressiugit in by striking upon x. The rod Bis now in position to be struck again upon the knob m', and the teeth opposite to the forward stud, z.,

are in a proper position to act upon thestud.

and partially turn the rod, as already described. Thus by striking or pressing upon the knob .r the rod B is revolved, andthe bent end of the rod w is projected against the parts e e, following in succession the circle ot' explosives, as represented in Fig. 3.

The operation 4of pressing upon the rod B is to turn the rod and to explode the percussion-caps, placed as represented in Fig. 3. Of course it is obvious that this sauie principle and substantially the same mechanical device may be used for the same purpose in some other form-or placed upon some other part of the clog. For instance, my device may be placed so as to be struck from the heel instead of from the toe ofthe clog, or from the side. The position where the device is operated is im material. I preferably make an orifice through `the heel, as represented by dotted line from e to 7c, Fig.2. By this means the tire or dash of the eX- plosives is seen at lo. Thisis a very attractive addition to the eect produced by my pyrotechnics and discharging mechanism, as heretofore described.

Having now-described my invention, what I claim, and desire to secure by Letters Patent ot' the United States, is-

1. A clog having a holding device in the breast of the heel for explosives, and a discharging dcvice attached to the vsole, and

adapted/to operate substantially asand for the purposesspecie'd.

2. In a clog, the rod B, knob x', spring Q', and the studs z z, in combination with the cylinder C, having teeth or inclines upon each side, yy, substantially as and for the purposes set forth.

3. A clog provided with explosives arranged in a circular position upon the heel, in combination with a discharging mechanism attached to the sole of the clog, all adapted to be operated substantially as and for the purposes set forth.

4. The combination of the clog A, having a sole, b, and heel a, with the pyrotechnic discharging device B, with button m', spring 'i f,
