To all whom tt may concern:
citizen of the United States, and resident of Brookline, inA the county of Norfolk and State of Massachusetts, have invented new This nvcntion'relatcs to exhib iting appasection, of'an apparatus for exhibiting the The working parts of t-he apparatus are frame A. Mounted on the casing A is a' oot form B, which hol ls the stocking to lbe tested. T-lie form B may be rigidly and immovably mounted on the casing, but is preferably movably mounted,'as by the pivot b, and is held to very slight movement by a pair of opposed springs s, which yield slightly in thus ease or cushion the blow to some extent.
At either side of the foot form B are hamoppositely arranged, dummy hands and arms E, E', which are pivoted to the case A thc relative proportions and arrangements of the parts are such that the hammers when swung on their pivots, travel in paths to strike the toe and heel respectively the Patented Nov. 1, 1910.

foot form permissive blows, the paths or directions of the striking blows of thetwo hammers being substantially opposed to each other. I The operat-ingmechanism illustratedin Fig. l consists of the reciprocating bar l" mounted to slide lengthwise in= ide- 4ways provided inthe supports f, wlicgilz1 are secured within tliecasing A. Aniotor M, preferably an electric motor, is mounted' on the base of the casing, and drives a pulley P by means ofa belt p. The pulley-P is, journaled on bracket p', and is provided with a pitinan yf-which actnates the rciprocatin bar F ,tl1rou`gh the arin p. Latches C an 'C are mounted in the casing on pivots c `and c, each latch adapted to engage a notch c2 or c, providedlin a disk or plate e* secured to cach. arm about the pivot. Latch operating pins f2 are secured to the bar F, and the bar "F is connected at its ends with the lower ends of the arms 'E and E by exible straps and f4, as shown. In the position shown in the drawings the bar F is shifted to its ing niec'anisin by which the bar F is connected with the motor, causes the bar to start from the position shown in the drawin toward the left, the arm E andhaininer will be lifted away from the foot form B,
strap f*. At the same time the pin f2 Wifi move away from the lower lever arm of latch C leaving the same free to drop into notch c when the notch comes opposite the end of the latch. As the bar F approaches its left hand position, the arm E will be swun upward until latch C drops into note e, holding the arm E' and hammer D' in elevated position, and the lefthand pin fz'will engage and swing the lower lever arm of latch (l, thus throwing the latch out of engagenient with notch c2 and permitting the arm E and hammer D to fall and strike the toe of the foot form. It will be understood that the strap f slackens during -the left hand movement of' the bar F, since the n in E is held upright until the pin f2 Atrips the latch C, and hat the fall of the arm and hammer takes up the slack. The reverse movement of the reciprocating bar F opelates as already described, first lifting arm E and .hammer D, andthen releasino` ar E and hammer D and resetting arm anti hammer D again in the position shown in caused alternately to strike the foot form.
It will be seen that the arms E and E' carrying-the hammers are pivoted at points sutliciently far removed from the foot. form 'foot form a ,pereussive blow.
so that their strikino`r blows may be effected by gravity, since theii` centers of gravity never. pass outside of their pivotal centers.
when'the arms are raised to their highest points. Furthermore, when the mechanism shown in Fig. 1 is used, each hammer is lifted out of engagementwiththe foot form when the other hammer strikes its blow.
Referring' now to the form of operating mechanism shown in Fig. the reciprocating bar F andthe means for actuating the same may be as already described; and the disks or plates c* having the notches e2 and es, serviiigas levers for lifting the arms and hammers, may also be substantially the same asl already described, save that the notches are located at the bottoinsinstead of the sides of the disks. Pivoted to each end of bar F is a yielding latch g, normally held projected as showh, by spring g', a stop g2.
limitin the extent of the upward movement of the il 2, the' bar F is at itsextreine right hand-position. As the bar F inoves toward the left, the right hand latch f engages notch e3 and lifts arm E and bzi'mmeLD away from the foot form B, and the left hand latch g yields until -it passes clear of the edge of notch e2 and snaps into* said notch. J ust before bar vF reaches its extreme left hand position, notch e3 which has been swung upward by the movcmeiitof the bar, slips ott' the right hand latch g, aiid releases the arm E and hammer D', which fall by gravity, and the hammer D strikes the heel of the A similar action takes place with respect to the arm -and haminerll and D when the bar F moves toward the right, and' the'ha'mmers l) and D are caused alternately to strike percussive blows upon the Vtoe and heel of the foot form, andA consequently upon the' stocking held thereby, as the bar reciprocates, atliording a cons )icuous demonstration of the durability'of t e article subjected to such repeated percussion.
n-the form shown in Fig. 2 eaehhaininer rests against the foot form when theother hammer strikes its blow, whereas inthe form shownin Fig.1`each hammer is retch. `In the position shown in vFig.

2. ln an exhibiting apparatus, a foot form pivotally mounted and held to slight yielding movement by opposed cushion springs, a hammer at each side of said foot form, one hammerpivoted to' swing in a path to strike the toe .of said form,.and the other hammer pivoted to swing in a path t0 strike theiieel of said form, the striking blowsl of -said hammers being directionallyv opposed to eachother, and means to reciprocate said hammers alternately so as to strike hammers.
4. In an exhibiting apparatus, a form adapted to hold an article of wearing apparel, a hammer at each side of said form pivotcd to swing in a path to strike said form, by gravity, means to swing said ham-l mers through their return. strokes and -to release them at the'ends thereof, and means.
whereby each hammer will be removed from contact with the form when the other hamnier strikes the form'.
