3 Claims.

This invention appertains to toys, and more particularlyto a'novel toy trip hammer.

One of the primary objects of my invention lis to provide novel means for raising the hammer onV each stroke of an operating lever, whereby the sion of resilient means located in the path of theA head, so th'atas the hammer and the head are raised, the spring member will be flexed, and thus give an initial downward impulse to the hammer as the head rides 0H of the rocking arms.

Another important object of my invention is to provide a toy trip hammer, which will present a pleasing and attractive appearance, and closely simulate the action of a large trip hammer, and thereby give a maximum amount of pleasure to a child.

A still further object of my invention is to provide a toy trip hammer, which will be durable and efcient in use, one that will be simple and easy to manufacture, and one which can be placed upon the market at a small cost.

With these and other objects in view, the invention consists in the novel construction, arrangement, and formation of parts, as will be hereinafter more speci'iically described, claimed, and illustrated in the accompanying drawing, in which drawing:

Figure 1 is a front elevation of the toy, with one of the cover plates removed, parts of the frame being shown broken away and in section to illustrate the means for anchoring the return spring in place.

Figure 2 is a fragmentary side elevation of the toy, illustrating means of operatively connecting the rocking arms to the operating lever.

Figure 3 is a detailed vertical section, taken on the line 3 3 of Figure 1, looking in the direction of the arrows.

Referring to the drawing in detail, wherein similar reference characters designate corre- "sponding parts throughout the several views, the

letter H generally indicates my improved toy trip hammer, which comprises a supporting base plate 5 having rigidly connected thereto the upstanding side standards 6 and Y'1. The lower ends of the standards 5 and 'l are slightly arched, as at 8, and receive therebetween the stationary anvil 9, which is rigidly secured to the upper face of the base plate 5. Above the anvil 9 the standards 6 and 'l are formed to provide a vertical guide i i! for the hammer I I. The hammer l I is mounted for reciprocatory movement in the guide I0, and the hammer can be provided with guide straps i2 for engaging the opposite faces of the standards and 1.

'Ihe hammer has rigidly secured thereto the upstanding operating rod I3, which slidably extends through a guide plate standards. The extreme upper end of the rod I4 has formed thereon, or secured thereto, an inverted V-shaped lift head I5, having oppositely inclined side edges I6 and abrupt bottom shoulders Il.

In order to bring about the quick and eflicient raising and lowering of the hammer Il, I provide lock arms i8 and I9, which are disposed on opposite sides of the rod I3 and its head I5. The arms i8 and I9 are in the nature of bell cranks, and are pivoted at their angles on a transversely extending shaft 20 carried by the standard 1. This standard l is slotted, as at 2|, to receive the arms, and the arms are formed relatively thin and of a resilient nature so that the same will flex, for a purpose which will be later set forth.

The extreme outer ends of the arms I8 and I9 have pivotally connected thereto depending links 22 and 23, the lower ends of which are pivotally connected, as at 24, to an operating lever 25 on the opposite sides of its pivot 26. The pivot 26 is anchored to the standard i adjacent to the lower end thereof, and the outer end of the lever 25 is extended (not shown) to form an operating handle. Referring again to the rock arms I8 and I9, it is to be noted that the inner ends thereof have formed thereon arcuate extensions 21, which are adapted to engage under and ride from beneath the head I5 of the rod I3.

In operation of my improved toy, the operating lever 25 is raised and lowered by the child, and the hammer will be raised both on the up stroke and down stroke of the lever. As the lever 25 is actuated, the arms I8 and I9 will be alternately raised and lowered. As one of the arms I8 or I9 is lowered, its bottom edge will ride on an inclined side I6 of the head I5, and the arm will be iiexed and ride past the head. When the hammer reaches its extreme height, the arm which is elevating the hammer will ride from I4 carried by the l5 2 under the head I5, and allow the hammer to drop against the anvil under its own weight. As the hammer falls, and the lever 25 is again aotu ated, the armfwhich was brought to a lowered position, will engage one of the abrupt shoulders l1, andY lift up the head l5, the rod I3, and the hammer Il, and as the head raises the other arm will spring past the head and move to lowered position. Thus, as the arm, which is raising,V rides from under the head, the hammer will fall, and the lowered arm will be in position for again raising Vthe hammer. Y 'i If soV desireds I can YprovideY a leaf :spring 3B arranged in the path of theghead l5, so that when the head is raised the spring 3) will be exed, whereby When an armrides from under the head the spring will exert? an initial impulse Y for moving theY hammer down.'

Asshown, the ends of the spring Se are secured to the standards 6 andr'l, and arerheld in place by a top ywall 3l. Front and rear plates 32 and 33 can be secured to the standards 5 and 1 So as to form a closure for the operating parts of the hammer. ff 'i Changes ini details Ymay` be made without departing from the spirit or scope of my invention, but what I claim as Ynewis:

1. A toy comprising a frame, a hammer reciprocatively mounted in said frame having a sub stantially V-shaped head provided with inclined sidesand abrupt bottom shoulders, a pair of reak armmounted on the frame disposed on opposite sidesfof the head and adapted to spring past said headfand under said shoulders, means for alternateiyV operating said arms, and a spring disposed in the path oisaid head foi; giving-ian initial impulse thereto. e

s 2. LA toy comprising a frame, a hammer slidablyfmounted in said frame, an anvil*V carried by the frame disposed below the hammer, an eperating rod secured to the hammer, an invented V-shaped head on said rod havingY oppositely inclined sidesVY and abrupt bottom shoulders, rock arms of a bell crank shape rockablymounted at theirangles on the frame, the inner ends of the rookrarms being'pr'ovided with flexible arcuate extensions adapted to flex past said head and under the shoulders upon downward movement thereof, said arms being adapted to ride from under the shoulders upon upward movement of the arms and hammer when the arms and hammer reach a predetermined position; an operating lever rockably mounted: on theframe, and links operatively connecting the outer ends of the rock arms with the lever on opposite sides of its pivot. i

l3. A toy comprising a frame, a hammer slidably mounted in said frame, an anvil carried by the frame disposed below the hammer, an operf atingY rod secured to the hammer, an inverted V-shaped head on said rod having oppositely inclined sides and abrupt bottom shoulders, rook arms of a hell crank shaft roekably mounted at their angles'on the frame, the inner ends of the rociz arms being provided with flexible 'areuate extensions adapted toflex past saidjhead and Y under the shoulders upon downward movement v thereof, said arms being adapted to ride rom under the shoulders upon upward movement of 3= the arms and Yhammer when the arfrns and hammer reachaaJ predetermined positiGl, an operatey ing lever roekably mounted on theY frame, links operatively connecting the outer ends of the rock arms with the lever on opposite sides of its pivot,

anda leai spring disposed in the path of the head and adapted to be;Y flexed Yby saidrhead when the head reaches its estreme raised position.
