F u e View oi another form of intermittent drive for the drum. 7

Referring first to the'construction shown in Figures 1 to 3 inclusive of the drawings, 2 designates a base on which is'secured a spring motor 3 of familiar type and on which are upright members 4 that supports a shaft 5 on which a winding drum 6 is secured.

Detachably set on the base 2 is an upright frame 7 havingvertical legs 8 and inclined legs 9. The vertical legs 8 have turned-in foot portions that engage under eye membrsr Q u ed o the bas 1 e inclined .egs 91 which a e nnec ed by lf- 5 ber h are se ur t v thsbe leb im o cleats 11 carried on the base 2 under which. he crossbar 9 s 1991 .6 1 ss e no in of the toy 8 is a somewhat diagrammatic Figure .1 2; I 16. we s fe e was 0t h reto is a erc si-p cesl a whi h for its principal object 7 and; which has aconsidj continuous pee .qfiel 'elr stifi' re-v.v Set 2 the we f; the t e lis a d Serial 1%. 116,118.

slidably vertically on the parallel vertical legs 8 is a block 14; having notched ends 15.

which straddle the respective legs 8 so as to slidably retain the block'on the legs. This block is supposed to imitatethe hammer of a pile-driver and is arranged to be raisedand lowered by means of a-cord 16 secured theretmthis'cord passing over the sheave 13 and having its end secured to the drum 6.

For operating the block 14, means is pro.- vided for intermittently driving and releasing the drum'6. In the construction shown in F igures l and 2 this means includes a mutilated gear wheel 17 driven by the spring motor 3. This mutilated gear is arranged to cooperate with a pinion 18 on the shaft 5 which carries the drum 6.

In the operation ofthe toy the spring motor 3, or any other suitable driving means which may-be'substitute'd therefore, contin uously revolves the mutilated gear 17. lVhen the toothed segments ofthis gear en'- gage the pinion 18-, the drum 6 isrotated several times to wind up the cord 16 and raise the weightor block 14L VVhen the toothed portion of the mutilated gear 1'7 passes/out of engagement with pinion 5, the

weight of the block 14 causes the bloclrto drop, unwinding the cord from the drum 6. Upon further rotation of the mutilatec gear 17 the drum 6 will again be rotated to lift the block 14: and in this manner the block 14 will be raised and dropped in simulation of the action ofa pile driver or similar piece of mechanism, and inasmuch as the action entirely automatic and mechanical, it affords considerable entertainment as a toy.

By having the stand 7'. detachably secured to the base 2, it can'be readily taken down and set in the broken line position indicated 7 in Figure 1, so that the toy can be convenientlyput in a box of relatively small size. At the'same' time the construction is so Sim that anyone can get up the stand upon set the toy in operanr I sk in e9 I the arrangement shown n Figures 4 to inclusive thefg'eneral arrangement is similar to that hereinbefore' described and s mi- Ia-i reference numerals have been used to designate the corresponding parts. I The forniof the inventionillustrated in Figures 4 to 7 inclusive eonta1nsa-d1fierent arrangement of gearing for intermittently trans- BY essi a mitting motion to the drum 6. In this form of the invention I have also illustrated an added feature which can be used equally well with the arrangement shown in Figures 1 to 3 inclusive.

Therefore instead of usinga mutilated gear, as shown in Figure 3, I have illustrated the motor 3 as driving a pinion 20 having a pair of pins or lugs 21- thereon at diametrically opposite points.

The pinionlS on the drum shaft 5 meshes with a continuous gear Wheel 22 carried on a shaft 23 in the support 4. The shaft 23 is slightly out of line with the center of the pinion 20, as best shown in Figures 6 and 7. As the gear wheel 20 revolves, one of the pins 21 will come into contact with a lug 24 on the face of the pinion 22, and rotate the pinion 22 through a limited arc until the difference in the alinement of the shafts shall cause the co-engaging pins or lugs to move out of engagement with each other. As soon as one of the pins 21, for instance, has moved past the pin 21%, the weight 14:

' will drop by gravity. By the time the weight .14; has reached the lowermost point of its movement the next pin 21 will pick up the lug or pin 24 of the pinion 22 and repeat the operation oflii'ting the weight and letting it drop. The particular advantage of this arrangement over that shown in Figure 3 is that the gears themselves will always remain in mesh, whereas in the construction shown in Figure 3 the gears are only intermittently in mesh, and if they do not happen to always fall into proper engagement with each other the toy will have a tendency to stick and the life of the gear 18 will be short. The arrangement shown in Figures 4 and 5 can be manufactured more cheaply and the toy assembled with greater facility due to the fact that less accuracy is required.

In order to add further to the action and attractiveness of the toy, a representation of a boiler with an operator standing adjacent it may be provided. In Figures 4 and 5, 25 is a'sheet of metal secured to'the base 2 adjacent the'motor 3 and which is shaped and decorated to represent a boiler. Pictured on one side of the plate 25 is a man and this picture of the man, designated 26 is provided with a movable arm 27 pivoted to the plate 25 at 28. The free end of this arm is pivotally connectedby a loose pivot to one end of a lever 29 pivotally supported on the boiler 25 at 30. The end of this lever projects into the path of travel of the pins 21. ,As the gear 20 revolves the pins 21 will rock the lever 29, giving a corresponding movement to the arm ofthe figure. This arrangement gives theappearance of an op:- eratorstanding beside a boiler operating a control lever, ,1 V H In the driving means illustrated in ure 8, the drum 32 is mounted in the supporting frame 33 on a shaft 34 which has a pinion 35 thereon corresponding to the pinion 18, shown in Figures 2 and 5. Meshing with this pinion is a gear wheel 36ihav-.' ing a pin 37 projecting out from the face thereof. The diameter of the pinion 36 is considerably greater than the diameter of the pinion 35 so that the pinion 35 will be revolved several times upon the partial revolution of the pinion 36. The pinion 36 is intermittently driven by successive engage- 37 on the gear 36 and thus rotate this gear through a limited are, after which the pin will move out of engagement withthe radial face of the gear, allowing the weight to drop, and allowing the gear 36 to rotatein the opposite direction by reason of the dropping of this weight. By the time the weight'has reached its lowermost position the next arm 39 will engage the pin 37 and repeat the operation. This arrangement also has the advantage that the gears are always in mesh. This arrangement has the advantage of requiring less accuracy in the setting of the parts than is required by either of the other two forms illustrated, so that it can be more easily assembled. The number of arms 39 may be varied according to the rapidity with which it is desired to raise and lower the member 14 and according to the distance which it is necessary to raise and lower this weight.

While I have illustrated certain preferred embodiments of my invention it will be understood that the invention may be otherwise embodied, and that various changes and modifications may be made in the construction thereof and the particular arrangement of parts within the contemplation of the spirit of my invention and under the scope of the appended claims. 1
