Application October .25; 1948, Serial No. 56,422

,The, invention relates to an automaton or manikin, namely a self-moving machine which imitates life like motions.

An object of the invention is to provide an automaton having a movable head, with means for turning the head from one side to theother andfor tilting the same in alife like manner.

Another object of the present inventionis to provide an automaton having a movable head and movable arms which are operated in timed relation with each other in a life like manner, particularly to simulate the act of cobbling a, shoe. -Our invention relates to advertising mediums anclhas for its object to provide a new and highly efficient meansfor and method of attracting attention of traffic passing down a busy street to the fact that cobbling or shoe rebuilding is being done.

:A further object is to provide an automaton which simulates the act of nailing a work piece. A further object is to-provide a puppet shoe maker working on a shoe with all appearances of driving a nail into the heel of the shoe.

The invention provides a miniature man giving all the movements of hands and arms and head of a shoemaker driving nails into a shoe, the hammer driving'the nail, the hand traveling to the mouthv as though gettinganother nail and then down to the heel ofthe shoe where, when the hand again leaves the shoe a-nail is visible stick- 6 Claims. i(Cl. 40-126) Figure 6 is a plan view of the cam for operating the hammer-operating arm. 1

Figure 10 is a plan view of Figure 9.

Figure 11 is a view of the base of the neck,

which rests on the ramp shown in Figure 9.

In the drawings we have shown our mechanism as a model of a man A, seated on a cobblers bench B, to which the cobblers tray C is attached by mounting the entire'device .Ollifi/ base 5. One

arm 2 of the body is provided with a hammer .4

simulate the work of a cobbler. $1 is. raised to the mouth as though taking a tack and the other arm 3 is provided with the hand iv showing the fingers as though they were grasping a shoe nail. The hands are operated to The left hand ,4

the hand 4 is raised from the heel of the shoe ing up from the heel of the shoe and which, nail is then struck by the hammer and driven down into the shoe. p I Theclaims in this case are being limited to the nailing feature, while claims generic to this case and to co-pending application Serial No. 101,522 g filed June 27,1949, for AUTOMATON are being-v made in the latter case, particularlywith regard to the head cam, the cam assembly and to cams pears and giving the positions, of the hands at two different positions of the operation.

Figure 2 is a rear elevation of Figure 1, parts cut away to show the operating parts of thedevice. I I

Figure 3 is a section on line 3-3of Figure 2;

; Figure 4 is a perspective diagrammatic illustration of the various cams, shafts, and operating parts of the invention.

Figures is a plan viewof theeam for operating the left arm.

a-nail N is shown ready to be .driven by the hammer. This nail N is the top end of a rod which extends down through the heel and is raised and held by friction until the hammer strikes it, being raised to the elevated position while the fingers of the hand 4 are in contact with the heel, as shown in Figure 1. The head A is slightly raised and lowered while it is being partially rotated from side to side in such a manner that it gives all the appearances of a natural person working on a cobblers bench repairing shoes. Each time the hammer drives down it forces the nail down into the shoe heel and each time the right hand is raised and the left hand lowered to simulate withthe device.

placing a nail the nail N is elevated to. the raised position so that when the hand leaves the shoe heel it gives all the appearances of having left a nail sticking in the heel ready for the hammer.

The operating mechanism for the device consists of a casing D in which the worm gear for driving the device is mounted and in which the operating cams and races are all mounted and operated, the casing being adapted to be completely enclosed and filled with oil to prevent wear on the cams and their coasting rollers and arms. Transversely through the case D there is a shaft S which carries all of the cam races and the driving worm wheel W. The worm wheel W is driven by a worm driven directly by the motor M,

the shaft M extending down from the motor to the worm inside the gear boxing. The motor M is mounted on a bracket extension on the back side of the casing D and the motor is mounted on an angle and provided with a cooling fan F to direct air currents over the motor to keep it from overheating from constant running.

On the shaft S there is a cam 12, the perimeter 13 of which is formed to actuate the left arm in its desired motions by the connecting or contacting roller l4, shaft [5 and pivot block Hi. The

pivot block I6 is provided to enable the builder to get the shaft perfectly placed by use of the set screw I! in the block IS. The end of theshaft i5 is pivotally attached to the vertical rod 18 man. An extended arm 21 connects the shaft 20 with the arm 3 and supports and operates the arm. A counter weight .22 is attached to the shaft 29 to aid in raising the arm.

The nail N is mounted through the heel of the shoe l0 and is the upturned end of a rod 24 which operates in the slot 23 of the last support 9 which supports the shoemakers shoe I0. The rod 24 extends through the slot 25 in the seat B and is attached to the rod 25 which is pivoted through the back of the case D with the other end bent forward at 28 carrying a roller 30 operating on the cam 29, which cam is also mounted on the shaft S.

A cam 31 is mounted between the cams l2 and 29 and actuates the right arm by a roller 33 operating over the two ramp or cam surfaces a and b. The longersurface a is to simulate the full hammer stroke, while the shortersurface b is to Having thus described oiii invention; we claim:

1'. An automaton comprising a replica of a shoe maker seated on a stool; a shoe placed between his knees; a movable right arm holding a hammer, a movable left arm holding the fingers in a position simulating holding a nail; said shoe slidably holding said nail in the path of said hammer and in the path of said fingers of the left arm, a movable neck and head simulating looking down and then around; and a multiplicity of cams, and connecting arms to cause the movable parts of the body to be actuated by the rotation of the cams, one-of said cams and connecting arms being operative to raise said nail to a position projecting above said shoe, and another of said cams and connecting arms being operative to lower said hammer into driving relation with said nail.

2. An automaton comprising a body having a movable arm carrying a hammer, a work piece for simulated nailing, a rod projecting upwardly through said work piece and slidable to one position with a free end of the rod in the path simulate the short stroke of the hammer when 7 just setting the nail. This stroke is when the hand A is resting on theheel and appears or.

simulates the setting of the nail after which the hand is removed and the hammer strikes the nail N, driving it down into the heel hole. The roller 33 is on the end of a rod-3Q which is pivotally mounted in the block 85 by the set screw 36. The end of the rod 34 is attached to the shaft 31' which extends up into the body of the man and the top end of the shaft 31 is attached tothe 'lever 38 which is mounted on the transverse shaft 39 mounted across the body of the man. The end of the shaft 39 is bent forward and the arm 2 is formed thereon. a

The head A is operatedby a cam race plate 43 carrying a cam groove or race 4| in one face thereof in which cam 42 is operated. This cam 42 is mounted on the rod 43 which is passed through the rear face of the case D using the case as a bearing therefor and the other end is turned down at the'rod M which rod is attached'to a b10ck'45. 46 which is mounted through an arm 4'! on a vertical shaft 48. The top end of the shaft 48 -is carried in an operating sleeve 50 and the top end of the sleeve 50 is formed as a universal 5| to allow for the nodding motion imparted to the each of said cam means comprising a radial type of said hammer and projecting above said work piece and simulating a nail, said rod being slidable to a lower position with said free end within said work piece, cam means for raising said rod to said first position, and other cam means for operating said arm.

3. An automaton according to claim 2, said work piece having an aperture therethrough for frictionally holding said rod in said first position,

said other cam means being adapted to drop said arm with its hammer and. cause said hammer to drive said free end of said rod to its said lower position.

4. An automaton according to claim 2, a shaft,

cam having a dwell and mounted on said shaft.

5. An automaton for simulating nailing a work piece, said automaton comprising a rod projecting upwardly through said Work piece and mov-' Z able to one position with a free end of the rod projecting thereabove and simulating a nail, said rod being movable to anotherposition within said work piece, a body having an arm having fingers movable into and out of the path of said free end,

" said body having another arm carrying a hammer movable to strike said free end, and a separate cam means for each of said arms and for said rodrsaid cam means being operable in timed relation with each other to simulate nailing said work piece.
