2 Claims.

This invention relates to toy elevators, and its general object is to provide ay motor operated elevator controlled by manually actuated means which when moved in one direction will cause the car to ascend and in an opposite direction, to descend, While in neutral position the control means acts as a brake for the motor, and renders the same inactive, thus power is not being consumed when the car is not running.

A further object is to provide a toy elevator including a housing for the car to travel in, and the housing has landings or platforms simulating oor levels, with doors at each landing, whereby access can be had to the car.

Another object is to provide a toy elevator with springs at the top and bottom of the housing to retard and cushion the car as it approaches the same.

A still further object is to provide a toy elevator, that is simple in construction, inexpen-f sive to manufacture,` and extremely eiiicient in operation, use and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings Wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a front View of the elevator which forms the subject matter of the present' invention.

Figure 2 is a sectional view taken approximately on line 2-2 of Figure l, looking in the direction of the arrows.

Figure 3 is a sectional View taken approximately on line 3-3 of Figure 2, looking in the direction of the arrows.

Figure 4 is a sectional View taken approximately on line 4 4 of Figure 2, looking in the direction of the arrows.

Figure 5 is a sectional view taken approximately on line 5-5 of Figure 2, looking in the direction of the arrows.

Figure 6 is a sectional view taken approximately on line 6-6 of Figure 4, looking in the direction of the arrows.

Figure 7 is a sectional view taken approximately on line 'I-l of Figure 4, looking in the direction of the arrows.

Figure 8 is a sectional View taken approximately on line 8-8 of Figure 6, looking in the direction of the arrows.

Referring to the drawings in detail, the reference numeral I indicates an elongated vertical housing which is preferably square in cross section in the form as shown, and may be of any appropriate height. The housing provides a shaft for the car totravel in and includes front, rear and side walls, and top and bottom walls, with partitions 2 and 3 within the housing adjacent to the top and bottom walls, as clearly shown in Figure 2 which likewise illustrates that the side walls have window openings therein.

The outer face of the front, rear and side walls are preferably painted to simulate bricks, as indicated in Figure l, and the front wall has platforms 4 secured thereto and extending horizontally therefrom, at equi-distantly spaced relation with respect to each other along the height of the housing, the platforms being supported by triangular bracing members 5, and extend from the front wall at the lower end of openings 6, each of which are closed by a pair of sliding doors l mounted in guide strips 8 secured along the upper and lower ends of the door openings, as clearly shown in Figure 2.

The doors of each pair are movable in unison with each other, and for that purpose I provide bell crank levers that include long arms 9 extending longitudinally of the doors and having their lower ends slotted, with the Shanks of knobs III mounted in the slots, for the arms to slide on the Shanks, and at the juncture of the long arms with the short arms II, the bell crank levers are pivoted as at I2 to the inner face of the front wall, while the short arms extend in converging relation from the long arms and have their inner portionsdisposed in overlapped relation and connected together by a pin and slot connection I3. By that construction, it will be obvious that when either one of the doors of a pair is opened or closed, the companion door will be moved accordingly.

Mounted for travel in the housing is a car I4 that is guided in its movement by channel members I5 fixed vertically to the side walls of the car and slidably mounted on strips I6 secured to the side walls of the housing, as best shown in Figure 3. The front of the car is open, and the side walls thereof are provided with window openings I1, while the top and bottom walls have lugs I8 struck and extending outwardly therefrom as shown in Figure 2. The rear wall of the car is preferably closed and it will be obvious that the car is arranged Within the housfrom the bottom wall of ing so that the open front will face the front wall of the housing, to allow access to the car when the doors 1 are open.

Connected to the lug of the top wall of the car isl one end of a cable that is trained about pulleys 2| mounted in brackets 22 and 23 secured to and depending from the top wall of the housing, the bracket 23 includinga coil spring so as to hold the cable taut at all times, as will be apparent. the cable extends along the rear wall ofthe housing and has its lower run trained about pulleys 24 and 25, and thence it is connected vto ly shown in Figure 2.

Fr'om the resiliently mountedr pulley 2|,

between a pair of upright bearingbrackets 26v secured to and rising fromV the bottom wall of the housing, and the pulley 25 is ixe'dto one en'd of a shaft 2l that has its ends journaled in iup-i right bearing brackets 28 secured to andrising the housing; 1sV Jbest shown in Figure 4. i

Ihe cable extends through openings in the partitions v2 V and Sand eachvv of the partitions have coil springs 29secured thereto in the `'path yof '4 the car to provide bumpers therefor, as' will be apparent upon inspectionv of Figure`2. i i

The power means for the yelevator in the form as shown,` is a spring motor which includes an open frame casing 3U provided with parallel portions having journaled therein` and bridging the same a pair 'ofA shafts 3| and 32, the shaft 3| having fixed thereto one end of a' coil spring33,

while its opposite end is fixed to a cross member y ,y

The means for transmitting the `power from the spring motor to the shaft 2 for raising and lowering the car, as well as for 'controlling the latter includes a shaft 39 having one end journaled in a portion of the casing 36 and its opposite end in an upright bearing bracket 40 securedl fixed to the shank 52 of a hand wheel 53, the shank being mounted for rotation in a bearing bracket 54 and in the side wall of the housing for disposal of the hand wheel exteriorly of the with the `tire 46, the wheel 45 will rotate in a direction to cause the car to ascend. When the 'hand wheel is moved in an opposite direction, the Y .left hand wheel 42 will be disposed out of contact with the tire 46, but the right hand Wheel 42 will'remain in engagement therewith for rotating the wheel 45 in a direction to cause the car to 'riesce/nd. HoweverLwhen both wheels 43 are engaged with the tire` 46, the car remains stationary vand vthe springsV 43 apply sucient pressureV against the wheels 42, for the tire 46 to act as a brake, to render the motor inactive, thus power is notbeing consumed when the car is not runlling.

I preferably provide a governor 56 mounted on the shaft 39, so that the latter will be rotated at the lsame speed at all times.

From the foregoing andthe disclosure in` the drawings, it will be obvious that the -car is under vhonstant control of theoperator at alltimes, to

be stopped and started as desired, merely by movement of the hand wheel 53 through themediurn of the knob 55, in eitherV direction, it depending of course uponwhether the operator desires the car to ascend or descend, with thefre- 4sult it'will be seen that my toy elevator will pro- 'vide' much amusement and fun AVand is manually controlled substantially inthe same manner as a real elevator.k v

Itis thought from the foregoingjdescription that the" advantages andnovel kfeatures of the 45` invention' will be readily apparent.

It is tobefunderstood that changes Vmay be `made in the constructi'orr'arrd inthe combination Vvand arrangement of the several parts, provided secured to the shaft 39 and meshes with the gear 38 so that the shaft 39 is rotated by the spring motor and the shaft 3S is square cornered for the major portion of its length,V as clearly shown in Figures 4 and '7. v Y i f5 Mounted on the square cornered portion of the shaft 39 to be carriedthereby, but for slidable movement thereon is a pair of disk'wheels`j42 normally urged toward eachother by coil-springs 43y qU'v D vwhat 1 claim is;

changes fall within the scope ofthe pp'endedjclaims,
