8 Claims. (01. 155-59) This invention relates to toy swings, and more particularly to those in which a spring motor is used for imparting motion to the moving element of the swing.

One of the objects of the invention is to provide an attractive toy in which movement will be imparted to the swinging member for a considerable length of time before it is necessary to rewind the spring motor.

Another object is to provide an improved arrangement of elements in a device of this kind with a view to providing a device which is durable and will not easily get out of order and will give satisfactory service to the user.

In the accompanying drawings:

Fig. 1 is a side view of a device embodying the invention, the frame being broken away to omit the side frame toward the observer;

Fig. 2 is a top plan view of the toy swing;

Fig. 3 is a section on line 3-3 of Fig. 1;

Fig. 4 is a section on line 4-4 of Fig. 2;

Fig. 5 is a section on line 5-5 of Fig. 4;

Fig. 6 is a detail section taken on a line indicated by arrow 6 on Fig. 5;

Figs. '7 and 8 are, respectively, sections on lines 1 -1 and 88 of Fig. 4; and

Fig. 9 is a section on line 99 of Fig. 4.

In the form shown in the drawings, the device comprises a swing having a stationary frame or standard, including side frames adapted to rest on the ground or on a floor, and a swinging element comprising pairs of swinging bars or arms interconnected at their lower ends by a floor or foot rest, each pair of bars carrying a seat. The pairs of bars are adapted to swing on axes provided by crossbars interconnecting the top portions of the side frames. Supported on top of the crossbars is the base portion of a spring motor, said motor including a spring casing disposed at the upper part of the swing where it is readily accessible for winding. The spring motor has an escapement elementof novel form, and this element is connected by novel means with the swinging element of the swing in the manner hereinafter more particularly described, so that, when the oscillation of the swinging member is started, it will be continued for some time, that is to say, until the coil spring in the motor is substantially unwound or deenergized.

In this form, the escapement element of the spring motorv acts upon a lever pivoted intermediate of its ends to swing in a substantially horizontal plane, one end of said lever being connected to the escapement element to be actuated thereby, and the other end of the lever being connected to a reciprocating bar interconnecting the two pairs of seat-supporting bars.

In the drawings, the stationary frame It] of the swing comprises the side frames Ill and Ill interconnected at their upper ends by the crossrods ll, l2. These crossrods act as supports for the swinging element l3 of the swing. This element comprises a pair of bars l4 and a pair of bars l5, said bars being interconnected in the usual manner by a foot rest IS. The pairs of bars also have associated therewith seats I! and I8. All of the parts mentioned to this point are preferably made of metal, and the swing shown is one constructed of metal.

The spring motor is generally indicated at l9, 5

Referring now to the details of the motor and escapement mechanism, it will be noted that the base 20 of the motor includes a top plate 26. The ends of the plate 26 are spaced upwardly from the crossrods II and I2 by spacer members 21, and in this form screws 28 extending through the end portions of the plate and through the spacer members attach the plate to the crossrods. A plate 29 is parallel to the plate 26 and provides an enclosed space beneath plate 26 in which the escapement wheel 24 is received. The lower end of the arbor 23 extends into a hole in plate 29. The end portions of the plate 29 are spaced from plate 26 by spacers 3|, and screws 32 pass through the plate 29 and through the spacers so as to secure the lower plate to the upper plate.

The escapement wheel 24 is riveted to a hub 33, and this hub is fixed to the arbor 23 by means such as a crosspin 34. The escapement wheel has a plurality of teeth 35 with inclined side surfaces, the arrangement being such that between any two adjacent teeth is a V-shaped' space 36, the side boundaries of which create and define between them an angle of These interdental spaces of the escapement wheel are adapted't'o be engaged by the pallets or pawls 31, 38 of the sliding escapement bar 25.

Referring to Figs. 2 and 3, it will be noted that one of the bars I5 is provided with an extension 39 which projects upwardly above the adjacent crossbar so as to provide a swinging bar oscillating about an axis somewhat below its upper extremity, and it will be noted that bar I 4 at the same side of the swing is provided with a similar upward extension 40'. These extensions 39 and 40 are interconnected at their upper parts by an element adapted to move longitudinally of the swing and constituted in this case by a bar 4|. This bar receives motion from the spring motor in the manner to be described later on, and when reciprocated causes oscillation of the movable swing element. In the form shown the bar 4| is pivoted at one end to the extension 39 by means such as a screw 42, and at the opposite end it is formed with a slot 43 engaging a pin 44 carried by the other extension, so that that end of the bar is supported for the generally reciprocating movement of the bar which takes place in the opera tion of the device.

The connecting bar carries intermediate of its ends a fixed downwardly extending pin 45, and this pin is engaged in a notch 45 in one end of a lever 41 that is actuated from the spring motor to oscillate in a horizontal plane. The lever 41 is fixed with relation to the spring motor by be ing pivoted intermediate of its ends on the bottom plate 29 of the .motor base. The lever 45 is spaced downwardly somewhat from the plate .29, .and is pivoted to said plate by means such as a screw 48 screwed into a socket in the plate 2.9, the lever 41 being spaced from the plate 29 by an intervening sleeve 45, as shown in Fig. '19. At the end opposite the slot 455, the lever 4! has a second slot 55, and this slot 50 is engaged by the body of a member such as a screw 51 disposed beneath the escapement bar 25 and having a threaded shank engaged with a threaded .socket in the escapement :bar, as shown in Fig. 9. The

pivot orfulcrum 48 of the lever 47 is located much nearer the screw than it is with reference to the pin 45, the consequence being that that arm of the swing-operating lever which is moved from the spring motor, as hereinafter described, has considerably less movement than the arm of the lever which :actuates the connecting bar.

It-will be observed that in the form shown the sliding escapement bar .25with its pallets or pawls is made up of separate pieces suitably interconnected, although this is not necessary in all cases. In the form shown, the pallets '37 and 3B are formed as separate blocks having opposing V- shaped faces adapted to fit the spaces between the teeth of the escapement wheel, said blocks having lower surfaces adapted to slide against the upper surface of plate 29, and upper surfaces adapted to slideagainst the lower surface of plate 26. The plate 22: is provided adjacent the respective ends with slots 52 and 53, which are overlain by the respective pallets, the pallets being connected to the escapement bar by screws 54 and 55, respectively, which screws pass through guide f portions 56 and 51, respectively,ithat are formed on the pal-lets and located in the slots 52 and 53. The guide portions fit the respective slots, and it will be :noted that by this arrangement the member 25 is guided rectilinearly in a precise manner .so that the pallets will engage the escapement wheel properly.

The escapement wheel is spaced downwardly somewhat from the plate '26 by means of a spacer 58.

The spring case 2!, previously mentioned, has a main portion formed as an inverted cup, and. it has a separate bottom member .59 which rests on the plate 26. This bottom member is provided with a series of apertures 50, and these 1 '1 finger 61 may .be fastened to the plate 26 by rivets, as shown in Fig. -6. It is understood, 10f

course, that the bottom member 59 is suitably fixed to the body of the spring case. The spring case .has a side wall which is preferably knurled exteriorly, as shown in the drawings, sothflt. the

.case against unwinding movement. The spring I 4 case can be grasped by the fingers for turning it, and thereby winding up the spring, and as the case is turned the case bottom 59 moves with it and the engagement of the spring finger with the apertures or recesses in the case bottom prevents retrograde movement. At its outer end the spiral spring is made fast to the case as by employing afastening member 63 engaged with the side wall of the case, as shown in Fig. 4. The inner end of the spring is fastened to the arbor 23 by the use of a iastening member 64 or other fastening means. At the top of the arbor 23 is a cap member 23 overlying the upper wall of the case and preventing dislocation :of the case in an upward direction. The .arbor is restrained from upward dislocation by the attached escapement wheel which :is situated beneath the plate 26 in the location previously described.

It 'is believed that the operation of the device will he obviously for .the most part from the foregoing description. The outer and longer arm of the lever 4! associated with the swing element is oscillated by the escapement bar '25, and through the pin :45 transmits movement in .opposite directions to the member 41 and to the extension 39 of one swinging bar I5 so as to cause the oscillation of the swinging element of the swing. While the member M has a generally reciprocating movement, it also has a slight up and down movement as the result :of the described mounting, and it can move up and down as required because of the engagement of its pin in the slot of the actuating arm. The spiral spring constantly exerts torque on the motor arbor, tending to rotate the escapement wheel in the same direction, and the escapement wheel exerts pressure against one of the pallets, but is restrained from movement b this pallet. The pallet eventually disengages and releases the wheel, however, permitting turning thereof until the other pallet comes into full engagement with and arrests the wheel, these movements causing the movement of the escapement bar under the influence of the swinging member or pendulum.

By the described construction it is possible to provide a toy swing in which the spring motor will cause oscillation of the pendulum element for a considerable interval of time before the rewinding of the motor is required.

The invention also provides an attractive toy which of compact and durable construction. The means intermediate the spiral spring and the pendulum element, which causes oscillation to be imparted to the pendulum element, is simple and substantial and operates in a satisfactory manner.

It is understood that in the drawings only one form of the device is shown, and that various changes can be made in the arrangement of parts and "in the structural details within the principles of the invention and the scope of the claims.
