LOUIS THEODORE TURMELLE, OF LAKE ETCHEMIN, QUEBEC, CANADA.
Specification of Letters Patent.
Application filed December 10, 1910.
Patented Apr. 11, 1911.
Serial No. 596,679.
To all whom it may concern:
Be it known that I, LOUIS THEODORE TUR- MELLE, resident of Lake Etchemin, county of Dorchester, Province of Quebec, Dominion of Canada, laborer, having invented certain new and useful Improvements in Automatic Swings, do hereby declare that the following is a full, clear, and exact description of the same.
The invention relates to improvements in automatic swings, as described in the present specification and illustrated in the accompanying drawings that form part of the same.
The invention consists of the novel construction and arrangement of parts whereby the oscillation of the swing body is main tained by the continuous rotation of the shaft, suitably journaled in the supporting frame.
The objects of the invention are to devise a swing for pleasure resorts and gardens that may be operated safely by children and those inexperienced wit-h mechanical and electrical machinery, and to provide a simple and reliable mechanism and a safe structure for the purpose.
In the drawings, Figure 1 is a perspec tive view of the structure partially broken away at the upper end, showing the operating mechanism. Fig. 2 is an end elevation of the swing. Fig. 3 is an enlarged perspective detail of a portion of the frame and a spring pawl. Fig. 4: is a detail of the toothed wheel and its spring connections to the shaft and the pulley mounted on the shaft.
Like numerals of reference indicate cor responding parts in each figure.
Referring to the drawings, 1 are the uprights of inverted V-shaped form.
2 are the cross bars supporting the platform 3.
1 is a rectangular frame supported at the upper end of the uprights l and extending beyond said uprights at one side thereof.
5 is a cross beam extending between the side beams of the frame 41 and rigidly secured to one of the uprights 1.
6 is a central longitudinal beam between the cross beam 5 and one of the end beam of the frame 4.
8 is the top beam of the swing having shaft extensions therefrom journaled in the bearings 9.
10 are the vertical side bars of the swing rigidly secured to the top beam 8 at their upper ends.
11 is a seat firmly secured to thevertical bars 10.
12 is the foot-board secured to the bottom of the vertical bars 10.
13 is a wire secured to the eye 1& at the rear end of the platform 3 at one end and having at the other end the loop 15.
16 is a foot lever pivotally secured to the foot-board 12 toward the front edge thereof and having a hook projecting therefrom engaging the loop 15 for retaining the seat to its rear position so that on pressing the said lever 16 with the foot, the looped wire or rope 18 is released from engagement with the hook 17 and the swing set in motion.
18 are bearings supported on one of the side beams of the frame 1 and the beam 6 respectively intermediate of the lengths thereof.
19 is a shaft journaled in the bearings 18.
20 is a sleeve mounted on the shaft 19 and having the circumferential slots 21 there through.
22 is a toothed wheel fixedly mounted on the sleeve 20 between the slots 21. r
23 are spiral springs at one end extending through the slots 21 and secured to the shaft 19 and at the other end secured to the side faces of the wheel 22, intermediate of the distance between the center and the teeth thereof.
241 is a pulley fixedly mounted on the shaft 19 beyond the inner one of the bearings 18.
25 is a motor supported on the end beam of the frame 4:.
26 is a pulley mounted on the motor shaft, operatively connected with the pulley 24 by the belt 27 said transmission of power from the motor to the shaft 19 being designed to impart a comparatively slow motion to said shaft 19.
28 is an arm extending laterally from and fixedly secured to the top beam 8.
29 is a pivoted lever secured to the outer end of the arm 28.
30 is a spring secured to the pivoted lever '29 and the arm 28, and exerting a backward pull on said lever 29.
31 is a guiding plane rigidly secured to the frame 4 and engaged by the back of the head of the lever 29.
32 is a spring-held locking pawl pivotally secured to a strut 7 and normally engaging the tooth of the wheel 22, said pawl bein released from engagement with said whee at each upward movement of the pivoted lever 29, said pivoted lever being a releasing lever to permit the rotation of the wheel 22 to the extent of one tooth, therefore, at each forward swing of the seat 11, assaid releasing lever 29 makes an upward movement and releases the pawl 32, thus allowing the wheel 22 to rotate and making that rotation intermittent to correspond with the oscillation of the said seat. The pivoted lever 29 has a recess 33 to receive the tooth of the wheel 22, which is released from engagement with the pawl 32, consequently as the seat begins to swing baclrwardly, the lever 29 moves downwardly, thereby traveling with the rotation of the wheel, the spring pawl returning to engagement with the wheel at the next succeeding tooth.
34 is a lever pivotally secured to the cross beam 5 and connected to the stopping and starting mechanism of the motor by the rods 35 and 36 respectively.
37 is a cord at its upper end connected to one end of the lever 34 and at its lower end having the handle 38, said cord extending through a suitable hole in the top beam 8.
39 is a cord at its upper end secured to one end of the lever 34 and having at its lower end the handle 40, said cord extending through a suitable hole in the cross top beam 8.
The cords 37 and 39 extend downwardly to within easy reach from the seat 11, consequently the passenger may readily control the operation of the motor from his position on said swing.
In the operation of the invention, the passenger seats himself comfortably and pulls the cord for starting the motor and presses his foot on the lever 16, and the seat, being in its extreme rear position, swings forwardly. The pivoted lever 29 slides upwardly, being guided by the plane 31 to the pawl 32, releasing said pawl from engagement with a tooth of the wheel 22. The shaft 19, which is rotating through its connection with the motor 25, exerts a pull on the springs 23, thus when the tooth is released from the pawl 32, the wheel springs forward to the extent of one tooth, and as the pivoted lever 29 has taken the place of the pawl 34, said pivoted lever is forced downwardly and consequently the arm 28. The said arm 28 being rigidly connected with the top beam 8, the seat is swung back to its rear position. This operation is continuous while the motor is going, as by the continual rotation of the shaft and the prevention of the rotation of the wheel by the pawl 32, the tension of the springs 33 is maintained sufficiently to impart to said wheel an intermittent movement and this intermittent movement secures the backward swing of the seat.
What I claim as my invention is:
