OBSERVATION-SWING.

Specification of Letters Patent.

Patented Jan. 14, 1908.

Application filed November 9. 1907. serial No. 401.421.

T 0 all whom it may concern:

Be it known that I, WINFIELD S. RrToH, a citizen of the United States, and a resident of the city of New York, borou h of Brooklyn, in the county of Kings and gtate of New York, have invented a new and Improved Observation-Swing, of which the following is a full, clear, and exact description.

My invention relates to mechanism used for purposes of observation and amusement, and comprises more articularly a type of swing having some 0 the characteristlcs of an observation wheel.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of my observation swing complete, showing the passenger car in its most elevated position, and also indicating in dotted lines a portion of the movement of the rockers supporting the car; Fig. 2 is a substantially central vertical section through Fig. 1, showing in elevation the rockers supporting the car, and also. supporting the counterweight for the car and gearing for shifting this counterweight at will Fig. 3 is a fragmentary lan view of a portion of the tracks used or supporting the rockers, this view also showing the hand-operated mechanism for releasing the rockers; Fig. 4 is an enlarged fragmentary section showing the hand'wheel and parts operated thereby for securing the counterweight at different elevations; and Fig. 5 is an enlarged fragmentary erspective of the latch used for holding rigi ly in osition the hand crank used in operating t e mechanism for shifting the counterweight.

Beams 6 are mounted upon supports 7, and connected with these beams are brace rods 8 supporting tracks 9 having parallel.

tread portions 10, as will be understood from Fig. 3. Brace rods 10 and cross beams 10 are provided for the purpose of securing the tracks rigid in relation to each other. A pair of rockers 11 have each a substantially elliptical form, as indicated in Fig. 1. Each rocker 11 is provided with a pair of rooves 12 parallel with each other and cords 13, 14 are provided and so disposed as to fit loosely into these grooves. These cords are fastened at their outermost ends, as will be understood from Fig. 3, and the cords are partially wound upon the rockers 1 1 and terminate in loops 13 and 14 whereby they are rigidly secured to the, rockers (see Fig. 1).

The rockers contain s okes 15, 16, 17, 18, 19 mounted in a central hub 20. Connected with the rockers upon the inner faces thereof are rails 21, each having the form of a rigid bar. A counterweight 22, is provided with rollers 23, which on a e opposite sides of each bar 21, as wil e understood from Figs. 1 and 2. Each rail 21 is en aged at its outer end by a wire cable 24, w ich serves to brace it rigidly in position, the ends of the wire cables 24 being connected with cross rods 25. These cross rods together with other cross rods 26 connect the rollers firmly together.

Brace rods 27 are provided with turnbuckles 28 and cross each other, and are connected with the brace rods 25, 26, as indicated in Fig. 2. Mounted centrally upon the counterweight 22 is a rod 29, which extends upwardly through a collar 30, supported upon a cross beam 31. This collar is provided with jaws 32, 33, the jaw 32 being provided with a threaded hole, and the jaw 33 being provided with a smooth hole 37 in registry therewith, as will be understood from Fig. 4. l

A rod 34 is provided with an annular bead 35 integral with it, and also provided with a threaded portion 36, this threaded portion 36 engaging the threaded hole of the jaw 32, while the smooth portion 35 extends loosely through the smooth hole 37. A hand wheel 38 is mounted upon the rod 34 and used to turn the same, and a bearing 39 is provided for the rod 34. By turning the wheel 38 the jaws 32, 33 are moved toward each other, or allowed to spring apart, as the case may be, thereby tightening or loosening the split collar 30 relatively to the rod 29.

Two racks 40 are connected rigidly with the counterweight 22 and extend upwardly from the ends thereof. Pinions 41 engage the racks 40 and are mounted upon a revoluble shaft 42. A hand crank 43 is mounted upon the rod 42 and used for the purpose of turning the pinions 41, thereby raising or lowering the racks 40. By turning the hand wheel 38 so as to loosen the collar 30 and then turning the hand crank 43 so as to raise or lower the counterweight 22, the operator may bring the counterweight into any desired position within certain limits. This being done, he again turns the hand wheel 38,

by dotted lines in 1 1, t

and in so doing tightens the collar 30 upon the rod 29 while securing the counterweight in the desired position and enabling the counterweight to be supported directly from the collar 30 and beam 31.

This avoids all necessity for supporting the counterweight from the pinions 41 and racks 40.

In order to avoid possibility of premature retrograde motion of the hand crank 43, a latch 44 (see Fig. 5), having the form of a fork, is provided for the purpose of engaging the hand crank. This latch is mounted upon a pivot 45 and is provided with a lug 46 which engages a pin 47 fixedin the spoke 19 and serving as a limiting stop for the latch. In order to be able to turn the hand crank 43, the operator raises the latch 44 and after the movement of the hand crank iscompleted, he lowers the latch so as to bring it into engagement with the hand crank 43. The friction of the pivot pin 46 may be relied upon to prevent accidental movement of the latch 44.

A pin 48 (see upper portion of Fig. 1) is mounted upon one of the rockers 11, and an aperture 49 is cut into one of the rails 9 in such position that the pin 48 may be brought into registry with this aperture, as indicated by dotted lines in Fig. 1. A dynamometer scale 50 is mounted on the beam 6 upon a pivot 51, and is connected by a'spring 52 to the adjacent rail 9. The s ring 52 tends to draw the scale toward the eft, according to Fig. 1. An extensible latch 54, forming a part of the scale, is adapted to be engaged by the pin 48 and is normally held against a pin 53, carried by the rail 9.

, When the parts are in their normal posi tion, as indicated in Fig. 1, the pin 48 of the rocker, by engaging the upper end of the extensible latch 54, will force the latter slightly to the right according to Fig. 1, so that the pin 48 may catch under a portion of the latch 54, and to facilitate this purpose, the upper end of the latch 54 is beveled; A rod 55 is pivotally connected with the scale 50 and is rovided at one of its ends with a link 56. A and lever 57 is provided with a pin 57 which extends through the link 56. The hand lever 57 is mounted upon a pivot 58 secured to the framework. Aratchet 59 of arcuate form is en aged by a pawl 60 under control of a hand e 61. A passenger car 62 is provided with seats 63 and is suspended from pivot pins 64 mounted upon the rockers. A cam lever 65 is mounted upon a pivot 66 and is provided with a portion 67 extending below the tracks 9. A rod 68 is pivoted to the portion 67 and is also pivoted to a hand lever 69. By rocking the hand lever 69 the cam lever 65 may be caused to oscillate. When the rocker is in the position indicated e pin 48 engages therefore,'the dethe cam lever 65. en,

vice is at rest and the pin 48 lodges against from experience the latch 54, as above described, the operator, by releasing said latch by aid of the hand lever 57, and at the same time pulling upon the hand lever 69, may start the rocker into motion with a considerable degree of impetus.

My invention is used as follows: The rockers are rocked or turned as indicated by dotted lines in Fig. 1, so that the latch 54 engages the pin 48 and holds the rockers in the position indicated by dotted lines in the figure just mentioned. Passengers now take their seats in the car 62 which hangs at a convenient level for this purpose. notes from the dynamometer scale 50 the approximate weight of the passengers aboard and adjusts the counterweight 22 accordingly. It will be understood that this weight should always be so adjusted that the observation car will rise and pass over the center of movement and in doing this will not carry the observation car at a dangerous rate of speed on the one hand, and will not be too tardy on the other. The operator soon learns how to adjust the counterweight quickly so as to accommodate a given amount of tonnage carried in the observation car.

The operator Having adjusted the Weight, he prevents any further movement of the latter by securing the hand crank 43 by aid of the latch 44 (see Fig. 5) as above described. The operator next releases the lever 57 by withdrawing the pawl 60 from the rack 59, and by turning the lever to the right, according to Fig. 1, he draws the latch 54 out of engagement'with the pin 48. This releases the rockers and the observation car swings upward and over toward the left, oscillating back and forth several times. It depends upon the program whether the observation car 62 is allowed to come to a state of .rest in the position indicated by full lines in Fig. 1. The rocking may be continuous, if desired, the operator merely grasping any portion of either one of the rockers and causing the rocking to take place after the manner of a swing, or he may simply release the rockers as above described and allow the car to come to a state" of rest in its uppermost position.

The operator, by swinging the hand lever 69 back and forth, may cause the rocker to oscillate for an indefinite length of time, all strokes of the rocker being of substantially equal length.

I do not limit myself to any particular size or dimensions for the car, nor to its use in places of amusement, for obviously variations in such matters may be made without departing from the spirit of my invention. Neither do 1 limit myself to any particular material, nor to any exact'shape for any part except as may be specified hereinafter in my claims.

claim as new and desire to secure by Letters Patent:
