MNTED STTEES CHARLES S. TAYLOR, OF FRESNQ, CALIFGRNIA.

JUVENILE J'UMP SEAT.

Application filed .Tune 1, 1925.

My invention relates to playthings for children and has for its principal object a novel jump seat adapted to give a child both pleasure and healthful exercise. Lesser objects are simple construction, cheapness, j iortability, adjustability to suit children of various weights and sizes, and withal a device of this kind which will be free from danger to small children using it.

l attain the objects mentioned by the jump seat construction shown in the accompanying drawings and in which Figure 1 is a Iside elevation of the device with seat in normal position, and in dotted lines the seat is shown in lower position as though depressed by the weight of a child.

Figure 2 is a plan view looking down on Figure 1, and Figure 3 is an end view of Figure 1.

'In further detail my jump seat con-struction comprises a lower -skeleton frame adapted to be placed upon the floor or ground 1 and having a pair of longitudinal members 2 lying on the ground and at one end being joined to a pair of vertically arranged members 3 forming an upright. This upright is rigidly secured to the horizontal members and firmly braced thereto by angularly disposed rods 5.

The frame is preferably constructed of light angle bars, and the rear ends are conveniently curved as at 2 to avoid sharp corners.

The vertical members 3 diverge outwardly at their lower ends, and the horizontal members 2 lie parallel to one another in spaced relation and are tied in this arrangement by one or more cross members as shown at 6 and 7, the cross members being securely riveted to the horizontal members.

The upper ends of the upright members 3 are best made continuous as indicated at S or otherwise secured together, and are preferably bent so as to lie parallel for a short distance near their upper ends as shown in Figure 3, and a hole is drilled through the parallel portions to supportthe main pivot bolt 9 of the seat supporting bar or upper frame 10.

The seat supporting bar or upper frame 10 extends horizontally from the upright members 3, and while it may be of any suitable material, such as hard wood, or metal, it is here shown as made of an inverted channel iron with a seat 11 transversely ar Serial No. 34,109.

ranged on the outer or free end and slidably adjustable along the bar.

ln front of the seat, and also slidably adjustable along the bar 10 is a pair of handles or h ndle bar 12 adapted for gripjiing by a chil-d sitting on the seat and straddling the bar.

At the opposite end the upper frame or bar 10 has a downwardly extending arm 13 braced to the horizontally extending portion by a pair of gusset plates 14e through which the pivot bolt S) entends so that the bar 10 is tree to oseillate at its outer end along the dotted are 15, though it is normally forced to the high position as shown in full lines in Figure 1 by a spiral spring 16 pulling on the lower end of the arm 13.

rFhis spring 16 is preferably enclosed in a tubular working barrel or short section of pipe 17 secured to the frame cross member 6 by the Istrap 24, or otherwise.

rEhe spring barrel 17 has a cap 13 secured to one end, and against the inner face of which the compression spring 16 reacts.

A. bolt rod 19 passes loosely through a hole in thc cap and entirely through the spring and is provided at the end with a nut 2O and washer 21 bearing against the end of the spring so that the compression of the spring may be varied through means of a socket wrench introduced into the open end of the pipe.

At the outer end the rod 19 is formed with an eye Q2 and is loosely linked to the end of the arm 13 by a link 23 so that in forcing the bar 10 downward as through means of a child upon the seat 11, the arm 13 will swing to the left and by pulling the link 23 and rod 1.9 will compress the spring against the cap 13 of the pipe.

The amount of spring compression is controlled by the nut 2O to just balance a rider on the seat when in lower dotted position so that the child can get a good kick upon the ground for an upward ride. r1`he spring may be further adjusted to determine the maximum rise of the bar 10 by adjusting the pipe at the desired position in the clamp 24.

The amplitude of the oscillatory move-A ment may be reduced by sliding the seat and handles nearer to the pivotal support of the bar 10, and the handles affording a Isecure grip for a youngsters hands prevent the child from falling.

In fact, a years test of one of these devices, which though used with considerable violence b v children, was without a single acci dent, thus demonstrating its entire practicability and safety.

In considering the invention as above specified and shown in the drawings, it will be evident that the device may be considerablyv modified both in frame construction as well as in arrangement of the spring, yet

carry out the objects, of the invention, and

any snch inodilications as come Within the spirit oit' the invention are sought to be covered in the appended claims.

I claim:

l. ln a juvenile jump seat of the character described, a supporting frame having an upright, a horizontally disposed seat oarruving arm pivoted to the upright and spaced above the supporting frame and said arm having a downwardly extending portion, a spiral compression spring mounted on the frame, a' tubulaihonsing covering the spring and supporting one end thereof against compression, and a rod connected to said downwardly extending portion ol the "L arm extending through the spring and having adjustable means thereon bearing against the opposite end of the spring for compressing the spring within said tubular housing upon downward movement of the arm.

2. In a juvenile jump seat of the character described, a supporting frame having an upright, a horiZonJ-Lali)v disposed Seat carrying arm pivoted to the upright and spaced above the supporting frame, said arm having a downwardly projecting portion, a compression spring mounted on the frame and provided with means for retaining it in case of breakage, and means extending from the downwardly projecting portion oi the arm engaging the spring for compressing the saine upon downward movement of the arm.
