tlhlllTEi) STATES FRANK ROBERT THALKEN, OF CONEY ISLAND, BROOKLYN, NEW YORK.

PORTABLE JUMPING TREE.

Application filed June 7, 1922.

To (ZZZ trim/)2- it may concern:

Be it known that I. FRANK Ronnn'r TI-IAL- nnx, a citizen of the United States, residing at (Ioney Island. Brooklyn. in the county of Kings and State of New York, have invented certain new and useful Improvements in .lortable Jumping Trees, of which the following is a specification.

This invention relates to a toy of. the type providing a resiliently supported seat which permits of a child jumping up and down while seated thereon, the invention having for an object to provide a novel form of toy of this type For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the vari ous novel features of the invention are more particularly set forth.

Fig. 1 of the drawings is a perspective view of a toy constructed according to my invention.

Fig. 2 is a horizontal sectional view thereof. omitting the seat back, this view being taken on the line 22 of Fig. 3.

Fig. 3 is a vertical sectional view thereof taken on the line 3-3 of Fig. 4,

Fig. 4 is a vertical sectional view at right angles to Fig. 3 and taken on the line r% of the latter.

Fig. 5 is a horizontal sectional view showing a modified construction, this view being 5 of Fig. 6.

Fig. 6 is a vertical sectional view of this modification taken on the line 6-6 of Fig. 5.

Fig. 7 is a horizontal sectional view indicating a further modification.

Fig. 8 is a perspective view showing another modification.

Fig. 9 is a horizontal sectional view thereof taken on the line 9-9 of Fig 1.0.

Fig. 10 is a vertical sectional view thereof taken on the line 10-1O of Fig. 9.

Fig. 11 is a horizontal sectional View, taken on the line 1111 of Fig. 12, of a further modification.

F in". 1.2 is a fragmentary vertical sectional view thereof taken on the line 12-12 of Fig; 11.

Fig 13 is a horizontal sectional view. taken on the line 13-13 of Fig. 14;, showing another modification.

F ig. 1.4 is a vertical sectional view thereof taken. on the line 14.-1.4; of F ig. 1.3;

Serial No. 566,572.

Fig 15 is a horizontalsection showing a further modification.

Referring now to the embodiment of the invention illustrated in Figs. 1 to at my improved toy comprises a platform or base 10 which may be mounted on castors ll. On one end of this base is a housing 12 provided on its forward side with a slot 13. Extend ing from top to bottom in this housing is a fixed guide member 01' poit 15 which is here shown as formed with a slot 16 extending from the top thereof to a point a short distance from its bottom.

Slidably engaging over this guide member is a crosshead 17 from one side of which a rigid bar 18 projects horizontally through the slot in the housing. This bar has a seat .19 on its outer end which may h ave a back 20 in the form of a manikin as indicated in F 1. The crosshead 17 is provided with upper and lower anti-friction rollers 21 which engage the guide on opposite sides thereof. Secured at one end to the bar 18 is a cable 22 which passes upwardly over a pulley 23 mounted in the upper end of the guide 15, and then downwardly to connect at its opposite end to a coiled tension spring 2st located in. the lower end of the slot 16 and attached to the bottom end wall of the latter. The cable 22 may be passed through apertures 25 in a block 26 fixed to the guide under the pulley 23.

In the modification shown in Figs. 5 and 6 the guide is formed by two pairs of posts 30 between respective pairs of which are located pairs of vertically spaced rollers 31 carried by a crosshead 32 from which the seat carrying bar 18 projects.

In the arrangement shown in Fig. 7 the guide is formed by a pair of posts 33 having grooves in their opposite sides in which engages rollers 34; carried by a cross head 35 from which a seat-bar 18 projects, the crosshead being supported by the means above described.

In the construction shown in Figs. 8, 9 and 10 the guide member is in the form of a round post 37 and the crosshead comprises a sleeve 38 fitting slidably over the post and having integral therewith a projecting seatbar 18. The sleeve 38 is provided at upper and lower ends with anti-friction rollers 39 which bear on opposite sides of the post 37 The crosshead is here supported by a coiled compression spring 40 which surrounds the post 37 under the crosshead. The seat-bar til) 18 may have mounted thereon a seat in the form of a horse as indicated at 41 in Fig. 8. The crosshead 38 has integral extensions 42 engaging in grooved guide elements a3 on the housing.

In the modification shown in Figs. 11 and 12 the guide element comprises four round posts 44 engaged by rollers 45 on a crosshead-block 46 which has lateral extensions 47 engaging in grooved elements L8 in the sides of the housing. The crosshead has an integral seat-bar 18 and is supported by a coiled expansion spring located thereunder 49.

In the modification shown in Figs. 13 and 14 the guide element comprises four round posts 52 engaged by upper and lower concave rollers 53 mounted on crosshead-block 54; which has an integral projecting seat bar 18. The resilient mounting in this case is provided by a coiled spring 55 located in a horizontal cylindrical casing 56 fixed in the upper part of the housing 12, this Spring being connected at one end to said casing and at its opposite end to a shaft 57 journaled in the latter and having a projecting end on which is fixed a drum 58. A cable 59 is secured at one end to the bar 18* and at its opposite end to the drum 58, on which latter it is adapted to wind to raise the seat.

In the modification shown in Fig. 15 the guide element comprises the vertically grooved plates 61 arranged on opposite sides of the housing 12 and having their grooves engaged by rollers 62 on a crosshead 63 hav ing in integral seat-bar 18. The resilient seat supporting means may be the same as shown in Figs. 13 and 14.

laving thus described my invention what I claim as new and desire to protect by Letters Patent of the United States is as follows:

1. A toy of the type described comprising a platform, a housing supported on one end thereof, a vertical guide in said housing, a crosshead slidable on said guide, a seat fixed to said crosshead, and a spring resiliently supporting said seat and crosshead.

ii toy of the type described comprising a platform,a housing supported thereon and formed with a vertical slot in its wall, a vertical guide in said housing, a crosshead slidable on said guide, a seat-bar projecting rigidly from said crosshead through the said slot, and a spring supporting said crosshead. 3. A toy of the ty e described comprising a platform, a housing supported on said platform, a vertical guide in said housing, a crosshead slidable on said guide, upper and lower antifriction rollers on said crosshead engaging respectively the opposite sides of said guide, a seat fixed to said crosshead, and a spring resiliently supporting said crosshead and seat.

' In testimony whereof I have affixed my signature.

FRANK ROBERT THALKEN.
