JOHN BENJAMIN, OF SYRACUSE, NEW YORK.

BABY-JUMPER.

SPECIFICATION forming part Of Letters Patent N0. 626,521, dated June 6, 1899.

Application filed November 30, 1898. Serial No. 697,880. (No model.)

To an whom, it may concern.-

Be it known that 1, J OHN BENJAMIN, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in a Combined Baby'Jumper, Swing, and Rocker; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a combined babyjumper, swing, and rocking-chair and its object, among other things, is to provide a de vice of this character which will be convenient and efficient in use, simple in construction, and readily placed in operative position.

Further objects are to so construct the device as to permit a child to sit in an upright or inclined position while swinging or rocking and to provide means of peculiar construction and adjustment whereby the child may be securely held in the chair at all times.

To these ends the invention consists in providing a cliaiigthavin g legs pivoted to the rock ers, chair-sea and arms, said legs being retained in an upright position by means of a catch of peculiar construction, upon the release of which the chair may be forced into a reclined position.

The invention also consists in providing a peculiar arrangement of ropes for suspending the chair as a swing or jumper, said ropes also serving as means for retaining a guardbar of peculiar construction in position, said guard-bar being provided with clamps adapted to bind upon said ropes, and thereby lock said guard-bar in position to prevent the child from falling from the chair.

The invention also consists in the further novel construction and combinations of parts hereinafter more fully described, and illus trated in the accompanying drawings, showing the preferred form of myjinvention, in which Figure 1 is a perspective view of the complete device. Fig. 2 is a detailed side elevation showing the chair in upright position. Fig. 3 is a similar view showing the catch unhooked and the chair in inclined position. Fig. 4. is a modified form of base; and Fig. 5 is a front elevation of the guard-bar, showing the ropes therein, one clamped and the other loose.

Referring to said figures by letters of reference, A A are the rockers of any desired form, preferably constructed with a split or two-piece cross-bar a, as shown,within which, near the ends thereof, are pivoted the lower ends of the legs B of the chair. Said legs eX- tend upward a suitable distance and are pivoted near their upper ends to the arms 0 and at a point intermediate their length to the seat D of the chair, said cross-bars a, seat D, and arms G being parallel. Said seat D is of any desired construction and is provided with a transverse bar 61 thereunder, the ends of said bar projecting beyond the sides of the seat and secured to and supporting side strips D, free at their ends and bearing upward against eyes c or other suitable projections formed by the outwardly-extending portion of the pivots E of the legs and seat. Pivoted to the upwardly-extending portion of each of the rear legs B, at a point intermediate the seat D and arms 0, is a catch-bar F, extending across the side of the chair and overlapping the front legs. Said bars F are each provided at a point near their front ends with a guide F, adapted when the chair is upright to bear against the rear edge ofthe front leg. Said guides F likewise normally project downward into the slots f, formed by the side strips D and chair-seat I). At a point intermediate the ends of catch-bar F is pivoted a catch F preferably of the form shown, adapted to hook down over the end portions of the transverse bar 01 when the legs of the chair are upright, and thus retain the whole chair in an upright position.

It is of course obvious that the upwardlyextending portions of the rear legs may be connected by slats or in other suitable manner, forming a back G, as shown. The front legs of the chair, however, merely project slightly above the arms, as at b, said projections serving to prevent transverse movement of a guard-bar H, having shoulders it formed on its under surface near each end and abutting against the said projections b. It is obvious that, if desired, the projections b may be dispensed with and the guard-bar I-Isplaced directly upon the arms 0. Said guard-bar H is provided at each end on its upper surface only.

for the purpose hereinafter described.

Within the side strips D, directly under the eyes e, are perforations d.

of a rope J. Each of said ropes passes upward through eye 6, an eye f, formed on the; .pivot of the catch-bar F, and through a tube K, preferably formed of rubber, secured inan eye 0, formed on the rear pivot of arm 0. 5 Each of said ropes J then extends upward for .a suitable distance and is secured to a coiled 1 spring L or other suitable device provided with hook Z, whereby the same may be readily looped over orotherwise secured to any: suitable object. extends down-ward a sufficient distance and I is doubled upon itself, as shown at j,said doubled portion being inserted through ;an 5 eye com a front leg and through the per-fora- It is then kno tted,'as at 1 Each of the ropes J then tion d thereunder. j, and thereby prevented from being withdrawn.. The remainder of each of the ropes J is brought upward through an eye a on the front pivot of the arm-C and passed through a perforation J2, inthe guard-bar H at a point The free ends, of the ropes are'provided with hooks J which I may be secured to any part of the chair to;

"If desired, a toy-box M may be provided. I This is preferably secured to the guard-bar; H and may be provided on its under-surface with a dovetailed groove m for the reception o'f a str-ip N, projecting backward from the representation of the head of an animal or other object, as :O.

The rear perforation in each strip receives the knotted end After unhooking the ends of ropes J the guard-bar H 1 is drawn ;up along said ropes a suitable distance .and bar P is unhooked. The childcan then he placed in the chair without trouble. The ropesJ are then drawn through the bar.

may be dispensed with when the device is used ras a swing. If it is desired to incline the chair, catch F is unhooked from transverse bar (1, and the legs, back, and arms will then be free to swing back into the positionshown in Fig. 3, the guide F retaining bar]? in proper relation to the chair at all times.

It is,of course, obvious that the ropes may be looped up over the back or placed in other suitable position if it is desired to use the invention as a rocker.

In the foregoing description I have shown the preferred form of'my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing the wad-vantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus described my invention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is

1. The combination of the base,legs pivoted thereto, a seat and varms-pivoted tosaid legs, a transverse bar on said seat,aside strip secured to said bar, anda catch-bar, secured to the backof :the chair and a :h'oo'k,gsecured to said catch-bar, projecting into a slot formed by said seat and side strip, adapted to engage with said transverse bar and retain the chair in an upright posit-ion, substantiallyas described.

2. The combination of the legs, the rockers and seat and arms pivoted thereto, a catchbar pivoted to the back of the chair, a catch pivoted to said bar and adapted to engage with a transverse bar secured to said seat,

: and a side strip. secured to said transverse As an additional means for seen-ring a child from accident, as by falling, a second bar, as P, maybe pivoted to one side of the chair. and secured to the oppositeside by means of bar and forming a slot between said strip and seat, and a .guide on the 'catch bar, all substantially as described.

3. lhe combination, with the chair, of a guard-bar having perforations therein, cam- Ahinged fo'ot-rest Q is provided. Said rest is pivoted at-each side to the rocker-bars a, andshould be raised when the chair is used as a roekerand lowered when otherwise used.

In Fig. 4-1 have shown a platform whichf maybe substituted for rockers, if it is de-i sired to use the device as a swing or jumper Said platform is pivotallysecured to the legs, asare the rockers, and may be of levers on said bar and shoulders adjacent to said cam-levers; of ropes passing through said perforations and adapted to be'clamped between said cam-leversand shoulders, and means, as-described, for securing said ropes to the-chair, substantially as described.

4:. The combination, in a combined babyju'mper, swing and rocker, of legs pivoted to the rockers, seat, and arms, means, as described, for retaining said chair in an upright position, side strips secured to said seat, ropes secured in said side strips, springs secured to said ropes, and a guard-bar strung on said ropes, said bar having means, as described, for preventing movement of the ropes therein, all substantially as described.
