ERNEST E. HUMPI-IREY, or LINCOLN, NEBRASKA ADJUSTABLE BABY-JUMPER.

To all whom it may concern:

Be it known that I, ERNEST E. H'UMPHREY, a citizen of the United States, residing at Lincoln, in the county of Lancaster and State of Nebraska, have invented an Improved Adjustable Baby-Jumper, of which the following is a specification sufliciently clear to enable those skilled in the art to which it appertains to make and use the same.

Its object is he production of a baby jumper which is adaptable to a baby of any weight and in which the jump of a baby of any weight is conveniently and safely capable of a wide variation and of a form not likely to mar furniture or woodwork, adapted to be used in comparatively restricted space, and which can be economically made and placed on the market at a comparatively low price. These purposes are attained in my invention by certain novel construction and combination of parts and materials which will be hereinafter described and claimed.

My invention is illustrated in the accompanying drawings, which form a part of this specification and in which drawings similar characters of reference refer to similar parts.

Figure 1, represents a vertical elevation of my device. Fig. 2, represents a crossseotional view of my springs on the line (L 277 C 2'77 I prefer the following forms of construction though I reserve all rights of variation therefrom within its general purpose and conception.

I make my invention with two spiral steel springs preferably though other suitable metal may be used. These springs a and b as shown in Fig. 1 of my drawing, I make of different sizes, the smaller spring b being adapted to freely slide within the larger spring a. I make the spiral portion of the larger spring a shorter than the same portion of the smaller spring Z) so that the spiral portion of the smaller spring 7) normally projects slightly beyond the ends of the spiral portion of the larger spring a. I form each end of the larger spring, a into a longitudinal, elongated loop 0. I position the loops 0 of the larger spring a at one side of the line of the central opening in the large spring a to allow free independent Specification of Letters Patent.

extension of the small spring b. I form each end of the small spring 6 into a small, longitudinally extending loop, CZ. I connect the upper loops 0 and d by a metal 8, which is lettered m in drawing, the upper portion of which 8, I form into a hook adapted for attaching to an eyelet or other top support. The lower loops, 0 and (Z I securely shackle together by the section of open link chain, c by attaching one end of the chain to each loop respectively, to permit free and independent motion of each spiral spring.

I make a carrier connector, f of the general form of a letter 8, however with the lower portion thereof closed and the upper portion forming a hook shaped member adapted to snugly engage and be interchangeable in the opening in any link of the chain c I make my carrier supports, g each preferably from a single strip of strong denim, which for additional strength and wearing qualities I fold together and sew with a central, longitudinal seam. I use a plurality of carrier supports which I separate, approximately midway their length by a metal spreader, h which I make of suitable metal wire, portions of which spreader, I bent at approximately an angle of forty five degrees and at uniform distances apart on same to form rests, h upon which I attach the carrier supports so as to directly oppose the horizontal strain of the supports on the spreader. I attach the upper end of each carrier support to the metal 8, f, the central part, of each support to its rest, 71. on the spreader it so that the spreader is suspended horizontally between same, and I attach the lower end of each carrier support, at uniform distances apart to the main portion of the baby carrier, 7' so that it is suspended horizontally thereby. I make the carrier also of strong denim, of a plurality of thicknesses, sewed together to give strength and durability, in two portions. The main portion of the carrier I make in the form of a wide waist band for a baby, j and adapted to hold the baby and furnish support for its body. I make a second portion of the carrier, is in the form of a narrower band having a central part, Z formed into a padded roll to act as a spreader and furnish a comfortable undersupport for the baby. I attach each end of the part is to opposite side band portion, j so as to depend therefrom as shown in the drawing.

The utility of my construction Will be at once apparent.

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

In a device of the character described, in combination, two spiral springs, said springs being made one larger than the other, the smaller spring being adapted to freely slide within the larger spring, the spiral portion of the smaller spring being made slightly longer than the spiral portion of the larger spring, each end of each spring terminating in a longitudinally extending loop, the loops on the ends of the larger spring being positioned at one side of the central opening of the spring, a metal 8, the loops on one end of each spring being attached together by the lower, portion of the S, a chain shackle, said shackle being composed of open links and having one of its ends attached to the lower loop on the small sewed, a support spreader, said spreader being made of suitable wire in the general form of a continuous square but having its corners angled at forty five degrees from its sides, and a carrier, said carrier composed of fabric folded and sewed lengthwise forming a wide Waist band, and an under support depending therefrom and having a padded roll midway its length.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.

ERNEST E. HUMPHREY.
