COMPLETE SPECIFICATION.
Improvements in Baby-jumpers.
I CLARENCE LESLIE BARNHART, of 407 North Second Street, Flint in the
County of Genessee and State of Michigan, United States of America, Inventor
do hereby declare the nature of this invention and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
The object of the invention is to provide an efficient, spring-actuated baby-
jumper, which is simple and durable in construction and effective in operation.
The invention consists in the novel construction and combination of parts, as
hereinafter particularly described and defined in the claims.
Reference is to be had to the accompanying drawings forming a part of this
Specification, in which similar letters of reference indicate corresponding parts in
both the figures.
Figure 1 is a perspective view of a baby-jumper embodying my invention; and
Figure 2 is a detail end view of the crib and a portion of its supporting
hanger.
In constructing a baby-jumper embodying my invention I provide a base A, of
skeleton form, comprising a front bar a and the side bars a', the same being provided
with a suitable number of casters B, to enable the jumper to be readily moved from
place to place as desired.
At the rear end the side bars a' of the base A are projected upwardly and
inwardly as at a', the upper meeting ends being welded or riveted to and serving to
support a standard A¹.
At its upper end the standard A' extends forwardly to form the overhanging
arm A, the extreme outer end of which lies in about the horizontal plane and
terminates in an eye or a hook a³.
From the outer end of the arm A as thus formed, the hanger C, having an
eye c' at its upper end, is suspended through the medium of a spring D of novel
construction, the crib E, being held on the horizontally ranging lower end c of the
hanger C.
The crib E, is preferably made of light or thin material, and that it may be thus
made, the connection with the arm c, is effected through the medium of a screw or
screws F, passing through a block E¹ or an equivalent enlargement interposed
between the arm c and the bottom of the crib, the said block, or its equivalent, thus
serving to strengthen the connection at the point of strain.
The spring D is of the spiral variety and is formed of two strands of wire d, d¹,
the terminals of which are joined to form loops d², at the ends of the spring, which
engage the eye a of the standard, and the eye of the hanger.
With this form of spring increased strength and increased elasticity is obtained,
and the crib will be kept in motion for an increased length of time.
The casters B, on the base erable the jumper to be moved about with ease, and
the whole structure is light, durable and efficient, and involves a comparatively
small cost in its manufacture.
By the term crib as herein used, I mean any device for holding or supporting
the child, such as a chair, a frame, or straps for holding the child.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination, in a baby-jumper, of a base supporting a standard from one
end thereof the standard having an overhangingo arm and a crib sunnorted from said

page_text: overhanging arm, the connections between. the crib and said arm including a spring,
substantially as described.
2. The combination, in a baby-jumper, of a skeleton base having the sides
thereof extending upwardly and inwardly and supporting a standard, the latter
having an over-hanging upper, end, as spring depending from said arm, a hanger
depending from said spring, and a crib. carried by said hanger,, substantially as
d'escribed.
3. The combination, in a baby-jumper, of a standard having an overhanging arm
and a base provided with casters, a spring depending from said arm, a hanger
depending from said spring, and a crib supported on said hanger, substantially as
described.
4. The combination, in a baby-jumper, of a standard having an overhanging arm,
and a base provided with casters, a spring depending from said overhanging arm, a
hanger depending from said spring and formed with a horizontally ranging lower
end, and a crib secured to said horizontal arm and having a block or enlargement
at its side at the point of connection with the hanger arm, substantially as
described..
5. In a baby-jumper, the combination, with a suitably supported standard, of a
crib suspended therefrom, the connection including a spring formed of double strands
of wire, substantially as described.
6. In a baby-jumper, the base A formed at its rear end with upward inclined
bars, which terminate in and support a vertical, overhanging standard, substantially
as herein shown and described.
7: In a baby-jumper, the base A, having the front cross bar a, and having its side
arms a¹, continued inwardly and upwardly to form the standard A', the said standard
overhanging at its upper end as at A², a spiral spring D suspended from said over-
hanging end, a hanger arm. C, suspended from said spring, and formed with a rigid
horizontal seat which extends and is supported at one side of said hanger arm,
and a crib E secured to said horizontal seat, all in combination, substantially as
described.,
