ADJUSTABLE SPRING FOR BABY-CARRIAGES.
SPECIFICATION forming part of Letters Patent No. 643,365, dated February 13, 1900. Application filed May 4, 1899. Renewed January 18, 1900i Serial No.1,921. (No model.)
T0 at whom it may concern.-
Be it known that I, GEORGE A. SMITH, a subject of Her Majesty the Queen of Great Britain, residing at Alberni, county of Vancouver, Province of Manitoba, Canada, have invented certain new and useful Improve ments in Convertible Springs and Baby-Jum pers; and I do hereby declare that the following is afull, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.
This invention relates to baby-jumpers to be used in connection with baby-carriages, and has for one object to provide a spring for a perambulator, which can be quickly and easily converted into a baby-jumper.
A further object is to provide a perambulator with a baby-jumper, which is simple and economical in construction and operation, and which may be readily applied and removed by any unskilled person.
To these ends the invention consists of a convertible spring and babyjumper constructed and operated substantially as hereinafter illustrated and described, and defined in the appended claims.
Referring to the drawings, in which similar letters refer to similar parts in all the views, Figure 1 represents a side View of the improvement applied to a baby-carriage, the body of which is in section and partly broken away. Fig. 2 is a similar view showing the invention as it appears when used as an ordinary carriage-spring. Fig. 3 is a view in perspective of the double hinge detached, showing details of construction.
In the drawings, A represents the body por tion of a babycarriage or perambulator,which may be of any ordinary or preferred form, and A is the frame or runninggear upon which the said body portion is supported. To the under side of the rear of the body portion is secured a duplex hinge a, having sockets a, a and a for the hinge pintle or bar I) or I), attached, respectively, to the end of the spring B and B. I
The improved spring is constructed of two parts, an inner and outer spring, or the spring proper or ordinary carriage-spring B and the jumper-spring B, which are united by an ordinary hinge-joint by the pintle b. The outer end of the spring B is angled and provided with means for attaching it to the frame of the carriage. A rubber buffer or pad 0 is adjustably mounted on said spring B near the pintle b.
The jumper-spring B is preferably slightly curved and is provided upon its outer end with apintleb, by means of which it maybe detachably secured to the hinge a. I
When the device isto be used as. a simple or ordinary spring, as shown in Fig. 2, the pintle b of the spring B is inserted in the socket a of the hinge a and the j umper-spring B folded down upon the top of the spring B. When it is desired to convert the ordinary spring action into the jumper action, the pintle b of the spring B is withdrawn from the hinge a, and the jumper-spring B is turned upwardly over the spring B and the pintle I) inserted in the socket'a or a of the hinge a, as shown in Fig. 1, according to the weight carried, the socket a being employed for the lighter weight.
The rubber buffer C may be adjusted to any suitable point near the hinge connection between B and B where it will best subserve its intended purpose.
It has been found by actual experiment that with a spring constructed as above described there is in addition to the ordinary jumping motion a gentle reciprocating. motion of the carriage back and forth. Thus not only is the pleasure to the occupant of the carriage greatly increased, but an additional means of healthful exercise imparted.
At a suitable point on the spring 13 may be arranged a screw D, by means of which the tension of the spring B may be adjusted.
While I have herein shown a preferred form of carrying my invention into effect, yet I do not desire to limit myself to such preferred details of construction, but claim the right to use any and all modifications thereof which will serve to carry into effect the objects to be attained by this invention in so far as such modifications and changes may fall within the spirit and scope of my said invention.
I claim-- 1. A convertible spring and baby-jumper, comprising two springs hinged together, and
means for attaching an end of either spring to its operative position, substantially as de-' scribed.
2. A convertible spring and baby-jumper, comprising two springs hinged together, and means for detachably securing an end of either spring to its operative position, substantially as described.
3. A convertible spring and baby-jumper, comprising an inner and an outer spring hinged together, and means for attaching an end of either spring to its operative position, the outer spring being adapted to be swung back over the inner spring, substantially as described.
4. A convertible spring and baby-jumper, comprising an inner and an outer spring, a hinged connection between said springs, means for attaching the outer end of either spring to its operative position, the outer spring being adapted to be swung back over the inner spring and a spring-buffer intertachably securing the outer end of the inner spring and the outer end of the outer spring to either section of the said duplex hinge, and a spring-bufier interposed between the inner and the outer springs, substantially as described.
In Witness whereof I have hereunto set my hand in the presence of two witnesses.
GEORGE A. SMITH.
