EXTENSIBLE TELESCOPIG LEG.
SPECFIGATION forming part of Letters Patent No. 719,146, dated January 27, 1903. Application filed August 11, 1902. Serial No. 119,257. (No model.)
1'0 @Z whom if; may concern:
Be it known that we, WILLIAM A. SCHO- FIELD and LAURA D. ScnorrELD, citizens of the United States, and residents of Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Extensible Telescopic Legs, of which the following is a specification.
rl`his invention relates to an improvement in invalids beds', operating-tables, and the like, and has for its object a means for raising and lowering the saine.
The object consists, further, in providing each leg of the bed or table with a rod or tube which telescopes therewith.
The object consists, further, in an extensible leg the inserted portion of which carries a series of apertures. A collar is mounted on the extensible portion, which carries a spring having a pin secured thereto, the pin engaging with the apertures inthe extensible portion.
There are other features. The construction and arrangement of the several parts will be hereinafter more particularly described and then pointed out in the claim.
Referring to the accompanying drawings, which are made a part hereof, and on which similar numerals of reference indicate simil lar parts, Figure 1 is a fragmentary detail of the lower end of one of our extensible legs, showing the various parts of the invention in operating position. Fig. 2 is a partial section of the leg and a partial section of the extensible tube or rod. Fig. 3 is a side elevation of the collar by which the extensible portions of the leg are secured after being adjusted. Fig. 4f is a plan view of the construction shown in Fig. Fig. 5 is a horizontal cross-section of the collar on the dotted line 5 5 in Fig. 3. Fig. 6 is a partial section of the bed-leg. In this instance the bed-leg proper is inserted into the extensible part.
In the drawings, 1 is the leg of the bed, which is formed of a hollow tube.
2 is the extensible portion, which is formed of a tube or rod. 'Ihe portion 2 provides a Ineans for lengthening the leg and carries an ordinary caster, on which the bed or table rolls. Mounted on the extensible portion 2 is a collar 3. rlhe collar 3 is provided with an upward-extending annular flange 4,which runs to a feather-edge at the top. 'The outer side of the liange 4 is cut on an inclination, as shown in Fig. 3. The lower end of the portion l of the leg is slightly reained out to correspond with and to receive the flange 4. Thisconstruction allows the part 1 of the leg to readily adjust and seat itself on the collar 3. The collar 3 is provided with an annular groove 5. A spring 6 surrounds the greater portion of the collar 3 and lies within the groove 5. The ends of the spring 6 are coiled to form the shoulders 7. Thecollar 3 is provided on the opposite sides with the integral bars 8, which extend across the groove 5 in a transverse manner. In placing the spring 6 into position, the ends thereof are passed under the bars 8, thence are turned into the shoulders 7, the object for which will be hereinafter described. The spring 6 is provided with a pin 9 and a knob lO. The pin 9 extends through the wall of the collar 3 and projects into the core thereof. The knob 10 provides a grasp for drawing the spring 6 f0r ward until the piu 9 thereon is withdrawn from the aperture in the portion 2. The shoulders 7 on the spring 6 limit the forward movement of said spring by engaging with the bars 8, the foremost position of the spring being shown by the dotted lines in Fig. 5. It will be readily seen that when we desire to raise or lower the bed or table the spring 6 is drawn forward by catching hold of the knob 10 until the pin 9 is withdrawn from one of the apertures in the extensible portion of the leg, when the said part may be moved into the desired direction. Vhen the pin 9 is withdrawn from the extensible portion 2, it rests on the periphery (the part 2) until it registers with the succeeding aperture, into which it drops under the tension exerted by the springs own resiliency.
In Fig. 6 we have shown the extensible portion of the leg on the outside of the leg proper. In this construction the collar 3 surrounds the bed-leg proper. The collar 3 is provided at the lower end with an integral extended flange ll, which has an internal taper, the taper narrowing as it recedes from the end of the liange. clination of the collar receives the end of the IOO (See Fig. 6.) This internal inextensible part 2 and provides a means for the two parts to readily adjust themselves to each other. The collar 3 is provided with the set-screw l2, which passes through the flange 1l and bears against the surface of the extensible portion 2. This secures the two parts, and whereby the two may be simultaneously moved on the part l.
HavingF thus fully described our said invention, what We desire to secure by Letters Patent is- An extensible bed or table leg composed of hollow tubes telesooped together, apertures in the lower extensible portion, a collar having an annular groove mounted on the extensible section of the leg, a spring lying in said groove and having its ends coiled and formed in shoulders, bars integral with the collar which overlie the spring and engage with the shoulders on said spring, a pin secured to the spring, an aperture in the wall of the collar which forms a passage-way and guide for directingr the pin into the central core of the collar, a flange integral with the collar and having its outer side formed on an incline, the said flange adapted to enter the core of the leg, substantially as shown and for the purposes set forth. l
In witness whereof we have hereunto set oui` hands and seals, at Indianapolis, Indiana, 3o this 8th day of August, A. D. 1902.
