Description
FRANK G. JOHNSON AND SAMUEL I. THURSBY, OF BROOKLYN, N. Y.
iMPROVEMENT IN HYDRAULIC ELEVATORS.
Specification forming part of Letters Patent No. 14S, E23, dated March 3, 1874; application filed April 3, 1873.
To all whom t may concern:
Be it known that we, FRANK G. J onNsoN and SAMUEL I. THURsBY, both of the city of Brooklyn, in the county of Kings and State of New York, have invented certain Improvements in Hydraulic Elevators, of which the following is a specication: l
Our improvement pertains to elevators for buildings, Sac., in which a series` of telescopic tubes are extended, to raise a platformwhich they support, lthrough the agency of a Huid forced into them from below, as in the patent of E. F. Hope, No. 81,276, dated August 18, 1868, and consistsviiprbviding against the entire displacement of one tube from another in case of accident to any of the collars or stops upon the inner ends ofthe movable tubes, by means of flanges or guides secured to the top of each tube, (excepting that directly supporting the platform,) so that, should the end of one tube, from any cause, escape beyond the packing-joint between it and the one in which it slides, it will be still held in line, against lateral displacement, by the guideiiange upon the tube in which it slides, said iiange being made so as to allow the escape ot' the liquid through it from the interior of the tubing, under the circumstances stated, the effect of which is to cause the tubes to gradually descend into each other, a-nd thus prevent further damage.
In the accompanying drawings, Figure 1 is a side elevation, illustrating the arrangement of the apparatus 3 Fig. 2, a horizontal section in plane of line Fig. l; and Fig. 3, a vertical section, showing the arrangement of the guide-flange, &c.
The number of telescopic tubes, A A, employed is regulated according to the height to which the platform is to be elevated. rlhose tubes situated between the platform B and the lower stationary tubeA, (into which the liquid first enters,) are guided and centralized by the vertical ways O O, through the medium of the horizontal cross-heads a a, which are rigidly aixed to the upper ends of said tubes A. The
ends of the cross-heads a are bifurcated, so as to clasp the guideways O O, as shown in Fig. 2, or otherwise formed to suitably bear against said ways, according to the construction ofthe latter. Guide-flanges D are aflxed to the upper ends of each of the tubes A A, excepting that which directly supports the platform, to act as guides to the ends of the tubes, which they encircle, should the latter rise, from any cause, above the paekingjoint al between thetubes. These flanges or collarsD are hollow, and are perforated or otherwise formed to allow the escape of liquid from them, and they extend up and encircle the tube next above a sufficient distance to enable them to retain the end of said tube against lateral displacement, if, by reason of the accidental detachment of its ange or stop a2, it should escape beyond thepacking-joint, as above mentioned, in which case the liquid would also rise into the collar D, and from thence escape and allow the end of the tube to descend again into the tube next below.
The use of the cross-head a insures the alignment of the tube during extension, and counteraets any tendency to lateral displacement, and consequent friction and undue strain upon the packing box and joint employed to render the tubing water-tight, and at the same time simplifies the construction of the apparatus.
By the use of the guide-ilanges D, preserving the alignment of the tubing in case of accident, as stated, and providing for the gradual lowering or closing of the tubing under such circumstances by the escape of liquid from the interior of the tubing, the apparatus -is rendered more safe and reliable.
Vhat we claim is- The guide-ilange D, arranged and constructed substantially as described, and for the purpose specified.
