STANCHION FOR HAND-RAILS.

To all whom it may concern:

Be it known that I, CHARLES B. OCon- NOR, a citizen of the United States, residing at Portsmouth, in the county of Norfolk and State of Virginia, have invented certain new and useful Improvements in Stanchions for Hand-Rails,of which the following is a specification.

This invention relates to hand rail stanchions having for its primary object to provide a novel and useful means for supporting the rail, holding the same in a rigid position and at the same time allowing for the almost instantaneous removal of the rail from the stanchion when it is so desired.

Another object of the invention resides in the provision of a device of this character which is especially adapted for use in connection with locomotive boilers.

A further object which this invention contemplates is to provide a stanchion including a pair of jaws, the one of which is connected to the opposite jaw through the medium of a screw, the screw serving the dual purpose of holding the rail between the jaws in conjunction with holding the jaws snugly in engagement as above pointed out; the adj ustable jaw is secured to the stationary jaw diagonally so that the pull on the rail will be directly on the screw shank and not transversely of the jaw, very often causing the screw to be broken or the rail distorted, when undue pressure is exerted upon the rail.

Other objects as well as the nature, characteristic features and scope of my invention will be more readily understood from the following description taken in connection with the accompanying drawings and pointed out in the claims forming a part of this specification.

Referring to the drawing, Figure 1 is a side elevation of the device constructed in accordance with my invention illustrating the application thereof. Fig. 2 is a vertical sectional view of the stanchion, showing the rail in connection therewith; and, Fig. 3 is a side elevation of the same, the rail being shown in fragmentary sections therein.

In the drawings wherein is illustrated the preferred embodiment of this invention, in order to properly illustrate the application of the same a boiler shell 5 is shown which is provided with an opening through which Specification of Letters Patent.

is passed a bolt 6, the bolt 6 being provided with external screw threads for engagement pith the internal thread 7 of the stanchion My improved stanchion comprises a leg 8 as above stated, the lower end 9 of which is flared outwardly so as to facilitate the setting of the same on the outer periphery of the boiler, while the opposite end thereof is slightly tapered and terminates in an integrally formed jaw 10, the jaw being preferably of a semicircular configuration and formed at an inclination thereon for a purpose which will be more fully hereinafter set forth. The inner face of the jaw 10 is likewise semicircular as indicated at 11, and has a portion 12 thereof cut out adapted for engagement with the enlarged portion 13 of the adjustable jaw 14. The adjustable jaw 11 is likewise of a semicircular contour and has the inner face thereof semicircular, registering with the inner face of the stationary jaw 10 so as to form a circular opening for engagement with the outer periphery of the rail 15. The adjustable jaw 14 has a cut out portion 16 formed therein which is adapted for engagement with the head 17 of the screw 18, the screw threaded portion 19 of the shank of the screw adapted for engagement with the rail 15 and the stationary jaw 10. Upon reference to Fig. 2 of the drawings it is seen that the screw 18 serves a dual purpose, namely; that of holding the adjustable jaw 14 snugly in engagement with the stationary jaw 10, likewise retaining the rail 15 within the jaws and preventing the movement of the same.

In operation the bolt is passed through the boiler shell 5 and threaded into engagement with the threaded bore of the leg 8. Assuming that the adjustable jaw 14 and the rail 15 are removed from engagement with the stationary jaw 10, the rail 15 is then placed into engagement with the semicircular inner face 11 thereof and the adjustable jaw 14 placed thereover and into engagement with the stationary jaw, the extended portions 13 of the adjustable jaw engaging with the cut out portions 12 of the stationary jaw so as to positively prevent the movement of one jaw with respect to the other. The screw 18 adjustable jaw 14, said aperture communicating with the cut out portion 16 thereof,

is then inserted through an aperture in the a the bolt,

the pipe after a certain length of time will pull lengthwise on the bolt as indicated by the arrow in Fig. 1, in which instance it is seen that the stress instead the screw 18, causing the threads 19 to bind with the threads 8.

It will be understood scription and accompanying minor changes in details of construction,

proportion and arrangement of the parts may be made within the scope of the appended claims and without sacrificing any of the advantages of my invention.

1 claim 1. A stanchion for hand-rails including a leghaving one of its ends formed to provide an inner jaw for engagement with the handrail, an, outer aw engaged with the inner jaw, the proximate edges of said jaws being correspondingly cut out to interengage for preventing displacement of said outer jaw longitudinally of the hand-rail, and means detachably engaged through the jaws and the hand-rail to prevent accidental displacement of the hand-rail from the stanchion.

2. A stanchion for hand-rails including a supporting leg having one of its ends formed to provide an inner jaw which is set at an inclination, an outer jaw having the marginal edge thereof interengaged with the marginal edges of the inner jaw, and a screw mounted transversely through the median of the outer jaw and through the hand-rail into engagement with a threaded recess in said inner jaw, whereby the screw is disposed diagonally of said leg to throw the stress intermediate the terminal ends thereof, very often causing the tearing of,

of being on the. rail 15 which is usually tubular, will fall on thereof that the above de-v drawings com- 1 prehend only the general and preferred embodiment of my invention and that various of the pull of the hand-rail on the shank of the screw.

3. A stanchion for hand rails in combina tion with a boiler shell. and a tubular hand rail, a bolt having engagement through said shell, a stanchion supporting leg provided with a threaded recess in the one end thereof for engagement with said bolt, a jaw formed on the opposite end of said leg, being diagonally thereon, the inner face of said jaw bein semicircular and provided with a cut out portion communicating with said semicircular portion, an adjustable jaw adapted for engagement wlth said stationary jaw, an

enlargement formed on said adjustable jaw for engagement with the cutout portion of said stationary aw and provided with a semicircular inner face for registering. engagement with the inner face of said stationary jaw, and the screw engaged diagonally through said j aws and said tubular hand rail, for the purpose set forth.

1. A, stanchion for hand rails including a leg, the one end of which is flared for en gagement with the outer periphery of a flared boiler, a semicircular jaw formed on the opposite end of said leg, the inner face of said jaw being provided with a semicircular recess and a cut out portion cemmunieating with said recess, an adjustable jaw, an enlargement formed on the inner face of said jaw for engagement with the cut out portion of said first mentioned jaw, said adjustable jaw being provided with a semicircular recess registering with the semicircular recess of the first mentioned jaw, said adjustable jaw being provided with a cut out portion in the outer periphery thereof and approximately midway its ends, a screw en gaging diagonally through said adjustable jaw, the head thereof having engagement in said recess and the opposite end provided with screw threads for adjustable engagement with said first named jaw.

In testimony whereof I aflix my signature in presence of two witnesses.
