To (/ZZ whom it may concern: t

Be it known that I GLOIOEB. BAKER, a states, residing at St. Louis, state of Missouri',,have invented certain new andusefulImprovements in Handrail-Columns, of which the "following is a 7 being had to the accompanying drawings,

forming a part hereof- Y The present invention is directed to improvements in hand rail columns or brackets, particularly as applied to locomotlves. As well understood in the art, a'locomotive boiler is usually covered with a lagg'ing of asbestos or mineral wool which is protected by an outer metal sheet or jacket usually:

made up of sections wrapped around the boiler. The studs to 'which'thehand rail columns are secured pass through the lagging and jacket, the outer ends of the studs being screw threaded to receive the threaded sockets of the columns, the :outer ends of the columns'terminating in loops or, eyes through which the handrail is passed. When it becomes necessary for any reason to remove one of the jacket sections, the hand rail must first be withdrawn from the eyes of the supporting columns to permit the unscrewinj of the columns from the studs, after which the jacket is'pulled out from the studs and removed. Such removal of the jacket. is necessitated for example in cases where, a leak in the boiler is to be stopped orother repairs made to the boiler shell. The object of my invention is to provide a hand rail column or bracket which does not require the removal of the hand rail when occasion arises to take down a section ofthe outer jacket. This of course is adecided advantage in thatitnot only saves time and labor butdispenses with the necessity of making the handrail in sections which withthe ordinaryicolumn must be done to facilitate withdrawal of the rail from the supportingloops or eyes of the columns. Under my invention the column is made in two sections which may be separated fromoneanother at any time, one of the sections (the one carrying the'loop) being slipped along the rail out of the way while the other section or that coupled .to the securing stud can be readily unscrewed from the stud without disturbing the rail.

The advantages of the invention will be more fully apparent from the following dethe same are assembled. threadedexten'sion 6 is ofiset from the loop v a connection with the ac companyingldrawings in which' F gure 1. represents aside elevation of a locomotive showing my invention applied thereto; Fig. 2 is anenlarged' cross-section through the boiler shell, the lagging, and outer jacket thereof, showing my improved tailed description in columninelevation, applied thereto; Fig.

3 is a detached elevational view of the improved colu nn; Fig. 4 is a lon itudinal middle section therethrough; and 1s a perspective of a column parted so as to permit the shifting of the outer section along the hand rail.

, Referring to the drawings, 1 represents the shell of the boiler, 2, the lagging, and 3 the outer jacket, the studs 4 leading from the shell or boiler wall through the lagging and jacket and terminating at their 'outer ends in athreaded portion to which the columns or brackets are secured as well understood in the art. I In the present embodiment of my'invention the hand rail column is composed of two sections ormembers, the inner or bot tom section comprising an intermediate cylindrical portion .5 terminating at one end in an expanded base 5, and at the opposite end in aslightly enlarged threadedportion 5f, the bottom of the memberbeing pro- .vided with the usual threaded socket a foreye 6 for thereception of the hand rail 7 as usual in the art, and an inner reduced threaded portion or extension 6" of the same cross-section as the threaded portion 5 of the first section, the ends of the portionslbeing brought into abutting relation when The reduced 6 by an inclined outwardly flaring shoulder 8, said shoulder receiving the correspondingly beveled end of a coupling sleeve 8 screwed over the'threaded " portions 5, 6, the length of the sleeve corresponding to the combined lengths of the threaded portions over which the same is passed. The length of the intermediate portion 5 of the innercolumn section is sufficient to allow the sleeve 8 to be wholly unscrewed. from the threaded portion 6 of the outersection so that when occasion requires, said outer secti on may be readily detached from the bottom Specification of Letters Patent. Patented July 6 192() section (Fig. 5; also dotted lines Fig. 4). In practice, when occasion arises to remove a section of the jacket 8, the operator simply unscrews the coupling sleeve 8 sufliciently to separate the two-sections of the column,

the outer section being then moved along the rail 7 out of the way of the bottom section to be removed (Fig. 5). With the outer column section out of the way, the bottom section of the column is then unscrewed from the stud f, permitting the jacket'to be passed off the stud and thereby removed from the boiler without disturbing the hand rail. In the same'manner the lagging may be passed sleeveS screwed home against thershoulder s, and this without the necessity of disturbing the hand rail. The column is therefore a time saver and reduces the cost of repairs. It is of course apparent that I may change the construction in minor details'without departing from the nature or spirit of the in- L vention. The advantage of the present construction lies in the fact that when the cou pli'ng'sleeve which spans. the joint formed by the abutting terminals between the column sections is moved past the point or un screwed sufficiently to release the outer section, the latter can be moved to one side or in a direction at right angles to the axis, of the column. 'The outer section beingthus moved to one side, allows the bottom section to be removed independently from the securing stud4 without disturbing the hand rail. i

Having described my invention what I claim is,

j 1. A hand rail column comprising an outer section to which the rail is applied, and an inner section to be attached toa fixed support, and separable from the first section, and means disposed about the peripheries of the sections for coupling the sections together.

2. A hand rail column comprising an outer section to which the rail is applied, an inner section, means on the bottom of said inner section for securing the same to a fixed support, and means engaging the peripheral walls of the sections for coupling the sections together. I

3. A hand rail column comprising an outer section to which the rail is applied, an inner section, means on said inner section for securing the same to a fixed support, and a movable member encompassing adjacent portions of the sections for coupling the sections. 1

4. A hand rail column comprising an outer section provided with a hand rail-receiving loop and a reduced threaded exten- V sion leading and offset therefrom, a bottom section terminating at one end in a threaded portion'of the same cross-sectional. diameter withthe reduced threaded extension of the outer section and adapted to be placed in abutting relation therewith, the bottom section having a slightly reduced portion leading from the inner end of the threaded portion thereof, a coupling sleeve passed over sections in abutting relation disposed about a common axis, a coupling sleeve spanning the joint between the sections and adapted to be moved past the joint aforesaidkto allow one of the sections to be moved in a direc-' tion at right angles to the axisaforesaid.

7. A hand rail column comprising a bottom section having at one end an expand,

ed base, a central reduced portion, and a slightly enlarged threaded portionat the op posit'e end, and anouter section composed of a handrail-receiving loop and of a reduced threaded extension leading and offset from 1 the looped portion by an inclined outwardly flaring shoulder, the threaded portions of the sections being of the same cross-sectional diameter and forming a butt joint with one another, a screw sleeve passed over the threaded portions and spanning the joint aforesaid for coupling the sections together, one end of the sleeve being beveled to engage the inclined shoulder aforesaid, the length oftheintermediate reduced portion of the bottom section being such as to allow the.

sleeve to be fully unscrewed from the threaded extension of the outer section, thereby permitting said section to bemoved to one sidealong the rail to permit removal of the bottom section. I r

In testimony whereof I afiix my signature, in presence of two witnesses.-
