Specification of Letters Patent.

Patented Nov. 18, 1919.

Application filed August 20, 1919. Serial No. 318,830.

To all whom it may concern Be it known that 1, WILLIAM F. Bossnn'r, a citizen of the United States, residing at Utica, in the county of Oneida and State of New York, have invented certain new and useful improvements in Apparatus for Adjusting Switch-Points; and I do hereby de clare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This inventionrelates to new and useful improvements inattachments to apparatus for operating switch points, and consists essentially in the provision of means espe cially adapted to the type of device covered by Letters Patent #1,136,767, granted to me upon April 20, 1915.

It has been found from practice that the steel end caps of the type referred to, and which are made of hard drawn steel and secured to the switch adjusters, frequently be come inefficient during severe cold weather, and the torches which are commonly used for thawing snow and ice about the adjuster takes the temper out of the end caps, and as a consequence they become loose and slide upon the rods and nuts, and do not afford the desired protection.

The present invention consists in the provision of an end cap of substantial weight and made preferably of malleable iron and which may be easily and quickly attached to the adjuster when in operation.

The invention comprises various other details of construction, combination and arrangement of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings which, with the numerals of reference marked thereon, form a part of this application, and in which:

Figure 1 is a central longitudinal sectional view through the casing in which the adjustable switch operating rods pass, the attachments being shown in section.

Fig. 2 is a sectional view on line 22 of Fig. 1.

Fig. 3 is a detail view in elevation of a modified form of the attachment comprising two complemental sections adapted to be connected by bolts.

Fig. 4: is a View in elevation showing a different modification of the attachment, in which a stud joint connection is provided between the parts, and

Fig. 5 is a still difierently modified form in which the parts have knuckle joint connection.

Reference now being had to the details of the drawings by numerals:

1 designates a casting having a flanged portion 2 apertured for the reception of the bolts 3 forming means whereby the switch point throwing bar 4 may be held to said casting. A casing 5 which is hollow is provided with a central contracted portion and each end of the casing flares, as shown, at 6 forming a cup shaped chamber, the inner surfaces of which are concaved as at 7 and form abutment surfaces. A rod 8 circumferentially threaded passes through the casthrowing apparatus (not shown) is adapted to be secured whereby a longitudinal movement may be imparted in one direction or the other to said rod. Cylindrical nuts 9 and 12 are mounted upon said rod and have their inner ends convexed adapted to conform to and bear against the concaved surfaces 7 in the chambered portions of the casing and the circumferences of the outer ends of said nuts are squared as at 10 affording means to be gripped by a wrench or other tool to facilitate turning the nut upon the rod. Jam nuts 11 are mounted upon the threaded rod and adapted to bear against the nuts 9 and 12 to hold the same from loosening.

Caps designated respectively by numerals 15 and 16, made preferably of malleable iron, are made up of two sections and connected together by means of a pivotal pin 18. Each of said sections has a lateral flange with a concaved groove upon its inner surface adapted to engage over a beading 19 upon the casing 7 and at points diametrically opposite the pivotal pin and each end of a cap section has a laterally extending lug 20 apertured for the reception of a bolt 21 adapted to hold the two sections in clamped relation with the casing, and upon said bolt a nut 22 is mounted and. preferably intermed ate the nut and the adjacent lug of a section 18 a nut locking member 23, the ends of whlch are adapted to bite into the adjacent faces of the nut and locking member to hold the nut from loosening.

A washer ii is placed intermediate the sections of the end of the casing to provide a close fit around the adjusting nuts and have the same inside diameter as the outside diameter of the adjusting nuts, the outside diameter ,of the washer being semewl at larger than the diameter of the chambers in the adjusting casing and thereby afiiording means for protecting the chamber against the accumulation of snow, ice and foreign matter, and at the same time providing a means whereby any binding of the switch adjusting rods, caused by the creeping of the rails, may be obviated, this being eltected by reason of the adjusting nuts being of considerably smaller diameter than the chamber of the adjuster.

In Fig. 3 of the drawings 1 have shown a modified form of my two-part cap, in which the sections 26 and 27 are of complement-a1 form and each provided with oppositely disposed lugs 28 in alinement with each other and provided with registering apertures for the reception of fastening bolts 29, instead of the use of a pivot, as shown in Fig. 2.

In Fig. 4 I have shown a modified form in which the section 30 is provided with a stud 31 upon a lateral. project-ion 32 at one end of said section and which is adapted to engage over an integral hook formed integral with the section 34:. and forming a hinged joint, while the opposite ends of said section are provided with lugs 35 and registering apertures for the reception of the bolt.

In Fig. 5 is illust 'ated a still dili'erently modified form of the invention, in which the section 36 is provided with an integral hook 37 adapted to interlock with a hook 38 upon the section 39 forming a knuckle joint, the opposite ends of the section being provided with the usual apcrtured lugs 40 for the reception of a bolt.

By the provision of a cap made up of sections as shown and described, and which is of substantial weight and made of malleable iron, same may be easily attached to the adjusters and provide a. strong and solid attachment to obviate the objections occasioned by caps which have heretofore been used with the form described in my former referred to patent, the sections being easily replaced when desired.

What I claim to be new is:

l. Attachments for casings for apparatus for adjustin switch points on railways, consisting or" curved sections for attachment about the casings, and means for holding the sections together about the casings,

Attachments for casings tor apparatus for adjusting switch points on railways, comprising curve-d sectional cans each having a concaved groove in its inner face, and means for fastening the sections together.

3. Attachments :lor casings for apparatus for adjusting switch points on railways, caps made up of two complemental sections, each having a lateral flange which s provided with a cylindrical groove upon its inner surface tapted to engage over the end of a. casing, and means for holding the sections together.

4t. Attachments "tor casings for apparatus for adjusting switch points on railways, caps made up of complemental sect-ions to engage'over the end of a casing, the corresponding ends of the sections being pivoted, and a bolt connecting the opposite ends at points diametrically opposite.

In testimony whereof I hereunto affix my signature.

'WILI 1AM if. BOSSERT.
