rm ne son RAILING AND THE LIKE,

Application filed May 31,

, To all whom it may concern Be it knownthat 1, ANDREW FALK, a citizen of the former Empire of Austria-Hungary,residing at Pittsburgh, in the county ofillleghei-iy and State of Pennsylvania, have invented a new and useful Improvement in Fittings for Railings and the like, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a side elevation showing a stairway railing embodying my invention and illustrative thereof. a I

Figure 2 is a vertical section of one of the intermediate cross fittings; II I Figure 3 is a section on the line V-'V of Figure 2; I I

Figure 4' is a vertical section of the/corner fitting or L; 1

Figures 5 and 6' are sections on planes at right angles to each otherof one of the T fittings; I V I I Figure '7 is a section similar toFigure 2, but illustrating a modification;

Figure 8 is an elevation and Figure 9 is a sectional view illustrating a modification of one of the intermediate'or cross fittings. I

'My invention has relation to fittings for use in the construction of pipe railings, such as stairway railings; and is designed to pro vide a set of fittings by means'of which-a pipe stairway can be constructed with its rails extending at any desired angle to its posts; T

The nature of my invention will .be best understood by reference tothe accompanying drawings, in which I have illustrated I the preferred form of the same, together with modifications of'some of the parts, it beingpremised, however, that the invention is susceptible of further modifications within the scope of the appended claims. I

Referring to the accompanying drawings, the numeral 2 designates a stairway having a railing embodying my invention. This railing is constructed of sections of pipe which constitute the rail members 3, and posts 1, of the railing, and which are connected by my improved fittings. I

The fittings for connecting the rails and post are in the form of Ls, Ts, and crosses,

provided with fixed sockets to receive the posts and with adjustable sockets to receive the rails. One of the crosses is shown in de- Sp'cification of Letters Patent.

tail in Figures 2 and 3. consists of a I:

hollow approximately spherical body 11, formed with oppositely projecting internally threaded fixed sockets 12, and with opposite slots13,'to receive the through bolt 14,;by which the adjustable sockets 15 are attached; These adjustable sockets have concave inner ends 16, which adapt them- .selves to the surface of the body 11, and it will be readily seen that by, loosening the nuts of the bolt 14, said sockets may be adjusted to any desired angle within the limits fthfe construction as indicated by the dotted lines in Figure 2. I

Figure a illustrates one of the Us consisting of a hollow approximately spherical body 11 having the fixed socket 17 and the adjustablesocket 18, secured by the short T-headed bolt 19, working through the slot 20 in thebody 11?.

Figures 5, and 6 illustrate one of the Ts. This consists of a body 21, with opposite fixed; sockets 22, and similar to the part 11 shown in Figure 3, The body, however, has but asingle slot 23, to which an adjustable socket 245 is connected by the bolt 25,

The manner in which several fittings are used in making a railing or similar structure will be clearly apparent by Figure 1. 1 The adjustable sockets can be quickly set and securedat the desired angles. i

In Figure 7 I have illustrated a modificationfiof one of the cross fittings in which the body portion 26 is similar to that shown in Figure 2, except that instead of the slots, it is adaptedto be tapped at any desired points between the fixed sockets for the attachment of oblique sockets 27 at the desired angles. WVhile this form of this fitting is less convenient than that shown in Figure 2, it may, nevertheless be used to advantage.

The sockets are tapered downward toward the body member 11. This permits the socket members to be brought closely together with a smaller angle between them than would be the case if they were untapered. As shown in Figures 2, 1-, 5, and 7, the adjacent sockets may be swung so that the angle between them is only about 15. This provides an adjustment whereby the angles between posts and rails may be varied ,from 90 to 415, thus permitting the fittings to be used onsteep Stairways.

WV hen it is desired to turn a corner with the railing, this'can be readily done by providing cross fittings having threaded aperpie set of fittings by means of which a pipe railing or similar structure can be cheaply and quickly made at the desired angle.

I claim:

1. An adjustable fitting device for inclined railings and the like, comprising a hollow body portion having a socket member integral therewith and having a slot for the attachment of an adjustable socket member, an-

adjustable socket member, and a T-shaped bolt extending from the adjustable socket member through. the slot and having its head received in the hollow body portion,,the head of the bolt being oblong and longer than the width of the slot, and the inside of the body portion at the sides of'the slot being formed to engage the ends of the bolt head and prevent it being turned, substantially as described.

2. An adjustable fitting device for inclined railings and the like, comprising a flattened cylindrical body portion provided with a fixed socket member projecting from its cylindrieal surface and having on its cyli n drical surface a slot for the attachment of an adjustable socket member at different andrical body portion provided with two fixed socket members projecting from its cylindrical surface in opposite directions and lying in the same plane and tapered conically toward the body portion so that the are along the cylindrical surface of the body portion subtended by a socket member is not greater than about two-thirds the thickness of the outer end portion of the socket member, another and separate socket member having acylindrically concaved surface of contact with the cylindrically convex surface of the body portion between the fixed sockets and similarly tapered conically toward the body portion so that its arc of contact is notgreater than about two-thirds of the thickness ofits outer end portion, and bolting means for-removably securing said separate socket member to the body portion, the conical tapers of the fixed and separate socket members allowing the separate socket member to be positioned in the same plane as said fixed sockets and close enough to a fixed socket member for use with railings for steep stairways and also giving a symmetrical appearance to the fitting when installed, substantially as described.

t. A fitting device for inclined railings and the like,rcomprising a flattened cylindrical body portion provided with two fixed socket members projecting from its cylindrical surface in opposite directions and tapered conically toward the body portion so that the are along the cylindrical surface of the body portion subtended by a socket member is not greater than about two-thirds the thickness of the outer end portion of the socket member, another and separate socket member having a cylindrically concaved surface of contact with the cylindrically convex surface of the body portion between the fixed sockets andsimilarly tapered conically toward the body portionso that its arc of contact, is not greater than about twothirds of the thickness of its outer end portion, and bolting means for removably securing said separate socket member to the body portion, the conical tapers of the fixed I and separate socket members allowing the separate socket member to be positioned in the same plane as the fixed sockets and close enough to a fixed socket member for use with railings for steep Stairways and also giving a symmetrical appearance to the fitting when installed, saidbody portion having fiat ends which permit the attachment, if desired, of

another socket member extending at right angles to the other socket members, substantially as described. 1 y

In testimony whereof, I have hereuntoset my hand.
