LANTERN-FRAME.

Specification of Letters Patent.

Patented Oct. 31, 1911.

Application filed November 6, 1907. Serial No. 400,911.

useful Improvements in Lantern-Frames, of a which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to lanterns of that style having the frame comprising a series of upright wire stays or guards fastened at their lower portions to a cylindrical tin body which receives the oil-pot, the upper ends and intermediate portions of said stays being secured to a plurality of horizontally disposed guard-rings composed of wire.

The main object of the present invention is to provide a more rigid and secure means of attachment for the upright stays to the cylindrical body, wherein the use of solder and the provision of apertures in the body may be dispensed with.

Another object of the invention is to provide an attachment which shall permit of convenient and easy assemblage of the parts in setting up the frame in the process of construction, whereby the various devices commonly employed for sustaining the stays in chlne or tool before it 1s applled to the body proper position during the operation of fastening the guard-rings may be dispensed with, thus resulting in a great saving of time and expense in the manufacture of the lantern-frame.

To that end the invention resides in the novel construction of the lantern-frame hereinafter described and claimed.

In the accompanying drawings Figure 1 is a side elevation of a lantern-frame of a well known style embodying my invention; Fig. 2 is an enlarged transverse section on the line Xf; Fig. 3 is an enlarged vertical section of a portion of the cylindrical body showing more clearly the attachment of the upright stays; Fig. 4 is an enlarged View of the lower portion of a detached stay; Fig. 5 is a side elevation of a lantern-frame of another well known style and showing a modification of the invention; and Fig. 6 is an enlarged detail vertical section of a portion of the latter frame.

Referring to Figs. 1, 2, 3 and 4 of the drawings, 1- denotes a plain cylindrical body which is composed of tin and is designed to receive the oil-cup in the well known manner. This body has applied to it the circular tin base 2' which, in some instances is permanently attached thereto and in other cases it is detachable. The said cylindrical body is imperforate, with excepticn of the provision of the usual air-draft holes.

To the exterior of the cylindrical body 1 is applied a continuous circumferential metalband 3. This band is permanently secured to the body in any suitable manner. However, to obviate the expense of soldering or riveting the parts, I provide the parts-with interlocking means consisting preferably of small coinciding engaging outward bulges -t-4-55 formed on the body and band respectively as more clearly illustrated in Fig. 2. These bulges are obviously produced by subjecting the body and applied band to the action of a suitable die-press or by the use of properly shaped tools. It will be apparent that by the provision of such bulges, the said band is rigidly sustained in its position.

Between the body 1 and band 3- are provided a series of vertical sockets -6 disposed intermediate the bulges and equidistantly apart around the body. These sockets are produced preferably by subjecting the band to the action of a suitable maso as to form the band at regular intervals with outward-deflections constituting channels which are concavo-convex in crosssection and extend the entire width of the band as clearly shown in Fig. 2.

77 denote the upright wire stays or guards which are bowed outwardly the greater portion of their lengths as usual and have their lower portions formed with Vertical shanks 8 which are flattened to form the same segment in cross-section to correspond with the sockets into which said shanks are inserted and at the same time to provide the shanks with rear faces which conform to the exterior surface of the cylindrical body 1. The junctions of the shank and bow-portions of the stays form shoulders bearing upon the upper edge of the band as indicated at 9-, and the lower ends of said shanks are formed with heads 1010 engaging the lower edge of the band, whereby the said stays are securely locked in the sockets. At the ends of the sockets the edges of the band are flared slightly as indicated at 11 to conform to the shoulders and heads.

7 -7- denote the usual horizontally disposed guard-rings to which the upper ends and bowed portions of the stays are secured.

Referring to the style of lantern-frame shown in Fig. 5 of the drawings, the upright stays -77 are secured to the cylindrical body 1 in substantially the same man ner as before described. In this instance however, the heads 1010- are dispensed with and the shanks are formed with o twardly-bowed downward extensions l212- which have their lower ends lapped around and soldered to a heavy horizontally disposed ring 13 constituting the base of the lantern-frame.

The junctions of the shanks and extensions form shoulders indicated at -14l1 l-, which shoulders bear against the lower edge of the band 3 in the same manner that the shoulders 9 9- bear upon the upper edge of the band as clearly shown in Fig. 6.

In the construction of either style of lantern-frame it will be noted that a large amount of soldering is eliminated, thus cheapening the expense of manufacture, and at the same time obviating the liability of depositing a sufficient quantity of solder into the tin-bath to discolor the frame in the operation of tinning the frame.

What I claim as my invention is:

1. In a lantern frame, the combination of a cylindrical body having a plain outer surface, and a continuous ribbon-like band encircling said body and permanently secured thereto by means of coinciding bulges, said band having a number of outwardly projecting ribs forming with the plain outer surface of the body straight vertical sockets, and a series of wireguards having straight portions intermediate their ends adapted to fit in said sockets, the straight portions of said wireguards contacting throughout their entire length with the plain outer surface of the body, and having shoulders for interlocking with the top and bottom ends of said ribs for preventing vertical movement in said sockets.

2. In a lanternframe, the combination with a cylindrical body, of a series of wire stays or guards formed with flattened vertical portions abutting against the exterior of the body and having said flattened por tions provided with faces conforming to the surface of the body, and a metal band extending around the exterior of the body and interlocked therewith by coinciding bulges formed on the parts, said band formed with outward deflections intermediate the bulges to conform to and embrace the abutting portions of the stays to lock the latter against turning, said stays being provided at the ends of the flattened portions with shoulders engaging the edges of the band to hold the stays against vertical movement as set forth.

3. In a lantern-frame, the combination with a cylindrical body, of a band extend ing around the body, the parts being united by interlocking bulges formed thereon, said band being provided with a series of vertical channels intermediate the bulges to form sockets between the parts, and a series of wire stays or guards formed with vertical shanks inserted into said sockets and provided with abutting-faces conforming to the surface of the body, said shanks provided at their ends with shoulders engaging the edges of the band as set forth.

4. In a lantern frame, the combination with a cylindrical body, of a plurality of wire-guards regularly spaced and having flattened portions which rest against the outer surface of the body, the said guards above and below the flattened portions curved outwardly to form shoulders, a con tinuous ribbon-like band surrounding the body and fitting the same snugly, said band having concavo-convex ribs corresponding in number and spacing to the said guards, for receiving and clamping said flattened portions of the guards tightly against the outer surface of the body, the opposite ends of said ribs flared outwardly to receive said shoulders for locking the guards against vertical movement, and coinciding bulges formed in the band and in the body for preventing the circumferential movement of said band.
