To all whom it may concern:

Be it known that we, FRANK A. CASTEEL and ROBERT M. MAYFIELD, citizens of the of whichthe following is a specification.

tit

The means usually employed for attach ing miners lamps to miners hats or caps ad-.

mit of the lamps having a play which is annoying and otherwise objectionable because of the jar occasioned by the swaying or lateral vibratory, movement of the lamp;

resulting from the natural movements of the miner when at work.

This invention provides securing means for the miners lamp which, while admitting of the lamp being placed in position upon the hat or cap or removed therefrom with the greatest facility bythe usual slip-joint,

will at the same tune prevent any play or movement of the lamp when attached to the hat or cap, thereby avoiding the jar, incon venience and other annoyance usually experienced by the ordinary joint which, permits of the lamp having a swaying movement and lateral play.

iflhe invention consists of the novel and pedtiliar joint between the lamp and the bracket attached to the hat or cap, such joint admitting of placing the lamp in position or removing it from the cap in the ordinary way but which joint will be free from any lateral play and hold the lamp rigid.

The'invention also consists of the unique form of bracket embodying a socket formed in such a manner as to coact with the lug of the lamp to preclude any possible swaying of the lamp when the latter is placed in position on the hat or cap.

The invention furthermore consists of the novel features, details of construction and combinations of parts which hereinafter will be more particularly set forth, illustrated and claimed.

In the drawings hereto attached: Figure 1 is a view in elevation, parts being broken away, of means for attaching a miners lamp to a miners hat or cap embodying the invention. Fig. 2 is a horizontal section of the lamp attaching means, the lamp being indicated in full lines. Fig. 3 is a perspective view of the bracket as seen from the rear.

'portion of the bracket as seen from the front. Fig. 5 is a perspective view of a portion of a minerslamp showing more clearly the lug attached thereto for cooperation with the socket of the bracket. Fig. 6 is a detail section of a modification.

, Corresponding and like parts are referred to in the following description and indicated. in all the views of the accompanying drawings by the same reference characters.

The bracket which is attached to the hat or cap comprises members 1, 2 and 3, corresponding respectively 'to the crown, body and Vizor, or brim of the hat. This bracket is preferably constructed of sheet material, such as metal, so as to be light and resilient.

Opposite edge portions of the component parts of the bracket are reinforced, as indicated at 3 such reinforcements consisting of edge portions of the blank from which the bracket is formed being folded upon themselves. In the preferable construction the crown member 1 of the bracket is in a slightly lower plane than the upper edge of the body member 2, thereby leaving a projecting portion 4. extending vertically above the forward portion of the part 1. The vertically extending portion 4 is formed by folding the blank upon itself and then bending the part 1 outwardly from the part 2 a short distance from the folded edge, as indicated most clearly in Fig. 3. A socket 5 is formed in the upper portion of thever tical or crown part 20f the bracket and is adapted to receive the lug carried by the lamp. The socket 5 is transversely elongated, as shown most clearly in Fig. 2, and is comparatively narrow between its front and rear walls. The length of the socket is such as to insure a firm. and substantial connection being obtained between the co operating parts, such as the socket and lug, comprising the joint. The body portion 2 of the bracket constitutes the front wall of the socket. The rear'wall of the socket is .the socket are resilient, hence are adapted to formed by means of a strip of sheet matelot yield to. admit of the lug being pressed into the socket so as to obtain a snug fit therein and prevent any possible play or movement. While it is contemplated to secure the strip Bto the bracket in any manner, yet it is preferred to attach the same by means of the folded edge portions 3*, thereby simplifying the const uction and avoiding the necessity for utilizing extraneous fastening means. A vertically extending slot 8 is formed in the front wall of the socket'and opens through the upper edge of the part 2', thereby adv mitting of the lamp being placed in position or removed from the socket by meansof a slip-joint. The slot 8 is'open at its upper end and the vertical walls defining uch slot are flared at their upper ends, as indicated at 9, thereby giving aflare to the entrance,

.end of the slot so as to direct the lug into the socket and slot when placingfthe lamp in position. I

The lug attached to the lamp comprises a web 10 and a plate 11. relative vertical arrangement and. is of a width corresponding to the width of the slot 8 so as to fit such slot snugly. One edge of the web 10 is joined to the rear wall of the lamp 152. The opposite vertical edge of the web 10 has the plate 11 joined thereto, such plate projecting equidistant from opposite sides of the web 10,, hence such web occupies a medial position. to enter the socket 5 and 'fit the same snugly. The plate 11 by reason of its function may be designated as the. socket-plate and its lower end projects below the web 10 and is made tapering, as indicated at 13, so as to readily enter the upper end of the socket 5.

The thickness of the socket-plate 11 corresponds to the-distance between the front and rearwalls of the socket 5 to insure a snug fit between such plate and the walls of the socket, thereby preventing any possible play .be pressed together so that when the lug is slipped into the socket the plate 11 will press such walls apart and as a result the inward tendency of the front and rear walls of the socket to come together will create sufficient friction ,on the socket-plate 11 to prevent any possible movement or displacement ofthe lamp.

' In the modification shown in Fig. 6 the crown portion 1 of the bracket is in the plane The web 10 has a.

The plate 11 is designed 5 is open throughout its length of the body portion, hence" the receiving end of the socket 5 is in the plane of the crown portion of the bracket. The vertically extend1ngportion4 is adapted to engage the lower end of the socket-plate 11 and thereby direct such plate to the socket when moving the lamp laterally along the upper part of the bracket, such tapered. end of the plate. 11 dropping into thesocket when registering therewith. It is to be understood that the invention may be applied to the various types of miners lamps and hats or caps, 1 hence when adapting the invention to a particular style of lamp or head covering, it is to be understood'that various changes in the form, proportion and minor details of con-L struction may be resorted to within the scope of the invention as claimed, without depart;2'

ingfrom theessential features thereof.

Having thus described the invention what 5 is claimed as new is I 1. Means-for attaching a miners lamp to a miners hat or cap, the same comprising a member having a transversely elongated socket formed between two walls which are resilient to yield, one of such Walls being formed with a relatively vertically extending slot which is open at its upper end, and a lug attached to the lamp and comprising a socket-plate and a web to enter and fit within the open-ended slot formed in the wall of the socket.

2. Means for attaching a miners lamp to a miners hat or cap, the same comprising a member having arelatively vertically extending socket which is transversely elongated and comparatively shallow between the opposing Walls, one of such walls havmg a relatively vertically extending slot which fis open at its upper end and made 105 flaring, and a lug attached to the lamp and, comprising a .socketsplate made taperingjrt' its lower end, and a centrally disposed Web connecting the socket-plate with the lamp i and adapted tosnugly fit within the openended slot of the socket.

3. Means for attaching a miners lamp to a miners hat or cap, the same comprising a bracket, a strip having end portions attached to the edge portions of bracket and an intermediate portion deflected to form a socket, the bracket Wall of the socket having an open-ended slot formed therein, and a lug attached to the lamp and comprising a socket-plate and a web. v

4. Means for attaching a miners lamp to a miners hat or'cap, the same comprising a bracket having opposing edge portions. folded, a strip placed against the bracket and having its end portions confined between folded edge portions of the bracket, said strip having its middle portion deflected to form a socket, the bracket wall of the socket having an open-ended slot formed therein, and a lug attached to the lamp and 130 'tions folded to form reinforcements. such blank being bent to form crown, body and vizor members, and a strip having its end portions secured to the body member of the bracket by means of the folded edge portions of the blank, such strip having its middle portion deflected to form a socket,

thefront wall of such socket having a relatively vertically extending slot.

6. The herein described bracket to be attached to a miners hat or cap, the same being formed of a sheet metal blank having opposed edge portions folded, and such blank being bent to form crown, body and vizor members, the crown-member being slightly lower than the ,upper edge of the body member leaving a Vertically extending portion which is formed by a fold of the,

blank, and a strip placed against the rear side of the body member and secured at its ends thereto by means of the folded edge portions of the blank, such strip having its middle portion deflected to form a socket, and such socket having a relatively vertically extending slot formed in its front wall, the upper end of such slot being open and flared.
