CHARLES B. BARTLEY, OF PITTSBURGH, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TO GEORGE F. RYLANDS, OF CI-IARLEROI, PENNSYLVANIA.

LAMP-BRACKET.

To all whom it may concern:

Be it known that I, CHARLES E. BARTLEY, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Lamp- Brackets, of which the following is a specification.

My invention consists of an improvement in lamp-supporting brackets for miners lamps, and particularly a storage battery lamp.

The object of the invention is'to securely support the lamp upon the cap of the wearer and to provide a supporting holder adapted to receive and hold the lamp, to permit of adjustment of it to various angles for directing the ray of light, the construc tion by which the lamp is completely insulated, and various other features of construction as shall be more fully hereinafter described.

In the drawings: Figure l is a perspective view of the apparatus in position and provided with a battery lamp. Fig. 2 is a vertical sectional view through the central portion of the bracket, indicated by the line II. II. of Fig. 3. Fig. 3 is a plan View of the device. Fig. 4 is a view in front elevation.

Ordinarily the usual wick lamp commonly used by miners is merely supported on a forwardly projecting bracket of sheet metal by means of a retaining hook.

In carrying out my invention, I secure upon the cap 2 a bracket 3 extending outwardly from the front of the cap, as shown in Fig. 2, and secured thereon by securing rivets 4, 4, at the top and lower portion respectively and extensions 5 and 13, to the cap and its vizor, in the same manner as is customary with brackets for wick lamps. My improved bracket 3, however, is preferably made entirely of insulating material, as stiff fiber board. The object of such construction is to avoid the possibility of short circuiting or of injury to the miner by making contact by any of the metallic portions of the bracket or lamp with current conducting wires in the roof of the mine, etc.

Fixedly secured to the lower forwardly eX- tending base 5 of the bracket 3, by a lower tongue 6 and rivets 7, is the battery holder Specification of Letters Patent.

Serial No. 651,425.

8. Said holder is of box-like form having parallel sides terminating at the front in inwardly directed retaining flanges 9, a back 10, and a lower retaining or supporting lip or flange 11, preferably of thin sheet metal. The back 10 is secured to the lower tongue extension 6 by rivets or in any other suitable manner, and is also provided at its upper back portion with a rearwardly extending securing lip 01' tongue 12. Said tongue is provided with a longitudinal slot 13 by which the bracket is adjustably secured to the top horizontal portion of the bracket 3, by means of a bolt 14, and terminal thumb nut 15. The connecting rivets are provided with insulating washers and bushed with insulating material wherever used, effectually preventing any possibility of passage of current due to contact with the rivets. The lower supporting tongue 6 is rounded, as at 16, and is sufliciently flexible so that the upper portion of the bracket may be adjusted forwardly or backwardly at any desired angle and there secured by the bolt and nut 14;, 15. As stated, the bracket 3 being of insulating material, there is no metallic connection between the lamp supporting case and the bracket 3 at any point so that transmission of any current is thus prevented. The inner front portion of the back 10 of the lamp holder 8 is provided with a cleat 17 extending outwardly from the main back and partly severed therefrom by slots' 18, by which means lamp A is positively retained in position by means of a resilient tongue or clip 19 (indicated in dotted lines in Fig. 2).

The lamp A, which is of the storage battery type and of any suitable construction, is of convenient size and shape to be inserted within the holder 8, resting upon the lip 11, and is retained by the front flanges 9 and the clip 19 inserted behind cleat 17, as will be readily understood. By this construction the lamp is firmly secured in position and may be readily carried upon the cap of the wearer. The tilting adjustment permits of any desired range of the ray of light to suit the position or height of the user and to adapt the device to the work in view.

The entire apparatus is comparatively simple and cheap in construction, light and durable, and not liable to get out of order and in practice has given very satisfactory results.

Having described my invention, What I claim is:

1. In a lamp holder, the combination with a cap, of an insulating bracket secured to the cap, and a lamp supporting holder and easing mounted on the bracket and electrically insulated from the cap.

2. In a lamp holder, the combination with a cap, of an insulating bracket secured to the cap, and a lamp supporting holder and easing mounted on the bracket and adjustably secured thereto, and electrically insu lated from thecap by said bracket.

8. As an article of manufacture, a bracket for a storage battery lamp comprising a base portion of insulating material shaped to conform and adapted to be secured to a cap, and a lamp supporting holder adapted to carry a storage battery lamp mounted on said base portion and insulated thereby, substantially as set forth.

4. As an article of manufacture, a bracket for a storage battery lamp comprising a base portion of insulating material shaped to conform and adapted to be secured to a cap, and a lamp supporting holder adapted to carry a storage battery lamp mounted on said base portion and insulated thereby, and having means for adjustably securing it thereto, substantially as set forth.

5. A lamp holder for storage battery lamps consisting of a bracket fixedly secured to a cap, and a lamp holder having a receiving case, a lower flexible securing tongue attached to the base of said bracket and an upper rearwardly extending tongue adjust-ably secured to the upper portion of said bracket, substantially as set forth.

6. Alamp holder for storage battery lamps consisting of a bracket fixedly secured to a cap, and a lamp holder having a receiving case, a lower flexible securing tongue attached to the base of said bracket, an upper rearwardly extending tongue having a longitudinal slot, and a securing device for fixedly attaching it to the upper portion of said bracket, substantially as set forth.

7. In a lamp holder, the combination with a bracket of insulating material adapted to be mounted on a cap, of a receiving casing for the lamp having a retaining device, a lower securing tongue attached to the base of the bracket, and an upper rearwardly extending slotted tongue adjustably secured to the upper portion of the bracket, substantially as set forth.

8. In a lamp holder, the combination with a bracket of insulating material adapted to be mounted on a cap, of a receiving casing for the lamp having a retaining device, a retaining cleat in the inner back portion of the holder, a lower securing tongue attached to the base of the bracket, and an upper rearwardly extending slotted tongue adjustably secured to the upper portion of the bracket, substantially as set forth.

9. The combination with a supporting bracket having a lower forwardly projecting portion and an upper rearwardly projecting portion for attachment to a cap, of a casing of sheet metal having a downwardly extending flexible tongue secured to said bracket, a forwardly and rearwardly extending slotted tongue, a securing bolt, and a casing carried by said tongues having a back provided with a securing cleat, sides having front terminal flanges, and a lower supporting lip, substantially as set forth.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.

CHARLES B. BARTLEY.
