FREDERICK E. MCLAUGHLIN, OF EVERETT, WASHINGTON.

RAILWAY LAMP.

Application led March 29, 1926. Serial No. 98,167.

The invention is a lamp that is particularly adaptable for brakemc-n or railroad employees, and which may be removably attached to a band on apersons wrist and supplied by current :trom a battery in a pocket on a. belt.

The object of the invention is toprovide a light that does not have t0 be carried, and which is at the same time readily removable from the body.

A further object of the invention is'to provide a light that may be readily attached to any part of the body, and readily lighted from a common point.

provide a lamp that may be attached to the body, and readily adjusted to any suitable position.

And a still further object of the invention is to Yprovide a readily detachable body lamp which is of a simple and economical construction.

Vith these ends in view the invention embodies a tubular lamp casing having a at the inner end, a socket into which the said tubular casing may be sprung and held, means for attaching the socket to any suitable part of the body, a battery, a. switch on the battery, a belt in which the battery may be placed, and means for connecting the said battery to the said lamp socket.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings, wherein: y

Figure 1 is a view showing the device as it would appear in use.

Figure 2 is a plan view showing the lamp casing and socket.

Figure 3 is a similar view showing an alternate design, in which two lamp sockets are used instead of one.

Figure 4 is a longitudinal section through the lamp casing and socket for holding the said casing. Y

Figure 5 is a cross sectionl through the socket showing a spring for holding the lamp casing therein.

In the drawings the device is shown as it would be made wherein numeral 1 indicates the lamp casing` numeral 2 the socket and numeral 3 the battery.

The casing 1 is made as shown with a socket 4 at the outer end, having a reflector 5 held therein, and a tongue 6 at the inner end lamp.

A further object of the invention is to lamp socket in the outer end, and a tongue with a notch 7 in the lower side, and a contact point 8 at the end. It will be noted that the contact point 8 is insulated from the casing and connected to another vcontact point 9 at the opposite end of th-e casing, through a wire or rod 10. It will be noted that the lamp base will contact .with the casing through the socket 4 and the contact pointvatA the bottom of the lamp base will engage the contact point 9 at the base of the The contact point S will engage another point 11 in the cnd of the casing and the exterior' of the casing will 'form a contact with they casing 2.

The casing 2 is providedl with a boss 12 to which a double wire cord 18 is attached, and one wire of the cord is grounded to the casingl as shown at the point 14, and the other wire is connected to the contact point 11. The casing 2 is provided with a socket 15 having a spring 1G in the lower side, and it will be observed that as the 'tongue 6 is placed into the socket 15 the notch 7 will pass over the spring 16 so that the spring will snap into the notch to positively hold the tongue of the casing 1 in the socket. The tongue may readily be released by pressing the outer end of the spring 16 downward. In the design shown the casing@ is provided withloops 17 by which it may be attached to a wrist band or the like.

The battery 3 maybe of any suitable type or size, and may be held in a pocket 18 in a belt 19, as shown in Figure 1. Thepocket 18 may be of any suitable shape or design, and the contacts with the battery may be arranged in any suitable manner. The pocket is provided with a switch 2O which may be arranged to light the lamp on either hand or on the cap, orto extinguish all the lamps. However, it is understood that should only-one of the lamps be sed the switch may be adaptable to light only one lamp, or any combination of lamps. it will be observed that the cords 13 will extend from the pocket 1S to the individual lamp sockets through the clothing. These cords may be of any suitable length and arranged in any suitable manner to permit the lamps to be changed from one position to another, as may be desired.

It will be understood that changes may be v` made in the construction without departing from the spirit of the invention. One of which changes may be in the design of the lamp casing, another may be in the design or Ystood from the foregoing description.

arrangement of the socket or in the means of attaching the lamp casing to it, and still another may be in the design, arrangement or position of the battery. I Y

The construction Will be readily under- To use the device it may be arranged as shown, and it will be observed that when it is not in use the lamp casing may readily be removed from the socket 2 and placed in a pocket, and only placed in the socket when it is desired to use it. The lamp may then be lighted by the switch 20, as may be desired.

Having thus fully described the invention, what I claim as new and desire tosecure by Letters latent, is: A

l. In a railway lamp, a. detachablelamp casing, a socket in which the lamp casing may'readily be held, a spring latch in the.

said socket for readily holding the end of the said lamp casing, suitable contactpoints in the said socketadaptable to engage corresponding contact points on the end of the said lamp casing, suitable Wires extending from the contact points at the end of the said lamp casing through the said 'casing and connecting to the lamp socket to light the lamp, and a suitable two Wire cable eX- tending from the contact points 1n the said socket, means for attaching the socket to a' lighting the said lamp vas desired.

2. In a lamp, a tubular casing, a lamp socket in the outer end of the casing, ay tongue at the inner end of the casing, Contact points on the said tongue, suitable electric connections from the contact points on the tongue to the lamp socket through the tubular casing, a socket into which the said tongue may be placed7 contact points in the said socket corresponding with the Contact points of the tongue, means for holding the tongue in the said socket, means for attaching the socket to a part of a persons body, a battery, means for attaching the battery to a part of a personls body, and means for connecting the said contact of the socket to the said battery.

Y In testimony whereof he aiiixes his signature.
