MINERS HAND-LAMP. I

Specification of Letters Patent.

Application filed October 12, 1917. Serial No. 196,104;

T 0 all whom it may concern:

Be it known that I, JOHN LAWRENCE Corr WAY, subject of England, residing at 21 Upper Albert road, Heeley, Sheffield, 1n the county of York, England, have invented new and useful Improvements in Minersliland- Lamps, of which the following is a spec1ficafor a spindle for regulating the flow of water from the upper vessel to the lower, to project through a hole in the top of the water vessel, and at a little distance therefrom a water filling hole is provided closed by a screwed pressed cap. My invention conslsts 1n an improved form of construction of the looking bridle and the means for secur ng to gether the water vessel and the carbld container.

My invention will be better understood on reference to the accompanying two sheets of drawings in which:

Figure 1, Sheet 1, is a slde V ew of an acetylene hand lamp made accordlng to my invention.

Fig. 2, Sheet 2, is a rear view of same.

Figs. 3 and 4: are a sectional plan view and elevation respectively of one of the angular pivoted brackets I employ in connectlon with the means for releasing the water vessel from the carbid container.

The same letters refer to similar parts throughout the several views.

According to my invention I form my improved form of bridle a, readlly detachable from the lamp when required but when in place the two ends of the bridle, each of which has a hole formed in it, are sprung over two pivots b, 79 situated one at each side of the carbid container 0, the pivots 7), b engaging in the holes in the bridle 0;. Fixed on each side of the water vessel ol, and vertically in line with the pivots b, 6 on the carbid container 0, are ears e, 6 each having the lower edge turned up in the form of a lip with a cambered edge 6 which edges are intended to engage wlth the shanks of studs f, 7, secured to the inner sides of the bridle a. These studs f, 7, are so placed on the bridle a, that as it is raised to a central 'vertical'position the heads of the studs, passin'side the lips on the ears 6,

c and as the bridle approaches its highest posltlon as shown in dotted lines in Fig; 1

the shanks of the studs engage with the cambereded'g'es c of the lips, until when th'e'bridle a, is quite vertical the pressure between the studs 7, f and the ears 6, e is such that the water vessel d, and the carbid container 0 are held securely together, thus insuring a gas tight joint between the two. The bridle a, is retained in its upright position by means of sliding clips g, 9 which encircle the side members of the bridle and which also engage with outstanding lugs h, if, on the top portion of the ears 6, 6 when the bridle is vertical.

Though I have described the position of the ears 6, 6 as being on the side of the water vessel, they may if desired be placed on the top of the vessel.

In connection with the above described bridle a, I employ means for releasing the water vessel d, from the carbid container 0, should such parts become stuck together due to the pressure to which the joint with its rubber packing ring is subjected, and to the presence of the carbid in the container. These means may be the same as are at present employed for the purpose which consists in the formation of each end of the bridle with a sidewardly projecting pointed nose, which when the bridle is turned down, engages with a flanged cover on the water vessel and on the continued movement of the bridle, forces the water Vessel ofi the carbid container. But by preference I should make the ends of the bridle a, quite plain, and on the same pivots Z), 6 about which the bridle a, turns,

Patented Oct. 28,1919.

I provide detachable angular pivoted brackets 2,71 each having a pointed nose i adapted to bear against the flanged cover of the water vessel (Z, when the bridle a, is turned downward. The motion of the bridle is imparted to these last named brackets i, 11 by reason of right angular flanges 2' on the latter bearing against one side of the bridle a, the movement of which in one direction causes the brackets to be tilted and to force the water vessel apart from the carbid container. But I lay no claim to novelty with regard to the mechanical principle involved in this arrangement for separating the two vessels.

Having now described my invention what I claim as new and desire to secure by Letters Patent is 1. An acetylene lamp, comprising a carbid container, a water vessel on the container,.a detachable bridle pivoted on the container and detachable angular brackets cooperating with the bridle for forcing the vessel apart from the container.

2. In miners acetylene hand lamps having an upper water vessel and a lower carbid container with a detachable bridle secured to the latter the combination with said bridle of detachable angular pivoted brackets cooperating with the bridle for forcing the water vessel apart from the carbid con- 1i;
