BURNER-SHAFT HANDLE.

Specification of Letters Patent.

Application filed March 16, 1917. Serial No. 155,324.

To all whom it may concern:

Be it known that I, Ennns'r C. Evnnn'rr, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented anew and useful Improvement in Burner-Shaft Handles, of which the following is aspecification.

This invention relates to wick raiser devices for use on various types of lamps and lanterns, and has for one object to provide a device of this character of simple and efiicient construction, which can be inexpensively manufactured, and by means of which fine adjustment of the wick of a lamp or lantern can be effected.

Another object of the invention is to pro.- .vide a device of this sort which can be readily used in connection with tension means of the kind commonly employed for preventing the wick shaft from being turned by accidental jarring or striking of the lamp or lantern on which it is mounted.

Other objects and advantages of the invention are hereinafter described.

In the accompanying drawings:

Figure 1 is a front elevation of' the lower portionof a tubular. lantern provided with a wick raising mechanism embodying the invention.

Fig. 2is a fragmentary elevation thereof on an enlarged scale showing the finger piece of the wick raising mechanism and the tension means therefor.

Fig. 3 is an elevation of the wick raiser shaft detached. from the lantern.

Fig. 4.- isa rear elevation of a driving or carriage lamp having the wick raising mechanism mounted thereon.

Fig. 5 is a side elevation of the lower portion of a railway lantern, showing the preferred arrangement of the wick raising mechanism and tension means thereon.

Fig. 6 is a fragmentary top plan view partly in section of the construction shown in Fig. 5, the oil font being shown removed from the lantern.

Fig. 7 is a side elevation ofanother arrangement of the wick raiser device and tension means on a railway lantern.

Fig. 8 is a fragmentary top plan view, partly in section, of the construction shown in Fig. 7.

Referring to FigsQl-3, 9 represents the oil font of a tubular lantern, having tubes 10, air chamber 11, and globe plate 12, of well known construction. 13'is awick raiser shaft which is mounted on the lantern in the usual way, and preferablyhas the toothed wheels or disks letsecured thereon and adapted to engage with the lantern wick to raise or lower'the same when the shaft is turned. Any other suitable means for con necting the wick and the raisershaft can be utilized if desired, in place of the wheels or disks 1-1.

The finger piece or operating member of the shaft 13 is formed by bending th'eend of the shaft to form a substantially annular of circumferential rim portion 16, lying in a plane at right angles to the plane of the wick raiser shaft 13, the rim portion 16 being joined with the wick raiser shaft by means of a radially bent portion 17' lying substantially in the plane of the annular rim portion. This method of forming the finger piece on the wick raiser shaft is extremely economical, the wick raiser shaft 13 be ing constructed ofwire which can be readily bent into the desired shape, and the possibility of the finger piece becoming detached from the shaft, as is often the case when the parts thereof are formed separately is eliminated'. The extremity of the portion forming the rim 16 is preferably connected with the adjacent surface of the radially bent portion 1?. In the manufacture of the burner shafts, it is customary after the shafts are formed, to dip them in melted tin, in order to give anon-rusting finish. During this operation, enough tin adheres to the shaftto close the joint between the extremities of the rim portion 16 and the adjacent surface of the radial portion 17, as indicated at 16 In this way a stronger construction results than is the case when the portions mentioned are not connected. The circular form of the finger piece being in a plane transverse to that of the shaft aids the operator materially in effecting any desired adjustment of the lamp wick and there are no protruding points on the finger piece to catch in the clothing of the operator.

In order that the wick raiser shaft may not be turned by accidental jolting or'jar rin of the lantern, tension means are preferably provided which may be mounted on any desired part of the lamp or lantern, and which bear against the finger piece and fric' 18, which as used on a tubular lantern, is-

suitably curved and has one end thereof secured to the globe plate 12 111 any usual manner and the other end bearing against the inner side of the rim 16 ofthe finger piece. The strip exerts sufficient spring pressure against the finger piece to prevent the shaft from being moved accidentally, and yet does not interfere with rotation of the shaft and finger piece by hand.

WVhen the device is used in combination with'a carriage lamp, as shown in Fig. 4, thetension strip 19 is mounted on the rear casing 20 of the lantern, and bears against the inner surface 21 of the finger piece 22 in the same way as when used on the tubular lantern. I

Referring to Figs. 5-8, which show a wick raiser mechanism and tension means used in connection with a well known form of railroad lantern, 23 represents the upright lantern guards which are secured to a horizontal flat ringguard 24 and to another ring guard 25. 26 is the body hoop of the lantern and 27 is the oil font. All these parts are well known in the art. Figs-5 and 6 show the preferred arrangement of the tension means on the lantern. In the construction shown in these figures the strip 28 is secured in any well known way to the outside wall of the font 27 and is of suitable curvature so as to bear against the inner surface of a finger piece 29, formed at the end of the shaft 30 as aforedescribed.

Figs. 7 and 8 show another form in which the invention may be applied to a railroad lantern. In the construction shown in these figures, one end of the curved tension strip 31 is attached to the guard ring 2110f the lantern in any suitable manner, and the opposite end of said strip bears against the rim 32 of the finger piece.

29* represents the joint which is preferably formed between the extremity of the rim portion of the fingerlpiece, and the adjacent surface of the radially bent portion of the shaft. Such joint is preferably formed while the shafts are being tinned, as heretofore described.

I claim as my invention 1. In a wick raiser mechanism for lanterns, a rotatably mounted wire wick-raising shaft having one end thereof bent and forming a substantially annular finger-piece disposed substantially concentric with said shaft and in a plane at substantially right angles to the plane of the shaft, and a connecting portion which joins said annular finger piece to said shaft and is integral with said shaft and said finger piece.

2. In a wick raiser mechanism for lanterns, a wire shaft having one end thereof bent into substantially annularform in a planeat substantially right angles toithe plane of the shaft and having a radial, portion connecting said annular'portion with said shaft, said radial portion being formed integral with said shaft and said annular portion. V

3. In a wick raiser mechanism for 12111? terns, a wire shaft having one end thereof bent into substantially annular form in a plane at substantially right angles to the plane of the shaft and having a rad alpon tion connecting said annular portion with said shaft, said radial portion.,beingformed integral with said shaft andsaid annular portion, and the extremityof said shaft being secured to theadjacent surface of said radial portion. 7

Witness my hand this 12th day of March, 1917. V
