VICTOR H. SLINAOK, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE PENNSYLVANIA GLOBE GAS LIGHT COMPANY, OF PHILADEL- PHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

INCANDESCENT STREET-LIGHT.

SPECIFICATION forming part of Letters Patent No. 776,360, dated November 29, 1904.

Application filed December 6, 1901. Renewed July 25, 1904. Serial No. 217,939.

To all whomit 'mrty concern.-

Be it known that I, VICTOR H. SLINAOK, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Welsbach and other Incandescent Street-Lights, of which the following is a specification.

The principal object of the invention is to provide a VVelsbach or other incandescent street-light in which dust, bugs, insects, and the like will be excluded from entering the Bunsen tube, and thus interfering with the proper working of the burner.

Other objects are to provide for simultaneously controlling the admission of gas and air to the Bunsen tube and for effecting such operations from a single point easily accessible to the operator.

To the ends stated the invention consists in the improvements hereinafter described, and pointed out in the claims.

The nature, characteristic features, and scope of the invention will be more clearly understood from the following description, taken in connection with the accompanying drawings, forming a part hereof, in which Figure 1 is an elevational View of the upper or head portion of a WVelsbach street-light embodying features of the invention. Fig. 2 is a sectional view of the same, drawn to a larger scale, showing the general arrangement of the parts. Fig. 8 is a plan view of the lantern-base, and Fig. 4 is a sectional view of the Bunsen tube and its air shutter or casing.

In the practice of the invention the Bunsen tube is extended into the socket of the lantern-frame or the head of the lamp-post and made to take its supply of air from that which enters the post through the joints and crevices thereof'for instance, through the head or socket of the post. The general construction, arrangement, and operations of the parts may be stated as follows.

Referring to the drawings, 1 indicates the gas-supply pipe, which for purposes of the invention terminates inside the socket 2 of the lantern-frame, where it is provided with a gas-valve 3, which usually occupies a position (No model.)

above the lantern-base. The lantern-socket 2 is in effect a continuation of the lamppost. The valve 3 is of the common plug type, and is arranged to communicate with the needlevalve 4: and with the pilot or climbing lighter 5 in the well-known manner. The yoke 6, which supports the needle-valve, also serves as a bottom support for the Bunsen tube 7, the connecting parts being threaded for ready detachment. The Bunsen tube passes through a ring or collar 8, which it supports, and which occupies the position above the lantern-base that is ordinarily assumed by the gas-valve. The Bunsen tube is extended at its base, where it is provided with openings 9, through which more or less air is admitted to the tube, the supply being governed by an air-shutter consisting of a loosely-mounted shell or tubular casing 10, which closes that portion of the Bunsen tube between the yoke 6 and the collar 8. The tubular shutter or casing 10 is provided with a number of series of orifices 11, which can be made to register with the openings 9 of the Bunsen tube by imparting a slight rotary movement to the shutter.

The collar or member 8 is provided with a projecting pin or screw 12, which acts as a fulcrum for an operating-lever 13, having a circumscribed arc of movement that is defined by fingers 14, movable against a stop or detent15. Thelever 13 carries a pawl 16, which has pivotal connection therewith and can be made to engage the stop 15 to hold the lever in a depressed position. The lever 13 is operatively connected with a crank or arm 17 of the gas-valve by means of a link 18. The latter is provided with a projection 19, carrying a pin 20, which is arranged to work in an angular slot 21 of the air shutter or casing 10. Thus the lever 13 constitutes a common actuator for the means for controlling the supply of air and the means for controlling the supply of gas.

In practice the operator thrusts his torch through the opening 22 of the lantern-base and pulls down the lever 13, in which lowered or depressed position the lever 13 is held by the pawl 16, engaging the detent 15. Thus operated, the lever 13, through the instrumentality of the link 18, actuates the gas-valve to permit gas to flow to the pilot 5 and to the burner 23. At the same time the link 18, by reason of its pin-and-slot connection with the tubular shell or air-shutter 10, serves to rotate the same sufficiently to cause the openings 11 therein to register with the openings 9 of the Bunsen tube and air is admitted to the latter from the post. Manifes'tly the gas-. supply is cut off and the air-shutter adjusted to close the openings in the Bunsen tube when the position of the lever 13 is reversed by tripping the pawl 16. The air shutter or casing is a valuable adjunct, as it operates to effectually keep out dust and also bugs and insects, which during the day congregate inside the post. At night of course they are attracted by the light of the burner and make their way toward the same, so that there is little or no danger of their trying to enter the Bunsen tube.

The needle-valve 4 can be adjusted manually through an opening in the post that may be closed in any convenient manner-for instance, by the door 26. (Shown in Fig. l.)

The lantern-base is provided with means for adjustably supporting the draft-tube 24:, the

latter being guided on a rod 25, adjustably supported by the collar 8.

It will be obvious to those skilled in the art to which the invention appertains that modilications may be made in details without departing from the spirit and scope of the same. Hence I do not limit myself to the precise construction and arrangement of parts hereinabove described and illustrated in the accompanying drawings; but,

Having described the nature and objects of the invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a street-light, the combination of a lamp-post having a lantern the socket of which constitutes a continuation of the post, a Bunsen tube having its air-inlet arranged interior of the lantern-socket, gas-supply connections, and means for controlling the supply of gas and air from a point outside the post, substantially as described.

2. In a street-light, the combination of a lamp-post having alantern the socket of which constitutes a continuation of the post, a Bunsen tube having its air-inlet arranged interior of the lantern-socket, gas-supply connections, and means for simultaneously controlling the supply of gas and air from a point outside the post, substantially as described.

3. In a street-light, the combination of a lamp-post having a lantern, a Bunsen tube extending into the socket of the lantern and arranged to take air therefrom, gas-supply connections, means for controlling the supply of gas and air, and an actuator for said means, substantially as described.
