BLOWPIPE.

. SPECIFICATION forming part of Letters latent No. 617,729, dated January 17, 1899. Application filed March 11,18 ,8. Serial lio- 678,505. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM S. FILLEY, a citizen of the United States, residing at Montpelier, in the county of Williams and State of Ohio, have invented new and useful Improvements in Blowpipes, of which the following is a specification. I

My invent-ion relates to blowpipes in which carbureted air is employed both as the medium for producing the flame and as the jet fordirecting the flame and concentrating the heat upon any particular point; and the invention consists in the novel construction and combination of parts hereinafter fully described and claimed.-

In the accompanying drawings, Figure 1 is a longitudinal sectional view of a blowpipe constructed in accordance with myinvention. Fig. 2 is a horizontal section on the line a: :r, Fig. 1.

In the said drawings the reference-numeral 1 designates a handle,of any suitable material,

having a central recess 9, in which is located a vertical tube 3, secured in place by a screwthreaded socket 4, fitting on the upper end of said handle. Intermediate its ends said tube is formed with a lateral pipe 5, the outer end of which is provided with a hose 6, connected with any suitable carbnreting-niachine. Said pipe near its inner end is connected by an in clined passage 7 with a valve-casing 8, parallel with the pipe 5, but extending beyond the opposite side of tube This valve-casing is connected by a passage 9 with a Bunsen or other burner 10 and at its lower end is formed with holes 11 for the admission of air. This burner may be of any ordinary construction, and a detailed description thereofis notnecessary. Located in said casing is a needlevalve 12 for opening and closing communication between the same andthe passage 9. At the outer end the-casing is provided with a screw-threaded cap 13, through which passes the outer end of the needle-valve, provided with a hand-wheel 14. Said needle-valve intermediate its ends is screw-thrczuled to enengage with conresponding serew-rhrcads in the end of said casing.

The numeral 15 designates a packingwing interposed between the end of the casing and the cap 13.

The numerals 16 and 17 designate r'eniovable screw-plugs engaging with. threaded holes in the casing S and passage 9.

Located in the tube 3 is a verticalLv-mov- 5 5 able rod 18, provided at the upper end with a stem 19, to which is secured a cylindrical valve 20 for opening and closing communication between said tube and the pipe 5. Located on said tube is a vertically-movable 6o collar 21, provided with a thumb-screw 23, the shank or stem of which passes through a hole in said collar and engages with the rod 18. The tube 3 is formed with a vertical slot 24 to allow the said thumb-screw to move up 6:, and down. l

The numeral '25 designates the jet-pipe at the upper end of tube 3. a

The operation will be readily understood. Qarburetcd air is forced from any suitable 7o carbureting-machine to the pipe 5, and valve 20 being opened said air will escape to the burner, where itis ignited. At the same time the needle-valve 1) is opened to admit'alii' also from said pipe to the tube 3 to furnish the jet or blast.

Having thus fully described my invention, what I claim is 1. In a blowpipe, the combination with the handle, the tube secured thereto, the lateral 8 pipe connected with said tube, the valve-cas ingconnccted and communicating with said pipe, the needle-valve located in said casing and the burner connected with the casing, of the vertically-movable rod located in said 8; tube, the circular valve at the upper end of said rod, and means for operating the same, substantially as described.

2. In a blowpipe, the combination with the handle, the tube connected therewith, the laton oral pipe connected with said tube, the valvecasing connected with said pipe, the needle valve, and the burner connected with said casing, of the vertically-movable valve located in said tube, the rod connected therewith, the collar on said tube, the thumb-screw passing therethrough and through a vertical slot in said tube and secured to said rod, substantially as described.

In testimony whereof I' have hereunto set for my hand in presence of two subscribing witnesses.
