SPECIFICATION forming part of Letters Patent No. 430,196, dated June 17, 1890. Application filed September 20. 1888. Serial No. 285,945. (No model.)
To aZZ whom it may concern:
Be it known that we, BENNARD REIN, a citizen of the United States, and a resident of the city of Detroit, county of Wayne, and State of Michigan, and ASA IV. STRAIGHT, a resident of the city of Ypsilanti, county of WVashtenaw, and State of Michigan, have invented certain new and useful Improvements in Plumbers or Jewelers Furnaces, of which the following is a specification.
Our invention consists in certain details of construction whereby the hood may be re moved and the burner turned from its nominal position, so that it can be used as a paintbreamer.
In order that our invention may be fully understood, we will proceed to describe its construction in detail, reference being had to the accompanying drawings, which form a part of this specification, and in which like letters refer to like parts throughout the several views.
Figure 1 is a perspective View of our invention as a fire-pot for heating light irons or melting metal when placed in the removable pot of the hood A. Fig. 2 is a perspective View of our invention as an open forge for doing hard soldering, brazing, or using as a paint-breamer, &c. Fig. 3 is an enlarged view of the generator 0. Fig. 4 is a sectional view of the generator, also showing the needlepoint N.
A is a hood as a whole.
B is a tank for gasoline and air.
0 is a standard on tank B for holding the hood A. I
D is a bail on hood A, and by which the furnace may be carried.
E is a tube through which the gasoline passes to the generator, one end of which tube rests on or near the bottom, on the inside of the tank B, the other end passing up through the top of the tank B and terminating in or having an elbow attached thereto.
F are braces to hood A.
G is a hollow tube, through which the main shaft j, the end of which terminates in the needlepoint, passes.
H is a sleeve to hood A, and through which the tube or standard C passes.
I is a wheel for operating the valve of the air-pump.
J is a Wheel for operating shaft j, the end of which terminates in a needle-point.
-K is a drip-cup on the under side of generator O.
L is the main vein from the generator to tube E.
.M is an opening from the veins to the needle-point.
N is a swivel-joint connecting the generator to the tube E.
O is the generator as a whole, including the main vein or sleeve L, to which the swiveljoint is attached.
P is a vein on generator 0, through which the gasoline passes after leaving the sleeve or tube L on its way to the opening M.
Q are plugs in the ends of the veins, which may be removed to clean the veins should they become clogged.
R is that portion of the generator that the shaft on which is the needle-point passes through.
S is a slot inthe generator, which admits of the vapor-tube I) being set at the required distance from the needle-point, as the farther the vapor-tube is from the needle-point the stronger the blast.
T is an elbow or that portion of the tube E to which the swivel-joint is attached.
U is a rubber bulb or air-pump.
WV is a tube leading from the air-pump to the tank 13.
V is the neck of the air-pump.
X is a stem secured to the wheel I and passing into the tube WV, the purpose of which will be explained hereinafter.
Y is a projection on tube W, to which the air-pump or rubber bulb is attached.
Z are lugs on top of hood A, and on which a pot for melting metal may be placed.
1) is a screw-plug in tank B, which may be removed for filling the tank.
0 is a bail to the metal fire-pot cover.
f are set-screws, one for securing the swiveljoint to the elbow and one for securing the vapor-tube at the required distance to the needle-point, this screw passing through the slot S in the generator.
g is a lug upon bail D.
h is an opening in side of hood A, and in which the soldering-irons may be placed while heating.
j is a shaft, one end of which is secured to the Wheel J, the other end of which forms the needle-point. Along a portion of this shaft are cut threads, which work in threads out on the inside of the tube G. By this means the needle-point is drawn in or out by turning the wheel J, thus regulating the flow of the gasoline.
n is the needle-point.
p is a vapor-tube.
The operation of our furnace is as follows: Fill the tankB with gasoline or other oils to be used, and then close tightly, after which turn the wheel I to the left, or until the shank X is raised above the point of intersection of the projection Y with the tube WV, when by compressing on the rubber bulb the air is forced into the tank B. lVhen a sufficient quantity of air has been forced into the tank so that the pressure will cause the gasoline to flow up through the tube E, the wheel I is turned to the right, or closed. Now turn the wheel J to the left, or so that the needle-point is drawn in, thus allowing the gasoline to flow. When enough has escaped to fill the dripcup K, close the opening by turning the wheel J to the right. Now apply a light to the cup. The burning fluid will heat the generator, so that when the gasoline passes through the veins P it is heated to such a degree that when the wheel J is turned to the left again the gasoline escapes in the form of a gas or vapor instead of a liquid. Care should be taken after the fluid in the drip-cup has been ignited not to turn the wheel J so that any more gasoline can escape until after all that is in the drip-cup K is burned-out, when the wheel J may be turned to the left, causing a small opening at the needle-point a. When the heat from the generator causes the gasoline to escape in the form of a vapor, a lighted match applied at the point indicated by the figure 7 will ignite the gas, and by occasionally filling the tank with air a steady blast may be had. The volume or flow of the gas is governed by turning the wheel J. The farther the point a is drawn in the larger the flow, and vice versa. The blast may be governed by loosening the screw f in the slot S on top of the generator, and sliding the vaportube 29 to or from the point nthe farther from the point the stronger the blast. To change the fire-pot, as shown in Fig. 1, to an open forge, as shown in Fig. 3, remove the hood. Then by lifting the wheel J the burner as a whole may be turned upon the flexible or swivel-joint from the position shown in Fig. 1 to that shown in Fig. 3, in which position it is adapted for hard soldering, brazing, or for use as a paint-breamer.
Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is
A reservoir having an air-inlet tube and an oil-tube leading from near its bottom, in combination with the burner flexibly mounted on the oil-tube, and the detachable'support (the hood) for soldering iron or other articles, located above the burner, substantially as herein shown and described.
In testimony that we claim the above as our invention we have hereunto set our hands, at Detroit, Michigan, this 11th day of September, A. D. 1888.
