SAFETY-TANK AND AUTOMATIC FILLER.

SPECIFICATION forming part. of Letters Patent No. 339,106, dated March 30, 1886.

Application filed February 25, 1884. Serial No. 121,905.

To all whom it may concern.-

Be it known that I, BENJAMIN S. 11011., a citizen of the United States, residing at Salem, county of Columbiana, State of Ohio, have invented or discovered a new and useful Iniprovement in Safety-Tanks and Automatic Fillers; and I do hereby declare the following to be a full, clear, concise, and exact description thereof, reference being had to the ac companying drawings, making a part of this specification, in whichlike letters indicating like partst Figure 1 is a vertical central section of my improved safety-tank and filler. Figs. 2 and 3 aresiniilarviews ofa modified form of tank, the filler being removed in Fig. 3. Fig. 4 is a like view of another form of tank, and showing a modification of the valve operating mechanism. Fig. 5 is a top view of the filler, the handle and valve-operating mechanism being shown in section. Fig. 6 is a detail view, on an enlarged scale, showing the filling-nozzle of the filler.

My invention relates to tanks or receivers to be used in connection with gasoline-stoves and a filler to be usedin connection with said tank, and the object of my invention is to so construct and combine the tank and filler as to avoid all danger of explosion, either in filling the tank or drawing the fluid therefrom; and to this end my invention consists in the construction and combination ofparts,all as more fully hereinafter described and claimed.

My preferred form of tank, A, consists of the top and bottom parts, 1 and 2, made of castiron or other suitable metal, and the sheetmetal side 3, secured in any suitable manner with a peripheral recess in the top and bottom parts, 1 and 2.

At one side of the top 1 is formed the opening 4, and in the top around the opening 4 is formed the annular flange 5. Inside of this flange the top slopes in toward the opening 4, around the edges of which is formed the recess 6, adapted to receive the flange of the ring 7, one end of said ring being covered by a piece of wire-gauze, 8, to prevent any flame from passing into the tank.

Within the ring 7 is placed another ring, 9, across which is stretched a piece of chamois- (No model.)

skin, 10, to strain the fluid as it enters the tank A. 1

In the bottom of the tank is formed an opening, 11, intowhich is screwed the pipeleading to a burner, and the bottom is made to slope from the sides toward the opening 11, in order that all the fluid may escape therefrom.

Around the flange 5 is secured one end of the sheet-metal cylinder B, which I will term the receiver. The top of this receiver B is provided with a cast-iron rim or ring, 12, provided with an internal recess, into which the end of the cylinder fits, and an external flange or ledge, 13. On the side of the receiver is secured a graduated plate, 14., along which moves pointer 15, attached to a rod, 16, passing through a tube, 17, inserted in the top of the tank A, and to the end of the rod within the tank is secured afloat, 18. By this device the quantity of fluid within the tank can be readily ascertained.

As both the tank and receiver may occasionally be filled, it is necessary that the tube 17 should be extended to a height equal to that of the receiver, and in that case the upper end of the rod is bent so as to bring the pointer into proximity to the graduated plate. The ends of the tube 17 should be provided with stuffing-boxes,or other suitable devices, to prevent any flame from passing down the tube and the escape of any gas therefrom.

Within the receiver B is placed the filler D, which consists of cast-iron top and bottom plates, 19 and 20, each provided with flanges 21 and 22, having a peripheral recess to receive the ends of the sheet-metal cylinder 23, forming the sides of the filler. The bottom plate, 20, is internally dished,and is provided with a screw-threaded socket, 2 1, in its center, into which is screwed the perforated plug 25, the inner end of said plug being constructed to form a seat for a valve, as hereinafter described. The top plate, 19, is extended circumferentially beyond the flange 21, said extension being provided with a flange, 26, parallel with the flange 21, and adapted to rest on the flange 13 when the filler is placed in the receiver. A rubber gasket may be placed on the flange 13, so as to pack the joint between it and the flange 26.

In the top plate, 19, at one side of its center, is formed the recess 27, having sloping sides and provided with the filling-nozzle 28, which is stopped by the stopper or plug 29.

On the top plate, 19, is secured the cast-iron case E, for-inclosing the valve-operating mechanism, and having the handle 30 formed integral therewith, for lifting and conveying the filler. At the ends of the case E are arranged the sliding bolts 31, having their lower ends projecting down through openings in the top plate, 19, between the flanges 21 and 26. These bolts are guided during their vertical movements by pins 32, which pass through slots 33 in the bolts and are secured to the sides of :the case E.

In theinner edges of each bolt 31 is formed-the recess 34. In to these recesses fit the correspondingly-shaped ends 35 of the levers 36, pivoted on the pins 37, secured in the sides of the case. The opposite ends, 38, of these levers, similar in shape to the ends 35, fit into recesses 41in the ends of the levers 39, pivoted in pins '40, secured similarly to the pins 37. The opposite ends, 42, of these levers are reduced and rounded to fit into correspondingly-shaped recesses 43, formed in each end of the block 44.

Through a vertical opening in the block 44 passes the reduced end of the rod 45, which is secured in said block by a pin or screw, 46.

On the reduced end of the rod 45, projecting above the block 44, is placed the spring 47, whose ends bear against the block 44 and the top of the case, and (end to force the block and rod down. This rod 45 extends through a hole in the top plate down to the bottom of the filler, its lower end being provided with a valve, 48, adapted to fit the seat in the plug 25. This valve is attached to the rod by a ball-and-socket joint, 50, and is provided on its lower side with a guide-stem, 49, to insure its exact seating on the plug 25.

On the bottom plate, 20, are formed the rimlegs 70, to support the filler when removed from the receiver.

In Fig. 4 the tank and receiver areshown arranged one above the other in a long cylindrical vessel, F, of uniform size, having a flanged concave-convex bottom plate, 52, and a cast-iron top ring similar in shape and construction to the ring 12.

Within the vessel F, about midway of its length, is secured the ring 53, on which rests the ring 54, to the opposite edges of which are secured the wire-gauze and chamois-skin diaphragms 8 and 10. Within this cylindrical vessel is used a filler similar in construction and operation to the filler D; but in place of the indicator above described I use the ordinary glass gage, 55, connected at its upper and lower ends to the tank. Within the glass tube of the gage is placed ball 56, of pith or other buoyant material, and to the tank, within the range of the pith ball 56, is secured the graduated plate 14.

In Figs. 2 and 3 the tank and receiver are combined, forming a vessel, H, only slightly by inclined planes 6?.

longer than the receiver shown in Figs. 1 and 4. Within this combined tank and receiver is arranged a movable diaphragm or piston, 57, concave on its upper surface, and provided with a central aperture, 58, across which is placed a piece of wire-gauze. This piston 57 is normally held in an elevated position (shown in Fig. 3) by the spring 59, secured at one end to the bottom of the vessel. The registering device of this vessel issimilar in some respects to that shown in Fig. 1; but in place of arranging the float within the tank it isplaced in a tube, 60, connected at its lower end to the tank by the pipe 61. In all other respects the register is constructed and operated like the one described in connection with Fig. 1. When the fillerD is placed within the vessel H, it depresses the piston 57, as shown in Fig. 2; but when the filler is removed the spring forces and holds the piston above the level of the fluid therein, thus protecting it against any flame that may be brought near the tank.

In Fig. 4 I have shown a modified form of valve operating mechanism, constructed as follows: On top of the sliding bolts 31 is placed the spring 62, having a downward tension. The levers 36 are given a bell-crank shape, and between the levers 36 and the levers 39 is arranged a slide, 63, supported and guided I by the pin 64, passing through the slot 65. These slides are connected to the levers 36 by a joint similar to that connecting the levers 39 and 36 in Fig. 1, and are provided on their upper edges with the straight portions 66, ar-

ranged in different planes vertically connected The outer ends of the levers 39 are provided with the projections 68,

which rest upon the upper edges of the slides 63, as shown. The inner ends of these levers are connected to the block 44 in a manner similar to that shown in Fig. 1, and this block attached to the rod 45 by a screw or pin, 46, as above described. The outer ends of the levers 39 are held against the slides 63 by the springs 69, as shown.

The tank above described is placed on a shelf or support in convenient proximity to the burners which it is desired to use, and connected thereto by a pipe leading from the bottom of the tank. Then the filler,having been filled with fluid through the nozzle 28,is placed in the receiver, as shown, the upper edge of the ring 12 extending between the flanges 21 and 26, strikes against the bolts 31, which project a short distance into the recess between the flanges, thereby causing them to rise. These bolts in moving up operate the levers 36, and these in turn operate the levers 39,aud their inner ends raise the block 44 against the tension of the spring 47. This block carries with it the rod 45, to which the valve 48 is attached,thereby unseating saidvalve and allowing the fluid to escape into the receiver, where it passes into the tank or pipe leading to the burners through the gauze and chamois diaphragms. When the filler is removed from the receiver, the motion of the valve-operating mechanism is reversed, and the valve is light- 1y held against its seat, and the filler can be carried to any place where it can be filled.

The operation of the mechanism shown in Fig. 4 is similar to that above described, with the exception that the levers 36 move the slides 63,and they in turn operate the levers 39. The efl'ect in both forms of construction is the same. It will be seen that in using my device all exposure of the gasoline when in proximity to the flames is avoided, the wire-gauze protecting the fluid in the tank or receiver when the filler is in use.

In the forms of tank and receiver shown in Figs. 1 and 4 I may, after having emptiedthe filler into the tank, remove the filler and again fill it and replace it in the receiver.

Although I haveshown several forms of tank and receiver, I prefer to use the form shown in Fig. 1, as that form is lower andhasabroader base, and is therefore less apt to be upset.

I claim herein as my invention- 1. A storage-tank having, in combination, a reservoir for holding the liquid, a receiver for holding a fillingvessel while being emptied, and a diaphragm composed of wire-gauze and chamois-skin, substantially as set forth.

2. A combined reservoir and receiver, in combination with a diaphragm composed of gauze and chamois-skin and a spring, substantially as set forth.

3. A storage-tank consisting of a reservoir and receiver open at the top, in combination with a filling-vessel having asuitable outlet, a valve for closing said outlet, and a slide or bolt mounted at the top of the filling-vessel with its lower end in line with the upper edge of the receiver, and connections between the slide and valve, whereby the valve will be operated when the filling-vessel is placed on or within the receiver, substantially as set forth.

4. A storage-tank consisting of a reservoir and receiver, in combination with a filling-vessel having a suitable outlet, avalve for closing said outlet, a rod movably attached to the valve and provided at its upper end with block, system of articulated levers, and sliding bolts, substantially as described.

5. A storage-tank consisting of a reservoir and a receiving-chamber having the ring 12, with its upper edge projecting from the upper part of said chamber, in combination with a filler, D, having an outlet in its bottom, valve a8,spri rig-actuated rod 45,aslide or bolt mounted at the top of the filler, with one end inline with the upper edge of ring 12, and connections to rod 45, whereby the slide wil engage the ring and operate the valve when the filler is placed within the receiver, substantially as set forth.

6. A storage-tank consisting of a reservoir and receiver having the rim 12, in combination with a filler having a suitable outlet, the valve 48, rod 45, movably connected with the valve, the block 44, levers 39 and 36, and bolts 31, said block, levers, and bolts being pivotally connected, as described, and the spring 47, substantially as set forth.

In testimony whereof I have hereunto set my hand.
