UNITED STATES WILLIAM I. TARRANT, OF S ARATOGA SPRINGS, NEW YORK.

DISPENSING DEVICE.

Application filediseptember 19, 1921. Serial No. 501,655.

To all whom it may concern:

Be it known that I, IVILLIAM P. TARRANT, a citizen of the United States, and a resident of Saratoga Springs, Saratoga County, and State of New York, have invented certain new and useful Improvements in Dispensing,- Devices, of which the following is a specification.

This invention relates to devices for dispensing hot or molten material such as tar, asphalt or like substances.

In pavements or similar constructions where brick or concrete are used it is com mon practice to fill the joints or cracks with tar or asphalt. This process is rendered difficult because of the nature of the material used and because the material must be poured in a hot ormelted condition. Also it is very objectionable to have such material drip or continue to run from the dispensing device after the joint or crevice has been filled. A

One of the objects of the invention is, therefore, to provide means for efliciently dispensing hot material, such as melted tar or asphalt.

Another object of the invention is to provide a. dispensing device so constructed as to operate effectively and to cut off the stream of material dispensed, promptly, when the control valve is closed.

Another object of the invention is to provide a dispensing device, having its operative parts so arranged that the control valve may be burned out when it becomes clogged or gummed up, without injuring the other parts, such, for instance, as the valve clos ing mechanism.

Another object of the invention is to pro vide a dispensing device of the character described, having its control valve so located with reference to the outlet or dispensing nozzle that there will be substantially no drip when the valve is closed.

Another object of the invention is to provide a dispensing device, having its control valve so located as to be placed in the hot material, thereby heating the valve and rendering it easy to operate.

Further objects of the invention will appear from the following specification taken in connection with the drawings, which form a part thereof and in which- Fig. 1 is a perspective view, partly broken away, of a dispensing device constructed in accordance with my invention, and

Fig. 2 is a sectional detail view on an enlarged' scale, showing the valve construction and the valve operating mechanism.

Briefly described. the invention comprises a receptacle adapted to hold melted tar or asphalt, the receptacle having an outlet nozzle located at the bottom thereof and preferably at the lowest point of the bottom, which in this instance is sloping. The control valve for the nozzle is located at the bottom of the receptacle and the controlling means for the valve is located remote from the valve and in the embodiment shown is carried by a tubular member, which extends through a wall of the receptacle to the bottom thereof. The

valve is closed by a spring located at the outer end of the tubular member and the valve is opened by means of a handle connected to the valve by a rod, which extends through the tubular member.

Like characters of reference indicate cor responding parts throughout the several views of the drawings.

Referring to the drawings, I have shown a receptacle 10 substantially cylindrical in shape and having a downwardly sloping bottom 11. A supporting member 12 is secured to the bottom and co-operates with a nozzle 13 in retaining the receptacle in an upright position.

The nozzle 18, as illustrated, is located substantially at the lowest point of the receptacle and extends through the bottom. The flow of the melted material through the nozzle is controlled by a valve mechanism 14 carried by the nozzle and having a series of radial openings 15 which admit the material to the nozzle. A valve seat 16 is provided in the nozzde and a valve 17 is adapted to engage the seat and control the flow of the material through the nozzle. A tubular member 18 extends upwardly from the nozzle being connected to the nozzle at its lower end. The upper end of the member 18 extends through the wall of the receptacle 10 and this member houses or encloses a rod or link 1.9, which is connected at one end to the valve 17 and at its opposite end has secured thereto laterally projecting handles 20 In the present instance the valve is closed automatically by means of a spring 21, which is positioned between a collar 22 fixed to the rod and a pin 23 carried by the tubular member 18. Particular attention is called to the fact that this spring is located in a positionremote from the valve 17 since the valve may at times be clogged or gummed up by the asphalt or tar and when this occurs it is sometimes necessary to burn out the valve. If the spring were located near the valve this burning out process would take the temper out of the spring and render it no longer operable.

A transverse handle 24L is secured to or formed on the upper end of the tubular member 18 and in the upper embodiment of the invention illustrated the tubular member is shown as bifurcated and the handle is secured to the ends of the bifurcations.

.A bail orhandle 25 is also secured to the top'of the receptacle, and is used for transporting the receptacle.

A strainer 26 preferably formed of Wire meshis positioned in the upper end of the receptacle as clearly illustrated in Fig. 1.

From the above description itwill be seen that a simple and practical dispensing device has been provided and moreover that the parts have been so located with reference to each otherthatthey will operate most effectively and efiic'iently. By locating the valve at the bottom and within the receptacleit will be noted that the valve is so positioned that it will be heated by the hot or melted material and will, therefore, be easy tooperate. The location of the valve at the bottom of'the receptacle also facilitates prompt stopping of the flow of the material when the valve. is closed, thereby preventing the material from dripping.

Although one specific embodiment of the invention has been illustrated and described it willbe understood thatithe invention is capable of modification and that changes in the construction and in the arrangement of the various co-operating parts may be made Without departing from the spirit or scope of the invention as expressed in the following claims.

What is claimed is:

1. A dispensing device comprising a receptacle, a tubular member secured thereto and extending through the bottom thereof and abovexthe top of the receptacle, a valve in the tubular member located atthe bottom of the receptacle, spring closing means for said valve located Within the tubular memher and a valve control :rod extending through the tubular member and above the upper end thereof wherebythis rod maybe actuated to open the valve.

2. A dispensing device comprising azreceptacle, a tubular 1116111b8f880111i6d thereto and extending through the bottom of the receptacle and above the top thereof, said tubular member having lateral openings therein adjacent the bottom of ethejreceptacle and a valve seat between-said openings and the outletend ofxthe=tubular member, a valve mounted in the tubular member and adapted to seat on the valveseat, a valve control rod extending from said valve upward through the upper end of the tubular member and spring closing means for-said valve.

In witness whereof, I have hereunto-set my hand this 16th day of September, .1921.

WILLIAM P. TARRANT.
