CEMENT-POT.

Specification of Letters Patent.

Application filed.l December 5, 1908. Serial No. 466,108.

To all whom 'it concern:

Beit known that I, HORACE W. LAWSON, a" citizen of the UnitedV States, residing at Nashua, in the county of Hillsboro and State of New Hampsire, have invented certain new and useful Improvements in Cement- Pots; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it app'ertains to make and use the same.

The present invention relates'to cement pots. y

In the manufactureof shoes, many of the parts going to make up a shoe are united by cement, which contains a'great amount of naphthaor other highly volatile solvent. Such cement is usually shipped in barrels from which a quantity is removed to a. dispensing receptacle for use. Such dispensing receptacles are usually of` such size that they may receive a days supply so as to obviate the necessity of frequent replenishing from the original barrel. Further they must be so constructed as to prevent the evaporation of the mixture which would cause waste and an objectionable thickening of the cement, while at the same' time provision must be made for the convenient dippting and loading ofthe brush of the opera or.

-fIo` the above ends the present invention consists of the devices and combinations of devices hereinafter described and claimed.

The present invention is shown in the accompanying drawing in which F1 re 1 shows'a vertical sectional view of the evice,.the valve connecting the reservoir and the brushpan being in side elevation. Fig. 2 shows a top plan view of the cover for the brush pan, removed, and Fi 3g showsa cross section through the brus pan on a line diametrically opposite to that shown in Fi 1.

The device comprises a pot or reservoir 1 which may be of anfy suitable size and -shape and constructed o `any suitable material, that shown in the drawing being constructed of tin and being square in cross section.

At the top the-reservoir 1 is provided with an opening 2 surrounded by a vertically ex` tended threaded wall 3, engaged by a downwardly extending threaded iiange 4 yof a cover 5, which may be opened for filling and then tightly closed to,c protect the contents from evaporation. The cover 5 vided with the. handle 6.

Near the bottom Vthe pot 1 is provided .with al1 outlet 7, surrounded by a bushing 8, the inner surface of which is threaded to be enga 0*ed by thethreaded boss E.) of the 'cock or va ve 10 provided with the hand wheel 11, for opening and closing it. A nipple 12 connects the reservoir with the brush pan 13,

ithbeing screwed at one end into the valve and at theother into a threaded socket 14 in said pan.l The brush pan 13 is a brass casting circular in shape having in its upper surface a shallow basin 15 provided with an opening 16 at its center which leads to a vertical passage 17 connecting -with a horizontal passage 18 leading to the valve and through which a connection is made between the reservoir and the brush pan.

For lightness of construction the brush pan ma be cast with the recess 19 upon its under side surrounded by the ange A20, the passage 18 heilig formed in the transversely extended tube-like projection 21. The brush pan 13 is provided witha protective cover 22 which is ,also a brass casting and is provided with a downwardly extending flange ,23 arranged to closely fit the rabbeted upper edge 24 of the brush pan 13. The flange 2.3 is also rabloeted at25 to render the-joint the tighter. The space-'between the cover and the brush panholds the cement which flows into the brush pan from the reservoir.

may be pro'- The cover 22 is lower in the middle and has at its center a substantially level circular portion 27 provided with the comparatively small openings 28 which are contained within. a comparatively restricted area. It is surrounded with av comparatively low wall `or ange 29.

In use the operative lls his cement pot in the mornin with the proper amount of cement for a ays work and places it upon the bench alongside of him= where he works.

Then the valve is opened to anv extent sufcient to permit the flow of the desired amount of cement to the di ping pan as it is used. Thus a more rapid) operative may open the cock more, while a slower operative will open it less. This is usually determined by observing the flow of cementas it is used up. The cement fiows into the basin 15 and oozes up through the small holes 28. erably the flow is so regulated that the globules ormed at the ,mouth of these holes Prefl do not 'coalesce between the times when they 10 1saving has been found lin actual use to t amount to from forty to fifty percent. At

.the end of the days work -the operative closes the valve and takes off th l cover and cleans the pan, the cover and al of the eX- posed arts. y Then there being no evapora.`y tion, t e pot isready to be filled the nexty morning.

' Having thus described the invention, what is claimed is 1. A cement pot, having, in combination, a reservoir, a briush pan, a closed conduit connectin the' reservoir and brush pan, and

a cover or the pan having its outer por- .areservoiig a brush pan, a' fclosed conduit connecting the reservoir and brush pan, a

coverfor the pan. having 'a dipping basin provided with nonerforated sides and-n Y groupof small per orations in its bottom, substantially as described.

3. A cement pot, comprising, a brush pan having a cement chamber," a removable cover .therefor having a depressed dipping basin formed .with non-perforated sldes and a group of erforations in the bottom of said basin lea ing to the cement chamber, substantially as described.

In testimon whereof I aiix my signature, in presence o two witnesses. I
