2 Claims. 5 (01. 91-456) I "This'invention' relatesto cement pots and particularly to cement pots which have been designed for use when cementingjsoles to shoe bottoms; The device is "sp'ecially advantageous. for

ing soles to. theshoe bottom, but it is also useful in shoe manufacturing establishments in which shoes are being manufactured with the soles cemerited thereto.

Incementing a sole mentfis applied to the shoe bottom .and alsoto the attaching face of the sole. Thecement is f requentlyhpplied to the sole: when the latter is made and sometime prior to its attachment to the shoe. In such case it is necessary to apply a solvent orsoftener to the cemented ia'ce of the sole when the latter is to be attachedto the shoe in order to give the sole a proper adhesive sur face, "and in order to do a good job in cementing I a sole to ashoe it is importantthat' the correct amount of solvent or softener should be applied tothe sole. 7 In repairing'a shoe by resoling it, it

is also 'importantfthat'the right amountof ce-- m'ent shouldbe 'appliedto the shoe bottom before the sole is-Qattached. If anli 'sufficient amount of cementis applied to the shoe bottom the sole will not adhereproperly 'tothe, shoe and it is liable to peel oil as the shoeis worn. If too much cement is applied to the shoe bottom the surplus l cement is liable to be squeezed outfrombetween the sole and the shoe bottom whenjjthe pressure is applied to the'sol'e, and the presence of such surpluscement is a source of arinoyantzaridhos- Sible detriment. I r

In repairing shoes the cement is usually. applied to the shoe bottom through the medium of a brush and the solvent or softener for softening the cement with which the attaching face of the sole has been provided is also"usually applied with a brush and, as stated above, the excellence of a 'job of resoling a shoe'depends to a considerable extent upon using the correct amount of softener for solvent and the correct.

used .for applying the cement fto the 'bottom'of'a amount of cement. V Thecement is usually applied around the marginal portion of the shoe bottom and the solvent is also applied around the marginalportion of the sole so thatwhen the sole iscemented to the shoe the adhesive attachment is at the marginal portions of theshoe. The cement and the solvent which is used, by cobblers is usually put up in tins and theipresent'method isifor the cob- I bler to pour out the cementand the solvent into separate dishes and'the'n to .dipfthe brush into these dishesandapply the cement and the solvent to the Shoe bottom an'd'the sole respectively. With this method the amount of cement and solvent which is used on any shoe dependsupon the judgment of the operator.

.One object of the present invention is to proshoe a coating of cc- I tached'to the pouringjopeningfot thece'ment:

each time the-latter is dipped into; the cement p vide a novel cement pot device which' may be at and thislamount will preferably'be such that one brushful'o'f cement will provide the required I amount of cement foriiseon one'shoe. The same device is also applicable foruapplyin fthe ,sol-

Sole-or shoe bottomand thus put bothin .eonldition for the cementing operation. In, order to give I an understan scribed after which: the novel features will be pointed out in" the appended claims.

'Thistin can 'is shown as having the screw threaded neck 2" which provides a pouringflopening and which is adapted to be closedbya plug or closure B-that is screw threaded into the-neck.

I The improved comprises a member 4 made of metal-or'anyother; suitable material which is to rest on the table, floor or other support-J'I'heformed with cementreceiving chamber fi and with a suitable base" 60 cement pot herein illustrated of a size to receiveabrush 8.1811011. as is commonly with a laterally-extending nipple 10 having an;

opening v11 therethrough which communicates f with the cement-receiving chamber 5. N This nip;v

pie is formed at its extremity to permitit'jtobe attached to the neck-2 of the can '1- Where the neck is screw threaded as herein shown the e otthe nipple 10 will have the exteriorly screw: threaded portion'12 of the proper size and conv screw intothe neck .2 as shown in struction to Fig. 4, a gasket or v washer 13 preferably being employed to make a tight joint and prevent leak vent so that the correct amount oi solvent may I102 from andwhich is of sufiicient size to form a cover tween them nd when the flange has been placed ment. The size of the brush and the construcage around the screw threads when; the device is i used..

The position of? the nipplelO with reference'to the base 6 issuch that when said nipple has been screw threaded into the neck 2' the base 6 stands substantially flush with the side .wall 14 .of the can. r r In using the device the plug 3 is rmovearmm' the can and the member 4 is screwed into the neck 2. V The can may then be laid on its side as shown in Fig. 4 and this will allow the contents of the can to flow through the'nipple 10 into 1 c f the chamber 5- When theilevel of; the liquid in the chamber 5 rises above the opening 10 any further discharge of the contents of thecan into g the chamber 5 will cease because the j liquid in the chamber 5w'ill-prevent the admission of air into the can 1.

I The brush 8 is'provided with meansffor supporting it on the upper. edge of the inember4 in such a position that the bristles thereoffwillbe partially submergedin the liquid in the well or chambjer 5. The meansherein'shown for this purpose comprises a flange 15 rigid with the ham dle of the brush and extending-laterally there'-' for the-open end 7 of the chamber 5. "In fact,

if desired, this flange portion 15 'may be cone structed so that itwill make a sealed cover. The flange herein shownis provided wtih a depending skirt-16 whichencircles the'topof theimember 4 and it is also provided withinturned ups 1r: which" are setata slight angle-and which are adapted to engage underneathprojections 18 with which the top of the member 4 is provided. 19 indicates a gasket or packing washer inside j of-the cap-l5 which; engages the top edgeofsthe member 4. r v

fv'l'he spacing between the lugsor projections 18 is-suli'icien't to permit the lips 17 to pass bein position with the gasket 19 in engagementwith the -top edgeo'f the member 4' a slight turning movement will operate to clamp the r V cap 2 to the member-4 because of thein'clination of the lips 17; With-this construction the level ofthe'liquid in fthe-chamber 5 will bekeptapproximately i'sQs'ho'whiri Fig."4.- l Since the level of the liquid inthechamber sible' to dip the brush deeper into the liquid'than 5 ismaintained at' a'ccnstant point and sincethe brush can be dipped into the liquidonly to the extent determined by the flange orcover l5 zit willfollow that each time the brush is withdrawn from the; chamber. 5 it will .carry' the; same amount of liquid. {As the liquid in the chamberi5 is used and theliquid leveljis'low-. ered sufficiently toadmit air into the can 1 through the passage 11 then there will be atransfer. of liquid from the-can into the chamber '5- suflic'ient' to again choke the passage 11. and stop -f '1. 1rther flow sothat, as stated above, the liquid levellin the chamber 5 will be maintained ,sub-

Hence with this invention a definite, amount of liquid, whether it be cement or solvent, can be securedby simply dip-w ping the'brush into the chamber 5 as far, as the flange .15 will, permit and then withdrawing the brush andb-the dan'geroi too scant or, too liberal.
