cEiviENTINGV APPARATUS.

' Patented April 28, i908.

-To all whom it may concern.'

Be it known that we, CHARLES WILLIAM PHIPPs, trading as PHIPPs & SON, merchants and manufacturers, and WILLIAM JOHN STEELE, engineer, both subjects of the King of Great Britain, citizens of Northampton, England, residing at Guildhall Road, Northampton, England, have invented new and vuseful Improvements in Cementing Apparatus, of which the following is af speciiication.

This invention relates to apparatus for containing cement, adhesive or the like and is particularly, though not exclusively, applicable to the type of cementing machine employed in coating with cement the edges of material, such for example as sections of the uppers of boots and shoes to unitel them temporarily preparatory to their being permanently connected together in a sewing machine. Machines of this character have heretofore comprised in their construction a vessel or receptacle to contain the main supply or stock of cement, a closable opening through which the vessel is iilled, a trough having a duct communicating with the main receptacle and for containing a small quantity of the cement for immediatefuse and a shutter to close the trough or its duct so that the cement, which may be of a highly inflammable nature, may not remain exposed when not in actual use.

The present invention relates to an improvend construction of machine comprising a main vessel or stock receptacle, a feed opening or inlet therein, a slidable door thereto having a locking device, such for example as a spring controlled pin or bolt and lever, to lock the said door in its closed position and secure the cement against exposure to the atmosphere, and means, such for example as a cam lever, to withdraw or slide the door or lid away from the feed inlet of the vessel or cement pot.

The invention also comprises a valve which automatically closes and opens the duct leading from the receptacle to vthe vtrough synchronously with the opening and closing respectively of the. feed opening. While the valve and duct are open the cement will be maintained at a uniform height in the trough, but when the sliding door of the feed opening is withdrawn it is advisable to close the said duct to prevent a rush 'of cement into the trough and an overiiow of the latter. When however it is only desired to replenish the trough by allowing cement to flow through the duct into the latter, or to cut off the communication between the trough and the main supply in the receptacle,

the locking device of the sliding door is not released, and the cam lever is given a sufficient amount of movement to operate the valve rod and valve to open or close the said duct. The cement may be taken from this trough by a brush and the operator may paint or coat the edges of the upper sections with it in the well understood mamier. In order however to effect this operation i. e. coating the edge of the upper section, mechanically and automatically, as far as we are aware for the first time, a roller may be revolubly located and dip in this trough so that when the edge of the upper section is passed thereover it will take up the cement from the surface of the roller and become coated thereby and'at the same time will by frictional contact simultaneously rotate the roller in the trough so as to bring a fresh surface of the roller to the next upper'section.

A ressure device referably in the form of a rol er may be emp oyed to press the upper section on to the coatin roller. Such pressure roller is normally ield out of contact with the coating roller by a spring or equivalent means so as to keep it clean and prevent it coating the op osite edge of the upper section as it would o if both rollers were in surface contact. The coating roller may also if desired be ositively driven through the medium of suitable mechanism such for example as gear wheels, a driving shaft and belt pulley thereon.

When it is desired to coat both sides or edges of the uppersection or other fabric with cement the pressure roller and the coating roller are allowed to be permanently in1 surface contact.

The invention will be further described in detail and reference made to the accompanying drawings wherein Figure 1 is a front elevation of a cementing a paratus constructed in accordance with t iis invention. Fig. 2 is aK longitudinal section of the apparatus and Fig. 3 is a plan of same. Figsf and 5 are plans of the main parts of the apparatus and show the slidable door in its closed and open positions respectively.

Like reference characters are employed to designate the same parts in all the figures.

In a machine'constructed according to the present invention 1 represents a main vessel or stock receptacle furnished at its up er end with a slidable lid or door 2 having a ocking 5 device to lock it in its closed position. A

convenient construction of locking device comprises a spring controlled bolt 3 carried in a hxed bracket it and operated vertically therein to unlock the lid by depressing one end of a lever 5 pivoted to said bracket as shown in Figs. 2 and rllhe stock vessel 1 has a feed inlet or illing opening (i therein and when the latter is covered and closed by the slidable doei' 2, as shown in Figs. 1 to 4;,

the locking bolt 3 under the influence of its s ring bears with pressure upon and forces tlie said door 2 down air-tightly upon a joint ring 7 of rubber or equivalent material arranged around the feed inlet and thus secures the cement against exposure to the atmosphere.

rllhe slidable door or lid 2 may be withdrawn from over the feed opening 6 of the stock vessel for iilling purposes by means of `a cam lever S the latter (after the bolt 3 is lifted fioni the doei' 2 by depressing the free end of the lever 5), slides the said door to the withdrawn position shown in Fig. 5.

The front lower portion of the stock receptacle 1 is furnished with a trough 9 and a -duct 10 communicates between the said trough and the interior of the stock receptacle, to permit cement to flow into the trough. A convenient construction of valve for con- `trolling the flow of the cement through the nected to the cam lever 8 and is operated thereby. The lower end of the rod 11 is provided with a diainetrical hole forming a valve 12 so arranged that it may be moved into ahneinent or register with the duct 1() and thereby forni a through passage for the cement to flow into the trough from the stock vessel, as shown in Figs. 2 and 3; upon the said rod being partly rotated it will close the said duct 10 by bringing a solid or unperforated portion of the rod 11 opposite thereto as shown in Figs. 4 and 5, and thus stop the cement feeding to the trough.

The cam lever 8 is attached. to the valve rod 11 in such a position that when the said lever is moved to withdraw the door and nncover the feed opening 6 the rod will be synchronously turned thereby to the position to close the duct- 10, as shown in Fig. 5, and vice versa. This simultaneous action of opening the door and closing the duct will only be necessary when it is desired to re-iill the stock receptacle. Then however it is required to open the valve to replenish the trough 9 only, by allowing cement to flow thereinto through the duct' 10, or to cut off stop pin 14, Figs. 3 to 5, and it will be noticed, by reference to the last named ligure, that owing to the particular positions of the lever S and valve or hole 12 on and in the rod 11 it is impossible to open the feed inlet and door 2 without first closing the duct lt). For the purpose of mechanically and automatically coating the. edge of a boot upper section or similar goods the machine is furnished with a roller 15 revolubly located in the trough Sl so that its lower part constantly dips in the cement. Then the said roller is rotated by the passing thereover of an upper section o1' by positive driving means, as hereinafter described, it will take up the cement and thereby coat the goods placed in contact therewith.

pressure roller 1o is carried on a. pivotedI lever 17 Fig. l the said roller being normally held out of contact with the coating roller 1:1 by a spring 1S Figs. 1 & 2%.

The pivoted lever 17 of the pressure roller 1G is connected b v means of a chain 1t) to a foot pedal or knee lever (not shown) so that when either of the latter is actuated it will lower the. pressure roller 1 on to the u ppersection or other work and press it into positive contact with the coating roller, to receive a coating of cement'. therefrom. 'llhe surface of the latter roller may be milled or serrated and the lowering of the. pressure roller 1U by the operators foot or knee leaves both his hands free to manipulate the work passing between the rollers.

Mechanism may be arranged to positively drive or revolve the coating roller 15 and this mechanism according to one arrangement may consist of a driving shaft 2t) actuated by bevel wheels 21 from a belt pulley 22 the said i'oller being driven `from the shaft 2() b v intermediate gear wheels 23 Figs. 1 and 2.

Then it is desired to coat each of the two opposite sides or edges of the upper section or other fabric with cement the pressure roller 1G and coating roller 15 are allowed to be permanently in surface contact so that the cement will be taken up by the coating roller and transferred thereby to the top or pressure roller.

Then no coating or pressure rollers are employed the operator removes the cement from the trough by a brush and applies it to the material in the well known manner. Then however the coating roller or rollers is or are employed the cement is allowed to flow continuously through the duct 10 into the trough while the machine is 1n use. The most important feature however of the invention is the arrangement by which` the valve which controls the supply of cement to the trough, and the o ening and closing of the door over the feed mlet are controller by the same lever 8 the latter being so arranged that when moved in one direction (shown by the arrow) to the limit of the cam slot it ro'- tates the rod l1 and removes the hole 12 therein away from and out of register with said duct so that the valve and duct are closed and the flow of cement to the trough is stopped. The lever, if its movement is continued Will by ressing against the pin on the door 2 slide t e latter along and withdraw it from over the feed opening 6 to permit of the stock vessel being re-filled. It will be obvious therefore from the foregoing description7 that the movement of the lever 8 within the limit of the slot in one direction will open the valve and duct so that cement may flow into and replenish the trough and the movement of the said lever 'within the linit of the slot in the opposite direction will and duct are closed the lever slides the door` away from and exposes the feed inlet. The said lever therefore with a limited movement in opposite directions opens and closes respectively the valve and duct and with a further and continued movement in the same directions closes the said valve and duct and stock receptacle, a .trough communicating therewith, a feed opening to the said receptacle, a door, and a cam lever to actuate the said door to close and open respectively the said feed opening.
