CEIMENTING MACHINE.

Application filed April 22, 1920. Serial No. 375,834.

T 0 all whom it may concern:

Be it known that I, WILLIAM F. LAUTEN- SGHLAGER, a citizen of the United States, and residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Cementing Machines, of which the following specification is a full disclosure.

My invention relates to cement-applying machines, primarily applying a coating of cement along the margin of material. The material at its margin is drawn across a revolving cement-applying brush.

In machines of this class, the revolving cement brush receives a supply of cement continuously from a revolving cell-faced or corrugated cement distributing roll, mounted at the end of a supply passage or feeding head, connecting with a cement pot or reservoir. The distributing roll and brush rotate in a clockwise direction, thus moving at their point of contact in a direction counter or opposite to each other. It has been the general practice to mount the distributing roll below the feeding head or passage connecting with the cement pot or reservoir and engaged into a cylindrical recess in the base of the head, as a sleeve or cylinder valve, so that the head on one side of the roll provided a feeding spout contacting with the periphery of the roll for preventing the feeding of excess cement to the periphery of the roll or an amount greater than would be carried by the cells in the face of the roll. The head of the opposite or return side of the roll is arranged to provide a mouth to receive any excess cement carried upon the periphery of the roll and lead the same back into the feeding head. The excess cement on the return side of the roll instead of being drawn or carried back into the cement feeding head after a few roll revolutions accumulated upon the periphery of the roll between the incoming end of the feeding head and brush in such proportion as would materially interfere with the use of the machine.

The commercial field for the machine is largely in shoe factories for applying cement containing volatile ingredients, which, when exposed to the atmosphere evaporates readily, allowing the cement to congeal or coagulate when allowed to accumulate upon the periphery of the distributing roll, especially when having a thick grade of cement.

The light or thin grades in volume do not: and thus drop withholds any return of the surplus cement carried upon the roll into the head. The cement will ooze and permeate through the return opening in the-head and add to the increasing accumulation on the return side of the roll. Such accumulation is further augmented by the relative opposite directions of the distributing roll and brush rotation at their point of contact, and differential rate of speed, the roll rotating at a lower rate functions. as a wiper for the brush instead of a distribution.

It is therefore, an object of the invention to arrange the parts relatively to overcome the above stated objections, and provide a machine which may be run continuously with the cement distributing roll, delivering a well regulated uniform supply of cement to the brush, in which no roll wiper or clean ing is required while the machine is being continually operated.

Another object of the invention is to arrange the cement supplying head at one side of the rotary" cement distributing roll which coacts with the mouth of the head to bring the outlet point or line of the feeding head in close proximity to the point of contact of the cement applying brush with the distributing roll.

Another object of the invention is to utilize a rotary liquid cement distributing roll as a valve for closing a cement sup'portport or opening, the valve being of a cylindrical dimension to bear against a semi-cylindrical seat surface extending above the opening-to bring the height of the end of the joint between the contacting valve and seat surfaces to an'elevation which will prevent seepage or permeation of cement upwardly there-- through.

The cement usually used in the manufacture is of a character having a rubber foundation or base, known to the trade as rubher cement, and various grades, kinds and 1 drawings colors are used for different classes and character of material. Under the prevailing practice a separate machine is required for each grade of cement, otherwise the reservoir of the machine has to be drained and the parts thoroughly cleansed in chang ing from one grade or kind of cement to another. lVith' my improved machine the change can be readily and conveniently made by substituting one cement distribut ing unit for another, with the roll, supply head,and pot or reservoir as a distributing unit detachable from the machine, which feature provides a further object of the invention, and in providing the machine with a plurality of distributing units one for each of the different grades or kinds of cement required.

With the foregoing, and other objects in view, which more fully appear in the following description of the accompanying drawings, forming a part of this specification, like characters of reference in the denote corresponding parts throughout the several views, of which Figure 1, is a side elevation of my improved cement machines which maybe mounted upon an standable table or bench.

Figure 2, is an end elevation thereof with a portion of the cement pot and supplying head shown in section.

Figure 3, is a detail top plan view of the cement distributing roll and its valve controlled cement supply passage within the end of which the roll is journaled.

Figure 4, is a vertical section on line 1-4L Figure 2.

Figure 5, 1s a section taken on line 5-5 Figure 4, illustrating the means employed for detachably connecting the distributing roll with its driving shaft.

Many of the detail parts of the machine in construction compare similarly, and are standard with like parts of cement applying machines shown in prior patents issued to me April 24, 1917, No. 1,228302, and No. 1,223,403, and the machine herein shown and described is also applicable for practicing the method of cementing the margins of flexible material disclosed in a prior patent. issued to me April 24, 1917, No. 1,223,404, so that no further elaboration as to the use and purposes of the machine for the various kinds of work particularly contemplated need be included herein. Reference to the aforesaid patents being had for such purposes.

The frame of the machine in its preferred form comprises a column 1, extending upwardly from the base, which is arranged to be secured to'a suitable support or table. The column 1, has an overhanging arm 2, and a downwardly extending bearing extension 3, for supporting the transmission elements and cement applying instrumentalities sutliciently free from the column so that the operator has full and convenient access to the cement applying brush, and the work can be freely passed or wiped across the brush for applying a coating of cement.

The rotary cement applying brush l, is of circular form with its bristles radiating from the axis of a specially built-ug type found most etficient for cementing the margins of flexible material used in the manu: facture. of shoes. The brush is divided into annular rows separated by rings or disks,

loosely mounted upon the hub 5 of the brush.

The. hub is provided with an angular flange at one end of the brush and guard plate 6, of particular shape, at the opposite end of the brush. This guard plate is loosely mounted upon the, hub of the brush and will be more fully described in detail hereafter. The

plate is the duplicate of the cement control-.

ling device orplate shown and described in the above-named prior patents. The hub of the brush is removably keyed or pinned upon the end of the main driving shaft 7, journaled in bearings in the column 1,.and

bearing extensions 3. The shaftis provided I with a pin 8, engaged through the shaft and into open end notches9, milled, into the end of the hub. This adapts the hub to be readily slipped on and off of the shaft when the screw 10, threaded into the end of the shaft has been removed. The shaft 7, is driven by r a pulley 11, fixed on the end of the shaft. A second shaft 12, journaled in bearings in the column 1, and bearing extension 3, extends to provide a cellular surface, as cement conveying pockets 17, for conveying the cement from a cement passage or chamber to the brush.

The cement distributing roll, as shown in section Fig. 4t, is fixed upon a sleeve 18, and

the sleeve concentrically engages upon the end of the shaft 12. The sleeve 18 has a pin 19 engaged and secured transversely through? one end engaging into a transverse slot milled into the end of the shaft for removablv keying or connecting the roll to the shaft- Hub plates 20, 20 engaged. concentrically upon sleeve 18,'at opposite sides I of the cement distributing roll, provide means for rotatively mounting the roll and its sleeve upon the. end of the cement feeding head 21. The cement feeding or conveying head may be described as an L-pipe fitting Or conduit providing a horizontal cement passage, for conveying the cement to the periphery of the distributing roll'or as a cement supply or chamber, within which the roll revolves for taking up a supply of roll receiving 22 projects upwardly and forwardly from the feeding end of the head and over the roll and its lower or interior face recessed be tween the sides of the roll, as shown at '23, Fig. 4, to provide a cement'rc'ceiving throat or mouth at an elevation above the supply chamber of the cement supply head, through which any surplus cement carried upon the periphery of the roll may be carried therewith into the cement supply chamber. The lip presents an increased roll overlapping bearing surface on, the descending or seat bearing side of the roll periphery according to the direction of roll rotation, so that an efficient seal against any escape of cement when the roll is stationary, eliminating objections heretofore encountered in cementing machines of this class. The outlet Or discharge throat between the end of the supply and periphery of the roll is brought at a lowermost point or elevation of the supply chamber, immediately adjacent the cemcnt ap lying brush, so that any cement escaping t rough said discharge threat is deposited directly upon the brush and is carried forward by the brush, while the brush is rotating. The brush is rotated in a direction from the throat and forwardly with the roll at the point of brush contact with the roll, so that there is no possible wiping or scraping action between the cooperating parts, to permit an accumulation of cement. This construction and coordinate direction of the roll and brush rotation, within a cement supplying zone of the parts, renders possible the distribution of a continuous, regulated and uniform supply to the brush, when the parts are in operation, without the liability of surplus cement accumulation.

The cement supply head has a threaded end for connecting the shank or nipple end 24, of the cement pot 25, and the supply from the pot to the supply chamber of the head is controlled by a plug valve engaged into and through the head, and thereby forms a part of the head. The pot 25, at its lower spherical face, is provided with a pro jection lug 26, adapted to rest upon an arm 27, extending laterally from the free end of the overhanging arm of the pedestal. The arm 27 is notched to receive a pin 29 projecting from the lug for locking the pot and cement supply head or unit in a properly installed position upon the pedestal and renders the same easily removable. vTo remove,

the cement supply unit of-the pot supply head and distributingIroll, it is-swung lip-- wardly about the axis of the drive shaft 12,

releasing the pin or locking engagement with the pot supporting arm, and-'when in such upward position the unit is slid endwise from the end of the shaft 12.

This enables an easy and quick substitution of one cement supply unit for another when a change fromone grade or quality of cement to another is desired. In utilizinga plurality of cem'ent'supply units for the various kinds of cement, capable of being interchangeably installed upon the machine, no time is consumed in making the change from one kind of cement-to another, and the cement may be stored in the units until en tirely consumed, which resultsrin quite a saving over the older methods, in whichthe supply head and pot were drained and flushed for eachchan'ge. The cement pot is provided with the-usual strainer 30 and sealing cap 31. I

In the guard plate 6'the construction 1s substantially the same as the cement controldevice shown in my prior Patent No. 1,233,403, heretofore mentioned, mounted about the axis of rotation of the brush. The

plate, in the form shown, is provided With a. central or middle disk portion which contacts with the hub of the brush for preventing seeping of cement to the brush shaft and i held upon the shaft by the screw 10. In order to prevent rotation of the plate with the shaft and brush, it is provided with a tail piece 34 arranged to contact the cement applying head, and thus limit its rotative movement about the shaft in one direction and permitting a movement about the shaft m an opposite direction if such should be desired for cleaning purposes. The plate is provided with a lateral sloping lip 35, and a second peculiarly formed lip 36 opposite from the lip 35, the purpose and function of which is fully described in the specification of the aforesaid Letters Patent.

A guide arm 37 fixed to the depending bearing extension 3 of the column or pedestal, is provided at the opposite side of the brush from that of the plate 6 against which the material to be cemented is engaged for properly guiding the work across the brush. The plate 6 as a guide, may however, be variously modified or eliminated as occasion may require, the same being incidental as apart of machine and not particularly essential to or concerned with this invention.
