10 Claims.

This invention relates to a functionally and structurally improved applying machine. while a machine constructed in accordance with the teachings of the present invention is capable of use in numerous different associations, it is intended to be employed in applying cement or adhesive, and according to a more specific aspect of the invention it is a primary object to provide a cement applying machine intended for use in the manufacture of shoes and similar articles.

A further object of the invention is that of constructing a cement applying machine in which the application of cement may be controlled with that degree of nicety which is requisite to work of uniform quality, and to satisfactory mass production.

A further object of the invention is that of providing a machine of this character which may readily be manipulated and adjusted by the operator to conform to his own physical characteristics, and also to that of the work which is being performed.

A still further object is that of constructing an applying machine in which the parts are readily accessible for the purpose of cleaning, inspection, and adjustment.

An additional object is that of furnishing an' apparatus of this character, the parts of which will be relatively few in number and individually rugged in construction, these parts being capable of ready assemblage, to provide a unitary apparatus operating over long periods of. time with freedom from mechanical difficulty.

With these and otherobjects in mind, reference is had to the attached sheets of drawings illustrating one preferred embodiment of the invention, and in which- Fig. 1 is a fragmentary sectional side view of the upper portion of the applying machine, and taken along the lines 1-! and in the direction of the arrows as indicated in Fig. 2;

Fig. 2 is a partly sectional end view thereof;

Fig. 3 is a sectional view taken along the lines 3-3 and in the direction of the arrows as indicated in,Fig. 1; and

Fig. 4 is a fragmentary view of a type of base which may form a part of the machine.

As afore brought out, there is provided, by means of the present invention, an applying machine capable of main numerous different associations, but which is primarily intended in connection with the manufacture of shoes and similar products. Accordingly, in the following description and in the annexed drawings the in,-

vention has been illustrated in this preferred embodiment. This, however, is not to be taken in other than an illustrative sense except where restriction is indicated in the appended claims.

Thus, referring primarily to Fig. 4, it will be seen that the numeral 5 indicates a base upon which a motor 6 is preferably mounted. Positioned to one side of this motor, and conveniently integral with the base, an abutment 1 is provided. The machine proper terminates in the portion 8 straddling this abutment and is maintained in pivotal association therewith by means of a bolt 9. The motor has its power shaft enclosed in a housing II], which is extended, as at H, to accommodate a worm and worm wheel (not shown), the latter driving a shaft l2. This shaft is axially aligned with the bolt or pin 9, so that a swinging of the machine proper will in no wise affect or necessitatea rearrangement of the motor drive hereinafter described.

As afore brought out, the portion 8' serves merely as a mounting for the machine proper, and the latter includes a casing l3 providing a reservoir or container with which a cover it is detachably associated by, for example, bolts l5. Pivotally secured to the cover, as at I6, is an encasing or housing element ll, the latter being normally maintained against displacement from closed position as, for example, by bolts l8, which engage with screw threaded bores provided in abutments I9 forming a part of the main casting or body.

Disposed within the casing I3 is a body of liquid cement or other similar material, as indicated at 20, and partially immersed therein is a primary cement wheel 2|, mounted upon a rotatably supported shaft 22. The casing l3 may be formed with a depressed portion 23, providing a sediment trough, and a plug 24 may. bepositioned at this point so that the reservoir may be drained and cleaned. A shield 25 may be provided, and this element is mounted to ex-' tend in a substantially horizontal plane and above the body of fluid 20. The shield isformed with an opening or slot through which the upper portion of the Wheel 2| extends, and a wiping element 26 may be mounted upon this shield to lie in proximity to the periphery and adjacent surfaces of the wheel 2|.

justable towards and away from the Wheel by having its body formed with a slot through which a thumb-screw 21 extends. The latter. will, of course, be normally tightened so that the wiping element will be rigid with the shield, and

This wiping element" is preferably formed of fibre, and maybe ada spring 28 may also be provided to lie against the upper surface of the wiping element to prevent displacement of the latter.

Disposed above the primary wheel 2| is a secondary wheel 29, the latter being mounted upon a rotatably supported shaft 38, the distance between this shaft and the shaft 22 being such that the peripheries of the wheels clear one another by approximately one thirty-second of an inch. This spacing may, of course, be varied according to the viscosity of the fluid which is employed, as well as the character of work which is being undertaken, but in any event it will be appreciated that by this construction a certain amount of fluid adheres to the adjacent surface of wheel 2i and is transferred from the latter to the periphery of wheel 29.

Adjacent its forward edge the casing l3 may be thickened, to provide a sleeve portion 3i, to rotatably enclose a shaft 32. At the upper end of this sleeve portion there is positioned a cement brush, preferably including a body 33 of rubber or similar material, which is disposed upon a flanged disk 34 and retained in position thereon by a clamping plate 35. The shaft 32 is preferably supported by a thrust bearing which includes, in the present exemplification, a sphere 36 having its surfaces inv contact with concave recesses formed respectively in the end of the shaft 32 and in the end of a screw 3']. The latter has its head extending below the thickened portion and may at this point conveniently mount a lock-nut 38. Consequently, it will be understood that by means of the screw 31 adjustment may be readily made which will prevent undue play on the part of the shaft 32 and will also permit of the latter being caused to assume any proper position. The connection between the brush head and this shaft preferably embraces a projecting portion or stud 39, which forms a part of the head, and a notch or slot which forms a part of the shaft. Consequently, while the head may readily be removed from or coupled with the shaft, these parts will normally rotate as .a unit. With final reference to this portion of the mechanism, it will be observed that in order to prevent upward movement on the part of the applying roll or brush, the housing element I? may be extended, as has been indicated at 40, and a pivot screw 4| may be mounted by this extended portion in axial alignment with the shaft 32. Thus, the head or applying roll, while free to rotate, cannot be accidentally displaced, but by simply lifting the housing I! it is entirely practical to remove this member as a unit. Additionally, it will be noted that by this extended portion there is provided, in cooperation with the thickened portion 3|, an encasing member which will act as a protecting guard for the applying roll.

With a View to providing a drive for this mechanism, it will be noted that the driven shaft l2, extending from the motor, carries a sprocket gear 42, which serves to drive a chain 43 passing around a sprocket 44. The latter is mounted upon a shaft 45, carrying a sprocket 46, in turn coupled through a chain 41 to a sprocket 4B. This sprocket serves to rotate gears 49, 54), and 5|, the former being secured to shaft 22 and the latter being coupled to shaft 33. The shaft 45 also carries a bevel gear 52 meshing with a similar gear 53 which, by means of a key or otherwise, is coupled to the shaft 32. Consequently, as the shaft 45 is driven, the shaft 32, together with the applying roll, will be rotated.

In conclusion, it will be noted that there is preferably associated with the applying roll a wiper 54 which may be formed of fibre, and cooperates with the periphery and adjacent surfaces of the roll. While any desired form of mounting may be utilized, it is preferred that it be secured to a screw-threaded stem 55, with which a knurled nut 56 cooperates, and a spring 5'! normally tends to project the wiper into contact with the surface of the roll.

Assuming that the parts are disposed in the manner before described, and that the reservoir is filled to a proper depth with cement or other desired fluid, it will be appreciated that, with the motor operating, both the wheels 2| and 29 will be rotated (in counter-clockwise directions). Surplus fluid will be removed from the wheel 2! due to the provision of the wiper 26, it being thus possible to accurately adjust the thickness of fluid film adhering to the surface of this roll or wheel. At their points of greatest proximity-and incident to the relatively minute spacing of the wheels-the fluid is transferred to the wheel 29, it being, of course, appreciated that the latter, in effect, has only its periphery coated, for the reason that no splash may be transmitted past the .2

shield, and also incident to the fact that the wheels have only their peripheral portions in cooperative relationship. The thin film of liquid is carried to the applying roll or brush, and the latter is revolved so as to receive an even coating of fluid and to distribute the same at a point at which the operator may bring surfaces to be coated in contact with the same. Again, before this point is reached, the thickness of fluid film upon the brush may be adjusted incident to the provision of wiper 54, and it will thus be appreciated that, in this manner, it is possible to accurately adjust the parts so that the desired amount of cement or other fluid is delivered.

Of course, in lieu of the various drives which have been illustrated, any desired form of impelling mechanism might be substituted, but it will be noted that, regardless of this mechanism, a construction is provided which permits of instantaneous accessibility to all parts. the fact that the shafts 22 and 30 are preferably vertically off-set, and also due to the fact that the body of the applying roll or brush extends normally at an angle of approximately thirty degrees to the horizontal, the operator may at all times secure a clear view of his work and thus perform his task with maximum elficiency. If, however, for any desired reason, it is necessary to change this angle, this may readily be achieved by simply loosening the bolt 9 or its equivalent and inclining the housing as may be desired, within practical limits.

Thus, among others, the several objects of the invention as specifically afore noted are achieved. It will be understood that numerous changes in construction and rearrangements of the parts might be resorted to, without departing from the spirit of the invention as defined by the claims.
