LATEX APPLYING MACHINE Filed Sept. 14. 1928 INVENTOR WEHJZym AONEY.

Patented May stars HERBERT R. POLLEYS, 015 NEW HAVEN, CONNECTICUT, ASSIGNOR TQ NATIQNAL INDIA. RUBBER COMPANY, OE BRISTGL, RHODE ISLAND, A. COR-PORBLTION OF CONNECTICUT LATEX APPLYING MACHINE Application filed September 14, 1928. Serial No. 305,998.

This invention relates to a machine for applying liquids having low viscosity or low specific gravity, such as water dispersions of rubber, for example latex, and also light cements, to the surface of an article of foot- Wear.

This invention is an improvement upon the machine disclosed in my co-pending ap-' plication, Serial No. 279,040, filed May 19, 1928 for a cement applying machine.

The machine disclosed in my previously filed case above referred to is best adapted to the application of viscous cements of a high specific gravity and does not efficiently applythe lighter and less viscous liquid, such as latex or light cements.

It is an object of the present invention to improve the machine disclosed in the above mentioned application so as to adapt it to the application of light cements and latex.

A clear understanding of the invention may be had from the following detailed description and accompanying drawings in which:

Fig. 1 is a detail perspective view of a portion of my improved machine, and

Fig. 2 is a detail perspective view of the mechanism shown in Fig. 1 with parts removed.

The liquid to be applied, such as a water dispersion of rubber, for example latex, or a light cement, is fed from a container through a pipe connection (not shown), into the inlet 1 integral with the cover plate 2 which is hingedly mounted upon the case 3. Bolt 4: and thumb nut 5 serve to secure the cover plate 2 in position on the casing 3. A'disc 6 is rotatably mounted in the casing 3 in the manner shown in my above mentioned application and has a portion thereof extending from the casing 3,

The cement flowin through the inlet 1 iiows over the top 0 the disc, around the edge thereof and down into a slot 7 (Fig. 2) in the casing 3. A spillway 8 is mounted upon the front edge of the casing 3 in register with the slot 7. Scraper plates 9, 10 and 11 are arranged about the front edge of the casing-and cover plate so as to prevent the escape of the liquid from the casing at any point other than through the channel 7,

A table plate 12 with brushes 13 and 14 mounted in a manner such as disclosed in my above referred to application, is juxtaposed to the casing 3 and disc 6. When an article of footwear, such as a shoe, is moved sole down along the table and the upper thereof brought into contact with the edge of rotating disc 6, the cement flowing from the spillway 8 and runnin along the edge of the disc 6 will be applied to the upper of the shoe, the'brushes l3 and 14,- serving to brush the cement or latex onto the upper of the shoe and over the bottom thereof, the brushes being supplied from the overflow of the spillway 8. The distance between the table 12 and disc 6 is such that when the shoe is moved in an upright position over the surface of the table, a foxlng or a coat of adhesive of the proper width will be formed thereon,

By the use of the spillway 8, my machine,

otherwise as disclosed in the application above referred to, may be used to apply latex or other water dispersions of rubber and compounding ingredients or light cements to footwear or other articles, a result which heretofore has not been efliciently attained by other cement applying ma chines.

While one specific embodiment of my in vention has been disclosed herein, the improvement which I have invented may take other forms, such as will occur to one skilled in the art, and for an understanding of the scope of my invention reference-should be had to the following claims.

Having thus described my invention, what I claim and desire to protect by Letters Patentis:

1. In a machine for applying a liquid material to footwear in combination, a rotatable disc for applying a head of liquid material to a shoe upper, and means for supplying such liquid material to the disc and the shoe upper at a point adjacent the point of application.

2. In a machine for applying li uid material to footwear, a rotatable d1sc or applying a head of liquid material to a shoe upsupplying cement at the per, and a spillway adjacent said disc for oint of application near the edge of and lmeneath the disc.

3. In a machine for applyin liquid material to footwear, a casing, a d1sc rotatably mounted in said casing and extending therefrom, a channel in said casing adjacent said disc to permit the passage of liquid'material, and a spillway attached to said casing in register with said channel, said spillway being arranged to conduct the cement to the point of application to footwear at the edge of the disc.

4. In a machine for applying liquid material to footwear, a rotatable disc, means for wetting the margin of the disc with liguid material and for supplyin it freely jacent the point of contact 0 the disc with the article of footwear, and means for brushingiliquid material on to the bottom and side ofthe article of footwear.

Signed at New Haven, county of New Haven, State of Connecticut, this 11th day of September, 1928.

HERBERT R. -POLLEYS.
