UNITED STATES PATENT OFFICE.

M. H. MERRIAM AND E. L. NORTON, OF CHARLESTOWN, MASSACHUSETTS.

lNlPROVED GLUING AND CEMENTING MACHINE.

Specification forming part of Letters Patent No. 55,335, dated June 5, 1866.

To all whom it may concern:

Be it kllown that we, M. H. MERRIAM and E. L. NORTON, both of Charlestown, ill the county of Middlesex and State of Massachusetts, have invented all Improved Machine for Cementing or Gluing Shoe-Binding Strips; and we do herebyleclare that the following', taken ill collnection with the drawings which accoln pany and form part lof this specification, is a description of ollr invention sufficient to enable those skilled. in the art to practice it.

The invention relates to that one of the series of operations by which we convert skins of leather illto shoe-binding ribbon ill which the strips of leather are cemented together, one to the end of another, to form the ribbon.

More particlllarly this invention relates to the preparation and distribution of the cement ill such manner that it shall be exposed in a contilluolls and graduated fresh surface, to be applied by the operator to the end of the strip by simply wiping sllch end over the surface, obtaining` just and only sufficient cement by the manipulation to cause proper adhesion of the united surfaces.

The invention consists ill combining a at for holding glue or other celnellt with a cylinder rotating ill such vat (its lower surface be illg immersed ill the cement) and a scraper which removes the redundant cement froln the surface ofthe cylinder, leaving a tllill pellicle or surface of cement upon the cylillder, a portion of which sufficient for unitin'g the strips may be removed by passing the end of the strip across and ill contact with the rotatillg cylinder alld a colltilluously-fresh alld properlyprepared surface being always before the operator, ill consequence of the rotation of the roll in t'ne glue and the actioll of the scraper.`

The drawillgs represent a machine embodying the invention, Figure l showing a plan, Fig. 2 a central vertical and longitudinal section, Fig. 3 a central vertical and`cross section, alld Fig. et al1 end elevation, of the same.

a denotes a table or frame supporting a vat, b, the cement in which may be heated by steam passing around the sides and bottom of the same, or by any other suitable means. Mounted in bearings on the frame a is a shaft, c, carrying a cylinder, d, the shaft with its cylinder being rotated by any suitable power. The lower part ofl the cylinder extends down into the cenlellt contained in the vat. Upon one end of the vat is placed a scraper, e, the inner edge of which is nearly in contact with the surface of t-lle cylinder, and is moved up toward or away from such surface by an adjusting screw, j'.

The cement being brought by heat orother preparation to a suitable consistency, 'rotation is given to the cylinder, the scraper beillg adjusted to remove the redundant cement raised upon the surface of the cylinder. This being accomplished, the operator takes a strip of leather and wipes the end across the surface of coulent, obtaining upon it the proper qualitity of cement so disposed as to ilnpart the adhesiveness necessary to ullite the strip to another, tlle rotation of the cylinder ilnnlediatel y exposing a fresh surface of cclnent.

By this means it will be obvious that a perfectly uniform result may be attained ill llniting successive strips, there being always a fresh surface of cement so graduated in thickness as to obviate any liabilty of obtaining a supertluity of cement upon the strip.

When the celnent is applied to the strip it is removed to a press, ullder which another strip is already laid, alld the cemented elld is laid upon the elld in the press, after which a platen is brought dowll upon them lo hold tllenl together until the cement is set, a series of presses being used so that the operation ot' cementing may be carried on without stopping for the setting of the cement upon each strip.

We claim- The combination of the cement-containingvat, the rotating celnent-cylimler, and the scraper, operating together in the manner and for the purpose substantially as set forth.

In witness whereof we have hereunto set our hands this 24th day of November, A. D. 1865.

M. H. MERRIAM. E. L. NORTON.
