UNITEDy STATES PATENT QFFICE.

ISAAC F. YILLIAHS, OF NEV YORK, N. Y.

Specication forming part of Letters Patent No. 33,808, dated November 26, 186.1.

To @ZZ whom t may concern:

Be it known that I, IsAAc F. WILLIAMS, of the city, county, and State of New York, have invented certain vnew and useful improvements in machinery for applying docks, ground cork, or other similar substances to the surface of water-proof fabrics, for the purpose of making what is generally known in the trade as felt rubber goods, and I do hereby declare the following to be a full description of the same.

The nature of my improvements consists, first, in arranging the gumming-table at an inclination of about twenty-live degrees, in combination with a self-adjustable distributing-knife, so that when the solution of gum is applied to the surface of the fabric the knife-edge will cause it to flow evenly down- 4ward and laterally over the surface of the cloth to prepare it for the application of the flock; secondly, in combining with the revolving flock-duster and case surrounding it a smut-collector, so as to prevent the gummed surface of the cloth being smutched by the flock, which has a tendency to gather in masses at the front sides of the cluster-case and fall in iiakes upon the surface of the cloth and thus spot it, as well as to cause it to have an unevenness of surface unlike cloth-finished goods,which these goods are designed to represent; thirdly, in the improved construction of the iiock or cloth beaters, by combining with them swinging arms or beaters, so as to beat the under side of the cloth by a sudden blow to cause the flock to become more thoroughly set in the wet gum than can be done by fixed arms in the revolving beaters; fourthly, in the improved method of arranging the carrying-rollers of the cloth so as to suspend it while under the action of the beaters, and thereby prevent the cloth from jerking over the gumming-table and under the edge of the distributing-knife, and thus prevent its being evenly gummed over, and, fifthly, in combining with the beaters a finishing-brush.

To describe my invention more particularly, I will refer to the accompanying drawings, forming a part of this specifica-tion, the same letters of reference wherever they occur referring to like parts.

Figure l is a plan view of the machine.

Fig. 2 is a longitudinal out sect-ion through the line at, Fig. I. Fig. 3 is aside elevation of the machine.

Letter A is the frame of the machine, having transversely of the top of it a gummingtable B. This table is arranged at an inclination of some twenty to thirty degrees, so as to cause the solution of the gum, when applied to the cloth in passing over it, to spread more rapidly and evenly than would be the case if the table were level. Upon this table is secured a gum-distributer knife C, which rests on the surface of the cloth, and by means of set-screws c2 and a spring c3 on their lower ends is made so as to have a self-adj ustable pressure on the surface of the cloth while distributing the gum over it preparatory to the Hocking operation.

Letter D is a revolving Hock-sifter having an opening in its face for the introduction of the lflock and adj usted on suitable bearings d2 passing through the sides of a shell or inclosed case E surrounding it. In the front side of this case is cuta throat F, in which is arranged a sm ut-collector G, which exten ds into the case till nearly in contact with the sitter. The object of this arrangement is to collect the masses of flock, which have a tendency to accumulate in the front side of the case, and by falling upon the surface of the cloth as it enters the case causes a lumpy and smutched appearance, and thereby impairs the clothlike finish aimed at by the manufacture of this kind of goods.

AH H are two revolving beaters arranged on suitable bearings h2 in the lower portion of the sifter-case, so as to work at thelower side of the cloth to beat or drive the iiock into the Wet solution of gum on its upper surface. Attached to the periphery of the front beater is a swinging arm h3. The object of this is to give a more sudden blow than is possible by fixed or stationary beaters, and at the same time, in consequence of the swinging arm closing upon the face of the beater-axis, not jerking the cloth, as would be the case if the stationary beaters or arms were of the same diameter as the swinging arm is when distended. l

Letter I is a cloth carrying and supporting roller adjusted across the frame of the machine just behind the gum ming-table, and sol as to be slightly above tlie back edge of it. The object of this is to support the cloth and prevent the transmission of any drawing or jerking motion of it over the giinuniiig-table in consequence of the action of therevolving beaters.

Letter .I is a finishing-brush arranged in the back end of the sitter-case, the object of which is to lay the iiber of the iiock and give a smooth cloth-like finish to the goods.

K is a carrying-roller at the back end Y'of'- the machine, and L a revolving beater whose duty it is to beat off anysuperluous flock that may adhere to the gummed surface of the cloth. i'

Letter M is a cloth-roller secured at the front end of the machine in adjustable bearings m2,'having a balance-weight m3 attached to it by means of a cord running` over a pulley to equalize the pressure on the cloth as it increases or decreases in quantity on the roller.

Letter N is a carrying-roller, upon which the cloth-roller rests.

Letters P P are carryin grollers over which the cloth passes in going th rough the machine.

R is the cloth-beam arranged just under the gumming-table and off which the cloth unwinds in the operation of Hocking, dto.

Letters S S, &c., are a series of pulleys and belts for operating the several .parts of the machine, and T the piece of cloth, as represented by the blue-ink line.

proceed to set forth what MI claim and desire to secure by Letters Pat-ent of the United States y l. The arrangement of the gu mining-table so as to be an incline plane, as hereinbet'ore described, in combination with a self-adjust* able gum-distributer, for the purposes hereinbefore set forth.

2. The use of the throat F and smut-col*- lector G or equivalent devices in the sifter- -case as a method of preventing masses of falling flock from smutching the cloth, substantially as described.

3. The use of swinging arms or beaters h3, in combination with the revolving beaters l-I, substantially as described, and for the purposes hereinbefore set forth.

4. The use of the cloth-tension roller I, in combination with the carrying-roller K at the back end of the machine, arranged on a line below the revolving beaters, While the roller I is arranged on a line above the gummingtable, so as to support the cloth on these two points, and thus prevent the blows of the beaters drawing or jerking the cloth over the surface of the gumming-table.

5. The combination of the finishing-brush J with the revolving beaters, substantially as described.
