METHOD OF FORMING LATH BOARD.
APPLICATION FILED SEPT. 11. I917.
Patented Feb. 4, 1919.
f/vz/e/wor d/ha M Fora UNITED STATES PATENT OFFICE.
SILAS M. FORD, 015 ST. PAUL, MINNESOTA.
METHOD or romaine LATE-BOARD;
, To all whom it may concern:
Be it known that I, SILAS M. Form, a citizen of the United States, and a I'GSlClBIlt'Of St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Methods of traveling forming means, cooled while in the forming means, and passed from the forming means with the'corrugations set in the cooled paper.
With these and incidental objects in view the invention comprises certain sequences of operations, the essential requirements of which are shown in the appended specification and drawing.
The drawing shows in side elevation a conventional form of a machine which may be employed in carrying out my improved metho J ournaled 'on the frame 1 a, pair of shafts 2 and3 carry sprocket wheels 4 and 5 respectively, and a sprocket chain 6 is carried by these sprocket wheels.
A second set of shafts 7 and 8, likewise journaled on the frame, carries sprocket wheels 9 and 10 which in turn carry a sprocket chain 11 and a air ofgear wheels 12 and 13 inter-connect the upper and lower units so that by drivin one of the gear I wheels or one of the sha ts 2 or 7, from any suitable source of power, the two airs of chains will co-act with each other in timed relation.
The upper sprocket chain carries a series of cleats 14, preferably of dove-tailed shape,
and likewise the lower chain carries a serles of cleats 15 of similar shape.
In carryin out my improved method I preferably ta e a sheet of water-proof paper, the water-proofing preferably being of an asphalt nature, support the roll at 16 and lead the paper sheet 17 between a pair of rolls 18 to the machine proper.
A pair of blowers 19, adapted to blow hot Specification of Letters Patent.

air on the rolls and the paper, may be utilized to warm the paper, or any other suit able method may be employed.
, The paper reaches the machine at the point 20 in a warm and more or less plastic condition and is there received between the series of' cleats l4 and 15 and formed into a series of dove-tailed corrugations, as shown in the drawing.
Blowers 21 direct streams of cold air onto the formin cleats and the paper they carry, thereby chilling the paper, and blowers 22 further serve to cool the cleats after the paper has left the machine at 23.
I have found that in forming roofingpaper made of felt or paper base impregnated with asphalt into a corrugated or dove-tailed shape, a considerable amount of.
pressure is required to make the sharp bends, and this necessarily increases the cost 'of manufacture.
By warming the paper before it reaches the machine I am able to form the corrugations with a minimum amount of power, and
by coolin the paper while it is still held between t e cleats and while it is traveling on the horizontal portion of the chains, I set the corrugations into a substantially permanent'shape'so that when they leave the machine at the points 23 the paper is cooled, properly shaped, and from that point on may be worked as desired, as the corrugations will hold their relative position much better than had they been formed cold.-
I find it of considerable importance to have the dove-tailed shaped cleats 14 and 15 so positioned in regard to each other that the paper is held tightly against the cleats,
so that it is chilled by the cleats as it is thus held in intimate contact with them, and the setting of the dove-tailed corrugations is thus expedited.
Instead of warming the paper by blowers 19, or some such means, it may be run directly from the water-proofing bath to the .machine and will, in that event, bewarmed faces of the corrugations, although the paper itself could not readily be formed into a sharp corner at that point.
The paper is formed into a dove tailed corrugation, but the asphalt flows under pressure in the paper and assumes a new relation with the paper, and when it is chilled by the forming means it takes a stiffened form with the corrugations set, so that the tendency is for it to return to the form which it had while in the forming means, should it be sprung out of its shape.
This, of course, is mainly on account of the setting of the asphalt and not on account of the forming of the paper. Were the idea merely to form paper into corrugations, a series of hot forming means might be better than the method disclosed herein, but where the asphalt, or other water-proofing compound, is being actually molded into shape and then set, the method of running the paper into the forming means While warm and chilling it after it is molded, produces a result that is, so far as I am aware, impossible to achieve by other means.
While in describing my method I have set up a certain series of operations and shown a specific type of machine, I do not wish it understood that I limit myself in this anner, as it is evident that the inventiori rhay be varied in many ways within the scope of the following claim.
Claim:
The method of forming lath board having dove-tailed shaped corrugations therein, comprising the warming of a sheet of saturated stock, forming a series of dovertailed shaped corrugations in the stock and cooling the stock while maintained in such form whereby the dove-tailed shaped corrugations are set in the cooled stock.
