To all whom it ntf/y concern:

Be it known that i, FRANKDAvrs JACOBS, a

, citizen of the United States of America, re-

siding at Northampton, in the county .of Hampshire and State of Massachusetts, have invented new and useful Improvements in Machines for Making Roofing Material, of which the following is a specification.

This invention relates to improvements in machines for coating a strip of material fed therethrough with strips of another material applied on both sides thereof, and it has special reference to a machine for thus coating a strip of sheet metal in the manufacture of roofing and like material, such as that which forms the subject-matter' of Letters Patent of the United States issued to me on April 25, 1905, and numbered 788,358, the object of the invention being to provide a machine whereby a strip of metal or like ma terial may have applied to both sides thereof, which have previously been treated with a suitable adhesive, another strip of coating material, means being provided to cut this sip into predetermined lengths automatica y.

The invention is fully illustrated in the ac- `companying drawings, in which- Figure l is a plan view of the machine, showing a strip of material therein. Eig. 2 is a side elevation of that side of the machine shown at the top of the sheet in Eig. 1. Eig. 3 is a side elevation of the opposite side of the machine to that shown in Fig. 2. Eig. 4 is an end elevation of the right-hand end of the machine, as shown in Eig. l, and shows particularly the means for shearing oif the lengths of the coating material from the strip. Fig. 5 is a side elevation of the gears whereby the pressing-rolls and feed-rolls are rotated intermittently. Eig. 6 is a sectional elevation on line Fig. l, and shows the gears which operate the shearing devices. Fig. 7 is a side elevation of the gearswhich actuate the shearing devices, showing their inactive position during thetime when the strip to be cutis bein@r coated.

Referring now to the drawings, a indicates the legs or standards on which a trough-like bed b is su ported. Preferably this trough is cast with suitable socketsc on the under side thereof, into which the legs a enter and are secured. The trough-like bed t is closed at both ends, and mounted at each end thereof is a pair of feed-rolls, (indicated byd e at one end and by f g at the other.) Of these two pairs of feed-rolls the lower-rolls e and f rotate in fixed bearings, while the upper rolls d and g are movable relative to the loWerrolls and are held in contact with the latter by means of a weighted arm h, pivoted at near each end of these rolls and bearing a ainst the boxes in which the shafts of these ro ls are seated. In this way a constant pressure may be applied to material passing through these feedrolls, which material is indicated by m.

As shown in the side elevations Fig. 2 and 3, the strip of material m passes under an idler-roll o, located transversely of the bed about midway between its ends. trough-like bed contains the-adhesive solution into which and through which the strip of material is fed by means of the rolls d e and g f, heretofore described, the strip being immersed in the solution during its passage through the trough. The nature of this adhesive when used to manufacture roofingmaterial after the manner described in my said prior United States Letters Patent renders it necessary to apply it to the strip of material in the presence of heat, and therefore'beneath the trough-like bed b a number of burners p are located, preferably for the use of liquid or gaseous fuel, whereby the proper temperature may be maintained in -the adhesive substance in the trough. As

the rollers gandf are located just beyond the end of the bed b, the material m as it passes therethrough lwill carry more or less of the adhesive substance vwith which it is coated, and it is the function of vthese rolls, acting as wiper-rolls, to clear the'surface of said strip of material of all of the latter but the uantity required to effect the adhesion of the coating strip to be ap lied thereto, and there fore beneath these ro ls a drip-pan or receptacle g is provided (see Eig. 3) into which such material as is wiped off the strip by the action of the'rolls may fall, some of it, of course, flowing back on the top of the strip into the trough. To preventy the hardening of this adhesive on the rolls, the latter are made hollow, and through a suitable pipe 1' This' IOO these presser-rolls are constructed in such steam is introduced through the shafts of the rolls to maintain high a temperature in the latter may be necessarylto keep the adhesive substance in a fluid state.

During the passage of the material -m tln'ough the bed and after it emerges from the latter and passes through the various rolls to the point at which it is sheared off into lengths its opposite edges run between guide-strips s, (shown in. dotted lines in the side elevations, Figs. 2 and 3, and in plan in Fig. 1,) these guide-strips extending from the rolls d c to beneath the idler-roll o and from thence to the rolls gf, from which point they extend on to the shearing-point, as shown. A portion of these guide-strips as they approach the shearing-point is shown in Fig.

At the right-hand end of the machine, as shown in the general views, Figs. 1 and 3, two rolls t and i) of coating materia-l are suported one above and the other below the ine of movement of the sheet-metal strip through the machine, a strip of coating mate-- rial from the roll i being carried down around a presser-roll w and another strip from the roll i; being carried around a like roll as, bctween which rolls the material m passes, these serving to press the coating material firmly against the opposite sides of the strip m. Like the feed-rolls heretofore described,

manner that the upper one u' may be moved vertically toward and from the lower, it bcing held in contact with the latter at a predetermined pressure by means of a weight 3 on an arm et, which has the same function the weighted arm z on the feed-rolls (l and g.

At the extreme end of the machine a driving-shaft .5 is located transversely of the end thereof, and on this shaft, side by side, are two broken gears, the inner one, as shown in Figs. i and Ll and indicated by 6, serving to drive the roll :c through the )inion 7, fixed on the end of the shaft of said roll. Referring to Fig. 5, it will be seen that the teeth on this gear extend about three-quarters of the distance around it, and when the teeth on this' gear run off the pinion 7 the edge of a ring 8 will come to a bearing against the flattened surface 9 of a ring 10, secured to the side of the pinion 7, thereby locking the presser-roll :c against rotation until the inactive part of the gear 6 has been rotated past the pinion 7, whereupon the teeth of the gear again mesh with those of the pinion to continue the rotation of the latter. llt is thus clear that by means of the proportion of the toothed part of the gear 6 to the number of teeth in the pinion 7 the presser-rolls may be made to deliver any length of material m and then come to a stop for a predetermined period, which period will be measured by the length of the dead space on the gear 6. vThe presserrolls w and ac at one en( are provided with gears 14 and 15, which intermesh torotate them together, and on the roll a: outside. of the gear 15 is a beveled gear 1.6 (see Figs. 1 and 2) in mesh with the beveled pinion 17 on a short shaft 18,. which in turn, by means of a beveled pinion 1Q, meshing with a similar one 2O on the end of the shaft 21 of the feedrollf, drives this latter roll, and by means of gear connections similar to the presser-rolls the roll f will rotate the roll g above it. The rolls d and e at the opposite end of the machine are similarly equipped with intermeshing gears to rotate together and are positively driven in unison with the rolls f and g bv means of a shaft 22 running alongside of I b O the bed. and having beveled pinions 23 and 24; thereon operatively engaging the beveled pinion 20 and a similar pinion .25 on the end of the roll e. Thus when the teeth on the gear 6 run olf the pinion 7 and the presserroll :1: comes to a rest the two pairs of feedrolls d e and fg are also arrested, and it is at this time that the shearing operation takes place, which will new be described. Outside of the gear 6 and also on the drivingshaft is another broken gear 26, which is illustrated in Figs. o and 7 and which by meshing at the proper time with a pinion 27 on a. shaft 128, supported in suitable standards 29 directly over the drive-shaft, actu.-

ates the blade 30 through the eccentric 'con- 9 nections of the latter with the shaft 28, as shown in Fig. (5, to shear oil' the metal strip 1a, which has been fed thereunder by means of the feeding devices heretofore described, the knife during this shearing movement passing across the edge of the stationary knife 31, all of the above-described parts being clearly shown particularly in Figs. e and G.

it will be seen by referring to Fig. 7 that the part of the circumference of the gear 26 which is provided with teeth is equal to that (',ircun'iferential part of the gear 6 at which there are no teeth, and the two gears 6 and 2G are so located on the driving-shaft that when the gear 6 during its rotation becomes inactive relative to its pinion 7 at the same moment the toothed part of the gear 26 enters in mesh with the pinion 27 to rotate the shaft 2S and actuate the steering devices in the manner described, the pinion. 27 making one revolution, thus carrying the knife down and back. lt is thus seen that the machine is entirely automatic in its operation of coating the-strip of material and cutting off the same in predetermined lengths.

Beyond the shearing devices any kind of a table or chute may be provided to receive the cut lengths of the coated material.

In operation the adhesive substance with which the material is coated is put into the bed I) and by means of the burners therebeneath brought to a proper state of fluidity, the metal strip then being introduced between the rolls d e, carried under the idler- IOO roll .0, thence through the other feed-rolls gv and f. It the machinenow bestarted,'the strip will be fed between the presser-rolls w anda, and the two strips of coating material from the rolls t and o will be carried, respectively,`under the presser-rolls and pressed firmly against each side of the stri of material until a certain predetermined en'gth has passed, whereupon these rolls and the Jfeedrolls become stationary and the shearing device is operated to cut off the length of material thus coated, whereupon the operation is resumed.

Having thus described my invention, what I claim,`and desire to secure by Letterslatent of the United States, is
