IMPROVED APPARATUS FOR' APPLYING ROOFING-COMPOSITION T0 FELT.

. it is termed, which forms the body ofthe roofing, a coating of sand being generally applied to the surface after the composition has partially cooled. This compound is prepared in a hot, melted state, and, as it hardens so rapidly in cooling, it is essential that. the coating be quickly applied. It should be not only quickly,y

but uniformly distributed, and convenient means for removing and handling the rooin g, for cooling and applying the sand-coating at the proper time, becomes a matter of importance.

The object of my improvements is to provide a simple and cheap apparatus for accomplishing these results.

The apparatus consists of a removable bed or table, upon which a strip of the felt tobe treated is secured, which bed is supported in a frame or way, on which rests or slides the hoppers for distributing the roofing-composition and the sand that is applied, either by sliding the bed under the hoppers or by sliding the hoppers over the bed, the same hoppers and frame-way being used with any number of beds, each of which, with the roofing thereon, being removed from the frame as fast as coated, and left to cool while another is substituted.

In the accompanying drawings, Figure I is a longitudinal vertical section of my apparatus. Fig. ll is a plan, and Fig. III is a cross-section, of the frame, showing the sand hopper in elevation.

Like letters of reference refer to like parts p in each of the figures.

A A are the two longitudinal pieces, secured in place in any-suitable way and forming the rails or way on or between which the hoppers or bed slide.

B is the bed, of the width of a strip of felt, and of any convenient length, say from twelve to twenty-five' feet. It is shown constructed with side pieces, b, which project a little above the main bed, for a purpose presently to be explained, and which terminate in handles b', by which the bed is handled. c are wedgeshaped cross-bars, connecting the side pieces, b, at the ends of the bed. These bars are for securing the felt d to the bed. The ends of the felt are turned down at the ends of the bed, and the wedges c inserted, which clamp them to the former, as shown. Any other suitable means for fastening the felt maybe substituted.

F is the sand-hopper, and E is the loppcr for the roofing-composition.

The frame-way 'A is shown constructed so as to permit the sliding of either the bed or the hoppers. on a rabbet, a, between the ways A A, so as to slide thereon. The hoppers are shown as resting on these ways, being retained thereon by means of a groove in the under edge of the end pieces thereof, to which the upper edges of the ways conform. 'The hopper E, for the composition, is made with a discharge, e', eX- tending across the bed the width ofthe plane portion, and with a scraper or plate, e, by which the thickness of the coating is regulated. The edges of the felt resting on the raised side pieces, b, of the bed will not receive a coating, as the ends of the hopper are purposely designed to run in contact therewith, so as to prevent the composition working out at the edges against the ways, which would obstruct the sliding of the bed or hopper, as the case may be.

The sand-hopper may be constructed, as shown, with the discharge at'its rear edge controlled by a slide, f, actuated by a lever, f, by which the aperture may be opened or closed, as required.

From the foregoing description, the operation of my apparatus is obvious. The strips of felt being attached to the different beds, one of them is placed in the frame-way, and the hot, prepared composition, in the required quantity, let into the hopper E, by means of a spout or otherwise, and the bed or hopper moved quickly in the direction indicated by the arrow, the composition being equally distributed over the surface of the'felt. It the yhopper contains more than the quantity of the compound required for coating a strip, it

is run onto the sand at the cnd of the bed,

The bed is represented rest-ing when, after it cools, it can be collected without Waste. rlhis bed is now removed froln the Vhat I claim as my invention is- The combination ot' the, removable bed B frame, and another arranged in its place, while with the Ways A A and hoppers E F, either the former is left for a few minutes to partially cool, preparatory to sanding. It is then replaced in the frame, or in another similar one, md the sand applied by using the hopper F, vhieh distributes it in the same manner in vhch the composition was applied.

or both, substantially as and for the purposes hereinbefore set forth.
