Heating Drum.

No 86,270. Patented Jan. 26, 1869.

Letters Patent No. 86,270, dated Janua/ry 26, 1869.

FRICTION-HEATER FOR MILLS, 8L0.

The Schedule referred to in these Letters Patent and making part' of the same.

To all whom it may concern.-

Be it known that I, D. H. BALL, of Enterprise, Gaineron county, and State ofPennsylvania, have invented a, new and useful Heater for Heating Mills, 85c, and I hereby declare the following to be an exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, in which- Figure 1 represents a top View of the heater.

Figure 2, a cross-section.

Figures 3 and 4; are sectional views of the interior of the cylinder.

The nature of my invention consists in the construction of acast-irou drum, in two halves, having a fanwheel inthe centre, one half stationary, and the other half revolving with the axle, the friction of the two halves creating heat, and the heat regulated by a lever that adjusts the two halves closer or wider apart, so as to increase or lessen the fiietion, the drum being attached to the shafting of any machinery, for the purpose of heating mills or machine-shops, or can be attached to the axles of cars, for the purpose of heating railway-cars.

A represents a frame that supports the devices.

B, the shaft upon which the revolving drum 0 opcrates.

D is the adjustable and stationary drum, is adjusted by the pivoted lever E, and held stationary by the lever being fastened to its hub G.

The centre of the two drums is hollow, and in this chamber, H, a fan-wheel, J, (that is attached to the shaft 13,) operates, air passing in at side apertures, K K, of both drums, and passing out through apertures in a groove, L, the heated air discharged through a pipe, M.

When the drums O and D become red hot by friction, by the lever E the drum D is adjusted, and the friction lessened, and the heat regulated by thus'separatiug the drums.

The upright lever N is adjusted againstthe leverE at any time, to increase the pressure of the drum D against the opposite drum, G.

The fan J drives out the heated air, into a room of a mill, for heating-purposes, or for drying grain, and also for Warming railway-cars.

- The casing P, that surrounds the drum, is stationary, and a su fiicient distance from the drum to prevent the heat that may be generated from doing any damage to the building or car to which itmay be attached.

The wearing away of the drums, from friction, might be supposed to be great and rapid, but such is not the case, as, after running but a short time, their faces become glazed over, as it were, which very effectually prevents their wearing away, and being adjusted 'by separation, wear very little.

I do not claim friction-drums, or heaters, as they have been used before; but

What I claim as my invention, and desire to secure by Letters Patent, is

The construction of the drums O and D, with their apertures K, groove L, and outside case P, when arranged and combined with a fan-wheel, J, in the centre, as herein described, and for the purposes set forth. Witnesses: D. H. BALL.
