JESSE. T. GLYMER,

OF GALION, OHIO.

Letters Patent No. 94,398, dated August 31, 1869; antedated August 25, 1869.

To all whom it may concern Be it known that I, J nssn T. GLYMER, of Galion, in the county of Crawford, and State of Ohio, have invented certain new and useful Improvements in Stove-Pipe Drums; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon, making part of'this specification, in which- Figure l is'an exterior view of the drum.

Figure 2 is a vertical sectional view.

Figure 3 is an outline of the upper cone, showing the arrangement of ventilators therein.

The object of my invention is to construct a neat and ornamental drum, so arranged that the draught can readily be regulated, the degree of heat greatly augmented, the accumulation of soot, ashes, and all other impurities in the pipe or drum, securely guarded against, and all accomplished in asimple, substantial, and practical manner, and with the greatest saving and economizing of fuel.

The great objection to the drums now in use is found in the difficulty experienced in gaining access to the interior of the same, which is often not only desirable, but absolutely necessary, for the purpose of cleaning and repairing.

This ditiiculty arises from the fact that the entire outer casing consists of one close cylinder.

I construct my drum in two sections, each section being conical in form, and united attheir base by means of aflange on the one, which fits closely over the other, forming a perfectly tight joint or connection.

While, by this arrangement, all danger of the escape of smoke, soot, and other impurities, is securely guarded against, it, at the same time, affords the.

greatest facility of access for the purposes of cleaning and repairing.

The form of the drum-the double cone-possesses many advantages over those whose diameter is uniform throughout.

It is also cheaper, more ornamental, occupies less space, and still affords all the surface necessary for the radiation of the heat that is desirable or requisite.

My invention consists in the peculiar arrangement of the interior radiating-cones or funnels, do two being oflikc-dimension.

The diameter of the upperv cone, at its base, is nearly as great as that of the drum at the point at which the sections meet or are united, only a small space being left between theouter line of its circumference and the interior surface of the drum for the passage of smoke, &o., and as the series descends in i the lower cinical section, and toward its apex, itnecessarily diminishes in size in order to conform to its angular slope.

Another great advantage of my invention consists in the arrangement of the cones or funnels on an upright axial rod.

In other drums, where cones or funnels are used for radiating-purposes, they are never sustained by independent or removable bearings, but are invariably supported by means of flanges, metal strips or straps attached to the same, and also to the interior of .the' drum.

A moments reflection will clearly show the disadvantages of such an arrangement, as well as the superiority of mine over the same.

-In the drums alluded to, should you desire, for any purpose, to remove the lower funnel, (and, owingto the greater intensity of heat to which it is subjected, it always burns out before the others,) you cannot gain access toit without removing the entire series; and each being united by three or four metallic strips to the interior of the drum, the .labor and diliiculty of so doing are far. from incousiderable.

By my arrangement, you have only to disconnect the sections of the drum and lift the axial rod out of its hearing or step, and you have the utmost freedom of access to the entire series ,of cones or funnels, or either one of the same desired.

In my arrangement, the upper cone is fastened to the rod by a pin, and the lower one is supported by metallic straps or hands, hanging from the upper cone; those that are intermediate fitting in loops formed in the same.

The axial rod is stepped in a plate arranged at the apex of the lower 'c'one, and is held in position by means of a collar or shoulder arranged or cast on the same.

The upper end of the rod is held securely in a plate or bar arranged in the upper section of the drum.

Another great advantage of my invention consists in the airangement of the damper and valve, and the means of operating the same, whereby the degree of heat is successfully controlled, and the amountof air admitted, readily regulated.

The ordinary plate-damper, secured to a movable or stationary rod, having permanent hearings in the,

pipe or drum, furnishes no feature of my invention.

Many methods have been essayed to render such a damper successful, especially in drums, but with indifferent success; among the most popular of which, theoretically, and, indeed, until their defects were discovered by use' and practical'experience as to their working, were those that operated automatically, commonly known as the thermostal dampers. These are usually operated in the following manner:

To the damper-plate is hinged, or otherwise 'at-. tached, a compound lever. I l

The end of the lever, rests on or is connected with one orimore bars or plates of expansive metal, arranged within the pipe or drum, and running parallel with the sides of the same.

The slightest elongation orcontra'ction of .the metal necessarily moves the damper, and consequently opens or closes the passage for the air.

This method is perfectly arbitrary in operation, leaving you, in reality, no control over the damper.

Should you attempt to retain the damper at any desired point by means of a thumb-screw, or equivalent device, the metal bar cannot be prevented fromexpanding, and consequently will soon become bent; its bow-form so ,weakening it as to render the same entirely worthless.

vMy arrangement is free from all such defects.

In the upper end of the drum, and to' the walls of the same, 1 permanently secure an inverted frnstum of a cone, with an aperture at its apex.

Around this aperture or opening is arranged a valve-seat, in which fits and works a foraminated valve; i

This valve is in no manner connected with the walls or sides of the'drum, but depends for its entire support on a short upright rod, to which it is permanently attached.

This rod is hinged to a bent lever, which projects through an opening in the side of the drum, and sufficiently far beyond the same to furnish'a fulcrum, on which works a short curved lever, which in turn is operated by a rod and thumb-screw, arranged in a suitable casing on the outside of the drum.

By this arrangement of levers and rods the valve is raised and lowered, and consequently the degree of draught regulated-at pleasure.

My invention also consists in arranging in two circular necks, by means of which the drum is attached.

to the stove-pipe, ventilators. 7 These ventilators are for the purpose of admitting cold air to the drum.

The upper one also serves to .remove foul-air from the apartment.

The lower one is also a great aid in regulating the heat in the drum, which may be done by shutting the stove-damper and opening the ventilator..

The whole device is simple and of little cost, and can be attached to and used with any form of cook-- ing or heating-stove, increasing the radiation of heat therefrom and diminishing the consumption of fuel to a very great degree.

To enable othersskilled in-the art to make and use my invention, I will now proceed, to describe its construction and operation.

The drum is composed of two cylinders or sections,

A and A, each conical in form.

The section A is formed .with a flange, a, which fits closely over the base of the-section A, so that when the two are united,.a perfectly tight joint is formed, and the escape of smoke, soot, &c., securely guarded against.

Theedge of the flange a may be serrated or otherwise ornamented, to suit the fancy of the manufacturer or purchaser.

The apex of each of the sections, A and A, is open, and connected with short circular cylinders or necks, B and B, and by means of which the drum is attached to the stove-pipe.

The neck B is provided with a ventilator, N,and the neck B with a ventilator, 0.

-These ventilators, N and 0, are provided with valves a-and o, by means of which they are opened and closed at pleasure, and through their agencycool air is admitted to the drum, the lower ventilator 0 increasing the heat when the damper is closed, and the ventilator N carrying off all the impure air in the apartment.

O is a metallic plate, extending across the lower portion of the section A, and serves as a step or seat by means of .a' collar or shoulder, 'i, as clearly shown in fig. 2.

The upper end of the rod D is retained in position by means of an opening in the plate 0', which is supported by the valve-cone F.

To the axial rod D are attached several inverted cones, E E E These cones are tapering in size, in order to conform to the interior dimensions of the'druln, their diameters being such as to leave a. narrow passage for the air between the same and the drum;

The uppercone E is fastened to the rod by means of a pin or bolt, m.

'To the under surface of the cone E are soldered straps, 'r'r.

These straps are firmly secured to and support the lower cone E, while the cone E enters and is supported by loops, 1" r, arranged midway thestrap or band.

Thus. it will be seen that the entire support of the cones or funnels depends on the axial rod D, they drum.

"The cone E is made of iron or other hard metal, while the others are of tin.

This diifererrce of material is in consequence of the greater intensity of heat to which 'the cone E is subjected.

Near the upper end of the section A, and to the interior walls of the same, is firmly secured an inveited cone, F, whose apex is left open.

Around this opening is a valve-seat, in which rests the valve G.

shown in fig. 2 servesefl'ectually to check the draught upward through the opening in thecone 1*.

rod, H, which is hinged to the bent lever I.

an opening in the section A toafl'ord a fulcrum for the curved cam-lever J to work upon.

This lever J is, connected with a rod, K, which is provided with a thumb-screw, L.

This rod K is arranged and works within a metallic casing, m, secured to the outside of the drum.

By turning the thumb-screw L, the rod K is drawn the bent lever I, elevates the hinged or jointed end quently, the valveG, which enlarges the passage for smoke, 85c. Then, by simply turning the thumbsc'rew L in the opposite direction, you free the bent lever I from the pressure of the lever J, which instantly permits the valve to fall in its. seat and occupy the position clearly shown' in fig. 2 of thedrawing.

I am aware that cones have been used, so arranged that by means of ratchet-bars and pinion-wheels, the same can be moved in a vertical direction, and thus caused to act as dampers.

This arrangement difi'ers entirely, from mine, for my series of cones are firmly connected together and so supported on an axial rod by means of a single pin, that when the drum is in operation, the entire series are heldstationary, the rod resting insuitable bearings. I

thumb-screw L, substantially as desen'bed.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
