GRATE.

SPECIFICATION forming part of Letsel-sment No. 698,630, dated April 29," 1902.

Application led March 5, 1901.`

To all whom. t may concern:

Be it known that I, EDWIN R. CAHOONE, a citizen of the United States, residing at Newark, in the county of Essex andtate ofV New Jersey, have invented new and useful Improvements in Grates, of which the following is a specification.

This invention relates to improvements in swinging vertical gratos for stoves.

The object of the invention is to provide a swinging grate of such configuration that the capacity of the fire-pot may be quickly and readily increased or decreased, according to the will of the operator-that is to say, if the grate be locked to position its convexity toward the front a large lire can be made in the iire-pot. On the other hand, if the concave portion of the grate be positioned toward the front then the coal capacity of the fire-pot will be greatly diminished.

A further object of my invention is to provide a reversible vertical grate which will enable the operator to suitably support and house a broiler and drip-pan, thereby securing the benefit of the heat for toasting and broiling purposes, at the same time preserve allthe drips or juicesas they drop.

Many other objects will become apparent in the description to follow, and particularly pointed out in the claims. I

In the drawings forming a part of this speciiication, Figurel is a vertical section of a portion of a stove, showing the application of my invention, the grate being positioned to enlarge the fire-pot. Fig. 2 is a similar view showing the grate turned to diminish the size of the re-pot. Fig. 3 is a perspective view of the grate and its supporting-frame. Fig. 4 is a perspective view showing a broiler incased between the frontdoor and the grate, the latter being in the position shown in Fig. 2. Fig. 5 is a detail view of the door-hinge. Fig. 6 is a detail View ofa shield used to prevent the smoking of the mica windows in the air trunks or tubes.

The same numerals refer to like parts in al1 the figures. A l

1 indicates a stove having a front opening 2 adjacent the re-pot 3, said opening being covered by a door 4, supported bya suitable frame 5. The door is loosely hinged at its lower corner, as at 6, the hinge connection consisting of serial No. 49,821. or@ man.)

a pivot 7, extending from the rear of the door, anda locking-lug 8, projecting from the pivot. The frame 5 has a perforation 9 and a notch 10, communicating with said perforation, through which the locking-lugS passes when the pivot-pin engages the perforation 9. To fit the door, it is tilted on one end, as indicated by dotted lines in Fig. 4, to permit the locking-lug 8 to pass through the notch 10. Then the door is swung down on its pivot 7, the latter being retained in place by the locking-lug 8 catching against the wall surrounding the perforation 9. This hinge connection is so constructed as to permit of considerable lost motion, the purpose of which will be hereinafter referred to. The door is preferably provided with trunks or tubes 26 to permit a free supply of air topass to the fuel. However, as the details of these devices form no part of my present invention it is not deemed necessary to further describe them.

Secured to or formed with the door-frame 5 lis a grate-supportin g frame 11, composed of end `heads or flanges 13 13 and connectingbars 14 14. The heads 13 have bearings for trunnions 15, which are formed on projec- -tions on the ends of the grate 16, these trun- `nions being locked in position in any Wellknown manner-for instance, that indicated at 17.

. The grate 16 is composed of a series of parallel hooked shape bars 18, spaced apart and connected at their ends, as indicated at 19. In cross-section each `bar is somewhat beveled on both sides to offer as little resistance as possible to the air as it passes to the fuel.

` On the upper and lower edges of the grate is a perforation 20, with one of which a lockingpin 21, preferably in the top of the frame 5, engages when it is desired to hold the grate in a given position.

Betweenthe frame 5 and the top of the grate is a suitable space forminga free passage between 4the space behind the door and the re-pot, the purpose of which is to permit the gases behind the door. to be drawn into the fire-pot when the door is opened.

When the convex side of the grate is turned toward the front, it brings the parallel bars in close proximity with the mica windows 25 in the trunks 26, and not infrequently this relationship causes the accumulation of soot IOO ` shield is used are almost closed, permitting re of medium size to be made.

ot' a sufficient current of air, but not open enough to cause the smoke and soot to collect on the windows. Y

The lower portion of the frame 5 and the bottom grate 31 are so constructed and arranged as to form a pocket 32 to accommodate a drip-pan`33, which is approximately of V shape in cross-section and is composed of the inclined sides 34, ends 35, and handle 36. As disclosed in Fig.`2, the pan may be supported by lugs 37, resting on the front grate, and the handle, resting on the frame 5. A In conjunction with the front grate and the drip-pan I use a broiler 38 of any wellknown type. The broiler is supported by rests 39 on the lower part of the frame 5 and a hook40, seated in a slot 41, formed in a lug 42 in the frame 5. The handle of the broiler projects up through a notch in the door and is always in convenient reach of the operator.

The operation of my invention is substantially as follows: In extremely cold climates, where a large fire-pot is a thing of necessity, the frontgrate 16 is swung on its trunnions to the position shown in Fig. 1, when the lockpin engages the perforations 2O and the grate is fixed. By reason of the `position of the trunnions and the curved hooked end of the grate the vertical portions of the bars are some distance from the front extremities of the bottom grate. However, the latter are in line with and practically touch the extreme end of the hooked portion of said bars. The two grates form an unbroken front and bottom grate-section. As before stated, when the front grate is turned in this position the shield is employed, this by reason of the close proximity of the grate-bars to the mica windows. Should, however, it be desired to diminish the size of the fire-pot, the pin 21 is removed, the grate turned as shown in Fig. 2,- and the pin 21 inserted in theopposite perforation in the grate. With the parts in this position the shield 27 is removed and the grate-bars are nearer the center of the iire-pot, the straight portion of said bars being now at the bottom and the lower ends abutting against the front of .the lower grate, while the hooked ends of said grate are at the top. This position, like the one previously described, presents practically an unbroken front and bottom gratesection, and yet the width of the tire-pot has been materially decreased, which enables a With the grate-bars turned inwardly quite a considerable space is formed between the door 41 and the grate, in which space the broiler is supported. To apply the broiler, the door is thrown up and around on its pivot, the drippan is dropped in its seat, the hook on the broiler is slipped in its seat, and the lower end caught by the rests. With the parts in this position it stands to reason that the meat being broiled receives every advantage from the surrounding temperature. Not only is the broiling action going on, but the juice incident to such action is caught and readily preserved, the drip-pan being so located as to be almost out ot' reach of the excessive heat,cooling somewhat the temperature of the juice. Should it be preferred to incase the broiler, the door 4 can be almost closed, so much so that to all intent and purposes the broiler will be out of sight. The door does not cover the entire opening when Yso used and is made to adapt itself to this position by reason of the lost motion between the hingejoint. This allows a sufficient quantity of air to pass in around the door to the broiler,which adds considerably to the broiling action.

I-Iaving thus described myinvention, what I claim is-'- 1. A stove comprising a casing having an opening in one of its walls, a tire-pot adjacent said opening, and a grate extending from the top to the bottom of and pivotally supported horizontally in said opening in the casing,- adapted to be reversed to increase the size of the tire-pot in one position and decrease said tire-pot when turned over in the opposite position, substantially as described.

2.
