SPEGIEIGATIN forming parier Letters Patent No. alegran/dated January 7, 1890. Application filed October 30, 1889. Serial No. 328,729. (No model.)

.To all whom it may concern: Be it known that we, PETER HOOGERZEIL, Jr., and GEORGE F. HINKLEY, citizens of the United States, and residents of Beverly, in the county of Essex and, State of Massachusettshave jointly invented new and useful Improvements in Stove-Ovens, of which the following, taken in connection with the accompanying drawings, is a specification.

This inventionrelates to improvements on that class of stove-ovens in which the ovendoor is connected to a plate or grating, so as A to cause the latter to be automatically and partially drawn out of the oven when the door is swung open and pushed inward during the closing movement of such door; and this our present invention relates particularly to improvements on the United States L'etters Patent granted to us May 28, 1889, No. 403,938, for stove-ovens, and it is carried out as follows, reference being had to the accompanying drawings, where-- i Figure l represents a perspective view of a stove provided with our improvement. Fig. 2 represents a detail perspective view ofthe rear inner corner of the movable grating. Fig. 3 represents a detail vertical sectional i view of the oven-door and its connection to ever they occur on the different parts of the drawings. l

A represents a stove of any well-known l make, and a is the oven therein, as usual.

Bis the oven-door hinged to one side of the oven in the usual manner. I

C is the insand-out movable grating, to which is loosely pivoted at cv the curved link or bar d, the outer end of which is connected to the inside of the doorB as follows: To the inside of said door are secured or cast infone piece with it a pair of slotted ears b b, between which the outer perforated end of the link or bar d is inserted'. `A verticall pin e passes loosely through the slotted ears b b and the perforated outer end of the linkor bar d, and by this arrangement the said -link is free to adjust itself 4relative to the swinging movement of the door, and thereby causing the grating C to move more properly andv easily in theoven as the door is operated.

For the purpose of relieving the friction between the pin e and the slotted ears b b, we provide said pin with an anti-friction roller c', which may be rigidly attached to such pin or j ou rnaled thereon, said roller being adapted to roll against the inside of the doorB during the openingand closing movements of said door, thus allowing the outer end of the link or bar CZ to adjust itself with a minimum of frietional resistance relative to the door during the movements of the latter.

The grating@ is provided at its sides with rollers c c', adapted to roll on the bottom of the oven as the said grating is moved in o1' out. Near the forward end of the oven we locate anti-frictionrollers a a', journaled on stationary pins secured to the oven in any suitable manner, which rollers serve two purposes-namely, to serve as anti-friction bearssl ings for the sides of the movable grating C,

and also as stops to limit the outward motion of said grating, such outward motion being limited by the grating-rollers c c coming in contact with the oven-rollers a a.

To' the rear ends of the grating C are secured the-bearings ff, to the outer ends of which are journaled the anti-friction rollers ff, adapted to roll against'the insides of the oven, and said bearings are preferably made laterally adjustable to compensate for variations in the sizes of the ovens in a manner shown and described in our above-mentioned previous patent, such rollers serving` as antifriction guides for the grating as it is moved in or out of the oven. One of said bearings f, preferably the-right-hand one, as shown in Figs. l, 2, and 3, has journaled to it a hori# zontal anti-frictional roller F, adapted to'roll against the underside of an inclined rib a, attached to or forming a part of the oven a,as show-n in Fig. l. Said rib and roller serve to prevent the grating from being tipped downward in its outer end, particularly if for any reason the link or bar d should be disconnected from the door. The .said rib a Ais made inclined upward from the front of the oven, so as to permit the grating C to be moved freely forward and back Without the IOO roller F coming in contact with said rib a, except when thc grating is drawn nearly out, when the said roller is made to bear against the under side of said rib a, thus serving as a rest or fulcrum to prevent the outer end of the grating from being tipped downward.

Having thus fully described the nature,

construction, and operation of onrinvention, We wish to secure by Letters Patent and claim- Y 1. The oven or box ay and its hinged door B, having the slotted ears b b, combined with the movable grating C, the link or bar d, and the hinge-pin e, having anti-friction roller e', adapted to roll against the inside of the door during the in-and-out movement of the said grating, substantially as described.

2. The oven or box a and its hinged door B, and the movable grating C, connected to said door and grating, as described, combined withthe anti-friction supporting-rollers c c on the grating C and the anti-friction and step rollers a aou the oven, substantially as and for the purpose set forth.

3. The oven or box c and its hinged door B and movable grating C, connected to said door and grating, as described, combined with the laterally-adjustable side rollers c c on the grating, the anti-friction and stop rollers a at on `the oven, the stationary inclined rib a, and anti-friction roller F on the said grating, all arranged and combined substantially as and for the purpose set forth.

In testimony whereof we have signed our names to this specification, in the presence of two subscribing witnesses, on this 18th day of October, A. D. 1889.
