DOOR FOR BAKERS OVENS.

SPECIFICATION forming part of Letters Patent No. 635,075, dated October 1'7, 1899. Application filed December 12, 1898. Serial No. 699,091. (No model.)

To ctZZ whom it may concern.-

Be it known that I, WERNER NEUHS, a citi zen of the United States of America, and a resident of Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Doors for Bakers Ovens, of which the following is a specification.

This invention relates to bakers ovens; and it consists of a new construction and adaptation of a door with a counterbalanceweight, whereby a swinging door may be held up when the door is open.

The invention also consists in the combination, with the said door,- of an attachment for operating a gas-light cock in the pipe for illuminating the oven.

These improvements are constructed and combined with the oven substantially as here inafter described, and pointed out in the claim, and illustrated in the accompanying drawings, in which Figure 1 is a front elevation of an oven having my improvements attached. Fig. 2 is a vertical and longitudinal section on line 2 2 on Fig. 1, showing the application and manner of working of the counterbalance"- weight in connection with the door. Fig. 3 is a detached view of the door. Fig. 4 is a view of a portion of the corner of the dooropening, showing the gear as applied and adapted for operating the cock in the adjacent gas-pipe.

A represents the base of the oven, having a fireplace A.

B is the oven or baking-chamber, formed by the two plates 0 D, fixed in the Walls of the masonry.

E is a space over theoven connected by the back space F with the rear end of the the arch A G is a space between the bottom of the oven and the arch and is connected at the front corners by vertical flues at the sides of the oven-doorway. The heat passes to the chimney by the side flues G, leading from said lowerspace G.

This description appertains to the ovens for which patents have already been granted to me. My present improvements are designed as attachments to the said patents.

M is the oven-door, having journals in m at its upper corners, by means of which it is suspended in bearings in the upper corners of the frame of the door-opening. The journal at the left extends through into a chamber N at the side of the door. 11 is a hand-lever ate tached to thesaid journal m.

W is a weight attached to a tilting'lever O, pivoted to the bottom of the chamber N.

P is an arm on the lever H, connected by a link Q to the tilting lever O, byrneans of which the weight is tilted over when the hand-lever is depressed for opening the door. The link Q may be adj ustably attached to both the arm P and the tilting lever 0, so that the counterbalance-weight may be nicely adjusted to operate in conjunction with the door. The journal m at the right-hand corner of the door also extends through the doorframe and is provided with a gear-wheel R.

T is a gas-pipe supported in a lug t on the door-frame and has a burner located in front of a window V in the front wall of the oven.

U is a gear attached to the gas-cock and is in mesh with the gear-wheel R, the purpose of which is to turn on the gas as the door is opened and to turn it ofi when the door is closed.

Having described my invention, what I claim is In a bakers oven, the combination with the swinging door having journals m m supported in the upper corners of the door-frame,- of the lever H attached to the journal m, arm P on said lever H, tilting lever O pivoted in side chamber N, weight W on said lever O, and the link Q connecting the lever O with the arm P, arranged to operate as and for the purpose set forth. I

Signed by me at Cleveland, Ohio, this 5th day of December 1898.
