Y SPECIFICATION forming part of Letters Patent N0- 771,8'7'7, dated October 11, 1904.
Appncason med Apriizg, 1904. sesamo. 205,592. (Nomad.)
To a/ZZ whom it may con/cern.-
Be it known that I, GUs'rAv KUEBLER, a subject of the Emperor of Germany, residing at Saginaw, county of Saginaw, and State of Michigan, have invented certain newand useful Improvements in Ovens, of which the following is a specification.
My invention relates particularly to baking-ovens of the class in which draw-plates are employed which are mounted to slide horizontally into and out of the oven. These plates When drawn out for setting or drawing a batch have heretofore been supported outside the oven by stationary frames or by supports carried by the plates and resting on the ground or on rails outside the oven.
The object of my invention is to provide means wholly within the oven for supporting the draw-plates in any position to which they may be moved.A Y
In carrying out my invention I provide each oven with fixed longitudinal rails which serve as guides for horizontally-sliding rails and which securely and rmly hold said sliding rails in a horizontal position both when they are inclosed in the oven and when they are withdrawn therefrom to the desired eX- tent for setting or drawing a batch. Antifriction devices, such as balls, are interposed between the sliding rails and the xed rails, and suitable stops are employed to limit the movements ofthe balls and the rails relatively to each other. Each set of sliding rails supports a draw-plate or tray which is mounted to lide longitudinally or horizontally on the rai s.
My improvements are especially designed for use in what are known as draw-plate baking-ovens; but they may be used in bakingovens and drying-ovens of various types.
In the drawings, Figure l shows a longitudinal section of a draw-plate oven embodying my improvements on the line 1 l of Fig. 2. Fig. 2 shows a transverse section'thereof on the line 2 2 of Fig. l. Figs. 3 and 4c are detail views,- on an enlarged scale, showing particularly'the manner in which the drawplate is carried and the sliding rails are supported and guided. Fig. 5 is a plan view of the sliding rails connected by cross-pieces and which support the draw-plate. Figs. 6 to l0,
inclusive, show a modified form of an oven' constructed in accordance with my invention. Fig. 6 shows a longitudinal section on the line 6 6 of Fig. 7. Fig. 7 shows a transverse section on the line 7 7 of Fig. 6. Fig. 8 is a detail View, on an enlarged scale and in section, showing the manner of supportingand guiding the draw-plate and sliding rails. Fig. 9 shows a vertical section on the line 9 9 of Fig. 8. Fig. 10 is a plan view of the sliding rails connected by cross-pieces. Fig. l1 is a detail view in cross-section, showing a further modication.
The walls A of the oven and the chambers and liues therein may be constructed in any suitable way. They form no part of my present invention. I have shown a double-deck oven, the baking-chambers B being shown one over the other; -but any suitable number of baking-chambers may be employed, and they may be arranged in various ways.` In Figs. l and 2 I have shown each baking-chamber as being provided with two longitudinal guide-rails C, preferably made of channelbeams arranged longitudinally in recesses in the two opposite side walls of the oven with their parallel upper and lower ianges c projecting toward the interior of the oven. These beams constitute guides for a frame D, consisting of two parallel rails d, connected by cross-pieces d and held thereby such a distance apart that the rails d are held within the channel-beams, as clearly shown in Figs. 2 and 3. Preferably the anges c of the beams are provided with strips E, grooved to receive antifriction devices, such as balls F, and provided with stops e to limit the movement of the balls. The rails d are provided with similar grooved strips d2, and they are provided with stops Z3 to limit the movement of the balls and to at times engage the balls and carry them against the stops e in the manner hereinafter explain ed. Each trame Boarries adraw-plate or tray G, of ordinary form, but which, as shown, is provided on its under side with strips g, formed with stops g. Each tray rests on two axles H, carrying wheels la,
that enter the rails Z and are free to move longitudinally therein to an extent limited by stops on the inside of their lower flanges. The channel-beams C are located, preferably, about midway between the top and bottom of the baking-chamber, leaving ample space around the trays 'for the free circulation of hot air. rIhe trays move freely on the rails and are out of contact with the walls of the chambers at all times.
It will be observed by reference to Fig. l that when the sliding rails are drawn out they are firmly and securely held in a horizontal position solely by the fixed guide-rails C. There are no outside supports, and the rails do not come in contact with other parts of the oven. It will also be observed in Fig. 1 that the upper tray G is entirely outside the oven and is supported solely by the rails. Fig. l also shows the'position of the several parts when the rails and draw-plate or tray have been moved bach into the baking-chamber. It will be observed that none of thc part-s project beyond the oven-door, and there are no supports, rails, or other fixtures outside the oven.
In order that the trays may be supported when drawn, it is necessary that the sliding rails should fit closely the fixed guide-rails and that stops should be provided to limit their outward movement, so that a sufficient portion of each rail shall remain within the oven to prevent the front ends thereof from dropping or moving out of a horizontal position. It will be observed also that the stops which limit the movement of the tray on the rails are so located as to prevent the tray from moving forward to such an extent that there will be any possibility of its being tilted forward by shifting weights, and the stops are also so located as to cause the plates to come to rest when they have been moved rearward to a suicient extent on the rails. The plates can be very quickly withdrawn or inserted and the antifriction devices permit great freedom of movement. rIhe plates merely rest on the axles H, and therefore are free to move across these axles, while the axles, with their wheels it, are free to move in the sliding rails, and the sliding rails have freedom of movement in the fixed guide-rails. While there is the great freedom of movement above referred to, the stops and balls are so arranged as to prevent undue movement at any time.
While it is preferable to use separate strips E and d2 to carry the stops, as shown in Figs. 3 and 4, the stops may be formed on or secured to the rails.
In Figs. 6 to lO, inclusive, I have shown a modification. Channel-beams C are employed; but the flanges c are embedded in the walls of the oven, and to the outer faces of the channel-beams are secured angle-bea`ms C2, having flanges c3, arranged one above the other to form guide-rails for the sliding rails D. These rails D are connected by crossbars D2, as indicated in Fig. 10. The rails D' are preferably formed of channel-beams and overlap the flanges 03. Antifriction devices, such as balls F, are interposed between the flanges of the rails D and the fianges o3, and stops e' are provided to limit the movement of the balls. Preferably the stops are formed on separate strips E and (3*, attached to the rails D and the flanges c3 in the manner indicated in Figs. 8 and 9. By this arrangement the rails D' may be moved back and forth on the fixed rails as guides, their upward movement is limited, and they are held securely and firmly in a horizontal position, as shown in Fig. 6, solely by the fixed guide-rails and without the user of external supports. The trays G instead of resting on axles H in the manner shown in Figs. 1 and 2 rest on antifriction devices, such as balls F, as shown in Figs. 8 and 9. Preferably strips J are attached to the under side of the trays, and they are provided with stops j, which vlimit the movement of the trays on the balls. The rails D are also provided with stops K, which limit the movement of the balls F'. The operation is similarto that before described in connection with Fig. l.
-In Fig. 6 the upper draw-plate is shown outside the oven, while the lower draw-plate is within the oven. When the upper drawplate is moved back, the front balls F will be moved against the stops K in rear of them and the further inward movement of the drawplate on the rails D is prevented. In like manner when the rails D are moved inward the front stops at :v come in contact with the balls at w and move these balls rearward to the position shown at m2 in Fig. 6. \I` he balls at m3 are moved rearward in a similar way to the position shown at wf. In this way freedom of movement is afforded and yet the parts are all properly supported at all times.
Instead of securing the fixedrails to the side walls of the oven they may be removed from the sides and supported at their ends or in any suitable way some distance from the side walls, as indicated in Fig. 11. This is a good arrangement when the draw-plate is very wide, as it prevents sagging of the plate in its central portion.
I am enabled by my improvements to move each draw-plate to a position entirely outside the oven, and the draw-plates may be lifted from the rails and taken away without disturbing the rails, which are supported solely by the fixed guide-rails. When the parts are in the oven, the space at the front of the oven is entirely clear. The parts are so assembled that the draw-plates are held far above the bottom of the oven, so that there may be a free circulation of air around them.
I claim as my inventionl. An oven provided with fixed longitudi- IOO IIO

3. An oven having within it ixed longitudinal rails provided with upper and lower iianges, sliding rails supported solely by said longitudinal rails and guided by said anges, and antifriction devices interposed directly between the sliding rails and the upper and lower flanges of the xed rails, and a drawplate arranged wholly above the tixed rails and sliding rails and supported by said sliding rails.
