RANGE.

Application iiled February 12, 1927. Serial llo. 167,735.

This invention relates to improvements `in ranges and is constructed from sheet steel or iron and is more particularly 1ntcnded for use in a gas range.

One feature of the resent improvement 1s the construction of t e frame that encloses the. oven and broiler doors and the door itself for the purpose of making an eiicient smooth and sanitary construction.

Another feature of the invention is combining with the frame a journal block and with the door a hinge block cooperating with the journal block, both the said members being enclosed within the frame and the door.

A further feature of the present invention is to so construct the journal block that it is adapted to receive and support across shield for the purpose of protecting the 2o. adjacent parts from the excessive heat of the oven or the broiler.

Another feature of the present im rovement it to so construct the journal locks that the cross shield is supported by the journal blocks and held against endwise movement without the use of any bolts or screws.

The said improvement also relates to the form of the shield whereby the outer member of the shield is supported by the journal blocks and the inner member is supported by .the outer member, the two members adapted to receive an asbestos or other noninflammable packing, whereby the said device efficiently acts as a means of protection to itself and to the adjacent parts from the heat of the burners.

Another feature of the present improvement is combining with the journal blocks an inner and outer part shield, the outer part shield having its upper and lower edges turned inwardly, downwardly and upwardly respectively, andthe inner part having its edges shaped to interlock with the said edges of the outer. part, the whole device construced to cooperate with and be permanently supported by the said journal blocks.

A further feature of the present invention pertains to the construction and coop- 5@ eration of the journal blocks, the hinge blocks and a two-part rod, the outer end of the two parts passing through the hinge blocks and into the journal blocks, and a coil spring surrounding the said two parts of the rod, the two parts of the rod being supported ina manner whereby the spring acts as a means of holding the said doors closed.

Another improvement of the present invention pertains to the construction of the hinge blocks whereby they are adapted to receive the ends -of the supports or catches for limiting the movement of the doors to horizontal positions, the holders or catches having their inner ends constructed to cooperate with the frame or the journal blocks to support the doors in their horizontal positlons. l

Other features of the invention will appear from the following description.

Figure 17 is a perspective view of the hinge rod, the same being partly shown for the purpose of illustrating the reduced end of onevpart of the rod and the otherl end adapted to receive the reduced end.

In Figure 1 I have shown a front view of the complete range, the left hand side 1 being the open burner part of the range, while the other side 2 is the oven and broiler part of the range. In this figure, 3 1s the oven door and et the broiler door. In the form of the invention here illustrated, the frame 5 is composed of a single piece. By this it is meant that its upper end 6, its lower end 7 and its cross member 8 are of one piece stamped from a single sheet of metal. This frame is made of an improved cross sectional shape, and it is made of such form that it is very efficient, smooth and sanitary in its formation.

It is Well known that ranges are great collectors of dust and dirt, and one feature of this present invention is to so form this frame in cross section'combined with the cross section of the said doors whereby the same can be readily kept free from the accumulation of dirt, germs, and the like.

By reference to Figure 8 the contour of the frame is shown, and Figure7 shows the same from the front. From Figure 8 itl will be observed that in general form the frame 8 is U-shaped, it having outwardly bulged portions 9 located just above the cross meinber 8, and the outline of this bulged portion is such as to make it so that it can 'be readily cleaned. By reference to the same figure, it will be observed that the upper end of the frame is bent inward insymmetrical form at 10, then downward as at 11 and then a short inward bend 12. These bends are all made so that it can be readily cleaned. This construction further produces an outward bent portion 13. At' its lower end this portion is not so decided since it extends downward as shown at 14 and is provided with suitable hole or holes 15 vfor connecting the' said frame to the range structure 17.

The frame 5 is also provided with an outward bulge 18 located at its outer side just above its portion 13. The outwardly bulged portion 18 agrees with the outwardly --bulged part 9. Attention is directed tothe fact that the cross member 8 has its -upper edge 19 turned inward and its lower portion turned inward corresponding. to that described at the upper part of Figure 8. Therefore reference letters and other description of this part of the structure is wholly unnecessary.

By reference to Figure 6, the cross sectional structure of the door 3 is clearly shown. It will 4be observed thatits free edge 20 is bent inward, thus making a deep structure, the said inner end at its lower corners 21 being bulged outward to its edge, as shown at 21, Figure 1, for the purpose of receiving the hinge block to be described presently. f

Referring particularly to Figure 5, the construction and operation of the journal blocks will be described. These blocks in general outline are substantially L-shaped, the lower leg 22 being substantially short, while the upper leg 23 is elongated upwardly. By reference to Figure 4 it will be observed that this journal block in cross section is substantially the same as the crossI section of the frame and that it is embraced by the cross sectionv of the frame whereby it serves among other things, as a brace for the frame. Its outer edge.2t is provided with a bolt opening through which a bolt 25 passes for the purpose of holding the upper end thereof in position, the lower end being held by a suitable bolt 26 that passes through .it to the frame. These two bolts 25 and 26 serve to permanently hold the journal block to the frame. The lower end 22 of the journal block is provided with an outwardly bulged portion 27, its inner end having lips 28 and 29, located ont of lineand between these lips the end of theinner shield member 30 is passed. The above described construction applies to both of the journal blocks, which makes it unnecessary to refer to the other journal blocks. It will be observed, therefore, that the inner member 30 of the shield is held between the ends of the bulged portions 27 and the said lips, therefore serving to hold it permanently in position. In assembling these members, one

of the journal blocks would be placed in po-` sition and then the inner shield member and the other journal blocks made to engage the other' end of the inner shield member 30, thus locking it in its-position.

From Figure 9it will be observedv that the louter shield member has its portion 31 bulged whereby it fits the bulged portion 27 and fits between the lugs 28 and 29. This llo shield member also is bent downward at 32 downwardly. The ends 36 of this shield member are extended foi the urpose of littin on the inwardly extendingy bulge 27 an for the pur ose of making a closed structure with t e door lining 37, which fits against the inner edge of the shield member throughout its length. This lining 37 has its edge bent inward as shown at 38 and it fits within the edge 20 of the door 3.

The inner shield member 39 has the peculiar form clearly shown in Figures 6 and 11. It will be observed that its inner edge has a double upward bend as illustrated at 40, and its lower edge a similar bend 41, and that the upper bend is of larger dimensions than the lower bend. The upper edge 40 of the member 39 fits within the U- shaped bend 35 of the up er ed e of the outer shield and its lower e ge 41 ts within the lower U-shaped bend 34 of the said outer shield member. Consequently this member 39 is likewise held in position by having the ends of the upper edge 40 strike the end of the bulged portion 27 of the hinge block, the said member 39 being placed in position on the outer member before placing on the last journal block. From the foregoing description it will be seen that there is a space between the inner and outer shield members, and a part of this space is'filled in with asbestos 42 or any like material. It will be observed that this asbestos stands in a vertical line and it serves tov protect the hinge members from the heat and flame of the burner in the broiler part of the range, as well as to protect the outer shield member from said heat.

Attention is directed to the construction of the upper end ot the inner shield member 39 by having its horizontal portion 43extending beyond the lip of the U-shaped bend 35 of the inner shield member 31. This shoulder 43 forms a support for the floor 44 of the oven. ln .the construction here shown, the ovenfloor 44 has its edge 45 turned downward and resting on the shoulder 43. Therefore this shield member is so constructed that in addition to acting as a shield, it also acts as a support for the front end of the floor of the oven.

By reference to s'ame figure of the drawing (Figure 6), the said construction ol the lining 37 and the means by which the lining is supported, are shown. This consists essentially in a member 46 that has its upper end 47 bent laterally and attached to the lining 37 by suitable bolts 48. The lower end of this member 46 is bent inwardly as shown at 49 and engages the inner side of the door 3. This door is provided with suitable outwardly bent portions 50 on which the stems 51 of a handle 52 engage, and the end 49 is also bent to fit Within this bend 50 and screws 53 pass through the bent portion 49 and the wall of the door and into the stem 51. In this manner the upper end of the lining and the handle are attached to the door 3. The inner or lowerv end of the lining, 37 rests upon the hinge block 54 and is attached to the hinge block by suitable screws 55. It will be understood, of course, that there are two bearing blocks 23 for each door, same being the upward extensions of the journal b ocks, one located to cooperate with the hin e'block attached to the lower portion `of t e doors in a manner to be presently explained. -Therefore .it is unnecessary to describe the other block as it is constructed exactly like the one already described. f

In Figures 2, 4 and 6 the hinge blocks are particularly shown. These hinge blocks 54 consist essentially of L-shaped members which comprise vertical leg ortions 56 and horizontal leg portions 57. uitable attaching bolts 58 pass through the upper ends of the leg portions 56 and the door and the lower portion of these hinge blocks is attached to the door by suitable connecting bolts 59. In this manner the hinge blocks are secured to the door. It will be noted that the hinge blocks are attached to they lower outer corners of the door.

For the urpose of forming a bearing on which the door turns, a two-part rod is provided. One part 60 passes through the lower leg^57 and has its end fastened to the journal block 23 by a screw 61 passing through the journal block and engaging the extremity of the part 60. The other part 62 of the bearing rod passes through the leg 57 and is fastened thereto by a screw 63 which passes through the said leg portion and engages the part 62. Therefore the parts 60 and 62 are relatively movable when the door is moved on its hinge. This is accomplishedby providing the part 60 with 'a reduced projecting end 64 that loosely enters a longitudinal opening 65 formed in the inner end. of the part 62 o fthe hinge rod. Surrounding the inner adjoining ends of the two parts 60 and 6 2 is a suitable spiral spring 66, the respective ends 67 and 68 of the spring being attached to the respective ends of the parts 60 and 62 of the rod by suitable screws 69.

It will be understood from the foregoing explanation that the outer end of the npart 60 of the hinge rod is made fastto the journal block 23 or may be attached in any manner to the frame ot the door, the lower leg tension can be readily placed on the spring while the rod 62 is made fast to its its lowermost position.

by inserting a suitable tool or wire in one of the openings 71 and turning the part 62 until the proper tension is obtained, when the screw63 is turned in, and the parts are ready to operate. ln this manner the coil spring is made to act as means for closing and holding closed the doors as will be readily understood.

lt is essential that some means hotprovided Vfor limiting the downward movement ot' the door and holding Iit in a horizontal position. The means are shown consisting preferably of atlat metallic member 72, the end 73 thereof being pivoted near the cxtremity of the vertical leg 56 of the hinge blocks. 'lhis is accomplished by passing a suitable screw or other bearing 74 through the leg portion 56 and having its end extended and passing through the extremity of the said member 72. For the purpose of ac onnnodating the member 72, the hinge block has its edge cut out as shown :1t-75 to accommodate the end of the member 727 thereby the end 72 is held between the hinge block and the inner side of the bend 20 of the said door. By turning the member 74 and taking it out of position, the lower extremity of the member 73 will be released. Suitable openings 76 are formed in the side fianges of the frame 5, and through these openings the upper ends of the member 72 loosely pass. Attached to the upper end of the member 72 is a suitable block 77 by means of a screw 78. The inner end of this block or stop member 77 is formed at an incline as shown at 79. This incline strikes the journal block 23 at substantially the point 80. Of course it will be understood that the walls of the openings 76 serve to hold the member 72 against upward movement and therefore lock or hold the door in The block 77 in addition, servesfas a Weight to hold the inner end o f the members 72 to their proper positions and is in a sense a balance weight for the free end ofrhthe member 72. For the purpose of,holding the doors in a closed position, the members 72 are provided with notches 81 which form shoulders 82 that engage the journal blocks substantially at the point 80. When the door is closed, this shoulder 82 drops behind the part 80 of the journal blocks so that a sudden pull is necessary to cause the members 72 to be free of said engagement, and after this free movement is accomplished, vthen the door will readily open. In this manner locks or catches for holding the doors closed is provided and the other ends of the same members serve as means to limit the distance the doors will open. The spring of course, will be adjusted to a point that when the door has reached a horizontal position, the weight will be sufficient to hold them in that position. Since they are to be closed, a slight upward pull will carry the door past a point when the springs will close the doors if they should be released.

At this point attention is called to the fact that the lining 87 of the door and the floor 44 of the oven are exactly in a horizontal line, and that this enables the pans and other things to be moved back and forth over the. floor to the door and from the door to the floor of the oven without lifting them. This will be found by users to be extremely convcnient.

For the purpose of enabling the oven or the broiler doors to be removed from the vfront without the necessity of first removing the lining of the oven or the broiler or disturbing any bolts of the range proper, the two-part hinge rod may be moved inward or collapsed until the. extremities of the said two-part rod are released from the journal blocks, when the door can be readily removed. ln order to accomplish this it is only necessary to remove the lining of the door. After this the screws 61 and 63 are loosened and one end of the spring 66 removed to release one end of the spring. This having been done by moving the inner ends of the two rods together, their extremities are released from the journal blocks as will be readily understood. y
