' 8 Claims.

This invention relates to cooking ranges, and has for its principal object to provide a range of this character with a working top .oflset rearwardly and upwardly with respect to a forwardly positioned working top for promoting safety and convenience in use of the range.

Other objects of the invention are to provide a range with an extendable or projectable working top; to provide the working top with a simple latch means for retaining it in projected position; to'provide a roller mounting for the working top for facilitating movement thereof to and from extended position; to provide for insulation of the working top from heat of an oven located therebeneath; to provide a construction wherein the shell of the working top maybe covered with baked enamel; and to provide a metal top that is of substantially rigidconstruction and substantially'free of flexure. I

Further objects of the invention are to provide a range construction that is of pleasing and novel appearance, and which may be kept in sanitary condition. v

In accomplishing these and other objects of the invention, I have provided improved details of structure, the preferred form of which is illustrated in the accompanying drawings, wherein' Fig. 1 is a perspective view of a cooking range constructed in accordance with the present invention and showing the working top in extended position. v a

Referring more in detail to the drawings:

l designates a range constructed in accordance with the present invention, and which includes a base section 2 supporting an oven and cabinet section 3 having a substantially flat top 4.

Spaced from the top I, by a section I, is a cooking top section 6 of substantially the same width as the oven section, but terminating short of the front of the oven section to provide a space for a working top I in the front thereof. The spacing section 5 includes side members 8 terminating short of the front 'of the cooking top 6 so that the front portion 9 of the cooking top overhangs the space for the working top.

The section 6 includes ends to in the plane of the side members 8 and connected atthelr front ends by a panel H. The panel ll carries the various controls l2 for regulating fuel supply to the burners l3 of the cooking top and oven and broiler sections of the range. The burners l3 of the cooking top are arranged in a line series extending across the width of the range and are covered by grids l4. Supported on the rear portion of the cooking top is aback panel section l5 that covers the ovenvent and enhances the appearance of the range.

, The top 4 has the 'end edges thereof spaced inwardly from extended planes of the sides of the cabinet section to form rabbet-like recesses in substantial registry with the end members 8 ofthe spacing section to accommodate substantially channel-shaped tracks l6 and I1. The tracks include web portions l8 arranged vertic'ally and secured tothe vertical portions of the rabbet-like recesses. The tracks extend from front to back of the space supportingthe working top I. Extending" laterally from the webs iii are upper and. lower flanges l9 and20, the lower flanges 20 being provided with upturned lips 2| which cooperate with the webs l8 to provide.

flanges l9 and 20 as clearly shown in Fig. 6. The upper flanges l9 are located slightly below the overhang 9 of the cooking top to provide a space therebetween and terminate short of the front ends of the lower flanges to provide spaces 26 to the rear of'the rollers 23 to permit insertion of the working top roliers'later described. The forward ends of the-guide tracks areconnected by a longitudinal bar 21 also positioned in a rabbet-like recess formed by inwardly spacing the front edge of the top from thefront of the cabinet section. The bar 21 has a forwardly extending flange 28 on the upper edge thereof.

Mounted on the portion of the top 4, directly over the oven space, is ashield'29 having depending sides 30 terminating in footing flanges 3| suitably attached to the top 4'. The'forward edge of the shield 29 projects over the flange 28 and terminates in a downwardly extending flange 32 projecting over the top of the oven so that when the door 33 of the oven is opened, the heat escaping from the oven is deflected from the working top.

.Fixed substantially in the center of the range,

on the top l, is a channel member 34 extending parallel with the tracks ii and i1 and having upwardly directed

flanges

35 and 36 to be engaged by a roller 31 on the working top to'maintain parallel relationship of the working top with respect to the guide tracks and prevent lateral shifting movement thereof relatively to the ends of the range.

The working top 1 includes a carriage 38 on which an outer shell 32 is attached. The carriage 38 is formed of sheet metal and has upwardly flanged front and rear edges 40 and ll terminating in laterally extending lips 42 and I3. The sheet .of metal is of sufficient length to extend across the guide tracks I and I1, and has downwardly extending flanges l4 and 45 to the inner faces of which are attached angles 48 and II, the angles being arranged so that the horizontal webs 48 thereof extend inwardly in downwardly spaced relation with the body portions of the sheet and enter the guide tracks between the upper and lower flanges. thereof as clearly shown in Fig. 2. The inner edges of the horizontal flanges of the angles terminate in downwardly extending lips I! to provide guides for the carriage relatively to the rollers 23. The forward ends of the angles project beyond the front flanges and are provided with substantially rectangular shaped openings 52 to engage the peripheries of the rollers 23 when the carriage is in retracted position, as later described.

The opposite ends of the angles project beyond the rear flange 45 and the horizontal leg portionsare notched, as at i i, to accommodate rollers 52 which are joumalled on studs 33 projecting inwardly 'of the vertical flanges of the angles so that the rollers 52 are adapted to engage the facing sides of the flanges l3 and 20 when the rollers are passed through the spaces 23, previously described, in which position the horizontal flanges of the angles are supported on the rollers 23.

Extending longitudinally of the carriage, intermediate the edge flanges l! and II, is a reinforcing channel 54 of substantially the same height as the edge flanges and which is secured to the body portion of the carriage by outwardly flanged feet 55. Mounted on the under side of the carriage, in registry with the guide channel 34, is' a bar having" a rearwardly.pro-

'jecting end I1 carrying a roller 31 mounted on a stud 59 and arranged so that the opposite sides of the roller are adapted to substantially engage the

flanges

35 and 30 of the guide channel. The opposite end of the bar is free of the carriage and forms a spring latch I, having an offset forming a stop shoulder II cooperating with a stop 62 that is spaced therefrom adistance substantially equal to the width of the flange 28, whereby the latch is adapted to drop over the flange 23 when the working topis in projected position, as shown in Fig. 5. The forward end of the bar terminates ina handle 03, by which the latch is'adapted to be released so that the working top may be moved from projecting position. Y v

The working top proper comprises the shell 39 having the full width of the cabinet section and includes a horizontal top 84, depending ends I and ii coextensive with thefront and back depth of the shell and located in the plane of the outer faces of theside members 8 and the sides of the cabinet section, and a front or apron 31. The depending sides substantially conform in depth to the spacing section i so as to, in effect, form a continuation thereof, as shown in Fig. 1. They are, however, adapted to move under the projecting portion 'of the cooking top when in retracted position whereby the front or apron i1 aligns with the front of the range. Inserted between the shell and the carriage is a sheet of insulating material 68 that is retained in position by' fastening devices 83 extending through openings III in the carriage,

registering openings H in the insulation and into threaded nuts 12 carried by brackets 13 that are attached to the under face of the top .portion of the shield, as shown in Fig. 7, I

In applying the assembled working top to the range, the rollers 52, which are joumalled on the projecting rear ends of the

angles

48 and 41, are passed through the spaces 26 so that they enter between the upper andlower flanges of the guide tracks. The forward edge of the cooking top assembly is then lowered to substantially horizontal alignment with the range so that the horizontal flanges of the angles rest upon the rollers 23. In this position the roller 31 engages between the side flanges of the guide channel and the working top may be moved into retracted position so that the rear portion thereof engages under the projecting portion of. the cooking top and the front apron 61 aligns with the front of the range, as clearly shown in Fig. 3. In this position, the openings 50 engage the rollers 23 to, in effect, form friction latches for retaining the working top in its retracted posion.

when the working top is to be projected for use, the sides thereof are engaged by the hands so that it may be withdrawn forwardly of the projecting portion of the cooking top. The handle portion 63 of the latch bar 56 bears directly upon, the flange 23'so that when the top is in completely projected position, the latch drops thereover'with the offset portion 8| engaging the front edge of theflxed flange and the stop 6 engaging the rear edge to retain the working top in projected position. retained from retractive movement and is securely supported so that various cooking preparations may be performed on the working top. The top, when projected, also forms a guard to prevent too close approach relatively to the flame of the cooking top. The top also serves as a guard to prevent children from reaching the burner top or playing with the burner controls.

The offset relationship of the center roller 31 relatively to the other rollers facilitates movement of the working top and at the same time maintains parallel relationship so as to prevent binding of the carriage with respect to the guide tracks. The top may be returned to retracted position by raising on the handle portion of the latch so that the oiIset thereof may'slide' over the top of the fixed flange, after which sufficient pressure is applied to move the carriage rearwardly of the tracks. 7 7

In case it is desired, to remove theworking top, this may be readily effected bywithdrawing the top and holding the latch lever so that it is prevented from engaging the fixed flange at the front of the range. The top may then be withdrawn to the point where the rollers carried thereby are in position to be withdrawn through In this position the top is the openings at the forward ends of the guide tracks. When thus removed, the top of the range, including the working top, is accessible for cleaning and therefore may be readily kept in sanitary condition.

Mounting of the enamel shell on the top of the carriage provides a rigid construction and the insulation deadens the sound when articles are placed on the working top. The insulation also resists yielding movement of the top under pressure applied thereto.
