ery important object of, I the inven en t en i'qe.: :;t -r qvidemix n slabpithe o e en: w tioned character, comprising novel means for firmly securingthe,renewable mixing surface in g position.
Other objects of the invention are to provide a mixing slab of the character described which will be comparatively simple in construction, strong, durable, highly efiicient and reliable in use, compact and which may be manufactured at low cost.
All of the foregoing and still further objects and advantages of the invention willbecome ap- .20 parent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate correspondin parts through the several views, and wherein:
Figure 1 is a top plan view of a mixing slab constructed in accordance with the present invention. v
Figure 2 is a view in side elevation of the device.
T Figure 3 is a top planview with parts omitted.
Figure 4 is a view in longitudinalsection, taken substantially on the line 4-4 of Figure 1.
Figure 5 is a cross-sectional view, taken substantially on the line- 5-5 of Figure 2.
Referring now to the drawings in detail, itwill be seen that the embodiment of the invention, which has been illustrated, comprises a frame of suitable material which is designated generally by reference numeral I, this frame being sub- 40 stantially rectangular in plan.
The frame I includes side and end members 2 and 3, respectively, the former having formed in one end portion angular slots 4 in which a roll of parchment paper 5 is rotatably mounted.
Journaled between the other end portions of the side members 2 is a roller 6 beneath which the parchment 5 passes. The adjacent end member 3 of the frame I has formed therein a slot I through which the parchment is drawn after 50 passing under the roller 6. A bar 8 on the frame I parallels the slot I and provides a tear-01f edge for the parchment.
Mounted on the side members 2, between the end members 3, is a panel 9. A spring I0 beneath 55 means s-ensaged; wi h the. are; frr riie-l tionally securing said roll against. idle. rotatio o e on. hermal 9. s a p ir t ransv rs ly' elongated plates I I whichare spacedfromjhe end members 3.

the outer edges of thevbars I2 are'blades I5, said blades being engageable in grooves it which are provided therefor in the opposed edges of the end members 3 for firmly-securing the parchment 5 in position.
A crankshaft I1 is journaled transversely on the frame I between the plates II. Bars I8 connect the bars I2 to the throws I9 of the crankshaft I1 for retraction thereby against the tension of the coil springs l4. The end portions of the crankshaft I! are formed to provide operat-. lllg handles 20. Grooves or channels 2Iv in the upper faces of the plates H accommodate the connecting bars I8.
Mounted on the plates H and extending over I the slidable bars I2 is a slab 22 of suitable material. portions of the slab 22. This is illustrated to advantage in Figure 4 of the drawings.
It is thought that the operation of the device will be readily apparent from a consideration of the foregoing. Briefly, the roll of parchment paper 5 is mounted for rotation in the closed ends of the angular slots 4. The strip or web constituting the renewable mixing surface of the device is then threaded upwardly between the adjacent bars I2 and end member 3.1 Of course, the crankshaft I1 is first turned to retract the bars I2. The parchment paper is carried forwardly across the slab 22 and inserted downwardly between the other bar I2 and the adjacent end member 3. The paper passes beneath the roller 6 and emerges from the frame I through the slot 1. The crankshaft I1 is then turned to. permit the coil springs I4 to project the bars I2 to operative or looking position, thus firmly securing the paper 5 in position on the slab 22. The device is now ready for use. After the device has been used and when a new mixing surface is desired, the shaft I! is turned to again retract the bars I2 against the tension of the springs I4, thus releasing the paper. The paper is then pulled forwardly through the slot 1 until The bars I2 are slidable beneath the end the used portion has been withdrawn and anew surface is in position on the slab 22. The used portion is then torn off on the blade or strip 8 and the bars l2 are again released to locking position. The device is now ready to be used again. The spring I frictionally keeps the paper taut while a new surface is being drawn into position.
It is believed that the many advantages of a mixing slab constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of.
parts may be resorted to which will fall within the scope of the invention as claimed.
What is claimed is: p
1. A mixing slab of the character described comprising a frame, a web supporting slab mounted on said frame, securing means' beneath each end portion of the slab said securing means being cooperable with the frame for releasably securing a web in position on said slab, and manually operable means for simultaneously releasing said securing means.
2. A mixing slab of the character described comprising a frame, including end members, a web supporting slab mounted onsaid-frame, and
means on the frame beneath the end portions of the slab and cooperable with the and members for releasably securing a web in position on the slab.
3. A mixing slab of the character described comprising a frame including end members, a web supporting slab mounted on the frame, bars slidable on the frame beneath the slab and cooperable with the end members for releasably securing a web in position on said slab, and means for actuating the bars to operative and inoperative position. i
4. A mixing slab comprising a frame, a panel mounted on the frame, plates mounted on the panel, a web supporting slab mounted on said plates, bars slidable between the slab and the panel and cooperable with the frame for releasably securing a web in position on said slab, a manually operable crankshaft rotatably mounted on the frame between the plates, and means operatively connecting the bars to said crankshaft f or, retraction thereby.
5. A mixing slab of the character described comprising a frame including side and end members, a panel mounted on the side members, a
pair of spaced plates mounted on said panel, a
web supporting slab mounted on the plates, bars slidable between the slab and the panel and co operable with the end members for releasably securing a web in position on said slab, pins on the bars slidably engaged in the plates, coil springs on the pins for urging the bars toward locking position, a crankshaft operable between the blades, and bars operatively connecting the first-named bars to the'crankshaft for retraction thereby.
