HENRY G. RAZALL, OF MILWAUKEE, VISOONSIN.

MOIST-PAN FOR COPYING-CLOTHS.

SPECIFICATION forming part of Letters Patent No. 439,896, dated November 4, 1890. Y

Application filed January 3 1890. Serial No. 335,765. (No model.)

To all whom, it may concern:

Be it known that I, HENRY G. RAZALL, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented cer tain new and useful Improvements in Moist- Pans for Copying-Cloths; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to moist -pans for copying-cloths 5 and it consists in certain peculiarities of construction and combination of parts to be hereinafter described with reference to the accompanying drawings, and subsequently claimed.

In the drawings, Figure 1 represents a vertical transverse section of one form of my invention; Fig. 2, a plan view of the same, with parts broken away; Fig. 3, a vertical transverse section of another form of said invention, and Fig. 4 is a detail elevation illustrating a hinge that forms part of my invention.

Referring by letter to the drawings, A represents a pan provided on one side with slotted lateral ears b for engagement with the horizontal portions c of right-angle hangers d, depending from the top B of a reservoircover, said ears and rod forming a hinge that permits of the reservoir-cover being swung back without regard to its elevation in the pan. In both forms of my invention the top B of the reservoir-cover is provided with an opening e, tapped to receive a stopper O, the latter serving as a handle for said cover.

Extending in from walls that depend from the top B of the reservoir-cover is a continuous flange f, and clamped between this ilange and a detachable frame g is a pad D,lcom posed of absorbent layers hand non-absorbent layers t', the latter being perforated at certain intervals. The pad shown comprises abottom layer of iannel or felt and alternate layers of blotting-paper and perforated oilboard, one of the latter being on top.

The pan A is of ordinary construction, being designed for the reception of copyingcloths E, and these cloths rest upon a sheet F of absorbent material.

In that form of my invention shown in Fig. l water is introduced into the reservoircover through the opening e in the top B, and per colates down through the layers composing the pad D to keep the copying-cloths E moistcned, said opening being closed by the stopper C, so as to permit of said cover being turned back on its hinge without spilling the water. In order to secure the proper distribution of Water in the pad, the non-absorbent layers i have the perforations therein so arranged that those in one break joints with the next. p

In that form of my invention shownbyFig. 3 the pad D is similar to what has been already described; but the stopper C for the opening e in the top B ofv the reservoincover is hollow and has its bottom provided with a bearing j for a screw-threaded rod G, that carries a conical valve k for-a corresponding opening m in the bottom of a receptacle H, the latter being secured to the under side of said top of the reservoir-cover.

In the latter form of my invention, the stopper O being run up out of the opening e in the top B of the reservoir-cover, water is poured into the receptacle II and said stopper returned to its normal position, the flow of the water from said receptacle being regulated by the adjustment of the valve k,where by just enough of said water is distributed to the pad D to keep the latter properly moistened after the absorbent layers thereof have been once thoroughly dampened.

In either form of my invention the pad is supplied with moisture for an indefinite time by one filling of the reservoir-cover, and this moisture is communicated to the copyingcloths E to keep the latter damp, the surplus moisture, if any, being absorbed by the sheet F, on which said cloths rest.

By the above description it will be seen that when a pad has become unfit for use it can be readily replaced.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A moist-pan cover that comprises a top provided with a water-inlet and depending walls, and an absorbent pad detachably connected to the walls of said cover to form a bottom for the lat-ter, substantially as set forth.

2. A moist-pan cover that comprises a top provided with a water-inlet and depending Walls, an absorbent pad detaohably connect connected to the flange to clamp the pad in ed to the Walls of-said cover to form a bottom place, substantial-1y as set forth. for thelatter, a receptacle depending from In testimony that I claim the foregoing I y l Said top beneath the Water-inlet, and a Valved have hereunto set my hand, at Milwaukee, in
