7 Claims (o1. 454584) Our invention relates to devices for protecting .office machines, such as typewriters, adding machines, accounting machines, calculating niaohines, and other similar machines, from the dust .5 when not in use.

1 ,Ihe objects of our invention are to. provide such a covenfirst, as. will be out of. sight and out of the way when it is not in use; second, as will take up very little room when not-in use;

third, which may be incorporated .as a partnof the machine or which may be attached to :a machine; fourth, which folds up automaticallywhen removed from operative position and which rolls up automatically and smoothly out of the way, when so folded; and fifth, which is simple to make, easy. to attach to a machine and to operate, and effective in use.

W e attain these and other obj ects,.such as appear from the description, by the devics'mechcompanying drawings, in which- Fig. 1 is a side elevation of a machine showing our invention applied thereto and rolled away to permit the free use of the machine; Fig. 2 is .a similar View showing our improved cover being unrolled from said stowed away cpndition; 3

is a similar View showing our improved cover fully applied to cover the machine; Fig. 4 is a front elevation {of the machinewhenso covered; 7 Fig. 5 is a side elevation, partly in section, showing the container for our improved cover; Fig. :6 is a rear elevation of one end thereof; Fig. fllisxa plan view of our improved cover before it is folded and applied to the roller, and showing the lines on which it is to be folded and sewed; Fig. 8 is aside elevation of our improved cover folded-and'sewed and applied to spring roller; Fig. 9 is a top plan View thereof; and Fig. 10 is a diagrammatic end elevation of our improved cover to show the manner and form of its folding.

Similar numerals of reference refer to similar parts throughout the several views.

Our invention is illustrated as applied to a typewriter but it is to be understood that, with appropriate changes in dimensions, the cover may be applied to any desired device or machine, such as those indicated in the above general statement. Also, the form illustrated is that in which the cover and its container are secured to such a machine as already made, but it is to be understood that the roller on which the cover is mounted may be permanently incorporated within the frame of the machine, the cover emerging therefrom through a suitable slot, or the container may be a permanent part of the machine.

anisms and arrangements illustrated in theac fl now to the drawings, the machine frame I is mounted on suitable cushioned legs 2. A cvertica'lfastener plate 3, having horizontal fastoning armed, which ane adapted to be secured in place between the frame 4 and the said legs 2, extends across the machine 4. Thisplate .3 is substantially as long as the width of the machine frame land is positioned at the rear thereof on a level with the base thereof. A vertical carrier plate 5 is secured to the fastening plate 8 :bymeans of suitable bolts ii. In some cases the oonstmmtion of the frame 1 is such that the carrier plate 5 may be. secured directly to the rear of the said frame 4 using the fastening plate Theoarnier plate 55 is provided with two cars .1, one at each end, extending rearwardly therefnom andslmpcd substantially as shown in the dnawines. ears i are provided with suit able :beaaing lmies 18 adapted to receive and support the end trunnions of a suitable spring roller ,9. The hollow spring roller 9 is not illustrated in detail since-it .of the welieknown type and of the usual construction, having one trunnion ioumaled in one ear 1 and having an helical spring H) mountedlwithin it, said spring being attached at its inner end to the said roller 19 and at its ntherend to the other trunnion, which is held from rotation by the other ear 1. of .the container. The seller is also provided with suitable holding dogs, not shown, mounted in the usual ,wayto prevent its undesired rotation. Aaneta'l cover 1! lies on theloutsideledges .of the .ears 1 and is provided with suitable clips 12 adapted to hold it in place and to stiffen the ears '1 laterally, said clips the removal .of the cover M when desired. The cover li ieanes .a. space 13 between the frame I and theupper edgelof the metal comer, forming aslot through which our improved machine compasses to or from the spring-roller 9, on which it is rolled.

' Our improved typewriter cover is made of suitable cloth or fabric and is cut substantially as shown in Fig. 7. The central part 14, between the two lines 15, is slightly narrower than the. width of the machine to be covered, and is pro vided with a tail IQ, of the same width, which is adapted to be secured to the outside of the spring roller 9. A pleat is formed on each side of the central part l4 by creases made on the corresponding lines I! and H3.v The side panels I9 extend from the folds H! to the side folds 29, a distance substantially equal to one-half of the width of the central part l4, and are adapted to lie immediately under the said central part 14 (Fig. 10). The edge Zl'is about the same width top 'of the ears of the container.

as either of the two elements of the pleats. The width of the pleat elements between the creases I5 and I1, and I1 and I8 will vary withthe particular machine to be covered. 7

When the cloth has been cut and. folded as 'above described, the rear or inner end is sewed byagrowfof stitching on'the line 22, thus securing all the parts together in front of the tail l6. Similarly the front or outer end of the cover is turned over a rod 23 'andis stitched on the line 24, thus securing the rod to the cover and securing all the parts together along the front line. 'The rod 23 islonger than the width of the central part M of the cover and extendslout on each side.

thereof when sewed in place. 7 u 7 The operation of our improved machine cover is briefly as follows-It is noted that in Fig. 1

roller 9 catches and prevents its being further drawn back; then therod 23 is carried forward over the machine and allowed torest in front thereof; then the sides, which lie under the cover thusplaced, are drawn out laterally and draped over the parts of the machine extendingout beyond the sides of the frame I; .In this position it will be noted that, though the

side strips

20 and 2| have a shorter distance to pass from the rear to the, front, they actually passabout as far as the central part 14 because the

sewing seams

22 and 24 attach said part to the center part I, and while the said center part I4 passes over the top of'the machine, the said sides pass from the center of the rear around the side to thecenter of the front of the machine.

.Now, when it is desired'to stow the cover away, all that it is necessary to do isto raise the stiffening rod .23 vertically and the sides of the cover will pull away from the machine and, at once, and automatically, will assume their proper positions for being rolled (Fig. 2) and then, by pulling upward on the said rod 23 to release the roller dog, the entire cover will 'be withdrawn into the container by beingrolled neatly on the said spring roller. We have found that, by folding the cover in the manner above described, it will pass on to the roller without buncliing or unnecessary wrinkling. r

It is to be understood that many variations may be made in the embodiment of our invention without departing from the spirit thereof as outlined in the appended claims.-

Having described our invention, what we claim and desire to secure by Letters Patent, is:-

1. A roll cover for machines comprising a spring roller mounted on the, rear of the machine; a cloth cover secured to said spring roller and of width greater than the width of said roller and folded in on itself between its ends, said folds being secured together at its ends; and stiffening means extending across the outer end of said cover.

2. A roll cover for machines as .set forth in 2 claim 1, wherein said cloth coveris pleated at its folded edges.

3. A roll cover for machines comprising a spring roller mounted on the rear of the mapanels, with pleats folded between the side panels and the center portion; and stiffening means extending across the outer end of said cover.

4. A roll cover for machines as set forth in claim 3, wherein the side panels extend from the pleats substantially to the center of the center part of thecover, and on the underside thereof.

5. A roll cover for machines as set forth in claim 3, wherein saidcloth cover is of a width greater than twice the width of said roller, and the side panels extend from the pleats substan tially to the center of the center part of thecover, and on the under side thereof.

6. 'A roll cover for machines, comprising a carrier plate secured to the rear of the machine; a pair of ears extending rearward fromthe ends of said carrier plate; a metal cover mounted on said ears and forming therewith a container; a spring roller mounted between said ears and in the container; a cloth cover secured to said spring roller and of a width greater than the width of said roll: er and folded in on itself between its ends, said 'ends being sewed in folded condition; and a rod sewed into the outer end of said cover and extending beyond its folded edges.

'7. A roll cover for machines, comprising a fastener plate secured to the rear legs of the machine; a carrier plate secured to said fastener plate; a pair of cars extending rearward from the ends of said carrier plate; a metal cover mounted on said ears and forming therewith a container; a spring roller mounted between said ears and in the container; a cloth cover for the machine secured to said spring roller and of width great er than twice the width of said roller andfolded in on itself between its ends, said ends being sewed in folded condition; and a rod sewed into the outer end of said cover and extending beyond its folded edges.
