Similar characters ofreierence are employed in all of the hereinabove described views to indicate corresponding parts.

Referring now to said drawings, the ref erencecharacter 20 indicates a complete casing made up of a plurality of separable umts or sections interconnected together one above another. Said separable units or sea tions comprise a bottom or base section 21, a top section '22 and intermediate sections 23". All of the sections. are provided w th open forward ends, and top walls 24. W th the exception of the bottom or base section 21, the remaining sections are open at their bottom or under sides, so that when as sembled together the top wall of one section will form or provide the bottom wall of the next section above, thus'eifecting a saving in material and labor in manufacturing the device. The said bottom or base section 21 is provided with a bottom wall 25. The several sections 21, 22 and 23 are each provided at their corner portions with exteriorly disposed vertical socket members 26, which are open endwise, so that when said sections are assembled together, the sockets of corresponding corner portions will aline themselves vertically one with another. The

' means for securing said separable sections together in operative assembled relation, comprise, main, couplin bars 27 which are inserted through the a nod sockets of the three lower sections at their respectiie corner portions, and auxiliary coupling bars 27 The lower ends oft-said main coupling bars may'be bent or doubled upon themselves to provide foot pieces 28, arranged to project downwardly from the bottom or base section, having connected therewith, at their bases, a covering 29 of soft or non-abrasive material, which will protect a desk or other surface upon which the device is placed against being scratched or marred by the device. The upper ends'of said coupling bars 27 are provided with upwardly extending coupling tongues 30 which are alined with the right hand longitudinal edge of each coupling bar, and which are provided with an undercut or oblique inner edge, preferably as shown in Figures 3 and 4. Said auxiliary coupling bars 27' are of a length suitable to interconnect adjoining sections or units, and the same are provided at their upper ends with upwardly extending coupling tongues 31, which are also alined with the right hand longitudinal edge of each coupling bar 27', and which arealso provided with an undercut or oblique inner edge as shown, while at their lower ends are provided downwardly extending cou pling tongues 32, which are alined with the left hand longitudinal edge of each coupling ascents bar 27', and which are provided with undercut or oblique inner ed as shown. In assembling the above escribed coupling bars with the sections or units of the'casing, the coupling bars 27 are inserted upwardly through the respective socket members 26 of the bottom section 21, and then an intermediate section 23 is arranged toengage its socket members 26 over the coupling bars 27, and is then pushed down into place upon said bottom section 21. Auxiliary coupling bars 27' are them inserted in the socket I members 26 of the next section or unit of the casing so that their lower ends project downwardly and outwardly therefrom. The coupling tongues 32 of said auxiliary coupling bars 27, thus arranged, are thereupon almed with and interlocked'with the coupling tongues 30 of the coupling bars 27, and the said next section or unit of the casing is thereupon pushed down into place upon the section or unit-below, so that the interlocked coupling tongues 32 and 30 are entered in the socket members 26, to be thereby retained against lateralseparation, while the bars 27 and 27 are retained against longitudinal separation by the dovetailed or interlocked opposed undercut or oblique inner edges of said respective coupling tongues. In a similar manner additional intermediate sections or units of the casing together with a top section 22, may be assembled with additional coupling bars 27', the coupling tongues 31 and 32 of adjoining coupling bars 27' being interlocked andembraced by the socket members 26 in a similar manner, all as illustrated more particularly in Figure 3. From the above, it will be understood, that the casing may be composed of any desired number of units or sections, within reasonable limits, according to the number of sheets and intermediate carbons it is desired to collate.

The top section 22 is provided at its longitudinal and rear side edges with an upstanding flange 33, thus providing an open receiving compartment or receptacle for used carbon sheets. In order to prevent dislodgement, by air currents or draughts, of the used carbon sheets which may be deposited within said receiving compartment or receptacle, the same may be provided with a protector leaf or cover sheet 34 which is suite ly connected by a hinge connection 35 at the rear end of the receptacle, so that the same may be swung upwardly to permit the deposit or removal of carbon sheets.

Connected pivotally with the top section 22 in a suitable manner is a combined lockable closure and copy rest, the same comprising a main body 36 having a horizontal flange 37 at its pivoted end. Telescopically or slidably associated with the free end of said main body 36 is an extension member 38, the free end of which is provided with as a closure to cover the open ends of the assembled units or sections of the casing, the main bod 36 is swung downwardly to extend over t e said open ends of some of the sections and units, and the extension member 38 is pulled or slid downward and outward to cover the open ends of the remaining sections or units, in which position the loop 39' is alined with the loop 40 so that the hasp' of a padlock 41 may be passed therethrough, and the latter locked to hold the closure in operative position, thus guarding; the contents of .the sections or units against unauthorized removal when fthe'device is not in use, all as shown in Flgure 1. When the arrangement is disposed-in open position and ready to serve as a copy rest,

the padlock 41 being removed, the extension member is moved inward relative to the main body 36, and the latter is turned upwardly. to the'position shown in Figure 2,

in which position it is erected in rearwardly inclined position above said top section 22, with its flanges 37 in position to engage and support, in conjunction with the mam body 36, a book, papers to be copied or the like.

When the units or sections making up the casing are in assembled relation to each other, they are adapted to provide a plurality of compartments, disposed one above the other. Each compartment is adapted to hold a pile of sheets differing in character of purpose from the sheets in the other compartments. For example, in the illustration of my invention shown in the accompanying drawings, there are five compartments. The upper compartment contains a pile of letterheads 42 or the like, the next or -second compartment below contains a pile of carbon sheets 43, the next or third compartment bYlOW contains a pile of copy sheets 44, the next or fourth compartment below contains a pile of carbon sheets 45, and the bottom compartment contains a pile of copy sheets 46. Each compartment is provided with a sheet ejecting means, and means for simultaneously op erating said ejecting means is also provided, so that upon manipulation of the latter, one sheet is ejected from each compartment, and the several ejected sheets are thus brought together, so that the ends of the same may be grasped to withdraw the sheets entirely from the device in a desiredready collated relation, i. c. with the carbon sheets respectively disposed intermediate the letter head and copy sheets all ready for introducing into a typewriter machine. In handling the piles of sheets for introduction into the compartments, and particularly the thin carbon sheets, it is of advantage to have the sheets supported by a comparatively nonflexible supporter tray, and to this end removable bottom or supporting trays 47 i an provided, having at their forward edges tabs 48, serving as finger pieces for withdrawing the same. The said trays maybe provided with steps 49, if desired, such as shown in Figures 17 and 18, which serve to. position half-sheets in the compartments in proper same, and in proper relation to the ejec'to'r I means of the compartments.

wall of each section or unit, adjacent to the I forward end thereof, are a pair of longitudinally disposed laterally spaced apart arallel track members or slideways 50. T ese track members or slideways are preferably relation to the forward open ends of the I formed by striking the same out of the body of said top wall, so as to form downwardly spaced or ofi-set lips or ways 51. The track members or slideways thus formed are ar- "ranged in substantially central position intermediate the sides of the units or sections. Mounted on the track members or slideways, for longitudinal reciprocable movement thereon, is a carriage member 52, having at its sides lips 53 for slidably engaging over the lips or ways 51'. Said carriage member 52 is provided, intermediate its ends, with a pair of depending laterally'extendingand opposed bearing portions 54, in which is mounted a transverse pintle 54'. Pivotally mounted on said pintle 54' is a longitudinally'disposed impeller bar 55. Removably connected with the inner or rearward extremity of said impeller bar 55 is an impeller block 56, to which is fixed a downwardly and forwardly obliquely projecting impeller point 57. Said impeller block 56 is split at its ends so as to receive the bifurcated end 58 of said impeller bar 55, thus frictionally attaching said impeller block 56 to said impeller bar. Said impeller bar is provided with an arm 59 which projects forwardly from the pivotal connection of said impeller bar with said pintle 54'. It is preferable to render said impeller bar readily removable from said pintle 54, sothat the same may be easily detached from operative relation to the carriage member 52, and withdrawn from the unit or section with which it cooperates, thus permitting replace-. ments of worn or damaged impeller points 57 when desired. To this end said arm 59 is doubled back upon itself to provide a portion 60 having adjacent to its free end a semi-cylindrical member 61 corresponding with a similar semi-cylindrical .member 62 provided in said main body of the impeller bar 55, which together rovide bearing portions adapted to strad dle said pintle 54. The free end of said arm 59 possesses an up turned guide-lip 63. By means of the arrangement thus provided, a longitudinal outward pull upon' the impeller bar 55 will tend to separate themembers 6'1 and 62 due to the. tensional yielding of the portion 60,

I 59, thereby preventing any undue lateral play of the impeller bar 55. Connected with the top Wall of each section, and preferably pressed out of the same, is a downwardly and forwardly inclined lift cam 65. Said lift cam is positioned forward of the carriage member 52, and in such location that movement of the carriage member will carry the arm 59 of the impeller bar 55 into and out of engagement therewith, so that the said impeller bar 55 will be rocked on its pivotal connection to lower or raise its rear end. Normally the arm 59 is engaged with said lift cam 65, when the carriage member 52 occupies its normal forwardly disposed position, whereby said arm 59 is depressed and the rear end of the impeller bar 55 is lifted or raised to hold the impeller point 57 in normally raised and inoperative position. Pressed downwardly out of the top wall of each unit or section are a pair of deflecting lugs 66, which are disposed respectively on either side of said impeller bar 55 ad acent to the rearward end of the latter. These deflecting lugs 66 are downwardly and rearwardly inclined, and serve to deflect piles of paper, when the same are being inserted into a compartment, from. accidentally engaging the raised impeller point 57, to the possible detriment of both the paper and said impeller point.

The means for .actuating the carriage member 52 comprises a transmission lever 67 pivotally mounted on the underside of the top wallv of the sections or units, the inner end of said lever 67 having a bifurcated portion 68 which straddles a pin 69 fixed to the carriage member 52, thus operatively coupling the lever with the latter. The forward end 70 of said lever 67 projects outwardly through a slot 7 0 provided in a side wall of the sections or units, so that said forward or free end of said lever -is exteriorly disposed at a side of the unit or section with which it is connected. A

pull spring 71, suitably anchored within each of the units or sections, is connected with the forward portion of said lever 67,

to hold the same in and return the same operatively engages said lever 67, when the actuating lever 72 is swung downwardly. The actuating lever 72 of the top section or unit is provided with an upwardly projecting extension or tongue 74 upon the free end of which is fixed' a finger piece or knob 75. The actuating levers 72 of the sections below the top section are each provided with upwardly projecting extensions or tongues 76, the upper free ends of which are provided with a vertical slot'77, dividing said ends into two arms. One of said arms is bent downwardly and outwardly to provide a finger-piece 78 for manipulating the actuating lever 72 to which it is attached independently of any operation of the actuating levers 72 of the sections or units above, and the other arm 79 is inwardly offset and obliquely inclined to extend upwardly beneath the actuating lever 72 of the section above. A means is provided for transmitting the o erative movement of each actuating lever 2 to the next adjacent actuating lever below, so that the ejecting means of all sections or units may be simultaneously actuated, said coupling or transmitting means being of such a nature, however, that the same will not interfere with the actuation of selected groups of actuating levers 72 less than the whole number, since the coupling or transmitting means, will not effect or actuate any movement of actuating levers 72 above the one operated. Said coupling or transmitting means comprises a coupling lug 80 having a bifurcated end 81 which is transversely engaged to seat. itself in the slot 77 of the extension or tongue 7 6, with its bifurcated end 81 straddling the latter, and its upper end transversely disposed in engagement with the underside of the actuating lever 72 next above. so that downward movement of one actuating lever 72 will produce a downward thrust upon said coupling lug 80 which will be transmitted to the actuating lever 72 below to produce a simultaneously operated move ment thereof, and so on down through the series of said actuating levers.

In operating the apparatus, if it is desired to eject a sheet from each compartment, the finger-piece or knob is pushed downwardly, whereby the actuating levers 7 2 are all operated to in turn simultaneously raoaaae actuate the ejector devices of each section or unit. If it is desired, for example, to operate only the ejector devices of the two lowermost sections or units, to secure an extra carbon and copy sheet, the finger-piece 78 of the next to lowermost section or unit is actuated or pressed down, thereby operating only the actuating lever 72 of that section and that of the section below, while the actuating lever 72 of the sections above, and consequently'the ejector devices actuated thereby, remain inactive.

llhe operation of the ejector devices with which each compartment is equipped is as follows When the actuator lever 72 of a given compartment swings downward, its pushcam 73 thrusts against the adjacent transmission lever 67, turning the same on its pivot, and thereby transmitting to the carriage member 52 a rearward sliding move ment As the carriage is thus moved rearward, the arm 59of the impeller bar 55 is retracted from engagement with the lift cam 65, thus permitting the rear end of the impeller bar 55 to drop down until its impeller point 57 engages the paper or top sheet which occurs shortly before the carriage member completes its rearward movement. In completing its rearward movement the carriage member causes the lowered impeller bar 55 to trail the impeller point 57 rearwardly, over the surface of the top sheet of paper in the compartment, see Figure 8. As the pressure actuating the downward swing of the said actuating lever 72 is released, the spring 71 reverses the movement of the tranmission lever 67 and associated parts, so that the carriage member moves forward, thus causing the forwardly moved impeller bar to train the impeller point 57 forwardly. Since the impeller point is forwardly and downwardly inclined, ittends, on such forward movement to engage positively the top sheet, and thereby impels the same to accompany the forward movement, until the carriage member 52, in approaching its forward initial position, carries the arm 59 in position to ride up the inclined lift cam 65, thereby depressing said arm 59 and lifting the impeller bar 55 to remove the impeller point 57 from the paper, see Figure 9. By repeating the movement of the actuating lever 72, that is by oscillating the same a few times, the ejector means is caused to repeat the above movements, so that quick step by step outward movements of the top sheets of the piles within the compartments are caused, to project said sheets outwardly from the open ends of the latter, where they may be grasped by the operator, in their properly collated mutual relation, and entirely withdrawn from the compartments. I Since it is desirable to produce 'a succession of impelling movements of the ejector means of the several compartments, where by the sheets are ejected by a series of short step by step impulses, ll' find it convenient to provide a means for guiding the operator in the manipulation of the actuating levers 72, so that the latter may be each oscillated through only a partial arc of its stroke, whereby the carriage 52, after it has moved rearwardly far enough to relieve the impeller bar 55 from raised position, will be reciprocated only through the zone of operative contact of the impeller point 57 with the paper. To this end I provide a means shown in Figure 16 of the drawings, the same comprising a forwardly projecting extension piece 82, which is fixed to the upper actuating lever 72 to move therewith, and which has its free end outwardly off-set to cross a flexible member 83 which is vertically disposed, and fixed by one end to the upper section or unit. Said member 83 sesses an outwardly projected nosing 84 having inclined upper and lower sides, and the spring member 83 is yieldable inwardly. The initial downward stroke of the upper actuating lever 72 carries the extension piece 82 downwardly past said nosing 84, the member 83 yielding to its passage. When the downward stroke of the actuating levers 72 are completed, the operatorv allows the same to come back until, the extension piece 82 engages the nosing 84, whereupon the operator again pushes downwardly on the actuating levers 72, repeating these movements, and thereby producing a series of short reciprocations of the ejector mechanism, until the sheets have been ejected far enough out of the compartments, whereupon the operator fully releases the actuating levers 72 for complete. return to normal initial positions, thus permitting the extension piece 82 to pass upwardly by the nosing 84, which again yields to such passage, until the parts resume normal initial positions.

It may sometime be desirable to render the ejector means of certain compartments inoperative, while the others are permitted to function. To this end I provide, in con nection with each carriage member 52, a means for holding out of service position the impeller bar 55 of such carriage member, this means consisting of an adjustable stopmember 85 pivotally mounted on the carriage member, and positioned so as to be swung at will into position over the arm 59 of said impeller bar 55, whereby as the carriage member is moved rearwardly and the arm 59 disengaged from the lift cam it will engage said stop-member 85, and be retained thereby against movement, so that the rearward end of the impeller-bar-will be retained in lifted or inoperative position during the movement of the carria e member. Said stop-member 85 is provi ed with posrojecting fingerfpiece" 86 an outwarl v 'ghtly beyond the mouth oi.

which exten s the compartmenawhen the carriage mom-5 understood from the above description,

without further reca itulation, except to say that the device bein formed from so arable sections or units, t e same may ily be enlarged by additional sections or units, to provide for a desired increase of the number of sheets to be operated upon and collated in the desired redetermined relation oneto another. It wi l alsobeunderstood that the device is not limited for use in con nection with typewriter papers, but may be em loyed for collating sheets or sheet materlals of other characters and for other purposes. a
