TYPE-WRITING MACHINE.

To all whom it may concern:

Beit known that I, HARRY MIKKELSEN, a citizen of the United States, residing in Chlcago, in the county of Cook and State of Illinois, have invented certam new and useful Improvements in Type-Writing Machines, of which the following is a specification.

This invention relates to collating boards provided upon the paper carriages of typewriting machines having revoluble platens. It is customary to collate the work-sheets 1n various relative positions upon the board,, and after such collating, to carry the sheets from the board around the platen to the printing position, without disturblng the relative arrangement of the sheets.

One of the objects of the present invention is to improve the means for carrylng the collated sheets around the platen and mai ntaining them in their proper relationship. To this end, I provide at the ends of the platen flexible endless bands, each of which has a series of sheet-impaling studs, and each of which also has a series of holes to fit studs or sprockets on the platen itself. By this means, the bands are caused to travel in unison, and moreover any liability of the bands slipping or creeping edgewise upon the platen is avoided by their engagement with the platen studs or sprockets. The other ends of the endless bands run over an idle roll, which may also be providedwith sprockets to prevent edgewise creeping of either band at this point; it being desirable to maintain the bands with the impaling studs thereon in exact relationship to each other at all times. The bands are kept taut independently of each other by springs, one at each end of the idle roll over which the bands run.

Another feature of the invention resides in the means for attaching the board-supporting frame to a supplemental carriage. The arms which extend down from the' board-supporting frame are :made extensible and connected by universal joints to plates, and the plates are fixed to the supplemental carriage. By reason of the extensibility of the arms and the adjustability of the plates, necessity of accurate and careful manufacture and fitting is avoided.

Another feature of the invention is the provision of a wire or thin support upon which to hang the carbon sheets. This wire Specification of Letters Patent.

extends across from one ofthe stud-bands to sheets, and especially when removing some of the work-sheets others.

Other features inafter appear.

In the accompanying drawings, Figure 1 is a front perspective view of a part of a paper carriage of an Underwood front-strike typewriting machine, showing the sheet board applied thereto and illustrating my improvements. Fig. 2 is a sectional View to illustrate the universal joint for attaching the sheet board to the supplemental carriage. Fig. 3 is a sectional side elevation of an Underwood typewriter carriage with my improvements applied thereto. Fig. 4c is a front elevation to illustrate the connection of the collating device to the typewriter carriage. Type-bars l strike against the front side of a cylindrical platen 2, which is revolubly mounted bymeans of an axle 3 in a carriage 4, which is propelled by a spring (not shown) in the usual manner and controlled by the usual escapement mechanism, which is operated by the keys that actuate the typears 1, as is well known.

The sheets to be collated are laid upon a board 5, which may extend upwardly and rearwardly from the platen; the side margins of the sheets overlying endless flexible thin metal bands 6, one at each end of the platen 2; the bands looping around the platen and extending up along the collating board, and at their upper portions running over an idle roll or pulley 7. The perforatlons in the side margins of the work-sheets engage studs 8, which are arranged in rows on the opposite bands 6, preferably along their inner edges. The bands may be separated so as to expose sufiicient space on the platen between them to form the desired writing surface, although the bands may, if desired, be of very thin metal and hug closely .to the platen, and themselves afford a suitable backing for the paper to receive the type impressions.

The studs 8 in one and replacing them by and advantages will herestuds 8 on the other band; and in order to preserve this relationhand must bear a fixed wardly and rearwardly from sheets platen,

synchronously with the other,

studs or sprock ets 9, which fit into perforations 10, each band having a line of these perforations ex preferably along its outer edge. of studs or sprockets it follows that one band 6 must travel relationship -be on one band and those on always preserved. may fit so closely in the holes 10 of the band tending for its entire length, Both sets 9 being fixed to the and hence the impaling studs 8, the other band is Said sprockets 9 also tween the as to prevent sidewise creeping of the latter along the platen; and,

if desired, the idle roll 7 may also be provided with similar sprockets 11 for the same purpose.

The collating board 5, which supports the flexible bands which to collate the sheets, by upper and lower cross bars are bent down table on may be supported 12, 13, which at their opposite ends at 1 1 6 and serves as a and connected by rods 15 which extend upthe typewriter carriage 4:, being connected thereto at their lower ends by screws 16. a The idle'roll 7 may be carried upon extensions or rods 18, which telescope into the ends of the rods 15, and are constantly pressed outward by springs 18*, so as to keep a tension on the stud bands 6.

From the rods 15 extend rearwardly arms 19 to a carriage 20, which may be in the form of a grooved carried by upp which are held arms 2 1 extendi slide, running on balls er and lower tracks 21, 22, by brackets 23, carried upon ng upwardly and rearwardly from the typewriter framing 2 1. The arms 19 may be sufiiciently separated to permit the bands 6 to pass between them. Each arm 19 may be composed of two portions,

one of them, 25, telescoping into the other,

and carrying at its, rear end a ball 26,

which forms part of a ball-and-socket joint; the other part thereof being carried upon a plate 27, which-is attached by screws 28 to the supplementary carriage 20. The extensible part 25 by a set screw of the arm19 may be secured 29, Fig. 1. The extensible support .25 permits truing of the sheet board relatively to the platen,

at 26 permits the plate 27 to be turned to fit the front joint and the universal surface of'the carriage 20,

notwithstanding the shifting or adjustment of the part 25 relatively to 19. The rods or upper ends by may extensions 18 may also be joined at their a cross bar 17. The rods 18 also carry an apron 30 to guide the sheets around the idle roll 7 and down hehind the collating board, to the usual guideplate or paper to the printing shelf 31, which conducts the beneath and up in front of the platen point.

A support 32 upon which to hang carbon sheets, tending across is herein shown as a wire or rod exfrom one to the other of the vfrom the platen,
