Application filed larch 10, 1925. Serial No. 14,878. w

This invention relates generally to ma'-- containing a number of layers of work-sheets is drawn over a rear guide-rail and is led over a carbon-holder mounted on the carriage, the plies of work-webs being leaved with carbon-sheets carried y sa1d holder. The web and the interleaved carbonsheets are drawn forwardly around the platen and past the printing point as the work-web is being typed and line-spaced. Then the platen is straightened out in line with the web and the carbon-carriage is re turned to its rearward position to co-operate with a new portion of the web; then the typed form 1s cut off against a knife at t e delivery side of the platen, andthe operation of typing another set of similar forms is again repeated. The invention is also useful in connection with other varieties of manifolding typewriters.

It is sometimes desired to type a different form, and, in such cases, it is the practice to withdraw the web from. the machine to gether with its corresponding carbon-holder,

' and place both the web and the carbonholder in its corresponding box. This avoids the delay of reassembling the carbons between the plies of the web, especially when using the type of carbon-carriage dlsclosed in the atent to Fortin, No. 1,237,319, granted ugust 21, 1917.

According to the present invention, the

machine is then moved to another section of the desk-top corresponding to the position of another bin in which the desired form is stored, so that another carbon-holder may be fastened to the carriage, and the web to be t ped inserted around the platen of the mac ine.

There may be two or three bins side by side under the desk-top, from any one of which the work may be taken. Each bin, moreover, may be double, as shown in the atent to J. A. B. Smith, No. 1,358,033, of

ovember 9, 1920.

One of the features. of this invention is that a desk having a flat top of any kind may be used provided that the same is wide enough to allow the machine to be moved therealong to the different positions corresponding to the positions of the boxes in a lower shelf of the desk.

inter- Another feature is that the standard machine ma be used with little or no alteration thereof, it being only necessary to. remove the rubber feet and to attach the wheels to the frame by means of screws fitting the tapped holes into which the feet are normally screwed.

Still another feature is the ease and convemence with which this device may be handled.

Furthermore, this device adapts itself to be cheaply manufactured and quickly attached to the existing machines without in any way altering the equipment used, as in many cases .it ma be desired to increase the number of di erent forms used on the same machine.

In order to facilitate the placing of the typewriting machine in front of the corresponding bin in the desk, there are provided four rubber wheels operatively mounted under the frame of the machine and fastened thereto, instead of the ordinary rubber feet usually found in this type of a machine. The wheels are provided with means whereby the same may be rendered operative or ino erat ve, that is to say, the may be clampe stat onary while the mac ine is in use, or they may be allowed to rotate freely when the machlne is to be moved from one position to another.

Other features and advantages will heremafter appear.

In the accompanying drawings,

Figured is a rear view in elevation of a desk having a typewriting' machine of the fan-fold type placed thereon, and showing a plurality of web-boxes placed upon a lower shelf of said desk.

Figure 2 is a cross-sectional view in elevation on the line 22 of Figure 1.

Figure 3 is a cross-sectional view of one of the wheels showing the means for attaching the same to the frame of the. machine.

Figure 4 is a perspective view of the two front wheels mounted upon an ada ter plate, and shows means whereby the w eels may be rendered ineffective.

A table or desk is provided comprising standards 10 and a top 11, upon which stands an Underwood continuous billing typewriting machine. This machine comprises a main frame 12 and a rearward extension 13, upon which extension travels a carbon-carcarbon-sheets carried by said holder.

riage 14, forming part of the typewritercarriage. A web 15, comprising a number of layers of work-sheets, is drawn over a rear guide-rail 16, and is led over a carbonholder 17 mounted on the carriage 14, the plies of the work-web being interleaved v vliltlh e webs and interleaved carbon-sheets are drawn forwardly around the platen 18 of the machine and past the printin point indicated by the type-bar 19. T e carboncarriage and the web are drawn forwardly as a form is" typed on the web, and then the carbon-carriage is returned to its rearward position to co-operate with a new portion of the web, and the typed form is cut off against a knife. The process is then repeated to type another set of similar forms.

According to one feature of this invention, it is sometimes desired to remove one of the forms from the machine and substitute another one thereof. To this end there is provided a shelf 20, beneath the top of the 'desk and supported by the standards 10, on

which there may be placed a plurality of web containers or boxes 21 having a rear opening through which the fan-folded webs may be unfolded and drawn out of the boxes as needed. When not in use, the webs are left idle in the boxes, and the corresponding carbon-holder may also be placed in the box upon the web as shown in Figure 2. The boxes comprise bottom and side walls respectively numbered 22 and 23, and are laid upon the shelf '20. There may be provided any number of boxes as required, six being shown in the drawings grouped in setsof two, one over the other.

In order that the machine may be positioned in front of the box containing the particular form of web to be used, and in order to render the operation simple and convenient, the frame of the machine is provided with wheels 24 operatively mounted beneath the frame 12. Said wheels are mounted on angular plates 25, which are in turn fastened to the frame 12 by means of screws 26, designed to fit the tapped holes into which the feet are screwed, so that the feet may be taken off the machine and the wheels attached thereto.

The wheels 24. are revolubly mounted on studs 27, which are fast to the angular plates 25, by means of nuts 28, screwing into the threaded portion 29 of the studs 27. The plates comprise the two sides or wings of the angular section, a horizontal wing 30 in which the holes 31 are pierced in a position corresponding to the tapped holes in' the frame 12, and a vertical wing 32 which carries the studs 27 The four'rubber-wheels 24 are provided to facilitate the shifting of the machine from one side to the other of the desk, in a position in front of the box from which it is desired to withdraw the form. It is obviously necessary to provide means whereby the wheels ma be rendered ineffective during the operatlon of the machine; otherwise the machine would be moved out of place when spacing the carriage. 'To this end there is provided a lock whereby the two front wheels may be either rendered operative or inoperative by simply swinging a handle 33' either in a clockwise or a counterclockwise direction. The clamping means illustrated in the drawings comprise a threaded portion 34 at the end of the stud 27 a washer 35 to increase the frictional'surface on the hub of the wheels 24, and a nut 36 screwing on the threaded portion 34. The handle 33 forms an integral part of the nut 36, and serves as a means for either loosening the wheels or binding them in a fixed position. The two rear wheels are always operative, there being provided no means for binding them in a fixed osition, and, instead of the binding nut and handle provided in the two front wheels, there are provided cotter-pins 37 to hold the Wheels in place.

Another feature relates to the structure of the wheels themselves which comprise a hard rubber core 38 and an outer soft rubber tire 39, the function of which is to stick to the table when the wheels are locked, thereby preventing the machine from creeping away when being operated. The core of the wheels is made of hard rubber, to pro- 7 vide a resilient hold for the clamp and at the same time to render the wheels stiff enough to withstand the weight of the ma chine.

To prevent the machine from sliding off the table, there is provided a cross-bar 40 at the ends of the desk-top; thus the travel of the machine is limited within the width of the desk-top. The bars are made the full depth of the desk-top to which they are fast to interpose the wheels 24 and to check their rolling on the table.

Variations may be resorted-to within the scope of the invention, and portions of the improvements maybe used without others. Having thus described my invention, I claim:
