Divided and this application November 2, 1940, Serial No. 363,976

Claims.

This application is a division of my application Serial No. 187,578, filed January 29, 1938 and patented Nov. 5, 1940 as Patent 2,220,708, that was a continuation in part of my application Serial No. 649,910 filed January 3, 1933.

In these earlier applications, I described and claimed the combination of a strip of check blanks, a strip of transfer medium such as carbon paper, and a strip of cash book blanks, spirally rolled together to form a typewriter supply roll to be mounted on a typewriter, whereby checks can be written or filled in on a typewriter, copies of the checks can be made on the cash book blank strips and many required cash book entries relating to the transactions can be made on the same cash book blanks with the carbon copies.

The present application is based on the typewriter supply roll and the means for mounting it on a typewriter, and one object of the invention is to provide a novel and improved means for mounting a continuous form supply roll on a typewriter or the like whereby the continuous form can be progressively unrolled from the supply roll and typewritten as desired.

Another object is to provide a mechanism for typewriting continuous forms that shall comprise in combination with the typewriter carriage having a platen and horizontal bar parallel with the platen, a roll comprising a core having a continuous form strip wound thereon and a trunnion at each end thereof, and novel and improved brackets for rotatably and removably mounting the supply roll on said horizontal bar of the typewriter carriage.

A further object is to provide a novel and improved supply roll for continuous forms that shall comprise a tubular core having a continuous strip wound thereon, and a novel and improved trunnion plate secured to each end of the core for mounting the roll in a bracket support, so that the roll and end plates can be easily and quickly assembled and disassembled for removably mounting the roll on a typewriter carriage and interchanging difierent supply rolls.

Other objects, advantages and results of the invention will appear from the following description in conjunction with the accompanying drawing in which:

Figure 1 is a transverse sectional schematic illustration of a mechanism for typewriting continuous forms embodying my invention, and

Figure 2 is a longitudinal sectional view on the line 22 of Figure 1.

The typewriter supply roll A comprises a tubular core I of suitable material such as cardboard on which one or more continuous form strips 2 are spirally wound. An end plate 3 is removably attached to each end of the core to form a flange for the core, said plate having a spring element 4 secured centrally on one side of the plate and comprising a pair of spring arms to removably frictionally fit into the end of the core. Preferably the spring element is U-shaped and has its base attached to the end plate. Each plate also has at its side opposite the spring element 4 a trunnion 5 for revolubly mounting the roll A on a support. With this construction, the end plates easily and quickly can be inserted into and withdrawn from the core, so that the end plates may be interchanged with different rolls of continuous forms. It will also be observed that the spring arms 40 are approximately fiat in cross-section and their longitudinal edges will bite into the inner surface of the core so as to prevent relative rotation of the core and end plates.

The support for the roll comprises a bracket B including a U-shaped section 6 the arms 1 of which have notches I8 to separably receive the trunnions 5. The base of the section 6 has a pair of tubular legs 9 each to separably frictionally fit over a post ii) that has a bifurcated foot H to straddle the tabulator bar l2 of the carriage l3 of a known typewriter C. This bar [2 is horizontal and arranged parallel to the platen l4 that is also mounted on the typewriter carriage C. A screw I5 passes through the bifurcation of the foot ll beneath the bar l2, and the post I0 is screw-threaded at l6 through the foot to abut the bar [2 and tightly clamp the foot on the bar.

In the use of the invention, the bracket B is secured on the typewriter carriage C and the roll A is mounted on the bracket B with its axis parallel to the axis of the platen Id of the typewriter, as shown in the drawing. Then the free end of the continuous form strip 2 is slipped between the platen and the presser rollers IT in the usual manner, and the strip is unrolled from the roll A by rotation of the platen as is usual in feeding paper in a typewriter.

It Will be observed that the posts M can be easily and quickly adjusted on the bar l2 to conform to the spacing of the tubular legs 9 on the section 6 of the bracket B, and the nice frictional fit of the tubular legs over the posts will positively hold the bracket against displacement but at the same time the bracket can be easily and quickly applied to and lifted from the posts. Accordingly, the application and removal of the bracket from the typewriter carriage can be easily and quickly accomplished by a relatively unskilled operator, although ordinarily after the posts and bracket have once been fitted upon a typewriter, they may remain permanently in position because the roll A may be conveniently removed from the bracket when there is no need for the continuous form strip, or when it is desired to get the roll out of the way, for example, to permit closing of the top of a desk in which the typewriter is mounted.

Many modifications and changesin the details of construction of the mechanism will occur to those skilled in the art as within the 'scope'and spirit of the invention.

Having thus described my invention, what I claim is:

1. In a mechanism of the character described, the combination with a horizontal support bar, of a roll comprising a core having a continuous form strip wound thereon and a trunnion at each end thereof, a bracket comprising a U-shaped section each arm of which has a notch to removably and rotatably receive one of said trunnions, a pair of tubular legs secured to the base of said U-shaped section, a pair' of posts each to separably slidably fit into one of said tubular legs, a bifurcated foot for each post to straddle said horizontal bar, and a screw passing through the bifurcation of each foot beneath said bar, each said post being screw-threaded through its foot to abut said bar at the side opposite said screw for tightly clamping said foot on said bar.

2. In mechanism of the character described, the combination with a horizontal support bar, of a roll comprising a tubular core having a continuous form strip wound thereon, an end plate frictionally removably fitted into each end of the roll and having a trunnion, a bracket comprising a U-shaped section each arm of which has a notch to removably and rotatably receive one of said trunnions, a pair of tubular legs secured" 'to the base of said U-shaped section, a pair of posts each to separably slidably fit into one of said tubular legs, a bifurcated foot for each post to straddle said support bar, and a screw passing through the bifurcation of each foot beneath said bar, each said post being screw-threaded through its foot to abut said bar at the side opposite said screw for tightly clamping said foot on said bar.

3. In mechanism of the character described, the combination with a horizontal support bar, of a roll comprising a core having a continuous form strip wound thereon and a trunnion at each end thereof, a bracket including a main section having spaced arms each with a notch to removably and rotatably receive one of said trunnions, a pair of posts each having a bifurcated foot to straddle said support bar, a screw passing through the bifurcation of each foot beneath said bar, each said post being screw- I threaded 'in'its foot to abut said bar at the side opposite said screw, and means for separably connecting said'main section to said posts.

4. In mechanism of the character described for supporting on a horizontal support bar, a roll of paper having bearing elements to cooperate with a support, the combination of a bracket including 'a main section having spaced arms formed with means to rotatably receive said bearing elements of said roll, independent posts separably secured to said support bar for individual adjustmentlongitudinally thereof, and means on said bracket to frictionally and .separably telescopically .engage each post and arranged in predetermined relation to each other for removably mounting said bracket on said support bar.

5. In mechanism of the character described for supporting on a horizontal support bar a roll of paper having bearing elements to cooperate with a'support, the combination of a bracket including a -main section having spaced arms each ofwhich'has a bearing element to cooperate with one of said bearing elements on said roll for supporting "the roll in said bracket, a

pair of separate andin'dependent posts each inabut said bar at the side opposite said member,

and means on said bracket to separably engage said posts for mounting the bracket on said support bar.
