Specification of Letters Patent.

Patented. June 16, 1908.

Application filed September 12, 1907. Serial No. 392,421.

citizen of the United States, residing in Hartford, in the-county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Type- Writing Machines, of which the following is a specification.

This invention relates to paper-severing attachments for typewriting machines, and the object of the invention is to provide inexpensive, simplified and improved means that may be readily applied to existing machines for cutting or severing sheets from a paper web.

A cutting-blade is secured at its ends to brackets or plates which are adjustably mounted upon the laten-frame ends, the blade lying along an in front of the platen.

Either end of the blade may be adjusted independently of the other end towards or away from the platen, so that the blade may be readily and acc'uratelypositioned and do effective work.

In the accompanying drawings, Figure 1 is a top view of a typewriter platen frame with' my improved device applied thereto. Fig. 2 is a sectional end view of Fig. 1, and shows the paper web feeding around the platen.

Fig. 3 1s a perspective view of the blade and brackets,

The platen l is rotatably mounted in the platenrame ends 2, connected by a paper-' table 3, all of the construction usual in the well known Underwood typewriter. A bracket or late 4, preferably of sheet metal, ,is mounte upon each end 2 of the platen frame,-and arms 5 extend inwardly toward the platen, and downwardly inside of the platen frame ends, as at 6. Secured by screws 6 to the downwardly extending parts 6 are rigid arms 7. A cutting-blade 8 of some suitable hardened metal is secured at close to the platen.

each end by means of rivets 9 to the arms 7. The blade lies between the )lates 4, in front of the platen, and is incline to the latter.

The plates 4 are provided with slotslO, through which pass screws 11 for securing them to the platen-frame ends 2, and permit shifting of the said plates 4 backwardly and forwardly, together with the cutting-blade 8, towards and away. from the platen, thus permitting of the insertion of a sheet or sheets of paper of different thickness between the blade 9 and the platen 1. The plates 4 are shiftable one independently of the other.

The paper 14 passes from a roll 13 around the laten and up between the same and the cuttmg-blade. When a relatively thin paper is being used the cutting-blade 8 is set quite However, shouldit be desired to use a thicker sheet of paper, or a number of sheets of paper, the blade is set outwardly or away from the platen by loosen ing the screws 11 and shifting the plates forwardly. The blade is set above the place'where the types 16 strike the platen.

Having thus described my invention, I claim: v

An attachment for the platen frames of typewriting machines,.comprising a pair of brackets having slots for adjustable connection to the ends of the platen frame, each bracket having an arm to extend down i111 front of the platen, and a cutting blade to-ex- JOHN HUTCHINSON.
