SAMUEL L. OONDE, OF ROCKFORD, ILLINOIS.

TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 514,911, dated February 20, 1894.

Application filed April 7, 1893. Serial No. 469,483. (No model.) i

To all whom it may concern.-

Be it known that I, SAMUEL L. come, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

The object of this invention is to impart avertical, oscillatory movement to the platen.

This invention relates to that class of typewriters, in'which each type bar is provided with a series of type and in which the platen is made movable in order that all the type may leave their imprint in the same line.

In the accompanying drawings: Figure 1 is a plan view of the typewriting machine showing my improvements. Fig. 2 is a vertical lengthwise section. Fig. 3 is a front elevation, the base frame being in section.

In the drawings I have only shown such portions of a typewriter with which my improvements are closely connected and consists of a base 1 from the rear end of which rise brackets 2, connected by a rod 3.

The platen carriage is formed by the base 4 and ends 5, from the under side of the base depend lugs 6. A sliding engagement is formed between the carriage and the rod 3,

by means of the truck 7. The platen 8 is mounted in the carriage in the usual manner. To the upper ends of the brackets 2 are pivoted arms 9, which extend forward and a rod 10 connects these arms forming a swinging bail. Y I

From the front lower face of the paper carriage depend lugs 11, supporting rollers 12. These rollers are located upon the upper surface of the rod 10, which, in connection with the truck 7, form the sliding engagement between the paper carriage and the main supporting frame. A red 13 has a pivotal connection with the brackets 2 and supports arms 14, carrying rollers 15, located under the arms 9. p

The shifting key consists of the levers 19 and. 16, the latter having a pivotal connection with the rear end of the main frame and a spring 17 holds them in their elevated position, a cross rod 18 limiting their upward movement. The front ends of these lovers are connected by a finger strip or key proper 19.

A connection is formed between the levers 16 and rod 13 by the links 20, its upper end of each link engaging a hook 21, extending from the rear face of the rod 13 and its lower end provided with a turn buckle 22. By depressing the finger strip the rod 13 will be oscillated in its engagement with the main frame, which will cause the arms 9 carrying rollers 15 to assume a higher plane, which will elevate the bail frame and. consequently elevate the paper carriage and platen by reason of the hinge connection between the paper carriage and the main frame.

Adjustable hooks 23 are connected with the main frame, having their upper ends overlying the upper face of the arms 9, which will limit the upward movement of the paper carriage. By means of this arrangement the platen is shifted so as to present the same printing surface to the different type upon the same type bar.

It will be noticed that I impart a vertical oscillatory movement to the platen for the purpose of printing the capitals and small letters upon the same line, while the machines heretofore constructed have employed either a horizontal or a vertical shift to the platen.

I claim as my invention- 1. In a typewriting machine the combination of a frame, a carriage, a platen supported thereby, a series of type bars each carrying a series of type, and a key for imparting a vertical oscillatory movement to the platen.

2. In a typewriting machine, the combination of a paper carriage havinga pivotal connection at its rear, a pivoted bar extending across the machine supporting the front end of the carriage, a key exerting its force upon the pivoted bar imparting a vertical oscillatory movement to the platen and type bars, each provided with a series of type.

3. In a type writing machine, the combination of a platen having a pivotal connection at its rear, a rock shaft carrying arms with rollers at their free ends and a key for rocking the shaft, thereby raising the platen.
