TYPE WRITING MAGHINE.

No. 445,152. Patented Jan. 27,1891.

PATENT OFFICE LOUIS EUGENE BAKER, OF SAN FRANCISCO, CALIFORNIA.

TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 445,152, dated January 27, 1891.

Application filed June 25, 1890. Serial No. 356,746. (No model.)

To all whom it may concern.-

Be it known that I, LOUIS EUGENE BAKER, a citizen of the United States, residing in the city and county of San Francisco, in the State of California, have invented a new and useful Improvement in Type-Vriting-Maehines, of which the following is a specification.

The object of my invention is to enable a person, when operating a type-writer and desiring to move the carriage for spacing letters or words, to do so quicker and more accurately and with better control of the movement of the carriage than is at present possible.

My invention is more particularly adapted to that class of type-writers commonly known as the Remington; but it is applicable to any style of type-writer possessing a similarly-arranged carriage and spacing-rack. I attain this object by means of the mechanism illustrated in the accompanying drawings, in which Figure 1 is a top plan of the carriage and spacing-rack frame. Fig. 2 is a view of the left-hand end of the carriage, showing my invention.

Si milar letters refer to similar parts throughout the several views.

A is a metal rod of suitable length and shape, and which is hung in the bearings C C, which bearings are attached by means of rivets or otherwise to the left-hand end of the carriageframe 1. One end of the rod A is turned up and terminates with a suitable finger-piece, as shown at I), and the other end of the rod is turned under the carriageframe at a suitable angle, and is so adjusted that the point of therod rests on top of the rod B at the point marked H in Fig. l.

B is another metal rod of suitable length and shape, one end of which is attached to the spacing-rack frame E by means of a nut, as shown, or by any other suitable method, and the other end of which rests under the point of the rod A, as shown at II in Fig. 1. The rod 13 is curved, as shown at M in Fig. 2, so that it is clear of the top of the carriagerod L.

O G are bearings supporting the rod A, which are attached to the carriage-frame I.

D is the finger-piece, previously described.

E is the spacing-rack frame.

F is the spacing-rack.

G are the spacing-dogs.

I is the carriage-frame.

J is the large paper-roller.

K is the feed-roller.

L is the carriage-rod on which the carriage is moved.

The spacingraek F has teeth on its lower side, which, in conjunction with the spacingdogs G, serve to hold the carriage at any de sired point.

\Vhen the finger-piece D is sufficiently depressed by means of the thumb or finger, the end of the rod A at the point marked H in Fig. 1 depresses the point of the rod B at that place, and this action causes the spacing-rack F, which is attached to the spacingrack frame E, to be lifted up and off the spacing-dogs G, and the carriage is then free and can be moved on the carriage-rod L to either the right or left side of the machine.

The spacing-rack frame E is so hung or hinged on the carriage-rod L as to permit the movement just described.

I do not limit myself to the exact form of the invention shown in the accompanying drawings, as the adjustment of the rods A and B with respect to each other may be somewhat different; or the end of the rod A terminating with the finger-piece D may be placed somewhat forward or backward of the point shown in the drawings. or it may be turned up inside of the carriage-frame near the point shown in Fig. 1.

Vhat I claim as my invention, and desire to secure by Letters Patent, is

In a type-writing machine, the combination of the sliding carriage, the tilting rack at the rear thereof provided with an arm, a lever independent of the line-feed lever, pivoted to the carriage and connecting with said arm and extending to or near the front of the carriage, and a finger-key for operating said lever, all substantially as herein set forth.

LOUIS EUGENE BAKER.
