TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented July 1,913.

Original application filed August 22, 1910, SeriallNo. 578,457. Dividedand this application filed May 4,

T o all whom it may concern Be it known that I, CHARLES H. VOGEL, a

subject of the King of England, residing in it in letter-feeding' direction, and also to en` able the carriage to be returned easily and readily -from any point. Y

I attach a rod with an armature to the typewriter carriage. The rod extends in the direction of travel of the carriage, and the armature is guided along a table or shelf "upon which are mounted electro-magnets preferably arrangedin two rows, between which the armature moves. Connected with vthe armature, I provide a rocker having two so as to close circuits through the electro-' magnets in the rear or in advance of the traveling armature; holds in contact lwith the table, that contact shoe which is remote from the typewriter carriage, so that the action of the magnets is normally to advance the armature' and the carriage in the letter-feeding direction, that is. from right to left, exerting a tension which advances the carriage through a lettcr-'space whenever thecarriage escapement lisoperated. By depressing a carriage-return key, the position of. the rocker is reversed, so as 'to depress thecontact shoe which is upon the lside of the armature adjacent to the carriage. The niagnetsto the left of the armature then become inactive,

'and the magnets immediately to the rightVA become energized' and draw the armatureY toward the right; as the armature advances, the active contact shoe slides along the table i and closes other contacts more in advance of the armature; in thisway, the armature will A spring normally Serial VNo. 624,918.

of the carriage. In the accompanying drawings, Figure 1 is a plan of the carriage-feeding and returnbe drawn along, so as to complete the return ing device, showing part of the carriage to which it is attached, parts of the returning device being broken away. Fig. 2 is a longitudinal section through the feeding and returning device, taken on .the line 2 2 of F ig. l. Fig. 3 is a part elevation and cross section through-the table which supports the electro-magnets of the feeding and returning device.

A carriage 1 is controlledin'its movement from right to left by an escapement 1a. At

a suit-able point, such as the left-hand rear 'portion of.` the carriage, I attach a rod 3,

.which extends in the direction of travel of ythe carriage, and on the end of this rod is carried an armature 5, in the form of a block having a guide spline '19, which runs in a groove 20 in the upper 'face of atable or` shelf 4. The armature 5 travels between two rows of electrdmagnets C, which are connected bymeans of conductors 15, to mains-16; said mains being in circuit with a battery 17 or other source o t' current. rl`he armature 5 is provided with a laterally project-ing stem 11, carrying a 'rocker 10 inthe form of a bow, as shown in Fig. 2, the end of the bow llying adjacent to the table, and being provided with pivotedeontact slices 13 and 22. A spring 21 normally holds the shoe 22 on v,the face of the table, so that it may bridge ,one or more pairs of contacts 14, with whiclrthe Aconductors 15 connect. In this way, a circuit is normally closed through one or more pairs of magnets at the left of the armature 5, the opposite magnets of the two rows being connected by conductors 18 for this purpose.

On the upperside of the rocker 1 0, .a lug 12 is provided, and as the armature travels to and fro, this lugtravels along-under a bar 9, which extends longitudinally of the table, and is supported on arms 9a pivoted at 4* on posts 4, which extend rearwardly from the table 4C. At a convenient point, a ret-urn key 7 rests upon the bar 9, preferA 4ably at the right end thereof, which is ad` jacent to the carriage 1. This key is piro' ally supported at 8, as shown in Fig. and when it is depressed, it depresses the bar 9 which contacts with lug l2, and rotates the `25 ture.

o thereby reversed, and theI armature moves toward the right to return the carriage.

n account ofthe spring 21, the shoe w22v is normally held on the table, so that two or Y more electro-magnets atthe left of the arma-I 5 ture are normally active, and normally exert a tensiofi on the carriage, coperating with the e.i;..ipement.1a to give the carriage its" feeding movement.

Having thus described my invention,` I
