TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 415,524, dated November 19, 1889. Application filed October 11,1886, Renewed July 19, 1889. Serial No. 318,042. (No model.)

To all whom it may concern:

Be it known that I, GODFREY II. LASAR, of the city of St. Louis,'in the State of Missouri, have invented a certain new and useful Improvement in Type IVriting Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which- Figure 1 is a rear elevation of the carriage and a transverse section through the key-levers of my improved machine. Fig. 2 is a top view of the carriage in the position shown in Fig. 1. Fig. 2 is a detail view showing a vertical transverse section on the line 2 2, Fig. 2. Fig. 3 is a front elevation of the carriage. Fig. 3 is a top view of the track or carriage-supporting frame. Fig. 4 is a vertical transverse section of the carriage and escapement on line 4 4, Fig. 6, enlarged, looking in Fig. 5 is a detail top view of the escapement enlarged. Fig. 6 is an enlarged rear view of the escapement. Fig. 7 is an enlarged perspective view of the dogs of the escapement. Fig. 8 is a top view of same. Fig. 9 is a section thereof on line 9 9, Fig. 8, looking in the direction of the arrows. Figs. 10 and 11 are enlarged end views of the carriage, Fig. 10 showing the paper shield or guard in normal position for printing and Fig. 11 showing it raised. Fig. 12 is an enlarged perspective view of one end of the carriage-rail. Fig. 13 is an enlarged perspective view of one of the sockets .of the track or carriage-supporting frame.

This invention relates to certain improvements in type-writers; and it consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring to the drawings, A represents the main frame, B the key-levers, and O the carriage, of the machine. The frame A is formed to receive the key-levers beneath it, as shown in Fig. 1, and beneath all the key-levers extends a rod or bar E, to which is connected an upwardly-extendin g bar or rod F, secured at its upper end to the dog G of the escapement, the dog having a lug G, perforated to receive a bolt G that connects it to the upmade in the form of a slot, so that the bolt G may be shifted back and forth therein to regulate the vertical movement of the dogs. The rod or bar F is made in two parts, the

adjacent ends of the two parts being slotted to receive a connecting-screw F. This allows of a lengthening or shortening of the rod or bar to regulate the movement of the dogs.

The dog G is pivoted to move vertically, and it is pivoted at G to a fixed arm' 11 of a pendent plated-I. So it will be seen that each time a key-lever B is operated or depressed the dog G will be pulled down into the position shown in. Fig. 9, and each time it is thus pulled down it is brought into engagement with a tooth of the rack C of the carriage.

Pivoted to the dog G at I is another dog.

I, which is arranged to move horizontally 011 its pivot, and, as it is secured to the dog G, it of course moves vertically therewith. \Vhen the dog G is in its upper position, the dog I engages the rack, and when the dogs are pulled down, as stated, the dog I is disengaged froin the rack and is moved into the position shown in Figs. 7 and 8 by a spring 1 so that when the dogs move up again the dogI will engage the next notch to the one last occupied by it and the carriage will be allowed to move forward the distance of one notch under the influence of the spring .I. The spring J is stronger than the spring 1 so that when the dogs rise the dog I is moved into line with the dog G by the movement of the carriage. The spring I is made so that it will throw the dog I into the position shown in Fig. 7 and no farther, as described, and at the same time it allows or permits the dog to be thrown around or out still farther when the carriage is run back to commence a new line. The dogs and spring J are secured to the plate H, dovetailed into projection A of the frame A, so that it can, when desired, be adjusted up or down by aset-screw M, the screw being held and working in lugs L M, secured to 'or formed upon the plate H and projection A, respectively. This construction I have described and shown in another application, Serial No. 215,904, filed October 11, 1886. The stem or arbor J, upon which the housing of the spring J turns, is held. from turning backward by a ratchet-wheel J and a pawl J (See Fig. 6.) By turning the wheel J 2 the spring J maybe tightened. The track or carriagesupporting frame T, to which the plate-pendant II is secured, or upon which it is formed, and by which it is supported on the main frame, and upon which the carriage moves or travels, is made of Iongitudinal front rail F, longitudinal central bar F and horizontal end bars or pieces T (see Fig. 3%) the end pieces projecting beyond the rear side of the central bar and having vertical extensions T formed upon or secured thereto attheir rear ends, the extensions having sockets T on their upper ends to receive the rear rail of bar C of the carriage, which moves back an d forth therein as the machine is operated. The rail or bar C has end flanges C and adjustable collars C, provided with set-screws 0"", the object of the collars being to regulate the movement of the carriage by adjusting them in or out, so that they will come against the extensions sooner or later, as desired. The object of the flanges is to limit the movement of the collars. The carriage has a front rail (1 (in addition to the rear rail 0 and secured to this rail C is a downwardly-extending arm C, (see Figs. 3 and 4,) having an inturned end C", that engages beneath the outer longitudinal piece T of the track-frame, and above and bearing upon the piece is a roller C journaled in arm C to reduce the friction between the arm and piece. This guides and supports the front part of the carriage.

The carriage is provided with an adjustable paper-guard N, made in two pieces N N the piece N being hinged or pivoted to the rail O of the carriage. The horizontal part N of the guard has an upturned inner edge N, which directs the paper upward under the'vertical part N of the guard. The direction in which the paper is inserted is shown by dotted lines, Fig. 4, it passing above the part N of the guard. The upper edge of the part N has a comb N hinged to it by a rod N and strips N, as shown, the action of which is to keep the paper down upon the roller. The comb may be turned from the operator or from the position shown in Figs. 2 and 4 out of the way of the type toward the rear of the machine into the position shown in Figs. lOand 11, after the paper is inserted, to permit the type to strike between the part N and the rod of the comb. The part N is adjusted to and from the roller of the carriage by turning it on the rail O for which it is provided with a lever 0 having a dog C", engaging ratchet-teeth C on one of the ends 0 of the carriage. The dog is held into engagement with the ratchet-teeth by a spring C secured in an opening or socket 0 of the lever. The dog has an arm 0 against which the spring bears, (see Fig. 4,) and this arm extends beyond the lever, so that by pressing thereon the dog may be disengaged from the ratchet-teeth to move the part N of the guard back from the roller of the carriage.

I claim as my invention 1. In a type-writer, in combination with the carriage and keys, the track-frame, adj ustable plate to which the track-frame is secured, horizontally-pivoted dog secured to said adjustable plate, spring-dog pivoted to the horizontally-pivoted dog, adjustable rod connected to last-mentioned dog, and rod or plate extending: beneath the keys of the ma chine and to which the adjustable rod is connected, substantially as and for the purpose set forth.
