TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent'No. 415,530, dated November 19, 1889.

Application filed October 11, 1886. Serial No. 215,911. (No model.)

To 6056 whom it may concern:

Be it known that I, GODFREY I-I. LASAR, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Type Writing 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 top view of myimproved machine. Fig. 2 is a side elevation. Fig. 3 is a vertical transverse section taken on line 3 3,

Fig. 2, looking in the direction of the arrows.

Fig. 4 is a vertical longitudinal section taken on line 4 at, Fig. 1, looking in the direction of the arrows. Fig. 5 is a detail view showing the tumbler-bars which limit or regulate the movement of the key-levers. Fig. 6 is a top view of same. Figs.7 and 8 are enlarged de tail views illustrating the escapement and part of the rack. Fig. 9 is a section taken on line 9 9, Fig. 7, looking in the direction of the arrows, the dogs of the rack being in their upper position. Fig. 10 is a similar view taken on line l0 10, Fig. 8, looking in the direction of the arrows, showing the dogs in their lower position.

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 base; B, the key-levers; G, the carriage, and D the type-bar frame of the machine. The key-levers are pivoted to the base at one end by a rod or bar B passing therethrough and supported by standards B secured to the base.

B is the escapcment-frame, pivoted on the rod 13 and having a rod or bar 13 at its front end that passes under all the key-levers. The rear end of the frame has a lug B through which passes a pin 13, extending upwardly from the base A. The pin has a head 13 on its upper end, and between the head and the frame is placed a spring B that acts to sustain the frame in its upper position.

The escapement-frame is provided at the sides with lugs 13 having recesses 13 Extending over the lugs and adapted to bear thereon is the spacer-frame B having a finger piece or key B, by which it is depressed. The spacer-frame is supported by a frame 13 (to which it is rigidly secured,) pivoted on the rod B outside the escapement-frame, and connected by means of a log 13 with a pin B secured to the base A, having a head B and a spring B between the log and its head. The spacer-frame "may be secured to its supporting-frame by means of screws or rivets B The finger-piece of the spacerframe is located at the rear of the bank of keys, so as to be in a more convenient position, and extends entirely across the type-key levers. r

The carriage in this machine is preferably constructed and supported as in my applications Serial No. 215,904 and Serial No. 318,042, and reference is made to those applications for a description of the carriage shown in this application.

The escapeinent F in this application is made similar to that shown and described in my application Serial No. 318,042, and to that application reference is made for an under- 7 standing of this part of the machine; but in this application the fixed dog, that moves in a vertical line when the escapement is operated, is held from lateral movement in its normal position by a spring G, surrounding the pintle G of the dog. The purpose of this spring is to hold the dog from horizontal movement when in use for spacing and the carriage is advancing, but at the same time permit of its yielding or being moved horizontally out of engagement with p the rack to allow the carriage to be moved back for a fresh line, or for other object.

The escapementdogs F in this case are connected by a rod or'bar F to the rod B of the frame B so that they are operated each time a key-lever B or the spacer-frame B is operated. And when it is desired to throw the dogs entirely out of engagement with the rack of the carriage to allow the carriage to bemoved either back or forth without printing, the dogs are both moved vertically out of engagement with the rack by a key-lever Y, having a key Y, the key-lever when depressed coining against a projection Y on one of the lot lugs B and by depressing the frame B lowers the dogs, as stated.

I represents the type-bars, each bar having an upper and a lowercase type secured thereto. \Vhen a lower-case letter is to be printed, projections I on the rear ends of the bars come against a plate H and stop the movement of the bars just as the lower-case type I reach the roller of the carriage. If an upper-case letter is to be printed, the plate H is pulled down, so as not to be struck by the projections I, and then the upper-case type I will be brought over the roller of the carriage. The plate H is pulled down by being connected to the key-levers B by rods H. The keylevers B are pivoted to the bar or rod B, pass into the recesses B when depressed, and are provided with a finger-piece B in front of the bank of keys.

The type-bars are thrown forward by rods L, connected thereto at their upper ends and to blocks L at their lower ends, the block being pivoted in openings in a segment L in the same manner, preferably, as the type-bars are pivoted to the segment in my application Serial No. 215,907, and the blocks are connected to the key-levers B in this apmentioned.

key-levers the bars are drawn back and the key-levers lifted by springs L, connecting the rods L to the segment L (see Fig. 4,) assisted by the frame B their normal position without their inner ends coming in contact with and interfering with half of the bars are allowed to recede farther than the others, as shown in Fig. 1. This means consists of a ring D, resting upon the frame D and held in place by screws D connecting it to posts D extending upward from the segment L the posts also serving to hold and guide the rods H by having lugs D, through which the rods pass. (See Figs. 1 and 2.) The screws D pass through slots D in the ring D. The ring D has notches D opposite each alternate rod L of the typebars, and the rods that enter these notches carry their type-bars back farther than the other type-bars, the rods of all of the alternate type-bars coming against the frame D, beyond which the notches D extend. Thus, all the alternate rods coming against the same support D, some of the notches D may be deeper than others without any effect 011 the movement of the type-bars being caused thereby, thus avoiding the necessity of being careful to get all of the notches D the same depth.

When a machine is first put together, care should be takenthat the frame D be adjusted far enough forward for all of the rods L that enter the notches to come against it; or, in other words, the frame must be placed far enough forward to be in line with the notch or notches of the least depth, and no attention need be paid to the other notches. The adjustment of the frame is allowed by the slots D through which the screws D pass, as stated. Only one of the rods L is shown in Fig. 4.

. The type are inked by a movable pad M, located under them when in their normal position, (see Fig. 4,) and the pad may be moved up against the type by a key-lever M, on which it is supported by a link M the keylever being provided with a key M by depressing which the pad is moved up against the type. The pad is guided by sleeves M thereon, fitting over rods or pins M on the frame D. (See Figs; 2 and 4.)

\Vhen the type-bars have been moved to bring the type into printing position, they are struck by a hammer N to produce the printing or impression. The hammer is pivoted at N to a frame N and is connected bya rod or bar N to the inner end N 4 of a lever-frame N pivoted at N to standards N projecting upward from the baseA of the machine. Secured to the outer ends of the frame N is a rock-bar N connected by links N to a similar rock-bar N secured to the base A by arms N by which it is supported. The bar BI is pivoted to the frame N at N and the bar N is pivoted to the arms N at N This pivoting of the bars allows them to be turned from the position shown in Fig. 4

. to the position shown in Fig. 5, and as To allow all the type-bars to come back to the upper surfaces or faces of the rock-bars are farther from the pivot-points N and N than the inner faces it will be seen that when the rock-bars are turned into the position shown in Fig. 5 (when the inner faces will be brought uppermost and the upper faces will be turned outward) there will be a greater distance between the key-levers and the rock-bars than there is when the rockbars are in the position shown in Fig. 4. The object of this is to permit of a greater movement of the key-levers B when the upper-case type are to be brought into printing position. The rock-bar N acts to limit the downward movement of thekey-levers B, and when in the position shown in Fig. 4 permits the keys to be moved just far enough to bring the lower-case type into printing position. Now, when an upper-case letter is to be printed the key-levers B are first operated to depress the plate H, (as already described,) and as these key-levers are operated the rock-bar N is turned from the position shown in Fig. 4 to the position shown in Fig. 5 through means of its being connected by links N to the key-levers B thus allowing the keylevers B to be moved the necessary additional distance. As the rock-bar N is turned the rock-bar N is also turned through means of the described connection, so that the keylevers B do not come against the rock-bar N so soon as when in its other position, thus giving time for the type-bars to be moved to bring the upper-case type into printing position before the hammer is operated. IVhen the rock-bars have been thus moved from the position shown in Fig. 4 to the position shown in Fig. 5, they are returned to their normal posit-ion by a spring N coiled around a pin N on one of the arms N (see Figs. 4 and 6,) the pin entering the rock-bar N and this turning of the rock-bars back elevates the key-levers B through means of the connect ing-links N It will be seen that the key-levers B are sustained in normal position by the links N, blocks N arms N and springs N The carriage-roller is turned for a new line in this application by a lever arrangement, such as is shown in my application Serial No. 215,904, and the carriage is run back for a new line by means of a rock-shaft O, journaled in boxes 0, secured to the base A and connected by means of a rod or pitman O and a crank or lever O to the bell-crank lever 0 that turns the rollers of the carriage, as described in my application Serial No. 215,904. The crank O is secured to the shaft 0, as shown in Figs. 2 and 3, and by rocking the shaft it will be seen that the carriage will be run back. The shaft is rocked or turned by means of a handle P, pivoted to the shaft at P, and in moving the carriage back the handle P is moved in a vertical plane in the arc of a circle.

I disclaim any invention in the combination, with the type-bars, of key-levers and connections, substantially as described, between the key-levers and the bars for operating the bars, stop, block, and bars to which the stop is connected, provided with a key for operating the stop, as shown and described.
