TYPE-WRITING MACHINE.
SPECIFICATION forming part of Letters Patent No. 618,154, dated January 24, 1899.
riginal application filed lebrhary', 1897, Serial No, 622,407. Divided and application led January 24, 1898. Serial No. 667,703. Again divided and this application iiled October 7,1898. Serial No. 692,892. (No model.)
To all rtf/tom 'it may concern:
Beit known that I, GEORGE B WEBB, aciti- :cen of the United States, and a resident of lVestiield, in the county of Union and State of New Jersey, have in vented certain new and useful Improvements in Type-Vriting Machines, of which the following is a specification.
rThis case is a division of my application filed January 24, 1898, Serial No. 607,703, which latter is a divisional application of an application filed by me February 8, 1897, Serial No. 622,407, upon which Letters Patent No. 599,428 were issued on February 22, 1898, and relates to what is usually designated as the line-locking mechanism.
XVhile the main objects of my invention are to improve the construction and operation of what is known as the Remington No. 6 machine, it will, nevertheless, be understood that my improvements may be embodied in 'other forms or styles of machines.
My improvements consist in the various features of construction and combinations of devices, all as will be hereinafter more fully described, and particularly pointed out in the appended claims.
1n the accompanying drawings, Figure 1 is 1a rear view of the upper portion of the machine and showing more particularly the linelocking mechanism, the type -bars, key-1e vers, &c. being omitted to avoid complication and to enable the parts to be exhibited on a larger scale. Fig. 2 is a vertical section taken -at the line fr r of Fig. 1, and Fig. 3 is a plan view of the escapement-lookin g device, shown also in Figs. 1 and 2.
In the several views the same part will be found designated by the same numeral of reference.
At the rear side of the machine is a bar or rod 1, preferably rectangular in cross-section and pivotally secured at its ends in uprights or standards 2 on the top plate 3, one at the right and the other at the left hand side thereof. The pivots of the bar are made in the form of screws 4, having plain or un- -threaded ends 5, which enter plain holes in the ends of the bar or rod 1, the threaded portions screwing into threaded holes in the standards. This bar is formed on its rear side with a series of teeth 6, forming a series of intermediate notches, which may be equal in number to the teeth and notches of the carriage-feed rack 7 and the number of letter-spaces to which the carriage 8 is susceptible. The said bar is preferably graduated on its upper face or marked with numerals and lines to correspond with the number of notches or teeth thereon to facilitate the adjustment of the various devices movably mounted thereupon. ranged parallel with the path of travel of the carriage and has a slight endwise movement upon its pivots or centers for the purpose of locking the escapement mechanism and through it the printing mechanism at a predetermined time, as will beA presently described. Projecting downwardly from said rocking and endwise-moving bar is an arm 9, Y
which has a rearwardly-extended portion 10, that is slotted and engages With an upright projection 11, that slides in a slot in the top plate, the said projection being at the rear' end of a push-rod 12, which is suitably supported by bearings 13 under the top plate at the left-hand side and which projects slightly beyond the front end of said top plate, Where it is provided with a head or key-button 14. Surrounding said push-rod is a coiled spring 15 for returning it and the rocking bar 1, which .is connected thereto, as above explained.
The device which is provided to yarrest the forward movement of the carriage and at the same time by the power of the carriage-driving spring in the drum or holder. 16 to communicate endwise movement to the rocking bar 1 to lock the escapement mechanism performs also a function in the alarm or bell mechanism; but I shall describe more particularly the carriage` arresting and line-locking functions of the device, which generally is an oblong box-like structure 17, surrounding or embracing the sliding and rocking bar and provided interiorly with a spring tooth or dog (not shown) adapted to engage any of the notches on said bar. The said dog is formed The said bar is ar- 4 at one end of a lever pivoted Within the box and provided at its opposite end with a coiled spring adapted to maintain the dog in engagement with a notch on the rocking bar. A cam or eccentric (not shown) having a handle portion 23 is provided on orin said device 17 to enable the dog or detent to be withdrawn from the notch by either a right or left hand movement of the handpiece or lever, in order that the locking device, box, collar, or slide 17 may be adjusted or moved to any desired point on said bar. The detail construction and arrangement of the parts just described will be found' more fully illustrated in my aforesaid patent, No. 599,428. On the inner side preferably of said sliding box or device is mounted an index or pointer 25, which cooperates with the scale or grad nations on the upper side of said bar to facilitate the adjustment of the device. At the locality of said pointer is a lug or abutment 26, which is adapted to receive a projection 27 at the lower free end of a pendent arm or plate 28, secured on the rear end of a long pivot or rock-shaft arranged on the carriage at right angles to the locking-bar and provided with an arm 30, to which is attached an adjustable Weight 3l, that tends to maintain the said pendent plate or arm in a substantially vertical position. The said rock-shaft is supported at its outer or rearmost end in a lug 32 on the left-hand side of a rearwardly-projecting carriage-arm 33, which is forked at its extremity to embrace a collar 34, that slides on a guiding-rod 35, and the inner or forward end of said rock-shaft takes a bearing in the carriage 8. Surrounding said pivot or rock-shaft is a small coiled spring 36, attached at one end to a collar 37 on said shaft and at its other end to another collar 38, also on said shaft, and the spring at its latter end is prolonged or made straight, so that in the normal position of the pendent arm or plate 28 the extremity of the straight part of the spring bears against the said carriagearm 33. This spring acts against the weighted arm to move the pendent projection slightly forward when the carriage-arresting and linelocking mechanism is released. This mechanism is more fully illustrated in my aforesaid patent, No. 599,428.
On the under side of the rocking bar l at a point slightly on the right of the escapement mechanism is fixed an angular or L- shaped arm 45, which may be riveted to the said bar, as shown. The said arm projects rearwardly at right angles to the said bar and then laterally toward the left and parallel with said bar. The free end of the said arm is adapted to pass in front of an upward projection 47 at the rear edge of the escapementdog 48 when the said bar l is moved toward the left by reason of the contact of some moving part of or on the carriage with any of the collars which arrest the leftward movement of the carriage, and When thus moved the said arm prevents the dog holder or rocker from oscillating and the printing mechanism or type-bars connected thereto (through the universal bar'and the key-levers, as customary) from printing or being moved to an extent sufcient to enable the impression of the type on the paper in case the key-levers should be struck after the arm has passed in front of the projection 47. The escapement-dog 48 is attached to and forms a part of the usual rocker-arm 49, and which rocker also carries the pivoted or yielding escapem ent-dog 50,the rocker vibrating at right angles to the barl.
The locking of the escapement mechanism is effected in the following manner: Vhen the projection 27 on the pendent arm or plate 28 strikes the lug 26 on the box or collar on the bar l, the said bar is caused to move endwise toward the left for a short distance, as above explained, and in moving in this direction the arm 45 slides in front of the flange or projection 47 of the dog-rocker, and thus prevents the dog holder or rocker from vibrating forwardly, as shown by the dotted lines at Fig. 8. Vhen the carriage has been arrested and the dog-rocker locked,the carriage may either be returned for the beginning of a new line or the rocking bar may be tilted by means of the push-rod 12 to raise the locking-arm and depress the lug 26 and to enable the pendent projection 27 to step over the lug to permit more characters to be printed on the line. A small coiled spring 5l is employed to restore the rocking bar and arm 45 to their normal positions when the line- locking projections 26 and 27 are separated. The locking of the dog-rocker may be eifected at or during the rst half of the letter-space movement, the remaining half of the letter-space movement being permitted by reason of the capacity of the pendent projection 27 to yield under the superior power of the carriage-driving spring. On releasing the dog-rocker 49 by tilting the rocking bar l the latter is moved back toward the right by the spring 5l,and the pendent projection or contact 27 is vibrated slightly toward the left by its coiled spring 36, thereby insuring the pendent projection riding over the top of the lug or contact 26 on the collar mounted on the rocking bar, and hence preventing any rengagcment or relocking of these devices which would interfere with the further progress of the carriage. When the pendent projection has passed by the lug on the rocker-bar in any case and the carriage isreturned, the right-hand side of the pendent projection strikes against the left-hand side of the lug, and the pendent projection is tilted in a reverse direction to enable it to pass by said lug, whereupon the Weight attached to said projection restores it to its normal position. The pendent projection acting upon an inclined ledge 53 is adapted to rock the bar 1 and to cause the alarm to be sounded several spaces before the locking or intercepting of the escapement, the said bar having on its under side a bell-hammer arm 54, adapted to strike a bell 55 upon rco IIO
the release of said bar when the pendent projection escapes from the said ledge.
The feed-rack 7 engages with a pinion 56 on the inner end of a shaft arranged to rotate in a fixed housing 57, and at near the rear end of said shaft is mounted an escapement-wheel 58, with which the dogs 48 and 50 cooperate in the usual manner. The carriage is connected to the spring-drum through the usual strap or band 59.
Vhat I claim as new, and desire to secure by Letters Patent, is-
l. In a type-writing machine and in a linelocking mechanism, the combination of a carriage, a bar adapted to slide endwise, an arm or projection fixedly attached to the said bar, an escapement-rocker vibrating in a direction at right angles to said bar and adapted to be arrested by the said arm or projection when the said bar is slid endwise.

In a type-writing machine and in alinelockin g mechanism, the combination of a carriage, a bar adapted to be slid endwise thereby, an L-shaped arm iixedly attached thereto, and a dog-holder adapted to be thwarted in action by the interposition of the free end of the said L-shaped arm when the bar is slid endwise.
t. In a type-writing machine and in a linelocking mechanism, the combination of a carriage having a contact device, a rocking and lon gitudinally-movable bar having` also a contact device and also an attached locking-arm, a vibratory dog-holder having a projection adapted to be intercepted by said arm when the bar is slid endwise by the engagement of the said contact devices, and a release-key for rocking said bar and throwing the said arm up out of the path of vibration of the projection on the dog-holder.
5. In a type-writing machine and in a linelocking mechanism, the combination of a carriage having a contact device, arocking and longitudinally-movable bar having a contact device, a locking-arm fixed to said bar, a dogholder having a projection adapted to be i11- tercepted by said arm, a release-key for rocking said bar and throwing the arm up out of the path of vibration of the projection on the dog-holder, a spring for sliding the bar back to its normal endwise position and a spring for rocking the bar back to its normal horizontal position.
6. In a type-writing machine and in a linelocking mechanism, the combination ot' a carriage, an endWise-movable bar, a locking-bar secured thereto and projecting parallel therewith, and an escapement mechanism including a dog which is formed or provided with an integral upwardly-extending arm or projection to engage said locking-arm when the bar is slid endwise.
