TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 545,458, dated September 3, 1895.

Application filed March 16,1894. Serial No. 503,827. (No mod l.)

partly to an improved construction for the feed-pawl and its operative lever, partly to the construction of the platen, and partly to other details of construction hereinafter set forth.

My presentimprovements differ from others for effecting the same object 'in various respects, as hereinafter pointed out and claimed. In the annexed drawings, Figure l is a side elevation of a type-writer mounted upon a folding stand. Fig. 2 is an elevation, and Fig. 3 is a plan, of the same. One of the stand-legs is broken away in Fig. 2. Fig. 4 is an end view of the carriage. Fig. 5 is a plan of the same, broken across the middle for want of space upon-the drawing. Fig. 6 is a plan, Fig. 7 is a side view, and Fig. 8 is a rear view, of the ribbon-feeding mechanism. Fig. 9 is a plan, and Fig. 10 a side view, of the detachable foot-pieces for the type mechanism, with a portion of the bed for the same. Fig. 11 shows the-same parts in a different position. Fig. 3 is twice the scale of Figs. 1 and 2, and the remaining figures are drawn full size or twice as large as Fig. 3.

The frame of the type mechanism consists of a bed-ring A and upper ring A, connected by posts B, as in my Patent No. 477,404, and the bed is provided with foot-pieces E, which rest removably upon the stand formed of jointed legs I I.

The machine is illustrated with only the frame of the type mechanism and the carriage for moving the paper, as the improvements relate only to such parts, and the other parts are already well known and shown and described in the said patent. The jointed legs are united at the top by bars J, having canvas J stretched between the same.

The bed-ring A is provided with parallel studs D, projected from opposite sides, and the foot-pieces E are provided with rods E, corresponding to such studs, and with movable sleeves F, forming a socket-couplin g for the same.

The'jointed legs I are projected above the bars J which support the foot-pieces, to form stops adjacent to the foot-pieces and thereby preventany end movement of the type-writing machine, under the pull of the treadle connection, in reversing the carriage. Each of the foot-pieces E E is made in one piece, the bar E extending across both the bars J, with its ends E bent upwardly and then laterally to fit the'sleeves F. The ends of the legs I, which form the stops, are lettered I in Figs. 3 and 1.

The paper-holding carriage is formed at the edges of sheet-metal channel-bars 0, connected at the ends by tie-bars O, the channelbars being fitted to move longitudinally upon rolls G, which are pivoted upon the bed A. Such channel-bars are integral and form a very light construction, while they are very stifi, owing" to their form, and .are much cheaper than the solid bars provided with loose gibs, as heretofore, and as shown in my prior Patent No. 477,404, dated June 21, 1892.

The bed A in this class of type-writer car ries the fulcra of the type-bars H, one of which is shown in Fig. 2, which, when pressed by the button I1, strikes downward at the center of the bed-ring A, indicated by the letter a in Fig. 3.

The carriage is provided with a rectangular bar-platen K K K which is journaled in the carriage-bars C and extended across the center of the bed-ring A,t0 receive the impact of all the types. The two opposite sides K K are coated, respectively, with hard and soft india-rubber and two edges K of the bar are exposed. The bar is made of greater width than thickness, so that the faces K, K, and K are equidistant from the center of rotation. This feature of the construction is shown in Fig. 4, where the bar is shown of oblong crosssection, reduced to square form at the end to furnish four similar seats is to engage a spring is, which operates to hold the platen adj ustably with any of its four faces upward toreceive the impact of the types. The naked metallic surface is used to support the paper when it is desired to manifold heavily and the hard and soft rubber faces K and K are used in manifolding to a lesser degree. The hard rubber is used where the character of the impressions and'quality of the paper require such a support. The platen is turned by grasping it with the fingers, the spring 7r yielding during the rotation of the platen.

The paper-feedin g roll L is shown adjacent to the platen and provided at the outer end with head L to turn the same.

A ratchet-wheel Z is provided near the bar 0', and a hand-lever M is pivoted upon the bar and provided with a pawl which is held normally out of engagement with the ratchetwheel by a spring m depressing the lower end. The ratchet-wheel is provided with six teeth, and the pawl is so constructed as to turn the wheel one-third of a rotation to produce a coarse-line feed with a feed-roll of very small diameter, as is shown in the drawings, and also, when desired, to reduce such line-feed one-half. To thus rotate the ratchet-wheel the pawl is formed with two teeth Z and Z and with a toe m, which is pressed against a pin upon the hand-lever by a spring m" to hold the pawl-teeth into engagement with the wheel Z. The hand-lever moves the pawl sufficiently to engage such teeth successively with the ratchet-wheel and thus turn it one hundred and twenty degrees.

The ratchet-wheel is prevented from overfeeding by a tooth n, fixed upon the hand- 1 auxiliary lever is shown in an arm 11/, pivoted lever and adapted to enter the space between the ratchet-teeth at the close of each feed, as shown in Fig. 4. The hand-lever is formed of flat sheet metal with a slot 0 cutthrough the same to admit a feed-regulator, consisting in a rotary stud 19, having a pin '0' projected from one side, and provided with a handle p. A stop-pin o is provided at the side of the stud and when the handle is turned upward, as shown in Fig.4, the pin intercepts the upper side of the slot 0 and reduces the movement of the hand-lever just one-half. When the handle is turned to the left, with the pin 0' against the stop, the hand-lever is moved by'spring on to the position indicated by the dotted lines M, and the pawl is then held from contact with the ratchet-teeth, as indicated by the dotted lines Z in Fig. 4, thus permitting the operator to turn the feed-roll backward, if desired, by means of the head L.

InFig. 3 the headA is shown provided with a spring-drum N and cord N to shift the carriage step by step automatically in the usual manner when the type are depressed.

The treadle is shown in Figs. 1 to'3, and its connections to the carriage are adapted to simultaneously operate the pawl and thus actuate the line-feed automatically each time the carriage is reversed. The treadle P is shown pivoted to a guard-block Q, secured to one of the stand-legs,'and its opposite end connected by cord S with the short arm R of a bell-crank, pivoted upon a bar S between the legs. The bell-crank is shownwith a long arm R extended to the top of the stand, where it may be connected with the carriage by a link orby a flexible cord 8, as shown in Figs. 1 and 3.

To actuate the line-feed when the carriage is reversed an auxiliary lever T is shown pivoted upon the bar 0 in Figs. 4 and 5 and its outer end extended into line with the cord 3, a spring 15 serving to hold such end elevated.

The carriage is shown with an extensionpiece U projected outward and provided with a pulley u beneath the end of the lever, the cord .9 hanging behind the pulley in Fig. 4, with an eye 8' upon its lower end. Such eye is adapted to slip over the end of the bellcrank arm B. when it is desired to use the treadle, the spring in the drum N being made of sufficient strength to shift the carriage and simultaneously raise the treadle. The auxiliary lever T is adapted by a lateral stud t to engage the under end of the pawl, and a pull upon the cord 8 thus operates, first, by depress- 1 ing the outer end of the lever T, to press the pawl upward and actuate the ratchet-wheel Z, the stop at then preventing any further move- .ment of the lever T, and a continued pull upon the cord then shifts the carriage in the desired manner. A depression of the treadle A stop for checking the movement of the upon the extension U, and provided with a handle 11, to shift the same beneath the lever T, as shown in Fig.4. are shown in a reverse position in Fig. 5. 'VVhen in such position, the stop holds the lever i'from movement and the treadle effects the The handle 162 and stop reversal of the carriage only. To limit the movement of the carriage when actuated by the treadle, an abutment V is formed upon the bed A, Fig. 3, and dogs 0 (shown in Figs. 3 and 5) are fitted to a square bar to, attached to the carriage under such abutment. The

dogs are provided with eccentric-cams 1:,

adapted to pinch the bar and clamp the dog firmly in position. The cams have handles 11 the one at the right being turned to release the dog and the one at the left with its cam pinched upon the bar.

The paper Y is indicated by dotted lines passing over the feed-roll L and platen K in Fig. 5, and in practice would be pressed upon the top of the feed-roll by suitable presserrolls, as shown in my aforesaid Patent No. 477,404.

The foot-pieces E are made of the peculiar shape shown herein to extend across the top of the folding stand and rest upon both of the bars J, and are made detachable from the bed-ringA to facilitate the packing and transportation of the parts. The means for the application of the foot-pieces to the machine and'means for locking them thereon are constructed as follows: The sleeve F is formed with a notch 1) upon its outer end to assist in centering the rods upon the studs when first applying the feet thereto, as shown in Fig. 11.

Screw-pins c are fitted through slots in the sleeves to limit the movement, and a yoke of is fitted around the outer end of each sleeve to carry an eccentric-cam c. The cams are provided with handles fiwhich when turned down, as shown in Fig. 10, press the cam upon the stud D and thus lock the foot-piece to the stud. By turning the handle up, as shown in Fig. 11, the cam is withdrawn from the stud and the foot-piece may be withdrawn. The sleeves F carry brackets f, provided with rolls f adapted, like the rolls G, to fit the channel-bars O and guide the carriage when it is near the opposite ends of its stroke. By means of the eye 8 upon the cord 8 (shown in Fig. 4) the cord furnishes a detachable connection with the treadle, the cord also serving as a flexible connection to draw the lever T downward before shifting the carriage. Where the treadle is intended to reverse the carriage only, the arm B may be connected directly to the carriage by a detachable link or any other suitable connection. By making such connection detachable the carriage can be shifted by hand to write titles, headings, andother kinds of work which are usually performed without using a line-stop. The dogs 12 are intended to form stops at the opposite ends of the line and thus regulate the movement of the carriage when shifted by the treadle in writing lines of uniform length. By securing the dogs 1) and the sleeves F by cams instead of setscrews, as shown in Figs. 3 and 4 herein, such parts may be released and fastened by a single rapid motion of the fingers. The guardblock Q prevents the operator from pressing the treadle accidentally when it is not required for use in reversing the carriage, and it is extended along the treadle about onehalf its length for such purpose, as shown in Fig. 1, which exhibits the rear side of the machine. The operator would sit upon the opposite side of the machine and the guardblock would be projected upward beyond the path or stroke of the treadle in its extreme upward movement. As the guard-block would thus cover a portion of the treadle, it is adapted to support the operators foot when not using the treadle.

The folding stand shown herein is, with the constructive features of the type-writer, especially adapted to render the whole apparatus portable, and I have therefore claimed the same as constituting a cheap and effective means of adjusting the machine detachably to a stand provided with a treadle.

In Figs. 6 to 8, inclusive, is shown a means for reversing the ribbon-feed, the ribbonspools g g being mounted upon a bearingA attached to the rear side of .the ring A, as shown in my Patent N 0. 477,404. The spools are provided,respectively,with ratchet-wheels h h, and are mounted to turn with such wheels upon a stud g fixed in the bearing A Levers h? are pivoted upon the bearing A and are both actuated by a toe h attached to a rod B, which reciprocates at each movement 'of the letter-spacing mechanism. Pawls 21 z" oted upon the bearing A between the pawls and is adapted to throw the opposite points ofthe wedge, respectively, behind the pawl 13 or i, and thus detach either of such pawls at pleasure from contact with its ratchet-wheel.- The lever or handlej' is shown in Fig.8 pushed to the left, and the pawl 2 thereby detached from the wheel 72.. The pawl 2' remains in contact with the wheel h, and thus actuates the spool g to wind up the ribbon, as required. By shifting the handlej to the reverse position the pawliwould be detached from the ratchetwheel and the pawl t" would become operative.. It will be noticed that the pawls operate automatically through the constant pressure exerted by the springs 4?. The double wedge 3' thus differs from any heretofore used in its particular arrangement upon the 5 bearing A and its adaptation to hold either pawl from performing its normal function. Stop-pins are shown upon the bearing just above the fulcrum of the lever 7' and the lever is shown in contact with the left-h and pin. Such stops prevent the lever from movinginto contact with the wheels h h when pushed by the operator. 7

I have already stated that the spring in the drum M is made of sufficient strength to not onlyshift the carriage, but to simultaneously raise the treadle P. The spring is enabled to raise the treadle (without materially strengthening the spring) by the vertical arrangement of the bell-crank arm R and the great proportion of its length'to the horizontal arm B. By such arrangement the spring is required to lift only a small proportion of the bell-cranks weight, and the bell-crank lever and treadle, being wholly unbalanced when detached from the carriage, retain voluntarily their lowest positions, which they would not do if provided with special means for counterbalancing their weight. When the treadle is connected with the carriage by the. cord 3, it follows the movement ofthe carriage, and as the tension of the spring N balances the treadle the carriage may be shifted by hand in the usual manner. When the cords is detached, the weight of the treadle draws the bell-crank arm R out of the way automatically, and the type-writer carriage may then beshifted by hand or the machine removed and the stand folded for transportation. The treadle P is attached by pivot to the guard Q,

which is secured to the legs I, the same as the bar S, upon which the bell-crank is mounted, and the relation of the treadle and the bellcrank is thus preserved at all times.
