UNITED STATES PATENT OFFICE.
SAMUEL J. SEIFRIED, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE MUNSON TYPE WRITER COMPANY, OF SAME PLACE.
SPECIFICATION forming part of Letters Patent No. 474,350, dated May 3, 1892 Application filed August 14, 1891- Serial No. 402,684- (No model.)
To all whom it may concern.-
Be it known that 1, SAMUEL J. SE1EEIED,a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in 'llype-WVriting Machines, of which the following is a specification.
My invention relates to improvements in type-writers wherein a rotatable sliding typesleeve is employed, and more particularly to improvements upon the type-writer heretofore patented to me in Letters Patent No. 411,066, of September 17, 1889, and No. 446,394, of February 10, 1891.
My improved type-writer has the same general principle and mode of operation as the machine heretofore patented to me in the Letters Patent above named.
The improvements which I have made are designed to simplify the construction of the machine, to render it more durable, its operation more efficient and certain, and to enable it to be more conveniently operated.
In my former machine the paper was wound around a paper holder or cylinder to keep the same out of the way of the hammer and the mechanism for communicating motion to the hammer.
In my present invention the hammer and part of the mechanism for communicating motion thereto are mounted upon a goose'neck frame orsupport, so that I can pass the sheet of paper around the hammer or between the hammer and the machine proper, thus enabling me to dispense with the paper-storage cylinder or roller, and thus materially diminish the cost of the machine, as well as greatly increasing the convenience of its operation in putting the paper in or out and adjusting the position of the same.
Another feature of my present improve ment consists in mounting the goose-neck hammersupporting frame to telescope or slide upon the main frame of the machine, so that the goose-neck will shut within the latter when the machine is not in use, and thus cause the machine to be as compact as though the goose-neck support for the hammer were not employed.
Another feature consists in the means for connecting and disconnecting the hammer operating mechanism which is mounted on the goose-neck frame with that which is mounted upon the main frame by the simple act of sliding the goose-neck in or out, so that no inconvenience may arise from the sliding or telescopic connection of the goose-neck with the main frame.
In my presentimprovement, as will be hereinafter more particularly explained, I have also materially simplified the mechanism for communicating the necessary rotary and sliding movements to the type-sleeve from the key-levers, also the mechanism for supporting and operating the ink-ribbon, and also the general construction of the paper-carriage.
My invent-ion also consists in the novel devices and novel combinations of parts and devices herein shown and described, and more particularly pointed out in the claims.
In the accompanying drawings, which form a part of this specification, and in which similar letters of reference indicate like parts throughout all the figures, Figure 1 is a plan view of a machine embodying my invention. Fig. 2 is a side elevation. Fig.3 is a vertical section taken on line 3 3 of Fig. 1. Fig. 4 is a vertical section taken on line t 4 of Fig. 1. Fig. 5 is a detail plan view of the key-levers and their connections. Fig.6 is a detail side elevation of the key-levers and mechanism for rotating the type-sleeve to change from one case to another. Figs. 7 and 8 are similar views of the same in different positions. Fig. 9 is a detail elevation of the mechanism for com municating the necessary rotary movement to the typesleeve. Fig. 10 is a detail perspective view of a part hereinafter to be described. Fig. 11 is a detail perspective view of the goose-neck frame orsupport upon which the hammer is mounted. Fig. 12 is a detail cross-section of the carriage. Fig.13 is a detail elevation of the mechanism for operating the paper-feed roller. Fig. 14 is a detail section of the escapement mechanism. Fig. 15 is a detail face view of the escapement-wheel. Fig. 16 is a section on line 16 16 of Fig. 7. Fig. 17 is a detail view of the latch for locking the cap-key lever and figure-key lever in place.
In the drawings, A'represents the frame of the machine. The frame A is furnished with IOU rubber feet or cushions A and with vertical side pieces or wings A upon which the main shafts of the type-writer are pivoted or journaled. The frame also has front and rear combs or slotted plates A and A to serve as guides for the key-levers.
B 13 represent the keys, preferably thirty in number, arranged in three transverse rows.
3 B B are the key-levers for the three rows of keys, pivoted to shafts 1) F12 respectively, and which extend across the frame.
0 is the rotary slidingtypesleeve, furnished with an annular groove 0 near its middle and a spline or projection c, which engages the longitudinal groove 0 in the rotary shaft C, upon which the type-sleeve is mounted. The rotary type-sleeve shaft Chas pivot-bearings c c on the frame of the machine,the pivot 0 being fixed in place by a set-screw c The type-sleeve O isalso provided with a series of registering notches c at each end, which fit the stop-pins D, with which they engage. The outer portions of these registering notches c are made inclined or cam-shaped at 0 so that the registering notch a will readily engage the stop-pin and the latter serve to cause the type-sleeve to accurately register both longitudinally and radially with the line of printing and properly space the letters therein. The type-sleeve 0 preferably has nine faces or rows of characters, with ten characters in each row or face,-five being on each side of the annular groove 0. The sliding or reciprocating movement of the type-sleeve C on its shaft 0 serves to bring the different characters in each row longitudinally into position in front of the impression-hammer, and the radial movement of the typesleeve by the rotation of its shaft C serves to bring each of the characters radially into position in front of the impression-hammer. The key-levers B of the first row of keys operate simply to slide the type-sleeve without rotating it, while the key-levers, B of the second row of keys operate not only to shde the type-sleeve, but also to rotate it one-ninth of a revolution, and the key-levers 13 of the third row of keys operate to slide the type-sleeve and to rotate it one-ninth of a revolution in the opposite direction. On the type-sleeve there are three different cases of type or characters, three rows or faces of the type-sleeve constituting one case of characters. To bring the second and third cases of characters on the typesleeve into the field of operation, two keys and key-levers are employed, one to rotate the type-sleeve one-third of a revolution, the other two-thirds of a revolution.
0 is the key and O the key-lever for the cap-case of characters, and P and P the key and key-lever for the figure-case of characters.
As the same sliding or longitudinal movement of the type-sleeve serves to move it into proper position longitudinally for the characters of each of the three faces or rows of characters, the keys and key-levers are arranged in sets of three, one key of each set being found in each of the three rows of keys, and for the same reason the registering or stop pins D are ten in number,arranged five on each side of the machine or at each end of the typesleeve. The two extreme stop-pins D may be fixed to the stationary frame-work of the machine; but the remaining eightf0ur on each sideare necessarily movable, so that they may be moved into and out of position for engaging the registering notches at the ends of the type-sleeve. The necessary one-ninth rotary movement of the type-sleeve is eommunicated thereto from the key-levers B of the second row of keys by means of a bar F, extending across all the key-levers B B B the keylevers B and B being, however, notched or otherwise so constructed that they will not engage or operate the cross-bar F, and the necessary one-ninth revolution of the type-sleeve C in the opposite direction is communicated thereto from the key-levers B of the third roW of keys by a similar bar F, extending across the same, the key-levers B and B being of course notched, so that they will not operate the bar F. The necessary sliding or longitudinal movement is communicated to the type-sleeve G from each of the ten sets of three contiguous key-1evers B B B by a series of rock-shafts G, ten in number, each having an arm g, furnished with a foot g, which spans the three contiguous keys B B B of each set. Five of these rock-shafts G are on each side of the machine, those on one side operatingtomove the typesleeve from its middle or normal position in one direction and those on the other side in the opposite direction.
It will be observed that the parts which I have thus far enumerated have substantially the same general construction and mode of operation as the corresponding parts of my former patents above mentioned.
The mechanism forcomm unicating the necessary rotary movement to the typesleeve C or its shaft C consists of the intermeshing gears (J C and swinging segment gear or rack (J mounted upon the pivot-bearing pin 0 of the shaft 0. The intermediate gear (J is journaled upon a swinging arm or lever C and the gear C is connected directly to the type-sleeve shaft 0. The segment or rack ,0 is operated by the case-key levers O and P through the connecting-link P having a pin at its lower end, which engages the levers O P. The cap-lever 0 serves to turn the segment 0 sufficiently to cause the typesleeve to rotate one-third of a revolution and the figure-lever P sufficiently to cause' the type-sleeve to rotate two-thirds of a revolution. The key-levers B of the second row of keys communicate the necessary one-ninth rotary movement to the type-sleeve through the cross-bar F, connecting-link f f, leverarms h h, and rock-shaft H, one of the arms h of the rock-shaft having a cam h, which engages a pin 713 on the bent lever K, which is connected by a link 70 with the lever or arm on which the gear 0 is journaled. The necessary one-ninth rotary movement of the type-sleeve in the opposite direction is communicated thereto from the third row of keys ]3 through the bar F, links f, rock-shaft H, having arms 7L2, one of said arms 72/ having a cam h which engages the pin 713 on the opposite side thereof from the lever-arm h, thus moving the arm 0 in the opposite direction. As shown in Fig. 9, the lever h is represented as being raised or partially raised by its link f, and thus in the act of causing its cam h to actuate the bent lever K. It will be understood that the lever h returns to its normal position when the other lever 72/ and its cam 71,3 are operating the bent lever K. The segment gear or rack C is preferably constructed with a hub C upon which the gear C and lever-arm C are journaled. The connection between the gear 0 and the type-sleeve shaft 0 preferably consists of an arm 0 on the shaft C, which fits in a slotted disk 0, se-. cured to the gear C 0 is a stop, which engages a stop-pin O on the swinging arm C to. approximately limit the throw of said arm in either direction to insure the proper engagement of the registering notches c on the type-sleeve with the stoppins D.
The necessary longitudinal movement is communicated to the type-sleeve C from each set of three keys, as before stated, through the rock-shaft G, having arm g, furnished with foot g. Each of these ten rock-shafts G is also furnished with an arm 9 which engages the horizontal cam-shaped lever J, the end of the leverJbeing curved or cam-shaped at 7" and engaging a pin it on the upright lever N, the upper end of which is furnished with a pin it, which engages the annular groove 0 in the type-sleeve. This upright lever N is made hook-shaped or curved, substantially as indicatedin the drawings, so that it will not interfere with the lower web of the ink-ribbon. The series of arms 9 on the rock shafts G move the type-sleeve longitudinally different distances, according to their distance from the pivotj of thelever J. The stop-pins D are connected to and operated by the arms 9 of the rock-shaft G.
M is the rock-shaft to which is secured the hammer-operating lever M; This hammeroperating lever M has feet or wings m m, which project over the arms 9 on the rockshaft G, so that the lever M will receive motion therefrom. The lever M, with its wings 117., also serves as a returning-lever to return the stop-pins D and their operating-arms g to their normal position after each impulse. This is done by a spring 1v connected to a lever M on the rock-shaft M, and which engages an arm m, rigidly secured to the rockshaft. The hammer-operating lever M is also provided with a cross-bar or bridge m having inclined or cam-shaped faces m m terminating in a registering notch m which engages the pin 41 on the lever N, which slides the type-sleeve, and thus serves to return the typesleeve longitudinally to position after each impulse. The rock-shaft M is further provided with a returning arm or lever M havinga double-inclined or earn-shaped notch m that engages the operating-pin 7c of the bent lever K, and thus serves to return it and the type-sleeve operated therefrom to position af ter each impulse.
The hammer-operating arm or lever M is furnished at its extreme end with a pin or projection m, which engages the hook-shaped or slotted arm 1", through which motion is communicated to the hammer R. The pin m has a pointed or conical end to insure the ready engagement of the same with the slotted arm r.
R is the goose-neck frame orsupport upon whichthehammerRismounted. Thisgooseneck frame slides or reciprocates on suitable guides a on the frame of the machine. The hammer R is secured to a rock-shaft R which is journaled in suitable bearings R on the upper limb of the goose-neck R, and motion is communicated to this rock-shaft from the slotted arm 7' through the rock-shaft R arm R link It, and arm R The slot 1'" of the hammeroperating arm 1' is widened at its outer portion 4*, so that the hammer, when an impulse is imparted to it from the pin m in the lever M engaging the slotted arm 4", will be free to rebound after striking the type-sleevethat is to say, the pin m on the lever M imparts at the first portion of its stroke a forward or striking impulse to the hammer R, the momentum of the hammer after thus receiving the impulse carrying it forward untilitimpinges against the type-sleeve. When the hammer impinges against the typesleeve, it is free to rebound, because at this time the pin m on the lever M is not in engagement with the edge of the widened slot 7" in the operating-arm 0". By this arrangement the hammer simply delivers a blow while freely suspended from its pivot and free to rebound. The hammer-head r is detachably secured to the hammer R by means of a set-screw r so that it may be conveniently and quickly removed and replaced by another removable hammer-head when desired for different kinds of work. For most uses ahard- IIO rubber hammer-head should be employed;
but for making a great number of manifold copies a harder or metallic hammer-head is preferably used. The hammerhead r is made star-shaped, so that it has a numberpreferably five-of operatingfaces r By thus making the hammer-head star-shaped with a number of operating-faces its durability is greatly increased. The central hole through the hammer-head, by which it is secured in place on the hammer bythe set-screw r serves, owing to the star shape of the hammer-head, to fix it properly in place for all its faces. By simply slipping the goose-neck R out on its guides a the slotted operating-arm r is brought into engagement with the conicalv on one spool and then on the other.
pointed pin m 'on the hammer-operating lever M. A set-screw R serves to fix the goose-neck ham mer-snpporting frame in place in its extended position. lVhen the machine is not in use or is being carried about, the goose-neck frame R is simply telescoped or slipped back on its guides within the main frame A, so that the machine as a whole has then no additional width.
By employing a goose-neck frame or support for the hammer and communicatingmotion thereto around the goose-neck I am enabled to'pass the paper between the upper and lower limbs of the goose-neck frame, and thus around the hammer or between the hammer and the machine proper, thus enabling me to dispense with the paper-storage cylinder or holder around which in my previous machine the paper was wrapped or wound.
Q and Q are the inking-ribbon spools. The shafts Q Q are journaled on a portion A of the main frame. The bridge portion A of the main frame is secured in place by screws. This bridge portion A of the frame has a depending standard A, upon which is journaled the ratchet q, through which motion is communicated to the spools fromthe pawl q' on the hammer-operating lever M. the depending arm or bracket A on the bridge portion A of the frame is a locking-pawl g which likewise engages the ratchet and serves to prevent any back motion thereof. This locking-pawl g has a weighted arm g to hold it in engagement with the ratchet-wheel q. Theshafts Q Q of the ribbon-spools are each furnished with a gear q or q, to one of which motion is communicated from the ratchetwheel by a gear q thereon, which meshes with an intermediate gear journaled on a swinging arm or lever g pivoted to the shaft of the ratchet-wheel. Secured to the gear q" is a smaller gear g that meshes with one or other of the .gears on the spool-shafts Q Q according as the lever g is shifted forward or backward. The lever g is furnished with a pin which engages a latch Q t/O hold the lever g in position. The ribbon (1 passes from one spool Q around the type-wheel O to the other spool Q. By shifting the lever g from one position to the other either spool may be driven, thus winding the ribbon e shafts Q Q of the ribbon-spools are made long enough so that the spools may be slipped into different positions longitudinally thereon, and thus bring different strips or portions of the ribbon in line with the impressionhammer. By this adjustment of the ribbonspools on their shafts, in connection with the winding or traveling movement of the ribbon, every portion of the ribbon may be utilized.
Back of the type-sleeve C, I provide a ribbon-guard Q having an opening Q therein for the face of the hammer to strike through. This ribbon-guard serves to keep the paper from coming in contact with the ribbon except at a point where the hammer-head strikes Pivoted to.
the same. The ribbon-guard Q is furnished with a pointer Q atits upper middle portion to indicate the point on the printed line where the hammer strikes. This is of service in making corrections and in adjusting the paper-carriage to position for work. The ribbon-guard Q is secured to a horizontal arm Q attached to a bracket Q on the main frame. The bracketQ is also furnished with a horizontal guide-arm Q to support the ribbon-guard at its lower edge and prevent the same coming in contact with the type-sleeve. This horizontal arm Q is also of service as a guide for the ribbon.
T is the paper-carriage. It slides on suitable guides a a on the frame of the machine, the guides or the carriage being furnished with friction-rolls t to cause the carriage to move easily. The carriage is furnished with a rack 'I', which engages the escapement mechanism. Pivoted to the carriage is a swinging frame T upon which the paper-feed roller T is journaled. The shaft T of the paper-feed roller is furnished with'a thu mb-piece or handwheel T at one end, by which the feed-roller may be turned by hand to adjust the paper in position when desired. At its opposite end the paper-feed roller is provided with a ratchet-wheel t and a gear-wheel 25 The gearwheel 25 meshes with a gear t secured to the ratchet-wheel 25 which is operated by a pawl t pivoted to the pawl-lever t. The pawl-lever 6 also has a pawl or tooth 15 which engages the locking-ratchet t on the paper-feedroll shaft. The pivotal or swinging arm T is provided with a graduated series of holes i in which fits a stop-pin t, that serves to limit the throw of pawl-lever t and thus the extent of feed of the paper. By adjusting the stop-pin t to different. positions the space between the lines may be regulated, as desired. The stop-pin t is mounted in a swinging arm or hearing t pivoted to the shaft 25 upon which the pawl-lever swings. The pivotal or swinging frame T that carries the paper-roller, is also provided with a curved shield or paper-guide T, upon which is j ournaled a small friction-roller T between which and the feed-roller the paper passes. This serves to insure a better and more convenient feed of the paper. The curved shield T is provided with a slot or opening for the friction-roll T to project through and with a curved lip T The curved shield T is provided with lips T", by which it is pivotally secured to the swinging frame T by pivots or screws T and adjusting-screws T connected by springs T with the shield T near its upper edge, serve to adjust or regulate the pressure of the shield and its frictionroll T against the paper-feed roll T For convenience in inserting the paper and also to keep the paper from the mechanism below, the paper-carriage T is furnished with a bot tom plate or guard T The paper-carriage is actuated in the usual manner by a main spring in the drum if? IIO through the connectingcord The papercarriage T is provided with an erasing-plate T to form a smooth and firm support for the paper, and thus enable erasures and correct1ons to be made without removing the paper from the machine. The pivotal or swinging frame T is likewise provided with a. bar T having a handle T at its end. This bar T swlngs past the erasing-plate, and thus permlts the paper to lie down against the plate. This bar T also serves as a guard for the paper to prevent it lapping backward over the hammer.
The escapement mechanism is substantiallythe same as in my previously-patented machine, and consists, briefly, of a shaft S, carrying a gear T, which meshes with the rack T on the paper-carriage T. The escapementshaft S is furnished with a sleeve S and a ratchet-wheel s and a clutch 5 The shaft S is also furnished with a sliding clutch .9 held in place by a spring .9 which engages the clutch The shaft S is also furnished with a sleeve 3 and a pin or crown wheel .9, having a slot .9 through which a pin 5 on the ratchet-wheel s before mentioned projects. A spring 3 connects the pin 8 to the pin .9 on the back of the ratchet'wheel s. The sliding clutch s" is actuated by a bent or thumb lever,S which is held in place by a spring S The pin or crown wheel 3 is engaged by the pawl-lever M on the rock-shaft M. The pawllever M is operated from the keys through the rock-shaft M, lever M, and rock-shaft G in the manner hereinbefore explained. The pawl-lever M is operated directly from the spacing-key V and lever V by the connectin g-link V Pivoted to the main frame at P is a looking latch or pawl P which serves when pushed inone direction to engage and hold the cap-key lever O in its depressed or operating position and when pushed in the opposite direction to hold the figure-key and key-lever P P in their depressed or operating position.
Y is the bell, which is operated in theusual manner when the carriageT reaches thelimit of its movement.
0 is the stop for the lever O, and l? the stop for the lever P.
P is the spring for returning the levers O and P'to position.
- The lever M is provided with a pin m which spans the lever-arms h W, and thus serves to return said lever-arms to place.
