LEENDERT PIETER LPOLHUIS, 0F AMSTERDAM, NETHERLANDS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO UNION TYPEWRITER COMPANY, OF JERSEY CITY, NEW JERSEY,

A CORPORATION OF NEW JERSEY.

TYPE-WRITING MACHINE.

To all whom it may concern:

Be it known that I, LEENDERT Pmrnn POLHUIS, citizen of the Netherlands, and resident of Amsterdam, in the Province of Noord, Holland, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relates to typewritin machines and more particularly to tabu ating mechanism.

The present invention is in the nature of an improvement on the constructions disclosed in the patents to Sivertsen and Nielsen No. 971,696 and to Oscar \Voodward No. 071,953 and is directed more especially to the resetting mechanism and to the mannor of controlling the same. I

The main object of my invention, generally stated, is, to provide improved and efficient means which are readily accessible to the operator for quickly clearing or resetting a series of previously set tabhlator stops when new, or differently arranged, stops are to be employed.

Another object of my invention is to provide, in a construction of the character specified, means whereby an actuation of a key is effective to render the resetting mechanism operative and to simultaneously release the carriage.

A still further object of my invention is to provide means whereby a release of the carriage may be effected by an operation of the stop resetting means without bringing the speed controlling means for the carriage into operation so that the full force of the power employed to move the carriage may be made available to reset the stops to inoperative posltlon.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, combinations of devices and arrangements of parts to be set forth in the following description and particularly pointed out in the appended claims.

In the accompanying drawings wherein Specification of Letters Patent.

Fig. 3 is a skeletonized side elevation with parts in section, and showing a portion of the tabulating mechanism. Fig. 4 is a fragmentary plan view, on a larger scale than the preceding figures, of some of the parts represented in Fig. 1. Fig. 5 is a fragmentary detail front elevation showing the buffer, the auxiliary release, the connections between the two and some of the associated parts. mentary detail side elevation with parts in section of the resetting mechanism, auxiliary release and some of the associated parts.

I have illustrated only so much of the typewriting machine as may be necessary to arrive at an understanding of my invention, and various parts of the structure are conventionally represented in order to simplify the showing.

I have shown my invention embodied, in the present instance, in a No. 11 Remington machine, in which the invention may be readily embodied without changing, or ma-' terially changing, any of the structural features of said machine as it now exists. It should be understood, however, that the invention may be embodied in various styles of typewriting machines and that various changes may lie-made in the structure to facilitate such embodiment.

The frame of the machine comprises a base 1, corner posts 2 and a topplate 3. Type bars 4 are mounted in the usual manner to strike upwardly and rearwardly against the front face of a platen 5 which is carried by a carriage (5. The carriage is mounted on anti-friction balls or rollers 7 for movement from side to side of the machine over the top plate. Upwardly projecting lugs 8 extend from the rear cross bar of the carriage, and have rearwardly extending arms 9 pivoted thereto at 10. These arms are connected at their rear ends to a feed rack 11, adapted to mesh with a feed pinion 12 which is operatively connected in the usual manner to the escapement mechalllSll'l. Upon reference to Fig. 4, 1t Wlll be seen that a leaf spring 13 is fixed at one end by screws 14 to the rear cross bar of the carriage and bears at its free end on one Fig. 6 1s a frag Referring now more particularly to Fig.

3 it will be seen that the tabulating mechanism comprises rearwardly extending bracket arms 17 ,which are secured to the rear cross bar of the carriage by screws 18 and support a column stop bar 19 at the rear ends thereof. This column stop bar is provided with teeth 20 on the upper and lower sides thereof, and plate-like, sheet metal, bifurcated column stops 21 are received in the interdental spaces between the teeth 20; adjacent spaces being situated a letter space distance apart. The column stops 21 are adapted to slide fore and aft of the machine on the column stop bar into and out of operative position; one of the column stops being shown in the operative position in Fig. 3, Upright denominational stop levers 22 are pivoted at 23 in a tabulator frame 24, which is secured in the usual manner to the frame of the machine. The upperends of these levers 22 extend forwardly where they constitute denominationalstops 25. The lower end of each denominational stop lever 22 is pivoted to the rear end'of a link 26. Each link 26 has its forward end pivoted to an angular lever 27, mounted on a pivot rod 28 whichis fixed to the base of the machine. The forwardly projecting arm ofeach angular lever 27 extends through an opening in'a key stem 29 guided in openings in

guide plates

30 and 31, and provided at'its upper end with a denominational key 32. A contractile spring 33 is connected at one end to the guide plate 31, and at its opposite end to the dependingarm of the angular lever 27. One of these springs 33 is connected to each angular lever 27 and is effective to restore the angular lever and the parts connected therewith to normal position. A universal release bar 34 extends in the rear of the depending arms on the angular levers 27 for cooperating therewith. This release bar is provided with upwardly ex'tendingarms 35 at the ends thereof, which arms are pivoted on the pivot rod 28. A rearwardly extending link 36 is pivoted at its forward end to one ofthe arms 35, and at its rear end to. a depending crank arm 37 on a rock shaft 38.

1 This same rock shaft is provided with a curved crank arm 39 connected to the lower end ofa .link40. The link 40 has its upper end connected to a rearwardly, projecting arm 41 of a carria ge releasing frame 42, pivoted at'43 to a supporting bracket 44, secured to the top plate of the machine.

The frame 42 has bearing openings for a shaft .45, provided at its forward end with a pinion 46 fixed thereto, and a beveled pinion 47 is fixed to the rear end of the shaft 45. A downward pull on the link 40 is effective to turn the releasing frame on its pivot 43, thereby elevating the pinion 46 to throw it into mesh with the feed rack 11 on the carriage, and to move the feed rack upwardly out of engagement with the feedpinion 12, thereby disengaging the carriage from the escapement mechanism. This same movement of the releasing frame is effective to move'the beveled gear 47 down into mesh with a beveled gear 48, connected to a shaft carrying stirrer arms which rotate within a housing 49 fixed to the top plate of the machine. This housing contalns shot, or some such substance, to retard the rotative movement of the shaft carrying the beveled gear 48; the carriage speed controlling means as a whole being similar to that employed in the No. 11 Remington machine. It will be understood that when the carriage is released I in the manner described, the power applied to the carriage will be transmitted from the feed rack 11 to the pinion 46, shaft 45,. beveled gears 47 and 48 and speed controlling device, to retard the'movement of the carriage and so reduce theshock when the carriage is arrested by the cooperation of a projected denominational stop with a column stop.

From the foregoing description it will be understood that the depression of a denominational key is effective to move the companion denominational stop 25 to operative position, where, it extends in. the path of the operative column stops 21. This same movement of the denominational key is efiective to transmit movement to the carriage releasing frame through the releasing bar 34,

link 36, crank arm 37, rock shaft 38, crank.

arm 39 and link 40, to effect a release of the carriage and to throw the carriage retarding, or speed controlling, means into opera- .tion. When pressure on the key is released the spring 33 is effective to restore the key and the parts connected therewith to normal posit-ion. In order to restore the carriage releasing frame 42 and the parts which control it to normal position, I have provided a depending arm 50 on the rock shaft 38 which arm is connected to one end of a contractile spring 51 which is connected at its opposite end to a depending pin 52 secured to the base of the machine.

In order to move the column stops to operative position I have provided a projecting device which is in the nature of a crank arm 53, secured to one end of a rock shaft 54 mounted to turn in bearing openings in the two arms of a bracket 55, the bracket being secured to the top plate of the machine by-screws 56. From an inspection of Fig. 4 it will be seen that the crank arm or projecting device 53, has an off-set engaging portion 57 of a width or thickness which is such that it will cooperate with but one of the column stops at a time. A collar 58 is fixed'to the rock shaft 54 and one end of a coiled spring 59 is secured to the collar; the opposite end of the spring being connected to the right-hand upwardly projecting arm of the bracket 55. This springexerts its force to return the device 53, the rock shaft. 54 and the parts which control these members to operative position. The left-hand end of the rock shaft '54 has fixed thereto av rearwardly projecting crank arm 60. To this arm is pivotally connected the upper end of a downwardly extending link 61, which extends through an opening (32 in the top plate of the machine. This link is connected at its lower end to a key lever 63, fulcrumed on a fulcrum bar 64 and provided at its forward end with a key (35 arranged in the'rear of printing keys (36. It will be understood that a depression of the key 65 is effective to rock the shaft 5-1, thereby moving the device 53 rearwardly to move the column stop 21, which is in alinement with the engaging portion 57, rearwardly on the column stop bar to operative position, where it is adapted to remain indefinitely or until such time as it is moved back to inoperative position. It will be understood that during the travel of the carriage, the column stops are brought successively into coiip'erative, relation with the engaging portion 57 of the device by which the column stops are moved to operative position, and that therefore the position of the carriage in its line of travel determines which column stop may be moved to operative position.

I have provided means wherebythe operative column stops may be cleared, or moved forwardly to-inoperative position on the column stop bar, when the character of the work is such as to require the use of a new .or different set of column stops. This means I refer to as a resetting means or de-' vice by which the column stops may be reset to their inoperative position. Such means comprises a camor wiper 67, provided with a stem 68 mounted in a bearing opening in 'the tabulator frame 24. and having oppositely inclined contact faces 69. These faces are adapted to coiiperate with those column stops which are in the operative position,

when .the resetting device is moved forwardly from the normal position shown in Fig. 4 to the projected position shown in Fig. 6. It will be seen that the. resetting device is movable foreiand aft of the machine,-or in the same general direction as the movement of the column stops in their movements into and out of operative position. A vertically-disposed opening 70 (Figs. 2

and 5) is provided in the tabulator frame 24 to receive a verticall movable device 71 by which the resetting evice 6768 is controlled. The member '71 is provided with a cam 72 in the nature of an inclined projection extending from one side .thereof. The cam 72 is normally received in a correspondingly shaped inclined cam slot 73 formed in the stem 68. A downward vertical m0vement therefore of the member 71 is effective to cam the member 67-'-68 forwardly to the operative position as shown in Fig. 6, whereas an upward movement. of the member 71is effective to cam the resetting device 67-438 rearwardly to the normal or inoperative position shown in Fig. 4. The device 71 is normally maintained in the elevated position by an extension spring 7-1 which surrounds the stem of the member 71 and rests at its lower end on a supporting hub 75 perforated for the free passage therethrough of the stem of the member 71. The upper end of'the spring bears against a cap or finger key 76 which is threaded onto the upper end of the stem of the member 71. The force of the spring 74 is therefore exerted to normally maintain themember 71, and the finger piece connected thereto. in theelevated position and to maintain the resetting device controlled thereby in the normal or lnoperative position. A downward movement of the member 71 to the position shown in Fig. (i is effective, as hereinbefore pointed out, to move the resetting device to operative position and near the limit of the downward movement of the member 71, the forward end or contact shoulder 77 of the cam 72 is brought into engagement with a corresponding vertical face or contact shoulder 78 on the member 68, so as to lock the resetting device against return movement' by pressure of the column stops exerted thereon. It will be seen therefore that the resetting device is automatically locked against return movement bythe action of the column stops thereon, while the latter are being moved to inoperative position. The resettingmechanism' thus far describedis the same as that disclosed in the patent to Oscar Voodward hereinbefore referred to, and further detail descriptionthereof isdeem d unnecessary. In .fact, so much of the typewriting machine, the tabulating mechanism, the release controlled thereby. the speed controller, the means for setting the stops, and the resetting means by which the column stops are cleared, which have thus far been described, are the same in construction as are ordinarilyemployed in the No. 11 Remington machine, although, as herembefore pointed. out, some of the parts are conventionally represented in the drawings for clearness of illustration.

in the presence instance I have provided means whereby the resetting device may be machine and at the keyboard, What I term a resetting key 7 9 arranged to the left of the denominational keys 32. This resetting key is provided with a key stem 80 received in guide openings in the

plates

30 and 31. The key stem 80 is connected to an angular lever 81 similar to the angular levers 27 hereinbefore described, and like such levers 27 is pivoted on the pivot rod 28. A contractile spring 82 is connected at one end to the depending arm of the angular lever 81 and at its opposite end to the guide plate 31. A rearwardly extending link 83 is connected at its forwvardend to the depending arm of the angular lever 81, and at its rear end to a depending crank arm 84. This crank arm is fixed to a sleeve or hollow rock shaft 85 which loosely surrounds the pivot rod 38. A curved crank arm 86, similar to the crank arln 39 hereinbefore referred to, is fixedly connected to the sleeve or hollow rock shaft 85 so that a movement of the arm 84 is effective to producea corresponding movement of the curved crank arm 86. An upwardly extending link 87 is connected at one end to the crank arm 86 and at its opposite end to a crank arm 88 which, as will be seen from an inspection of Fig. 1, constitutes the part of a frame, designated as a whole by the reference numeral 89, made up from sheet metal and shaped into substantially Y-form. The sides of the stem of the frame are connected by across bar, or rivet 90,by which two side arms of the frame are rigidly united. The frame is perforated to provide bearings by which it may be pivot ally and loosely mounted on the rock shaft 5-1. The forward end of the frame 89 is provided with a contact shoe 91 which extends beneath the feed rack 11 and is adapted to engage a toothed face of the feed rack to elevate the rack, thereby disengaging it from the feed pinion 12, to free the carriage from control of the escapement mechanism. It, will be understood that-this carriage releasing device is in the nature of an auxiliary releasing device operable independently of the carriage releasing frame 42 controlled by the tabulator, and that an actuation of this auxiliary releasing device or frame 89 is effective to release the carriage without bringing the speed controlling means 49 for the carriage into operation.

In short, the speed controlling means are only brought into operation Whenthe carriage is released through an actuation ofa tabulator key. The other arm 92, of the frame 89, is pivo'tally connected by a headed pin or shouldered screw 93, which projects laterally from the depending end of the member '71 which controls the resetting device as indicated in Fig. 6. This pin is received in an elongated slot 94 in the arm 92. It will be understood therefore that a downward movement of the link 87 is effective to turn the frame 89 on the rock shaft 54, thereby elevating the forward end of the frame, to disengage the rack from the feed pinionas shown in Fig. 6. At the same time the downward movement of the arm 92 is effective to pull the controlling device 71 down against the pressure of the spring 74. to the operative position, shown in Fig. 6. This movement of the controlling device 71 is effective to cam the resetting device forwardly to operative position and to automatically bring about a locking of the resetting device in the operative position by an engagement between the contact shoulders 77 and 78. An actuation of the auxiliary releasing device therefore throws the resetting device into operation and releases the carriage from control of the escapement 95 mechanism, and as the carriage moves under the power .of its spring drum the column stops which are in the operative posit-ion will be successively moved or cammed forward to inoperative position. At this time the full force of the carriage spring is effective to aid in reset-ting or restoring the column stops to normal or inoperative position.

The carriage being free from control of the speed controlling mechanism when the resetting device is moved to operative position, it is desirable to provide a buffer or shock absorbing means to prevent undue shock between the carriage and the line lock stop at the completion of the run of the carriage. I have therefore provided a buffer which is automatically thrown into operation when the resetting device is moved to operative position. Thus-from an in- 1 5 spection of Figs. 4, 5 and 6 it will be seen that the carriage releasing frame 89 is providedwith a forwardly projecting pin 95 which is received in a slot 96 in a lever 97 of the first order. This lever is pivoted on a. i

A bracket 104 is secured to the carriage by the screw 14. This bracket is provided with a cylindrical plunger casing 105 which receives a headed plunger or buffer 106. A.

coiled expansion spring 107 surrounds the stem of the plunger and bears at its righthand end against the perforated bottom of the cylinder 105 through which the stem of the plunger works; The opposite end of the spring bears against the head of the means whereby the force of the spring 107 may be regulated to a slight extent.

In the normal position of the parts the contact portion 103 of the buffer 100 is maintained below the path of travel of the plunger or buffer 106. When, however, the resetting device is moved to operative position the ivotal movement of the frame 89 is e ective to elevate the righthanden d of the lever 97, thereby moving the buffer 100 on its pivot to bring the contact face 103 thereon into the path of the plunger 106. The buffer 100 is therefore automatically rendered operative to co-act with the buffer 106 to arrest the carriage when the resetting device is moved to operative position and the carriage is freed under control of the escap'ement mechanism by the auxiliary releasing frame 89. The

buffers therefore become effective to absorb the shock and reduce the force of the impact when the carriage is arrested. From an inspection of Fig. 2 it will be understood that' the

buffers

100, 106 do not, in any event, become effective until the' carriage has moved to a position where it is beyondv thefield or range where the tabulating mechanism is effective to arrest the carriage. The buffers therefore will never be eifective to arrest the carriage when the tabulator is in operation, no matter at what point in the travel of the carriage it may be arrested by the tabulator mechanism.

From the foregoing description it will be understood that a depression of the key 79 is effective to move the resetting, device 67 forwardly to operative position and at the same time to release the carriage and interpose the buffer 100 into the path of the cooperating buffer 106 on the carriage' The carriage spring is then effective to move it in the direction of its feed under the full power of the carriage spring and those column stops which are in the operative position will be successively cammed forward to inoperative position on the column stop bar. When allof the stops have been cleared the carriage is finally arrested by the cooperation of the

buffers

100 and 106,

so as'to absorb the shock incidental to the arrest of the carriage. When pressure is released on the key 79 the s rings 82 and 74 are effective to restore t e parts controlled thereby to normal position, thereby w1thdrawing the resetting device and loweringthe rack into engagement with the feed pinion.

It should be understood that when the buffer 100 is moved to operative position the force of the impact on the contact face 103 thereof is effective to turn the buffer 100 slightly on its pivot 101, so .that the impact between the buffers tends to restore the resetting device and the parts connected therewlth to normal position and to move .the buffer 100 out of cooperative relation with its cooperative bufler 106.

Various changes may be made without departing from the spirit and scope of mv invent-ion.
