TYPE-WRITING MACHINE.

Application filed January 4, 1911.

To all whom it may concern Be it known that I, ARTHUR W. SMITH, citizen of he United States, and resident of the borough of Manhattan, city of New York, in the county of New York and State of New York, haveinvented certain new and useful Improvements in Type Writing Machines, of which the following is a speoi speed controlling mechanism is normally operatively connected with the carriage, though said mechamsm 1s ineffective to retard the carriage but may be rendered effective at will, as for instance when atabulating operationtakes place.

To the above and other ends which will be hereinafter described the invention consists in the features of construction, combinations of devices and arrangements of parts to be hereinafter set forth and particu larly pointed out in the appended claims.

.In the accompanying drawings wherein like reference characters indicate corresponding parts in the various views, Figure 1 is a fragmentary central vertical sectional view of one form of typewriting machine embodying my invention; only so much of said machine being shown as is necessary to illustrate myinvention in its embodimenttherein. tary detail perspective view showinga portion of the tabulating mechanism.

Serial No. 600,758.

such as is embodied in that machine, and similar to that disclosed in the patent of I Clio B. Yaw, No. 984,338, dated February 14, 1911. that the invention may be embodied in va- 'rious styles of typewriting'machines and fixed oppositely grooved rails 7 supported on upwardly extending lugs 8 fixed to the top plate of the machine. A rotative platen 9 is supported by the carriage; the platen and inann'erjof supporting it being conventionally represented in the present instance. Rear'wardly extending arms 10 are pivoted at 11 to upwardly extending lugs on the carriage 'andare fixed at their rear ends by screws 12 to a feed rack 13; The feed rack meshes with a pinion 14 fixedly mounted on the forward end of a shaft which turns -m a bearing 15 secured to the top' plate of the machine. The rear end of the shaft has an escapement wheel 16 connected thereto .for cooperation with the usual key controlled carriage feed mechanism, not shown. It will be understood that; when the feed rack 13 is moved upwardly out of engagement 'with its cooperative feed pinion, the carriage is freed from control 'of the escapement mechanism and is' free to be pro pelled from right .to left by the usualspring drum 17 connected to the carriage by a strap or band IStiXed' at one end to the drum and at its opposite end to'an arm 19 fixed to the carriage.

Rearwardly extending bracket arms 20 project from the carriage and support a column stop bar 21 formed with teeth 22 011 opposite sides thereof for the reception of bifurcated column stops 23 received .inthe interdental spaces between the, teeth on the column stop bar. Rearwardly projecting 27 and 28 on a stop head 29 fixed at-the up-- per end on a vertically disposed shaft 30 mounted to turn in hearings in the frame of It should be understood, however,

the machine. Thus the shaft passes through an "opening in the top plate and turns ,in and 'i'slsupported by a bearing member 31 (Fig. 5) having-a flange 32 which is'fixed to the top plate of the machine. A coiled spring 33 is contained within the bearing 31 and Surrounds the, shaft '30. .One end. of this spring is fixed to' ,the shaft by being received in a groove 34 thereimthe other end, .of the spring being received in -a slot 35 in I the bearing 311 In this manner one end of the spring is fixed to the bearing. member and-the other end is fixed to the shaft 30 and tends to rotate the shaft so as to normally ,maintain the portion 36 of the stop head, which is without stop projections, opposite the column stops, so that normally the car riage is free to travel and carry the column stops past the stop head 29-.

The lower end of the shaft 30 is provided with a pinion 37 which meshes with rack with an upwardly projecting pin 42 near the right-hand end thereof, which pin is reteeth 38 on a slide bar 39 mounted to move longitudinally in grooved bearing openings 40 of a bracket 41 secured to the jframeof the machine. The slide bar 39 is provided ceived in a slotor cut-out. 43 in a plate or slide 44. This plate is mounted in grooved bearings in'the bracket 41 to slide fore and aft 'of the machine and is provided with a cam face or edge 44 at the left-hand--end of the slot for coiiperation with the pin 42. It will be understood therefore that a rearward movement of the slide 44 from the normal position shown in Fig. '2 will cause the "slide 39 to be movedto the right through the'coiiperation of the cam 44 with the pin 42. This movement will be transmitted through the rack 38 and pinion'37 to effect a rotative movement; of the head 36, in orderto bring the first of the stops thereon (24) into the path of. the column stops to render the column stops cooperative therewith. A pawl 45 is pivoted to the bracket 41, as indicated at 46. A leaf spring 47 bears down at its free end on top of the pawl 45 and tends to depress the lower engaging tooth (not shown) thereon into engagement with the ratchet teeth (not shown) on top of the slide 39 to hold the slide against return movement after it starts its movement to the right. A downwardmovemerit of the pawl is afforded by a forward movement of theplate 44, and a rearward.

movement of the plate 44 is efl'ective to elevate the pawl 45 through the cooperation of the cam faces-48 and 49 on the plate 44 and pawl 45 respectively. The elevation of thepawl is effective to disengage it from the ratchet teeth of the'slide' 39 to enable said slide and the stop head 29 to return to normal position.

The extent to which the stop head 29 may be rotated by the various column stops determines the selection of the column and the extent of travel of the carriage. The extent of rotative movement of the column stop head is determined by a series of key."

actuated slides 50 arranged to slide fore and aft of the machine in grooved bearings in the bracket 41. These slides normally are maintained out of the path of longitudinal movement of the slide 39 and are 7 adapted to be projected across the -slot 40,

through which'the slide 39 moves, and into the path of'said slide in its movement from left to right. The effect" of a rearward movementof one of the slides 50 is tocarry it into the path of movement of the slide 39, and when thetravel of the carriage brings the column stops successively into coopera tion with the different stops 24, 25. etc.,' on

- the stop head 29 the shaft 30 will be rotated to move the slide 39 .to the rig-ht until it is arrested by contactwith the slide 50 which .has been moved rearwardly. The projected slide 50 arresting the rotative movement of v the stop head-causes the carriage to be arrested at the selected columnar position by the c'operation of one of the column stops with one of the stops 24, 25, 26, etc.

The slides 50 are controlled by a series of other, these arms being formed as parts of the bar and pivotedon the pivot rod 54. The universal bar is arranged'in the paths of the-depending arms of the angular levers 53 to be engaged by one of such depending arms at the depression of the associated tabulator key 51. The arms 58' are connected at' their lower ends to r'earwardly extending links 59 which in turn are connected to depending crank arms 60 on a rock shaft 61.. A curved upwardly extending crank arm 62 is likewise fixed to the rock shaft 61 and is connected at its upper end to a link 63 piv-v oted'at 64- to a release lever 65 pivoted at 66 to a bracket fixed to the top plate offthe machine. The forward end of the release lever 65 extends beneath thefeedrack 13 so that a rocking movement .of' the shaft 61 is efi'ective to turn the crank arm 62, thereby pulling downon the link 63 and elevating the feed rack 13 to release it from the feed pinion 14 to free the carriage from control. of the escapement mechanism.. A spring 67 is fixed at one end to a pin 68 and is con:

nected at its opposite end to a crank arm 69 depending from andfixed to the rock shaft Each of these tabulator' keys isv 61. This spring returns th rock shaft '4 and the various parts winne ed therewith to normal position. A carpi rig crank arm 70. is pivoted at T1 to a link to which inturn is pivoted at T3 to the slide 44, so that the. same movement which is effective to release the carriage in the manner hereinbefore described is likewise efi ectivc' to move, the slide bar 39 to the right through the rearward movement of the slide it. inorder to bring the first of the stops (2i) on the stop head 29 into position to cooperate with the column stops.

The features thus far described form no part of my invention except so far they are combined with other features to be hereinafter described. and the tabulating mechanism disclosed may therefore be varied at will.

I have provided means for controlling the speed of the carriage in its travel during tabulating operations when the carriage is freed from the control of its cscapement mechanism and tlZiVtlS in the direction of its feed. The 8])S9tl-COHlii0lllHg inecha iism of my present invention comprises a rack 74 fixed by screws 75 to the bracket arms 20. This rack meshes with a pinion T6 with which it is constantly imiinrained in engage ment. This pinion is fixed to one member of :1 two-part shaft 77: the two parts of the shaft being united by a thread-ed connee tion 78 and bv which the two. parts ofthe shaft are maintained rigidly connected to turn together. The upper section of the shaft extends'throngh a bearing opening of tlie top plate and the lower end of the shaft is received in a stepped journaled bearing 79 in the base 1 of the frame. A long cylindrical drum S0 of comparatively small diamcter surrounds the lower section of the vertically disposed shaft 77. and incloses a radiating arm or blade Sl which is fixed to and protects from the shaft. An upper head 82 is secured to the drum by screws 8 received in tapped openings in the heathwhereas a lower head 84. in a 1:. lie manner. is connected to the. drum by screws 85. Material is contained within tllPt'lOSGtl drum 80 for coiipcration with the arm or blade 31 which latter. under certain conditions to behereinafter pointed out.ina v rotate within the drum. Any suitable material may be employed in the drum to offer a resistance to the blade during the relative turningmovement bctween the shaft 77 and drum 90. I prefer. however. to employ shot. as indicated at 80. or some such erplivalent material for coiiperation with the blade. A stop pin, holding or'locking device 8(5 is received at its thread ed endin the lower head 8%. and projects downward therefrom. This pin. as will be seen from inspection of l i I 5 and a arranged otf to one side of the center of rotationl of'tl'ie drum. The only connection be tween the shaft 77 and the drum is through the blade or arm 81 and the material 80 contained within the drum. The blade 81 cooperates at its upper edge with the upper head of the drum to maintain it against downward displacement on the shaft but a relative movement between the shaft and drum may be effected orthe' drum and shaft may rotate together, the parts maintaining a fixed relation as they turn together.

The shaft 77 is rotated or moves. in unison with the carriage at all times during the travel of the carriage whether the carriage receives a backward or forward movement by reason of the constantly maintained gear connection 7 -l-76 between the carriage and shaft 77. Normally, however, this movement of the shaft 77 is ineffectiveto retard or effect-the movement of the carriage. since the drum 80 is normally carried around with the shaft and is ineffective to retard the carriage. When, however; one of the tabulator keysis depressed to 'release the carriage from control of the escapement mechanism and to throw the tabalator into operation. a rearward ,movementof the slide H is effected. This movement likewise effects a rear ard movement of abracket arm 87 carried by said slide to carry. a stop, holding or locking device 88 thereon into the path of the stop pin 86 on the drum 80, as indicated in full lines in Fig. This is effective to hold the drum against rotation while the shaft 77 continues its rotation and causes the arm81 to rotate within the drum 80, which at this time is maintained fixed. The arm 81 working against the shot- 80 in the fixed drum retards the movement of the carriage and prevents undue shock between the column stops and the stops on the head 29 by which the carriage is arrested. As soon as pressure is released on the depressed tabulator key the carriage is again restored to control of the cscapementmechanism and the tabulator is thrown out of operation. At this time the slide 44 is moved forwardly to the position shown in Fig. 2, thereby moving the stop 88 to the dotted line position represented in Fig. 3 and out of the path of the stop pin 86 on the. drum, thus releasing .the drum and permitting it to rotate freely with the shaft 77. so that no retardation of the carriage is at this time effected.

From the foregoing description it will be understood that the carriage speed-c0ntrolling mechanism of my invention comprises two parts, one of which is constantly in operative connection with the carriage to be moved thereby and the other of which is adapted to move with the first mentioned part or to be held against movement therewith; that when the parts in question turn together no retarding eifect is produced whereas when a relative movement between the parts is effected the mechanism becomes.

operative to retard the carriage in its movement. Moreover, it will be seen that the carriage speed-controllingmechanism is simple in construction, inexpensive to manufacture, effective in use and is not liable to become deranged or, broken or to get out of order.
