Specification of Letters Patent.

Patented May 16, 1%11.

Application filed February 3, 1910. Serial Ho. 541,943.

To all whom it may concern:

Be it known that I, JOHN T; Sorraarr, citizen of the United States, and resident of Vashington, in the District of Columbia,

have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

' My invention relates especially to tabulating mechanism for typewriting machmes and the main object of said invention is'to provide an improved and simple column selecting mechanism which enables the traveling element or carriage to be released and moved to a predetermined one of a plurality of columnar positions, any intervening columnar positions being skipped or passed.

To the above and other ends my invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

One form of my invention is shown in the e accompanying drawings wherein clear understanding of said invention.

. cal sectional view taken on a plane represented by the dotted line 'z -g of Fig. l and looking in the direction of the arrows at said line. Fig. 4- IS an operating view of the column selecting mechanism. Figs. 5 to S inclusive are fragmentary views showing the normal relation between the various column selecting levers and the part moved by said levers and controlling the variably movable frame stop. Fig. 9 is a perspective view of the column stop bar and column stops thereon. 1

In the various views parts are omitted and parts broken a\ my.

\Vhile my invention is shown adapted to a front-strike typewriting machine of the Yost visible style, it is to be understood that said invention is applicable in whole or in part to other styles ofwriting machin s i In the present instance the main frame of the machine comprises side plates 1a a back plate 2, a fore top plate 3 and a. rear top plate 4, the top plate parts or sections being spaced apart to provide room for a carriage comprising a truck 5 and a shiftable platen frame 6, which frame is connected with said truck by links 7 and carries a platen 8. The truck 5 is provided with grooved rails. 9 which cooperate through anti-friction balls 10 with fixed grooved track-ways 11. The carriage is connected by a band 12 with a spring drum 13 pivoted on brackets 14 depending from a stationary frame bar 15. Said spring drum constantly urges the carriage leftward, leftward motion being controlled by devices including a horizontal feed rack 16 supported by arms 17 pivoted to the carriage at 18 and depending from the underside thereof so that the rack bar may be swung fore and aft of the carriage. The front edge of the rack bar is toothed and said rack bar is normally held in the Fig. 1 position by a spring-pressed plunger 19 on the truck 5, said plunger pressing down on a branch 20 of an arm 17, the normal position being determined by a stop pin 21 which cooperates with another branch of said arm 17. The feed rack normally meshes with a pinion on the upper end of a vertical shaft 2-l journaled on an arm 25 fixed to the frame bar 15, the lower end of said shaft being journaled on an adjustable stud 2G threaded through an ear on astationary frame bar 27 supported on the frame plates 1. The escapement wheel 28 is operatively connected with the shaft and is adapted to cooperate with the usual or suitable feed dogs (not shown) which are controlled by printing and spacing keys. The shaft 2st carries a cylindrical housing 29 which contains or may contain pawl and ratchet mechanism, which, while connecting the escapement wheel with the shaftduring the advance of the carriage left-ward, permits rotation of" the shaft independently of the escapement wheel during returnmovements of the car-' riage. The latter, of course, is normally under the control of the feeding or escape. 100

ment devices whereof the escapenient wheel, is an-element. i The mechanism for releasing the carriage comprises a shoe 30 formed on the upper end of a lever arm 31 secured to a. rock shaft 33 105 journaled on a bracket 3 depending from the frame bar 15, said shoe standing in front of the feed rack 16. The rock shaft 33 has fixed to it a forwardly projecting arm 35 which is connected by a link 36 with the universal bar of the column selecting mechanism, as presently to be described. By raising the link 36 the shoe 30 is swung rearward, thereby disconnecting the feed rack from the pinion.

The tabulating mechanism comprises a toothed stop bar 37 supported on two brackets 38 and 39 which are secured to the carriage truck 5 by screws 40. The stop bar 37 is rectangular in cross section and is slidably mounted so that it may move to a limited extent lengthwise of and relatively to the carriage for the purpose of diminishing the shock due to the impact against a frame sto 3 of one of the column stops carried by sai bar. The slidable mounting comprises a piston head 41 fixed to the right-hand end of the stop bar 37 and cooperating with a fixed cylinder 42, a coiled spring 43 being interposed between the piston head and the head of the cylinder. The construction thus briefly described is in the nature of a dash pot and is more fully set forth and is claimed in my co-pending application Serial No. 525,698, filed November. 1, 1909. The stop bar 37 is notched or toothed at its forward and rear faces, the interdental spaces being a letter space distance apart as is'common and adapted to receive adjustable column stops of which four are shown in the resent.

instance and numbered from left to right 44,

' 45, 46 and 47. Each of these column stops comprises a notched or bifurcated sheet metal strip or plate having an angular stiffening flange and which may be. arranged to straddle the stop bar 37 between the teeth thereof at any desired point, said column stops ,being slipped on said stop bar from above. Each column stop has an edge portion bent off at right angles to form a stiffening flange 48 and is provided with a depending portion or lug which constitutes the stop portion proper of the stop. T hose lugs are separately numbered. for convenience of description as 4-11, 45, 46 and 47 As will be apparent from Figs. 1, 4 and 9, they all terminate in a single horizontal plane but are out of line with one another, each moving in a different path, all the paths being parallel. In the present instance the lugs or stops proper are so disposed that they leave an openspaec 3 directly beneath the stop bar, the stop lugs 44 and 46" being forward of said open space While stop lugs 45 and 47 a are back of the same.

Adapted to coiiperatc with the column stops is a frame stop or column selecting stop in the form of a flat plate-like arm 49 which extends upward through a hole in. the top plate 4 through a notch 50 in a guide plate 51 secured to the upper face of said top plate by screws 52. The stop arm 49 is arranged edgewise in the direction of carriage travel and normally its upper end or stopping portion lies in the open space or pathway .9 as best shown in Flg. 1 and so that a forward or rearward movement will bring it into the path of one or'another of the column stop lugs. Thesto arm 49 extends downward, it bein slight y curved or offset rearward and is etachably secured at its lower end by screws 53 to a seat formed at the upper end of a lever frame 54, said frame inclining downward and forward and being pivoted on pivot screws 55 which are supported on the arms of a bracket 56 fixed to and depending from the frame bar 15. As best appears in Fig. 3 the lever frame is arranged between the arms of the bracket 56 and below the pivot screws 55 is bifurcated to provide two branches or arms 57, said arms terminating at their lower ends in hubs which support a cross rod 58, said cross rod connecting the arms 57 of the lever frame.

The lever frame 54 and stop arm 49 are adapted, to be variably controlled through the cross rod 58 by column selecting levers of which four are shown in the present instance and numbered respectively '59, 60, (i1 and 62. These column selecting levers are of thefirst order and are arranged side by side and'extend fore and aft of the machine, being seatedin vertical notches or kerfs 63 formed in a lug or downward extension 64- from the underside of the frame bar 27. 16ers 65 projecting forward from the frame bar 27 are spaced apart as shown in Fig. 2 and support pivot pins 66.which are secured in place by screws 67 and proa vertical key stem 69, which is guided by.

fixed guide plates 70 and 71, each key stem terminating at the top in a finger key or.button 72. The keys 72 are arranged in a row above and behind the lastrow of the regular set of keys and the top of each key 72 may be suitably marked. 'As shown in Fig. 2 the top of the key associated with the lever. 59 is marked with the numeral 1, while the.

keys associated with the lovers 60, 61 and 62 f are marked respectively with the numerals 2, 3 and 4. The rear end portion of each of the column select ng levers where 1t underlies the cross rod 58 is widened somewhat as indicated at 73 and back of the widened portion 73 each lever is rovided with an upward extension or finger 4; which is bent rearwnrdiy at its top and has secured to it the upper end of a coiled restoring ceases I rocked on its fulcrum, the rear arm of said lever being raised so that it stretches the spring and lifts the upper edge of the thickened portion 73. of said'lever toward the cross rod 58. Said upper edge of each lever is formed with a cam slot, these cam slots varying in direction and inclination, as will be clear from Figs. 5 to 8 inclusive;

but the mouths of the cam slots being in line and normally underlying the cross rod 58 so that when raised separately they may engage therewith. The cam slot 76 in the lever 59 inclines downward and rearward at such an inclination that when the lever 59 is operated and the cam slot engages with the rod 58, it will cam. said rod rearward to the extent shown by the dotted line position of said rod in Fig. 5. The cam slot 77 in the lever 60 inclines oppositcly to the SlotT-G so that said slot 77 is adapted to swing the cross rod 58 forward to the dotted line position in Fig. 6. The cam slot 78 in the lever 61 is directed rearward like the l cam slot 76 but ata lesser inclination, while the cam slot 79 in the lever 62 inclines forward but at a lesser inclination than the other forwardly inclined cam slot 77 so that itwill swing the cross rod 58 forward to a lesser degree. The construction is such that the cam sloti'ti will cotipcrate with the rod 58 to swing the lever frame 5. on its tul- .crum and throw the stop arm 48 forward into the path of the column stop lug 44 The cam slot '78 will operate to throw the stop arm a9 forward to a lesser extent and into the path of the stop lug 46 while the two cam slots 77 and 79 will operate to swing the stop arm ll) rearward different extents and so that it will cooperate respectively with the column stop lugs 415*- and 47.

The. actuation of the column selecting levers not only variably actuates the stop arm 49 so as to move it different extents int-he arcuate path towhich it is confined, but.

also lifts the link 36 to effect the release of the carriage through devices comprising a bail-like universal bar men'iber 80 which overlies the column selecting levers forward of the cam slots therein, said universal bar rearwardly extending angular arm 80 is fixed centrally to the universal bar frame 80 and is connected to a restoring spring 81 anchored to the bracket After the detailed description of my improvements heretofore given it is not deemed necessary to enter into a further extended explanation of the mode of operation. In Fig. t the parts are shown in operative or abnormal positions resulting from the actuation of the fourth column selecting key which operates through the cam slot 79 to swing the stop arm 49 rear ard into the path of the column stop lug 47 and also to release the carriage so that the same may run freely leftward until arrested by the.

co-action of the stop 49 with the stop lug 47, the stop 49 being held locked in co-acting position by the engagement of the bottom of the slot 79 with the cross-rod 58 as long as the column keyis held depressed. During this leftward run the intervening column stop lugs whose paths are not obstructed by the frame stop 49 will be skipped or passed. It will. lac-understood that a similar actuation of any of the other column keys will move the frame stop to a different extent and cause its co-action with that one of the column stops which corresponds with the actuated column key. The arm has a cam notch which acts on the rod 58 to return the frame stop always to normal position and hold it therein.

It will be seen that my invention provides a simple and effective column selecting mechanism which is rapid and certain in operation and which is adapted to v' ariousstyles of work, such for example, as writing in the date, name and-address and thesalutation, etc, in letters, or the name and address "on onvelops as well as for form or tabular work of various kinds.
