Specification of Letters I atent. Patented Nov. 16, 1909.-

Application filed January 6, 1908. v Serial No. 409,500.

To all whom it may concern:

Be it known that I, OSCAR L. INGRAM, a citizen of the United States, and resident of Valla Valla, in the county of WValla Walla and State of Washington, have invented certain new and useful Improvements in Type- WVriting Machines, of which the following is a specification.

My invention relates to typewriting niachines and more particularly to tabulating mechanism and to means for overcoming the shock ordinarily incident in arresting the carriage by the tabulating mechanism.

Une object of my invention is to provide simple and efficient means of the character specified. v

A further, and one of the main objects, of the invention is to provide efficient means for avoiding or overcoming the shock usually incident to arresting the carriage by the tabulating mechanism without decreasing the speed of the carriage from about the time of its release, as when a brake or governor is applied to retard the carriage in its movement to the point of arrest.

A still further object of my invention is to provide means of thecharacter specified which are in the nature of attachments, that may be readily applied to existing forms of typewriting machines.

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 hereinafter specified and particularly 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 vertical front to rear central sectional view of a typewriting machine embodying my invention, parts of the machine being omitted. Fig. 2 is a rear elevation of the machine, parts being omitted. Fig. 3 is an enlarged detail fragmentary longitudinal sectional view taken centrally through the dash-pot. Fig. 4 is an enlarged detail fragmentary rear elevation, partly in section, showing the supports or racks for the column and buffer stops. Fig. 5 is an enlarged detail transverse sectional. view of a column stop bar with a column stop mounted thereon. Fig. 6 is an enlarged detail rear elevation of the same. Fig. 7 is an enlarged detail fra mentary plan view of the parts shown in igs. 5 and 6.

. I have shown my invention embodied in a No. 6 Remington machine equipped with a Gorin tabulator, the invention being readily applicable to such a machine and tabulator without material modification of the structural features thereof.

The frame of the machine comprises a base 1, corner posts 2 and a top plate 3. Upwardly extending lugs or risers 4 and 5 sup port guide rods 6 and 7. A carriage truck 8 carries supporting rollers 9 which cooperate with the guide rod 7 to support the truck for movement from side to side of thasma chine. A rearwardly extending arm ld'projects from the truck and cooperates .at its rear end with the guide rod 6 to support and steady the truck in its movements. Links 11 connect a platen frame 12 to the truck, said platen frame havin a roller 13 at the forward side thereof or cooperation with the shift rail 14 supported in the usual manner for back and forth movements to change the case position of the platen 15 supported on a shaft '16 received in bearing openings in the platen frame. The truck has arms 17 pivoted thereto at 18 and connected at their forward ends to a feed rack 19 which cooperates with a feed pinion 20 mounted on the forward end of a shaft that turns in a bearing 21 secured to the top plate of the machine, the rear end of the shaft being operatively connected to an escapcment wheel 22. Feed dogs 23 are mounted on a dog rocker 24 and cooperate with the escapement wheel, the dog rocker being re-' projects from a frame piece 33- sec'ufed to the base of the machine by screws 34. The rear end of each push rod is connected to an upright tabulator lever 35, the levers being pivoted at 36 to a tabulator frame 37 secured by screws 38 and a supporting piece 39 at the lower end portion thereof to the base of the machine and secured at the upper end portion thereof to the guide rod 6 by a yoke piece 40 connected by screws 41 to the tabulator frame. The upper ends of the levers 35 are bent forwardly to provide denominational tabulator stops 42 which are projected through guide openings in the tabulatorframe. A universal bar- 43 extends across and in front of the upper end portions of the upright levers 35 for actuation by. any of said levers when the denominational stop thereon is projected forwardly.

The universal bar is provided at its ends with supporting arms 44 pivoted at 45 to the sides of the tabulator frame. One of these supporting arms is extended forwardly to provide a release arm 46 which extends above and cotiperates with the rear end of a relem lever 47 pivoted at 48 intermediate its ends to a bracket 49 supported on the top plate of the machine. The forward end of the release lever 47 is provided with a lifting shoe 5O apertured-to receive the feed pinion 20. This shoe 50 projects beneath the feed rack 19 and is free from contact therewith in the normal positions of the parts. When .a tabulator key 29 is moved rearwardly against the tension of the spring 31, the

associated lever 35 will be turned on its pivot- 36 to project the denominational stop 42 at the upper end thereof forwardly. The eflect of this movement isto actuate the universal bar 43, thereby depressing the arm 40 and lifting the forward end of the release lever 47 to'disenga e the feed rack 19 from its feedpinion, t us releasin the carriage and enabling it to travel in tie direction of its feed under the power of a spring drum 51 connected by a band 52 to a depending arm 4 53 connected to the carrier. Projecting upwardly and rearwardly from the carria e truck are bracket arms 54 which ordinari y support the column stop bar, the stops on which are cotiperative with the denominational stops. The construction thus far described is essentially that of a No. 6 Remington machine equipped with the Gorin tabulator and further detailed description is deemed unnecessary.

The usual column stop bar ordinarily employed in the Gorin tahulator may be detached from the brackets 54 and replaced by the supports shown in tthmdrawings and which comprise a supportprianick 55 which corresponds essentially to the column stop bar ordinarily employed in Hie Qorin tabulator. This stop bar is adjusthtilgi'connected to its supporting brackets 54 by. headed screws' 56, each ofwhich passes freely through a slot 57 in the associated-bracket 54 to afford a slight longitudinal adjustment of the rack 55 on its supporting brackets,

the rack being held in its adjusted position when the screws are tightened by the friction between the bracketsand the rack and screw heads. Arranged above the rack 55.

near the ends thereof are su porting or spacto receive upwardly extending projectionson the spacing blocks 58. A headed'screw 64 is received in a tapped opening in each of the projections 63 to prevent the remdval of the rack 61 from the spacing blocks. The lower face of the rack 61 receives a bearing on the upper faces 65 of the spacing or supporting blocks 58'and the construction is such that a relative longitudinal movement may be eiiected between the racks 55 and 61 in the direction of the travel of the carriage. A contractile spring 66 is connected at one end to a pin 67 WhlCh projects from the rack 61, the other end of said spring being connected to a pin or projection 68 on the left-hand spacing block 58. The pres sure of the spring is exerted to normally malntain a fixed relation between the racks or supports 55 and 61, the spring normally holding the movable rack or support in such position that theright-hand end wall of each slot 62 bears against the projection 63 of the associated spacin block. The racks 55 and 61 are each provi ed on opposite sides thereof with square teeth 69 and 70 respec- I tively for cotiperation withdetachable stops 71 and 72. Both sets of stops are the same in construction and the description of one Will apply alike to the other and: but one will be described. Thus from an inspection of Figs. 5, 6 and 7 it will be seen that the stops 72 are each bifurcated at '73 to straddle the at p bar rack or support 61 and to engagc'g: t. the side walls of the bifurcation inthe spaces bet-ween the teeth 70 on the rack. Eachstop has riveted thereto at 74 a leaf spring 75 which at its free end portion extends away from the body of the slot as 1.

shown in Fig. 7, and is formed with a downward projection as indicated at 76 in Figs. 5 and 6. This projection is formed with an enlargement or bent end 77 which, when the ro'ection 76 is received in an o enin be- P l tween. the teeth 70, is adapicd'to engage beneath the corner of one of the teeth as iii is connected at 78 tothe stem-79 of a "provide connnunication between the interior in the head of the cylinder. chamber is closed at one end by a screw 84. provided at its inner end projection 85, against rests upon a valve seat 87 formed at the :into a laterally extending opening in the .the normal position through the opening against its valve seat automatically displace the ball valve 86 anunication from the interior of the cylin- -der to the outer air through the passage 89 -to enable the erases shown in Figs. 6 and 7 to prevent an accidental detachment of the stop from the rack. The column stops 71 andstops 72, which latter will be hereinafter referred to as butfer stops, are arranged one set above the other in close proximity as shown in Fig. 1 so that both sets of stops .may cooperate, with each of the denominational stops 42 when it is projected forwardly.

From an inspection of Figs. 2 and 3 it will be seen that the right-hand end of the rack piston 80 which Works in a cylinder. 8l,:there being suflicient space between the edge of the piston and the inner wall of the cylinder to allow a slight leaka e of air )ast the piston. The cylinder 81 is fixed to the column stop bar 65 by the right-hand screw 56 which secures the stop bar 55" to the associated bracket arm, the end of the screw 56 being received in a tapped opening in the cylinder.

The cylinder headis perforated at 82 to oft-he cylinder and valve chamber 83 formed The valve with a reduced. which a ball valve 86 is adapted to beer in the normal disposition of the parts. The ball valve 86 normally upper end of a hollow screw 88 threaded.

cylinder head to form a passage-89 between When the stops 71 and: 72 have the interior of the cylinder and the outer air, said passage being normally closed by the valve or ball-86. It will be seen that in of the parts the ball valve 86 bears against the projection on the scrcwSl so that itcannot be displaced from the valve seat by air pressure passing.

S2 in the cylinder head. The construction is such that a movement of the piston toward the cylinder head tends to force the ball valve with a greater pressure to prevent the escape of air from the interior of the cylinder through the passage 89, althoughat this time there will be a slight leakage of air around the edge of the piston. When the piston moves in an opposite direction in the cylinder the suction produced therein will from its seat, thus providing a free compiston to be quickly returned to its normal or outermost position in the cylinder.

The construction thus described constitutes a cushion, or more specifically considered an air-cushion or dash-pot which is adapted to receive the impact of the carriage as' will. hereinafter'more clearly appear.

From certain aspects of my invention it is immaterial what character of cushion is em ployed, the WOI'( cushion being used in a broad sense althou h I prefer in practice to employ an air-cush on or dash-pot as shown.

In the use of the devices a number of butler stops stops used. Thus in the present instance two column stops are two butler stops 72-are likewise employed, each bufier stop being situated to the left of the column stop with which it 'is'into be employed. Of course, the adjustment of the column stop will depend tended upon the position of the columnar field to be written and the buffer stops 72 are ad-l justed according to column stops, and the distance that each bufier'stop is normally situated from the associated column stop determines the amount of absorption of the energy of the carriage before it is arrested by the column stop, as will hereinafter more clearly appear. been adjusted in themanner described and the tabulator key 29 is pushed rearwardly, the associated denominational stop 42 will be projected forwardly into the paths of both of the sets of stops 71 and 72. Since each of the stops 72 is situated to the left of its associated column stop 71 it will, however, be brought into contact with the projected denominational stop before the can cooperate therewith. When an engagement between av stop 72 and theprojected denominational stop takes place the stop 72 and the bar 61 on which it is supported is arrested while the carriage continues its movement. The relative movement thus efi ected between the carriage and stop bar 61 is etl'ectiv to bring about a movement. of the piston head 80 n1 the cylindcr of the dashpot, thuscushioning and absorbing the impact of the carriage. The relative movement between the racks (31 and 55 continues until the column stop just to the right of the engaged buffer stop is brought into contact with the projected denominational stop and the carriage is brought to rest by an easy movement without shock or jar and without. liability of injury to the parts. As the denominational stop is withdrawn after the arrest of the carriage has been effected in the manner described, the feed rack reengagcs the feed pinion to hold the carriage against further free movement and as the buffer stop {72 is disengaged the spring (36 will quickly move the rack 61 back to. its normal positionj the dash-pot, bypeasoh of the automatic action of the valve 86, atthis time offering no obstruction to the relative movement of the racks 55 and 61. v

From the foregoing description itwill' .be

the adjustment of the- '70 7 2 are preferably employed which correspond to the number of column I shown in'Fig. 2 and column stop i 40 it should be understood that this term is stop may be situated at a greater distance,

from the column stop than would be required when a column stop is situated in a position to afiord only a comparatively short run of the carriage. The effect of the buffer or cushion may thus be nicely regulated for each of the column stops without afiecting the cushion or dash-pot itself except that the pistonwill receive a longer or shorter travel in the cylinder according to the relative adjustment between the difierent-stops 7 2 and their associated column stops 71 and according to the force of the impact of the carriage and the extentof travel thereof be fore it is arrested by the cooperation of a butter stop with the projected denominational stop. I

From the foregoing description it will be understood that the bufier stops may each be said to constitute an impact device for cooperation with a denominational or tabulator stop 42 and that each of the impact devices or stops 72 is supported'by a cushion;

that a cushion or dash-pot tends to resist a relative movement or displacement between the racks or. supports '55 and 61 from the normal position, but does not resist the relative movement between said parts back to normal position so that the parts may be quickly restored to their normal relations.

While 1 have referred herein to a carriage employed in a broad sense and is intended not only to'cover a platen carrying carriage I of the style shown, but also to cover all styles of carriages whether of the general character shown or those ordinarily employed in flat platen machines.

From a broad aspect each of the stops +2 constitutes a tabulator stop. From a more specific aspect each of said stops is a denominational stop; Each of the stops 71 is a tabulator stop considered from a broad aspect. From a more specific point of view each of said stops is a column stop and in the accompanying claims thesedistinctions have been recognized.

While I have shown and described in specific detail one form ot construction embodying my invention, it should be understood that various chainges may be made without departing'from the invention.
