WORD-METER FOR TYPE-WRITERS.

Specification of Letters Patentl Patented Feb. 10, 1914.

Application filed April 22, 1913. Serial No. 762,968.

To all whom it may concern:

Be it known that I, WARREN B. \VIN'rnns, a citizen of the United States, residing at Stephenville, in the county of Erath and State of Texas," have invented'certain new and useful Improvements in ord-Meters for Type-\Vriters; and I do hereby declare thefollo'wing to be a full, clear, and exact descrlptlon of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference eing had to theaccompanying drawings, and to the letters and figures of reference marked thereon, which'form a part of this specification.

This invention relates to new and useful improvements in apparatus for recording the number of words written upon a type- .Writer and comprises a simple and efficient device of this nature having various details of construction and combinations and arrangements of parts which will be hereinafter full described, shown in the accompanying rawings and then specifically defined in the appended claims. I illustrate my invention in the accompanying drawings, in which Figure 1 is a side view of a typewriter showing the application of my invention thereto. Fig. 2 is a similar View showing a rack member held down to its lowest limit. Fig. 3 is a sectional view transversely through the apparatus. Fig. 4 is a detail sectional view on line 4=4 of Fig. '1, and Fig. 5 is a sectional view on line 5-5 of- Fig. 1.

Reference now being had to the details of the drawings by letter, A designates the frame of an ordinary ty ewriter with the usual key'levers 'B pivota 1y mounted at B" and a spacing member C.

.A rack member D has arms D at the ends thereof which are pivotally mounted upon 7 .the projecting ends of the rod E journaled in the opposite walls of the frame and a coiled spring F is fastened at F to an arm D and its other end is fastened to .a pin H upon the frame, the purpose of said spring being to normally holdthe rack in its highest position as shown in Fig. 1, so that the cross-piece of the rack will be positioned underneath the various key levers and adapted to be rocked by a depression of any one of the keys.

A hook G is pivotally mounted upon a pin I upon the frame and is adapted to be held in the path of the upwardly projecting end D? of the rack by means of a coiled spring J. A rod L is fastened at one end to the hook Gr and its other end to the arm N of the collar N which is fastened upon a shaft 0 earned by the frame. Said collar is provided with a second finger N which is adapted to en age underneath the spacing member C.

Mounted upon the stub shaft M, fixed to the frame of the machine, is a gear wheel Q which is in mesh withv a pinion Q, which s loosely mounted upon the'shaft R, andlt 1s a pivotal pawl mounted upon the pinion Q. and is adapted to engage ratchet teeth R upon the shaft R, causing the shaft to ro-' tate in one direction when the loose pinion Q is driven inone direction, said pinion turning idly when rotated in the opposite dlrection. Fixed to the end of the shaft R is a spur wheel T, shown in Fig. 5

of the drawings, the fingers of which are adapted to engage and tilt the lever S which is pivotally mounted upon a pin .S, one end of said lever S being pivotally connected at S to the rod L, shown in Fig. 1 of the drawings.

A rod is connected at its lower end to one of the arms D and its upper end to a crank arm P fixed to the meter shaft P of the meter P thus affording means whereby, at each revolution of the rack, a recording may be made upon the meter.

The operation of my invention will be readily understood and is as follows: \Vhenever a key lever is depressed, it will come in contact with a rack, causing the lever P to be pulleddown effecting a registration upon the meter. -As the projecting poition D of the arm lowers below the upper end of the hook. G, the spring J will cause said hook to be drawn over the top of said projection D in the manner shown in Fig. 2 and hold the rack down until released. The releasing of the hook D is accomplished by the depression of the spacinganelnber C which, coming in contact with the finger N will cause the collar 0 t0 rock'and tlie arm N which is connected through the medium of the rod L with said hook will draw the latter outward to disengage the same from the rack and the spring F will return tlte rack to its normal position. This operation is repeated every time a word is spelled and the same spaced. This operation is repea ted for each word of the line but, as the space bar is not depressed at the end of line, the

first word in the second line will be registered by the mechanism which shown in l and 4: of the drawings. When the carriage starts to return to its starting position, the gear wheel Q will cause the pinions to rotate and the pawl carried by the latter engaging the ratchet teeth upon the shaft R will cause the same to rotate in one direction. The spur wheel upon the end of the shaft R, coming in contact with the upper end of the lever S, will cause the same to tilt and which will draw the hook G from engagement with the rack and allow the same-to return to its farthest upper limit in readiness to be operated by the next depression of the key lever. When the space bar is depressed and the rack is released, the latter will assume the position shown in Fig. 1 of the drawings and the finger N of the collar N will be out of the path of the spacing member as the end of the hook will be held by the spring in contact with the edge of the upright port-ion D of the .arm D. Thus it will be seen that the spacing bar may be depressed as many times as may be desired without effecting the registration, it being necessary to first depress a key lever in order to effect the registration.

The gear wheel Q, may and preferably is an independent wheel, as shown in the drawings, but, if desired, the tension wheel of the typewriter may be geared and substituted for the typewriter wheel shown.

In order to provide for the recording of figures when the tabulating keys of the machine are used, the type bar of the tabulating key is provided with a lateral extension adapted to engage the spacing bar or its connections. 4

What 1 claim to be new is-:-

1. A word meter for typewriters compris ing, in combination with the frame of a typewriter having a series of key levers and a spacing member mounted thereon, a meter, a rack positioned underneath the levers and adapted to be rocked by a depression of any of said levers, connections between the rack and meter, a springpressed hook pivotally .rack positioned underneath the levers and adapted to be rocked by a depression of any of said levers, connections between the rack and meter, a spring-pressed hook pivotally mounted upon the frame, a rocking member with fingers, one projecting underneath the spacing member and the other having connection with said hook, a shaft actuated by the typewriter carriage, a spur wheel fixed to said shaft, and a lever carried by the spur wheel and having pivotal connection with the hook, as set forth.

3. A word meter for typewriters comprising, in combination with the frame of a typewriter having a series of key levers and a spacing member mounted thereon, a meter, a rack positioned underneath the levers and adapted to be rocked by a depression of any of said levers, connections between the rack and meter, means for holding the rack depressed, mechanism for releasing the rack as the spacing member is actuated, a gear wheel actuated by the carriage of the. typewriter, a shaft ournaled in the frame, a pinion loosely mounted upon the shaft and in mesh with the gear wheel, a pawl carried by the pinion wheel, a ratchet wheel upon the shaft engaged by the pawl, a spur wheel fixed to the shaft, a lever 'pivotally mounted upon the frame and having pivotal connection with said hook and adapted to be tilted by said spur wheel, as set forth.

In testimony whereof E hereunto alfi); my

signature in presence of two witnesses.
