ALBERT D. VINFIELD, AND BEN- WORD-REGISTER FOR TYPE-WRITING MACHINES.

SPECIFICATION forming part of Letters Patent No. 584,715, dated June 15, 1897.

@ Application filed April A, 1896.

T at whom it may concern.-

Be it known that I, CORNELIUS O. E. VAN ALsTINE, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in \Vord- Registers for Type-lVriting Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same.

The object of the invention is to provide a device for registering the number of words written by a type-writer and to enable the operator to ascertain by a glance at the indicator just how many words or folios have been written or what amount of work has been done by the machine.

lVith these objects in view the invention consists in a novel construction and combination of parts of a word-register for typewriting machines, as will be hereinafter fully described and claimed.

I have illustrated my invention in the acz 5 companying drawings, in which Figure 1 is a View in end elevation of the register showing the means for connecting it with the space-bar of a type-writin machine. Fig. 2 is a view in plan. Fig. 5 is a 0 view in longitudinal section, on an enlarged scale, taken on the line as m, Fig. 2. Fig. 4.- is a view in transverse section, on an enlarged scale, taken on the line y y, Fig. Fig. 5 is a View in side elevation of a type-writing ma- 3 5 chine, partly broken away to show the manner of connecting the register with the space-v bar of the machine. of the same.

Referring to the drawings, A designates a stand or support for the registering device,

and mounted in suitable bearings on this support is a worm-shaft B, to one end of which is secured a lever E, connected at its outer end by an arm F in any suitable manner with the space-bar R of the type-writing machine and at its inner end by a tension-spring b with the base of the stand A.

A tension-screw M is screwed into one end of the worm-shaft B, and a spiral spring M is placed around the neck of the said screw be- Fig. 6 is a view in plan Serial No. 586,174. (No model.)

tween the head thereof and the stand A for the purpose of preserving the proper tension between the worm-shaft and the worm-wheels J and K.

The lever E is provided with a pawl 1), adapted to engage the teeth of an index ratchet-wheel D, secured to one end of the worm-shat t B, a spring 1) serving to keep the pawl in engagement with this ratchet-wheel, and arranged below this wheel D and working in a guide g 011 the stand A is a vertically-disposed pawl or catch g, which is held normally in engagement with the ratchetwheel by means of a spring g and operates to prevent backlash thereof. Arranged adjacent to the stand A is a bracket G, having a vertical slot h therein, in which regulating stop-pins 7L are secured to limit the sweep of the arm F and lever E, to which it is secured. The spring b at the outer end of the lever holds it and the arm F normally up against the upper stop-pin h, which is secured by a nut in the slot 71 and when the arm F is forced down by the operator striking the space-bar R it contacts with the lower regulating stoppin h and is thereby regulated in its movement.

hen the lever E is moved by the motion of the space-bar, the pawl Z) thereon moves the ratchet-wheel D a distance equal to one tooth and at the same time rotates the wormshaft a short distance, and when the spacebar is released the tension-spring b causes the lever E and arm F to resume their normal positions. The ratchet-wheel D is here shown as provided with fifty teeth; but the number of teeth may be increased or diminished ac cording to the requirements of the case. In this instance the wheel K has one hundred teeth and the wheel J one hundred and one teeth.

The worm O of the worm-shaft engages the teeth formed in the periphery of the two index wormwheels J and K, which are arranged one above the other in a worm-wheel holder C, supported on the stand A. The worm and worm-shaft are incased or covered except at the point where the worm-wheels engage the worm, by which arrangement they are effectively protected from dust and dirt.

The worm-wheels are each provided with a hub, the hub of the upper wheel. K fitting snugly around the upward-extending hub of the lower wheel J, a stud (1, extending through the hub of this latter wheel, serving to hold the two wheels in operative position with relation to the worm. The opening in the holder 0 through which the stud (1 passes is oblong in order to permit of the worm-wheels being moved to or from the worm to effect the proper adjustment between these parts, a nut (Z on the lower end of the stud serving to hold the stud in its adjusted position.

Fitting around the hub of the upper wormwheel K is an inverted saucer or dish-shaped dial-plate L, which is held in place by a lockring (i sprung into an annular recess formed in the hub of this wheel the wheel K being held in place by a lock-ring d sprung into an annular recess formed in the hub of the lower worm-wheel J, which projects above the hub of the wheel K for this purpose. An indicator-finger c fits around the hub of the wheel J and rests on a shoulder formed thereon and is held in place by a lock-ring d sprung into an annular recess in the upper portion of the hub of the lower wheel J. The dial is provided with a stud 7, by which it may be turned to set it by moving it to the starting or zero point. In addition to the indicator-finger 0 there is a second finger 0, secured to the edge of the shell or worm-wheel holder 0, the function of which will presently appear. The lower wheel J drives the finger c and the upper wheel K drives the dial L.

The dial L bears two graduated circles, the enter one of which registers the hundreds and the inner one the thousands, the finger c pointing to the outer circle and the finger c pointing to the inner circle. As the lower worm-wheel J has one more tooth than the upper worm K, when the latter has completed one revolution the former has gone one tooth farther and the finger 0 will indicate or point out one space on the inner circle of the dial, which means that as many words have been registered as there are indicated by the finger c or that ten thousand words have been written. The fingerc, having indicated ten spaces or ten thousand words, will begin again at zero, and so on. It is obvious that when the ratchet-wheel D has fifty teeth I can register up to five hundred thousand words. If the wheel D has one hundred teeth, I can register one million words.

The register maybe secured on either side of a type-writingmachine, or it may be placed behind the same, or it may be a detachable and complete piece of mechanism, which may be attached to and detached from a typewriting machine at will-as, for instance, by a rod H, Fig. 1. \Vhether the attachment of the device to the machine be permanent or otherwise is immaterial, as either may be adopted without departing from the spirit of the invention. The lever E is provided with a slot 6, and a screw c is passed through this slot and through the arm h, securing the arm and the lever in any desired position along the slot 0, which permits of adjustment of the arm l according to the height of the typewriting machine space-bar, as shown in Figs. 1, 5, and 0.

llaving thus fully described my invention, what ll claim as new, and desire to secure by Letters Patent, is
