TYPE-DISTRIBUTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 467,087, dated January 12, 1892.

Application file'd March 27, 1889. Renewed December 5, 1891. Serial No. 414.192. (No model.)

To all whom it may concern:

Be it known 'that we, LORENZO DOW and DANIEL POWERS, citizens of theUnited States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain newand useful Improvements in Type- Distributing Machines; and we 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.

Our present invention relates particularly to improvement upon the type-distributing machine invented by Lorenzo Dow, one of the present inventors, and embodied in his patent, No. 394,255, of December 11, 1888, and embraces modifications of the method of operating the gate shown in our application for patent, Serial No. 304,943, filed the same day with this application, on which Letters Patent No. 430,007 were issued June 10, 1890.

Figure 1 is a vertical cross-section showing mechanism for operating the gate. Figs. 2 and 3 are details illustrating the same. Fig. 4 is a perspective view illustrating the means for operating the gate. Fig. 5 is a detail of the same. Fig. 6 is a detail of the hammer and gate.

- In the method shown in our application, Serial No. 304,943, and the aforesaid patent issued thereon, the movements of the hammer and gate were made to nearly conform to sixty sizes of type-bodies. In the one we now show the thickness of the bodies has been arranged in nine classes, so that nine differentsized openings and nine different adjustments of the hammer suffice for ejecting the entire number of type to be distributed. To illustrate, the lower-case letters f i j are in thickness in minion type between .032 and .038 and t s v between .041 and .047. If we call the first-named class No. 1 and the second class No. 2, it will be seen that if one adjustment of the hammer and gate would suffice to expel all the letters of its classNo. 1, for instance-it would simplify the mechanism necessary to effect this. All the other letters, figures, and marks can be made to fall within one or another of these nine classes. The lettering of the drawings in this case corresponds with that of the drawings in my other case above referred to. The frame is designated by letter A, the type-channel by letter D.

In Fig. 1 is shown a piece M, attached to the frame A by the screw as above the levers of the key-board and between the keys H and the upright shaft I This supports one end of nine small shafts, and the other ends of these shafts are supported by another similar piece attached in the same manner, as M, to the frame A, so that the shafts M extend across all the levers of the key-board and at right angles to them. At M is seen the arm m, attached to to the shaft M. Suppose this shaft is designed to move the gate and hammer for the letters we have called Glass 1, whose thickness is between .032 and .038 of an inch. For each lever of the keyboard operating to expel a letter of this class, as t, is an arm m, as seen in Figs. 1 and 2. The piece m is pivoted to the key-lever H at m It has an arm projection m Fig. 2. The upper end of m is bent like a hook to pass over the arm m near its free extremity. The depression of the key-lever H would of course carry down the piece m and the free end of the arm m, partially rotating shaft M. A coiled spring on shaft M (shown at Fig. 5) returns the shaft M to the position shown-in'Fig. 1, when the key is released by the finger. From other side of shaft M projects the arm m, which at its outer end m is pivoted to the upright pin m. It is obvious that on the depression of the key-lever effecting the partial rotation of shaft M, as explained, the arm m moves up and carries up the pin m, wedge-shaped at its upper end and as seen in Fig. 1. This pin passes through an opening in the frame A to the upper surface of an opening in a small plate m attached to the frame A, which serves as a guide to said pin. The upper extremityof this pin or stands just below the surface of the plate m Upon plate on lies another m held at one end in position by the pin 0 working in a slot and the other pivoted to lever -vpiec-e H which carries the gate. This plate has openingsor holes to correspond with those in plate m into which the pin m enters, when the depression of the key-lever H causes'it to rise. The holes in the upper plate on are so adjusted with reference to the wedge-shaped end of the pin on that, entering the hole in the upper plate, it draws it back the distance required to open the gate. Each of the nine shafts M actuates a pin, and the wedge end f of each pin actuates the plate m to open the gate sufficiently to allow the letters of the class to which it is adjusted to pass out. Each shaft M is connected by the arm on and the piece m to all key-levers II, that operate the letters of its class. It will be observed that lever-piece II carries the automatically-adjustable hammer II and the lever-piece H the gate S, and thatthe movement of these two pieces is over the same distance. It, then, these two pieces are connected together, so that the movement of one wouldcause a corresponding movement of the other, the gate and hammer would automatically assume the nine positions required to eject the nine classes of type. Since the supplemental key H, Fig. 1, operates to open the gate for capital letters whose bodies are thicker than the corresponding lower-case letter which key H operates to eject, these two keys must operate in nearly all cases shafts M belonging to different classes. The depression of supplemental key I-l carries down with it in all cases the key H operating the lever H and, unless the piece m were disengaged from the arm m when the supplemental keys were depressed, two levers would be actuated and two pins attempt to operate upon plate m at the same time. This would defeat the attempt of the operator to eject the end type. It will be seen in Fig. 1 that the short lever H is not connected to the same shaft M as is lever H and therefore actuates a different pin m". In Fig. 2 it will be seen that the piece m is an arm of a bell-crank lever, pivoted at m the other arm of which an is actuated by a pin n in the short lever H Figs. 1 and 4. In Fig.1 it appears that the supplemental key II stands just above H while key H is moving down this short distance, carrying lever I1 The pin a operates upon the short arm m, Fig. 2, of thebell-crank lever m to depress it and throw the long arm m forward and off from the end of m, as seen in Fig. 2. This release of arm m allows the supplemental key H to actuate its own arm a through the link n, pivoted to the short lever ll", as described.

01 is a small spring which returns the arm m to the position seen in Fig. 4 when the keys H and II have returned to the position shown.

Having now described our invention, what we claim is l. The combination of the automaticallyadjustable hammer H and pivoted pieces ll and 1-1 gate S, the sliding plate m plate m with the pin 172, all operating together substantially as described, and for the purposes set forth.

2. The combination of the automaticallyadjustable hammer II, pivoted pieces 11 H the sliding plate m plate m with the pin m, the arm m, mounted on shaft M, arm 711, piece m and key-lever I'l substantially as described, and for the purposes set forth.

3. The combination of key-leverll", pin a", with the bell-crank lever m and m", the arms m and m, mounted on shaft M, and pin on", substantially as described, and for the purposes set fort-h.

4. The combination of the automaticallyadjustable hammer H, pieces 11 H and gate S, the sliding plate m and plate m with the pin m, the arm m, mounted on shaft M, arm a the link 11;, and key-lever H substantially as described, and for the purposes set forth.

In testimony whereof we affix our signatures in presence of two witnesses.

LORENZO DO\V.
