SPECIFICATION forming part of Letters Patent N o. 624,454, dated May 9, 1899.

Application filed January 6, 1899.

To all whom, it may conoci/'71,: l

Beit known that we, LEO MILLER CHAPMAN and JAMES MADISON GELATT, citizens of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Linotype-Machines, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to linotypemachines, and is an improvement on the usual vise-jaw-adjusting devices ordinarily employed in such machines to determine the measure of the type to be composed and The machine of this class now in use and to which our improvement relates is shown 'in the patent to Mergenthaler, No. 557,000. In this machine as Ordinarily constructed, in practice, when it is desired to change the measure or determine the number of ems which shall govern the setting up of the type it is necessary to employ a screw-driver and remove a setscrew and also to adjust and operate a wrench on the screw-shaft whichl bears the adjustingnut. In our improvement we do away with the set-screw and the use of a wrench. Another method employed to this end is the placing of type-blanks between the adjusting-nut and the jaw, which often causes trouble and delay. This method we also dispense with.

Our improvement 4is fully disclosed in the following specieation, of which the accompanying drawings form a part, in which like numerals of reference refer to like parts in the several views, and in which- Figure l 'is a side sectional elevation of a portion of a linOtype-machine, showing the vise used in determining the measure of the type and the means employed to change the measure, part of the machine being shown in full lines and the screw-shaft being shown in dotted lines; Fig. 2, anend elevation showing the adjusting devices".

2, looking in the direction of the arrows. Fig. 4 is an end view of the flange-piece shown in Fig. 3, and Fig. 5 is a side View thereof.

Referring Inore particularly to Fig.` 1 of the drawings, 7 is a base-block mounted in the front portion of the linotype-machine and adjacent to the type-metal pot. is constructed in the usual manner, the details of construction being therefore not Shown and described, and is chambered to receive the vise-jaws 8 and 11, which are adjustable longitudinally thereof and one of which, 1l, is slidably mounted thereon and the position of which determines the measure of the line of type to be setup between them, as usual. x

A bracket 13 (seen in Figs. l and 2) is secured to the base-block 9 by means of screws or bolts 14, (best seen in Fig. 2,) said screws passing through a plate or block 15, integral with said bracket 13. A screw-shaft 10 is journaled at one end in the bracket 13, as at 17 in Fig. l, and the other end is supported bya correspondingly-threaded adj usting-nut 12 within the base-block 7, andthe screwshaft 10 and nut 12 are mounted in the baseblock 7 within a chamber communicating with the chamber in which are mounted the visejaws Sand 11. The nut 12 projects upwardly and engages the outer end of the vise-jaw 11, as shown in Fig. 1. The 4screw-shaft 10 is smooth lbetween the bracket 13 and the end of the base-block 7, andthe end thereof is squared, as at 18 in Fig. 2. Ablock 19 is bored and revolubly mounted upon the screwshaft 10 between the bracket 13 and the end of the base-block 7, the plate 15 being cut away to receive it. l

The screw-shaft 10 bears a flange-piece 20, having a collar 21 integral therewith, and the ilange 2O is bored to it the screw-shaft l0 between the bracket 13 and the base-block 7, and thecollar 2l also fits said screw-shaft 10 and is keyed thereto, asiat 22 in Fig. 1.

The flange-piece 20. is provided with the usual number of perforations 23, circularly arranged therein and bored smooth, whereas in theordinary machine the perforations 23 are threaded. The block A19 is provided with. a deeply-cou'utersunk perforation 2li,

This base-block ICO 24 to receive the head of a set-screw.

`end against the head 26 of the pin 25.

(shown in Fig. 3,) the ordinary machine being provided with a block which is only slightly counter-sunk in the corresponding perforation A pin 25 is inserted in the perforation-24, and the head 26 thereot` rests in said countersunk portion, the shank thereof extending normally through the block 19 and into the perforallion 23.

A supplement-al catch pin 27 is screwthreaded at one end and screwed into the head 26 of the pin 25, which head is bored and threaded correspondingly. The catchpin 27 is bent at right angles outside of the bore 24 and'flattened at the outer end 2S, which end may, if desired, be milled.

A coil-spring 29 surrounds the catch-pin 27, within the perforation 24, and bears at one A plate 30 is secured upon the face of the block 19, adjacent to the outer end of the catch-pin 27, and is perforated to fit the bore of the collar 21 and the pin 34 and also squarely perforated to allow of the exit of the catch-pin' 27, which is formed square in cross-section to fit said perforation and cannot turn so as to be unscrewed from the head 26. Against the plate 30 bears the outer end of the coil-spring 29, and it is evident that to withdraw-the pin 25 from one of the holes 23 it is only necessary to grasp the catch-pin 27 by the head 28 thereof and pull ,it outward, drawing with itV the pin 25 longitudinally of the perforation 24 in the block 19.

The square end 18 of the screw-shaft 1() (shown in Fig. 3) is usually turned by means of a wrench when revolvingr the screw-shaft 10 to adjust the adjusting-nut 12; but I provide it with a crank or handle 31, which is keyed or pinned thereto, and it is evidentthat When the pin 25 is withdrawn from the perforation-23 in the flange-piece 2O said iiangepiece and said screw-shaft 1() may be revolved independently of the block 19.

An arm 32 is pivotally connected With the block 19, as at 33, by an enlarged end thereof,

a pin 34 passing 'therethrough and vthrough the perforations 35 in the block 19 and communicating with a recess 3b' thereof, in which said end 33 of said arm 32 is fitted. A pin 37 passes through the pin 34 to hold it in place. The arm 32 is pivoted to a rod 38, as at 39, and the arm 38 is so operatively connected with the machine as to be intermittently depressed to depress the arm 32 and rotate the block 19, the flange-piece 20, and the screwshaft 10 to adjust theadjusting-nut 12, and these revolutions describedof the screw-shaft 10 by means of the arm .32 occur at predetermined intervals, andra coil-spring 40, secured to the plate 15 at one en l,as at 41, and to the arm 32 at the other end, as at 42, -raises the arm 32 and the arm 38 and reversely revolves the block 19,the flange-piece 20,and the screwshaft 10 and reversely adjusts the adjustingnut 12. The purpose of the above-described intermittent adjustments of the nut 12 is to press the vise-jaw 11 firmly against the typeblanks between it and the vise-jaw 8 during ,molding of the type for the press from the molten metal in the type-n1 etal pot, as is fully understood by those skilled in the art of linotyping, and is no'part whatever of our invention.

The operation of our device will be readily understood from the foregoing description when taken in connection With'the accompanying drawings andthe following statement thereof.

`Having predetermined the desired position 'on the screw-shaft 10 of the vise-jaw 11, and

consequently of the adjusting-nut 12, the head 2801' the catch-pin 27 is grasped and the pin 25 is Withdrawn from whichever of the perforations 23 in the flange-piece 20 into which it may project. This movement unlocks the flange-piece 2O from the block 19, which is secured to the arm 32. The screw-shaf t 10 being keyed to the collar 21 of the Hange-piece 20,said fiange-piece and shaft are free to revolve independent of the block 19. The crank 31 is then revolved, revolving the screw-shaft 10 requisitely to advance or withdraw the adjustingnut 12 to such an extent or for as many ems as desired. The perforations 23 in the flangepiece 20 are arranged circularly at such intervals as shall allowof one of the same registering with the perforation 24 when the shaft 10 is revolved to the desired extent. The pin 25 is then allowed to enter the perforation 23 registering with the lperforation 24, being pressed therein by the spring 29. When the adj usting-nut 12 is in the proper adjusted position on the screw-shaft 10, the vise-jaw 1l is moved slidablyinto Contact therewith, and the mechanism operates as usual, employing the customary function of the vise-jaws 8 and 11.

The changes which it is necessary to make in the linotype-machine as now constructed to embrace our improvements are four in number: The perforations 23 inthe angepiece 2O must be smooth. The perforation 24 in the block 19 must be countersunk through nearly the entire thickness of the block 19. The bracket 13 or the end of the base-block 7 must be tiled to make room between them for the plate 30, secured to the block 19. The square end lSof the screw-shaft 10 must be provided with a pin or key for the crank 3l.

IOO

It is evident that with the above-enumerated set-screwliable to displacement by vibration and requiring considerable waste of time to manipulate, and the crank 31 takes the place of a wrench, liableto misplacement.

Having fully described our invention, We claim as new and desire to secure by Letters Patentf In a linotype-machine, a vise for holding the type-blanks while molding the type, said vise being provided With a screw-shaft and a slidably-adjustable member mounted above an angular portion and head, said block being provided on the outer surface thereof with a plate provided with a perforation through which said catch-pin passes, and a coil-spring mounted in said perforation in said block-and bearing against said pin and said outer plate, substantially as shown and described.

In testimony that we claim the foregoing as our invention We have signed ourvnames, in

presence of the subscribing witnesses, this 27th day of December, 1898.
