DISTRIBUTING MECHANISM FOR TYPE-CASTING MACHINES.

Application filed April 29. 1912.

To all whom it may concern:

Be it known that we, PERCY WALTER Dnurr'r and VV1LLI M ROBERT GILPIN, both subjects of the King of Great Britain, residing in London, England, and whose post office address is 4:4 and 46 Leadenhall street, in the city of London, England, engineers, have jointly invented certain new and useful Improvements in Distributing Mechanism for Type-Casting Machines, of which the following is a specification.

This invention relates to the distributing mechanism of machines for casting type of the class which are provided with two or more magazines to accommodate a larger assortment of matrices which may be of one or of more than one font or variety.

In such machines the matrices, after the completion of the casting operation, are presented in the usual manner by the elevator to a single lift box and are conveyed along a single distributer bar by screws, the whole of this mechanism being of a kind common to single magazine machines. Below the single distributer are disposed the magazines, generally two, and mechanism is provided for separating the matrices after they leave the distributer bar and directing them into their respective magazines.

According to the present invention, the deflection of the matrices of different groups into their respective magazines is effected by means of a deflecting device, brought into operation by means external to the matrices, which is oscillated by mechanical means periodically operative with due regard to the progression of the matrices along the distributer bar. This deflecting device consists of two bars which are simultaneously oscillated outwardly from a central position so that one or other engages each matrix as it comes into position in such manner that it is deflected positively toward one side or the other. Which ofthe bars acts as the positive deflector is determined by the distinctive configuration given to the different groups of matrices, the most convenient method of effecting this selective action being to form the matrices with asymmetrical notches on their bottom edges right-handed notches for one group -or groups and left handed for another group or groups. No claim however is herein Specification of Letters Patent.

made for such configuration of the matrices or broadly for utilizing such distinctive configuration for effecting their division or distribution into groups.

The means whereby this is effected are hereinafter described with reference to the accompanying drawings, wherein Figure 1 is a transverse section of the matrix distributing mechanism taken on line I-I of Fig. 2 which is a front elevation of the same; Fig. 1 is a section corresponding with part of Fig. 1 but showing the matrix and deflectors in another position; Fig. 3 is an elevation; Fig. 4 a part rear elevation; and Fig. 5 is a transverse section show ing mechanism.

On leaving the distributer bar a the matrices b are guided to fall substantially vertically on an arresting device which consists preferably of two bars 0 0 running longitudinally the full length of the distributer bar a and magazines (Z, cl.

Usually and preferably the abutment upon which the matrices fall on leaving the distributer bar is constituted by the two bars the lugs of which serve to deflect the matrices to right or left, the two parts of the foot of each matrix on the respective sides of the notch resting upon the surfaces of the respective bars. WVith an arrester of this form each bar is provided with a lug or projection 0 designed to effect the deflection of the matrix 6 to its appropriate magazine (5 or cl, as will be described later on; in any case, whether an arrester separate from this deflecting device is used or not, these deflecting bars are provided with lugs as above described.

The deflector bars 0, c are pivotally supported at their ends and may be further supported at intervals along their length, a periodic intermittent oscillatory movement being imparted to the bars by means of a cam 6 operating any suitable linkage (such as a rack f engaging a pinion 0 mounted on the axis of one deflector and meshing with another pinion c on the axis of the other deflector) in such a way as to impart positive movement in one direction to the deflectors which are spring-urged in the return direction, as for example by means of the spring f which urges the rack so as to keep the roller f bearing against the cam 6.

The matrices have on their bottom edges notches having a steep side b and a sloping side 6 similar to a ratchet tooth, these notches being arranged right-handed or left handed, according to which of the two magazines it is desired to deflect the matrix to. The matrices are also provided with the usual permutations of selecting teeth I)", those matrices belongingto corresponding channels of the two magazines having the same configuration of selecting teeth, but differing inrespect to the notches on their bottom edges.

The vibratory movement of the deflectors a, 0, being effected by means of a cam on a shaft driven from one of the distributer spindles, is so correlated withthe advancing movement of the conveyer screws 9 of the distributenthat at the moment the matrices reach the abutment by which they are arrested in their downward fall, 0. g. by the deflector bars 0, the lugs 0 of the deflectors are closed against each other, thereby permitting the notches on the bottom edges of the matrices to straddle the two .lugs of the deflectors.

To insure the matrices falling properly so as to straddle the lugs c, c and prevent their premature deflection oscillating guide plates 71,72. are provided extending the length of the distributer and slotted to accommodate the edges of thedivision plates 2' of the magazine. The axles or pivots h 71, of these guide plates are parallel with the defiector bars and are oscillated mechanically in timed relation with the movement of the deflectors so that the plates begin to lift from the position shown in Fig. 1 toward the position shown in Fig. 1 just prior to the opening movement of the deflector bars 0, 0.

As shown in the drawings, the oscillation of the plates h, 72, is effected-by means of a cam j which is driven synchronously with the cam e by suitable connecting gears and which actuate-through roller j a bell crank lever j pivoted at j andconnected at its outer end with a pair of adjustable toggle links j which in turn are connected with cranks h, h on the axles of the respective guide plates h, h. Theguide plates h, h are spring returned to their normal position (Fig. 1), as by means of the springs h 72, on the axles of the plates.

Upon the deflector bars being thrown out- .ward or opened, the lug c of one bar or the other engages the driving face I) of the notch in the foot of the matrix resting on the bars and impels the latter to the right or left according to the disposition of the notch, the lug on the other deflector'bar engagingithe sloping side 6 of the notch so as to give an initial itilt to thematrixtoward the opposite side. After the matrix is thus thrown to one side or the other, an abutment (one for each side or magazine) suitably disposed in its path serves to erect it, so that it may fall suiiiciently uprightly into the channel (Z leading to its appropriate magazine.

Sometimes it may be necessary to use matrices from only one magazine and in such a case it is an advantage to save wear and tear of mechanism by rendering the deflecting mechanism inoperative. Under such circumstances a pivoted guide plate or comb m provided for the purpose is brought into operation manually 3y being swung into an appropriate position (shown in dotted lines in Fig. 1) so as to guide all the matrices leaving the distributer bar into one magazine only. The linkage whereby this guide plateor comb is moved into the operative position is preferably arranged also to effect the opening of the deflecting bars, thereby bringing the respective rollers which operate the linkage of these mechanisms clear of their actuating cams and thus stopping all movement of these parts.

As shown in the drawings, the oscillation of the comb m, which is arranged to ut off the lower magazine, is effected by means of a cam groove a on a disk a mounted on a stub shaft which can be rocked by the operator while sitting at the key board of the machine by means of suitable mechanism, indicated at n or other suitable transmission device. The cam n actuates a crank m on the pivot axle m of the frame of the comb m which is returned to the normal position, shown in full lines in Fig. 1, by means of a spring a applied to the axle of the cam disk 12.

The actuation of the guide plates 71-, h as well as the deflector bars 0, c is effected to render'the same inoperative by means of a second cam groove n on the disk at which through a bell crank lever 0, link 0 and bell crank lever 0 operates to displace a crank arm h on one of the pivot axles h" of the guide plates in such a direction that the guide plates are thereby raised to the position shown in Fig. 1 Simultaneously, the same bell crank 0, operating through a link 0 preferably made adjustable, actuates a lever f which engages a stop f on the rack f and retracts the latter against the pull of the spring 7, thereby throwing the deflector bars outward as shown in Fig. 1.

Vided for stopping the'machine when the inatricesifail to drop clear of the screws and are thus driven against a division plate. The controlling member of this mechanism is a rack bar, indicated at 9 (Fig. 2), which engages the edges of the springy top parts of the division plates, and is displaced longitudinally under the circumstances above indicated and thereby actuates mechanism so as to stop the machine. This controlling element of a known cut out device is utilized in the present invention to stop the machine should the guide plates h, it fail to return to their normal position. A roller r on one arm of a three-armed lever r fulcrumed at r engages a cam which revolves synchronously with the cam j. The effective part of this cam is a depression r which comes under the roller r" when the cam j is in the position corresponding with normal position of the plates it. Should these plates be in their proper position the roller r is prevented dropping into the depression r by means of a stop It on the crank it engaging an adjustable pin r on an arm r of the lever r and nothing further happens. Should, however, the plates/t and consequently the stop if not be in their normal position when the depression 1 comes under the roller 1", the lever r is shifted by means of a. spring r and the third arm r of the lever T, which normally forms an abutment or latch for a spring-urged crank lever s, is withdrawn so as to release this lever s which is then impelled by its spring a and operates to shift longitudinally the rack bar 9 with which it is connected, thereby bringing the cut out mechanism into play and stopping the machine. Since this cut out mechanism would otherwise always be operative when the cut ofi comb m is in use and the plates 72, are consequently permanently in their raised position, it is arranged that the lever 1' should be prevented from moving into the cut out position as soon as the cam disk it begins to actuate the bell crank lever 0, by causing the end 0 of one arm of the lever 0 to engage another arm 9 of the lever 0 the cooperating surface of this arm being struck to a circle having its center at the pivot axis of the lever 0. p

A modified construction of deflecting apparatus is shown in Fig. 6 which is a part transverse section corresponding with the view shown in Fig. 1. As herein shown the arresting and deflecting bars 0, 0 with their lugs a, c, are made integral with the steadying plates or guides 72, and consequently the separate mechanism for actuating the deflector bars 0, c synchronously with the guide plates 71, is dispensed with. In the construction shown, the deflector bars are constituted by inwardly projecting ledges c, '0, along the lower edges of the steadying plates it, it these ledges having upwardly projecting beads or lugs c, 0, along their inner edges which eeoperate with a notch or notches b, b in the lower edge of the matrix Z), substantially in the manner described with reference to the other figures of the drawings.

'As shown in the drawing two notches b, b are formed in the lower edge of the matrix one of which, I), has square or steep shoulders or sides, while the other 6 has a square or steep inner side and a sloping outer side. Alternatively the two notches may be combined in a single notch, as shown in Fig. 1, having a steep side Z), and a sloping side 5 v I Having thus described the nature of the said invention and the best means we know of carrying the same into practical effect, we claim 1.
