Specification of Letters Patent.

Patented Apr. 8, 1913.

. Application filed September 21, 1910. Serial No. 583,051.

particularly to the means whereby the knives used for trimming the resultant cast lines, are adjusted for different body dimensions through the intermediary of the wheel carriage upon which are mounted the line-casting molds.

The said invention is an improvement or modification of that for which a patent was granted under No. 941,884 on November 30th 1909. According to that patent the apparatus was so constructed that the mold wheel or carrier effected the movement of the adjustable knife in only one direction, while a spring or springs moved it in the opposite direction; the object of the present invention is to so construct the said apparatus that the mold wheel or carrier shall effect or control the adjustment of the movable knife both toward and away from the companion or relatively fixed knife.

The invention will be best understood by reference to the accompanying drawings in which, as an example, it is shown applied to appropriate parts of the; machine known commercially under the trademark Linotype.

In these drawings Figure 1 is a right-hand side elevation showing the knife-block, and, in vertical section, a portion of the mold carrier; Fig. 2 is a rear elevation of the trimming knives and knife-block; Fig. 3 is a horizontal section taken about on the line 33 of Fig. 1, and with certain parts omitted; Fig. 4 is a front elevation of the mold carrier, with two molds thereon of respectively difierent body dimensions; Fig. 5 is a view corresponding to Fig. 1, of a modified construction of the devices shown in that figure; Fig. 6 isa rear elevation of the adjustable knife and other adjacent parts, and Fig. 7 is a plan, partly in section, and Fig. 8 an elevation of detached parts of the apparatus shown in Figs. 5 and 6.

1 represents the fixed knife-secured, as

ordinarily to the vise frame or other relatively stationary part 2 (Fig. 3) of the machine frame; 3 represents the adjustable knife, horizontally guided on the knife block 4 in well-known manner so that it can be moved toward and away from the companion knife 1, and only thus. The knifeblock 4 as ordinarily is detachably secured to the part 2.

5 is a spring (there are preferably two such springs) constantly tending to move the adjustable knife 3 farther away from the fixed knife 1.

6 is the mold carrier which, as illustrated, takes the form of the well-known mold wheel; 7 and 8 are two molds secured to the mold carrier 6, of respectively difierent body dimension.

All of the foregoing parts are common to .both of the constructions illustrated in the drawings.

With particular reference to the arrangement represented in Figs. 1, 2 and 3, 9 is a double stepped wedge having at each end, two surfaces 10, 11 situated in two different parallel vertical planes, the said surfaces being connected by an inclined or curved surface 12, and the distance apart of the two said planes corresponding with the difference in the body dimensions of the two molds 7, 8. The surfaces 10, 11 are adapted to co-act with abutment screws 13 adjustable in the lugs 14 integral with the knife block 4.

15 is a pin fast to the wedge 9 and projecting from .the right-hand side thereof, 16 is a three-armed lever pivoted on a stud 17 fast to the knife block, and the middle arm of which, by its forked end, engages with the pin 15. The upper and lower arms of the lever 16 are each pivoted to a cranked rod 18 or 19 which, by a screw and slot 20, is guided on the side of the knife block 4. The rear ends of the rods 18 19 extend into the forward path ofthe mold carrier, and adjacent to the two molds 7 and 8 there are provided two recesses or holes 21, 22 adapted to freely receive the rearward ends of the rods 18, 19 respectively. The mold carrier 6 is also provided with the usual registering sockets or pins 23; these, however, constitute no part of the present invention.

By the foregoing arrangement the wedge 9 must occupy its lower position when the mold 8 of the smaller body dimension is in use, and its higher position when the mold 7 of the larger body dimension is in use, and for this purpose the mold carrier 6 is adapted to correspondingly operate the two rods 18, 19. Thus, when the mold 7 is in use, the advance of the mold carrier 6 presents a solid part of the latter to the rod 18, and receives the rear end of the rod 19 in the hole 22, and in the reverse manner, when the mold Sis in use, the advance of the mold carrier 6 presents a solid part of the end of the rod 18 in the hole 21. Consequently, if the advancing mold carrier 6 finds either of the rods 18 or 19 projecting into its forward path at a part at which it is unprovided with a hole 21 or 22, that red will be moved forward and the wedge 9 will be correspondingly raised or lowered.

hen for the two molds 7 and 8- represented in Fig. 4, others are substituted, for larger or smaller body dimension, but be tween which dimensions there is the same relative difference as in the substituted molds, the screws 13 can be adjusted to provide for such altered conditions, without changing the wedge 9, but when the two substituting molds have not the same relative difierence of body dimension as the substituted molds, then a new wedge having the desired different step relationship, must be substituted for that last used inthe machine. The arrangement shown in Figs. 5 and 6 allows of the preliminary or manual knife adjustments for changes of body dimension being more readily effected than does that previously described, and without risk of disturbing the parallelism of the knives as is the case when the abutment screws 13 are turned. Inv this arrangement the wedge 9 is of the inclined type as distinguished from: the stepped type shown in Fig. 2, and it has, as already well known in the art, two inclined surfaces, one at each end; it is connected. with the three armed lever 16 in the same manner as that before described with reference to Fig. 1,.but the said lever, as distinguished' from that in. the preceding example, is resiliently connected to the rods 18,. 19. For this purpose each of the rods 18, 19' hasa forwardly extending arm terminating in a hook 2 1 to which is attached one end of a-spri-ng" 25 whose other end is attached to a pin 26 adjustably secured in the respective armof the lever 16. This pin 26- penetrates a slot 27 in the respective rod 18 or 19 and terminates in a head 28 between which: and a collar 29' the said rod is capable of sliding relatively to the pin 26 in the y direction of the length of the slot 27, and

only thus.

The rear ends of the'rods 18, 19 of Figs. 5 and 6,. are guided in lugs 30 integral with the knife block 4,. and on the back of the wedge 91 are: carriedtwo' vertical. adjustable abutment screws 31. adapted to co-act with 33 in the respective arm of the lever 16, and

it may, by a nut 31: or otherwise, be secured in different positions along the said slot according to whether the particular body dimensions to be provided for, require the latter to the rod 19 and recelves the rear wedge 9 to be moved in av higher or lower zone.

1n the operation of the last described device, the inward and outward movement of the knife 3 relatively to the companion knife 1 (which latter is not represented in Figs. 5 and 6) is arrested at the instant at which it is at the pre-determined distance from the said companion knife, by the respective screw 31 abutting against the corresponding lug 32, and if at that instant the mold carrier 6 had not yet reached its foremost position, it, by its further forward motion, moves the appropriate rod 18 or 19 still farther forward, this excess of motion of the rod, however, has no effect on the lever 16 and results merely in the elongation of the respective spring 25 which, on the retraction of the mold carrier 6, contracts to its original length.

For adjusting the last described devices to suit molds of other body dimensions than those indicated, the simplest method is to remove the wedge 9 then in the machine, together with its abutment screws 31, and substitute therefor another wedge with its abutment screws so adjusted as to permit of the said wedge being operated in a different zone from that appertaining to the substituted wedge. Or, the wedge may have its screws 31 adjusted without its position on the machine being disturbed.

In respects other than those just particularized, the operation of the devices shown in Figs. 5 and 6 is practically the same as that before described with reference to Figs. 1, 2, 3 and 1.

It will be observed that the only essential requirement in carrying my invention into effect is to have for each mold means to effect a positive actuation in both directions of the knife adjusting means, and while it is preferred to have the surfaces by which the adjusting devices are actuated on the mold carrier, it will of course be understood that these surfaces may be on the mold themselves or located elsewhere, as may be most convenient.

Having described my invention, what I claim and desire to secure by Letters Patent is z 1.
