sent the slug trimming mechanism, which it Animation nee reuruny to, mo. semi no. seam?.

T all who/in it'mo conm Beit known hat I, RT'HUR LE Boum', a citizen of the United States, residin at Woonsocket, `in Ithe count of i e Providence and State of Rhode Island, ave

invented a certain neiivv and useful Improvement in Adjustable Trimming Mechanism, of which the following is fa full, clear, and exact desci'iptionll0 .f This invention is especi' adapted tobe it part of a ma his@ of the linbty'pe dass, for ytheffmrpos'e of tirhminl the type bars or .Jslgs formed in such mac ines, in order that lthe;r may be of the required thickness.

.The particular object of this invention is to provide slu trimming mechanism which may be quick y and accurately adjusted to trim slugs of Adifferent thicknesses corre- .;sponding with 'the various sizes of type. 20 This mechanism necessarily includes two .knives,and means for moving one `or both lof said knives so as to change their rela tio, a movable stop carrier having a plural- -ity of stops which may be brought to oper- 255ative osition by the movement of the carrier, evices, intermediate of the movable knife and carrier, adapted to be moved when `the knife moves and to be carried against thel stops so as to positively limit the move- '30., ment of said knife.

',The embodiment of the invention shown includes other cooperating mechanical parts, .,.and' invention includes said parts tothe :extent set forth `in the appended claims.

These stop rods at their lower ends en age with, what is for the time being a rigi part of the knife block B', and at thelr upper ends they are so placed that they will engage with one or another of the cuter series of adjustable stops e'. Similar stop rods G ass through vertical holes in the same brac :ets a. and engage at their lower ends with what is for the time being a? rigid part of the upper knife block B; and the upper ends of said rods are in such position that they may engage the lower faces of one or another of the adjustable sto s e of the inner series.

As Wi l be seen from Fig. 5, and as will be understood from the foregoing description the stops e and e' are arranged in pairs, an each pair is associated with another pair diametrically opposed in position. Each set of four-that is tosay, two associated airsV of these adjustable stops, are re uire for the adjustment of the two knife locks for any given size or Vrather thickness of slug to be trimme Preferably there will be graduation marks on the top face of the carrier disk, as for linstance, 5, 6, 7, etc., to indicate that thev knives will, by the action of the indicated stops, be setto trim slu sto be 5 points, 6 points, ete., in thickness. n order to set the knives to trim the slugs to any reuired thickness, the lever F is unlocked v 4an swung to the right, as shown in Fig, 1. This will cause both knives to move down.

' Then the sto VL.carrier is turned to bring the proper set o :stops over the stop rods. An lindex plunger K in one of the rame members a isadapted to 'enterholes of which there are a number in the lower face of the fiegrrier E, when the latter has been moved ,uation marks.` Then the lever is swung overto the left. This will move either bar D o rjfD orboth. 'Let us assume that it moves bar D to the left, and that the bar D' for' example, it may encounter orrfthe timeJheingl Under such circumstances. the pivotal connection between lever` Frmdf helen@ bar D will. b; stationary, il :will ser?. 5a-a ffillcrum. boutwhich the lli-leyerfturnsf -."h1s mov,ement will cause the upper knife block 7B tofnioveupward carrysir :lOlsG with itantl they, by

mentwith two stopsfacheck its move' the engagement of the' essaie blocks, it will be seen, are positively stopped in positions which are determined by the positions of the lower faces or ends of the stops c, e. When the parts are in this position, the screw H is tightened so as to lock the lever F to the link C, and'thercby the knife blocks are held in the position stated.

In order that there shall be no springing of the disk E, it is provided along lts lower face with an outwardl extended flange e", and this flan e passes beneath overhan ing li s a' forme on the upper ends of the ars a ,-these over-hanging llps being so laced that they are as close as possible to t e ad- 'ustable stops e, e which are for the time eing in use to locatethe position of the knife blocks.

It is desirable that when the stop screws e and e have been once adjusted into noper position, they shall not be changed. evertheless, when the knives are sharpened, some of the stock on the cutting edges will bc ground off, and in that event; said stops would not serve their urpose, unless some means were provided or compensating for the grinding away of the knives. In order to provide such compensating adjustments, two screws M are screwed vertically into the knife block B near the ends thereof, so that the heads of these"'screws will be directly beneath the stop rods G. By turning these screws the throw of the upper knife block may be adjusted with accuracy, when such adjustment is necessary, without changing ,the position of the stop screw e. inasmuch' as it is not convenient, in the construction shown, to put a wrench head on the screws M, such head is put on the upper end of the stop rod G, and the lower end .of said rod is provided with a thin rib g which enters a slot m in the upper end of the corres onding screw M. Therefore, by turning either stop rod G, the correspondin screw M may be' Aturned in or out of tie knife block B.

Screws N are likewise screwed vertically into theknife block B so as to be directly beneath the stop rods G.

The described construction is such that both knife blocks are moved whenever the relative positions of the knife blocks are to be vadjusted for trimming-different sizes of slugs. There are, however, uses to which the described invention may be put, which requires only that oneknife block shall be moved to' adjust thedistance between the knives to suit the various sizes.

The described mechanism may be modified in various ways so that only one knife block will move. Perhaps a simple way to accomplish this result is to have a pin L, whlch can .be passed through one of the frame members af and the b'ar D'. This 4will prevent the movement of that bar and consequently of the knife block B' associated with it, but will permit the movement seems of the bar D and the associated knife block B. If this were done, or if in any way the lower knife block B' were rendered immovable a-nd the upper knife block were alone allowed to move, a readjustment of the stop screws e would probably be required. It is not likely that any one would ever go to the expense of putting in a movable knife block B and mecha nism for controlling its movement, and then provide mechanism for stopping such movement. The reasonable construction, when it is desired to move only one knife block, would be to permanently fix the other, and therefore to provide no mechanism for moving it. The construction referred to is shown, however, merely to indicate that the remaining parts of the mechanism are adaptedfor use to control the movements ofa single movable knife block. Where the knife blocks have been adjusted andlocked by the described mechanism, the type bars to be trimmed are forced between them in the direction of the arrow on Fig. 3. It will be seen from this figure that a slot a9 is cut through the plate A to permit the type bar to ass through it.

It is clear that t e invention as defined y by the claims is not limited to the specific embodiment thereof shown. Many changes from such specific embodiment may be madl` without de arture from the invention.
