Figure 1 is a-sectional elevation of sufficient of a shaving apparatus to show the Be it known that I, BENJAMIN Josnrn JOHN GoULoINo, a subject of the King of the United Kingdom of Great Britain and Ireland, residing at 188 Fleet street,-in the Shzing Curved Stereotype-Plates, of which the following-is a specification.

In automatic machines such "as the autoplate and the auto-shaver, the knife is always revolving, and the closeness to the shaving arch, of the fixed adjacent parts, as well as the transit through the machine, of the procession of stereotype plates,makes it practically impossible to get at the knife. Now, it is necessary to get at the knife'for the purpose of adjusting it radially, and the this radial adjustment is necessary, are as follows: If all stereotype plates were letter press plates throughout, they would obviously require trimming to one standard thickness, and no radial adjustment of the knife, once set, would be required. But, at the present day, all stereotype plates are not letter press throughout, for many of them are partly letter press and partly processblock. Now, the surface of a process block must, to secure a good impression, stand a little higher than must the surface of the letter press. as a stereotype plate stands with its printing face to the shaving arch and its oppoto the knife, it follows that the high parts of. this printing face will be the base from which itsradial thickness will be measured for the purpose of shaving. Let it be assumed that theprojecend elevation as seen from'the left-hand end of Fig. 1; Figs. 3and 4 are sections taken respectively on the -lines 8- -'3 and kof Fig. 1, Fig. ,4: showing an alternative form of knife-controlling spring; Figs. 5 and 6 are o end elevations: showing the knife-adjusting means in positions respectively corresponding with the knife projected; and knife.retracted,1and Figs. 7 and S are ele 'vations, taken from positions at right angles to each other, showing devices'for manually adjustingthe'knife- 3 A designates the arch or plate holder in which the curved plate, which is to be shaved or trued out 1 on its inner side, is clamped and held; I

According to this invention, the knife '1 is held to the knifearmQ in such a manner as to leave it (the'knife) free to be adjusted radially or approximately radially inward and outward relatively to the axis of rotation of the said knife arm. For this pur-. pose the knife 1 is secured to the knife arm Qby. means of a keeper plate3 and a series of shouldered screws a, the latter of which pass through and'nicel fit holes in the keeper plate 3, and also through slots '5 inthe knife 1 (see particularly Fig. 4) which slots admit of the knife being moved independently of thescrews 4. Between press is three thousandths of an inch, which the headsof the screws 4 and the proximate it generally is, then for a stereotype plate that has any or all process block work in it, the knife must be retracted for the three tho-usandths of an'inch, in order that the process surface may be left three thousandths of an inch higher than the letter press surface. i I

The object of the presentinvention isto providemeans whereby the knife may be readily adjusted for trimming the two above-named kinds of plates no matter whether the plates reach the shaving apparatus in. batches of one kind, orthe other, or whether plates of the said two kinds are provided, these being adapted to hold the knifefirmly between the plate 3 and knife arm 2 while, at the same time, allowing'it to be moved radially, as later described. On the back of the knife 1 there is secured a rib 7 (see particularly Fig. 3) engaging with a slidingfit'in a groove 8 in the prox imate face of the knife arm 2, this rib and groove serving to guide the knife in its radial movement; j V i The 'under or non-cutting edge of the or inclined surfaces Patented Sept, s, 1914,

o the" apparatus in alternation,

face of the keeper plate 3, springs 6 are present improvementstherein; Fig. 2 isan knife 1 is formed 'with'two or more wedge 9, (three are shown in the drawings, see Fig. 1) with each'of which there engages a correspondingly inclined surface 10 formed on a longitudinally adjustable wedge bar 11 which is supported and free to slide on blocks 12 adjustably secured, as by bolts 13 and set screws 14,

screw 15 free to turn in a relatively fixed nut or hearing 16 fast to the knife arm 2, the outer end of the said screw having fasttoit .a tumbler 17, 17 adapted'to be turned in opposite directions, to two terfast to the knife arm 2.

In the space between the inner ends of the two blocks 12 there is located whose respectively opposite ends are attached or integral with,

10 of the wedge bar 11.

By the foregoing arrangement it will be seen that when the screw 15 and wedge bar 1 occupy their respective left-most positions in which they are shown in Fig. 1, the knife 1 will be at the minimum distance from its axis of rotation, being held in that position by the springs 23, and when they occupy their other respective terminal positions (the right-most as viewed in Fig.1) the knife 1 will be at the maximum distance from the said axis of rotation. The tumbler 17, 1'? is in pivotal connection with one end of a toggle link or rod 26 whose other end is free to slide in a guide 27 capable of oscillating about its axis in an arm 28 fast to the mife arm 2, the said axis of oscillation being so situated relatively to the axis of the screw 15, that when the tumbler is in taining both of the said axes.

its respectively opposite terminal positions, the link 26 will beat respectively opposite sides of an imaginary inclined plane con- The link 26 1s encircled by a compression spring 29 which serves to hold the tumbler in each of its two terminal positions, until it is p tively moved from that position to the other one, as hereinafter described.

When the shaving apparatus'is supplied from two casting plants, one turning out let ter press plates and the other turning out by a link 34 a spring 19- secured the -vertiplates having some process surface in them, means are provided by which theoperator can make the said apparatus adjust the radial position of the knife 1 according to the plate next to be shaved. These means are as follows: There is fast to the screw 15, the before-mentioned tumbler 17, 17 and, pivoted at 30 upon the machine frame, (see particularly Fig. 2), there is a bell-crank lever 31, 32, the arm 31 of which carries a pin or abutment device 33 adapted to be engaged by the tumbler'17, 17. The other arm 32 of the bell-crank lever is connected to a hand lever 35 40, the hand lever 35 being capable of being locked to the quad- 41 is engaged with the notch 38, as indicated in Fig. 2, the pin 33 is held clear of the path of the tumbler 17, 17, no matter in which of its two positions the time; when the bolt 41 is en aged with the notch 39, the in 33 is 1n in which it is marl r ed 33 in Fig. 2, so that at the next ensuing rotation ofthe knife arm 2, the said pin will notches 38, 39 and 40. When the bolt arm 17 of the tumbler (which latter would then be in which it is shown in Figs. 2 and 5) engagement the said tumbler from the last-named position to the knifeprotruding position, in which it is stopped by the pin 18, and the wedge bar 11 will consequently be moved so as to efiect the said protrusion of the knife. When the bolt 41 isengaged with the notch 40 and the pin 3 is consequently held in the position in by this will be turned which it is marked 33 in Fig. 2, the said I pin will be engaged by the tumbler arm 17 so that the said tumbler will be turned to the knife-retracting position, and the wedge bar 11, through the spring 19 will be correspondingly moved to allow the knife 1 to be retracted by its springs 23.

In applying this invention to a hand shaving box, the tumber 17 17 and all the parts marked. 18, 18 and 26 to 42 both inclusive, are, as shown in Figs. 7 and 8, replaced by a hand wheel 43 either duly scaled as at 44 to cooperate with a fixed index 45, or indented to cooperate with a its equivalent.

Among the modifications of which the before described apparatus is susceptible, there may be mentioned the employment of helical springs 46, see Fig. 4, instead of the coiled springs 23 shown in Figs. 1, 2, 3 and 8, for drawing the knife 1, inward, these helical springs (of which there may be any desired number) being attached at one end, to the knife arm 2, and at the other end,

pins 47 fast to the knife, and projecting the keeper plate necessity for 22 is removed.

been herein referred to inward, if, however, 33 be regarded as the knife-retracting and knife-projecting positions respectively then,

the screw 15 would have a righthand thread; it will be readily seen that this question of direction of thread has no connection with the hand-rotated screw shown in Figs. 7 and 8.
