VERNON BOYLE, OF PATERSON, NEW JERSEY.

REGISTERING AND SQUARING MACHINE.

Application filed April 3, 1919. Serial No. 287,265.

' 7 '0 all whom it may concern Be it known that I, VERNON RoYLn, a citizen of the United States, and resident of Paterson, in thecounty of Passaic and State of New Jersey, have invented a. new and useful Improvement in Registering and Squaring Machines, of which the following is a specification.

This invention relates to registering and squaring machines with the object in view ofproviding such a device which is sturdy and relatively simple in construction while adapted for accurate use in a wide field of operation.

Another object is to produce such an apparatus in which the work may be mounted in a single holder and manipulated in con-- nection with a squaring and lining device so as to enable the operator to rapidly and accurately determine the content to be re- ,tained in the work and to square the same with respect to the edge of the negative or plate, as the case may be.

Another object is to provide such a ma- 26 chine which is fitted with means for briljliantly illuminating the work (negative) from beneath, and also for intensifying the illumination at any desired portion of the work.

Another object consists in providing such an apparatus which contains improved. mechanism for accurately adjusting the work holder with respect to the squaring and lining mechanism.

Another object consists in providing such an apparatus which includes mechanism for temporarily limiting the movement of certain parts so as to facilitate repetition of the same operation without the necessity of repeated adjustment.

Another object consists in providing such an apparatus which includes improved means for holding the work.

Another object consists in providing such an apparatus which contains certain improvements in the form, construction and arrangement of the several parts, whereby the above named and other objects may-be e'f fectively attained.

The translucent table and lighting means herein shown and described, but not claimed, forms the subject matter of my co-pending aimlication Serial No. 571,398. filed June 28th, 1922.

The apparatus includes a base 1 which is provided with suitable lugs 2 for the reception of lag-screws or the like for securing the apparatus in position on a stand or other convenient support. A sturdy pillar 3 is centrally fixed on the top of the base 1 by cap screws 4, and is encompassed by a hollow leg 5 to the upper end of which is fixed, by means of screws 6, a bracket 7 (see Fig. 5).

On the bracket 7 there is secured by screws 8 (see Fig. 1) an open rectangular framework 9. The framework 9 is rabbeted for the reception ofa ground glass top 10 which is firmly held therein by a filling of cementitious material 11, such as plaster of Paris. The framework 9 and top 10 constitute the table for supporting the work, which may be a negative or a plate, and it will be understood that the glass top 10 is translucent.

Thetable 9. 10, is fitted with clamping mechanism for temporarily holding the work in position thereon. This clamping mechanism (see Figs. 4 and 5) consists of a pair of jaws 12, 13 which are rabbeted for the reception of the negative or plate that constitutes the work 14. Each of said jaws has a set of yielding plugs, 15, composed of rubber or the like, which are set into the rabbets and protrude slightly for engagement with the edge of the work. Thus the work may be firmly held without any danger of injury.

The jaw 12 is pivoted to the ends of a pair of swinging arms 16, 17 each of which has its other end fulcrumed by integral stems 18, 19, in bosses which project laterally from the table frame 9. The arm 16 is designed to operate idly on its fulcrum, while the arm 17 has a bell crank lever, including two branches 20; 21 fixed to the lower end of its stem or fulcrum 19. The branch 20 is connected by means of a retractile coil spring 22 with a pin 23 that is fixed in the frame 9, so that the inner end of the arm 17 is normally urged tothe right (see Fig. 4) so as to yieldingly force the jaw 12 inwardly toward the jaw 13. arm 17 imparts a similar movement to the arm 16 through the intermediation of the j aw 12. The jaw 13 is pivoted to the inner end of a swinging arm 24 the outer end of which is fulcrumed by anintegral stem 25 This movement of the in a boss formed on the side of the framework 9, while a bell crank having branches 26, 27 is fixed to the lower end of the'stem 25. A retractile coil spring 28 is secured to the end of the branch 26 and to a pin 29 set in the frame 9. Thus it will be seen that the arm 24 is mount-ed and normally actuated in a manner similar to the arm 17, with the result that the jaw 13 is normally urged toward the jaw 12 under the influence of the spring 28.

An eccentric 30, having an operating handle 31, is set in a bracket 32 that is secured to one side of the framework 9, and a pair of rods 33. 34 are pivoted at opposite sides of the eccentric 30, as indicated at 35 and 36. Each of these rods has its free end bored and adapted for the reception of male screws 37, 38 that are arranged for rotatable but fixed against sliding movement in sleeves 39, 40 which. are pivoted to the branches 21 and 27 of the bell cranks by screws 41, 42. The outer ends of the screws 37, 38 are fitted with milled heads 43. 44 for manually adjusting the same; and it will be noted that, by turning the said heads. the effective length of the rods 33, 34 may be altered so as to fix the normal position of the jaws 12. 13. From the foregoing description it will be observed that, by swinging the lever 31, the jaws 12 and 13 may be retracted from each other against the tension of the springs 22 and 28; while, when the lever 31 is re leased, the said springs will urge the said jaws toward each other until they come into contact with the work. A bolt 45 passes through the eccentric 30 and bracket 32, and has its upper end threaded for the reception of a tail nut 46 which may be actuated for clamping the eccentric 30 in any desired adjustment.

A lever 47 (see Figs. 3, 5 and 11) has one end embracing with a bearing fit the reduced lower end of the hollow leg 5, and the said end of the lever 47 is enlarged and developed into a pair of outwardly and downwardlv projecting feet 43 that are adapted to ride upon a curved track 49 which is fashioned upon the top of the base 1. The upper part of the lever 47 carries an arcuate rail 50 and a wheel 51 is fixed in the end of a laterall projecting stud 52 that is integral with the hollow leg 5, which said wheel is adapted to ride upon the rail 50 for supporting the leg 5 and hence the table 9, 10. The disposition of the track 50 and wheel 51 such that, when the latter is on the former. the leg 5 will be supported slightly above the lower flange of the pillar 3 so as to permit readyrotation of the leg on the pillar.

A pair of adjustable stops 53, are arranged on the inner end of the lever 47 adjacent each end of the arcuate rail 50: and the construction is such. that when the wheel 51-rol-ls 01f either end of the said rail it will drop slightly and bring the stud. 52 .into engagement with the adjacent stop 53. In such a position the wheel, and hence :the table 9, 10, will be temporarily held against movement in either direction with respect to the lever 47 until the wheel 51 is manually raised so as to again rest upon the rail 50. The length of the rail 50 is such that when the stud 52 has passed from engagement with one stop 53 to an abutment with the other, the leg 5, and hence the table 9, 10, has traversed an arc of exactly 90;

About midway of its length the lever 47 rests upon a curved rack 54 (see Figs. 5, and 11) which rack is toothed on its outer edge and graduated into degrees. The zero point is midway of the rack and the graduations extend for a distance of about 70 on either side thereof. The rack is secured to the base 1 by means of screws 55, and it is calculated that the lever 47 shall slide upon the upper surface of the rack during. the swinging movement of the lever to be hereinafter described.

Mechanism is provided for causing the lever to have engagement with the teeth on the rack 54 and for adjusting the said lever in either direction along the rack. This mechanism consists of a pinion 56 (see also Figs. 12, and 13) that is rotatably mounted, by means of a screw 57 in a rocking arm 58 which is pivoted by a screw 59 in the upper part of the lever 47. The rocking arm 58 has a grip 60 which is formed integrally therewith and protrudes outwardly adjacent the outer extremity of the lever 47. A retractile coil spring 61 has one end fast to the extremity of the rocking arm 58, adjacent the pinion 56 and the other end anchored to a pin 62 fixed in the side of the lever 47. The action of the parts just described is such that the pinion 56 is normally held in mesh with the teeth on the rack 54, while the operator may, by seizing the grip 60 together with the end of the lever 47 swing the arm 58 about its pivot 59 so as to withdraw the pinion from the rack. In this withdrawn position it will be obvious that the lever 47 may be manually swung to the right or left at will. This mechanism also comprises a device for rotating the pinion while in mesh with the rack so. as to finely adjust the lever 47 in either direction for the purpose of supplementing the less accurate movement of the lever when it is manually swung, as just described. This device is a shaft 63, which is journaled at 64a-nd 65 in the lever 47, andhas its inner end provided with a worm 63* which engages the pinion 56. A milled head 66, which is fixed to the outer end of the shaft 63, serves for the manual operation thereof; and it will be understood that the turning of the shaft 63 inithis manner will impart slow rotation to thepinion 56 and thereby move the lever 47 to the right or left as the case may be. A sight 67 is formed in the lever 47 so as to permit the reading of the graduations on the rack therethrough.

F rom. the foregoing description it will be clear that, when the table 9, 10 has been turned to either of its extreme positions with respect to the lever 47 so that the wheel 52 is resting against one of the stops 53, the movement of the lever 47 either by direct manual operation or through the actuation of the shaft 63, will swing the table 9, 10 to the right or left a corresponding distance. Furthermore, in whatever position the lever 47 may be, the table may be shifted to right or left a distance of 90 with respect to the lever, by the hand of the operator.

As before noted, the table top 10 is translucent and means is provided for thoroughly illuminating the work (negative) 14. This means comprises a. pair of electric lights 68 which are fast in reflectors 69 (see Figs. 9 and 10) that are secured to brackets 70, which latter are fixed at opposite sides of the frame 9 by screws 71. These reflectors 69 may be composed of suitable sheet metal such as polished aluminum, and it will be noted that the reflectors pass around the out side of the lights and project inwardly and downwardly beneath the lights so as to reflect the light upwardly. In order to more brilliantly reflect the light and to be able to intensify the illumination of the work at any desired portion thereof, I have provided a pair of reflecting mirrors 72, which are hinged on a common pintle 73 which is mounted in lugs 74 depending from the frame .9, as clearly shown in Figs. 5 and 10. Theserefiecting mirrors 72 project downwardly and outwardly so as to be complementary to the reflectors 69, and their angularity may be varied by adjusting rods 75. Each of these rods in rotatably mounted in but fixed against longitudinal movement in sleeves 76 which are pivoted at 77 in the sides of the frame 9. The extremities of the rods 75 are threaded into tapped sleeves'78, which are pivoted at 79 on the edges of the reflecting mirrors 72. Each mirror has one rod 75 connected to it and the said rods are located at opposite sides of the frame 9. Milled heads 80 are pinned to the upper ends of the rods 75 for manual operation thereof. It will be clear that, by changing the angularity of the mirrors 72, the angle of reflection will be changed so as to vary the intensity of illumination of different portions of thework. The wires (not shown) for the lights 68 may be led from a suitable source of current supply through an opening in the base 1, a tube 81, composed of insulating ma terial, located within the pillar 3, and thence through a pair of branch tubes 82. also composed of insulating material, and leader 82* to the lightsfiS. 1 I.

The squaring or lining mechanism will now be described. A pair of rulers 83 (see Fig. 1) are slidably mounted, asat 84:, upon a cross bar 85 which is journaled in bearings 86, 7 that are carried by stanchions 88, 89 (see also Fig. 1) mounted on the base 1.

The cross bar 85 is threaded, as shown at.

90 for engagement with a pinion 91 (see Fig. 3) which is carried by a spindle 92 mounted in the upper part of the stanchion 89. A hand wheel 93 is splined to the spindle 92 for manually operating the pinion 91; and it will be understood that the rotation of the said pinion will slide thebar 85 longitudinally in its bearings so as to move the rulers S3 in the same direction across the top of the table. The purpose of this provision is to enable the operator to bring the rulers into such a position that they will embrace-the desired portion of the subject matter on the work. A thumb screw 94: is threaded onto the upper end of the spindle 92 and may be manipulated to act as a lock-nut to preven accidental movement of the bar 85.

liflechanisin is also provided for simultaneously moving the rulers toward or away from each other; and this includes a pair of racks 95, one secured to each of the rulers 83. These racks mesh with a common gear 96 (see Figs. 7 and 8) that is keyed to a bolt 97 which is fitted in a bracket 98 secured to the bar 85 by means of set screws 99. A hand wheel 100 is keyed to the upper end of the bolt 97, so that the bolt may be rotated and hence actuate the gear 96 to move the racks 95 in opposite directions, in a well understood manner; this movement imparting corresponding movement to the rulers 83. The purpose of this arrangement is to enable the rulers to be set so as to include between them the desired amount of the work; or, in other words, to enable the marking of the work so that it may be out to the desired dimensions. A thumb screw 101, is threaded onto the upper end of the bolt 97 forlocking the parts against movement.

This ruler actuating mechanism includes a micrometer gage which consists of a plate 102 that issecured to the bracket 96 by pins 103. A disc 1041 has its periphery beveled and fitted in an angular recess tashioned in the top of the plate 102. as clearly shown in Fig. 7. The bevel of the disc 104 may he graduated into inches and tr-actions thereof, or into points and picas; may be dc sired. In the present instance it is shown as divided into twelve inches. with subdivisioi'is, as illustrated in Fig.6. The plate 102 has an upwardly extending sleeve 105 which surrounds the bolt 97. and the inner part of the disc 10% rests upon the flange of a sleeve 106 which surrounds the sleeve 105. The flange of the sleeve 106 extends between the plate 102 and the disc 10%. A pin 107 serves to lock the hand wheel 100 to the sleeve 106. A washer 108 rests upon the the sleeve 106 together. Hence, the rotation of the hand wheel 100 for the purpose of actuating the rulers 83, as just described,

will simultaneously rotate the disc 104 upon the plate 102, and thepassage of the graduations on the said disc by the Zero point, which is marked on the plate 102 (see Fig. 6), will present to the eye of the operator information asto the distance the rulers have been moved toward or away from each other. Consequently, the desired sep' aration of the rulers may be readily predetermined and effected. Means is also provided for temporarily limiting the rotary movement of the bolt 97, and hence the movement of the rulers 83 in either direction, so as to enable the latter to be repeatedly set at given points for determining the lining of, the work to establish its width and depth, without the necessity of observing and setting the micrometer disc. This means includes a pair of what I call limit steps, which consist of two collars 110,

1.11 that embrace thesleeve 106 and lie adjacent each other. These collars are split, as clearly shown in Fig. 6, and have enlarged portions contiguous the line of severance. One of the said enlarged portions on each of the collars is bored and interiorly threaded for the reception of threaded thumb, screws 112, 113 which have shoul-.

ders that bear against the outer part of the other enlarged portions. It will be understood that each of the collars 110 and 111- are the same with respect to the construction just described. As will be clear, the operation of the thumb screws will serve to tighten or loosen the collars so that they will firmly grip or rotate with respect to the sleeve 106. Each of the said collars has a tail 114i, 115 which projects radially and is adapted to contact with an upstanding post 116, which is set into the rear part of the plate 102. As a result of this construction it will be seen that. when the thumb screws 112, 113 are tightened, the engage ment of the tails 1141. 1.15 with the post 116 will terminate rotary'inovement ot' the bolt 97 and hence stop the movement of rulers 83. In operating this mechanism the hand wheel 100 may be turned until the rulers 81-3 have been set to the desired separation for determining the width of the work. At this juncture one of the collars 110. 111 is turned so as to bring its tail in contact with the post 116 and its thumb screw, 112 or 113 as the case may be, is tightened. The hand wheel. 100 is then turned in the opposite direction until the rulers have been set-the proper distance for lining the depth of the work, and the other of the collars 110, 11.1 is turned until its. tail contacts with the other side of the post 116. The thumb screw in the last named collar is then tightened. l/Vith the parts in this condition it is simply necessary forthe operator to turn the wheel 100 in one direction until tail of a collar abuts the post 116, at which time he will know that the rulers have been properly set for the width of the work. In the next operation it is merely necessary to turn the wheel 100 in the reverse direction until the tail of the other collar abuts the post, at which time the rulers will be properly set for the depth of the work. This contrivance thus enables rapidity in using the apparatus when it is desired to line or square a series of plates of the same size. When the collars 110, 111 are not being used their tails may be fixed against the post 116 by dropping the bent locking pin 117, which is carried by the tail 114, into the hole in the tail 115.

It has been mentioned above that the cross bar 85 may be slid longitudinally for causing the rulers to encompass the desired portion or content of the work. In this connection I have also provided stop mech anism for enabling the rulers to be repeatedly set at any desired point with respect to the work, without the necessity of examination. It will be understood that this refers to the simultaneous movement of the rulers in the same direction over the work and has nothing to do with the separation of the rulers from each other. This stop mechanism consists of a pair of stops 118, 119 (see Figs. 1, and 4) that are slidably mounted on a rod 120 and have set screws '121, 122 for temporarily fixing them in any desired position on said rod. The rod 120 has one end fixed in a crank handle 123, which is fast to an end of the bar 85; and the rod 120 traverses a bearing 124 which is formed in the end of an arm 125 (see Fig. 2). The arm 125 has a sleeve 126 that projects laterally within the journal 86 and has a circumferential groove fitted to receive the point of a screw 127 that is threaded in the top of the journal 86. The sleeve 126 has a free sliding and rotating fit with respect to the bar 85. This construction prevents the arm 125 from moving when longitudinal motion is imparted to the bar 85. In using this mechanism the operator actuates the hand wheel 93, as previously described, until the bar 85, and hence the rulers 83, have been moved to the proper position for containing the desired content of the work when the latter is held in position to be lined for its width. The stop 118 is then slid along the rod 120 until it abuts the bearing 124, in which position it is secured by the screw 121. The wheel 93 is then turned in the reverse direction so as to slide the rulers 83 into the proper position for bounding the desired content of the work when it is in position to be lined for depth. The other stop 119 is now slid along the rod 120 until it abuts the bearing 124, in which position it is fixed by the screw 122. Now it will be seen that, for resetting the rulers 83 with respect to the content of the work in subsequent operations involving the same subject, it is merely necessary to turn the wheel 93 until first one and then the other of the stops 118, 119 contact with the bearing 124.

In order to enable the rulers to be swung out of the Way when desired, the bar 85 has a second crank handle 128 fixed to the other end thereof, by which it may be manually turned so as to elevate the rulers into a vertical position. Suitable mechanism is provided for yieldingly retaining the rulers in either of the said positions; which mechanism consists of an angle arm having two parts, 129 and 130; the said arm being pivoted at 131 in the stanchion 88. The part 130 of the angle arm is connected by means of a retractile coil spring 132 with the j ournal 86, so that the part 129 is normally urged forwardly. This part 129 has a flatface which is calculated to contact with lugs 133, 134 and 135 that are carried by the arm 125. It will be noted that the said lugs form, collectively, abutments disposed at right angles to each other. When the bar 85 is turned by the crank 128 so as to bring the rulers down upon the Work, the lugs 133, 134 contact with the flat face of the part 129, whereby the rulers are yieldingly held in the stated position. When the latter are elevated the arm 125 rides around on the lug 133 until the lug 135 comes into contact with the flat face on the part 129; in which condition the rulers will be held in elevated position.

The apparatus also includes registering mechanism for insuring the proper positioning of the several plates of a series, such as a set of color plates. This mechanism consists of a standard 136 that is set into a hole formed in a plate 137 which is screwed to the base 1. The standard 136 is bifurcated at its upper part and the said bifurcations carry trunnions 138, 139, the former of which is adjustable. These trunnions are adapted to enter recesses in the ends of a shaft 140 for supporting the registering arms. The said arms are denoted by 141 and are of identical construction. Each arm is adapted to be adjustably held in a clamp which comprises two plates 142, 143. The plates 142 are formed integral with bearings 144, that are fixed on the shaft 140. Tail nuts 145 serve to draw the plates 142, 143 toward each other for securing the arms 141 in any desired adjustment therein. The arms 141 have their free ends provided with articulated fingers which are of identical construction so that one only need be described. Each finger has a socket 146 that fits over the end of the arm 1 11 for securing the finger thereon. This socket forms part of the first section 147 of the finger; the other two sections being denoted by 148 and 149. I Each section has its abutting ends enlarged, as clearly shown in Fig. 17, in order to provide broad bearing surfaces; and the parts are held together by bolts 150, 151 which have milled ends 152, 153 threaded thereon for manual operation. Leaf springs 154:, 155 are secured to the sections by screws 156, 157 and bear against washers surrounding the bolts 150, 151 below the nuts, in or der to provide a certain stifi'ness to the joints even when the nuts are loosened. A registering pointer 158 is mounted in the section149 of each finger. An expansion coil spring 159 surrounds each pointer within its section 149, for normally elevating the pointers so as to sheath their points within the said sections. A finger grip 160 on each section 1&9 assists the operator in grasping the fingers and depressing the pointers with his thumbs. In using this adjusting mechanism, the operator loosens the tail nuts 145 and the thumb nuts 152, 153. He then brings the pointers 158 in coincidence with selected spots on the work or with registering points marked thereon. The nuts 14:5, 152 and 153 are then tightened. After this operation the arms 1&1 may be swung outwardly during which movement the shaft 1441 turns on its trunnions 138, 139. When a second plate of a series is placed in position, the arms 1&1 are again lowered, and the plate moved until the previously selected points or particular in dicating points are in register with the points 158. This will insure the exact registering of the second plate with the first;

. and the same procedure may be followed with subsequent plates of the same series. In order to hold the arms l i-1 in their inoperative, elevated position, I provide a spring clamp which includes a member 161 that is pivoted to the standard 136 at 162 and normally urged inwardly by a. retractile coil spring 163 which is connected to the member 161 and anchored to a bracket 16 1 carried by the standard 136. A right angle member having two faces 165, 166 is mounted freely on the shaft 1&0, and is adapted to be secured to a complementary member 167 that is fixed to the shaft 140. The means for securing these two members together consists of a pin 168 that is threaded into a projection on the right angle member 165, 166, and traverses a slot 169 formed in the end of the member 167, and has a tail nut 170 thereon. The slot 169 permits of the said members being adjusted relatively to each other for providing a slight field of adjustment of the pointers 158 toward and away from the work. When the arms 141 are in the lowered position the part 161 engages the face 166 of the right angle member with a yielding pressure for retaining the arms 141 in said position. When the said arms are elevated the part 161 has a similar engagement with the face 165 for a similar purpose.

In order that the registering mechanism may be thrown completely out of the way I provide the standard 136 with a stud 171 carrying a wheel 172 that rides upon a track 173 formed on the plate 137. Abutments 17 4 are formed on the said plate for contact with the stud 171 when the wheel has passed off either end of the track. It will be seen that this arrangement is similar to that of the wheel 51 and its associated parts and that the construction is such that the registering mechanism may be turned through a quarter circle either toward or away from the work table.

In order to accommodate plates of irregular form and to provide convenient means for adjusting them with respect to the registering mechanism, I have devised a holder 175 (see Fig. 1 1) which consists of a frame that is adapted to be seized by the jaws 12 and 13, and held in position on table. The said frame carries three adjusting screws 176, that have heads fitted to slide in grooves formed in the frame. The screws 176 are threaded into the edge of the frame and provided with knurled heads for manual adjustment. It will be seen that, by this arrangement, a small plate, such as that indicated by 177, may be readily moved so as to bring its adjusting points into precise coincidence with the points 158.

A suitable work holding rack 178 may be bolted on the base 1, as shown in Fig. 1, and the stanchion 88 may have a socket 179 and set screw 180 for receiving the end of a rod (not shown) designed to support a light for providing suitable illumination above the work.

I believe that the operation of the apparatus will be clear to anyone skilled in the art from the foregoing description, when taken in-connection with the drawings, but the same may be briefly stated as follows:

The work 14 is clamped in the jaws 12, 13 in the manner described. The rulers 83 are lowered to rest upon the work, and the table is turned by operating the head 66 on the shaft 63 until a selected vertical line or squaring line is parallel with the rulers. The rulers are set, by means of the wheel 100, to the distance apart selected fonthe width of the work. -The rulers are then moved by the crank 128 and bar 85 until they embrace the desired content of the work. Vith a sharp edged tool the work is marked with lines for the cutter to follow in a sub sequent operation. It will be understood that during the procedure just outlined, the table has been in such position that the the desired number of degrees.

wheel 51 is resting against one'of'thestops 53. The operator now moves the table so that the said wheel rests against the other stop 53, which movementwill swing the table through a quarter circle and bring the two other sides of the work under the rulers in order that it may be marked for depth. In this position of the table the procedure above described is repeated. v

In the case of color printing it is frequently desirable to photograph plates at different angles on the copy board so as to obtain desirable screen effects. For instance, one plate may be set at from its normal perpendicular, another 60, etc. However, the said plates must be all squared orlined for squaring so that they will print in the same position. The parts above-described embody means for readily accomplishing this result in that the table may be swung to the right or left of its normal position For in stance, the first plate of a color series may be placed in position in the jaws 12, 13 and squared and lined as already described. When the second plate of the series (which has been photographed at a 30 angle) is placed in the jaws, it is merely necessary to swing the table a distance of 30 in the proper direction, to bring this plate intthe.

desired alinement with the rules. This relatively large swinging movement of the table may be accomplished by seizing the end of the lever 47 and pressing the grip so as to release the pinion 56 from contact with the rack 54, and manually moving the said lever to the right or left as the .case may be. Vhen in approximately the desired position the pinion 56'may again be permitted to mesh with the rack, and the table may be swung to the exact position by turning the head 66 of the shaft 63. In this position the second plate may be lined; and it will be-borne. in mind that this swinging of the table to any extent whatever does'not affect the relationship ofthe table and the lever 47. Hence in whatever position theparts may be, the table is always adapted to be swung through an arc of precisely 90' with respect to the lever 47 so as to present the work in the different positions for lining it as to width and depth. It will be clear that subsequent plates of the color-series, which have been photographed at-yarious other angles, may be handled in a precisely similar manner. I At any desired-time the registering mechanism may be brought into play and used as described. i

It will be understood that various changes may be resorted to in the form, construction, and arrangement of the several parts without departing from the spirit and scope of my invention, and hence I do not intend togbe limited to "the details here- .in shown and described'except as they may be specifically included in the claims.
