SPECIFICATION forming part of Letters Patent No. 669,882, dated March 12, 1901.

Application filed January 10, 1900. Serial No. 997. (N model.)

r the platen, and means for adjusting the lower feedgage both laterally and longitudinally of the platen.

The details of the invention will be set forth hereinafter, and the novel features thereof will be defined in the claims.

In the drawings forming part of this specification, Figure 1 is a perspective View of the platen of a job-printing press with my improvements applied. Fig. 2 is a plan view of a portion of the press, showing the platen in an upright position just approaching the type from which the impression is to be made. Fig. 3 is a vertical sectional viewof the platen, the section being taken just to one side of the gage and gripper, on the left side thereof. Fig. 4 is a detail perspective view of the two parts of a clamp employed for securing the gage and gripper to the frame on which they are mounted. Fig. 5 is a rear or lower edge View of the attachment carrying my improvements.

Like reference-numerals indicate like parts in the different views.

The platen 1 may be of any suitable form and construction, having secured to the front or upper face thereof the tympan-sheet 2, the latter being bent or folded around the edges of said platen and held in place thereon by a clamp 3 in the form of a band made up of two bail-shaped strips 4 and 5, pivoted at their ends to the side edges of the platen 1. The said clamping-band is of the usual construction and holds the tympan-sheet 2 in place on the platen l by friction. Also frictionally secured to the platenl, outside the tympansheet 2, is a gage-strip 7, of metal or other suitable material, having its end bent downwardly to form the flanges 8, engaged by the bails 4 and 5, of which the clamp 3 is made spring 12.

up. The said strip 7 has attached to it the gage for the left-hand edge of' the sheet 9-to be printed, the said gage being made up of a plate 10, connected to the strip 7 by the doule hinges 11 and normally held upwardly away from the strip 7 by means of a leaf- It will thus be seen by reference to Figs. 1 and 3 of the drawings that the plate of the gage is normally held in its raised or projecting position, but that it is adapted to be compressed against the action of the spring 12 on the hinges 11. The said hinges 11 may be of any suitable form or construction. They may consist, if desired, merely of links pivoted at their opposite ends to the strip 7 and plate 10, which will provide for the approach or compression of said plate 10 toward said strip.

Removably secured to the platen l, at the lower edge thereof, is a bracket 13, consisting of a plate having downwardly-extending flanges 14 thereon, which are engaged by the bail 5 of which the clamp or band 3 is made for the purpose of securing said bracket to said platen. The said plate is further provided with elongated slots 15 15 on opposite sides of the center thereof and with downwardly-extending lugs or ears 16 at its endsandintermediateportions. Adjust-ably mounted on the bracket 13 are the grippers 17 18 and the

gages

19 and 20 for the lower edge of the sheet 9. For connecting these parts to said bracket I employ two clamps, one on each side of the centerof said bracket, each composed of a lower member 21, having a downwardly-projecting screw-threaded lug or car 22 on its under side and an upwardlyprojecting rectilinear rib 23 on its upper side, and an upper member 24., having a clam pingscrew 25 extending therethrough andengaging a corresponding opening in the lower member 21 and having recesses 26 27 in its lower surface, for a purpose which will presently appear. Said member 24 is further provided with a pin or projection 28, adapted to fitwithin an opening 29 in the lower member 21 for the purpose of retaining these parts in proper relative position. The rib 23 on the lower member 21 is of the same width as the slot 15 in the bracket 13 and fits within said slot, so that the movements of said clamp in one direction or the other will be guided by the engagement of said rib with the sides of said slot. The

grippers

17 and 18 are each made up of three hinged sections, the lower section 30 thereof fitting within the recess '26 of the clamp member 24 and secured to the bracket 13 by said clamp. Theintermediat'e section 31 of the gripper is hinged or pivoted, as shown at 32, to the section 30 and is adapted to move upwardly therefrom away from the platen 1. The section 33 of said gripper is hinged or pivoted, as shown at 34, to the upper end of the section 31 and normally lies in the position shown in Figs. 1 and 3 of the drawingsthat is, with its free end projecting toward the bed 35 of the press and toward the lower edge of said platen. The same is formed with a curved outer end 36 and is resiliently held in the position described by means of a leaf-spring 37. The normal position of the section 31 of said gripper is also as shown in Figs. 1 and 3 of the drawings-that is, with the upper or free end thereof elevated from the platen and resiliently held in its position by means of a leafspring 38, secured within the recess 26 of the clamp to the bracket 13, projecting outwardly therefrom and engaging the under side of the section 31 a short distance from the hinge or pivotal point 32. The

grippers

17 and 18 are both of the same form and construction, except that the gripper 17 is formed with an elongated slot 39 therein, providing for the passage of the plate 10 of the left-hand feedgage therethrough, it' being understood, of course, that the gripper 1'7 is located directly above said left-hand gage. As ordinarily 'no gage is employed for the opposite side of the sheet to be printed, the necessity for a corresponding slot in the gripper 18 is removed.

From the foregoing description it will be noted that the

grippers

17 and 18 normally project away from the face of the platen 1, v or rather the tympan-sheet thereon, so that the sheet 9 to be printed may be readily in- It will also be observed, however,

serted. that the different parts of said grippers are yieldingly mounted and connected with each other, so that during the forward movement of the platen in the printing operation when said platen approaches or reaches a substantially verticalposition said grippers, or rather the curved ends 36 of the sections 33 thereof,

will come in contact with the furniture and yield or be compressed in order to provide for the approach of the platen l, carrying the:

sheet 9 to the type 40.

The bottom gages 19 and 20 for the sheet 9 to be printed are both of substantially the same construction, except that the bearing faces or edges thereof project in opposite directions from their stems. Each of said gages is made up of aplate 41, constituting its stem, and having a laterally-extending plate or arm 42 on one end thereof. Hinged at its opposite ends to the arm 42 is a plate 43, similar in all respects to the plate 10, heretofore described, and normally maintained in its upper or raised position by means of the leafspring 44". The connecting-hinges between the arm 42 and the plate 43 may be of any suitable form and construction which provides for the depression or movement of said plate toward and away from said arm against the action of the spring 44. The stem 41 of the gage fits within the recess 27 in the under side of the clamp member 24 and is held in place on the bracket 13 by means of said clamp. In order, however, to provide for the bodily movement of said clam p on the bracket 13 without disengaging the stem 41 therefrom, I interpose between the member 24 of said clamp and the upper face of said stem a curved leaf-spring 45. This spring provides for the movement of the stem 41 in the clamp by which it is secured, so as to bring the plate 43 of said gage nearer to or farther away from the lower edge of the platen 1. It also provides for the bodily movement of said clamp on the bracket 13 without disturbing the relations between said stem and said clamp. It will thus be seen that the bottom gages are adjustable both laterally and longitudinally of the platen 1. In the longitudinal movements of the stem 41 the same is guided by the engagement of the sideedges of said stem with the inner side walls of the recess 27.

In order to provide for the lateral movement of the securing-clamps forthe gages and grippers, I mount on the under side of the bracket 13 screw-threaded bolts 46, the same being supported in the lugs or ears 16 on said bracket and provided with handles or operating-wheels 47 on their outer projecting ends. The ears 16 permit the rotary movement of said bolts, but prevent the longitudinal movement thereof. The said bolts extend through and -engage the threads in the openings in the lugs 22 on the under side of the sections 2101' said clamps, so that by turning one of said bolts in one direction or the other a movement of the corresponding clamp transversely of the platen 1 in one direction or the other will be effected. In this bodily movement of either one of the clamps the sameis guided by the engagement. of the rib 23 thereon with the side walls of the slot 15, in which said rib fits.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. Afeed-gage for printing-presses, consisting of a body, a plate pivoted thereto, and located above the same and a spring for normally maintaining said plate away from said body.

2. A feed gage for printing-presses, consisting of'a body, a plate located above and hinged to said body so that it may be moved toward the same, and a spring interposed between said body and plate for holding the latter normally away from said plate.

, 3. Afeed-gage for printing-presses,consisting of a stem for the attachment of the same to the platen, a laterally-extending arm thereon, a plate hinged to said arm at its opposite ends, providing for the compression of the same toward said arm, and a leaf-spring secured to said arm and engaging the under side of said plate for normally maintaining the latter away from said arm.

4. In a printing-press, a plurality of feedgages, means for separately adjusting the same vertically or longitudinally of the platen, and engaging means for said gages for moving the same horizontally or transversely of the platen without affecting their vertical position and for locking them in adjusted position.

5. In a printing-press, a plurality of feedgages, clamps for securing said gages to the platen, means engaging said clamps for moving them horizontally or transversely of the platen and for locking them in adjusted position, and means independent of their horizontal movement for adjusting said gages in said clamps vertically or longitudinally of said platen.

6. In a printing-press, the combination with a platen and a clamping-band embracing the same, of a bracket having projections thereon fitting between said platen and said band and thereby secured to said platen by said band, a plurality of feed-gages, means for securing said gages to said bracket, means for inde pendently adjusting said gages vertically or longitudinally of said platen, and engaging means on said bracket for moving said gages horizontally or transversely of the platen and for locking them in adjusted position.

7. In a printing-press,the combination with a platen and a clamping-band embracing the same, of a bracket secured to said platen by said band, a feed-gage and a clamp for securing said gage to said bracket, said clamp comprising a lower member having a lug thereon provided with a screw-threaded opening and an upper member havinga recess for receiving the stem of said gage, a spring interposed between said stem and one of the members of said clamp, whereby said gage may be adjusted at right'angles to said bracket, and a screw-threaded bolt extending through the opening in the lug on the lower member of said clamp for moving said clamp and the parts carried thereby longitudinally on said bracket.

8. In a printing-press,the combination with a platen and a clamping-band embracing the same, of a bracket secured to said platen by said band provided with an elongated slot therein, a feed-gage, a clamp for securing said gage to said bracket and in which said gage is adjustable, the said clamp consisting of a lower member having a rectilinear rib on its upper surface, fitting within the slot in said bracket, and an upper memlper having a recess in itslower side adapted to receive the stem of said gage, and means for moving said clamp longitudinally of said bracket.

9. In a printing-press,the combination with a platen and a clamping-band extending around the edges thereof, of a gage-strip having flanges on the ends thereof engaged by said clamping-band for holding said strip on said platen, and a yielding feed-gage on said strip, consisting of a plate located above and hinged at its opposite ends to said strip, providing for the depression of the same toward said strip and a spring interposed between said strip and said plate for normally maintaining the latter away from the former.

10. In a printing-press,the combination with a platen, of a bracket removably secured thereto, a yielding feed-gage, a yielding gripper, a clamp for securing said feed-gage and gripper to said bracket, means for adjusting said feed-gage in said clamp independently of said gripper, and means for moving said clamp bodily on said bracket at right angles to the direction of adjustment of said feedgage in said clamp.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
