EDWARD R. WILLIAMS AND GEORGE F. D. ROLLINGS. OF WASHINGTON, DISTRICT OF COLUMBIA; SAID ROLLINGS ASSIGNOR TO SAID WILLIAMS.
BURNISI-IING-MACHINE.
To all whom it may concern:
Be it known that we, EDWARD R. 1L- LIAMS and GEORGE F. D. RoLLINcs, citizens of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Burnishingdvlachines, of which the following is a specification.
To prevent the unengraved portions of an engraved plate from printing it is necessary to burnish such portions. The burnishing is at present done by hand with the aid of a hard metal tool which comprises a body having angularly related working edges and a handle secured to the body. At best hand burnishing is slow, tedious, and not productive of the best results.
The primary object of our invention is the provision of a machine which in operation will burnish the unengraved portions of an engraved plate.
A further object of the invention is the provision of a machine which in operation will simultaneously burnish the unengraved portions of several engraved plates.
A further object of the invention is the provision of a burnishing machine wherein the tools shall be under the full control of the operator at all times.
A still further object of the invention is the provision of a burnishing machine which shall be simple and durable of construction, and which may be manufactured and sold at a comparatively low cost.
l/Vith the above and other objects in view the invention consists in the construction combination and arrangement of parts hereinafter fully described and claimed.
The preferred embodiment of the invention is disclosed in the accompanying drawings, wherein Figure 1 is a top plan view of a burnishing machine constructed in accordance with our invention. Fig. 2 is a top plan View of one of the side burnishers. Fig. 3 is a sectional view taken on the vertical plane inclicated on the line 3-3 of Fig. 2. Fig. 4 is a view in side elevation of one of the side burnishers, portions thereof being in vertical section. Fig. 5 is a sectional view taken on the vertical plane indicated by the line 55 of Fig. 4. Fig. 6 is a top plan view of Specification of Letters Patent.

Broadly and generally speaking, the burnishing machine comprises a plate carrier or support, one side burnisher, and two end burnishers. As the side burnishers embody duplicate structures, a description of one will sufice for both.
The plate carrier or support is in the form of a horizontal rectangular bed 1 which is provided at its side edges with downwardly ofiset horizontal flanges 2 and at its rear end edge with a dovetailed guide rib 3. The flanges 2 are coextensive in length with the length of the bed 1 and are provided at their inner ends with rearwardly extending bearing brackets or extensions 2 The guide rib 3 is horizontally disposed, and it is coextensive in length with the width of the bed 1. A dovetailed guide rib 4 is formed upon the upper side and extends longitudinally of each flange 2. Grooves 5, which extend longitudinally of the flanges 2 and of the guide ribs 4, open out through the upper sides of the guide ribs. In its upper side the bed 1 is formed with a plurality of threaded sockets 6 adapted to receive the screws 7 of clamps 8, said clamps securing an engraved plate 9 to the bed.
Each side burnisher comprises a carriage 10 which is provided in its under side with a dovetailed recess 11 receiving the clovetailed guide rib 4 to slidably mount the carriage upon the flange 2. To permit the carriage 10 to be readily applied to and removed from the guide rib 4 andto permit the wear between the carriage and the guide rib to be compensated for, a wear plate 12 is removably secured to one of the side walls of the recess 11 by bolts 13. A feed block 14 which threadedly engages a screw shaft 15, journaled in the groove 5, is secured t0 the carriage 10 through the medium of a bolt 16, the connection between the carriage and the shaft being such that the rotation of the shaft moves the carriage longitudinally of the bed 1, the feed block being illustrated in detail in Fig.18 of the drawings. A power disk 17 is rotatably mounted upon the carria e 10 through the me dium of a round stud 18 which is formed on the under side thereof and which fits in an opening 19 in the carriage, the disk being illustrated in detail in Fig. 17 of the drawings. The stud 18 is provided with a cylindrical socket 20 which receives a round boss 21 formed on the upper side of the feed block 14. The power disk 17 is secured in applied position against accidental displacement by the bolt 16. A bevel gear 22 is keyed to the stud 18 and meshes with a bevel gear 23 splined upon the shaft 15 the connection between the power disk and shaft being such that the rotation of the shaft rotates the power disk. The gear 23 is held in mesh with the gear 22 by a bracket 23" which is secured to the carriage 10 and to the feed block 14. In its upper surface the power disk 17 is provided with a diametrically extending slot 24 which opens at its ends out through the edge of the disk. One side wall of the slot 24 is formed to provide a rack 25. A horizontally disposed shoulder 26 is formed on the other side wall of the slot 24 and a strip 27, which is secured in applied position by means of screws 28, provides a horizontally disposed shoulder 29 on the other side wall of the slot above the rack 25. The shoulders 26 and 29 secure a pinion 30 in the slot 24 against vercal displacement, the pinion meshing with the rack 25. A bolt 31 is formed on the pinion 30 and projects up through the slot 24. An angular support or bracket 32 is secured to the inner side of the carriage 10 by bolts 33 passing through the vertical member 34 of the bracket and entering thecarriage. The horizontal supporting member 35 of sides of the member.
the bracket 32 is disposed above the bed 1 and it is preferably sector shape in outline. In its upper side the horizontal member 35 of the bracket 32 is provided with an arcuate slot 36 which has undercut side walls 37 and which opens at its ends out through the A member or block 38 is adjustably mounted in the slot 36 through the medium of its inclined end edges 39 which enga e the undercut end walls 37 of the slot, sald block being shown in detail in Fig. 15 of the drawings. The block 38 is secured in its adjusted position by means of a set screw 40, which is carried by an eye 41 formed on the block for engagement with the upper side of the horizontal arm 35 of the bracket 32. The block 38 is provided in its upper surface with a slot 42 which opens at its ends out through the ends of the block and in which is mounted for reciprocation a tool carrier 43, the tool carrier being illustrated in detail in Fig. 14 of the drawings.
The tool carrier 43 is secured in the slot 42 of the block 38 against vertical displacement through the medium of its inclined side edges 44 which engage the undercut side walls 45 of the slot. The carrier 43 is provided with a pair of relatively spaced perforated lugs 46 to and between which the inner end of the tool 47 which in its preferred embodiment comprises an elongated body 47 having a working face 47 is pivotally secured, the working face of the tool contacting with the engraved plate 9. A pitman or connecting rod 48 is secured at one end to the bolt 31 through the medium of nuts 49, and the other end thereof is secured to a round stud 50 on the upper side of the block 38 by means of a bolt 50 The connection between the tool carrier 43 and the power disk 17 is such that the rotation of the latter will reciprocate the carrier. The reciprocation of the carrier operates, that is to say, imparts a reciprocatory endwise movement to the tool, and the connection between the tool and the carriage 10 is such that the movement of the carriage will impart a rectilinear sidewise movement to and feed the tool on the plate. The tool is operated in a plane coincident with its length, and its feed is in aplane at an angle to the plane of its feeding movement. The relation of the rectilinear motion of the tool to the reciprocatory motion thereof is approximately in the proportion of one to ten. The combined rectilinear and reciprocatory movements of the tool burnish the unengraved portions of the plate. The working face of the tool 47 is held in contact with the engraved plate 9 by a set screw or bolt 51 carried by an arm 52 and contacting with the tool. The pressure of the tool 47 on the engraved plate 9 may be regulated and varied through the medium of the set screw 51. The arm 52 is pivotally secured to the lugs 16 and is adapted to be held in operative or inoperative position by a spring pressed pin 53, which is carried by the arm for engagement in one of a pair of sockets 54: formed in one of the lugs 16 of the tool carrier 43. When the arm 52 is moved into its inoperative position or when the bolt 51 is turned up a spring 53, secured atone end to the carrier 43 and bearing at its free end on the tool 47, will move and hold the tool up out of contact with the engraved plate 9 permitting the removal of the plate or the cleaning of the tool. The tool can be adjusted horizontally in the arc of a circle by moving the block 38 in the slot 36, and the length of the stroke of the reciprocatory or operating movement imparted to the tool through the rotation of the power disk 17, can be varied by adjusting the bolt 31 with respect to the center of the disk. The bolt 31 may be adjusted through the medium of a crank handle 55 which is secured thereto. As the pinion 30 of the bolt 31 meshes with the rack 25 the turning of the bolt moves itin the direction of or away from the center power disk 17, adjusting the length of the stroke of the operating motion of the tool. The feed and operation of the tool can be thrown out by moving the gears 142 out of engagement with the gear 143, said gears being hereinafter referred to.
Having fully described the side burnishers, we will now describe the end burnisher.
The end burnisher comprises acarriage 56 which is slidably mounted upon the dovetailed guide rib 3, a dovetailed groove 57 being formed on the inner side of the carriage for the reception of the guide rib. The carriage is provided with a recess 58 which opens out through the outer side thereof and with a bearing opening 59 which registers with the recess and which opens out through the upper side of the carriage. A tubular shaft 60 is journaled in the bearing 59 and is provided at its lower end with a bevel gear 61 which is located in the recess 58. A bevel gear 62 is keyed to the upper end of the shaft 60 and meshes with a bevel gear 63 splined upon a shaft G4. The shaft 64: is
journaled in the bearing of a post 65 which.
is secured to and carried by a table or sector gear 66. The sector gear 66 is pivotally secured to the shaft 60 and meshes with a worm 67 keyed upon a shaft 68 journaled in bearings 69 and provided at one end with a removable crank handle 70, the bearings 69 being formed on the rear edges of the flanges 2,
A supporting member, frame or casting shown in detail in Fig. 13 of the drawings, is secured to andcarried by supporting elements or rods 71, said rods being slidably mounted in bearings 72 in the head 73 of a bolt 74 rotatably mounted in the shaft 60, said bolt being secured in applied position by a nut 75. The casting comprises a hollow cylindrical body 76 and a pair of parallel arms 77. At diametrically opposite points the body 76 is provided with a pair of perforated lugs 78 to which the ends of the supporting rods 71 are secured by nuts 79. The bottom wall of the head 76 is provided with a bearing opening 80 which receives the stud 81 of a power disk 82, which is illustrated in detail in Fig. 16 of the drawings. On its under side the power disk 82 is provided with an annular series of gear teeth 83 which mesh with a bevel gear 8&1 secured to the shaft 64. The arms 77 of the casting are provided on their inner sides with guide ribs 85 which are received by guide grooves 86 of a block 87. The block 87 is provided on its upper side with a stud 88 to which one end of a pitman or connecting rod 89 is secured, the other end of the pitman rod or connecting rod being secured to the bolt 90 of a pinion 91. A nut 92 secures the pitman or connecting rod 89 to the bolt 90, and the upper end of the bolt is provided with an angular extension 93 to permit the pinion to be turned by a hand crank, not shown. The pinion 91 is mounted in a slot 9 1 which extends diametrically of the power disk 82 and which opens at its ends out through the edge thereof. One side wall of the slot 9 1 is provided with a horizontally disposed shoulder 95 and the other side wall thereof is provided with a rack 96, with which the pinion 91 meshes. A plate 97 is secured to said other side wall of the slot 94, and it and the shoulder 95 prevent the vertical displace ment of the pinion 91. The connection between the block 87 and the power disk 82 is such that the rotation of the latter will reciprocate the former. By adjusting the pinion 91 with relation to the center of the power disk 82 the length of the stroke of the block 87 can be varied. The pinion 91 is held against accidental movement by a nut 92 carried by the bolt 90 and engaging the shoulder 95 and plate 97. A tool carrier 98 is secured to the block 87 by a bolt 99 threadedly engaging the boss 88. The bolt is provided with an enlarged head 100 upon which the tool carrier 98 is pivotally mounted, and with a milled operating wheel 101 by means of which the bolt may be turned to raise or lower the tool carrier. The tool carrier 98 is held against movement upon the head 100 of the bolt 99 by its engagement with the side wallsof a recess 102 and by means of a latch 103. The recess 102 opens out through the front and bottom sides of the block 87, and the latch 103 is pivotally secured to the block so that it may be swung across the open front side of the recess. WVhen in oper- &
ative position the bolt engages a pin 104 on the block 87 and a projection 105 on the tool carrier. hen it is desired to turn the tool. carrier upon the bolt 99 it is only necessary to throw the latch 103 into inoperative position. A tool 106 which in its preferred embodiment comprises an elongated body 106 having a working face 106 is secured in openings 107 in the carrier 98 by a pin 108. As the tool carrier is pivotally mounted upon the bolt 99 the tool 106 may be thrown up out of engagement with the engraved plate 9 to permit the removal of the plate or the cleaning of the tool. As the bolt 99 threadedly engages the block 87 the pressure of the tool 106 upon the engraved plate 9 can be regulated and varied. On its rear side the body 76 of the casting is provided with a bearing extension 107 to which is removably secured a bearing cap 108, the shaft 64 passing through the bearing formed by the extension and the cap, see Figs. 8 and 13 of the drawings. The bevel gear 63 is spaced from the post by means of a filler 109. The post 65 is secured to the sector 66 by means of bolts 110 and the bearing thereof in which the shaft 64 is journaled is covered by a removable plate 111 which is secured in applied position by bolts 112, s clearly shown in Fig. 10 of the drawings. A screw shaft 113, which is journaled in bearings 114 on the brackets 2, passes freely through the carriage 56, and it is provided with a sleeve 115 splined thereon and located in the recess 58. Beveled gears 116 are fixed upon the sleeve 115, and one or the other thereof is adapted to be meshed with the beveled gear 61 of the shaft 60, whereby the rotation of the shaft 113 rotates the shaft 60, shaft 64, and power disk 82, the rotation of the power disk reciprocating the tool carrier. The movement of the carrier operates the tool, that is to say, imparts a reciprocatory endwise movement thereto. The tool is oper ated in a plane coincident with the length thereof. The sleeve 115 is adapted to be adjusted upon the shaft 113 to move one of the gears 116 into and the other gear 116 out of. engagement with the gear 61 by a hand lever 117. This hand lever is pivotally mounted upon the outer side of the carriage 56, as at 118, and is provided with a fork 117 carried by a collar 119 loosely mounted between annular fianges 120 formed on the sleeve 115. In view of the gears 116 the direction of rotation of the shaft 60 can be changed.
The members of a split nut 121 are mounted in a recess 122 formed in and opening out through the upper side of the head 73. The members of the nut 121 are provided with threaded recesses 123 which engage the threaded portion 124 of the shaft 64, and are connected together by a bolt 125 which is provided with an operating handle 126.
The turning of the bolt 125 in one direction moves the members of the nut out of en gagement with the threaded portion of the shaft and the turning of the bolt in the reverse direction moves the members into engagement with the threaded portion of the shaft. During the rotation of the shaft in one direction and when the members of the nut engage the threaded portion thereof, the casting is moved longitudinally and forwardly over the bed 1. This movement of the casting feeds the tool 106 longitudinally and forwardly on the engraved plate 9. hen the shaft is rotating in the reverse direction and when the members of the nut engage the threaded portion thereof, the casting is moved longitudinally and rearwardly over the bed, feeding the tool longitudinally and rearwardly on the plate. The longitudinal feeds of the tool are each in a plane coincident with the plane of its operating movement. The casting in its forward and rearward feeds is supported and guided by the rods 71. The longitudinal feed of the tool 106 can be thrown out by moving the members of the nut 121 out of engagement with the shaft 64.
The members of split nuts 127 and 128 are respectively mounted in recesses 129 and 130 formed in and opening out through the rear side of the carriage 56. The members of the nuts 127 and 128 are provided with recesses having threads adapted to be engaged with the threads of the shaft 113. The members of the nuts 127 and 128 are connected together by bolts 130, which are provided at their upper ends with cranks 131, said cranks being connected by a rod 132 provided with a hand grip 133. When the rod 132 is moved in one direction the members of the nuts 127-128 are moved out of engagement with the shaft 113 cutting out the transverse movement of the end carriage 56 and the transverse feed of the tool 106. WVhen the rod 132 is moved in a reverse direction the members of the nuts 127-128 are moved into engagement with the shaft 113, whereupon the shaft 113 will, during rotation, move the end carriage 56 transversely of the bed 1 and feed the tool 106 transversely on the engraved plate. The transverse feed of the tool is in a plane at an angle to the plane of its operating movement. This feed of the tool imparts a sidewise motion thereto. The transverse feed of the tool 106 can be thrown out by moving the members of the nuts 127 and 128 out of engagement with the shaft 113. When it is desired to change the direction of the movement of the carriage 54, and consequently the transverse feed of the tool 106, the motor, hereinafter referred to, is reversed.
It should be apparent that it is possible to impart a longitudinal feed, a longitudinal and transverse feed, or a transverse feed to the tool 106. The tool during its longitudinal and transverse feed, its transverse feed, or its longitudinal feed, reciprocates. The feeds of the tool 106 are hereinafter termed rectilinear movements, and these and the reciprocatory or operating movements of the tool burnish the unengraved portions of the engraved plate. The relation of the rectilinear or feeding movements of the tool 106 to the reciprocatory or operating movements thereof, is approximately in the proportion of one to ten. The tool 106 may be horizontally adjusted in the arc of a circle by rotating the shaft 68, and it may be placed on any point of the plate and its position changed through the medium of a pinion 134, which is journaled on the post for engagement with a rack 135 formed on the under side of one of the supporting rods 71, this adjustment of the tool being known as its longitudinal adjustment. The pinion is provided with an operating handle 136.
Before the machine is set in operation, the bolts are turned to force and hold the tools in contact with the plate under grain crushing pressure. In operation of the machine, the movements of the tools burnish the plate, and when found desirable the tools may, owing to their adjust-ability,be positioned to be operated or operated and fed at angles to the grains of the plate. As the feed of the carriage may be thrown out, the tool may be caused to reciprocate for any desired length of time on any portion of the plate. The means for operating this tool may be also thrown out, whereby to permit the tool to be positioned on different points of the plate.
In the operation of the machine, the side tools burnish the unengraved side marginal portions, and the end tool the unengraved end marginal portions of the plate. The tools also burnish those unengraved portions which are located between the unengraved side and the unengraved end marginal portions of the plate. The arcuate adjustability of the tools, the adjustability of the strokes of their reciprocatory or operating movement, and the longitudinal adjustability of theend tool, permit the tools to be adjusted with relation to any curved, straight, or angular engraved line of the plate, whereby during the operation of the machine the tools will burnish those unengraved portions located between the end edges and any of such line or lines of the plate and between any of such lines of the plate.
The machine is adapted to be operated by an electric or other motor 137. A pinion 138, which is keyed on the armature shaft 139 of the motor 137, meshes with a gear wheel 140 fixed on the shaft 113. Sleeves 141 are splined upon the shaft 113 and each is provided with a pair of beveled gears 142. One gear of each pair is adapted to mesh with a bevel gear 143 fixed on the rear extended end 144 of each shaft 15. The sleeves 141 may be moved upon the shaft 113 through the medium of levers (not shown). The connection between the shaft 113 and the shafts 15 is such that rotation of the formed rotates the latter, and such that the direction of retation of the shafts 15 may be changed at the will of the operator. The extensions 144 of the shafts 15 are journaled in bearings 145 formed on the upper side of the brackets 2 It should be apparent from the above description, taken in connection with the accompanying drawings, that the shafts will when in operation move the side carriages longitudinally and the end carriage transversely of the bed; that the movements of the carriages impart rectilinear or feeding movements to the tools; that the rotation of the shaft imparts reciprocating or operating movements to the tools; that the reciprocatory and rectilinear movements of the tools burnish the plate; that the tools may be adjusted with relation to any engraved line of the plate; that the tool may be adjusted at an angle with relation to the grains of the unengraved portions of the plate; that the tools are under the full control of the operator at all times; that the tools may be readily and quickly moved up out of engagement with the plate when it is desired to clean them or remove the plate; and that the pres sure of the tools on the plate may be regulated and varied. It should also be apparent that the machine is simple, durable, and efficient and that it may be manufactured and sold at low cost.
