10 Claims.

This invention relates to improvements in setup tables, particularly set-up tables for spacing machines. For example, the invention may be employed in connection with paper cutting machines having spacing means for locating the various cuts. The invention however would be entirely applicable for use in connection with machines for boring or punching holes at given positions in a sheet, strip or bar, or for performing other work at predetermined intervals upon sheets, strips or bars of various materials.

One of the objects of the present invention is the provision of auxiliary set-up means which may be employed to properly locate and fix points of operation along a stop bar, which bar may then be transferred bodily to the operating machine to control the spacing movements of the machine, whereby the set-up for one job may be accomplished while the previous job is being performed in the machine, thereby conserving the operating time of the machine, reducing the overhead accordingly, and enabling a shop to turn out a given amount of work with fewer machines than would be required otherwise.

Another object of the invention is the provision of means for making a set-up of a stop bar outside of the machine in which it is to be used, where the stops act to control, that is to open or close, an electric control circuit.

Other objects and features of novelty will appear as I proceed with the description of that embodiment of the invention which, for the purposes of the present application, I have illustrated in the accompanying drawings, in which Fig. l is a plan View of the set-up table with a stop bar mounted therein.

Fig. 2 is an end view of the table and associated parts.

Fig. 11 is a plan view of a sheet of paper with the lines of cut marked thereupon to illustrate the character of work which may be done upon a paper cutting machine in connection with which the present invention may be employed.

Referring to the drawings, I provide a table I0 which may be supported on suitable legs (not shown) or may be supported upon a bench. This table is adapted to support a whole work sample. which is represented at I I. Where the invention is used in connection with a paper cutting machine, this work sample will consist of a strip of paper taken from one of the sheets which are to be cut up in the machine. The lines of out are indicated on the work sample by the dot and dash lines a and b. The work sample is lined up against a side gauge l2 and caused to abut against an end stop It. The latter corresponds in position to the rearmost position of the back gauge of a paper cutting machine. When the work sheet has been properly positioned in this manner it is held against movement by a clamp, which comprises a long bar I l that is carried by the ends of two arms l5, each of which is pivotally mounted in rearwardly extending ears !6 of the table. When the clamp is not in use it may be swung backwardly out of the way.

In the table it, forward of the side gauge I2, I form two guide grooves or ways ll and Hi. the groove ll being dove-tailed, and the groove l8 having outwardly flared sides. These grooves are parallel to each other and to the side gauge l2. I9 is a bracket which is adapted to slide in these grooves. It may be locked in any desired position of adjustment by set screws 2!! which take into a dove-tailed clamping bar 2! running in the groove H. A depending rib 22 forming an integral part of the bracket runs in groove 28 and assists in holding the bracket in proper alignment. At its forward end bracket l9 carries a cone pointed pin 23 similar to the dead center of a lathe. A second cone pointed pin 24 is carried by an arm 25 projecting forwardly from the opposite end of table In. The pin 25 however is adjustable in the arm 25, being threaded to receive nuts 26 and 21 which may be tightened to lock the pin 24 against movement. The pins 23 and 24 are in alignment and their axis is parallel with grooves I! and i8 and with side gauge l2. They are adapted to receive a stop bar 28 which in the present instance is shown as of square cross section, having conical cavities in its extremities for the reception of the pins 23 and 24. In each side of the bar 28 there is a groove 29 with flaring sides and a dove-tail groove 30. The stop bar may be held in any one of four different angular positions by a lever 3| mounted in the bracket l9, which lever has a projection 32 adapted to take into any one of the four grooves 30. A coil spring 33 serves to hold the lever yieldably in operative position.

Each side of the bar 28 is adapted to receive a set of stops corresponding to a series of cuts in a paper sheet. In accordance with the present disclosure there are certain major stops A and. certain auxiliary stops B. The stops A are used for the principal cuts, indicated at a on Fig. 1, while the stops B mark the trim-out cuts, indicated at b on Fig. 1. Stops A are mounted directly upon the bar 28. They each have integral projections 3 3 running in grooves 29 and carry separate dove-tail clamping pieces 35. The latter are operated by screws 36 which extend through smooth bores in the stop members A and into thread d openings in the clamping pieces .35. When the screws 36 are loosened the stops may be sl d al e th ba t a es ed t on. nd when the proper position of adjustment is reached the screws are tightened to lock the stops in place. Eachstop A carries a disk 3'! of metal which is preferably insulated from the remainder of the stop by a fiber washer 31', see Fig. 10.

Each stop A has two vthreadedhcles 38 therein, in either one of which a screw .SQmay be mounted. Across the face of the stop there is also a groove 45. Auxiliary stop B has a rearwardly extending rib 5i fitting the groove 45, and a slot 42 adapted to receive the screw 39. By projecting the screw through the slot .42, setting it in one or the other of the two holes 38, and by moving the stop B laterally within the limits permitted by the slot 92, any desired spacing of the two stops with respect to each other may be effected. Stop B at its upper ,end carries a metal disk .43 which is preferably insulated from the .rest of the stop, as in the case of disk 31, and is of the same size and shape as disk 31 but, as will be noted from Fig. 6, is situated ina plane forward of the plane of disk 3 StopsB are used only when two stop Positions a clo er t the han the h rt possible spacing of two steps A.

On the trackprovidedbyguides or ways i! and t8, and to one ,side of the bracket l9, I mount a carrier 55 which is movable along the said track in the same way as bracket l9, being provided with the same kind of grooveengaging elements,

. and being adapted to belockedin any desired position of, adjustment by a setscrew 45.

The carrier is provided on its rear side with .a transverse beveledrule or position indicator .4] which runs over the side gauge I2 and over the edge of the work sample ll. By means f this position indicator the carrier 45 may be .brpught into accurateregister with anydesired line 9f cut on the work sample. The carrier 45 may carry a pair of dry cells stand 99 and an electric signal, such as a lamp 50. The carrier al so includes a forwardly extending arm '5! ;in which is supported a pivot pin 52. On thelatter there are oscillatably'mounted two arms 53 and 54. Coil springs 55 and 56 tend to depress the outer ends of these arms, but their movement in that direction is checked by stop screws 57 which are mounted in a bar 58 extending forwardly from the arm 5! The arm 53 carries a pair of spaced metal contacts 59 and supported upon bolts El and 62, which are insulated from the contacts by fiber washers '53. If desired, the latter may be 'held against rotation by locking pins 54, and the disks 59 and 59 may be held against turning movement by being locked to the washers 53 by means of key 55. When the disk 37 of stop A is brought into precisely the proper position the two contacts 59 and 69 engage the disk 3'! simultaneously and are thereby electrically connected. As soon as there is any relative movement of the slide with respect to the stop however the engagement of one of the contacts 59 and .69 with the disk 31 is interrupted and the electrical connection between the two contacts is broken.

The arm 59 supports two spaced contacts 66 and -61 which are mounted and insulated in the same manner .as the contacts 59 and 69. They are adapted to engage the disk 43 of a stop B and to be thereby connected electrically in the same manner as ,above described with respect to the contacts 59 and 6B.

The two contacts 69 and 61 have flexible leads 58 and 59 soldered thereto. These leads are connected in parallel with an electric conductor H1 which may extend to one terminal of the electric lamp '59. From the other terminal of this lamp a conductor H extends to the battery cell 48. A short conductor l2 connects the two cells 99 and 19, and a further conductor 73 extends from cell 99 back to another pair of flexible leads 14 and "55 which are soldered to the contacts 59 and 65, respectively. Obviously, therefore, if either the rear pair of contacts 59 and are electrically connected together by a disk 37, orthe forward pair 66 and 57 are connected by a disk 43, the circuit through the battery and the lamp 59 will be completed and the lamp will be lighted.

Operation.-In order to explain the operation of the present apparatus, let us assume that we have a large quantity of sheets of paper, each sheet having printed thereupon a considerable number of labels or the like, as indicated by the division lines in Fig. 11. The first step in proceeding to set up the job for operation upon a spacing and cutting machine, is to place a number of stops A upon each of four sides of a stop bar 28, and mount the bar between the pin centers 23 and 24. Then the operator removes a strip of paper from a sample sheet by cutting it along a line located somewhat as is the dot and dash line 15. This strip of paper is then placed upon the set-up table in the position of the work sample I! of Fig. 1, with the edge Tl adjacent the side gauge 52 and the edge l8 against theend stop H3. The operator then loosens set screw and moves the carrier 45 along its track until the edge of position indicator ll comes directly over the first out line 19a. He now turns down set screw 56 to lock the slide in that position temporarily. The operator then moves the foremost stop A on the forward side of bar 28 until its disk 31 comes directly between the contacts 59 and 60. when the lamp 5!) will b lighted. The arms 53 and 54 are permitted to yield, or swing upwardly, as the disk 31 of the stop moves under one .of the contacts 59 and 60. The operator thereupon tightensscrew 35, which secures :the stop in that position. Next he again loosens screw 45 and moves carrier 45 to the left until position indicator 41 registers withthe next out line 89a, when ing thelamp "50, when the -stop is locked to the stop bar. The next out line Mb is situated only a short distance from the cut lineBDa, and this 15 distance being less than the width of a stop A, it is impossible to employ a stop A to define or mark the cut line Bib. The operator moves the carrier 45 to cause the position indicator 4! to register with line Blbz He then mounts a stop B on the A stop last mentioned, and whlie the screw 39 is loosened, moves the stop B along until it bridges the contacts 66 and 61 on the forward arm 54, whereupon the electric circuit is completed and the lamp is energized. The screw 39 is now tightened down, locking this stop B in place. The operator then proceeds in like manner to set a stop A for out line 82a and a stop B for out line 83b.

The operator now takes another sample sheet, and cuts it on the lines 19a and 80a and places it on table in the position heretofore described, with the edge 19a against the side gauge l2. He then presses down on lever 3! and turns the bar 28 through a quarter revolution, bringing a new side thereof into position beneath the arms 53, 54 and their contacts. The carrier 45 is then moved to the right hand end of the table and is set to register successively with cut lines 84a, 85a, 86a, 87a, 88b, and 89a. This completes the set-up for another series of cuts to be made upon the spacing and cutting machine.

In a similar manner the stop bar is turned through a further quarter revolution, a new work sample consisting of a strip of paper out along the lines Bib and 82a is placed in position on the table, and stops are set on the stop bar corresponding to the cut lines 9002, 9lb, 92a, 93b, 94a and 95b, after which the stop bar is again turned through a quarter revolution, a new strip of paper with side edges 83b and 18 is placed on the table and stops set for the cut lines 96a, 91a, 98a, 99a, llllla, and I0! a, it being understood that stops A are used to correspond with all of the cut lines on the drawings marked with the sufiix a, while stops B are used to correspond with all of the cut lines marked with the sufiix b. v

The stop bar is now set up for four difierent complete series of cuts, which is sufficient to handle all of the work of cutting labels from the sheet illustrated in Fig. 11. The position of any given out is noted on the scale l2. The stop bar is now removed from the set-up table and mounted in a spacing and cutting machine, after which it is adjusted longitudinally until the noted cut comes at a point on the scale of the cutting machine which corresponds to the noted point on the set-up table. No other adjustment is neces sary. With the stop bar in the proper angular position in the cutting machine, all of the sheets are run through the machine to make the cuts 19a, 80a, 8Ib, 82a, and 83?), which results in three sets of paper strips.

The stop bar 28 is then turned through a quarter revolution in the machine, and the stops for cutting the lowermost strip, as viewed in Fig. 11, are brought into operative position. All of these lowermost strips are now put through the machine. Next the stop bar is turned through another quarter revolution and the next set of strips are cut into their ultimate pieces, after which the stop bar is again rotated and all of the strips of the last set are cut up.

Of course it may not always be possible to obtain the necessary set-up for a given job with four sets of cuts, and in such cases more than one stop bar will have to be employed. In some cases also it may be advisible to use a stop bar which is formed to receive one set of stops only,

or one which is formed to receive a plurality of sets other than four.

It will also be apparent that my set-up table can be employed for setting up work to be performed on different sizes of cutting machines, since stop" bars 28 of different lengths may be accommodated by merely moving the bracket [9 along its track to the desired position.

Furthermore, the invention in its broader aspects contemplates relative movement broadly between the carrier 45 on the one hand and the Work sample and stop bar on the other hand. That is to say, the carrier 45 may be made stationary if desired, while the holder for the work sample and the mounting for the stop bar may be caused to move together past the carrier 45.

Variations from the described structure may be employed. Accordingly I desire it to be understood that the scope of the invention is to be regarded as defined by the appended claims rather than by the foregoing description and the accompanying illustrations.
