rArnR-oirrrxNeTi/rAcHINE.

Be it known that we, Lno T. CURRAN and JAMES H. XVIDENER, citizens of theUnited States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a certain new and useful Improvement in Paper-Cutting Machines, of

which the following isa specification,

Our invention relates to improvements in paper cutting machines.

The object of our invention is to provide machine with a gage mech-' a paper cutting anism which may be quickly adjusted to po-: sitions suitable for gaging sheets of paper of different sizes, and which may bequickly adjusted to positions in which the paper may be cut at various angles to its edges.

()ur invention is adapted to be used in connection with the ordinary back gage of a paper cutting machine, and is arranged so as to be quickly swung into or out of operative position, so as to permit the use of the ordinary back gage when desired.

Other novel features of our invention are hereinafter fully described and claimed.

In the accompanying drawings which illustratethe preferred embodiment of our invention, Figure 1 is a vertical sectional view on the line 1-1 of Fig. 2, showing the pivoted gages resting upon, the table. Fig. 2 is a plan view of our improved gage mechanism. Fig. 3 is a front elevation of the gage mechanism, the table being shown in vertical section. Fig. 1 is an enlarged horizontal section on the line 4-4: of Fig. 3. Fig. 5 is a perspective viewxof one of the slide blocks. Fig. 6 is an enlarged vertical sectional view on the line 6-6 of Fig. 1. Fig. 7 is an enlarged vertical sectional view 011 the plane of the line 77 of Fig. 1, the gage being shown in the extended position.

Similar reference characters designate similar parts in the different views.

1 designates the table of an ordinary paper cutting machine, 2 the knife and 3 the usual back gagel 4-. designates the usual clamping bolt which is adjustable in the slot 5 of the table 1.

6 designates a right-angled supporting member provided with two rearwardly extending arms 7 which are respectively pivoted by transverse bolts'8 to two brackets 9 which are secured to and extend obliquely upwardly and rearwardly from the back the rightparallel with respectively respectively 7 Specification of Letters Patent.

angled supporting. member 6 is provided with a longitudinal slot 10 which'is disposed the knife 2. The upper side of thehoriz ontal portion of the member 6 is provided with a'longitudinal guide 11 which is slidably fitted in transverse grooves 12 which are provided respectively in the under sides of two blocks 18, oneof which is shown in Fig. 5, which are slidably mounted on the member 6.

Two gage supporting memberslt are re. spectively mounted on the blocks 13 and are provided on their under sides with longitudinal grooves 15, Fig; 1, in which are respectively slidablyfitted raised portions .16, Fig. 5. -Tl1e gage supporting members 1 1 are respectively provided with longitudinal slots 17 through which extend A vertical bolts 18, which also extend through the slot 10 andthrough two vertical holes 19 provided respectively in the blocks 13, as shown in Fig 5. I

Slidably mounted on the gage supporting members 14E respectively are two washers 20 mounted respectively on the bolts 18." 7

Two nuts 21, preferably in the form of hand wheels, are respectively fitted on the screw-threaded upper ends of the bolts 18, and are adapted to bear against the clamping washers 20 respectively. The lower ends of the bolts 18 are provided with heads which bear against the under side of the horizontal portion of the supporting member 6. g

Each supporting member 14 at its for ward end extends downwardly, the lower end being provided with a horizontal portion 22. Two vertical bolts 23 extend respectively through said horizontal portions 22, and have respectively pivoted to them two right-angled gage members 24, each of which is provided with two transverse holes in which are respectively mounted two horizontal parallel bars 25 and 26 which are disposed parallel with the lmife 2.

Set screws 27 and 28 mounted in the member 24: serve to hold the bars 25 and 2,6 in said member 2 1. i I

Two nuts 29 are respectively mounted on the screw-threaded'upper ends of the bolts 23, and are adapted to clampingly engage the members 24.

Adjustably mounted and longitudinally slidable on the bars 25 and 26 are two gage I may be made Without respectively set screws 32 and 33 adapted to respectively bear against the rods 26 and 25. p p H By loosening the nuts 21, thesupporting members 14 may be movedtogether Withthe gage members 24 parallel with and at rightanglcs to the knife 2. By loosening the nuts 29, the gage members 24:, 30 and 31 may be swung toany desired angle Within the limits of the mechanism.

When it is desired to use the gage memhers 24, 30 and 31, said members are dis posed, as shown in the drawings, upon the table 1. hen it is desired to use the back' gage 3 for gaging paper, the supporting member 6 together w th. the parts carried thereby may be swung upwardly and rear- Wardly upon the pins 8, so as to leave a clear field in front of the back gage 3.

w e do not limit our invention to the structure shown and described, as modifications, Within the scopeoi' the appended claims, departing from the spirit of our invention. I 7

Having thus described our invention, What we claim and desire to secure by Letters Pat eiit, is r 1. In a paper cutting machine, a sup: porting member having a longitudinal slot, a block slidable :on said supporting member parallel With said slot and having a vertical hole in alinement With said slot, a gage supporting member slidable on said block transversely to said slot, and provided With longitudinal slot extending across and at right angles to the slot in said supporting member, and in alincment with. said hole in said block, a clamping device extending through said slots and through said hole and having means for clamping together said block, said gage supporting device and said supporting member, and a gage pivoted on a vertical axis to said gage supporting member.

2. Ina paper cutting machine, a back gage, a supporting member, a gage pivoted on a vertical axis to said supporting member, a member pivoted on a horizontal axis to said back gage and upon which said supporting member is movable forwardly and laterally, and means for releasably clamping said two members together.

Intestimony whereof We have signed our names to this specification in presence 01' two subscribing Witnesses.
