Application filed. May 27, 1913. Serial No. 770,231.

To all whom it may concern Be it known that I, ISAAC DEATI-IERAGE, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Paper-Gutter Attachments for Tables, of which the following is a specification,

This invention relates to new and useful improvements in paper trimming devices which are adapted to be attached to a suitable supporting table.

One of the objects of this invention is to provide a straight edge which is connected to one edge of a table for lateral movements, and to provide an intermediate support between the table and the cutter or trimmer whereby the paper will be properly supported in position to be out or trimmed.

Another object of the invention is to provide a straight edge of the character described and means for locking the same in any adjusted position, thereby permitting strips of paper of uniform widths to be cut, and a further object is to provide a table with a series of indicating lines arranged at different angles and cooperating with the straight edge to facilitate the cutting of the paper at predetermined angles.

A general object of the invention is to provide an attachment for the purpose set I forth which is extremely simple in construction, and cheap to manufacture.

With these and other objects in view which will more readily appear as the description of the invention proceeds, the same consists in the novel construction, combination and arrangement of the parts hereinafter more fully described, illustrated and claimed.

In the accompanying drawings Figure 1 is a top plan view of apaper supporting table showing the improved trimming device attached to one edge thereof. Fig. 2 is a partial bottom plan view of the same. Fig. 3 is an enlarged cross sectional view taken on the line 3+3 of Fig. 1. Fig. l is a longitudinal sectional view taken on the line 4L t of Fig. 1 and showing the supporting i and operating means for the trimmer. ig. 1 5 is a detail longitudinal sectional view through one of the extensible links of the intermediate paper support taken on the line 5-5 of Fig. 1. Fig. 6 is an elevation of the roller. Fig. 7 is a detail view of the trimmer actuating device.

Similar reference characters designate corresponding parts throughout the several figures of the drawings.

In these drawings, I have illustrated one embodiment of my invention, and have shown the same as comprising generally a straight edge 5 attached to one edge of a suitable table or support 6 and adapted to be bodily moved laterally toward or away from said edge. The straight edge 5 is attached to the table 6 through the medium of a supporting element 7, and this element is secured to the edge of the table and covers a recess 8 formed in said table. The suppor ing element 7 also constitutes a support for a knife blade or trimmer 9 which is mounted for vertical movements in said recess.

The supporting element 7 may be of any suitable character, but in this instance, I have shown the same as being formed from an angle bar, the vertical flange thereof being secured at its ends to the edge of the table or support 6, and the horizontal flange extending inwardly below said support, The straight edge 5 may also be of any suitable character, but I have shown the same as being formed from an angle iron. In order to support this straight edge for bodily lateral movements toward and away from the adjacent edge of the table and in parallel relation thereto, I have provided a pair of swinging supporting links 10-10, each link being disposed directly below the horizontal flange of the supporting element 7 and having its inner end pivotally connected as at 11 with the table 6. The outer end of each link 10 carries an upstanding stud 12 which has rigid connection with the vertical flange of the straight edge 5, the stud having a loose or pivotal connection at 12 with the link to permit said straight edge being adjusted toward or away from the adjacent edge of the table.

When the straight edge is shifted away from the table, there will be a tendency of the paper, which is to be trimmed, to sag, by reason of the space between straight-edge and the table and thereby render the trimming operation more or less difficult. In order to support the paper and thereby avoid this objection, I have provided an in termediate paper support which is connectend of each section opposite its pivoted end able construction, I preferably employ a metal bar 25, this bar being disposed within the recess 8 of the table. Detachably secured to this bar by bolts or any suitable means is a trimming knife 26, the cuttin edge thereof projecting above the top of the bar. This trimmer is normally disposed below the top of thetable 6 and is adapted,

ed to the supporting element 7 and the straight edge 5. This intermediate support consists of a plurality of telescopic or extensible links 13 which are disposed in spaced relation, one section of each link having pivotal connection with the horizontal flange at the straight edge 5 as at 14, and the other section of each link having pivotal connection l l with the supporting element 7 through the medium of the bracket 15 which is connected to said element, the last mentioned pivot being indicated by the numeral 16. In order to retain the sections of each link in longitudinal alinement, the

elevated so that the cutting edge of the knife will project above the top of said table. In order to support the trimmer for this movement, I have provided the bar 25 with a plurality of inclined slots 27, and rigidly supported by the vertical flange of the supporting element 7 are inwardly extending pins or bolts 28 which pass through the slots 27 and support the trimmer. Upon longitudinal movement of the trimmer, the inclined slots will cooperate with the supporting pins to cause said trimmer to move vertically to its operatii e or inoperative position. V 4

In order to oscillate the trimmer longitudinally, I have provided an actuating means, and while this means may be of any suitable character, I have shown the same as comprising a thumb lever 29 which is pivotally connected to the table as at 30, and a link 31 which has pivotal connection at one end as at 32 with the bar 9 and at its other end as at 33 with the thumb lever 29, the last mentioned pivotal connection being eccentric to the pivot 30. As a result upon swinging movement of the thumb lever 29 in either direction, the trimmer will be shifted longitudinally and consequently disposed in either its operative or inoperative position, depending, of course, upon the direction of movement of said thumb lever.

In practice, the straight edge is moved to any predetermined position, and locked by the means above noted. The edge of the paper is then alined with said straight edge, and the thumb lever of the trimmer is ac tuated to project the cutting edge of the knife above the table. which includes a zinc or other soft metal cylinder 35 is employed for severing the strip of paper, the cylinder being rolled over the paper and the cutting edge of the trimmer. Often-times it is desired to cut the paper at different angles, and in order to easily accomplish this work, the table 6 is provided with a plurality of indicating lines 36, these lines being preferably scored in the table and arranged at different angles. One edge of the paper is alined with any one of these indicating lines and the trimmer projected above the table. The paper can then be severed by the roller 34 as above described.

From the foregoing it will be observed that I have provided a trimmer which can be easily attached to a paper supporting is formed with a collar 17 which embraces the other section. WVhen the straight edge 5 is moved inwardly toward the table 6, the link 13 will of course become extended, and when the straight edge is moved directly against the table, these links 13 will be disposed under the horizontal flange of said straight edge and will, of course, be concealed from view. When the straight edge is thus moved, there is a tendency of the links 13 to bind and in order to prevent such action, each adjacent pair of links 13 are pivotally connected by links 18, these links being disposed intermediate and par allel with both the straight edge 5 and the adjacent edge of the table 6.

Should any weight be placed on the straight edge 5 when the latter is in its projected or extended relation, there would be a tendency of injuring the pivots 11 of the links 10, and in order to avoid this objection, I have provided a guard rail 19 which is secured to the under face of the horizontal flange of the supporting element 7, and in spaced relation thereto to permit of the links 10 swinging and at the same time to constitute an offset support for said links.

In practice, it is often necessary to cut strips of paper of uniform widths and in order to retain the straight edge 5 against movement after the same has been properly set, I have provided a locking device therefor. This locking device may be constructed in any suitable manner, but in this instance, I have shown the same as comprising a locking arm 20 which is pivotally connected at one end as at 21 to one of the links 10. The free end of this arm is formed with an inwardly extending longitudinal slot 22 forming a resultant fork. Rigidly secured to the horizontal flange of the supporting element 7 and depending therefrom is a threaded bolt 23 which projects within the slot 22. A winged nut 24- is engageable with said bolt and is adapted to clamp the fork of the arm 20 against the lateral flange of said element 7 and thereby lock the links 10 and consequently the straight edge 5 against movement.
