PATENT CUTTING OB- TRIIVEMING DEVICE.

Application filed July 20, 1925.

v L I My invention relates to an improvement in a cutting or trimming device, and pertains more particularly to what is commonly known to photographers as a print trimmer.

The primary object of the invention is the provision of a print trimmer of a construction whereby a vast amount time is saved in the trimming of photographic prints by reason of the fact that the first cut or trim of the print is always correctly made.

Another object of the invention is the provision of a print trimmer which when in use frames the image or picture on the print in light and thereby enables the proper trimming of the print.

A further object of the invention is the provision of a print trimmer of the character described which is provided with a quickly and easily adjusted gauge.

A still further object of the invention is the provision of a print trimming device in which the trimmings are directed into and received by a receptacle.

A still further object of the invention is the provision of a print trimmer in which the trimming knife is held normally in a raised position, whereby it is ready for action or operation at all times.

Another and further objectof the invention is the provision of a cabinet which carries a print trimmer of the character described, which is of a construction to provide a place for receiving prints to be trimmed and a place for receiving the prints after the same have been trimmed.

Other further objects, novel features of construction and improved results of the invention will appear from the following description and accompanying drawings.

In the drawings:

Figure 1 is a perspective view of a print trimmer constructed in accordance with the invention.

Fig. 2 is a top view of the construction appearing in Fig. 1.

Fig. 3 is a vertical sectional view of the device.

In carrying out the invention there is provided a cabinet A, which may be of any desired shape or size to meet the necessary de mands to which it will be subjected. In the embodiment of the invention, as shown in the drawings, the cabinet A is of a simple and plain construction, being provided with suitable legs 5 of a length to make the top 6 of the cabinet of a proper height to enable Serial No. 44,944.

the trimming device to be used by operators of the average stature. The cabinet A has its interior divided into two parts. he lower part of the cabinet is adapted to slidably receive a drawer 7. The upper portion of the cabinet is in communication with the drawer bv reason of an open bottom 8. The top 6 of the cabinet serves as a cover for the upper top portion of the cabinet. The cabinet top (3 is provided with an opening 9, which extends from the point 10 which is adjacent one edge of the top to a point 11. Suitably mounted within the cabinet upper portion, as at 12, is an electric light 13, which is adapted to throw light against the inclined board or partition 14-, which is provided with an outer white or suitable refleeting surface 15. The light is reflected upwardly, by the reflecting board, through the opening 9 in the cabinet top.

Suitably mounted upon the cabinet top 6, by means of brackets 16 or the like, at its front edge and a strip 17 at its rear edge is an open frame 18. This open frame 13 car ries a suitable transparent plate, preferahly glass, as designated at 19. Mounted upon the rear edge of the fran'ie 18 is a rule 20, the markings upon which face towards the front of the cabinet.

The trimming knife is designated at 21, and is provided with a suitable handle The lower end of the knife is provided with a hub 23, which is pivotally supported upon the shaft 2t, carried by the bearing of the bracket 26, which is suitably fastened to the strip 17 as at 27. To allow lateral movement of the knife, its shaft support 24 is provided with a common spring construction 28. By reason of the coiled spring 29, the knife is normally held in a raised position.

One edge of the frame 18 is provided with a metal or cutting member 30, which is adapted to co-operate with the knife 21 when the same is pulled downwardly. As clearly appears in the clrawing, the cutting member and the knife 21 are positioned above the opening 9 in the cabinet top.

The gauge 31 extends longitudinally be low the glass top 19 and is suppor ed upon the plate 32, the outer end 33 of which is internally threaded and supported upon the threaded gauge rod 34, which is rotatably supported as at 35 and provided at its outer end with a suitable thumb or hand screw 36.

The cabinet is provided at its left side with a shelf 37, and at its right side with wardly through the opening Operation.

The operation of the device is quite simpl'e, being as follows: The electric light is connected with a suitable source of supply so that it will throw light against the reflecting surface 15, and the board 14 in turn throws this, light upwardly through the opening 9,. sothat the glass or transparent plate is illuminated. I

Theprints being trimmed are preferably upon the shelf 37 and the gauge 31 1s positioned, by means of the thumb-screw 36 the proper distance from the cutting edge 30. The distance of the gauge from the cutting edge 30 always is apparent by reason of the rule 20. It will be readily understood that'the gauge istherefore positioned the proper distance from the cutting edge 30 so that an 8 x 10 or 6 X 8 print can be trimmed.

'Let us, assume that we are trimming a 6 X8 print. It is desirable to trim the print 011 its long edges first and the gauge would therefore be positioned opposite the numeral 6 on the rule.

Immediately that the print is placed on the illuminated glass 19, the print will be framed in light between the edge of the opening frame 18 and theedge of the gauge 31. This fran'iing of the print in light makes it possible to determine immediately how much of a cut it is desired to take off the edge of'the print adjacent the knifeor cut ting edge 30, as it will be readily apparent by looking at the other edge of the print how much of the print it will be necessary to cuton the second cutting. As soon as the print is properly framed in the light, the knife 21 is grasped and pulled downwardly-"thus cutting one long edge of the print, The print is then reversed and the cat ed e isi'nline with the gauge with the Shea 'ec ie ef the print abutting the rule 20 The second out is then made.

the print along its-long edges is repeated nntiihtwecuttings are'made atthetwo short edges of the prlnt.

The severed edges of the print will fall downwardly through the opening 9 and travel down the face of the slanting board saves a great many prints. When the first cut is made improperly, the print is often lost because before the cuts can be remade to properly trim the print, the print has been reduced to such a small size that it is worthless.

It will also be readily understood that the prints or work of any sizecan be framed in light by adjusting the gauge to the proper position.

With the use of my device, the print in reality is framed prior to trimming it to the desired size and by thus framing the print it is possible to visualize immediately the correct manner in which the print should be trimmed. This is not possible in trimmers now known upon the market.

Although there is no door shown in the drawings to close the open front of the upper space 1d of the cabinet, it will be readily understood that the completed cabinet will be provided with such a door. The door has been left off in view of the draw ings so that the interior arrangement of the cabinet can be more clearly seen.
