GUSTAVE REUBEN OLSON, OF PLATTSMOUTI-I, NEBRASKA.

GAGE FOR PRINT-HOLDING FRAMES.

Application filed November 28, 1910.

To all 10 1 am it may concern:

Be it known that I, GUSTAVE R. OLsoN, a citizen of the United States, residing at Plattsmouth, in the county of Cass and State of Nebraska, have invented certain new and useful Improvements in Gages for Print- Holding Frames, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to a gage for positioning a sensitized sheet of paper upon a photographic plate.

The invention has for its primary object the provision of a very simple device of the above character which will quickly and properly position the sensitized print paper on the negative to be engaged and held in position by suitable holding means.

Another object of my invention resides in the provision of a gage having adjustable print engaging arms and means for raising and lowering said arms to engage the same upon a photographic plate and to remove said arms therefrom without disturbing the position of the printing sheet.

A still further object of the invention is to provide a device for the purpose specified consisting of a body member and a bar adjustable with relation thereto, and right angularly extending gage arms mounted on said bar and adjustable independently of the same.

Another object of the invention is to provide a positioning gage for photographic printing sheets which is extremely simple in construction, highly efficient in practical use, and one which may be manufactured at a comparatively low cost.

With the above and other objects in view, the invention consists of the novel features of construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a gage embodying my improvements illustrating its arrangement with relation to the print sheet and negative holder; Fig. 2 is a similar view showing the gage in operative position; Fig. 3 is an elevation partly in section showing the two positions of the gage arms in Specification of Letters Patent.

the operation of the device; and Fig. 4 is a detail perspective view of the print sheet positioning arms.

Referring in detail to the drawings 5 designates the body of a photographic printing machine upon which the print paper and negative holding device 6 are arranged. Both the printing machine and the holding device are specifically described and shown in separate copending applications for patent which are filed coincident herewith. The same will not therefore be described in detail in the present specification.

The gage or positioning device which I have devised for positioning the sensitized printing sheet upon the photographic negative plate, embodies in its construction a body member 7, which is pivotally mounted upon the frame or body of the printing machine as designated at 8. The gage may, however, be entirely separate and distinct from the printing machine and mounted for movement upon a portable base, and arranged in the proper position with relation to the holder 6 in the use of the device. The free end of the member 7 is bifurcated as shown at 7 to receive the end portion 9 of the adjustable carrier bar 9. The end of this bar is also slotted or bifurcated as indicated at 9 to receive a portion 7 of the member 7 which is provided by the provision of the slot or bifurcation 7 in the end thereof. Thus it will be seen that the ends of the member 7 and bar 9 are provided with co-engaging mortises and tenons. A connecting rod 10 extends through these co-engaged end portions of the bar 9 and member 7 to connect the same for relative pivotal movement whereby the bar 9 may be disposed at various angles with relation to the member 7. The bifurcated end of the member 7 through which the rod 10 extends is split as shown at 11, and one of these split end portions has disposed therethrough a clamping screw 12 upon the end of which a nut 13 is threaded. By adjusting this nut upon the screw, the split end portion of the member 7 is securely clamped upon the rod 10 to rigidly secure the bar 9 in its adjusted position with respect to said member. It will be observed that the rod 10 extends a considerable distance below the lower edge of the member 7. The purpose of this extended portion of the connecting rod will more fully hereinafter appear. The other or free end of the bar 9 is also bifurcated as indicated at 14L and through this bifurcated end the rod 15 is vertically movable.

Upon the lower end of the rod 15 below he bar 9, the right angularly disposed print sheet positioning arms 16 are arranged. These arms are rigidly secured together and a clamp 17 is carried by the same for engagement with the rod 15. This clamp is fixed upon the rod by means of the clamping screw 18 on the end of which a nut 19 is threaded. It will thus be apparent that the arms 16 may be easily and quickly adjusted to position the same with respect to the bar 9.

The print sheet positioning arms 16 are adapted to be vertically adjusted to permit of the bodily movement of the over the negative, for positioning the arms upon the same and for removing the gage after the print sheet has been positioned. This adjusting means includes a bell crank lever 20 which 'is pivoted upon one side of the bar 9 as at 21. One arm of this lever extends into the bifurcated end 1st of the bar and is pivoted to the vertically movable rod 15 as indicated at 22. To the otner end of the bell crank lever 20, one end of a rod 23 is connected, the other end of said rod being disposed through an opening in the substantially triangular plate which is fixed at one of its vertices upon the lower end portion of the rod 10, beneath the body member 7. The rod 23 is connected to one of the other vertices of the plate and to the remaining vertex, one end of an operating rod 25 is connected. This rod may be connected to the print sheet and negative holding device to automatically raise and lower the arms 16, or it may be operated by hand. It will be ob vious that when the rod 25 is pulled or moved away from the bar 9, the rod 15 will be elevated in the end of said bar to raise the print sheet adjusting arms 16 to the position shown in dotted lines in Fig. 3. Upon reversing the movement of the rod 25, the bell crank lever 20 will be moved through the rod 15 downwardly and lower the arms 16 into contact with the negative as shown by the dotted lines in Fig. 3. This lowering movement of the arms takes place at the end of the swinging pivotal movement of the gage, and when the arms are positioned over the negative. Thus scraping or sliding movement on the arms on the negative is prevented. The sensitized printing sheet is placed in position with its edges engaging said arms, thus insuring the proper arrangement of the sheet upon the negative plate. In removing the gage to engage the holding device upon the print sheet and negative, the arms 16 are first raised vertically and the gage then bodily swung upon its pivot outwardly as shown in Fig. 1.

Upon the printing machine case or other stationary support, a link 26 is pivoted at one end, and to the other end thereof the end of a rod 27 is pivotally connected. The rod 27 is bent upon itself as indicated at 28 to provide the parallel portions which are disposed upon opposite sides of a belt 29 fixed in the machine case or support. Upon the end of the bolt 29 a wing nut 30 is threaded for clamping engagement upon the parallel portions of the rod 27. By sliding the rod 2'? upon the bolt 29, the link 26 may be swung upon its pivot to position the same for engagement by the lower end of the rod 10 which connects the member 7 and arm 9 of the gage, whereby the swinging movement of said gage to position the arms 16 over the negative is limited. By adjusting the link 26 and securing the same rigidly in its adjusted position by clamping the nut 30 upon the rod 27, the arms 16 may be properly disposed over the negative to centrally arrange the printing sheet thereon or to position the same upon any other portion of the plate surface.

From the foregoing it is thought that the construction and operation of my improved will be readily understood.

The device is very eflicient and reliable in its operation and will accurately arrange the printing sheet in the desired position on the photrgraphic plate, thus eliminating the care and attention heretofore necessary in making photographic prints, and also saving considerable time. By adjusting the bar 9 the printing sheet may be properly positioned longitudinally upon the negative plate, the arms 16 insuring the proper parallel relation of the edges of the plate to the print sheet. The adjustable stop link 26 provides for the transverse disposition of the printing sheet upon the negative.

Owing to the comparatively few elements employed in the construction of .the gage, it will be obvious that the same will be very durable in practical use and that it can also be manufactured at a low cost.

While I have shown and described the preferred construction and arrangement of the various elements, it will be obvious that the device is susceptible of considerable modification without departing from the essential feature or sacrificing any of the ad antages of the invention.
