The main object of the prese-.nt invention is the provision of a printing frameand mat strips to cooperate therewith, the frame being arranged. to permit the mat Strips to be clamped in such rela-,ted positions. with,V
each other and with. the negative as to. formA any size mat for the negative within the limits of the frame,
The invention in its preferred form of dei-A.
tails willI be described 4in the 'following specification, reference being had tothe ac"- companying drawings, in which* y Figure l is a plan, View of the improved printing frame. Fig. 2 is an end. elevation thereof. Fig. 8 `is a section on line "3-3a of l. Referring particularly t0 the accompanying drawings, my improved printing rame comprises two rectangular skeleton'frames hereinafter designated as the upper frame 1- and the lower frame 2. Theseframes are arranged in superimposed relation and* maintained spaced by corner blocks 4t thereby providing channels or spaces 5 between the proximate surfaces of the upper and lower frames throughout theindengths and widths except at the corner blocks. The lower frame is formed throughout its inner edge with an inward` extension A6 rabbetedA at 7 throughout its upper surface to receive the usual glass 8of the printing frame,'the depth of the rabbet corresponding approxi' mately to the thickness of the glassused.
The up er frame is formed throughout the end and3 side' pieces with-'longitudinally.disposed channels -extending vertically through the end and side pieces, the lower ends of the channels being laterally enlarged in both directions to form receiving grooves 10 of increased width as compared with `the channels.
As thus described it vwill he noted that the having veach arm chanhelscentrally overlie the upper surfaces of,l the sidey and, elidpi'cces of the lower frame, it being understood; that the walls. 1,1,v and l2 of' the channels [5,whf0zh Walls are formed by thev lower- 'surface of theupper Ahe freni@ bers and by the upper surfaces 0 lower frame bars arefn pl'l'allelisxa Slide-bly mounted in the channels 9 are what I term @lame members. 1.3, Said, members Cen'sttilting. c

As thus arranged the Clamp members are normally held with their clamp plates 1 4 in engagement with the upper sur'- faces 0f the frame bars ol,A the lower frame by 'll-:e tension of the s 16, said'clamp members baila-f,` afliusta, le'lensitildnelly t0' any position' 0f., a Particular frame b ,r through. the Mii-1.1m.v of; the lifting bars 1. tbene Obvious that' by en upward Jill' 0n. the lftin'gbar the Pilatell may'- be ifted from the surface of the lower frame bar andthe. 'clamp ber. then moved' longitunella in Ithe geile sie 9 td any desired positionv Que clamp. member is used prefL erably in each slot"9though I contemplate ythe use of any number shouldsuch be found desirable; The usual' clamping'back 17' is.

being held bythe usual springstrips 18 and hooked projections 19, the latter being properly 'secured on theupper frame, as shown.
In connection with' the improved printing -frame I use mat strips 20, preferably right angled sections ofy opaque material raduated, as shown. In use the negative 1s laid 'upon the glass in the usual manner. The mat strips are then placedin position being introduced throu h the channels so that one arm of each strip will project through the channel formed by Athe end pieces ofthe frames and the other arm' of each stri projecting through the chanels formed y the side pieces of the frames. The strips are arranged in opposing relation as shown 'so that their respective arms-intersect. The strips are now adjusted by means of their graduations to ioo lfl
the printing paper.- The form a mat of the desired size, accuracy and alinement being maintained through the graduations sov that vcorresponding arms of the respective mat strips will register with the same graduations on the opposing arms. After this adjustment the clamp members are moved longitudinally vof theirtive underl ing said strips is also heldagainst accidental moving when ,applying printing paper being thenA applied in the usual manner the backis secured in place andthe printing.
operation carried out.
It will be noted that a mat of any desired size` limited only bythe size of the frame being used can be secured as the. particular strips may be of any width and need not necessarily be ri ht angled strips but can be arranged in di erent forms to secure different effects, the sole requirement in this particular being that' the mat strips be so constructed thatv they may. beclamped in place against accidental movement a ter bein arranged to provide the desired mat.
1. The combination with a printing frame, of mat stripscomprisn angularly related arms, and means-carrie by the frame for clamping the respective arms to maintain the mat'strips in adjusted relation to provide mats of different sizes.
2. A printing frame including an upper' and lower frame maintained spaced relation to provide channels, the Y'upper frame tween said clamp being formed with guide slots overlying the surface of the lower frame,y clamp members operable in the guide slots and coperating with'the upper surface of the lower frame, and matstrips Wholly free of connection with the frame and adapted to be engaged by the clamp member.
3. A printing framel including two rec- `tangular frames maintained in spaced relation to provide intervenlng channels, ithe upper frame being formed with longitudinally disposed slots in the sides and ends thereof overlying the lower frame, clamp members including clamping plates and liftling bars slidably. positioned in said slots, said .plates being adapted to bear on the upper surface of the lower frame, and mat strips' wholly free of connection with the frame'and adapted to be engaged by said plates.
