SHADE-TRIMMER.

Specification ofjLetters Patent.

Patented Sept. 15, 1908.-

Application filed May 4', 1908. Serial No. 430,691.

To all whom it may concern:

Be it known that I, HENRY MERGER FISH- ERING, a citizen'of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented a new and useful Improvement in Shade1rimmers, of

which the following is a specification.

The invention relates to a machine for trimming the edge of a shade to a desired width and also for gaging the place for cutting ofi the end of the stick on which the shade is mounted. In'devices of this class, it is customary to place the stick, with the shade fastened and rolled thereon, in suitable bearings,-and to locate a cutting knife ation.

Another object of the improvement, is to provide means for adjusting the knife and or throwing and looking it out of contact is conveniently rotated for the cutting operwith the shade roll when the trimming has been done; and to provide a base with ad- 'ustable slides therein for one of the shade rings and. for the cutting knife, together with clamps for both slides, and an extension scale or measure for the knife slide.

A further object of the improvement is to provide a yoke support for the protruding 3 end of thesha'de stick, which maybe adjusted against the trimmed edge of the shade, thus forming a. suitable gage against" which the superfluous portion of the stick can be cut off.

The invention, thus described in general terms, is illustrated inthe accompanying drawings-forming art hereof, in which- Figure 1 is a pan view of the trimming machine showing a. shade mounted on its stick in position for being trimmed by the cuttin knife; Fig. 2, an enlarged cross section 0 the same on line 2-2, Fig. 1, showposition of the knife whenunlocked and impinging the side of the shade roll at the beginning of the cutting operation; Fi 3, a similar section showing the position 0 the knife at the completion. of the cut; Fig. 4, an enlarged fragmentary lan view of the cutting knife at ,the comp etion of the cut; Fig. 5, an enlarged longitudinal section on line 5-5, Fig. 1, showing the yoke gage in position for cutting off the end of the stick.

Similar numerals refer to similar parts throughout the drawings.

. The base-board 1 is provided with the two parallel

longitudinal guide grooves

2 and 3,. which are preferably dovetailed in cross section, and in which grooves the bearing slide 4 and the knife slide 5 are located and adapted to operate. The ordinary cam-clam s 6 are located in the recesses 7 in the sides 0 the base-board adjacent to the res ective slides,

by means of which clamps t e slides are adapted to be locked in any desired position. T e fixed bearing 8 is provided on one end .of the base-board, directly over the line of the bearing slide, and the adjustable bearing 9 is provided on the opposite end of the same slide; the fixed bearing being adapted to receive the pivot 10 located in the spring end of the shade stick l1, and the adjustab e bearing being adapted to receive the fixed pivot 12 on the other end of the shade stick-the end on which the shade is usually trimmed and from which the surplus length of the stick is cut. It is evident that the shade stick, with the shade 13 rolled thereon, can be readily placed in the machine first inserting the spring pivot of the stick in the fixed bearing and then by suitably sliding the adjustable bearing to receive the fixed pivot on the other end of the stick; in which position the adjustable bearing is locked by 0 er-ating one or more of the clamps against t e side of its slide. The elastic bands or ri s 14 are preferably clamped around the s e roll, one near each end, forthe purpose of keeping the same tightly rolled while the shade is being trimmect and the stick out off the ring near the end of the shade to be trimmed being located inside the proposed trimmed end of the roll.

The knife bracket 15 is formed or attached I head-2O of the knife arm, in which slot the :impress'the knife pointfagainst and into the .sidel'oitthe shade roll by means of the com- ,paratively strongspring23, which is preferably inthe form of. aspiralspring located around; the hub 24 of the knife arm; and for I normally holding the knife away. from the ;roll,.thes ring latch25 isprovided on the.

knife brac et and is-adapted toengage the 20 26 on the side of the kniferarrn, when the fe is rotated away, from the curtain roll, asshown in Fig. 2.

- ,Theprimary measuring scale'27isfprovided on the faceof the base-board along the outer side :of the knife slide, and this scale begins atizero, located at a point opposite the edge of. the shade=on the spring end of the stick, and extends thence preferably a dis- Y so . tance .of 24inches, theksame being designated ,ininchesfrom Ito-24. The extension scale 28 is provided on the face of-thle knife slide, and beginsatthe knife and thence extendsin 'a reverse direction along thegprimary scale, a distance of'24 inches, the same beingdesignated in inches from 24; to4 8Q It is evident vthat when the knife; slide is moved one way -,its', distancez in inches from the edge, of the. curtain on thespring end of thestick, is indithe knife=slide is moved the; other way,- the" V-distance of the knife from the same edge of the curtain is indicated by the numberon the extension scale which registers with the arrow-located at 24 inches in theprimary scale, this distancefbeing 34 inches as" illustrated in fitting a shade for-a desired-width of window, the next, width of shade material in I excess of the desired-width is selected from stock, and the same is fastened and rolledzon a stick-which is likewise of the next stock length in: excessof-the properlength, one
