This invention relates to a curtain roll cutter, and more particularly to improved means for cutting such a roll so as toflt the previously measured window casing.

One feature of this invention is that it provides means for accurately determining the point'at which said roll is to be cut; another featurev of this invention is that it provides guide means at said point for a saw or other cutting tool; vstill another feature of this invention is that it pro'- vides positive means for holding the curtain roll without danger of slippage or change of position A when it is being cut; yet another feature of this invention is that it is adapted to receive all commercial sizes and diameters of 'curtain rolls; another feature is that two scales are provided, one for inside brackets and :the other for outside brackets; a still further feature of thisinvention is that the device may be set directly at the measured width of the window casing, allowance being automatically made for the tips of each end of the roll and the necessary slack or play; other features and advantages of this invention will vbe apparent from the following specification and the drawing, in whichto brackets mounted on such casings, therefore,

it is necessary to measure the distance between each casing and to cut the curtain roll and curtain to t that particular window. It has long been customary in the trade to measure the casing width, make allowances for the tips and the necessary slack, mark a curtain roll by hand with a yardstick or tape, and then saw it by hand. Many errors occurred in this mode of operation, and it is not at all infrequent for 30% of the curtain rolls cut in this way to iit improperly. Sometimes they may be used even though they have too much or too little slack, but frequently they are so far oif as not to fit at all.

corresponding toy the width of the window. It has mounted at one end of the scale a supporting block for the curtain roll, with a guide slot'for a saw or the like at the point vat which the curtain roll is to be'cut, determined by placing one end. 5

of it against the block previously set to Ycorrespond to the window width. :The device is so arranged thatv necessaryY allowances for the tipsA and vfor slack is automatically made for both'V inside and n n outside brackets. a Y

In the particular embodimentof this invention illustrated herewith, an `elongated base I0 of wood'orsirnilar material is here shown as of' rectangular shape. 'Ihe base has atone end thereof a supporting block I I having therein a supporting 15 slot `I2 adapted to have a curtain roll Alie therein and' be longitudinally slidable therethrough when Y said rollfis parallelto the long'axis of the basel Theblock I I has a second or guide slot I3 therethrough `'atfright angles to the slot I2. YThis slot 20 is so constructed and arranged to'actas-aguide for a saw for cutting the roll, or other instrument for marking it. k

The base has slidably mounted thereon a block I 4, which'block is here shown as mounted by a 25 bolt I5 projecting through a central longitudinal slot I6 in the base, provided at the upper end thereof above the block I4 with a wing nut Il for manually locking the block at any desired point on the base. The block is also here shown with a. spring I 8 for frictionally retaining it. Y

while the wing nut is being tightened. It is to be understood, of course, that this spring is optional and that'any convenient slidable mounting and locking means may be employed. enable the block to slide readily along the base Without the head of the bolt I5 striking a table I.

or other place on which the base may be laid, blocks. I9 and 2l) are provided at the ends of the base to elevate it slightly above the surface on 40 which it rests.

The base has graduated thereon the two scales 2| and 22, in linear units'here shown as inches. While these scales are both graduated in the same units, it will be noted that they are not in registry with each other, nor do their zero points coin-V cide exactly with the guide slot I3. The scale 2|, intended for use where inside brackets are tobe mounted on the window casing haa if.: am

In order to 35 porting slot I2 in the block II is 1%," in width throughout a part o-r portion of. the length, but

has a reduced lower portion 23 one inch in width. The wider portion of the slot thus receives 1% rolls, while the reduced portion will receive and support inch or rolls. The block I4 has mounted on the face thereof, directed toward the block I l, brackets 24 and 25. Both ofthesebrackets are located in a position which corresponds to the center of the supporting slot I2, but they are vertically displaced, the bracket 24 being at such a height as to coincide withv the center of a. roll supported inthe wider portion of the slot I2; while the bracket 25, being somewhat lower, coincides with the center of a smaller roll lying inthe reduced portion 23. Y

Where it is desired to use thisl device to cut a curtain roll to t a previously measured window casing, it is first determined Whether inside or outside brackets are to be used. vThe bracket edge of the block I4 is then set at a measured distance on the scale corresponding to the brackets to be used, and locked in place by tightening the wing nut I'I.v Avcurtainroll o ithe desired diameter then vhas a tip placed on one end thereof, and the curtain roll locked in the slot I2 with the tip mounted in the bracket 24 or 25, depend-- ing upon the diameter of the roll. A saw isthen inserted in the slot I3 and the roll cut, thus'providing an accurately located squarely cut edge.v A cap and tip are then placed on this end of the roll, and it is ready to be mounted on the window casing for which it was intended.

While I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims, in which it is my intention to claim all novelty inherent in my invention as broadly as permissible, in view of the prior art. .i `What I claim as new and desire to secure by Letters Patent is: Y 1. A device-'ofthe character described for determining a point 'at which a curtain roll is to be cut, including: an elongated base having two .linear scales rgraduated thereon in the same units but aboute out of registry with each other; a block on one end of said base having a supporting'slot'therethrough parallel to said scales and a guideslot therethrough perpendicular to said scales, said guide slot being located between the zero points of said'scales, the distance bef tween the zero pointsy and said guide slot Vbeing adapted to compensate for inside and outside curtain roll brackets; a second block slidably mounted on said base adjacent said scales and adaptedv to be set at a predetermined desired graduation on either of said scales; means for locking said block at the point at which it is set; and means on said slidable block for supporting one end of said roll when said roll lies in said supportingslot. Y l g 2. Apparatus of the character claimed in claim 1, wherein said supporting slot has a portion fof reduced width near the bottom thereof, and said slidable block hastwo supporting kmeans thereon each of'saidV supporting meansrbeing vadapted to engage the tip mounted on a. curtain roll;
