MACHINE IORVSLITTING PLIES 0F FABRICS.
v Application led September 28,1921. Serial No.1503,762.
To all whom t may concern:
Be it known that I, DAVID B. ASHMAN, a citizen of the United States of America, and a resident of Baltimore, in the county of .Baltimore City and State of Maryland, have'invented a new and useful Imprcvement in a Machine for Slitting Plies of Fabrics, of which the following is a specification.
This invention relates to a machine for cutting slits in plies of fabrics, and is espe- 4cially .useful in placing the slits in such places `where pockets are vto be formed in garments made from said fabrics.
' A the means described herein and disclosed in,
An object of my invention is to provide a machine for the purpose stated that will be simple in construction and operation, and
that will readily cut through plies of. fabrics of considerable thickness.
a Another object is to provide a device for the purpose'stated which is adapted to slit the .material intermediate the side edges thereof, and which, during such cutting, is adapted to secure the material against movement, whereby neat and trim apertures may be formed in the fabrics preparatory to the formation of the pockets at such places.
These and other objects are attained by the accompanying drawings, in whichvFig l is a side elevation of a device embodying my invention.l
l which a frame a2 supports a knife a", and
means adapted to reciprocate Athe knife,
Y whereby the knife may cut through the fabrios B placed upon the base.`
Thedevice A of my invention comprises a basen having an elongated slot a therein, andupon which is :mounted a frame a2 having arms a3 and a4 which extend over the ,baseV a and terminateV substantially mid i way between the forward and rear ends of the base. tend toward the forward end of the base The free ends of the arms exand'are spaced from one another by means of a brace a5. -The arms have mounted upon them, at their forward ends, the slotted tubes a6 and al. A knife holder as is slidably mounted upon the tubes and supports a downwardly projecting knife a", which knife may be mounted upon said.V holder in any suitable manner. The knife has an angular cutting edge @33. The knife holder has formed in it a vertical way am in which is reciprocally mounted a rod an, the upper end of which rod is mounted upon a cross bar am. The opposite ends 'of the cross bar carry pins ala and a, which pins extend into the slots c and al in the tubes. The knife holder carries pins a and als which extend into the slots als and als. Springs alg and a are disposed within the tubes and the opposite ends of the springs engage the pinsV on the knife support and on the cross bar. A plate @2 mounted on the knife support limits the forward end of the way am and serves to retain the rod in the way al". The rod au carries at its lower end, a slotted pressure foot w21, the slot therein being in the line of reciprocation of the knife 'a9 and of a size that will permit the projection of the knife therethrough. Studs L22 and a eX- tend from the knife support and pivotally mount the levers aztand c25 upon the knife support. The upper ends of the levers are' retained in spaced relation by means of a handle a, and suitable means such as the screws a27 retain the handle upon such levers. The lower ends of the levers are pivotally connected to the upper ends of the links @28 and w29, the lower ends of said links being pivotally mounted upon the forward ends-ofthe arms a3 and a4. The rod au has formed upon it a shoulder a3 which normally engages the upper Surface of the knife support. The rod also has formed on .it a lug am in which is-formed a vertical guide lway in which the knife may be reciprocated and the upper end of the lug a31 forms a shoulder w32 adapted to engage the under surface of the knife support.
The operation of my device is as follows:
Plies of fabric B are inserted between the base ci` and the arms a3 and t in such position that the knife, when being brought downward, will cut the fabrics 1n the desired place. The handle a is then grasped and the levers are moved about their pivotal mounting upon the studs L22 and w23, whereupon the knife support and cross bar are moved downwardly and carry the knife and pressure foot towards the fabrics B. After the pressure foot @21 is brought into engagement with the fabrics B, the springs L19 and a2 retain the pressure foot in yielding engagement upon the fabrics. As the levers 1f/24 and L25 are moved further about their pivotal mountings, the knife engages the fabrics and cuts a slit there-in. The knife may be moved downwardly until the lower surface of they knife support engages the shoulder u32 formed on the lugs @31, whereupon the lever is returned to its normal position as shown in Fig. 2, whereupon the knife is ,withdrawn from the materials B and the pressure foot is elevated thereabove, thereby releasing the fabrics.
IVhat I claim is:
l. In a device for slitting plies of fabrics the combination with a flat base having two spaced apart tubes extending vertically thereabove, of a knife support having a tubular bearing at each end which bearings slide on the exterior of the tubes so as to sustain the support in horizontal position between the tubes, means to reciprocate the knife support upon the tubes, and a depending knife mounted on the support.
