1 Claim. 1

The present invention relates to thread markers for cloth and the like and it consists in the combinations, constructions and arrangements of parts herein described and claimed.

Generally, the invention relates to an apparatus for simultaneous marking on each of a plurality of layers of fabrics or other suitable material, such as cutout parts which are intended for assembly into a completed article such as a garment. Such apparatus may be utilized for the marking of pockets, button holes, lapels and the like.

In carrying out the invention, there is provided a mechanism which will perforate and carry through a layer of cloth or the like a thread and which has means for automatically grasping the thread after it has passed through such layer and means for holding the same until the thread inserting means has been withdrawn, whereby a single or double thread is left in the layer of cloth and thereafter cut ofi at each individual piece of cloth to leave a short protuberance of thread whereby to mark a particular spot on such individual piece of cloth or the like.

It is accordingly an object of the invention to provide a simple mechanism for the marking of layers of cloth by means of a thread.

A further object of the invention is the provision of a mechanism of the character described which will be simple in its construction, easy to manufacture and which will be simple yet eflicient in its operation.

Another object of the invention is the provision of a novel means and mechanism for the retaining of a thread in a layer of cloth or the like after the same has been forced into such layer.

A further object of the invention is the provision of a novel means for holding the layer of cloth or the like when the same is penetrated with a needle for inserting a thread therethrough.

Another object of the invention is the provision of a novel locking means for the apparatus whereby a needle may be retained at will in the cloth layers after penetration therethrough.

A further object of the invention is the provision of a. manually operated means for grasping the thread after it has penetrated the layers of cloth to be marked thereby.

Another object of the invention is the provision of a novel manually operated means whereby the locking means above referred to may be released.

For further comprehension of the invention,

and of the objects and advantages thereof, ref-/ erence will be had to the following description and accompanying drawing, and to the appended invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 8 is a top plan view of the device shown in Fig. 1.

Fig. 9 is a vertical sectional view of a of the device.

Fig. 10 is an enlarged sectional view taken along line Ill-10 of Fig. 4 locking in the direction of the arrows thereof.

Referring more particularly to the drawing, there is shown therein a thread marking appara tus comprising a base Iii, an overhanging arm l2 attached at its lower end to the back of the base [0 and terminating at its free end in a journal l3. with a plurality of reinforcing ribs H which are for the purpose of providing greater strength to the structure and also for the attachment of various mechanisms thereto, which mechanisms will be hereinafLer more fully described.

To the upper side of the arm I2 there is afiiXed a bracket It to the upper end of which is pivoted, as indicated at iii, a lever comprisingan outer portion l6, and an inner telescoping member ll. The outer portion I6 is fulcrumed at l8 and is provided with a handle l9 at its free end. The lever is provided with a depending arm 20 having an angular extension 2i integrally connected therewith and provided with a pair of ad'- iustably connected pawls 22 and 23 Afiixed to the rear of the arm 12 and extending upwardly therefrom is a spool holder 24 and a platform 25 associatedtherewith and carrying an outwardly-extending arm 26 to which is adjustably connected, by means of a thumbscrew 21, a thread guide 28 having a looped upper end 29. The spool holder 24 is adapted to receive a spool of thread 30 thereon, as shown in dot and dash lines in Figs. 3 and 6 which thread is portion The base 10 is provided on its under side adapted to pass through the looped upper end 29 and thence through a guide member 68 having a horizontally disposed hole 69 therein for the reception of the thread.

The pawls 22 and 23 are adapted to engage ratchet teeth 3| and 42 successively upon a downward movement of the handle I9. The ratchet teeth are formed in an arm 33 which is hinged at one end, as indicated .at 34, to a lever 35 and terminates in a handle portion 36 at its other end, which handle portion is provided with a protruding handle 31. A guide bracket 38 is affixed to the arm l2 by means of a pair of screws 39 and the handle portion 36 is vertically slidably supported by the guide bracket 38 so that the arm 33 may pivot slightly about its hinged end 34 within the top and bottom limits of the guide bracket 38. A spring 40 interconnects the upper screw 39 and a screw 4| carried by the arm 33 :rearwardly of the guide bracket .33 to maintain the 'armnormall-y in a forward position and in a raised pivoted position against the top portion of the guide bracket-38, as shown inFlg. l. .The lever 35 is pivoted centrally, as indicated at 42, to the rear portion of the arm -|2 and is adapted to have its lower end bear against a stop 43 carried by a sliding member All which is mounted for reciprocal .movement in the base l upon a pair of laterally extending supports 55 and -46. A spring 41 interconnects .the member 44 and the support 46 to normally urge'the'member rearwardly. The forward end of the member -44 has attached thereto a substantially U-shaped bracket 46, one side of which, 49, is elongated to act as a guide and the other side. 50, of which adjustably carries a .hook

The fulcrum 18 of the outer portion N5 of the lever is carried by an annular collar 52 ,on an upper cylindrical member 53 which is provided with a threaded top member 154 to which is aiiixed a shaft 55 and to the lower end of which is affixed a needle :56 adapted to receive the end of the thread 39 in the usual eye opening '51.

The needle 56 has its upper end secured to the bottom end of the shaft 55 by the usual coupling tube 55%. The tube 55 'issecured to the bottom end .of the :shaft 55 by a set screw 55 and the upper end of the needle 56 is secured in position finthetube 55 'bya-set screw 55.

The uppercylindricalmember 53 telescopes the upper end of a lower cylindrical member 58. The bottom portion of the lower cylindrical member 58 is projected through the journal i3 and is secured thereto by an upper lock nut 63 and 'a lower lock nut 64. Fixedly mounted in the bottom end of the lower cylindrical-memberEB there is-a bushing 58. see'Fig. 9.

Disposed within the lower cylindrical member 58, there is a tube 59 having an outside diameter less than the inside diameter of the lower cylindrical member. The top end of the tube 59 is formed with an outwardly directed flange 59 which slidably engages the'innerface of the lower cylindrical member 58. The bottom end of the tube 59 is slidably projected through the bushing '58 and has 'threadedly mounted on the bottom endthereofa presser foot 6 The presser foot 6| is locked to the-end of the tube 59 by a "lock nut "6P *which also engages the bottom end of the lower cylindrical "member 55 limiting "upward movement of'the tube 5.9.and presser'foot 5| relativeto-the cylindrical-member 58. The tube 59 is retained in a;raised position by a :coil spring .62 which engaged concentrically about the tube downward movement.

4 59 and which operates between the adjacent faces of the bushing 58 and the flange 59 The upper cylindrical member 53 (and in turn the operating lever) is urged into a raised position relative to the lower cylindrical member 58 by a coil spring which surrounds the shaft 55 and which operates between the top member 54 and the top face of the flange 59 The spring 60 .is somewhat stronger than the spring 62 so that when the lever is pivoted downward about its pivot l5 for engaging the end of the needle 56 through a stack of cloth, the upper cylindrical member 53 and the tube 59 will move downward as a unit compressing the spring 62, until the presser foot 6| engages the top of the stack of cloth. Downward movement of the tube 59 will be stopped, but downward movement of the upper cylindrical member 53 will continue, compressing parts to the normal position shown in :Fig. 49.

The bracket 38 is provided with an integrally formed laterally extending .handle 65 and the arm 33 is provided with the laterally extending handle'3'i.

In operation, it will be seen that when it is desired to mark particular spots in a stack of fabrics to be cut-into, for example, garments such as coats and the like, the stack of fabrics will be placed on the base and the proper spot marked on the uppermost fabric. This spot is then positioned immediately below the needle 56 whereupon the handle IB is brought downwardly.

When the handle -.|"9 is moved downwar ly, from the full line position shown in Fig. l, the upper cylindrical member 53 will move downwardly carrying the needle 56 and the pressure foot 6! therewith, against'the action of the'spring 52. Downward movement of the pressure "foot-6| will continue until it engages the topmost layer of thelayers of cloth resting onthe base It, which will hold the pressure foot 6| against further Continued downward movement of the handle 49 will cause the needle 56 to carry the thread .36 completelythrough the layers of cloth.

At the start of downward movement :of the handle i9, the pawl '22 engages the top face of the arm 33 and rides along that top face pivoting the arm 33 downward about its hinged :end .34

and against the action of the spring 46 until the pawl 22 engages the ratchet tooth3| whereupon continued downwardmovement of the handle l9 causes the pawl 22 to move the arm 33 rearward against the action of the spring 40 pivoting the lever 35 about its pivot 42, causing its lower end to move forward and bear against the stop-t3 of the sliding member 54, and urge the sliding member 44 forward against the action of the spring 41. As the pointed end of the needle 56 carrying the thread 33 passes through the top wall of the base, as shown in Fig. 10, the sliding member 44 will assume the full forward position, shown in dot and dash lines in Fig. 4, in which the pointed end or the hook 5| will be forward of the bottom end of the needle, having passed the needle 56 at one side thereof.

As the handle l9 nearly reaches its completely depressed position, the position shown in full lines in Fig. 3, a slight further downward movement causes the pawl 22 to ride clear of the ratchet tooth 3| freeing the arm 33 to slide forward very slightly under the influence of the spring 46, and instantly urges the pawl '23 into the ratchet tooth 32 arresting further forward movement of the arm 33 by the spring 40. In addition to drawing the arm 33 forward, the spring 40 also urges the arm 33 upward about its hinged end 34 to retain the respective pawls and ratchet teeth engaged.

After the fully depressed position of the handle I9 is reached, it is released so that the spring 60 raises the upper cylindrical member 53. Immediately at the start of the upward motion, the pawl 22 engages the top edge of the arm 33 rearward of the ratchet tooth 3i. As the pawl 22 is now disposed rearward of the pivot I5, see Fig. 3, and has a normal position forward of the pivot I5, see Fig. l, the pawl moves in a downward arc until it passes beneath the pivot I 5. As the pawl 22 immediately engages the top edge of the arm 33 its movement in a downward arc, to pass beneath the pivot l5, causes the arm 33 to be pivoted downward against the action of the spring 40 and about its hinged end 34 disengaging the ratchet tooth 32 from the pawl 23, freeing the arm 33 to be quickly urged forward by the spring 40. Simultaneously, the lever 35 is pivoted moving its bottom end away from the stop 43,

freeing the sliding member 44 to be slid rearward under the tension of the spring 41, drawing the hook back to the position shown in Fig. 2.

Rearward movement of the hook 5| occurs with the eyelet 51 of the needle 56 still below the base Ill, so that rearward movement of the hook causes its pointed end to pass alongside of the needle 56 and pick-up one side of the loop of thread 36, which loop is formed by the downward movement of the needle 56. v

The needle 56 then continues its upward movement, causing the same to be withdrawn from the layers of cloth material and the pressure foot 6| to be raised to its starting position. The thread 30 is then cut adjacent the needle 56 and the freshly cut end, at the top of the layers of cloth, is gripped and held While removing the layers of cloth from the base Iii, causing the other end of the thread engaged through the layers of cloth, to slide clear of the hook 5|, leaving a strand of thread engaged completely through the layers of cloth as a marker.

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claim.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:
