12 Claims. 1

This invention relates to a method and drill for marking fabric, and more particularly for marking a pile of many layers of cloth by drilling small holes through the cloth and simultaneously applying color at the edges of the drill holes, and the object of the invention is to provide a method in which the drilling and simultaneously the application of color can be obtained rapidly and with security.

A further object of the invention is to provide a device for drilling holes and simultaneously applying color which is simple in construction and reliable inoperation.

Still a further object of the invention is to provide an improved marking drill adapted to use powder or chalk, in which a uniform supply of powder or chalk can be fed to a pile of cloth. A special object in this connection is to provide a marking drill in which the powder is fed forward Without damage or clogging in the feed channel.

Further objects and advantages according to the invention will appear from the following specification and the appended claims.

Reference will now be had to the accompanying drawing, in which Figure 1 is a sectional elevation of a machine in accordance with the invention,

Figure 2 is a vertical section taken on line 2-2 in Fig. 1,

Figure 3 is a side elevation of one end of the machine showing a specialstarting device,

Figure 4 is a sectional view showing another form of the starting device, and

Figure 5 is an elevation showing on an enlarged scale the tip of the needle and a small portion of the receptacle for the pigment.

In the drawing, I is a base plate forming a support for the textiles to be marked out.- A bracket 2 is secured to the base plate near one end thereof and extends over the base plate from one end thereof adjacent to and above the opposed end thereof. A vertical hollow shaft 3 is mounted in ball-

bearings

4 and 5 at the free end of the bracket 2 and has a belt pulley I secured thereto as by means of a set-screw 6, Fig. 2. An electric motor 8 having a belt pulley 9 is mounted on the base plate I'- within the foot of the bracket 2, and is connected with the belt pulley I by means of a. driving belt I0 which, in the form shown, runs over guiding r idler pulleys I I.

A spindle I2 is slidable axially, in the hollow shaft 3, and is held against rotation relatively to the shaft'3 by a keyway I3 which is engaged by a key disposed within the shaft 3 so as to prevent relative rotation of the spindle and the shaft but permitting a relative sliding movement thereof. The spindle I2 carries near its lower end a ball-bearing I5, the outer ring of which is slidably guided in a tube It extending in a vertical downward direction from the arm 2. Two laterally extending pins I! are secured to the outer ring of the ball-bearing I5. The pins I 'I engage vertical slots I8 in the tube I 6 and are connected with a yoke-shaped portion I9 of a hand-lever mounted for vertical pivoting movement on the bracket 2. To permit the lever portion I9 t follow the linear movement of the pins I! which, as stated above, are guided in the slots I8, the pivot 2| of the lever 20 is mounted for substantially horizontal sliding movement in slots 22 in the bracket 2. A needle 23 is screwed into the lower end of the spindle I2 in axial alignment therewith, thus mounted for vertical sliding movement relatively to the base plate I.

Another tube 24 telescoping on the tube It is provided with vertical slots 25 through which the pins I! extend and by means of which said tube 24 is supported upon said pins in inoperative position shown in the drawing. The tube 24 is at its lower end provided with an end plate 26, and between this end plate and the outer ring of the ball-bearing I5 a helical compression spring 2'! is inserted. The end plate 26 is provided with an aperture 21a through which the needle 23 extends. A casing 28 is by means of a screw-threaded socket 29 screwed to the lower end of the tube 24 in axial alignment therewith. The casing is provided with a top plate 30 having an aperture through which the needle 23 extends. Another aperture for the needle is provided at the bottom of the casing. This aperture forms a sliding or running fit with the needle 23 so that the latter will close the aperture. As shown in the drawing, th length of the needle 23 is such that the lower end of the needle will just close the bottom aperture of the receptacle 28 in the inoperative position shown in the drawing.

The casing 28 encloses a chamber adapted to receive a pulverulentpigment, which preferably consists of a dry powder or chalk and which is intended to be introduced into the textiles to be marked out by means of the needle 23.

In use a plurality of layers of textiles to be marked out are supported on the base plate I, if desired together with a templet, according to which the marking out is to be efiected. After the motor 8 has been started, the hand-lever I9,

3 2B is manually depressed, whereby the needle 23 as well as the tube 24 with the casing 28 secured thereto are lowered towards the textiles while the needle rotates.

When the bottom of the casing 28 engages the upper textile layer, the casing and the tube 24 are stopped. The spindle l2 with the needle 23 are however urged further downwards by means of the hand-lever I9, 23 and against the action of the spring 21 so that the needle 23 penetrates the several layers of textiles. As shown in Fig. 5, the needle is provided with a helical surface groove through which the pigment contained in the receptacle 28 can flow along the needle and dispose itself on the textile around the holes made by means of the needle.

The direction of the helical groove 3| is chosen in such a manner relative to the direction of rotation of the shaft 3 and the needle 23 that the groove tends to expel the pigment from the receptacle 28 through the bottom aperture thereof somewhat in the manner of a screw conveyor. As indicated by an arrow 32 in Fig. 5, it is assumed that the shaft 3 rotates in a clockwise direction as seen from above. In accordance herewith the groove 31 extends in a counterclockwise direction as shown in Fig. 5. Hereby suflicient pigment is fed from the chamber through the groove of the neeedle to all of the layers of textile supported on the base plate I.

In order to prevent the tip of the needle 23 from being damaged through contact with the base plate I, the latter is provided with an aperture 33 situated in axial alignment with the needle 23. A small receptacle 35 is provided immediately below the aperture 33 for receiving excessive pigment, if any. Downward movement of the needle 23 is limited by the pin l'i abutting against the lower end of the slots iii of the tube It so as to ensure penetration of the lowermost i layer of textile by the needle but preventing the needle from making contact with the bottom of the receptacle 34.

When used for marking out large pieces of textile, the machine may conveniently be portable so that it can be moved along the textile as the marking out proceeds. To this end, the base plate 1 is preferably relatively thin and bevelled at its edges as shown in Figs. 1 and 2 so that it can easily be introduced under a pile of textiles disposed upon a table. In order to facilitate introduction of the base plate under the textiles the base plate is provided with small rollers 35.

In Fig. 3, a small push-button switch 36 is secured to the casing 23 and has its push-button 3'! extending vertically a small distance below the level of the bottom of the casing 28. The switch 35 is connected with the motor 3 by means of a cable 38. When the casing 23 and the needle 23 are lowered towards the upper side of a pile of textiles by means of the lever I9, 20, the pushbutton 31 will engage the upper side of the pile so as to be actuated during further downward movement of the casing 28. The switch 36 will thereby close the circuit of the motor 8 so as to start the same. When the push-button is again disengaged from the textiles the motor stops.

In the form shown in Fig. 4, a push-button switch 39 is secured to the lever I9, 20, and its push-button it) is adapted to co-operate with one arm of a two-armed lever ll mounted in the yoke I9 and carrying a roller 42 on its other arm. The lever 4| is carried by a torsional spring d3 which tends to urge the lever 41 to press the push-button but is prevented therefrom by the roller 52 engaging the shoulder on the tube It. When the lever I9, 20 is manually depressed against the action of a spring (not shown) the roller 42 will be disengaged from the shoulder of the tube I6 so as to permit the torsional spring 43 to actuate the push-button 40 so as to close the circuit of the driving motor of the machine.

The invention is not limited to the specific embodiments described and shown in the drawing, which may be varied and modified in several respects within the scope of the appended claims.
