'MACHINE FOR HOOKING nues AND THE LIKEy Application filed May 19, 1925. Serial No. 31,436.

To all w hom it may concer/n.:

Be it'knovvn that we, JOHN A. BORROWS and CHESLEY T. SABINE, citizens of the United States, and residents, respectively, of

Portland, in the county of Cumberland and State of Maine, and Lewiston, in the county of Androscoggin and'State of Maine,`have invented new and useful Improvements in. a

, Machine for Hooking Rugs and the like,`fof which thefollowing isa specification.

'Our invention relates to a portablemachine employed in the manufacture, principally, of certain kinds ofrugs of which the l5 or other fabric and through which strips of cloth, string or Other pliable material is woven or threaded to form a substantially solid facing on the upper or tread side of the rug.

The especial'object of our invention is to provide 'a device operable by any convenient power means for doing that Work, which in the rug making art is termed hooking, in a rapid, accurate and automatic manner, the operator simplyl keeping the machine supplied with the hooking material and guiding it over the Surface of the sheet of material to be hooked.

Another object is to provide means for varying the length of the stitch, or the distance between the consecutive hookings, so that either a firm or loose facing may be Obtainedv still further obj ect is to con struct a machine with which it is possible toA produce different depths of facings-,so that a thick or thin rug may' result.

And in general,l our object is to 'supply the rug hooking trade'with a portable, easily operated and Strongly built machine in which isincorpo'rated facilities 'for' Operating the power yactuating elements withthe hand, of the operator', which does the guiding ofv the machine', and one which isadaptable to the-use of'av great `variety of material which to do the hooking.' work.v f Other objects Will be apparent in a preferable embodiment of our invention-l is illustrated, 'and in which ally characters. of reference -represent similar parts' s Fig. 1 is a' from-elevationefthe machine',

Fig. 17 shows the machine mounted On the v operating table and in a position as used in the hooking work, and l Fig. 18 shows the slides as they may be equipped with more than one needle and foliower.

Referring to the Figs. 1 and 2, 1 represents the cylindrical portion of the body or frame of the hooker', `9.a bearing extending through the rearward closed end and 3 n cover, attached to the cylinder by the screws 4. Depending 'from the Aunder side of the cylinder is,v a tubular. portion, the outside of which is formed'into the shape of a handle. or .hand-grip 5, andwith the bore, 5', e3 tending therethrough. Y Anotherv ,tubular projection, 6, extends upwardly from the top fixed on the shaft 12. This shaft (12) continues upwardly from the pinion, through the bearing 13, and is journalled at its upper end in the drive-sleeve 14 which has two flanges, 14 and 14, shouldering on the upper and lower ends, respectively, of the split collar 15. This collar (15) is fixed in the bore 6 by the set screws 16, and serves to hold the sleeve 14 against vertical movement within the projection 6, although allowing the former to rotate within the latter at 17 On the lower end of the drive-sleeve (14) is a hub 18, having a key-way 19 cut diametrically across its face. On the upper end of the clutch-ring 20 are keys 21, and these may at certain and predetermined times engage the key-way 19 on' the drivesleeve. At22 is a feather, or travelling key, which is fixed in the clutch-ring 20 and adaptable of length-wise movement in the key-way 23 in the shaft 12.

Projecting from each end of the clutchring 20 are flanges 24, and operating between these and on both sides of the clutchring body is a bifurcated lever 25 oscillatively hung on the pin 26 which is fixed in the ears 27.

A bearing 28 may be provided for taking care of the thrust, in one direction, of the shaft 12.

Fixed on the disc 8 is acrank-pin 29 and operating thereon is the connecting-rod 30. On an extended portion of this pin 29, 29', is fixed a link 31 extending diametrically across the face of the disc and having on its opposite end a crank-pin 32 on which operates the connecting-rod 33,--the disc together with the two crank-pins and the link constituting a double-throw crank.

The lower ends of these connecting-rods, 30 and 33, are oscillatively attac-hed to two slides, 34 and 35, by means of pins 34 and 35', respectively. By reference to Fig. 5 it will be observed that these slides are preferably made rectangular in cross section, the two being adjacent and reciprocable within the square bore of the bushing 36 which is made in halves for the purpose of taking care of the lateral wear between the slides and bushing and also to facilitate and sim- Elify their manufacture. The bushing is eld in place within the hand-grip portion of the body by the screws 37.

Secured in any convenient manner to the lower end of the slide 35 is a needle 38 having a channel 38 formed on its forward side for the purpose of partially enclosing the rag or string used in the hooking operation while the needle is passing through the sheet being hooked, and secured to the lower end of the slide 34 is a follower 39, the lower end, for a spaced distance upwardly, being very thin and flexible and with a considerable inclination toward the needle. A channel 38'? is cut on the rearward side of the needle (38) to receive this follower (39) at certain times during the reciprocation of these two members. An eye 40, through which the hooking material may be reeved, is made on the lower end of the needle which is also slightly inclined inthe direction in which the machine is fed in operating.

Adjustably secured to the rearward side of the hand-grip 5, by means of the screws 41 which operate in the slot-41, is a leg 41 which may be raised or lowered on the handle a certain amount;

Jointedly secured to the lower end of the leg (41) is a presser-foot 42, the two meinbers being locked in any desired angular relation, one with the other, by means of the bolt 42. An opening 43 is cut in the presser-foot through which the needle and follower may operate. The presser-foot is intended, always, to lie fiat on the surface of the rug while the hooker is operating, and any change in the angular relationship between the presser-foot and the leg will result simply, and solely, in a change in the inclination ofI the leg.

In Fig. l5 we have shown a conventional method of attaching a flexible power shaft to the drive-sleeve 14. An adapter 44, to which the casing 45 of the flexible shaft 46 is secured, is threaded on to the upper end of the tubular projection 6. By means of the keyed end 46', of the flexible shaft plug, engaging a key-way 47 in the end of the drive-sleeve 14, the latter may be revolved through the agency of the shaft and any suitable prime move1,-such as the motor shown in Fig. 17.

In -operating the hooker it is very desirable to have instant control over the starting and stopping of the power actuation.

)Ve have provided for this by mounting on the hooker, at a convenient position above the handle 5, a trigger shaped lever 48, pivoting it on the pins 49. This lever (48) is bifureated, and the two branches of the biurcation surround the body of the hooker and extending rearwardly enclose, by a pivoted connection at 51, the lower end of' the connecting-rod 50. This member (50) extends upwardly and makes pivotal connection at 52 with the lever 25. A slot 53, in the connecting-rod 50 allows the latter to surround the bearing 2. A spring 54 normally holds the parts comprising the clutch operating mechanism in the osltion shown in full lines, Fig. 2,--the spring (54) being seated in pockets,-one, 55, in the bearing 2, and the other, 56, in a projection on the connecting-rod 50.

Whenever there is rotatable movement in the flexible shaft 46 the drive-sleeve 14 likewise is under rotation, but as the parts are positioned in Fig. 2 (full lines) no other elements are active. A slight pressure on Cil the trigger 48, however, will lift the clutch@ about to descend to the sheet. As it falls,

the follower rises, so that in Fig. 8l we have illustrated theposition of the parts after one half the cycle of the cranks has been made. On the upward stroke of the needle the rag will loop, as seen in Fig. 9, but justprevious to the complete withdrawal of the needle from the sheet the follower is starting to act to straighten out the loop,-the follower now being on the downward movement,-and by the time the needle has vreached its upward limit of travel the follower will have travelled its limit in the opposite direction and exercised its function as a loop .gauge or straightener, and-thus one full cycle of thecranks is completed and the parts are again returned to the position shown in Fig. 7.

By raising or lowering the leg 41 on the hand-gripl 5 a longer or shorter loop, respectively, will result, due, as will be obvious, to the fact that the needle and follower travel a greater or lesser distance, respectively, beyond the sheet in its downward passage through the same. This adjustability makes it possible to produce rugs of a great variety of thicknesses. n

It is often desirable, and sometimes necessary, to vary the stitch, or the distance between the consecutive loops. This contingency arises' when a lchange of the. maferial with which the rug is to be hooked becomes,imperative,-as when an intricate ligure is to be woven intov the design of the rug', or a more compact or a more loosely laid facing is calledl for. We effect this change of stitch by varying the. angle between the presser-foot 42 and the leg 41. Fig. 10 illustrates the feeding action of the follower when the leg stands at a substantially rightangle to the presser-foot. The full lines represent the follower about to enter the hole previously made by the needle. As it moves downwardly, the rearward side being inclined, the follower will force the presser-foot forwardly, so that at the termination of its full travel the former will have moved the latter to the position shown indot and dash lines, Fig. 10.

of the illustration that the reverse ceding action, or a movement of the presser-foot 'backwardly, might occur when the follower made its upward movement, and thus leave the machine in the position it originally occupied. We have demonstrated that such y1s not the case in actual practice, however. On its downward'movement the resistance of the follower through the sheet tends to lift the machine from the latterand allows it to slide ahead eaSily,-the inclined back of the follower in the perforation effecting the onward feed.` On returning, the same resistance exists but it is now on the forward instead of on the rearward side of the follower and the tendency is to hug or draw the sheet upwardly against the under side of the presser-foot with sufficient force y to overcome to a large extent the recession of the machine on the sheet. Then, too, the needle, entering the sheet in a new perforation somewhat in advance of the complete withdrawal of the follower from the old one, will give the machine a very slight movement ahead, due to the forward inclination of its point, and thus hold the machine from retracting in its feed,-the

follower, meantime flexing as it withdraws.`

If a coarser stitch'is required the body of the hooker is inclined by the adjustment of the bolt 42', so that the angle between the leg 41 and the presser-foot 42 is increased, as seen in Fig. 11,-the two characters a and b representmg the distance' betweenthe stitches in Figs. 10 and.4 11, respectively. In general, it may be said that increasing the angle above referred to lengthens the distance between the -consecutive stitches,-and vice versa.

Althoughrwe have illustrated the machine as a single unit hooker, it is apparent that seweral of these units might be constructed an multiple hooker. Or we may choose to so construct the device that more than one needle and follower may be mounted on each slide, placed ,sideby side, cross-wise laced side by side and operated as a y of the machine and multiply the number of stitches made at each reciprocationl of the Slides, as shown in Fig. 18.
