specification of Lettera Patent.

Application filed November as, 1912. Berial No. mazes.

of my invention is to provide effective machine for this purose, of great capacity, and accurate in its work, having in regard, particularly, the nature of bunting and the uses to which it end my invention conmachine which I shall now fully describe by reference to the ac; companying drawings, in which- Figure 1 is a plan of my invention. Fig. 2 is a vertical section on line l y of. Fig. l.

1 is a stand or table from which rise the end plates 2 which carry the several parts of the'machine. Suitable tie rods 3 hold and stiffen the end plates.

In the front of the machine is one of the feed reels consisting of a shaft 4 to revolve between the end plates 2. The means for mounting this shaft 4 are designed to permit its free revolution and to allow it to be removed and to be replaced with facility. These means comprise a chuck shaft 5 mounted to revolve in a hearing 6 in one end plate 2, said shaft having a clutch tongue 7 detachably engaging a groove 8 in one end of the reel-shaft l; and a tail-stock shaft 9 With pointed end revolubly supporting said reel-shaft at its shaft being slidbearing 10 in the other end plate 2, and held in to its work by a 11 housed in a sleeve 12. A handle 13 on the outer end of the tail-stock shaft enables it to be drawn back sufficiently to release the reel-shaft 4; when desired. It may be stated at this point that all the other reel and spool-shafts in the machine are sists in the novel similarly mounted; in view of which these I rods is a triple guide mounted partsneednot again be specifically described, though for the sake of clearness they are designated by the same numerals in so far as they appear in the drawings.

14 is a second feed-reel, a little above and back of the first feed-reel 4.

In the lower front of the machine is a guide rod 15. In the upper front of the machine is a. guide rod 16 mounted in the end plates 2.. Immediately back of and parallel with the guide-rod 16 and in a slightly lower plane is another similarly mounted guide-rod 17 separated from the first by a slight space and constituting with said first the front pair of guides. Slidably mounted upon the guide-rod 16 are the edge-guides 18 for the edges of the cloth. These are fitted with set screws 19 in their hubs, to fix themin whatever position they are set. These guides 18 are here shown as disks,

and by being slotted, as indicated at 18,

upon the adjacent rod 17 of the front pair oi" guide rods, they serve the further purpose of holding and stiffening the rods in their parallelism. Beyond and in a little higher plane than the front pair of guide compris ng a rod 20, another rod 21 somewhat higher and farther bark, and a third rod 22 still farther back and slightly lower than the rod 21. These" are spaced apart and parallel and are carrind by and between the end plates 2. Edge guides 23 similar to those 18 heretofore described, are adjustably mounted on the guide rod 20. I

Carried by and between the end plates 2 is the lmifc-holdcr bar 24, detachably held by a thumb-screw 25 at one end. Upon this bar are slidahly fitted the knife-holders 26 fitted with set-screws 27 by which their position can be defined and regulated. These holders carry the knifc-blades 27, and these latter lie in a plane between the front guide rod pair and the triple guide, and they intersect the path of the cloth-from the former to the latter guides. Secured to the end lates 2 is a spreader 28. This lies be yon' the front pair of guide rods, but in advance of the knives. It consists of a. smooth dull edged plate or bar and is so Patented Apr. 22, 1913.

located that the cloth from one feed-reel passes under it and the cloth from the other feed reel passes over it so that the two cloths are directed and presented to the knives in a separated or spaced relation.

At the back of the machine, carried by and between the end plates 2 are the strip-re ceiving spools. -There may be two or more of these; three are here shown. Each comprises a shaft and end flanges or heads mounted adjustably on the shaft. One shaft 29 is mounted in theupper portion of the and plates another 30 is similarly mounted in the lower portion of said plates, and the :third 31 is mounted between the other two,

so that said spools lie in different horizontal planes, in vertical series. The end flanges or heads 32 are slidable on their shafts and each is fitted with a thumb screw 33' to establish its position as desired. The clutch shaft 5 of the middlespool-shaft 31 is fitted with a drive pulley 33 on its outerend. Said shaft has also a -year 34 which above meshes with a gear 35.01: the clutch shaft 5 of the upper spool-shaft 29 and below with a gear '36 on the clutch shaft 5 of the lower spoolshaft 30. Thus the strip receiving spools are driven in unison. a

In order to impose upon the feed-reels, a tensionor pressure sufficient to retard and equalize their revolutio'nas the cloth is'unwound or paid out from them, I have a spring 37 in a bracket 38'mounted on one of the end plates 2. This spring bears upon the clutch shaft 5 and is held thereto with regulatable pressure by a thumb screw 39. There is one of these tension devices for each I feed-reel.

The operation is as follows :-It will he noted that the machine as illustrated is fitted for two separate rolls of hunting. One of these 4.0 is carried by the first fced-reel 4: and the other 41 by the second feed-reel 14. The, particular purpose of this double feature is notmcrely to double the capacity of the machine but to enable it to cut simultaneously into strips two rolls of bunting one of one color and the other of another color, which is particularly of advantage in the manufacture of flags, a use to which hunting is most commonly put. Let us say one of the rolls is white and the other red, as applicable to the U. S. flag, and consider that the white roll 40 is on the first reel 4: and that the redroll 4-1 is on the second reel 14:. Now tracingby reference to Fig. 2, the

1 course of the cloth of the white roll 10,'it

will be seen that it extends from its reel 41 to the guide rod 15, and over said rod to and in contact with the upper surface of the higher guide rod'16 of the front pair of guides, its edges being accurately guided by the edge guides 18 on said rod. Thence it passes upon arid over the upper surface of the spreader 28, and thence to the knifeblades 27 which intersect its path and cut it.

into strips, here shown as three strips.

Thence these three strips pass to and between the

rods

21 and 22 of the triple guide, beingguided thereto by the edge-guides 23 on the rod 20. The strips pass thence one to the upper receiving spool 29, a second to the middle receiving spool 31, and the third to the lower receiving spool 30. Tracing now the course of the cloth of the red roll 41,

it passes from its reel 14 to and betweenthc guide

rods

16 and 17 of the front pair, lying in contact with the upper surface of the lower one 17 of the-pair;. its edges being guided by'the edge-guides 18. passes under the spreader 28 and thence past the knife-blades '27 which cut it into three strips. Thence these strips pass over the rod 20.01 the, triple guide, and thence they are carried each to the same receiving spool to which the corresponding overlying white strip was carried, so t at upon each receiving spool -is wound a w: itestripand a red strip, of corresponding size rand adapted when taken together to the sewing machine to be easily and accurately sewed together. In this operation it will be noted that the two cloths and their strips fare kept out of'contact throughout, until they wind together upon the receivin spools. This is of great advantage in handling fugitive ma- Thence it terial like bunting. It prevents crawling which is sure to result fromcontact, and enables each cloth to be separately and accurately guided with such precision that the knife-blades will follow a single thread and not cross it, thereby avoiding the tendency of the strip to stretch stretching being sure to result from anythingbut an absolutely straight out, such an untrue cut, for example, as follows the attempt to cut bunting by hand. ,The' several adjustments of the edge guides and of the knives provide for this accuracy of operation and also determine the width of the strips, while thd number of the knives determine the number of strips v into which the cloth is cut.

The advantage of mounting the several receiving spools in different horizontal posi tions is not only to insure the independence of the strips without further guidance, bu'talso by spreading them out behind the cutof details, such as may occur to those skilled in the art, may be made without afi'ecting the principle and operation of the machine.
