HERMAN JONSON, OF NEW YiORK, N. Y., ASSIGNOR, BY MESNE ASSIGNMENTS, TO MANTLE MACHINERY AND PATENTS COMPANY, A. CORPORATION 0F NEW YORK.

MACHINE FOR INSERTING PUCKER-CORDS IN TUBULAR STRUCTURES.

To all whom it may concern:

Be it known that I, HERMAN JoNsoN, a citizen of the United States, and resident of the borough of Manhattan, in the city and State of New York, have invented a new and useful Improvement in Machines for Inserting er-Cords in Tubular Structures, of which the following is a specifical tion.

My invention relates to a machine for inserting a pucker cord in a tubular structure.

The object is to provide for consecutively forming the gathers in advanceof the needles, relying' upon the needles to hold the puckers in position and in connection therewith to provide convenient means for threading the needles after they have been advanced through the gathers or folds.

In the accompanying drawings, Figure 1 is a view of the machine in side elevation showing the needles withdrawn for the recept-ion of the structure to be operated upon, Fig. 2 is a transverse section in the plane of the line A-A, Fig. 1, looking toward the left as the drawing is held, Fig. 3 is a transverse section in the plane of the line B-B, Fig. 1, Fig. 4 is a top plan view showing' the parts in the position which they assume when the needles are withdrawn for the reception of the tubular structure to be operated upon, Fig. 5 is a similar view showing the position of the parts when the needles have been advanced through the folds of the structure with the threading devices in position to receive the thread, and with the guide block removed, Fig. 6 is a similar view showing the position of the parts after the needles have traveled a short distance on their return movement, and with the guide block removed, and Figs. 7 and 8 show the bell crank lever "for operating the threading device in elevation and plan respectively.

The machine frame comprises a base 1 from which

posts

2, 3 and 4, 5 uprise for the reception of a pair of ways in the present instance a pair of round bars 6 and 7. On these bars the operating mechanism is arranged to slide as follows. A pair of sleeves 8 and 9 are fitted to slide on the rods 6 and 7 respectively and these sleeves are connected at their outer ends by a yoke or cross-beam 10 to which the needles 11 and 12 are fixed by means of a clamp plate 13 made Specification of Letters Patent.

respectively by 16 and 17. The sleeves 8 and 9 with their needle supporting and

sector supporting yokes

10 and 15 constitute a sliding carriage which may be operated by means of a rod 18 connected with a suitable source of power, not shown, or it may be moved by hand.

Centrally between the ways 6 and 7 and in advance of the needles 11 and 12, there is mounted a plate o-r table 19 supported by a series of posts 20 on a beam or plate 21 xed to and supported on the base 1. The series of posts 2() is located midway between the toothed sectors 16 and 17 and forms in effect a rack bar common to the two so'that when the carriage is advanced, the engagement of the teeth on the sectors 16, 17, with the posts 20 will cause the two sectors to rotate o-n their axes, bringing their teeth consecutively between the posts 20. Above the posts 420, there is mounted a center member or guide block 22, preferably pearshaped in cross section as shown and vertically corrugated and -supported by a series of pins 23 forming extensions of the axes of the posts 20. On opposite sides of the central line of the table 19, there is located a series of pins, the series on one side being denoted by 24 and the series on the opposite side by 25. These pins are set fast in the` table 19 and extend upwardly therefrom, stopping a short distance below the guide block 22. The needles 11, 12 are so spaced with respect to the series of

pins

24, 25, that they will, when they advance, follow along in proximity to the inner faces of the series of

pins

24, 25, as clearly shown in Figs. 5 and 6.

For the purpose lof conveniently threading the needles after they have been passed through the folds in the structure to be operated upon, I provide `each of the toothed sectors with a longitudinally sliding threading device consisting of a bar having its head toward the needles flattened suiiciently to pass through the eye of the needle and provided with a perforation extending vertically therethrough. These threading devices carried by the toothed sectors are denoted respectively by 26, 27, The head 28 of the threading device 27 is conveniently offset so that it may pass the head 29 on the said threading device 26 as they pass through the eyes of the needles into the position shown in Fig. 5. 'Ihese longitudinally sliding threading devices are operated by means of bell crank levers 30, 31, pivotally secured to their respective sectors with their

short arms

32, 33, connected with the sliding threading devices and their

long arms

34, 35, in position to engage

pins

36, 37, fixed on supports 3S, 39, made fast to the base to tilt the lever, throwing the threading devices inwardly through the eyes of the needles as the needles approach the limit of their advance movement and during the early part of the return movement of the needles, these long arms will engage their

pins

40, 41, to tiltthem back into the position to withdraw the threading devices from the eyes of the needles. In this withdrawn position these bell crank levers will be frictionally held by means ofv friction springs 42, 43, made fast at one end to the supports for the sector wheels and their opposite ends provided with

bent noses

44, 45, to engage depressions 46, 47, in the faces of the long arms of the bell crank levers.

The table 19 may be conveniently provided with a post 48 located in position to receive the bite of the thread as it is drawn by the needles through the several folds to prevent it from becoming displaced. In Figs.v 5 and 6, the tubular structure to be operated upon is denoted by the line 49 and the puclrer cord or thread is denoted by 50. The table 19 is further provided with two recesses 51, 52,i arranged to receive the points of the

needles

1,1, 12, as they near the limit of their forward movement so that the needles are centered and held against lateral movement while the threading device is` operated.y It will be understood that the needles 11, 12, pass through recesses 53, 54, in the faces` of the teeth of the sectors 16, 17.

In operation,` assuming t-he parts to be in the position shown in Fig. 4, the mouth of the tubular structure to be operated upon may be slid down over the guide block 22 and over the series of

pins

24, 25, until it rests in engagement with the top of the table 19. The carriage carrying the needles and sector wheels is then advanced, 'the teeth on the sector wheels gathering the mouth of the tubular structure into folds indicated by the line 4,9., these folds being formed consecutivelyl immediately in advance of the pointsof the needles and the needles themselves passing through the folds one after another as they are formed by the teeth. As the sector wheels reach the limit of their movement, the needles project beyond the tubular structure and at this mo-. ment the angle levers are locked and the threading devices are passed through the eyes of the needles into the posit-ion shown in Fig. 5. The operator now passes the ends of the thread 50 through the eyes in the threading devices and the carriage is given the reverse or return movement- The early part of this movement rocks the angle levers, withdrawing the threading devices from the needles and by so doing, drawing the ends of the threadthrough the eyes of the needles. The further return movement of the carriage will draw the thread successively through the several folds or gathers and finally the free ends of the threads will be withdrawn from the eyes of the needles and the tubular device with its puclrer cordy in place may be removed from the guide block, its gathers 'passing up over the series of

pins

24, 25, between the guide block and the tops of the pins.
