TWlSTING-HEAD FOR THREAD-DRESSING MACHINES.
SPECIFICATION forming part of Letters Patent N0. 756,487, dated April 5, 1904.
Application filed October 3, 1903.
To all whom it may concern.-
Be it known that I. GEORGE A. FREDEN- BURGH, a citizen of the United States, residing at the city of Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Twisting-Heads for Thread-Dressing Ma-V chines, of which the following is a specification.
My invention relates to a twisting-head adapted for a thread-dressing machine and which twisting-head is driven by a band or cord connection from the whirl-shaft of the same.
The object of my invention is to provide means for stopping the rotative parts of the twisting-head without interfering with the directed movement of its band or cord.
A further object of my invention is to provide means for the ready insertion of a thread to the twisting-head during the operation of the machine.
With these ends in view my invention consists of the novel construction and combination of parts as hereinafter described, and specifically set forth in the claims.
In the accompanying drawings, Figure 1 represents a top plan view of the twistinghead as in operation upon the frame of the machine. Fig. 2 is a side elevation of Fig. 1. Fig. 3 is a partial top plan view of the twisting-head, showing the means for stopping its rotative parts, as when the band or cord moves in a straight direction. Fig. & is a similar view of the twisting-head, showing the means for stopping its rotative parts, as when the band or cord moves in a cross-over direction. Fig. 5 is an inverted view of Fig. 3, and Fig. 6 is a vertical sectional view taken in line X X of the same.
Like letters of reference indicate like parts.
A designates a bracket which has one end secured upon the machine-frame B by bolts 0 c and its opposite or front end portion provided with two circular openings 0 and 0 to receive two stud-shafts (Z and e. Said bracket A is further provided with a narrow slotted opening 0 extending radially from the center of the opening 0 to the front end of the bracket.
Serial No. 175,693. N0 model.)
The stud-shaft d has an integral annular flange cl at its upper end and a spur-gear d rigid upon its lower end thereof. The studshaft 6 has an integral grooved whirl e at its upper end and a spur-gear e rigid upon its lower end thereof. The whirl c has an arm f fixedly secured upon its top surface and projecting outwardly from the same. The gears (Z and e are of equal size and arranged to engage each other without backlash. The studshaft 0Z,-its annular flange d, and its gear al are each provided with a narrow slotted opening 0, extending radially from their axial center, as seen in Figs. 3 and 5, so that a thread 9 may be passed through the slotted opening 0 of the bracket A to a central position in said stud-shaft. A thread-guide it is fixedly secured upon the annular flangeand gear of the stud-shaft d for the purpose of directing the thread to and from the slotted opening in the same.
a is a flexible band or cord connection from thegroove of the whirl e of the stud-shaft e to the driving whirl-shaft (not shown) of the machine-frame. This band or cord 6 drives the rotative parts of my device and can be readily slipped on or off the whirl e to make a change from a straightaway course to a cross-over course, in accordance to whichever Way it is desired todrive the device to put a right-hand or left-hand twist uponthe thread.
A slide-rod j is loosely mounted in extensions a an integral of the bracket A, and thisand with its arm adjoining the side of the inner extension of the same and free of the arm of the revolving whirl 6'. Now if it is desired to stop the rotative parts of the twisting-head the operator will turn the rod j to swing inwardly its arm j into the path of the ICC moving arm of the whirl 6. Thus the rotative parts are stopped instantly and with their slotted openings precisely in alinement with the slot in the bracket, so that a thread may be passed to its geometrical center in the twisting-head, in the manner shown in Fig. 3, after which the arm j is swung free from the arm f of the whirl to allow the rotative parts of the device to be again driven by the constantly-moving band or cord.
is a push-spring mounted in an aperture formed in the bracket A, and said spring is adapted to bear against the surface of the slide-rod j in making frictional contact to hold the same in the position desired upon the twisting-head. When it is necessary to reverse the movement of the device in order to put anopposite-directed twist upon the thread, all that is required on the part of the operator is to slip off the band or cord and replace in a cross position upon the whirl, in the manner indicated by broken lines in Fig. 1, after which the rod 1' is drawn forward until its arm adjoins the outer extension of the bracket A, where the arm remains free of the moving arm f of the whirl 0 until acted upon by the operator to stop the rotative parts, in the manner shown in Fig. 4:, when the slotted openings will be brought in alinement with each other, so that the thread may be tied and again replaced in the twisting-head.
By this construction and arrangement of parts I form a device that contains in itself all that is necessary to afford a quick means of putting a right-hand or left-hand twistupon the thread, as the occasion requires, and at the same time, being compact, allows of a large number of twisting-heads to be mounted on the machine and each operated upon independent of the other.
This invention is an improvement upon the thread-dressing machine shown and described in Letters Patent of the United States No. 7 02,7 86, issued to me June 17 1902.
Having described my invention, what I claim, and desire to secure by Letters Patent, 1s
1. In a twisting-head for a thread-dressing machine, having a whirl-shaft driven by power thereon, the combination of a fixed bracket provided with 'a slotted opening in its front portion and two integral side extensions; a stud-shaft mounted in said bracket and having an integral annular flange at one end and a spur-gear rigid at its opposite end thereof, and said stud-shaft, its flange and gear provided with a radial slotted opening arranged to meet in alinement with the slotted opening in said bracket; thread-guides fixed upon the flange and gear of said stud-shaft, to direct the thread to and from the slotted 'opening in the same; a second stud-shaft mounted in said bracket and having an integral grooved whirl at one end and a spur-gear rigid at its opposite end thereof to engage the gear of the first-mentioned stud-shaft; a band or cord connection from the whirl of second-mentioned stud-shaft to the whirl-shaft of the machine; an arm fixed upon the whirl of secondmentioned stud-shaft; a slide-rod mounted in the extensions of said bracket and having a rigid arm arranged to swing into the path of the arm of the whirl of second-mentioned stud-shaft; and means to hold said slide-rod in the position desired upon said bracket, substantially as set forth.
2. In atwisting-head for a thread-dressing machine, having a whirl-shaft driven by power thereon, the combination of a fixed bracket provided with a slot in its front portion and two integral side extensions; a stud-shaft mounted in said bracket and provided witha radial slot; a gear rigid upon said stud-shaft and provided with a radial slot; a threadguide fixed upon said stud-shaft and said gear; a second stud-shaft mounted in said bracket and having an integral whirl provided with a groove; a gear rigid upon said second-mentioned stud-shaft to engage the first said gear; a projecting arm fixed upon the whirl of said second-mentioned stud-shaft; a band or cord connection from the whirl of second-mentioned stud-shaft to the whirl-shaft of the machine; a slide-rod mounted in said bracket, and carrying a rigid projecting arm which has freedom of movement between the extensions thereof, and so arranged that the said rod may be moved to swing its arm in the path of either rotative direction of the firstmentioned arm, whereby the slotted openings of the said parts are brought in alinement with each other, substantially as shown and for the purpose specified.
