A PETERSEN BOBBIN STAND FOR BRAIDING MACHINES Filed Aug. 16. 1922 Patented ct. 3Q, 1923.
lbtihdt ANKER PETERSEN, OF WIN'IHBOP, MASSACHUSETTS.
BOBBIE STAND FOR BBAIDIHG MACHINES.
Application filed. August 18, 1922. Serial No. 582,164.
To all whom it may concern:
Be it known that I, ANKER PETERSEN, a citizen of the United States of America, and resident of Winthrop, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Bobbin Stands for Braiding Machines, of which the following is a specification.
.This invention concerns braiding machines of that type wherein two series of bobbins are caused to revolve in opposite directions about a common center and having means for causing the threads from the outer series of bobbins to pass alternately over and under successive bobbins of the other series,
and relates more particularly to an improved stand or support for the bobbins of the outer series.
The object of the present invention is to simplify the construction of braiding machines of the above type by reducing the number of parts employed, thus decreasing the weight and air resistance of the revolving mass, and more specifically to provide an improved type of bobbin stand for supportin bobbins of the outer series, each stand having bearings for adjacent bobbin spindles so as to decrease by one-half the number of brackets usually employed.
In the drawings there is illustrated by way of example a preferred form of bobbin stand embodying the present invention and in such drawings,-
Fig. 1 is a fragmentary plan view of a braiding machine of the type above referred to, showing the device of the present invention applied thereto;
Fig. 2 is a fragmentary side elevation of the machine shown in Fig. 1;
Fig. 3 is an inside elevation of one of the bobbin stands forming the subject matter of the present invention;
Fig. 4 is a side elevation of such bobbin stand; and
Fig. 5 is a horizontal cross section on the line 5-5 of Fig. 3.
Referring to the drawings, the circular frame of a braiding machine is indicated at 1 while the numeral 2 designates the rotating support upon which the outer series of bobbins 3, 3 etc. is mounted. A stationary support or track 4 is arranged concentric with the support 2 and serves to guide and support the inner series of bobbin carriers 5, 5 etc. provided with the bobbins or spools 6, 6 respectively. The yarns or threads from these latter bobbins pass through suitable guides to the center of the machine for interbraiding with the threads or yarns from the outer series of bobbins or spools. The threads from the outer series pass through guide members 7 fixed to the support 2 and through guide eyes in movable detector fingers 8 and thence to the warp levers 9 by means of which they are caused alternately to pass above and below the bobbins of theinner series all in a manner well known in the art.
In accordance with the present invention, the bobbins or spools of the outer series are supported upon bobbin stands each of which comprises a base member 10 having openings '11 for the reception of screws or bolts by means of which the base member may be secured to the rotating support 2. A post 12 rises from the base member preferably having an inwardly extending and substantially radial rib 13. From opposite sides of this rib at the upper part of the post, flange members 14, 15 project, which serve to define outwardly inclined slots or pockets 16,
17 respectively, open at their upper ends and provided with flaring guide mouths 18, if desired. The lower ends of these slots terminate in curved walls 19, 20 respectively, constituting bearings for the ends of bobbin spindles as hereinafter described. As indicated in Figures 3 and 5, the bearings 19, 20 lie in substantially the same horizontal plane but have their axes disposed angularly with respect to each other.
A pair of lugs 21, 22 project outwardly from the outer edge of the base 10, being provided with bearing openings 23, 24 respectively, arranged in the same horizontal plane but having their axes substantially parallel respectively to the axes of the bearings 19, 20. A second pair of lugs 25, 26 project from the inner edge of the base 10, the% lugs having bearing openings 27, 28 lying in the same horizontal plane but with their axes parallel respectively to the axes of the bearings 19, 20. A lug 29 projects from the central portion of the base in an inward direction and has a bearing opening 3 whose axis is substantially parallel to that if the bearing 19. A screw threaded opening 31 intersects the bearing opening 30 substantially at right angles thereto.
As indicated in Figure 2, the adjacent ends 32, 33 of the spindles of neighboring bobbins 3 3 respectively are seated within.
the bearings 19, 20 formed by the lower ends of the pockets 16, 17. The opposite ends of the spindles 32, 33 are similarly positioned in bearings formed in the next adjacent bobbin stands to the right and left of the post 12 respectively, it being understood that these bobbin stands are similar in all respects to that shown in Figs. 3 to 5. Ad-
away from the support 2 in opposition to the sprlngs but when the yarn breaks the shafts 34, 34 rotate under the action of the springs 35 and complete an electrical circu1t in well known manner for stopping the machine.
The bearings 27, 28 support adjacent ends of exhaust detector shafts 35 35 having detector fingers 36, 36 secured thereto. These shafts normally tend to rotate under the action of springs 37, 37 respectively 111 such manner as to hold their detector fingers in contact with the yarn mass upon the spools 3, 3 etc. When the yarn mass is exhausted the detector fingers move inwardly, completing an electrical circuit in own manner for stopping the machine. A shaft 38 is secured in the bearing openmg 30 by means of a setscrew 39, and this shaft supports a bobbin tension device 40 comprising a series of resilient fingerswhich bear against the outer surface of the thread mass to retard the rotation of the latter, thus tensioning theyarn.
'l[he bobbin stand herein described pro vides all the necessary bearings for adjacent ends of the spindles of neighboring bobbins, as well as the detector means assoc ated therewith and each stand also prov des means for supporting the bobbin tens1on device for one bobbin; By the employment of this bobbin stand, it is possible to dispense with one-half the number of stands customarily employed, thus decreasing the weight and air resistance of the rotating pa rts while at the same time cutting down the cost of construction and giving the machine a more pleasing appearance.
While ag herein disclosed the bobbin stand is provided with supporting elements for the bobbins and certain associated parts, it is contemplated that someof these elements might be dispensed with under certain circumstances or that other and additional supporting means might be provided if occasion should so demand.
What I claim and desire to secure by Letters Patent of the United States is:
