Description
Patented pr. 20, 192th.
U N l it all ANKER PETERSEN, OF VINIHROP, .MASSACHUSETTS BRADNG MACHNE.
Application led Sept( mbe-r 17'0 all 'Lo/0m it may concern.'
Be it known that l, Annan Pn'rnnsnn, a itizen 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 Braiding l/lachines, of which the following is a specification.
This invention pertains to braiding inachines of that type in which two series of bobbin carriers are caused to revolve in opposite directions to intertwine their yarns at a centrally disposed braiding point, and relates more particularly to means for driving the bobbin carriers of the inner series.
In my Patent No. 1,413,931 dated April 25, 1922, I have disclosed an arrangement for driving` the carriers of the inne series comprising a propelling or pusher roll which is rotated by the frictional engagement of an associated felt roll or washer with a resiliently supported leather ring.
The object of the present invention is to provide improved means for rotating the pusher roll with greater uniformity of action and with substantial freedom from slippage even at extremely high speeds but without sacrificing the simplicity and lightness of weight attainable by the patented structure.
ln the accompanying drawings vone preferred embodiment of the invention is illustrated by way of example;
Fig. l being a fragmentary vertical section through a braiding machine of well known type having the present improvements embodied therein;
Fig. 2 is a plan view of a table or stationary support forming one feature of the invention, and
Fig. 3 is a side elevation to larger scale showing a carrier driving roll together with its actuating pinion and shaft.
Referring to the drawings the frame of the machine is indicated at 1. This frame supports a stationary vertical hollow shaft 2 upon which the sleeve 3 is mounted to turn. The shaft 2 is secured in any suitable manner as by means of a set screw 2"l engaging a threaded opening in the frame and bearing against the shaft.
rl`he lower end of the sleeve 3 is preferably mounted on anti-friction bearings and is furnished with a disk-like plate 4. which is keyed to the sleeve at 5. ein annular beveled gear 6 is secured to the beveled edge Serial No. 665,705.
of the plate 4 and meshes with a pinion 7 fixed to a main drive shaft 8. The shaft 8 is provided with fast and loose pulleys 9 and 10 respectively and may be driven by a belt from an*7 suitable source of power.
A second sleeve 11 surrounds the sleeve 3 about the plate 4, being supported to turn relatively to the sleeve 3 by suitable antifriction bearings. The sleeve 11 supports a spider 12 which in turn carries an annular beveled gear 13 which also meshes with the pinion 7. The arrangement of the gears 7 and 13 and the pinion 7 is such that the gears turn in opposite directions. The spider 12 is extended outwardly and upwardly to form the outer revolving frame 1li upon which the bobbin carriers (not shown) of the outer series are mounted in the usual manner.
An inner, carrier driving frame 15 is keyed to the upper end of the sleeve 3 at the point 15a. Upon the outer edge of this inner frame a series of brackets 16 is mounted, only one of these brackets being illustrated, it being understood that the other brackets are of substantially the saine construction. Each bracket 16 comprises spaced bearings 17 and 18 in which a shaft 19 is mounted. The shaft 19 is substantially radial with respect to the axis of the sleeve 3 and preferably inclines downwardly and outwardly substantially as illustrated.
Above the disk 15 an open spider-like frame or table 2O is mounted. This table has a hub 21 which is keyed to the upper end of the stationary shaft 2 at the point 22 and is furnished with an annular guide track 23 upon its upper side and with an annular gear 2li upon its lower side adjacent to its peripheral edge. The outer or peripheral portion of the table 20 is as shown arranged in outwardly diverging relation to the shafts 19 so that at their outer ends these shafts are spaced further from the under side of the table than at their inner ends.
rlhe outer revolving frame 1d is furnished in the usual manner with an internal groove 14a having a substantially iiat lower surface 1lib upon which the outer supporting wheels 25 of the bobbin carriers 26 are supported. These bobbin carriers 26 of the inner series are also furnished with supporting wheels or rolls 27 at their inner ends, the latter wheels or rolls resting upon and travelling along the track 23 carried by the table 20,
A pusher-roll 2S is secured to the outer end of the shaft 19v off each of the brackets 16. T he shafts 19 project outwardly beyond the edge of the table 20 which overlies the brackets 16 and the rolls 28 are of a diameter such that they project upwardly beyond the edge ot the table. These rolls are preferably formed of telt or some similar material and engage rolls 29 carried by the respective bobbin carriers 26.
A pinion 30 is associated with the pusherroll 28 ot' bracket 16, being connected to the roll in any desired manner to rotate therewith. Pinions 8O are ot smaller diameter than the rolls 28 and mesh with the gear 24 on the under side ot the table 20.
lVhen the main drive shaft 8 is rotated the sleeves 3 and 1l turn in opposite, directions, thus causing the outer traine l-l to turn oppositely to the inner frame 15 upon which the brackets 16 are mounted. The carriers 26 of the inner series vare iree to travel along the concentric tracks lll and 23 and as the Vcompels the pusher rol-ls 28 to rotate at a speed exactly in accordance with the speed at which the inner frame is driven. Slippage between the surfaces of the pusher roll 2S and the roll 29 is thus reduced to a minimum with consequent gain in efficiency and substantial elimination of yarn breakage.
The desired result is thus attained without substantially complicating the mechanism and without unduly increasing' the weight of the parts which is highly important in machines of this character which are commonly run at speeds of the order of 3000 R. P. M.
l claim:
A braiding machine comprising an outer frame provided with an annular carrier supporting track, an inner frame, means for turningsaid trames in opposite directions about a common axis, a lixed disc-like table overlying the inner frame and having an annular carrier supporting track concentric with the track of the other trame, a carrier havinov anti-friction means envaaine' the re- Z': D o
spective tracks, a rotary shaft below the table, said shaft being supported by the inner rotating' frame and extending radially outward and downward with its axis intersecting the plane of the table substantially at the center oit the latter, a pusher-roll mounted upcn the shaft adjacent to the outer end of the lat-ter and engageable with an elen'ient ot' the carrier to propel it along its supporting tracks, a pinion co-axial with the pusherroll and disposed closely adjacent to the inner side of the latter and connected to the pusher-roll, the pinion being less in diameter than the roll and underlying the peripheral edge portion ol the table, and an annular gear secured to the under side of the table and meshing with the 4pinion whereby te rotate the latter and the pusher-roll about the axis of the pusher-roll shaft when the inner frame turns relatively tothe table.
