i WITNESS INVENTOR WM y Patented Jan. 21, 1930 UNITED STATES PATENT @FME GRANT SIPP, OF PATERSON, NEW JERSEY, ASSIGNOR TO SIPP EASTWOOD CORPORA- TION, OF PATERSON, NEW JERSEY, A CORPCRATION 0F NEW JERSEY QUILLING MACHINE Application filed December The present invention relates to winding apparatus and especially winding apparatus of the type known as quilling machines. The invention has in View toV reduce the cost of manufacture of apparatus of this class, to facilitate the assembling and disassembling thereof, to make it better adapted to withstand the wear and tear incident to its use and supervision at the hands of perhaps in differently skilled operatives, and to increase the efficiency thereof in general.

The novel features of the invention will be hereinafter pointed out and finally embodied in the clauses of the claim.

F ig. 17 is a side elevation thereof from another angle.

1 is a suitable elongated housing` open only at the top (except where certain parts to be indicated protrude) and having a removable cover 2 partially shown by dotted lines in Fig. 2, also see Fig'. 3. It may have all around a trough-like flange or lip 3 to catch such oil as may werk its way from the housing. At each long side the housing has an interior ledge 4 or equivalent on which a part of the mechanism contained in the housing is seated, the ledge in the present case appearing interrupted. The bottom of the housing has upstanding therefrom a continuous wall 5 forming (Fig. 3) an elongated well G open at the top but at both sides of this well a receiver is formed, as at 7 (Fig. 2) whose bottom slopes toward one end of the housing, where it is suddenly depressed, as at 8. The well 6 is kept supplied with oil as I shall explain later. The other end of the housing is cut away, as at 9, to receive a bearing container for the centrally and longitudinally located main shaft.

This main shaft 10, and the two rock shafts 11, one on each side of and in the same hori- Zontal plane as the main shaft (Figs. 1, 3 and 4) are ournaled in a series of spaced bridge members arranged at intervals lengthwise of the housing and supported within the same; in the preferred construction these bridge members are supported by the ledges 4 and as illustrated instead of being seated directly on the ledges (see Fig. 4) they are affixed by screws 11 to and seat on a pair of bars 12, thereby forming with the bars a frame that is both rigid and of skeleton form, and these bars are seated on the ledges. The extreme left hand bridge member 13 is shown in Figs. 1, 2, 7 and 8. The intermediate bridge members 14 are all identical to the bridge member 13 (there being a suitable number of them, according to the length of the machine, but only one appearing in Figs. 1 and 2) excepting that the ends of each are offset as shown in Fig. 1 to obtain a compact arrange ment of some of the parts. The right hand bridge member 15 (Figs. 1, 2, 5 and 6) is to afford bearings whose centers are below the axes of the main and two rock shafts and for this purpose it has a pair of spaced depending webs 152 If desired, there may be antifriction bearings 16 for the main shaft arranged on some of the bridge members and also in the bracket 28 hereinafter mentioned (see Fig. 2).

The main shaft is rotated continuously and therefrom the rocking of the rock shafts is obtained as follows: The rock shafts have fixed thereon intermeshing toothed segments 17 so t-hat they rock in synchronism. On one such segment is an inward arm 18 having a slot 18 (Figs. 5 and 10) in which may be adjusted a stud 19 affording a pivot for a link 20 which connects the arm with the lever 21 fulcrumed at 22 in the depending webs 15n of the bracket 15. )Vhcn the lever 21 is oscill ated the rock shafts will be rocked through 20 and 18. Lever 21 has a roller 23 running in a cam groove 24 in a cam 24 journaled at 24b between the webs 15a of bridge member 15, this cam having peripheral teeth 24c (making it a cam-gear). and in mesh with it is a pinion 25 formed with a gear 26 and rotating on a stud 2GfL in the webs of said bridge member, and the gear 26 in turn meshes with a pinion 27 fixed on the main shaft 10. Thus when the main shaft is rotated and drives the cam-gear the rock shafts will be rocked.

In addition to bearings afforded by the bridge members the main shaft may also find bearings at the left hand end of the housing in a loop-shaped exterior bracket 28 secured to the end wall of the housing by screws 29 and having alined bearing containers 30 and 31 for the shaft, the latter being received by the recess 9 formed in said end wall. Between these bearings shaft 10 carries fast and loose pulleys 32, 32fL for receiving a driving belt.

Shaft 10 carries certain gears which are to drive the different winding units, eaclr forming for that purpose a part of a gear train. These are the spiral gears 33 fixed ou said shaft. Each bridge member is bent downwardly (Figs. 2 and 8) to accommodate the hubs 33n of these gears.

Constituted by those of the foregoing elements which are designated by the characters 10-33, inclusive, I have an organization of parts which may be assembled apart from the housing and arranged therein as will appear, supported in the housing, as on the ledges 4, to which it may be secured as by screws 34. The advantages hereof over previous machines of this class will appear hereinafter.

Each winding unit includes a rotary spindle to receive the core for the windings and a thread guide, one of which should reciprocate relatively to the other lengthwise of the spindle to form the layers of windings and one of which should progress lengthwise of the spindle to dispose such layers progressively along the spindle. A. building mechanism having these parts and functions is shown by Fig. 1, where 35 is the spindle and 36 is the thread-guide; in this example the latter both reciprocates and progresses, sliding on a control rod 37 (specifically, the extension 52 of such rod hereinafter mentioned) and having a fork 3G engaging in the peripheral groove of a nut 38 screwed on a reciprocated threaded traverse-bar 39 and having a friction-wheel 38 to peripherally engage the conical end of the package (A. Fig. 1), so that as, in the reciprocation of the nut with the traverse-bar, the frictionwheel occasionally encounters the package and the nut is thus turned and fed along the threading of the bar, the thread-guide is both reciprocated and occasionally advanced, all in a manner well known in this art.

The winding units are arranged to project from each side of the housing 1 and are the same in number and spacing at both sides thereof. The manner in which each spindle is rotated and each thread-guide traversebar 39 reciprocated and the control thereof and other details are as follows:

The spindle 35 (Fig. 13) is journaled in the opposite side walls of the housing 1 and revoluble en it is a spiral gear 40 abutting a collar 402; it is held against lengthwise displacement by a collar 41 at its butt end abutting one wall and a sleeve 42 pinned thereon and abutting the other wall, the pin (42a) protruding. A cylindrical clutch mehr ber 43, containing a spring 44 coiled about the spindle and interposed between the sleeve (whose free end the clutch member receives) and an internal shoulder 43?L in the clutch member, is splined on the spindle by means of pin 42a, which protrudes into a slot 43h thereof, being normally urged toward the gear by said spring. One of the parts 43 and 40 may have a cork disk or equivalent device 44 to afford an effective friction-clutch engagement. The clutch member has a continuous cam-contact shoulder 43c facing toward the gear, preferably conical, with which a cam on rod 37 is to engage as will appear. Each gear 40 has its toothed. periphery projecting into the oil-distributing well formed by wall 5 (Fig. 2).

The traverse-bar 39 appertaining to any spindle penetrates and slides in that wall of the housing (Figs. 1 and 4) from' which such spindle protrudes and on its inner end it has a coupling-block 45 removably secured by a set-screw 45L by which, through the medium of a link 46, it is pivotally connected with a depending crank 47 arranged on that rockshaft 11 which is relatively oppositely related to said wall of the housing (Figs. 1 and 4). Said crank is disconnectively coupled with said rock-shaft so as to partake or not partake of its rocking motion according to the state of the coupling between them, thus: In the crank is slidable a bolt or coupling member' 43 normally held by a spring 49 engaged in a notch 11b in the rock-shaft, but having a pin or projection 48a by which it may be dogged clear of said notch by a crank on the rod 37, as will appear.

The control rod 37 affords not only a guide for the reciprocating and progressing threadguide 36 but is part of a lever-like instrumentality by which the starting and stopping of the winding unit are controlled. On it are fixed a spiral cam arm 5() to engage the contact-shoulder 43c on clutch-member 43 and a crank arm 51, formed with an acting face arcuate in a plane parallel with the rod and around shaft 11 as a center (Figs. 4 and 15),

to engage projection 48a. When the control rod 37 is rocked in the direction of the arrow in Fig. 14 the cam and crank arms will become active, as will be manifest, to retract the clutch member 43 from the gear 40 to stop rotation of the spindle and to retract the bolt 48 from engagement with shaft 11 to stop reciprocation of the traverse-bar; when the control rod 37 is rocked in the opposite direction the spindle will be re-clutched with gear 40 and the traverse-bar with rockshaft 11. The control rod is in the example joul'naled for rocking in the bars 12, and it has an extension portion 52 (journaled in that wall of the housing from which the crresponding spindle protrudes) connected thereto by an oblique dove-tailed tongue-andgroove joint 372L (Figs. 4, 16 and 17) and which has an exterior handle or arm 52L which is connected by a spring 53 with a fixed arm 54 (Fig. 11) on said wall of the housing; incidentally, the plane of the joint 37a is vertical when the rod has been allowed to shift to the dotted-line position of handle 52 shown in Fig. 11, where it may abut any stop, as 55 and where its cam and crank arms have caused stopping of both the spindle and and traverse-bar, for a reason to appear. )Nhen the control rod is rocked against the tension of spring 53 and so that its cam' and crank arms permit the spindle and traverse bar to be driven it is caught and held by a detent or latch 56 pivoted to arm 54 and normally held in locking position by a spring 57. Spring 53 is of suflicient power so that whenever the latch is retracted from the handle, as by hand, it will overcome the resistance of both the spring 44 of the clutch member 43 and the spring 49 of the bolt.

As the operator faces either side of the housing the spindles and control rods 37 and traverse-bars 39 of all the units have the same relative arrangement. The spindles are arranged in pairs, those in each pair projecting from opposite sides of the housing and having their gears 40 meshing with each other (so that if the direction of rotation of one spindle is clockwise as one faces one side of the machine that of rotation of the other will be also clockwise as one faces the other side), and one such gear meshes with the gear 33. Some (as half) of the gears 33 may be spirally cut right-hand and the remainder left-hand, so that those of one of these classes neutralizes the other in producing endwise thrust on shaft 11, and in such case in order that all the spindles may rotate in the same direction (as viewed from either side of the machine) the gears 33 of one hand will engage the gears 40 for the spindles which project from one side of the machine and the gears 33 of the other hand will engage the gears 40 for the spindles which project from the other side.

The well G has at 58, Figs. 1, 6 and 6a, an oil conductor in the form of an inclined chute secured by its bracket 59 to the inner web 15a of bridge member 15 and having its outer upper edge formed to the same profile as that of and wiping against the inner face of cam-gear 24, its inner end overhanging the well 6.

Operation-Emmi the main shaft is ro tated, thereby rocking the rock-shafts 11 through the mechanism in the right-hand end of the housing` in Fig. 1 and rotating the various spindle-driving gears 40 through gears 33, the several spindles may be driven and the thread-guides reciprocated upon depressing the corresponding handles 52EL into engagement with latches 56, so that each unit cam arm 50 and crank arm 51 release the clutch-member 43 and bolt 48, thereby causing the spindle to be driven from the (constantly) rotated gear 40 and the crank 47 and hence the traverse-bar and thread-guide to be reciprocated. As the winding proceeds the friction wheel 33 of each unit will, in reciprocating with bar 39, be brought occasionally into peripheral contact with the windings in the known way and so caused to progress and advance the thread-guide in the building of the wound package lengthwise of its spindle. When th-e building has proceeded to some pre-determined extent the operator trips handle 52a from engagement with its latch, which stops the unit by causing retraction of clutch-member 43 and bolt 43.

The main shaft and each gear 33 thereof may be regarded as a rotary driver for each rotary spindle-including device comprising a spindle, its gear 40 and the clutch disconnectiv-ely connecting them. Each rock shaft and the crank 47 and link 46 thereof may be regarded as an oscillatory driver for each reciprocatory thread-traversing means comprising a thread-guide 36 and the bar 39 with which it is connected. Each of these drivers is separably connected with what it drives-- the rotary driver where the teeth of each gear 33 thereof mesh with those of a gear 40 and each oscillatory driver Where each link 46 is coupled with a traverse-bar 39. Each suoli driver also is above the instrumentality driven thereby and it is carried by supporting means, here consisting of a rigid frame comprising bars 12 and the several bridge members, with which it forms an organization of parts enterable into and removable from the housing through the top opening thereof as a unit. This construction entails great facility in properly assembling or disassembling the parts, since so much thereof as affects said organization can be performed apart from the machine, or outside of the limited confines of the housing; and if said supporting means is a frame that is rigid and also of skeleton form as herein set forth the entry of said organization into and its removal from the housing is further facilitated and convenient access to the subjacent mechanism is at all times possible. It will be understood that it is for the purpose of permitting said organization to be withc. rawn from the housing that each rod 37-52 is sectional, permitting its part 37 to be removed and its part 52 to remain behind; and in this connection it may be remarked that in the position of those rods for stopping their winding units their tongue-and-groove oints are vertical (Fig. 4).

In my lubricating system certain parts (as gears 40, see Fig. 4) dip into a body of oil (in well 6) from which it is transmitted, by their ejecting action and largely by spraying, to the various bearings, the thus-ejected oil being of course confined by the housing. The level of the oil is maintained such that said parts may dip into the oil at constant depth at any speed of the machine by forming the well with an open top and providing, exterior of the well, a lubricant receiver 7 (here formed all around the well and including the depression 8) arranged to receive substantially all vagrant lubricant discharged from the well, and also providing means (as will appear) which returns the oil from the receiver to the well at a faster rate than it is ejected from the well by said parts. The mentioned means is here afforded by camgear 24, which, by dipping into the oil in the receiver (where it is preferably deepened, as at 8, in order to immerse the cam-gear in the oil at adequate depth), in its rotation and by adhesion of the oil thereto carries it up and over to the chute 5S, by which it is wiped off the adjoining face of the cam-gear and is delivered to the well 6, the rate of return o1.' the oil to the well by this simple means being found in practice considerably to exceed that of its ejection therefrom. By vagrant oil discharged from the well I mean both what overflows the Well and is ejected by said parts and does not remain adhering to any surface Within the housing. Of course by providing an upstanding wall, 5, to form the well I bring, as it were, the level of the oil therein up to said parts.

Another novel feature of my invention eX- ists in employing a movable member (as 57- 52) not only for controlling the mechanism for rotating a spindle (as 35) and reciprocating a thread-guide (as 36) and which extends from the supporting structure (as housing l) lengthwise of the spindle, but for guiding the thread-guide in its movement lengthwise of the spindle.

In order in machines of this class to obtain from a rock-shaft (as l1) the traverse motion of the thread-guide the previous practice has been to provide a two-part device of which one part was secured on the shaft and the other movable on and interlockable with the irst part. I simplify and make sturdier the power-transmitting mechanism here involved and also cheapen the cost thereof and attain greater eiiiciency by using only one part (crank 47) and giving it a bearing directly on the rock-shaft in which the latter may oscillate, which requires only to be provided with a notch 11" (readily formed by mere routing) in order to adord engagement for an interlocking medium, as bolt 48.
