6 Claims. (Cl. 294-93) This invention relates to lifting tools and more particularly to a device useful in removing cakes of artificial yarn from spinning buckets.
The present invention represents an improvement over prior art devices of this type in that it provides a plurality of supporting bars for the cake which extend completely from one end of the cake to the other. These bars are connected by means of a parallelogram linkage to provide straight line radial movement thereof. This feature together with the length of the bars and their convex outer configuration minimizes or eliminates damage to the fibers of the cake.
A primary object of the invention, therefore, is to provide a collapsible lifting tool for yarn cakes having a plurality of bars extending axially from one end of the cake to the other.
A further object of the invention is to provide an improved yarn cake lifting tool in which the bars or members of the tool which engage the bore of a cake move radially in a straight line to prevent chafing or damage to the yarn fibers in the bore of the cake.
Further objects will be apparent from the specification and drawings in which:
Figure 1 is a vertical sectional view of a cake lifting tool constructed in accordance with the invention as seen at I-I of Figure 2;
Figure 2 is a top view of a lifting tool constructed in accordance with the invention;
Figure 3 is a view similar to Figure 1 but with the cake engaging bars expanded in lifting position; and
Figure 4 is a sectional detail as seen at IV-IV of Figure 3. i
The invention comprises essentially the provision of a plurality of, preferably three, elongated cake. engaging bars or members which are slidably connected to a spider at each end of the bars. The spider is provided with a rigid handle and a spring-loaded plunger extends through the center of the spider to control the radial movement of the bars by means of suitably connected links. When the handle on the plunger is pressed towards the rigid handle to compress the spring, the bars are moved radially outward so that the outer faces of the bars are parallel to the centerline of the plunger at all times.
Referring now more particularly to the drawings, a preferred embodiment of the invention comprises a spider 5 having three slotted arms 6, 6, 6 which extend radially from the center of the spider at included angles of approximately 120". It will be understood that the lifting tool may have any number of arms more than two. The cake engaging members or bars 7, 7 are of T- cross-section (Figure 4) the outer faces thereof being convex and of approximately the same radius as the bore of a cake 8 shown in phantom in Figures 3 and 4. The lower ends of each bar are curved inwardly at 9, 9 to facilitate the insertion of the lifting tool in the cake Without damage. The upper ends 10, 10 of each bar are flattened and extend through the slots 11, 11 in the side arms 6, 6 of the spider 5. Pins 12, 12 suitably retain the bars 10 in the spider and permit free radial movement of the ends 10 in the slots 11.
The center of the spider 5 is provided with a sleeve 15 which is desirably lined with a bushing 16 through which a rod or plunger 17 is slidable. The rigid handle 18 is secured to sleeve 15 so that the handle 18 and the spider 5 form a unitary structure. A second handle 20 is connected to the top of. plunger 17 and retained thereon by means of a lock nut 21 and the plunger is controlled in its sliding action through bushing 16 by means of a helical compression spring 22 extending between nut 21 and a counterbore in handle 18.
On the opposite side of spider 5, the plunger 17 is provided with a small upper spider 25 adjustably secured thereto by means of a set screw 26 and a small lower spider 27 secured to the plunger by a set screw 28. Spiders 25 and 27 are bifurcated, as shown in Figure 4, and each pivotally supports three links 29, 29, 29 which are desirably of equal length. The outer ends of links 29 are bifurcated and pivotally connected to their respective bars 7, 7 at 30, 30.
In the unstressed or collapsed condition shown in Figure 1, plunger 17 is urged upwardly by spring 22 which in turn causes collars 25 and 27 to retract bars 7, 7 radially inward through links 29, 29. The bars, however, are maintained parallel to the centerline of the plunger due to the control of the axial position of the bars by pins 12, 12. When it is desired to lift the cake of yarn or some other annular object, the device is inserted into the bore of the cake as shown in Figure 3 and the handles 18 and 20 are squeezed together to urge the plunger 17 downwardly and thus expand the bars 7, 7 against the bore of the cake. Due to the radial straight line motion of the bars, there is no slidingtor axial movement whatever of the bars in engaging the bore of the cake. Furthermore, the length of the bars is such that the maximum axial area of the bore is contacted by the convex faces of each bar.
it will be thus understood that I have provided a relaatively simple, inexpensive cake lifting apparatus by which delicate annular objects may be lifted from place to place without injury to the bore thereof.
Having thus described my invention, I claim:
1. A lifter for yarn packages and the like comprising a supporting member, walls defining at least two substantially radially extending slots in said supporting member, a cake engaging bar extending through each of said slots and freely slidable therein, means for axially retaining each of said bars in the slots, a sleeve rigidly mounted on said supporting member, a plunger extending through said sleeve, a fixed handle on said sleeve, a handle on said plunger, and a plurality of links pivotally connected between the plunger and the arms to move the arms radially with respectto the centerline of the plunger.
2. Apparatus as defined in claim 1 in which the supporting member comprises a spider having three arms spaced substantially at apart and in which there is a bar in each arm of the spider.
3. Apparatus as defined in claim 1 having a parallelogram linkage connecting the bars and the plunger.
4. Apparatus as defined in claim 1 having a compression spring between the plunger and the supporting member.
5. A lifter for yarn packages and the like comprising a supporting member, walls defining at least two substantially radially extending slots in said supporting member, a cake engaging bar having a flattened end extending through each of said slots and freely slidable therein, an elongated convex face on each of said bars, means for Patented Mar. 13, 1956 slidablyflretaining ,a flattened end of each of said bars in the slots, a sleeve rigidly mounted on said supporting member, a plunger slidably supported in said sleeve, a handle secured to said sleeve, a handle on said plunger, a-compression spring operatively associated between said handles, and a parallelogram linkage connecting the other end of the plunger with the bars whereby relative movement of the plunger in the sleeve moves the bars radially with respect to the 'centerline of the plunger.
6. Apparatus in accordance with claim 5 in which the length of the parallelogram linkage is such that the outer 4 faces of the bars are parallel to the centerline of the plunger at all times.
