FIBER-GATHERING CAN FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 750,131, dated January 19, 1904.

Application filed July 25, 1903. Serial No. 166,972. (No model.) I

To all whom it may concern.-

Be it known that I, Guino STIEHLE, a subject of the King of Bavaria, residing at Seltmanns, post-station Harbatzhofen, Allgau,

' 29, 1902. In this connectionthe invention providing practical and expeditious means for removing and replacing the indivldual cushion-blocks.

With these and other objects in view the injvention consists in the'novel construction,

combination, and arrangement of parts hereinafter more fully'described, illustrated, and claimed.

The essential feature of the invention in-' volved in the means for yieldingly gripping the individual cushion-blocks is susceptible to structural modification without departing from the scope of the invention; but a preferred embodiment thereof is shown in the accompanying drawings, in which- Figure 1 is a plan view, partly in section, of a fiber-gathering can embodying the present invention. Fig. 2 is a sectional view of the lower portion of the can-body, exposing the means for holding the elastic cushion-blocks and the removable can-bottom. Fig. 3'is a detail view showing more clearly the formation and attachment of the resilient clampingring to the bottom edge of the can-body. Figs.

4 and 5 are an edge view and elevation, respectively, of one of the removable and replace able cushion-blocks. I

Like references designate corresponding parts in the several figures of the drawings.

7 The body of the can or pot is designated by the reference-letter a and is of the usual cylindrical form. A distinctive feature of the present invention resides in associating with the lower edge of the body a an interiorly-arranged resilient clamping-ring b, which performs the dual function of detachably holding in place a series of individually removable and replaceable cushion-blocks c and the canbottom f, which latter is arranged inside of 'the'circle of the ring and is held in position thereby through a spring clamping pressure. The interiorly-arranged clamping-ring Z2 is in the form of an open rim'disposed concentrically to the can-body and positioned inside of the lower edge portion thereof. The said open rim constituting the ring is of an inverted-U shape in cross-section to provide a pocket for receiving and clamping in place the individual cushion blocks 0, which provide a cushion-base for the can, pot, or receptacle.

Referring more particularly to the detail formation of the open U-shaped clampingring 6, it is to be observed that the outer leg or member thereof is rebent or folded to produce the folded fastening-flange h, bent around the lower edge of the can-body and lying upon the outer side thereof. This fastening-flange is firmly secured to'the canbody,"preferably through the medium of a series of securingrivets 2', which are passed through the said flange, the can-body, and also through the outer leg member of the U-shaped ring. This construction provides a double reinforcement for the lower edge of the can-body, respectively at the inner and outer sides thereof, while at the same time effecting a strong support for the clamping portion of the ring. To facilitate the positioning of the securingrivets i, the inner yieldable leg member of the ring may be provided directly opposite the radial plane of the rivets with the holes is, the edges of which holes are preferably upset outwardly to produce gripping edges proj ecting into the pocket of the ring. These gripping edges bite into the inner faces of the cushion-blocks when in position, and thus assist in holding the same in place. To increase the resiliency of the inner yieldable' leg memher of the ring, the said leg member is provided with a series of transversely disposed slits (Z, which break the inner leg member into a multiplicity of spring clamping-tongues, which are strained outward against the cushion-blocks when the can-bottomf is in position. In connection with the positioning of the can-bottom it is to be observed that the inner yieldable leg member of the ring is preferably provided with inturned rest ledges or lips g, projecting from the spring-tongues and providing a rest upon which the bottom f rests when forced into position within the circle of the ring. This construction, however, may be varied without departing from the invention; yet with the construction described the bottom can be readily removed by simply displacing it upward from the ring, and it should also be noted that when the bottom F is forced into position within the circle of the ring the same forces the clampingtongues in an outward direction, whereby the cushion-blocks are firmly clamped in the ring.

Any desired number of the individual elastic cushion-blocks 0 may be employed; but there is preferably one of said blocks associated with each spring clamping-tongue of the ring, as plainly shown in Figs. 1 and 2 of the drawings. It is preferable also to suitably aflix to the outer side of each block 0 a metallic protective facing-plate m, which reinforces the cushion blocks and protects the same against shock from the outside. The said facing plate m for each block is usually provided with a hole 0, the edge of which is upset inwardly to produce a gripping edge, which bites into the outer face of the block and materially assists in holding the same in place. The several cushions, with their facing-plates, project below the plane of the bottom edge of the can-body and of the clampingring to provide a reinforced cushion-base for the can or pot. When said cushions and their plates are worn out, the same are removed and replaced individually without disturbing any of the others.

From the foregoing it is thought that the construction and many advantages of the herein-described canwill be apparent without further description.

Having thus described the invention, what I claim, and desire to secure by Letters Patent, 1s

1. In a can of the class described, the combination with the can-body, of an open resilient clamping-ring secured within the lower edge of the body and having a multiplicity of' spring clamping-tongues, and a plurality of cushion-blocks removably and replaceably fitted in the ring and each held by a tongue.

2. In a can of the class described, the combination with the can-body, of a clampingring carried by the lower edge of the body and provided with a multiplicity of spring clamping-tongues, and a plurality of cushionblocks each removably and replaceably held in place by a tongue.

3. In a can of the class described, the canbody, an inverted-U-shaped ring having a folded fastening-flange secured around the lower edge of the body and also provided with an inner yieldable slitted leg member having a multiplicity of spring-tongues, and a plurality of cushion-blocks each held in place by a tongue. I

f. In a can of the class described, the canbody, an inverted-U-shaped ring secured to the lower edge of the body and having an inner yieldable leg member provided with an inturned rest-leg, the cushiomblocks held in place within the ring, and the can-bottom fitted in the ring upon the rest-flange.

5. In a can of the class described, the combination with the can-body and the resilient clamping-ring, of a plurality of cushion-blocks separately held in place by the spring clamping pressure of the ring and each provided upon its outer face with a protective metallic plate, also held engaged therewith by said pressure.

In witness whereof I have hereunto set my hand in presence of two witnesses.
