srmnma. HEAD FOB TUBING MACHINES.

Application filed December 28, 1918. Serial 10/847,569.

Another object is to provide a device of b this character, which is calculated to increase the output of the machine.

Another object consists in providing a device of this character, which may be easily and quickly assembled for operation and disassembled for cleaning, repair or replacement.

Another object consists in providing certain improvements in the form, construction and arrangement of the several parts whereby the above named and other ob]ects may be effectively attained.

Machines of-this character are designed to operate u on rubber compounds including various su stances during the processof reclaiming the rubber and these materials vary greatly in consistency. Consequently, it has been found that strainer heads heretofore in use have not been fully adequate to handle these different materials with satisfactory results in all respects. My mvention is designed to overcome this disadvanta e.

h practical embodiment of the invention is represented in the accompanying drawings, in which,

Fig. 1 represents a face elevation of the device partly broken away.

Fig. 2 represents a longitudinal section taken in the plane of the line IIII of Fig. 1, looking in the direction of the arrows.

Fig. 3 represents a transverse section taken in the plane of the line IIIIII of Fig. 2, looking in the'direction of the arrows.

Fig. 4 represents a detail transverse section taken in the plane of the line IV--IV of Fig. 2, looking in the direction of the arrows.

Fig. 5 represents a fragmentary section taken in the plane of the line V of Fig. 3, looking in the direction of the arrow.

Fig. 6 represents a view similar to Fig. 5, with certain parts in different positions.

The strainer head is adapted for use in connection with a tubing machine of standard or appropriate form and is, as will be understood by operatives in this indust intended to be secured to the cylinder iii the tubing machine in which the screw or plodder operates.

In the present instance. the cylinder is denoted by 1 and the liner for its bore by 2. 'l he screw or plodder which operates in the sang bore in the usual manner is indicated The strainer head includes an inner tubular member 4, which is flanged and threaded on its inner end for engagement with the mteriorly threaded end of the bore liner 2, as clearly indicated at 5. The arrangement is such that the inner end of the member 4 abuts a shoulder on the bore liner 2, while the forward end of the latter abuts the flange on the member 4, thereby establishing a firm inter-engagement, with the interior of the member 4 in precise alinement with the bore of the liner 2. As a result of this arrangement, the inner member 4 constitutes, in effect, a forward extension of the cylinder bore in which the forward end of tie plodder 3 is designed to operate. It is convenient, from a manufacturing point of view, to have the member 4 secured to the bore liner 2 as described, but this is not essentlal and it might be advisable in man cases to form the member 4 integral with the liner 2.

The part of the member 4, which protrudes from the cylinder 1, is provided with a multiplicity of small circular perforations f5 and the front end of the said member 18 open. g

The head also includes an outer member or acket 7 that is also cylindrical in form and has its walls provided with perforations 8, that are similar in cross section to the perforations 6 in the inner member 4.

The outer member 7 has its front and pro-- vided with an exteriorly threaded rim 9, which is fitted to be engaged by a locking nut 10. An end plate 11 fits within the front end of the outer member 7 and is held in position by being clamped between the front end of the inner member 4 and the nut 10. This end plate 11 also has a large number of circular perforations 12 formed therethrough and it will be observed that these perforations are greater in cross section at their outer part than at their inner part. The arrangement of all the perforations described is such that those in the tubular H the rear end members 4 and 7 lie at right angles to the axis of the screw 3, while those in the end plate 11 are parallel to the axis of the screw. 7 v p The inner diameter of the outer member 7 is somewhat greater than the outer diameter of the inner member 4, so that a space 13 is left between the said members w ien the outer is put over the inner, like a jaclret as clearly shown in Fig. 2, and a cylindrica screen or netting 14 is located between the said members 4 and 7 and against the interior of the outer member 7. A fiat screen 15 is located against the inner face of the end plate 11 and is clamped in position between the said plate and the inner member 4. It will be noted that as the end member 11 is fitted within the front endof the outer member 7 and clampel by-the locking'nut 10 to the front end of t e inner memeber 4, the members 4 and 7 are in spaced relation at their front ends, while a spacing rin 16 is located between the members 4 and at their rearends in order to holdthem in spaced relation at this point.

It is desirable in many cases to have the

perforations

6 and 8 in the inner and outer tubular members 4 and 7 in exact alinement for the proper operation of the machine and, in order to effect this alinement and assure its retention, I provide a dowel 17 that projects from the flange on the rear part of the member 4 and is calculated to enter a corresponding recess 18 formed in the outer member 7. When the dowel enters the recess, the inner and outer members have their perforations in exact alinement.

My invention includes means for firmly securing the outer member 7 and parts carried thereby to the cylinder 1 in operative position and for permitting the expeditious removal or detachment thereof for any desired purpose. This means includes an annular plate 19, which has a series of circumferentially elongated slots 20, that are designed to receive stud bolts 21, which are threaded into and project from the front end of the cylinder 1. These arcuate slots 20 permit theplate 19 to be moved in a rotary direction a short distance on the bolts 21, and suitable nuts 22 serve to secure the plate 19 in any desired position with res ect to the bolts 21.- The inner edge of the p ate 19 is cut away as indicated at 23, thereby forming a rib 24. A clamping ring 25 has its outer periphery fashioned to correspond with the recess and rib 23, 24, on the plate 19, and is adjustably and removably secured to the plate 19 by clamps 26, which are pierced y cap screws 27 threaded into the ring 25. The operation of the .clamps is to grip the rib 24 on the plate 19 between the complementary part on the outer periphery of t e 25 and the clamps, so as to such discrepancy ma frictionall hold the ring 25 in engagement with the p ate 19.

' The inner periphery of the ring 25 has a series of se ental lugs 28 formed thereon, which over ap and mate 'with a corresponding series of segmental lugs 29, which project outwardly from the rear end of the outer tubular member 7. These

lugs

28, 29, have their sides cut on radial lines and the lugs 29 are of such size and form that they can enter the spaces between the lugs 28.

This construction enables the outer tubular member 7 to he slid axially rearwardly with respect to the locking ring 25, during which movement the lugs 29 pass between the lugs 28. lVith the parts in this position and with the nuts 22 on the bolts 21 slightly loosened, the plate 19 and locking ring 25 carried thereby may be moved in a circumferential direction until thelugs 28 pass over and register with the ln s 29, thereby lockin the tubular member 7 in place on the cy inder 1. It will be observed that the slots 20 in the plate 19 are of such length as to just about permit circumferential movement of the plate 19 adequate to move the lugs 28 from lockin position in front of the lugs 29 to unlocking osition in line with the openings between t e lugs 29, and an equivalent movement in the opposite direction is also, of course, permitted. Hence, to detach the outer member 7 and parts carried thereby, it is simply necessary to insert a spike in the socket 3O fashioned in the periphery of the plate 19, loosen the nuts 22, and then swing the said plate until the free ends of the slots 20 engage the bolts 21. In this position, the tubular member 7 may be removed by an axial forward movement.

To replace the said parts, the member 7 is slid rearwardly in an axial direction and the plate 19 swung cireumferentially until the opposite ends of the slots 20 again engage the bolts 21; after which the nuts 22 may be tightened for securing the arts in place. During thisv movement of t e plate 19, the ring 25 moves with it and acts as a part thereof. However, in case the bolts 21 or slots 20 should be slightly misplaced in their operative relationship with respect to the outer tubular member 7, or, if for any other reason, the In 28 should not exactly coincide with the figs 29 when the plate 19 is turned so that the bolts 21 abut one end of the slots 20 and exactly in line with the spaces between the lugs 29 when the other ends of the slots 20 abut the bolts 21, be com nsated by loosening the screws that hol the clamps 26 in position and movin the locking ring 25 circumferentially a suitable distance in inner and outer may be tightened, thereby pausing the clamps 26 to firmly lock the mug 25 to the plate 19.

As already described, there is a space between the inner tubular member 4 and the outer member 7, while the screen 13 is also spaced from the inner member 4. As a result of this construction, the material being operated upon is broken up by the holes 6 in the inner member 4 and permitted to surge or eddy around a little between the inner and outer members before passing through the screen 13. This protects the screen and renders it more durable and effective, as well as avoiding the clogging thereof for a longer period of time. By perforating 4 and 7, the outlet for material is greatly increased, thus increasing the capacity of the machine. By increasing the cross sectional size of the outer part of the holes 12 in the end plate 11, the material is allowed to expand as it passes therethrough, thus decreasing the resistance and hence increasing the output of the machine.

It will be understood that various changes may be resorted to in the form, construction and arrangement of the several parts without departing from the spirit and scope of my invention, and hence I do not intend to be limited to the details herein shown and described, except as they may be included in the claims.
