MATERIAL WORKING APPARATUS Filed Jan. 8, 1944 2 Sheets-Sheet 1 AE. JARVIS WVENTO m1 KELLER BY I A T TOPNEY Oct. 30, 1945. A, E. JARVIS MATERIAL WORK INC: APPARATUS Filed Jan. 8, 1944 2 Sheets-Sheet 2 I 0 FIG. 3

efimm A 7' TORNEY Patented Oct. 30, 1945 MATERIAL WORKING APPARATUS Albert E. Jarvis, Arlington, and Willia m J. Keller, Jersey City, N. J., assignors to Western Electric Company, Incorporatei New a corporation of New York York, N. Y.,

Application January 8, 1944, Serial No. 517,584 10 Claims. (01. 9011) This invention relates to material working apparatus, and more particularly to apparatus for slotting tubes. I

An object of the invention is to provide a material working apparatus, more particularly one which is simplein structure and highly eificient in cross-slotting tubular articles.

Other objects and advantages will be apparent from the following detailed description when considered in conjunction with the accompanying drawings, wherein:

Fig. 1 is a side elevational view partially in section of an article holding and feeding unit;

Fig. 2 is a fragmentary side elevational view of the apparatus, a portion thereof being shown in section;

Fig. 3 is a fragmentary sectional view taken substantially along the line 3"3 of Fig. 2;

Fig. 4 is a fragmentary sectional view taken substantially along the line 4-4 of Fig. 2;

Fig. 5 is a fragmentary end elevational View taken substantially along the line 5-5 of Fig. 2;

Fig. 6 is an enlarged fragmentary detailed View of a portion of the structure shown in Fig. 4; and Fig. 7 is a fragmentary end elevational view of the unit shown in Fig, 1, this view being taken substantially along the line of Fig. 1.

Referring now to the drawings, attention is first directed to thearticle holding and feeding unit indicated generally at In in Fig. 1. This unit includes a hollow handle portion apertured, at I2, to receive an end M of a lever IS. The lever I5 is pivotally supported at It and has 7 a handle portion I! which may be actuated by the operator upon gripping both the handle portions and-||. An actuating pin l8, movably disposed in an aperture IQ of a threaded end 20 of the handle I is actuated by the end l4 of the lever |5 to move a chuck 2| into open position. The chuck 2| has a housing 22 mounted upon the threaded end 20 of the handle H, with a conical aperture 23 in the forward end thereof adapted to receive the chuck 2|. The chuck 2| is of the contour shown, having a tubular portion 25, notched longitudinally as at 26, providing resilient portions which normally urge jaws 21 thereof outwardly when the chuck is moved into open position. A member 30, threadedly mounted upon the inner end of the chuck 2|, is slidably disposed in the housing 22 and is apertured, at 3!, to receive the actuating pin l8. A compression spring 32., disposed in the housing 22 concentric with the adjacent chuck portion, engages the member 30 to normally urge the chuck 2| into closed position, and, through the" tapered or co ical surfaces thereof indicated at 33, engaging the conical aperture or opening 23 to causeclosing of the chuck to grip an article 35. The article in the present instance is tubular in general contour, it being'formed of any suitable material such as brass. It will, therefore, be apparent that by actuating the lever l5, the end portion l4 thereof will push the rod or pin I8 toward the chuck end of the unit, first moving the chuck 2| relative to its housing 22 against the force of the spring 32, to cause opening of the chuck, and while in this position an article previously held thereby may be released therefrom and another like article 35 may be disposed in the chuck. Shoulders 36 in the mouth or gripping jaws of the chuck locate the article at a definite position with respect to the chuck when closed. Closing of the-chuc'k'is brought about through the force of the spring 32 when the handle portion ll of the lever l5 is released. I w

The cutting means includes cutting elements or saws 38 and 39 mounted upon a rotatable shaft for continuous rotation duringthe use ofthe apparatus' A holder or body 4| is disposed adjacent the cutting elements 38 "and 39 and supports a housing 42 for the latter. Apertures 44' and 45 are formed in the holder 4| of contours similar to the housing '22 and its associated chuck 2|, to receive the unit l0 when the article 35 is to be fed to the cutting elements. Associated with the apertures 44 and 45 are grooves 46 and 41 respectively, these grooves exte'nding in'transversedirections as illustrated in Fig. 5. Thegrooves 46 and 41 are for receiving the lever 5, the latter being substantially square in cross-section as illustrated in Fig. 5. Through the aid of the groove 46. the unit I0 is located in agivenposition to locate this article 35 relative to the cutting element 38. The groove 41 is so positioned as to control the unit In through the aid of the lever 5, tocause the cut performed on the article 35 by the element 39 to be at right angles withrespect to that performed by the cutting element 38 on the article. When the article 35 is cut by'the element 38, the portionsof the article on each side of the element 38 are selfsupporting against collapsing. However, upon positioning of the unit III with the article 35 in the aperture 45, the article has previously been slotted and requires additional support for the side portions thereof upon each side of the element 39. At this position supporting plates or members 49 are disposed in positions to be received in the notches or slots previously cut into the article by the element/38. The plates 49 are that the inner ends of the apertures 44 and 45 are tapered, as at 53, to receive the end of the chuck 2|, straight portions 54 of the apertures providing abutting surfaces to locate the unit ID in these apertures. Communicating with the apertures 44 and 45 are article receiving apertures 55 leading toward their respective cutting elements 38 and 39. Also, slots 56 are provided in the holder 4| for the cutting elements 38 and 39. Downwardly projecting passageways 58 (Figs. 2, 4 and'5) eliminate the possibility of particles interfering with the accurate location of the unit In in each of the apertures 44 and 45, these. passageways communicating with the apertures adjacent the inner ends thereof and extending downwardly andoutwardlythrough the holder 4|.

During the operation of the apparatus, theunit I is provided with an article 35 in its chuck 2| located therein by the shoulders 36, the chuck having been actuated into open position through the aidof the lever l5. By releasing the lever l5, the-chuck is closed through the force of the spring 32 and at this timethe article 35, through the aid of the unit l0, maybe moved throughthe apertures 44 and 45. As the unit is moved into the aperture, the article 35, upon reaching the cutting element 38, is slotted to a given depth limited by the abutting surface 54-which the unit l0, particularly the chuck 2| thereof, engages. This inward movement of the unit I0 is controlled through the groove 46 and the lever l5, causing the article to be slotted in'a given direction. The unit I!) with the slotted article is removed from the-aperture 44, and without varying the location of the article in the unit they are disposed in the aperture 45, their positions therein being controlled by the notch or groove 41. Here again the article 35 is slotted, the slots at this time extending at right angles with respect to the previous slots formed by the cutting element 38. During this last slotting'operation the portions of the article are held against collapsing by the plates 49. At the completion of the slotting operation, the unit ID with the slotted article 35 may be removed from the aperture 45, after which the slotted article may be moved from the unit during-actuation of the lever l5, at which time a new article may be disposed in the unit and the slotting operation repeated.

Although specificimprovements of the invention have been shown and described, itwill be understood that they are but-illustrative and that various modifications may be made therein without departing from the, scope and spirit of this invention as defined by the appended claims.
