To all whom it may concern.

Be it known that I, ALBERT J. MEIER, a cltizen of the United States, residing at Glendale, inthe county of St. Louis and State of Missouri, have invented certain new and useful Improvements in Heading- Machines for Steel Packages, of which the following is a specification.

This invention relates to certain new and useful improvements in heading machines The object of the invention is to provide an improved machine of this type which will effectively and automatically secure the steel cover of a steel package in position on the latter.

In the drawings: Figure 1 is a rear elevation of a machine constructed in accord ance with the present invention, Fig. '2 is an end elevation, Fig. 3 is a bottom plan view of the heading device, Fig. 4 is a side elevation of the heading device, parts being broken away and shown in section, Fig. 5 is a top plan view of the preferred form of heading device, and Fig. 6 is a section taken on the line 6-6 of Fig. 5.

The machine includes a table .1, which rests on a bed plate 2, the latter being supported by suitable legs or standards 3. A pair of uprights 4 are rigidly secured to the ends of bed plate 2, and are provided with guide-ways-5, in which slides the. vertically reciprocating die-holder 6. The upper ends of the uprights 4, are equipped with journal boxes 7 in which is journaled a crank shaft 8, the latter bein'gdriven by a band-wheel 9, which receives its power from a belt (not the band-wheel being loosely mounted on an end of the crank" shaft 8.

A pitman 10 is loosely mounted on crank shaft- 8 and at its lower end is formed with a threaded socket in which is adjustably mounted a threaded stem 11, formed with a spherical head 12, the latter being received in a socket 13 provided therefor in the upper end of the die holder 6, and being held to effect the desired or necessary action of the die holder 6. 1

A semi-circular rib 15 on the table 1 centers the steel package in proper position beneath the heading device. The heading device, which is illustrated in detail in Figs. 3 and .4, includes an upper disk 17, formed with a stem 18, the latter beingreceived in a socket provided therefor, in the die holder 6, and being rigidly secured to the latter in any suitable manner, so as to partake of the movements thereof. A lower disk 19 is suspended from the upper disk 17 by means of bolts 20 or their equivalent, so that the lower disk 19 is capable of moving up and down on the said bolts 20, and, in order to permit of the stated movement of the lowerdisk 19, the bolt heads 21 are received in enlarged openings 22 formed in the under face of lower disk '19 of suflicient size to allow of free movement of the bolt heads 21 therein.

The disk- 17 is formed with a series of pockets 23, and the disk 19 is formed with a series of similar pockets 24, which latter are, however, very shallow, coil springs 25 being received in the oppositely disposed pockets. 23 and 24 and serving to hold the disks normally in separated relation.

The lower disk 19 is provided with a seriesof pairs of ears 26, the pairs being arranged in spaced 'relationand the ears of each pair being spaced apart to receive the fingers 27 in said space, pins'28 being employed which pass through the, ears 26 and through the fingers 27 and serve to pivotally relate said fingers to said ears. The fingers 27 are somewhat L-shape, their vertical ,portions at the upper ends thereof having rounded projections 29 and the horizontal portions at their free ends being formed with concave faces 80 and with per ends of the plates 32 abutting the shoulders 35 formed by the cut-out portions 34 and by virtue of such engagement hold the plates 32 rigidly against movement, relieving the screws 33, which have their heads countersunk, of any strain during the time said plates 32 are in action.

over the rolled edge of casing 36, the'rim tablel in engagement wit being formed with a series of lips 38. The lips 38 are formed on the rim oft-he cover prior to the latter being placed in position on the casing. v

The lower disk 19 has its lower end formed with a peripheral concave groove 39, which conformably receives and fits over the inner upper side of the rim of the cover 37, as clearly depicted in Fig. 4, the function of the disk 19 being that of holding the cover firmly in place during the bending of the lips 38. The upper disk 17 is formed with a downwardly extending annular guide member 40 which is slidingly received 1n an opening 41, provided therefor in the lower dlsk 19. I

In operation the casin 36 is placed on it rib 15, the cover being placed on the casing 36 and so positioned with respect to the fingers.27, that the latter will be in register with the respective lips of thecover, it being understood that there are asmany on the rim of the cover.- The heading device is then lowered, the lower disk 19 engaging the cover of the package and the rim of the cover enters the annular groove 39 of said lower disk before the die holder 6 reaches the limit of its downward stroke. After the lower disk 19 engages the cover,

in a manner depicted in Fig. 4, the cover prevents same from further downward movement, with the result that the upper disk 17 continues to move downwardly and thereby compresses thesprings 25, which springs in turn exert pressure on the lower d sk and the latter being in engagement with the cover holds same firmly in place on the casing. At the same time the wedge-shaped or cam-faced plates 32 borne by the upper disk 17 engage the rounded projection 29 of the fingers 27 that are pivoted to the lower disk 19, movin the vertical portions of the fingers outwar ly and effecting correspondin inward and also upward movement ,0 the horizontal ortions of the fingers, whereby the roun ed noses 31 of thefingers bend the lips 38 of the cover rim over the rolled upper edge of the casing 36, as clearly illustrated inFig. 4; On the idle or upward str ke of the die holder and fingers 27 as there are lips ferred form of the heading device is illustrated, which is especially adapted to secure or look the cover on the casing, in a manner disclosed in my co-pending application filed June 5, 1911, Serial'No. 631,287. In the said Figs. 5 and 6, the upper disk 17 has a depending (guide member 40 which is slidingly receive in an opening 41, provided therefor in the lower disk 19, the upper disk having a stem 18' for securement to the die holder, as described above in connection with the preferred form of the invention. Screws 20 are secured to the upper disk 17 and have their heads 21' received in enlarged o enings 22 formed in disk 19. Fingers 2 are pivoted to rods 28' which latter are received in openings provided therefor and which extend through the eriphery of the lower disk 19 as shown in otted lines in Fig. 5, the rods being held in place by means of screws 42 whose ends are pointed and received in depressions propose of preventing longitudinal movement of the rods 28'.

Each finger has a rounded nose'31 at its lower end and a rounded projection 29 at its upper end. Springs 25' are interposed between the disks 17 and 19 and act in a manner precisely as described in connection with the other form of the invention. The upper disk 17 is formed with a series of openings 43, the outer walls of which are inclined and receive the wedge or cam-faced lates 32', secured by means of screws 33'. mall coil springs 44 are received in pockets provided therefor in the lower disk 19 and exert pressure against the rear faces of the latter outwardly in engagement with the lates 32. The lower disk 19 is also Onned with openings 45 in which the lower ends of the fingers are pivoted. The disk Iconcave groove 39 which receives the rim 38' of the steel cover, said rim bein of inlvertedU-sha e in cross-section an being annealedso't at the rounded noses of the pivoted fingers will force or press the inner side' ortions of the rim outwardly, thereby formlng indentations which latter en age under the rounded reinforced upper e es of the casing 36- of the steel package, as epicted t0 the left of Fig. '6, as distinguished In Figs. 5 and 6 of the drawings the previded therefor in the rods 28', for the purfingers 27 and move the upper ends of the j 19 is formed with an inner circumferential casing, and the latter is properly positioned on the table 1, and on the working or down stroke of the heading device the lower disk ,19 engages the cover, the rim of the latter entering the groove 39 before the die holder 6 reaches the limit of its downward stroke. After the lower disk 19 el'lgages the cover, the latter prevents same from further downward movement, with the result that the upper disk 17 continues 'to move downwardly and thereby compresses the springs 25, which latter in turn exert pressure on the lower disk with the result that the lower disk holds the cover firmly in engagement with the casing. At the same time the wedge-shaped plates 32 borne by the upper disk 17 engage the rounded projections 29 of the fingers 27, moving the upper ends of the latter inwardly and the rounded noses 31 thereof outwardly, with the result that each rounded nose forms an indentation in the rim of the cover as depicted to -the left in Fig. 6. On the idle stroke of the heading device, the springs 25 are permitted to expand, which efi'ects movement of the disks 17 and 19 to their relative extremes of movement, and consequently causes the plates 32 to move away from the projections 29, whereupon the springs 44 expand and move the upper ends of the fingers 27 outwardly, causing thenoses 31 of the fingers to move inwardly so as to permit said noses to pass the indentations formed thereby. i j i In carrying out the present invention the heading device may, obviously, be used in connection with any suitable power, press, the one illustrated in the drawings and above described being an example of a power press which may be employed. The band-wheel 9 has connection with a stopclutch of any construction, the latter being actuated by the foot lever 46, which, when depressed, causes the stop-clutch to .lock the band-wheel 9 to the crank-shaft 8 effecting a complete revolution of the latter and thereby lowers and raises the heading device.

The stop-clutch is one of the one-revolution type and may be like the clutch disclosed in the United States Patent No. 394,976, granted December 25, 1888, or any other one-revolution clutch.
