LOADING nacnmn. 7

Application filed February 9, 1926. Serial No. 87,187.

This present invention relates generally to a loading machine and as illustrated herein is applied to a loading machine of the type wherein the several elements of a cartridge are automatically assembled .to form a com-- be used advantageously with machinery of various typesto which it may be applicable, but for the purpose of illustration, one of such uses is illustrated and described herein as being applied to a loading machine. In such application of the invention certain other improvements. forming part of the invention, are hereinafter set forth, being effective in the construction and arrangement of the associated parts of the loadingmachine, and to some degree render this invention applicable and whereby the maximum advantages may be obtained therefrom.

It is the object of this invention, among other things, to provide in a machine, wherein several elements are assembled to form a unitary structure or article, means for inspecting the article during the progress of assembly to determine if the-parts are. normal and being assembled in a predetermined manner, and in connection therewithto provide simple and effective means that will eject all of the articleswhichfail to meet the inspection requirements and without stopping the entire machine or disarranging any of 'its parts; in brief, to produce a machine wherein the imperfectly assembled article may be automatically ejected at one station and those which are found correct by such inspection are ejected at another station, these inspecting and ejecting operations being continuous and uninterrupted irrespective of the result of the inspecting operations.

This invention has for its purpose the accomplishment of these and other objects, and consists in mechanism having certain details of construction and combinations of parts as will be hereinafter described and more particularly pointed out in the claims.

In the drawings, wherein like numerals of reference designate like parts in the several figures;

Figure 1 is a front view of my machine having my improved mechanism connected therewith and designed to be used for automatically producing completed cartridges;

Figure 7 is an elevation of that portion of the inspecting mechanism that is connected with the rear of the machine, as shown in Figure 1;

Figure 8 is a plan view thereof with some of the adjacent mechanism partly in section; I

Figure 9 is a transverse sectional detail of the parts taken substantially on line 9-9 of Figure 7;

' Figure 10 is a face view of the lifter wheel 1 Figure 11 is a fragmentary side elevation thereof; and

Figure 12 is trip plates. i I In loading machines of the type herein an elevation of one of the referred to, the cartridge is supplied with a to complete the cartridge. Obviously, if the bullet feeding mechanism fails and no bullet is inserted in the shell, the cartridge is in- 'com'plete, asis also the case. if the charge of powder is either too large or too small.

Devices have heretofore been used to in spect these successive operations, but so far attention.

moves the imperfect cartridge. If, per-' chance, the alarm is not noticed, the machine.

continues its operations, produces imperfect shells, and frequently scatters the powder about where it is liable to do more or less damage.

.The greater the number of machines under the control of one operator, of'course, increases the danger of failure to note the alarm. The stopping of the machine to remove the imperfect article, readjusting the parts and restarting the same, materially slows down the s eed of production.

In my device ereinafter shown and described, I have so arranged the parts and mechanism that if any one of the several inspecting devices discloses an abnormal condition, such imperfect article will be automatically ejected at a predetermined station without stopping the machine or requiring the attention of an operator.

My invention, as shown in the drawings, is applied to a cartridge loading machine, the details of which, except as the same may apply to this invention, are not essential. However, as shown, the loading machine consists of a bed 20,-having frames 21, 22 and 23 fixed thereto, and connected with each other on the top thereof by the plate 24. Within the frames is a shaft 25, which may be rotated by gears 26 or other means.

Upon one side of the bed is a rotary mech anism 27, by means of which the cartridge shells 28 are advanced to a point where they may be received b suitable carrier mechanism 29, whereby t e cartridges may be successively advanced to several stations, either for operations thereon or other reasons, such st-ations'in the machineshown being fifteen in number, and vertically are indicated by the broken lines in Figure 1, severally designated 1 to 15, inclusive. 2

Fixed to the frames 21, 22 and 23 is a slide bracket 30, within which there is mounted a plurality of slides 31, 32, 33, 34, 35, 36, 37 and 38, which are held therein against outward movement by .caps 39. These slides are all ofsubstantially the same construction, modified only in so far as it may be necessary for the particular operation to be performed thereb I On the shaft 25 are a pl iirality of cams 40, one cam for each slide. Motion is imparted from each of the cams 40 to aslide through the rock arm 41 on the shaft 42, having a cam roll 43 mounted therein, which is held against the face of the cam by an auxiliary rockarm 44 on the shaft 45 carrying a cam roll 46, which also bears against the periphery of the cam 40. These two rock arms are connected by a link 47, pivoted to the cams, 4O epends upon the relative time of movement of the slide actuated thereby.

The powder is conducted to the cartridge from a source of supply through a conduit 51 into a receptacle 52, from which it is delivered to a cartridge shell at station 7 by means of a slide 53 actuated through the rock lever 54, which derives its motion from a cam 55 upon the shaft 25.

The 'bullets'are conveyed to station 12 for assembly with the. cartridge shell through a tube 56. p

Carrier mechanism 29 is in part actuated through the rock lever 57 connected by a link 58 to the slide 38 and the rock lever59 actuated by a cam 60 on the shaft 25.

The cartridge shells 28 are taken from the rotary mechanism 27 and conveyed in a substantially straight path underneath all of the slides above referred to and if all the operations are normal, the completed cartridge is ejected at the end of this path. At stationsl, 2, 3, 5, 6, 8 and 9, no operations are performed.- At station 4, the punch 61' enters the open mouth of the cartridge shell and irons out any nicks or indentations therein. At stations 7, the charge of powder is placed in the shell. At station 10, there is an inspection for a heavy charge of powder, that is, if there has been too much powder admitted. At station 11, there is an inspection to determine if there is too li ht a charge of powder. At station 12, the ullet is inserted in the shell. At station 13, there is inspection to determine the presence of a bullet. Station 14 is a dwell station for a normal cartridge and an ejecting station for an imperfect cartrid e. At station 15, of the cartridge has wit stood the several inspections, the bullet is driven home to its final osition. eartri ge continues its movement and is dischar ed into a receptacle conveniently locate to receive it attheright of the machine. 1

The operation of each'of-the' inspecting mechanisms'is substantially the same, but

for'the pur ose of illustration, will particularly descri e the slide 34 and its associated parts, that is, the inspectingslide for deter- .mining whether the charge of powder in the cartridge shell is too light.

Adjustably fizted to the face of each of these inspecting slides is a stop plate 62,

which is provided near its lower "end with Thereafter, the completed an opening 63, the lower wall of which forms a stop shoulder 64. Movably mounted within the slide is a plunger 65, which is encircled by a spring 66 to move the plunger in one direction relatively to and independently of the slide. The upper end of this plunger is formed with a head portion 67 that is within the opening 63, being of considerably smaller area in cross section, than the opening and fixed therein is a cam pin 68.

Pivotally mounted upon the stop plate 62 by the screw 69 is the trip plate 70 provided with a cam 71 thereon, which is held in contact with the pin 68 by the spring 72, which is connected at one end to the stop plate 62 and at the other end to the trip plate 70 by the pin 73.

Movement of the head portion 67 on the plunger 65, parallel to the length of the slide causes the lower end of the trip plate 70 to swing to the right or left upon its pivot mounting according to the direction of movement of the head portion 67.

The plunger 65 is flattened at 74 and by its engagement with the walls of the stop plate 62 between which it passes is held against rotation.

In Figure 4 is illustrated a portion of this slide 34 at the extreme upper end of its stroke, at which time the inspecting plug 80 is in its up position and the under-side of the head portion 67 is in contact with the stop shoulders 64 and spring 66 is compressed.

The outer end of the throw over lever 78 is supported in the notch in trip lever arm '77 and the end of the arm 79 is out of the path of movement of the trip plate 70.

lnFigure 5 the parts are shown when the plug 80 is resting 'on a normal charge of powder in the cartridge shell, the'slide 34 being in its down position. When thus positioned, the head 67 on the plunger is out of contact with the stop shoulders 64, the trip lever arm 79 is out of the path of movement of the trip plate and the throw over lever is still supported by the trip lever 76. In Figure 6 some of the parts are shown in the relative positions occupied by them when the charge of powder in the cartridge shell is too light, the head 67 being in contact with the stop shoulders 64, because the stop plug has moved farther into the cartridge shell. Thus the trip plate 70 contacts with the trip lever arm 79, rocking the trip lever and releasing it from the throw over lever 78, which in turn is moved upon its pivot mounting 81 by the spring 82. These throw over levers are each supported upon the bracket 99.

Upon each of the slides 33, 34 and 36, is a lifter plate 83, having a finger 84 thereon that projects laterally into the path of the outer end of the throw over lever 78. At the next upward movement of the slide, after the throw over lever 78 has been released,

the finger 84 contacts with the throw over lever and lifts it 'to a position substantially as shown in Figure 4, where it is again engaged-by the trip lever 76 and held in its up position.

The trip plate 70 connected with the slide 33 "differs from those connected with the other slides only in that the cam 71 thereon contacts with the underside of the cam pin 68 instead of the top side. This is requisite because the stop plug 115 which inspects for on the worm, near one end thereof, is a lifter wheel 89 having a cam groove in its inner face. This cam groove begins at the face of the wheel, extends about one-half the distance around the face, gradually increasing in depth, terminating at a pocket 116, that is substantially the same diameter and depth as the balls 96.

The bottom of the cam groove at its junction with the wall of the pocket 116 iscut away to form an inclined face 94 to facilitate the passage of the balls from the pocket into the cam groove. wall of the pocket is inclined to facilitate entrance of the balls thereto.

Substantially parallel with the bracket 85 is a runway 93 for the balls 96, one end of which is adjacent to the annular groove 92, and the other adjacent to the inner face of the lifter wheel 89 opposite the path of the cam groove 90 therein.

The pitch of the helical groove 91 is substantially the same as the distance between the centers of the slides 33, 34, 35 and 36, and within said groove are the balls 96. During the rotation of the worm, these balls travel in a straight path on the left of the center thereof, as shown in Figure 3, riding against the face 97. After they have traveled the length of the worm they enter the annular groove 92 and fall therefrom onto and over the runway 93 and drop into the pocket 116 and by the rotation thereof are carried in the cam groove into the helical groove 91, at the next rotation'thereof, being guided in this movement by the yoke 98,

Likewise the inner the open space thereinbeing substantially the same diameter as the balls 96. Theseball 96 is in front of the arm 101 of each of the throw over levers 78 at each'down stroke of the slides 33, 34 and 36. If any one of these levers is rocked in the manner above any subsequent throw over levers.

J ournaled upon a stud 104 in the bracket 'cap 100 is the lever 105, having a cam lug 106 at the outer end thereof, which is in theath of movement of the balls 96 when ridlng against the face 103.

Fixed to a portion of the carrier mechanism 29, supportedrupon the holster plate 107, is a bracket 108, with which is connected a slide 109, that is moved in one direction by a spring 110. J ournaled in the bracket 108 is a rock lever 111, one arm of whichprovjects into an opening in the slide 109 and the other end is connected by a rod 112 with the lever 105. v

At all of the stations, except station 14, the lower edge of the cartridge shell, while traveling through the machine, rides upon a fixed shelf 113, but at station 14 it rides upon the inner end of the slide 109 and travels thereover in substantiall a straight path, if the shell has been foun normal, at each of the inspecting stations. If, however, at any one of the inspecting stations it has not withstood the inspection test, the adjacent throw over lever 78 is rocked upon its mounting and the ball 96 adjacent to the end of the arm 101 thereon is moved over to the position shown by broken lines 102 in Figure 3, and while thereafter traveling in this position, it is moved under the cam lug 106 on the lever 105. This causes the lever 105 to rock upon its pivot mounting, lift the rod 112,

actuate the rock lever 111, and by reason thereof withdraw the slide-109 from underneath the cartridge. There now being no support for the defective cartridge it drops through the opening 114 into a receptacle conveniently arranged to receive it. The last mentioned-ball, after actuating the lever 105, continues its movement, falls into the annular groove 92 and is returned to the other end of the worm to be reused in the manner above described.

After the member 109 has moved to' its outward position to ermit the escape of a defectivecartridge, t e same is returned to its former position "by the spring 110 and this assists gravityin returning the lever 105 to its position, substantially as shown in 'Fi ures 7 and 8, to be actuated by another ha I, if dperchance a defective cartridge is inspecte B this mechanism, the defective cartrid e is e ected from the machine when found aulty at a station, and without notice to the operator of the machine and without stop ing the same.

T e bullet is lightly inserted in the cart-' 7 ridge shell at station 12, so that if ejected at station 14 it can be readily removed and a charge of owder therein released, but if the cartridge is perfect, the shell is resented to tools at station- 15 thatdrive the ullet home and secures .the same in its permanent position. By thus arranging to insert the bullet lightly at this point, no powder escapes from the shell if the same is found defective.

There are minor changes and alterations that may be made within my invention, aside from those herein suggested, and I would therefore have it understood, that I do not limit myself to the exact construction herein shownand described,. but claim all that falls fair(l1y within the spirit and scope of the appen ed claims.
