MAGAZINE MEGHANISM.

Specification of Letters Patent.

Patented J an. 8, 1918.

Original application filed January 3,1910, Serial No. 538,186. Iivided and this application filed June 13, 1910, Serial No. 566,468. Renewed October 23, 1317. Serizl No. 193,180.

To all whom it may concern:

Be it known that I, FRIEDERICH Mtirnnn, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Magazine Mechanism, of which the following is a specification.

This invention relates to magazine mechanism which can be used in divers ways, although it is of peculiar importance when employed in combination with or as part of a lathe such as shown in my copending application filed January 3, 1910, Serial No. 536,106, of which this present case is a division.

One of the primary purposes of the invention is the provision of magazine mechanism including a magazine and a stock or blank transferring device which have eflective means for accurately and precisely 0btaining various adjustments so as to adapt it to the stock being operated upon in the machine with which the magazine mechanism is associated. There are other features of novelty and advantage which with the foregoing will be set forth at length in the following description wherein I will outline in detail that form of embodiment of the invention which I have selected for illustration in the drawings accompanying and forming part of the present specification.

1 do not restrict myself to the disclosure made by said drawings and description, which is arovided to enable those skilled in the art to practice the invention. I may depart radically from said showing within the scope of my invention as expressed in the claims succeeding said description.

Referring to said drawings:

Figure 1 is a plan view partially in section of magazine mechanism involving my invention. Y

Fig. 2 is a sectional View on the line 2-:2 of Fig. 1. i

Fig. 3 is a front elevation of one side of the magazine. 1 1

Figs. 4. 5 and 6 are detail views in isometric projection.

L ke characers refer to like parts throughout the several figures.

The gazine mechanism embraces in its organization a magazine such as that deno 11 a gen a W y by 5 nd tran ferring device as that denoted in a general way by 6, the magazine being generally statlonary and the transferring device serving to carry or conduct a blank or equivalentdevice from the magazine to a desired point, for instance, between the centers of a lathe. the said stock transferring device being in the present case reciprocatory.

The different parts oflhe magazine 5 are sustained by suitable framing which may, as shown, consist of two standards or upr ghts as 7 which are normally stationary and which are connected in some suitable manner with the framing of the machine in connection with which the magazine is employed. As the two standards 7 are similar in construction, a detailed description of one will apply the other. I have shown fitted against the inner flat surface of said standard 7 a plate 10 and similarlyv fitted against said plate 10 is a substantially similar plate 11, said plates having longitudinally extending flan es or lips 13 and 14: at their forward sides which in the present case extend vertically in parallelism, the space between said flanges or lips constituting a run way or channel 15 to receive one end of the blanks which gravitate along the magazine, the other end of the blanks fitting a corresponding run way on the other side of said magazine. The fian 'es or lips 13 and 1; as will hereinafter appear, can be adjusted toward and from each other so as accurately to adopt the run way to the size of the work. By referring to Fig. 1 it will be clear that the magazine is provided with end walls which in the present construction areformed by the plates 10. These end walls cooperate with the side walls formed by the flanges 13 and let to form the respective runways.

In order that the plates may be adjusted toward and from each other as before men tioned, 1 preferably provide means whereby they can be moved longitudinally. While 1 do not limit myself to any one means for this purpose, that which will now be described is uite satisfactory.

The plates 10 and 11 are shown as having laterally extending lugs or ears 16 and 17 in superimposed relation, said lugs having elongated slots each designated by 18, the elongation of said slots being from front to rear of the magazine. Each standard 7'.

provided at its upper end with an outward extending head or projection 8 which is adapted to receive an adjusting screw 9 which extends through the aforesaid slots 18. I have shown pinned to the upper end of said screw 9 a knurled head 19, the lower end of which (acting as a shoulder bears against the upper surface of the car 17 while the lower car 16 bears against a col-' lar as on the screw 9. I provide in effect that these two cars or lugslG and 17 be snugly fitted between the two shoulders or confining faces of the screw, and it will be obvious that when said screw is run into or out of its seat, the two plates 10 and 11 are respectively lowered and raisedin unison.

- The plates 10 and 11 are shown having slots 21 and 22 disposed transversely or at right angles to each other and through these slots a bolt 28 is passed, said bolt being rigidly connected with the standards 7 and the nut 24: thereof being adapted to clamp said plates 10 and 11 in adjusted positions. When it becomes necessary to change the width of the run way or channel 15, the nut 24 is first loosened after which the plates are raised and lowered as may be demanded and after the adjustment is secured the nut 21 is tightened.

Owing to the described construction, it will be apparent that when said plates 10 and 11 are raised, the wallsor flanges 13 and 1% are caused to separate to widen the run way 15, while on the lowering of the plates, the two walls will be caused to approach to narrow said run way, the slots 18 freely permitting lateral movement of the two plates 10 and 11 as they are raised and lowered. During the adjustment of the run way, the center line thereof never varies; that is to say said center line is not moved forward or backward, although the size or the width of said'run wayis changed; this change however, is obtained by moving the said walls of the run way 15 simultaneously toward or simultaneously away from each other or by giving to'said walls the same amount of lateral movement. Then also it is apparent that the run way or channel at one side of the magazine can be adjusted independently of the other; \Vhile the work shown in the magazine is assumed to be cylindrical in form and of uniform diameter throughout its length, the run ways in this ends. It is, of course, not essential that thework be cylindrical in formyit might be square or polygonal incros -section.

Y Thelaterally enlarged or wide ned base or foot25 of each standard 7 supports for slid-' ing movement a plate 26 constituting part of the stock transferring device 6, said plate traveling longitudinally. In'the case offa lathe the movement of this plate will be transverse or crosswise of the bed thereof. The base 27 of this plate is made practically in dove tail form and one side thereof bears against an angular face on the lower portion of the standard 7, while an angular face on the gib 2S bears against the opposite side of said dove tail portion 27. Theplate 26 and a complemental plate supported by the other standard comprise the body portion ofthe stock or blank transferring device 6, and the two plates connected by a rod as 29 which extends through slots 30 in the two plates. To the said rod 29 are connected arms 31, only one of which is shown, which are oscillatory, being intermittently operated so as toimpart a reciprocatory movement to the stock transferring device, the latter on the forward movement thereof being adapted to transfer a blank from the magazine 5 to the desired place and on its back stroke returning for a new blank. The means for operating the stock transferring device forms no part of the present invention for which reason it is not necessary for me to describe, or illustrate it. It will be remembered that I have been describing the standard 7 and plate 26 supported thereby at one side of the magazine mechanism these being duplicated, as will be evident, at the opposite side of the said mechanism. I will now proceed further with the description of the plate 26' and its adjuncts.

Fitted against opposite sides of the plate 26 are plates 32 and 33 having oblique slots each designated by 34 to receive the bolt 35 rigidly supported by the intermediate plate 26 and having a nut 36 which constitutes a. simple means for clamping the plates normally to each other. From this it will be evident that theplates 32 and 33 are adjustable and this adjustment is utilized in the present case to vary the size of the blank or stock transferring receptacle 6. The central or intermediate plate 26 is shown supporting for oscillation two rockers each denoted by 37'which have substantial central, circular hearing or fulcrum portions38 fitted for rocking motion in circular seats in said intermediate plate 26, the latter being alsov slotted as shown at 39 in each case to permit of the swinging of said two levers or rockers 37 which it might; be stated present a suit-' able equalizing means between the two adjustable plates32 and 83. The rockers are shown provided at. their centers with outwardly extending pins or studs to which extend through matched guideslots 41 in the two side plates 32 and 33, it being understood that each rocker has two of such pins or studs -10. The terminals or opposite ends of the rockers or levers 87 are forkedflhe outer side plate '32 having pins 42 near its upper edge to fit the upper forks while the inner plate 33 has pins 43 near its lower edge to fit the two lower forks. It will be as sumed that the outer plate 32 is thrust down, the nut 36 having been loosened to permit this action. On the downward motion of said outer plate it is moved forward and at the same time the inner plate 33 will be elevated and moved rearward, the degrees of movement of the two plates being identical owing to the presence of the interposed equalizing mechanism and this movement is what is utilized in-the present case to regulate the size of the blank receiving pocket or aperture of the blank or stock transferring device 6. When the adjustment is obtained the nut 36 will be tightened. In the illustration given the pocket in the blank transferring device will be narrowed while if the operation be reversed, the opposite result will occur, as will lereinafter more particularly appear.

The inner plate 33 has a substantially right angular cut away portion or rabbet 44 at its front end which forms part of a pocket or aperture 45 for receiving the blank to be transferred said blank dropping from the run way 15 of the magazine. A detent or latch 46 of substantially right angular shape is pivoted at its approximatelv horizontal branch as at 47 to the reduced forward portion of said inner plate 33, the pocket or aperture 45 in which the blank is received has a bottom and two sides, the bottom consisting of the bottom of the cut away portion or rabbet 44, the inner wall being the front edge of the outer plate 32 and the forward wall being the inner side of the vertical branch of the detent or latch 46. This latch is normally held in operative relation by a spring 48 coiled about the pivot 47, said latch at such time bearing against the stop pin 49 on the inner plate 33.

The blank transferring device 6 when in blank receiving position has the two pockets or apertures 45 in vertical alinement with the respective run ways 15 so that there will be nothing to prevent the gravitation of the lowermost blank in the magazine into the apertures or pockets. Clearly when the transferring device is in the position shown the bottom of the aperture forms a bottom wall for the runway. It will be assumed that a blank is in the twoseats or pertures of said blank transferring device and that the latter has just commenced to advance to transfer said blank. When the transferring device is moved forward the outer plates 32 will be under the lower open ends of the two run ways to stop the descent of the blanks. When the blank transferred has.

been positioned, said blank transferring device will be draw-n back and during this motion, the latches 46 will automatically recede or be tripped and thereby freed from the blank. In the case of a lathe, the centered blank which, of course, is clamped in position between the centers is utilized to trip the two latches simultaneously. The instant that the latches are freed from the blank thus centered, they are at once returned to their original positions by the springs 48. It will be understood that the blank receiving aperture 45 at one side of the transferring device can be adjusted independently of the other. When the transferring device is in its retracted position the latches 46 will be supported against lugs 50 on the gibs 28 so that the weight of the pile or stack of blanks is thereby taken from said latches. Inasmuch as the upper edge of the plate 32 engages the bottom edge of the plate 11, either of these plates can be ad justed first and then used as a gage for the adjustment of the other. In this way it is possible for the operator to adjust the aperture in the transferring device to the proper size and then correspondingly adjust the runway; or it is possible for him to first adjust the runway to the proper size and then correspondingly adjust the aperture.v

Either device serves as a gage for the adjustment of the other and in either case the center of the aperture, when in blank receiving position, is coincident with the central plane of the runway. Preferably the aperture is adjusted first by properly moving the plates 32 and 33 and then the runway is adjusted by moving the plates 10 and 11 downward until the plate 11 engages the plate 32.

It will be observed that there is a definite relation between the vertical adjustment of the plate 11 and the vertical adjustment of the bottom wall of the aperture. Inasmuch as the plate 11 is adjusted vertically to the same extent that it is adjusted horizontally,

it therefore follows that the vertical adjustment of the bottom of the aperture is also the same in extent as the horizontal adjustment of the plate. Thus the bottom of the aperture, which in effect forms the bottom of the runway, is moved to the same extent as the side walls of the runway, thus maintaining the axis of a fitting blank in fixed position.

This vertical adjustment of the bottom them that they are moved to the same extent relative to such line.
