Application filed. October 14, 1907. Serial No. 397,301.

To all whom it may concern:

Be it known that 1, JAMES A. KEYEs, a citizen of the United States, and resident of the city, county, and State of New York, have made certain new and useful Inventions Relating to Presses, of which the following is a specification, taken in connection with the accompanying drawings, which form a part of the same.

This invention relates to presses and relates especially to power presses for the production of cakes of soap or other articles.

In the accompanying drawings showing an illustrative embodiment of this invention, and in which the same reference numeral refers to similar parts in the several figures, Figure 1 is a plan view. Fig. 2 is a longitudinal section taken along the line 22 of Fig. 1. Fig. 3 is an enlarged top view partly in section showing the dies and die plunger. Fig. 4 is a similarly enlarged view showing the parts in a different position. Fig. 5 is an enlarged side view showing the feeder grips. Fig. 6 shows the finished soap cake. Fig. 7 is a detail showing the. spring detent. Figs. 8, 9 and 10 are enlarged views showing the feeder in different positions.

In the illustrative embodiment of this invention shown in the drawings, the heavy frame for the operating parts of the machine may be formed by the members 1, 2 connected by suitable transverse braces and having bearings 5, 6, in which the drive shaft 4 having the pulley 3 thereon may be mounted. The bevel gears 9, l0 drive the cam shaft 12 from the drive shaft, this cam shaft being mounted in suitable bearings 11 on the frame and carrying the cams 13, 15, as well as the pulley 120 which operates the discharge belt 121. The table 95 may be provided with suitable adjustable guides 88, 90 and with an aliner 122 by which the articles may be properly fed in connec tion with the supply belt 89, if desired. This belt is mounted on a loose pulley 92 on the shaft or connector 93 and is driven by the pulley 91 mounted on the stub shaft 101 and driven by a sprocket chain 99 from the intermediate shaft 123 which carries the spur gear 98 meshing drive shaft 4.

The articles fed into the press against the aliner 122 may be fed along to the dies or other compressing apparatus by a suitable feeder 23 which may be mounted in bearings 26 at one side of the machine and in the bearwith the gear 97 on the ing 100 supported in the bracket 96 at the other side. This feeder may be given a reciprocating movement by the link connected with the collar 29 on the feeder and pivoted at its other end to the lever 14 having a suitable follower 125 to engage a cam groove in the face cam 13. It is also preferably given an oscillating movement at the same time by forming the feeder end 24 polygonal to properly engage the sleeve 28 aving a suitable collar 27 between the two bearings 26. The arm 25 on this sleeve 28 may carry a suitable follower 124 to cooperate with a cam groove in the cam 15 so that the feeder arms 20, 21 adjustably secured on this feeder may be raised by oscillating the feeder, then reciprocated rearward, then swung down to engage a blank and reciprocate with the same forward to bring the blank into codperation with the dies. The detacher 103 may also be adjustably mounted on a similar arm 102 on the feeder, as indicated in Figs. 1 and 8.

The feeder arms 20, 21 may be formed as indicated in Figs. 8, 9 and 10 and com rise suitable pins 67, 68 to which the heats 22 carrying the grips 69, 70 are secured, for instance by the projecting studs 71, 72. A suitable spring 111 may be used to force the grip 7O inward and this spring may be secured to the collar 110 on the pin 68, and at its other end to a suitable detent sleeve 112 which cooperates with a detent 113 mounted in the arm so as to cause the desired intensity of spring action. The lever 109 is mounted on the inner end of the pin 68 and its upper end 31 co6perates with a suitable adjustable stop 108, as seen in Fig. 9. This lever engages at its lower end the cam 96 so that during the rearward movement of the feeder the lever and grip 70 are swung upward away from the corresponding grip, as 69. When the feeder comes into its extreme rear position as in Fig. 8, it is oscillated so that the grips swing downward on either side of the article 62 and then when the feeder again moves forward the lever rides over the projecting end of the cam 96 so as to gradually swing downward and engage the forward end of the article, force it rearward against the grip 69 and grip it in connection therewith.

As indicated in Fig. 1, the drive shaft 4 may carry two cams 7, 8 in opposite phase to actuate the connectors 104, 104, which as indicated in Fig. 2, are pivoted to the lugs 106, 107 on the two slides 18, 19. The slide 19 may be formed with the slide head 75 to which is secured the plunger 76 carrying in its forward end the die 64, which of course, may have a working face of any desired shape. The releasers 73, 74 having downwardly inclined cam faces may be mounted on either side of this slide head so as to engage the studs 72 and swing the grips apart out of engagement with the blank as the slide moves forward, see Figs. 1 and 2. A cylindrical ejector 63 may be mounted within the die and plunger and normally pressed forward by a spring 85 acting between the bracket 87 and the set nuts 84 on the ejector, as indicated in Fig. 1. A suitable aliner 86 in this bracket cooperates with the end of the plunger 63 so as to properly aline its forward end with respect to the die 64. The detent 83 may be pivoted in the frame so that its end cooperates with the collar 126 on the ejector, as is seen in Fig. 1. The other end of this detent is engaged by a suitable strong spring 79 mounted in the bracket 81 and operating to force the end of the detent against the adj ustable sto 77 mounted in the lug 78. The slide 18 may be provided with the slide head 65 to which the die casing 34 may be secured in any desired way as by the bolts 66. The plunger 35, to the outer end of which the rear die 33 may be secured, asses through the slide head and also throug the slide yoke 40 secured to the slide, the fork 39 being secured to the plunger to the rear of this slide yoke. The ends 41 of this fork cooperate with the adjustable stops 42 mounted in brackets 44 secured to the machine frame and rigidly held in adjusted position by the set nuts 43. In this way, the forward movement of the lunger and rear die 33 is positively limite The plunger 35 is normally pressed forward by spring action which may involve the primary spring 37 operating be tween a suitable adjustable abutment 36 on the plunger and the forward end of the slide yoke. At the time when the final compres sion takes place a secondary spring may also be brought into operation, if desired, by using the spring sleeve 45 which, as indicated in Fig. 1 may be mounted loosely within the slide collar 48 secured to the slide 18 below. The forward movement of this spring sleeve may be limited by the ring 46 and the secondary spring 47 engages and presses this spring sleeve forward, the annular collar stop 48 being adjustable within the collar to secure the proper intensity of this spring action. A similar cylindrical ejector 32 may be mounted within the plunger 35 and provided with the set nuts 50 on its rear end to limit its forward motion with respect to the plunger. Its extreme rearward movement with respect to the plunger may be accurately limited by the adjustable aliner 41 mounted in the enlargement 49 of the plunger soas to properly cooperate with the lug 53 secured to the ejector which is normally pressed forward by the spring 52 acting on this lug. The detent 54, Figs. 3 and 7, cooperates with this lug to retract the ejector overcoming the spring 52 which normally tends to protrude it. This detent may be mounted on the stud 61 in the frame and normally pressed toward the lug by a suitable spring 60 having one end engaging the detent and the other end secured to the pivoted spring clip 59 which is engaged by a suitable adjusting screw 58 to adjust the intensity of this spring action, which should be sufiicient to overcome the spring 52. The distance piece 56 is mounted on a suitable extension 57 of the slide and is adjustable so as to properly engage the tail 55 of the detent 54 so that the other end of the detent engages the lug 53 at the proper time.

During the operation of the press, the blanks 62 are engaged by the grips 69, at the proper time and fed forward while held between the grips so as to be brought accurately between the dies 33, 64. At that time, the slides approach each other and the ejectors come together, engaging the blank on either side so as to hold it between them, as is shown in Fig. 3, the inward movement of the ejectors being adjusted so as to give the desired intensity of this gripping action. Then the further movement of the slide 19 brings the releasers into engagement with the studs 71, 72 so as to wedge the studs upward and swing the connected grips apart away from the blank held by the ejectors so that the feeder may be swung up and moved backward to engage another article. Then as the slides move together still further the fork 39 may come into engagement with the stops 42, preventing further forward movement of the rear die '33. As the slide 19 moves forward from the position indicated in Figs. 1 and 3, the strong spring 79 causes the detent 83 engaging the collar 126 on the ejector 63 to overcome the action of the spring 85 and gradually force the ejector backward with respect to the plunger and die until when it comes into engagement with the aliner 86 this ejector is accurately flush with the die 64 as indicated in Fig. 4 and held accurately in that position. The forward movement of the slide 18 moves the distance piece 56 so that the detent 54 is swung around and retracts the lug 53 and the connected ejector 32 so that the outer end of this ejector is gradually withdrawn until it is brought and held accurately flush with the working face of the die 33, as is indicated in Fig. 4, and maintained in this position by the aliner 51 engaging the lug 53. The ejectors during these relative movements maintain their grip on the blank 62 and support the same symmetrically with respect to the dies.

The forwardmovement of the slide 18 carries the slide head and connected die casing 34 forward so as to inclose the blank 62 and when the two dies 33, 63 engage the blank the further movement of the die 64 presses the die 33 and its plunger backward against the action of the primary spring 37 so that the blank may be gradually and symmetrically expanded until its edges engage the die casing. At this point the secondary spring may be brought into action to increase the resistance to the further rearward movement of the rear die, the plunger abutment 36 coming into engag ment with the spring sleeve 45 at this time. A slight further movement of the 'front die 64 gives the final compression which completes the forming of the article, the parts then having the positions indicated in Fig. 4, this position being held while the eccentrics pass their dead centers. The slides thereupon move apart and the slide 1'9 and front die 64 are withdrawn, moving out of engagement with the die casing and the article, the springs pushing forward the plunger 35 and connected rear die 33 during this time until the rear die is in about the position indicated in Fig. 3. The ejector spring 52 is preferably so adjusted that the adhesion of the article to the face of the die 33 wher soap is acted on, is sufiicient to keep the ejector in its retracted position within the die so that its outer end is flush with the Working face of the same, as indicated in Fig. 4, until the die face is clear of the die casing. 'lhereupon the oscillation of the feeder 23 brings the detacher 103 sharply into engagement with the article, as is indicated in Fig. 8, freeing it from the die face. Then the ejector springs forward under the action of its protruding spring 52 so that the completed article is immediately forced away from the die face and can be moved along toward the discharge belt by the grip 70, the slide 18 having sufficient rearward movement, if desired, to carry the fork '39 clear of its stops and give ample clearance as the feeder brings forward a new blank between the ejectors.
