Serial No. 771,487.

To all whom it may concern:

Be it known that I, WALTER J. LOWRY, a citizen of the United States, and a resident of Waco, in the county of McLennan and State of Texas, have made certain new and useful Improvements in Cake-Cloth Removers and Truck-Loaders, of which the following is a specification.

My invention is an improvement in cake cloth removers and truck loaders, and has for its object to provide mechanism of the character specified, having means for mechanically removing the press cloth from cotton and linseed cakes, and for afterward delivering the cakes to other mechanism for loading the same on a truck or the like.

In the drawings: Figure 1 is a side view of the improved mechanism, Fig. 2 is a top plan view, Fig. 3 is a rear end view, Fig. 4 is a partial front view, Fig. 5 is a section on the line 55 of Fig. 2, Fig. 6 is an enlarged sectional view of the receiving mechanism for the cake, Fig. 7 is a section on the line 77 of Fig. 6, and, Fig. 8 is a perspective view of an oil cake with the press cloth in place.

Before pressing the meats of cotton seed and the like, they must first be wrapped in cloth, called press cloth, then placed in a press, for removing oil. Where a considerable compression is necessary to remove the oil or other substances, the meats are left, after pressing, in the form of a hard boardlike body, and before being loaded,the cloth must be removed.

The present embodiment of the invention comprises a frame consisting of uprights 1, and standards 2, connected by upper longitudinal bars 3 and lower longitudinal bars 4. The uprights are connected by a top A bearing 6 is arranged transversely on each standard 2 at the front thereof, and above the longitudinal bars' 3, and a shaft 7 is journaled transversely of the standards in the bearings.

A hanger 8 suspends from the shaft at the center thereof, and a rod 9 has one of its ends passing through the hanger and engaged by nuts 10 on each side of the hanger. The said rod extends forwardly through a tube or sleeve 11, and the said sleeve is seated in bearings in bridge bars 12 arranged transversely of the bars 3, and supported at their ends by abutments 13 which rest upon a table 1.4 supported by the bars 3, before mentioned. The said table 14 is extended beyond the bars 3 at one side of the machine, as indicated at 14, and the extension is supported by uprights 15.

The tube or sleeve 11 extends beyond the outermost bridge bar 12, and a filling block 16 is arranged in the said tube near its outer end, the said block having an opening through which the rod 9 extends. The outer end of the tube 11 is open at its top and at its outer end, forming thus a trough-like mouth. An angle bar is arranged at the said mouth, the said angle bar consisting of a portion 17 extending toward the end of the mouth, and a portion 17 arranged at approximately a right angle to the portion 17.

The portion 17 has an extension 18 forming with the portion 17' a fork, and the angle bar is pivoted between the arms 19 of a yoke at the junction of the arms of the fork, as indicated at 20. A coil spring 21 is connected at one end to the free end of the fork and at the other to the tube, the said spring acting normally to hold the angle bar in the position of Fig. 6. The body 19 of the yoke encircles the tube, just beyond the filling block 16, and guide arms 21 are connected with the pivot bolt 20 inside the arms 19 of the yoke, and the said arms 21 extend forwardly and downwardly inside the open mouth of the tube.

The guide arms are spaced apart just sufiiciently'to permit the free movement of the angle bar, while at thesame time they prevent any lateral movement thereof. The said Walls of the tube are extended at the yoke 1919 as indicated at 22, the said extensions being parallel, as shown. A coil spring 23 is connected with the free end of the arm-18 of the fork at one end of the spring, and at the other end to the tube 11. The said spring cooperates with the'spring 21, to hold the parts in the position shown in Fig. 6.

A guide frame 24 is arranged transversely of the table just in front of the yoke 19-19-, and the said tube 11 extends through the frame at the front thereof. A foot or treadle lever 25 is secured at its rear end to a shaft 26 supported by the frame, and the free end of the said lever extends beyond the front of the frame.

A link 27 connects the lever near its front end with a radial arm 28 on a shaft 29 journaled on the uprights 1, and the said shaft is provided with a pair of rearwardly extending arms 30, whose free ends engage the lower ends of rods 31, each rod having a head 32 at its upper end engaging beneath a movable section 33 of the table 14. Each rod moves through a guide opening in a cross bar 34 near its upper end, and it will be evident that when the shaft 29 is rocked in the proper direction the section 33 of the table will be lifted.

A. flexible member 35, a cord or the like, has one of its ends connected with the lever 25, and the other with one end of a coil spring 36, the said member passing over a pulley 37 intermediate its ends. A cord or rod 38 connects the other end of the spring with one of the standards 2. A lever 39 is pivoted to the top 14 at its upper end, as indicated at 40, and the lower end is connected with the flexible member 35. Intermediate its ends the lever is pivoted to the movable section 41 of a clutch, the said clutch being mounted to slide on a shaft 42 journaled in the supporting frame at its front end, and in a depending bracket 43 at its rear end.

The fixed section 44 of the clutch is secured to the shaft, and the said section is connected by a belt 45 with a pulley 46 on a countershaft 47 ournaled in bearing brackets 48 below the shaft 42 and parallel therewith. The said shaft 47 is provided at its rear end with a beveled gear wheel 49, meshing with a similar gear wheel 50 on a shaft 51 journaled transversely of the frame in bearings 52 supported on the bars 4.

The shaft 42 is provided with a pulley 53, and the said pulley is connected by means of a belt 54 with a pulley 55 secured to a countershaft 77 to be later described. The said shaft 77 is connected to the tube, by means of a belt 80 which connects a pulley 7 9 on the countershaft with a pulley 81 on the tube. The tube 11 may thus be rotated from the shaft 47, when the clutch 41-44 is properly arranged to rotate the shaft 42. The hanger 8 for the rod 9 is as before stated mounted on the shaft 7, and the said shaft is provided with a ratchet wheel 56 adjacent to the hanger. A pawl 57 is pivoted to the hanger and engages the ratchet wheel. A collar 58 is arranged on one side of the ratchet wheel, and held to the shaft by a set screw 59, and another collar 60 is arranged on the opposite side. The front end of the rod 9 is connected to the arm 17 of the angle bar, near its junction with the arm 17 It will be evident that when the said rod is moved longitudinally rearwardly, the angle bar will be swung in a direction to cause the portions 17 thereof to move toward the mouth of the tube.

Shafts

61 and 62 are journaled transversely of the frame in the bars 3, and each shaft is provided with a pair of spaced sprocket wheels 63, and the registering wheels of the-shafts are connected by end less chains 64. Each of the said chains is provided with lugs 65 for engaging the cake and moving the said cake on the table 14. The upper runs of the chain 64 are just above the top of the table, and the movable section 33 of the said table extends from one chain to the other, as will be evident from an inspection of Fig. 2. The shaft 51 is journaled directly below the shaft 62, and the said shaft is extended beyond the frame at the extension table 14 At one end the shaft 47 is provided with a pulley 70, which may be driven from a suitable source of power by means of a belt 71. The opposite end of the shaft 51 is provided with a pulley 72, connected by a belt 73 with a pulley 74 on the shaft 62. Outside the pulley 72, the said shaft 51 is provided with a sprocket wheel 75, connected by a sprocket chain 7 6 with an endless carrier to be described.

The before mentioned counter-shaft 77 is journaled on the extension table 14% in bearing brackets 78. The belt 54 passes through a framed opening 89 in the extension table 14, the said belt inclining inwardly toward the pulley 53 on the shaft 42.

The sprocket chain 76 before mentioned engages a sprocket wheel 90 on a shaft 91 journaled transversely of the standards 2 near their upper ends, in bearing brackets 92 secured to the said standards and extending rearwardly therefrom. Sprocket wheels 93 are secured to the shaft 91 in spaced relation, and the said wheels are connected by sprocket chains 94 with sprocket wheels 95-on stub shafts 96 journaled in slidable bearing blocks 97 in guide frames 98 secured to the supporting blocks 2f on the lower ends of the standards at the rear thereof.

Each of the sprocket wheels 95 is in register with a wheel 93 on the shaft 91, and the bearing blocks 97 are movable vertically in the guide frames, being adjustable therein by means of threaded rods 99 threaded through the upper ends of the frames and engaging the blocks. The tension of the chains 94 may thus be adjusted to suit conditions. Each of the said chains 94 is provided with a plurality of carriers. Each of the said carriers consists of a table 100 having outwardly extending laterally spaced arms 101. The said arms engage opposite sides of weights 102, and are connected to the weight by means of a bolt or rivet 103, the said bolt or rivet passing through the arms and the weight.

The weights are connected to the chains by bolts or rivets 104, and the said tables are mounted to swing upwardly, to release the cak carried by two of the said carriers. The carriers of the two chains are in register, and each cake is carried between the chains, being engaged by a table at each chain. The truck to be loaded, indicated generally at 105, is pushed between the chains, as indicated in Figs. 1 and 2, and the cakes are placed in a superposed position on the truck.

Each of the weights 102 is provided with a stop pin 106 for engagement by the table to hold the same in engaging position. Each of the said tables inclines upwardly toward its inner free end, as indicated in Fig. 3, and the cake indicated at 108 in the said figure is supported on the said free edges' of the tables.

The operation of the device is as follows: The cake 108, as shown in Fig. 8, is covered on its two faces and at its ends by the press cloth, the said cloth indicated at 109, being in the form of a strip having its ends at the middle line of oneface of the cake. The cake from which the cloth is to be removed is placed on the movable section 33 of the table, the said section being at this time in the position shown in Fig. 5. One of the ends of the cloth is separated from the cake, as indicated in dotted lines in Fig. 8, and the free edge of the said end is placed in the mouth of the tube, after which the treadle lever 25 is depressed by the foot of the operator.

The shaft 29 before mentioned has an upstanding arm 110, and the said arm is connected by means of a link 111 with one of the arms 112 of an elbow lever pivoted at 113 to one of the standards. The other arm 114 of the said lever is connected by means of the link 115 with an arm 116 extending rearwardly from the shaft 7 When the said treadle lever is depressed as stated, the shaft 29 is rocked to move the links 111 to ward the front of the table. The cake to be stripped is laid on the movable section 33 of the table. When the treadle lever 25 is moved downwardly, the movable section of the table is raised, to bring the cake near the free end of the tube 11. Th said movement of the treadle lever causes the elbow lever 112114 to move to cause the arm 116 to oscillate the shaft 7 to move the rod 9 rearwardly, and the said rod swings the portion 17 of the angle bar downwardly, to cause the lower face thereof to engage the bottom of the mouth of the trough, thus clamping the free end of the press cloth to the tube. The same movement of the treadle lever moves the clutch section 41 toward the clutch section 44, thus connecting the shaft 42 with the power shaft 47, and the tube 11 is rotated from the said shaft 42. The rotation of the tube 11 winds the cloth around the tube, stripping it from the cake, and when the cake has been .cleared from the cloth, it will drop upon the movable section 33 of the table. The rod 9 is rotatable in the hanger 8, so that the said hanger does not interfere with the rotation of the tube.

After the cloth has been stripped from the cake the treadle lever 25 is released and the spring 36 will move the said lever upwardly returning theparts to their original position. The shaft 42 is now released from the driving shaft, and the rotation of the tube 11 ceases. The operator removes the cloth from the tube, after which the

springs

21 and 23 will return the parts to their original position. The cloth is easily removed for the free end of the tube 11 is tapering, as shown, to permit the easy removal of the cloth. After the cake has been released from the cloth, it will drop down upon the carrying chains 64, the said chains being spaced apart a lesser distance than the length of the cake. The lugs 65 on the chains will engage the rear edge of the cake, and as the chains move rearwardly the cake will be carried therewith.

As soon as the foot or treadle lever 25 is released, the movable section 33 of the table top will return to its lower position, as shown in Fig. 5. The endless carrier comprising the chains 64 is moving continuously, the upper run traveling toward the standards 2. The lugs 65 engage the rear of the oil cakes at the sides thereof, and move the said cakes rearwardly, finally depositing them upon receiving bracket arms 117, connected to the table 14 between the standards, the said arms extending rearwardly between the front runs of the chains 94. The said arms have their free ends inclined upwardly, as shown at 118, and the cakes are held by th arms until they are engaged by the tables 100. The front runs of the chains 94 are moving upwardly, and the tables 100 stand normally in the position shown in Fig. 3. The said tables engage the ends of the cakes, removing them from the bracket arms and carry them upward over the shaft 91, between the wheels 93, and then downwardly on the rear runs of the chains. The truck 105 is placed between the rear runs of the chains 108, and as the oil cake moves downward supported by the tables 100, it is finally deposited upon the top of the pile of oil cakes (Fig. 1). The tables may swing freely upward at their outer edges, and they are so swung by the ends of the cakes already deposited, or by the truck at the commencement of a pile, thus depositing the cakes in superposed relation on the truck. By means of the truck they may be carted away to the place of storage or deposit.

The rod 9 may be moved freely in a forward direction to open the tongue 17, that is a portion 17 of the elbow lever 17 17 18. hen the treadle lever 25 is moved downwardly at its free end, the link 11 is moved forwardly, thus moving the link 115 upwardly. The arm 116 is swung upwardly, and as the ratchet wheel 56 is rigid with the &

move the rod 9 in a direction to close the tongue 17. When the treadle lever is released, the spring 36 will lift the free ends of the said lever, moving the link 115 downwardly, and permitting the parts to return to their normal position. The pawl 57 engages at all times the same tooth of the ratchet wheel. Retarding fingers 119 are pivoted on the forward brie ge bar 12 and suspend therefrom, the said fingers being capable of swinging movement rearwardly at their lower ends, but being normally held in vertical position by coil springs 120. The said fingers engage the front edge of the cake to straighten the cake, in order that it may be properly engaged by the lugs 65. Mechanism is also provided for straightening the cakes as they are deposited in piles on the truck. The said mechanism comprises fingers 121, the fingers being connected to the chains between the tables. Each of the said fingers incline inwardly and upwardly, far enough to engage the end of the oil cake after it has been deposited on the pile, and the said fingers sweep down along the adjacent ends of the pile, straightening the topmost cake, and bringing its end into alinement with the ends of the pile.

It will be understood that the tables 1.00 are curved, as shown in Fig. 3, the convex faces of the tables being upward. The angle bar 1'T1'4', is formed from material cir' cular in cross section, and the portion 1? thereof is flattened, to permit the openings to be easily formed, and to permit the same to be arranged between the brackets. The portion 17, however, as will be seen from an inspection of Fig. 7, is circular in cross section, in order that there may be no projecting corners, and that it may fit smoothly in the trough of the tube.

The lever 25 is connected at its rear end to a shaft 26 which is journaled in bearings 25 on the uprights 2. The hanger 8 is in fact a pawl arm, carrying the pawl 57, which by its engagement with the ratchet wheel 56 causes the rod 9 to move rearwardly, when the free end of the lever 25 is depressed.
