Application 'lled February 16. 1905. Serial No. 245,910-

To a/ZZ whom t may concern:

Be it known that I, EDWIN CARVER, a citizen of the United States, residing at Winchester, in the county of Randolph and State of Indiana, have invented certain new and useful Improvements in Machines for Making Plugs for Paper-Rolls, of which the following is a full, clear, and exact specification.

My invention comprises improved means for advancing the material to be operated on, improved means for boring out the center of the plugs and for forming the exterior of the plugs, as well as the means for severing the completed plugs from the source of supply.

Other objects and particular advantages of my machine will be made apparent in the course of the ensuing specification.

One manner of carrying out this invention `and that which in practice has been found to companying drawings, in which- Figure 1 is a plan view of my entire machine. Fig. 2 is a front elevation of the mai chine. Fig. 3 is a right-hand end view thereof.- Fig. 4 is a left-hand end view thereof.

Fig. 5 is a central longitudinal sectionof the machine'as taken on the line X X of Fig. 1. Fig. 6 is a cross-sectional view ofthe machine as takenon the line Y Y of Fig. 1. Fig. 7 is a detail view of the means for actuating the lateral movements of the bit and knives. Fig. 8 is a detail plan view` of same. Fig. 9 is a detail view oi the means for releasing the material during the time the machine is being fed forward and for holding it during the time it is `being acted on. Fig. 10 is a detail isometrical view of the product as formed and completed by the machine. Fig. 11 is a4 detail face view of the feed-operating cam. Fig. 12 is a detail showing an edge view of the feed-operating cam. Fig. 13 is a detail of one of the identical rollers for the ratchet, and Fig.v 14 is a detailview of the ratchetdisk.

Similar indices refer to and denote like parts throughout the various views of the five sheets of drawings.

In order that my invention and its intend- `ed operation may be more readily under- 4an especially-designed body or table A, having the perfectly level bed-plate a, and it is supported and carried on four legs Aand A anda and a, all of the other devices being carried by said parts and located substantially as shown in the drawings. Between the legsA and A is a web carrying the bearing B, and between the legs a and a is a web carrying the bearing C. Mounted longitudinally ofthe machine and carried in said bearings B and C is the main shaft D, on which shaft are mounted various cams and other parts, which will presently be explained. End movement of the shaft D is prevented by the two collars E and E', which are located adjoining the outer ends of the bearings B and C, respectively.

Forming mechanism--Mounted on the bed-plate a are the two standards 1 and 2, right and left, respectively, having mounted on their upper central portions the respective bearings 3 and 4, in which bearings the horizontal operating-shaft 5 is revolubly and slidably endwise mounted, and said shaft 5 extends across between said bearings and projects to the right and left thereof, as shown. Extending centrally and longitudinally through the shaft 5 in an axial direction is a circular aperture to receive therod,

loosely slidable therein. At the left-handl end of the shaft 5 the mouth of said aperture is enlarged, from which it tapers to the right convergingly and joins the uniform aperture, which extends the balance of the distance to the right-hand end of the shaft 5; Contained in said tapering portion of said aperture is a split clamp 7, having its right-hand end secured to the left-hand end of said rod 6. In the clamp 7 is a space formed in an axial direction to receive removably the bit 8. vSecured around the left end of the shaft 5 is the head 9 for carrying the detachable knives H and I. The said rod 6 is threaded on its projecting right-hand end to receive the nut 10, whereby the clamp 7 may `be drawn to the right to cause it to tightly clamp the bit 8 and by which the bit 8 is held in the position shown. Secured on the shaft 5, between the bearings 3 and 4, is the pulley 11, provided to receive an independent belt thereover, whereby it is connected to the power-pulley. (Not shown.) By the above it is apparent that the shaft 5, carrying the bit and the knives, may be revolved at the desired rate of speed. Mounted on the right- IOD 1 hand end of the shaft 5 is a collar 12, in which the shaft revolves and the purposes of which collar will presently appear. f

The numerals 13 and 13 denote each a rod which are of identical construction mounted for horizontal endwise movements, being carried in apertures formed in the end of the frame A to provide bearings and with their left-hand portions carried in bearings formed therefor in the spider 14, which spider is suspended between the sides of the body A.

The numeral 15 denotes the vertically-disposed standard pivoted at its upper end to the collar 12, then extending downward, dividing into two branches, each being secured by screws to the outer ends of the rods 13 and 13, substantially as shown.

Connecting the inner ends of the rods 13 and 13 is the spider 16, and extending down through the center of the spider 16 is the pivot-bolt 17, which carries revolubly thereon the roller 18. Mounted on the shaft D is a double cam composed of the right and left members J and K, respectively, and which are of substantially identical construction, and they are spaced apart sufficient to allow the roller 18 to pass therebetween. Mounted on the outer right-hand end of the shaft D is the power-pulley L, having an independent belt extending to a line-shaft pulley. (Not shown.) It will now be apparent that the formation of the cam J K is such that when the pulley L is revolved the said cam will alternately move the rods 13 and 13 to the right and left, and thereby the shaft 5 will also be carried to the right and left at each revolution of the pulley L, as a consequence operating the bit 8 and the knives H and I to the rightand left. v

Feed mechanismpLocated on the lefthand end of the bed-plate a is the feeding mechanism, which I will now specify. This consists first of a base-plate 20, adjustably mounted on the bed-plate by four adjusting and securing screws 21, 22, 23, and 24, whereby the base-plate 20 may be adjustably secured vertically to the height desired for varying conditions. Mounted on the plate 20 are the two hangers or standards 25 and 26, spaced apart and secured each by a pair of machine-screws 27 27 and 28 28, respectively. Thel center portion of the hangers 25 and 26 extend upward and downward with vertical guideways 19 and 29, respectively, formed therein, as shown. Mounted in the lower portions 0f the guideways 19 and 29 are the respective guide-blocks M and N, in and between which is mounted the shaft 30. The guide-blocks M and N and the shaft 30 are adjustable by the set-screws 31 31, which extend up from below. Central of the shaft 3() is the V-faced roller 32. Extending to the left from the center of the plate 2O is the finger 33, having its extreme left end curved upward and divided, with a V-faced roller 34 mounted therein, which roller is identical with and alined with the said roller 32.

Mounted in the upper portion of the guideways 19 4and 29 are the respective guideblocks O and P, (similar to the said guideblocks M and N,) in and between which is mounted the shaft 35. Mounted on the shaft 35 between the guide-blocks O and P, is the large V-faced feed-wheel 36, the V-face of which is knurled or serrated to produce a biting-surface therearou-nd, as indicated, and being oppositely disposed to the said rollers 32 and 34. Extending up to near the height of the said guideways 19 and 29 are the relatively long guide- screws 37 and 37 their lower ends being screwed into hangers 25 and 26, and each having a pair of nuts 38 and 38 in front, and 39 and 39 in rear, which are threaded on their upper ends. The numeral 40 denotes a lever having the forked extensions 40a and 4Gb, the free ends of which are given a quarter-twist with a slotted aperture in each endto receive the bolts 37 and 37', as shown, whereby the forks or arms 40a and 40b are loosely mounted between the respective pairs of nuts 38 38 and 39 39. The said forks 40a and 40b are adapted to rest on the inwardly-projecting portions of the guideblocks O and P, to which they are loosely held in contact by the respective guide- fingers 41 and 41, whereby it is apparent that the feed-wheel 36 may be raised and lowered by the operation of the lever 40. The pressure downward on the feed-wheel 36 maybe varied by means of the weight 42, which weight is adjustable along the length of the lever 40 and -is securable at the point desired.

Raw 'material-The material to be su plied to this machine for operation on shou d consist of any suitable lengths of timber, substantially square in cross-section, as is indicated in Fig. 4, where it is designated by the letter R, and said material is to be fed into the machine endwise from the left-hand end of the machine between the lower rollers 34 and 32 and under the upper feed-roller 36.

Operation of the feed-The next construction l will describe is the means for automatically feeding the material R into the machine, where itis to be operated on. Mounted permanently on the shaft 35, just forward of the guideway 29, is the barrel or drum 43, and neatly fitting the interior of the said barrel 43 and mounted Within the barrel revolubly on the shaft 35 is the disk 44, neatly filling the interior of the barrel. The said disk is held in place in the barrel by the nut 45, which is threaded on the end of the shaft 35, as shown in Fig. 2, and the said disk and the face of the barrel may be closed by a cap or plate 95, if desired. Said cap 0r plate 95 is removably screwed to disk 44 by screws, as shown, and held to the face of the barrel by nut 45, so as to inclose the disk 44. Cut into and out of the regular rondure of the periph- IOO IIO

25 connecting-rod 48.

iery of the disk 44 are the two tapering indentations S and S of identical size and form, which extend across the thickness of the disk 'l and are of substantially the contour shown. The indices 46 and 46 denote a pair of iden- \ti`ca'l plain rollers of same length as is the thickness of the disk 44 and of a diameter less than the larger end of said indentations S and j S and greater than the smaller end of same. 1o 'By the employment of the mechanism just described it will be seen that the disks 44 will be free to revolve to the right independent of the barrel 43 but when revolved to the left the rollers 46 and 46 will wedge between the small ends of the respective lndentations S zo wheel 36 in a direction such as to feed the material properly into the machine. Projecting out from near the periphery oi the face of the disk 44 is the crank-pin 47, on which is mounted the left-hand end of the Mounted on the front portion `of the end of the body A is a hangerblock 49, having a pivot T, on which is pivoted the lever 50, the upper half of which has a longitudinal slot'U therethrough, as shown in ,3o Fig. 2.

The numeral 51 denotes a bolt mounted in the right-hand end of the rod 48 and through the slot U, whereby the end of the rod 48 may be pivotally connected to the lever-arm 3 5 v50 at any point vertically within the limits of the slot U.

Mounted on the shaft D, over the pulley L and the right-hand end of the body A, is the cam 52, having a depression into its left-hand 4o face, on which face the roller 53 is adapted to travel. Said roller 53 is mounted on the lower' end of the lever 50 by the pivot-bolt 54. Ahelical compression-spring 55is mount- V ed to press out between the lower end of the lever 50 and the end of the body A, as shown i'n Fig. 2. It will now be apparent that as the shaft D is revolved, the roller 54 being kept in contact with the face of the cam 52 by the spring 55, as the roller 53 is caused to 5o move alternately to the right and left the upper end of the lever will be moved oppositely thereto and with a greater latitude, thus operating to turn the feed-wheel 36 step by step the proper distance at the proper 55 time, this being adjustable by means of the slot U, as shown.

MctericZ-cZamp.-The left-hand portions of the hangers 25 and 26 extend upward with the vertical guideways 56 and 57 formed 6o therein, respectively, as shown. Extending across with the ends carried in said guideways 56 and 57 is the clamp-bar 58, which has a central inverted-V-shaped notch to engage the material and having its ends pro- .turned forward at right angles thereto.

ject through `and beyond the guideways 56 and 57, with vertical eyes formed through said outer projections to receive the upper ends of the rods 59 and 60, which are secured in said eyes by a pair of lock-nuts, as shown. Said rods extend down and slide loosely through apertures formed in the ears 61 and 62, which project out from the left-hand corners of the plate 20. The lower end of the rods 59 and 60 are connected by the yoke 63, to which they are secured by lock-nuts, as above and as shown. Extending down from the center of the yoke 63 is the hanger 64, in which is mounted the roller 65. Mounted on the shaft D is the cam 66, around the peripheral face of which the roller 65 is adapted to travel and by which the clamp-bar 58 is raised and lowered'at the proper time to engage and release the material. The roller 65 is kept tightly in contact with the cam 66 and the clamp-bar 58 in contact with the ina-k terial by the two coil- springs 67 and 68, which surround the respective rods 59 and 60 and are seated against the ears 61 and 62, respectively, substantially as shown.

I ntermedt'a/ry material remmen-Secured centrally of and on top of the clamp-bar 58 is the flat spring 70, which curves to the left and then to the right, terminating some distance immediately below the center of the clamp-bar 5,8 and having a lterminal end adapted to at all times engage the upper corner of the material, which may be in the machine and from which it does not release by the movements of the clamp-bar 58, to which it is attached, as shown.

The sawing mechanism-Mounted hori- IOO zontally and having its front end secured to the rear of the bed-plate by two pairs of bolts 71a and 71b and extending rearward therefrom is the permanent stationary table 71 for supporting the saw-carriage. Slidably mounted on the table 71, and mounted only for forward and backward movements thereover, is the saw-carriage 72, (preferably mounted on frictionless bearings, not shown.) Rising from the said carriage is a pair of pedestalhangers 73 73 in which is revolubly mounted the saw-shaft 69 on which shaft the circular saw 74 is mounted, adjoining the outer face of the hanger 73, as indicated. Mounted on the shaft 69, between the hangers 73 and 734, is the belt-pulley 75, from which a belt may extend to its drive-pulley located directly above. In the permanent table 71 is a central longitudinal slot, through which pass the downwardly-extending arms 76 and 77, which arms are united at their lower terminals and terminate in a finger 7 8,which is The upper end of the arm 76 is secured to the carriage 72 by the bolts 7 6a and 76h, and the upper end of the arm 76 is secured to the carriage 72 by the bolts 7 7at and 77h. Mounted IIO on the shaft D is the side-faced channel-cam 80, and mounted on the end of the finger 7S is the side-mounted roller 79, which is adapted to travel in the channel 80, as shown, whereby as the cam revolves, the saw-carriage will be moved forward and backward at proper intervals. l

Product and refuse conceyers--The numeral 8l denotes a square and downwardly and thence rearwardly extending spout or conveyer for the finished product, which is carried forward and backward with and by the saw-carriage, which conducts the finished product to the rear of the machine. Said conveyer is secured to the finger 7 8, as shown, while a tie 81 connects its central portion rigidly parallel with the arm 76. The upper end of said conveyer, when the saw is drawn to the rear, is closed by the permanently-located cover SS-that is, when the saw is out of action. Secured to the front of the spout 81 is a downwardly and forwardly extending deflector 84 for the shavings and refuse which falls from the knives and bit to be defiected forward.

The product-The numeral 85 denotes the .finished product, which is clearly indicated in Fig. 10, and it is designed particularly for use in rolls of paper or the like; but as to the product I make no claim.

Operation-It will be noticed that power is applied to this machine at three independent points by the pulleys L, 11, and 75, the two former revolving to the right while the latter revolves to the left. The machine is therefore geared to accomplish three distinct and independent operations, which may follow each other in progressive and proper sequence, and, if desired, the operations may overlap each otherthat is to say, one operation may begin before the completion of the other. The three operations naturally consist in, first, the feeding of the material and holding it while it is being fed; second, the boring and cutting the plug, which includes the approach and the withdrawal of the knives and the bit to and from the material, and, third, the completing of the plug by sawing it from the supply, In the drawings the machine is illustrated during the firstnamed operation. As the shaft D continues to revolve, the contour of the cam 52 is such that the feed-wheel 36 will remain stationary and the contour of the cam 66 is such that the clamp-bar 58 will engage and hold lthe material in its advanced position, which would be with the end of the material advanced to near the point of the receded bit 8. At this point the cam J K will have revolved to the point that it gradually causes the bit to be forced into the center of the forward end of the material to form the central opening in the to be finished plug, at the same time the shaft 5 being continuously revolved to revolve said and 'also to revolve the knives whereby the periphery of the plug is formed, as shown. As the bit and knives complete their work, they are, by means of their cams, withdrawnto the right,iand during the last stage of the last-named operation the cam 80 will have revolved to the point where it will gradually, but swiftly, move the sawcarriage forward, whereby the teeth of the swiftly-revolving saw 7 4 will be brought into contact with the material at the point to which the plug 85 is completed, the same being the larger end thereof, whereby the plug will be completed and severed, falling down through the spout S1 to the rear of the machine, as when the plug is being formed the chips therefrom fall in front of the machine.

Having now fully shown and described my invention and the best means for its construction and operation to me known at this time, what I claim, and desire to secure by Letters Patent of the United States, is Y 1. In a machine for making plugs for paper-rolls, the combination with means for alternately lfeeding endwise and holding a rod, cutters shaping the end portionthereof and a reciprocating cutting-off tool arranged and timed to sever the portionso shaped, of a spout or receiver traveling with said cuttingoff tool and advancing to a position under-the portion being cut off to receive the same-and a fixed cover for said spout, to a position under which it returns in order to exclude the chips produced by the shaping-cutter, all substantially as shown and described.
