MACHINE FOR ATTACH'NG SLATS TO C(FNVEYER-BELTS.

Specification of Letters Patent. 7

Patented Sept. 1 1, 1906.

T0 all whom it may concern.-

Be it known that I, WALTER T. GORDON, a citizen of the United States, residing at Juniper, in the county of Umatilla and State of Oregon, have invented certain new and useful lmprovements in Machines for Attaching Slats to Conveyer-Belts and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to a novel machine adapted for use in the manufacture of conveyer-belts for harvesting machinery, grainhandling machinery, and the like and comprising a continuous belt or belts and slats aflixed transversely thereto; and the invention refers more specifically to a machine for fastening the slats or other attached arts of a conveyor to the belt or belts thereo Such other parts mentioned may be-the belt-protecting disks located between the slats of the conveyor. The belt or belts referred to may consist of a wide web of canvas, two or more parillel separated belts, or a combination of bot Other analogous uses for such machine may be found, and the invention is not limited strictly to the specific use here suggested.

' The machine shown, in which is embodied my invention, comprises in general terms an anvil in which are formed openings carrying setting-punches (constituting movable parts of the anvil to facilitate feeding the rivets to the work) and arranged to receive the rivets at the outer ends of the'punches, which rivets are thereafter advanced to the Work by the punches, a rotating cylinder above the anvil between which and the anvil the work is to be passed and provided on its outer cylindric surface with a plurality of pockets adapted to receive the parts to be attachedto the conveyer or other part and to carry the same by the rotation of the cylinder to the work between the cylinder and anvil, a riveting punch orpunches carried, preferably, by the cylinder reciprocating through said pockets and coacting with the setting punch or punches, means acting on the settingpunches for setting the rivets or thrusting them through thework, and means acting on the riveting punch or punches to upset said rivets after they have been set. The c linder is given intermittent rotation to fee the parts to be riveted to the work, which are received by said pockets upon .the top of the work, and for arresting the cylinder with one set of riveting-punches in alinement or register with the setting-punches. When the parts to be riveted to the work are slats, they are riveted at the ends thereof or at the sides of the conveyer, so that in this event an operating set of riveting-punches embraces one punch at each end of the cylinder which cooperate with two like disposed settingpunches. If the slats are to be riveted at their longitudinal centers, an intermediate set of riveting and setting punches will be provided. Preferably, and as herein shown, the anvil has the form of a cylinder made of the same diameter as the riveting-punch-carrying and slat-delivering cylinder, and the cylindric .rotative anvil is provided ateach end with an annular series of openings in which operate the setting-punches referred to and which constitute movable parts of the anvil. Said setting-punches are normally retracted inwardly beyond the cylindric surface of the anvil as to constitute at the outer ends of the openings pockets to receive the rivets and by which they are thus delivered by the rotation of the anvil in line with the riveting-punches and pockets of the cylinder, to be thereafter thrust through the work preparatory to the upsetting operation.

I have herein shown my machine as designed to thus fasten a slat to conveyor-belts by means of fastening devices made in accordance with my prior United States patent, No. 704,823, granted on the 15th day of July, 1902, and when employing the fastening devices shown in said patent the constructionof the parts of the machine is varied from a machine designed to fasten the slats by the use of other forms of rivet-andwasher fastening devices.

i The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings, Figure 1. is a front elevation, with parts shown in section, of a machine embodying my invention. Fig. 2 is an end elevation thereof. Fig. 3 is a vertical sectiontaken on line 3 8 of Fig. 1. Fig. 4 is a detail showing the mechanism for intermittently moving the movable parts of the machine. Fig. 5 is an enlarged detail taken through the anvil and slat-delivering cylinder, showing the manner in which the riveting operation is conducted. Fig. 6 is an en- ,States Letters Patent.

larged fragmentary detail showing the mechanism for actuating the riveting and setting punches.

Referring now specifically to the structure which characterizes the machine herein shown, A designates the anvil having the form of a hollow cylinder and is rotative. B designates as a whole the rivetingpunch and slat-delivery cylinder located above the anvil. Said cylinder B is also hollow and is provided on its outer cylindric surface with a plurality of longitudinal parallel pockets 1), adapted to receive the slats which are to be fastened to the web of the conveyer-belt and to deliver said slats to said belt prior to the riveting operation. The cylinder B is arranged over the anvil A, and the web or belt passes between the same to receive the slats, which are delivered thereto by the upper cylinder, and the slats are fastened to the web or belt at a time when the cylindric faces of the cylinder are closest to each other. The stepby-step advancement or rotation of the cylinders feeds the belt between the same and also delivers the slats successively to the belt.

The conveyer-belt shown is of familiar form, it consisting of two or more/flexible belts or bands O, usually made of leather, a continuous web 0, usually made of canvas, and'a plurality of slats G which are arranged transversely of the parallel belts and the web and are attached thereto by rivets and washers c 0, respectively, the latter being herein shown as made in accordance with the invention set forth in my aforesaid prior United The washers are made conical and fit conical sockets in the slats, entering said sockets from the outer faces thereof, and the rivets are designed to be passed outwardly through the belts into the smaller ends of the conical washers and upset therein.

The hollow cylindric anvil A is provided at its ends with thickened parts or rings (1, (shown more clearly in Figs. 1 and 6,) in which are formed a series of annularly-dis posed radial openings a,- Figs. 5 and 6, one series at each end, in which are seated and through which reciprocate a series of radially-disposed setting-punches D. Said setting-punches are provided with square outer ends and are adapted to be normally retracted to their inner positions, with their inner ends a distance inside the cylindric outer surface of the anvil, by means of spiral expansively acting springs d, surrounding the same and interposed between the inner cylindric surface of the anvil and the heads (1 of said setting-punches. The setting-punches D are arrested in their retracted positions, in which they are held by the action of the springs (Z by means of set-screws d having screw-threaded engagement with the thickened or ring end portions of the cylinder and entering keyways d in said punches. There are a number of said sockets a in the rotative cylindric anvilA,equal to the number of the pockets 1) of the cylinder B. The withdrawal of the punches D, with their ends inside the exterior surfaces of the cylindric anvil, constitutes pockets in which are placed the rivets before each set of setting-punches reach the riveting positions. When said settingpunches reach their operative positions, which is at the top of the rotative anvil in the present construction, the punches are advanced to thrust the rivet through the belt and web and into the smaller ends of the washers, and the rivets are held in position by said punches while they are upset. It will be observed that the conical washers of the rivets extend practically through the slats, and the smaller ends thereof are sharp, so that when the rivets are advanced by the setting-punches the forward ends of the rivets and the sharpened ends of thewashers constitute, in effect, dies which serve to facilitate the cutting of cores from the work, and thus form holes to receive the rivets, the cores being forced into the washers.

The riveting-punches E, which upset the ends of said rivets, occupy and reciprocate in radial openings 1), formed in thickened portions or rings at the ends of the upper cylinder, as more clearly indicated in Figs. 5 and 6, the punches of each set being in line with the pockets I). Said riveting-punches extend with their inner or headed ends within the interior of the hollow cylinder B and are adapted to be held in their retracted positions by means of spiral springs e, surrounding the same and interposed between the inner surface of said cylinders and the heads 6 of the riveting-punches Suitable stops are provided for limiting the rearward movement of said riveting-punches under the action of the springs, comprising, as herein shown, set-screws 0 having screw-threaded engagement with the ring portions b of said cylinder and engaging recesses e in said riveting-punches, as more clearly shown in Fig. 6. The advance ends of said rivetingpunches are reduced, as shown at e, and said advance ends of the punches are guided in the reduced inner ends of the openings 1) and are adapted when projected in their outermost positions to extend into the ends of the pockets 1) of the cylinder sufficiently far to properly engage the rivets of the slats then occupying said pockets. The outer ends of said openings 5 within the slat-pockets b are surrounded by conical projections 5 said projections engaging the larger ends of the conical washers in a manner to properly center and hold the slats in the pockets when the slats are delivered thereto in the manner to be hereinafter described. The advance ends of the riveting-punches are preferably roughened or made with cross-cutting edges in order to facilitate the reduction of the cores ITO cut from the work during the setting operation and also to facilitate the upsetting of the rivets.

It will be observed that the thickened ring portions of the cylinder and anvil constitute the effective portions thereof, so that while said thickened end portions are herein shown as being connected by an integral tube portion it is evident that the connection of said rings may be otherwise effected. It is to be furthermore observed that for some kinds of work a cylinder having a single annular series of coacting punches may be employed, thereby shortening the cylinder.

The rotating anvil A and the cylinder B are so mounted and actuated as to be rotated step by step, so as to bring the riveting and setting punchesseverally into line or operative position, and between such steps of rotation the riveting and setting punches are actuated to first thrust a rivet or rivets through the work, and thereafter the riveting-punch is advanced upon the end of said rivet or rivets in a manner to upset the same, said rivets being held in position during their riveting by the setting-punches. Any suitable means may be employed for mounting the two cylinders, whereby they may be thus intermittently rotated and arrested with up per and lower pairs of punches in coactive alinement and for delivering the slats to the upper riveting-punch cylinder. The means herein shown for so mounting and actuating said cylinders are made as follows: The cylinders A and B are fixed to axial shafts A B, which latter have bearings at their ends in end frames F F of any suitable construction. Said end frames are connected together at their lower ends by a connectingbar F. The members may be connected together at their upper ends by a like bar or bars, or the transverse operating-shafts may be relied upon to hold them together. The shafts A B are provided at their adjacent ends at one end of the machine with intermeshing gear-wheels A B and one of the shafts, the shaft B, as herein shown, is associated with means for imparting thereto an intermittent or step-by-step rotary motion, thereby imparting to both the shafts A B and the cylinders A- and B intermittent or step-by-step rotary motion for the purpose stated. Such actuating mechanism is operatively associated with means for locking the cylinders in their arrested positions, whereby the coacting sets of punches are maintained positively in line during their opera tion. The means herein shown for effecting such intermittent or step-by-step rotary motion and for locking the parts stationary consists, essentially, of a mechanical movement known as a Geneva movement. It comprises a disk G, that is fixed to one end of the shaft B of the cylinder B, and is provided on its periphery with a plurality of radial notches g and intervening peripheral depressions g. Cooperatingwith said diskis a continuously rotative disk G,iixed to a shaft G that extends transversely across and has bearing in the frame of the machine. The diskis provided with an eccentric portion carrying a pin g*, which enters one of said radial peripheral notches 9 once during each rotation of the shaft, and thereby acts to turn the said disk G and shaft B through a predetermined angular displacement required for bringing the coacting riveting and setting punches in coactive line with each other. After said pin leaves said slot 9 in the continued rotation of the disk G the disk is locked from further rotation by engagement of the cylindric part of the periphery of the disk G with the peripheral depressions of the disk G. The means herein shown for rotating said disk G and its shaft B are made as follows: H designates a main driving-shaft that extends transversely across the top of the machine and is provided at one end with a belt-wheel H and at its other with a beveled pinion h. Said beveled pinion h meshes with a like beveled pinion '7, that is affixed to one end of an oblique shaft H mounted in suitable brackets f f, extending laterally from the adjacent end member of the machine-frame. Said shaft H is provided at its lower end with a beveled pinion k, that meshes with a beveled pinion g", carried on the shaft G inside the disk G. In this manner the shaft G and disk G are continuously rotated, and the said disks G G operating in the manner described to intermittently rotate the cylinders and lock the same stationary between their periods of intermittent rotation.

As before stated, the belts C of the web C, of which the conveyer is to be made, are fed between the rotating anvil and the slat-de livering and riveting-punch-carrying cylinder, with the belts C in line with the setting and riveting punches at the ends of the cylinders. During the time the cylinders are rotating said riveting and setting punches are held in their retracted positions by their springs e and d, said punches being retracted sufficiently to admit the slats to the pockets 5 of the cylinder B and to admit the rivets tov the outer ends of the openings a of the rotating anvil. After the cylinders have been brought to a state of rest, with the opposed pairs of plungers in line with each other, as stated, and during the time the cylinders are maintained in such state of rest the mechanism is set in motion for setting the rivets and upsetting the same in the manner before stated. The means herein shown for effectin this result are made as follows:

ocated at each end of the machine outside of theirame members F are two generally parallel vertical bars I I Said bars I I carry at their lower ends followers I I, which extend into the hollow ends of the cylinders for operative engagement with the punches. The followers I cooperate with the setting-punches D and the followers I with the rivetingepunches E. Said bars I I are adapted to be reciprocated through the medium of suitably-formed cams and in such manner that the bar I and its follower I are first forced upwardly into their operative positions and the bar I and its follower I thereafter forced downwardly into their operative positions, the lower follower being held for a time in its uppermost position while the riveting-punches are being advanced, so as to constitute the setting-punches at this time stationary abutments, which receive the riveting pressure, and when said followers are retracted the springs d and c restore the punches to their retracted positions. Said bars I I are actuated by cams k h, arranged in opposing pairs on each end of the driving shaft H. The upper ends of the bars I I are provided with suitably-shaped straps t 'L, within which the cams 7L3 h operate. The cams are of course so arranged as to hold separated the followers during the time the cylinders are rotated, so as to move the followers out of the path of the headed ends of the punches at such time. The straps i i, in which said cams operate, are provided on their inner cam-bearing surfaces with notches t t to permit the bars I I to suddenly shift endwise, under the action of the springs d and e, and the followers to suddenly separate when the cams strike said notches, and said notches are so disposed that such sudden separation of the followers takes place at the completion of the upsetting movement of the riveting-punches and just before the cylinders are turned another partial rotation.

Any suitable means may be employed to deliver the slats to the pockets 1) of the upper cylinder B, or the slats may be delivered thereto by hand. As herein shown, said slats are delivered to said pockets at the upper side of the cylinder through a suitable chute J, that is arranged to register with the uppermost pocket of the cylinder B when the latter is brought to a rest. Such delivery takes place by gravity from said chute at a time when the upper cylinder is stationary. Curved guard-bars J, attached at their upper ends to said chutes and extending around the cylinder at the one side thereof to the lower side of the cylinder, hold the slats in said pockets during the time the slats are being carried downwardly in said pockets on the descending side of the cylinder. Two of such guard-bars, one at each end thereof, are preferably provided.

Any suitable means may be employed for positively advancing the conveyer between the cylinders as it is being formed. As herein'shown, the interlocking connection of the slats with the pockets 6 is availed of to effect such positive feeding movement. For this purpose an idle roller K is located in front of the cylinders A and B and adjacent to the rising side of the cylinder B, whereby the formed conveyer is held engaged with the upper cylinder and the slat last fastened in place interlocked with one of the pockets until the slat next in rear is fastened in place.
