RIVETING MACHINE.
Application filed September 24, 1923. Serial No. 664,477.
T 0 all whom t may concern:
Be it known that I, l/VALTnR T. Gonne-N,
through the work, preparatory to heading" the rivet in the work.
The invention is herein illustrated and described as especially directed to the feed mechanism of a riveting machine employed in the manufacture of drapers or conveyors for carrying straw, chafll and grain in binders, separators and other agricultural implements. As customarily used the draper comprises a web of canvas `with leather strips on one side and transverse, wooden strips or cleats on the opposite side of the web. The feed mechanism of the present invention is for `use on machines which are employed to rivet these three elements together, but it will of course be understood that such machine may be utilized in the manufacture of other articles or commodities of similar nature. I
In the utilization of my invention I employ in combination with a power operated riveting machine having a well known type of spinning head for heading the rivet, manually controlled feed mechanism for coaction with the spinning head, whereby the draper or work is brought to operative position and the rivet punched through the draper preparatory to the step of heading the rivet. By thismeans the parts of the draper or work are securely fastened without danger of splitting the wood cleat or injury to other parts of the dra-per, and rapidity and accuracy `in the operation o-f the machine are accomplished. The iiiveiition consists in certain novel combinations and arrangements of parts as illustrated in the accompanying drawings wherein I have illustrated one complete embodiment of my invention, the parts being combined and arranged according to the best mode I have thus far devised for the practical applica-` tion of the principles of my invention.
F igurell is a view in side elevation of an electrically operated riveting machine equipped with my improved feeding mechanism, the parts being shown in inoperative position.
Figure 2 is a top plan view of the machine, showing in dotted lines the position of the draper 0r work to be operated on.
Figure 3 is a vertical sectional view of the machine, with parts shown in elevation.
Figure L1 is a perspective view of the frame, detached, for supporting the operative parts of my feed mechanism.
Figure 5 is an enlarged, front elevation at the head of the machine.
Figure 6 is an enlarged detail view of the cam. and .lever mechanism for elevating the anvil and operating the punch which feeds the rivet to the work.
Figure 7 is a detail sectional view of a p art of the. draper showing a completed rivet joint.
Figure 8 is an enlarged, vertical sectional view of the anvil and punch, or driver.
In order that the relation of parts may readily be understood I have shown in the assembly views Figs. 1 and 3 so much of the riveting machine as is necessary for this purpose.
The machine is supported from the bed plate 1 and main frame 2, and is operated by the electric motor 3 through the driving belt et, pulley 5 and spindle 6. The spindle is rotated and reciprocable and is supported in bearings 7 at the head of theV machine. The rivet-heading tool 8 at the lower end of the spindle rotates with the spindle to spin and form the head of the rivet and co-operates with the angular plate 9 attached to the frame-head through the guide plate l0 which is provided with an opening or hole 11. By depressing the pedal 12 the spinning tool 8 is forced down to operative position within the opening 11 for co-action with an anvil as will be described. Suitable means are employed for transmitting the motion of the pedal to the spinning tool, as for instance spring 13 which normally lio-lds the pedal in uplifted position, the connecting rod 14E, link mechanism 15, a lever 16 which is pivoted at 17 in the frame of the machine, and the head 18I on the lever which operatively engages the spindle to permit its rotation and to impart a reciprocatory niotioii thereto. Thus it will be apparent that the spinning tool as it is rotated I nayl be depressed by action of the pedal: 12 and. is. returned or retracted to uplifted positionby action ofthe spring 13.
While the machine is adapted for other work I have specifically illustrated herein the construction of ax draper as seen inFigs, 2 and 7 in the manufacture of which the machine is particularly applicable. I ihe draper comprises a canvas web 19 to one side of. which are secured longitudinal leather strips or belting 20, andatthe oppositeside of the canvas web are secured transversely disposed woodgcleats ordraper sticks 2 2.
The cleats as seen in Fig. 7 are provided with counter-.boredI recesses 22L andV vthe rivets 22 are punched through the leather', canvas and strip or cleat with thi,` head 23 of the, rivet forced into the leather beltjing or strip. f-r washer 24, which is placed in the recessfor cO-.action with the head=2 5. of the rivet which is Spun from the upper end of the rivet shank by the operation of the spinningy tool 8 in well knownma-nner.
The feed mechanism for presenting the work to the spinningtool is supported in a hollow frame 26 securedto the main frame of the machine as by bolts 27, and the angular portion 28 of this supporting frame is fashioned with a circular. opening 29l in,v its top plate 30, located directly below theA spinning tool as indicated in the drawings.
Manually controlled-means are employed for actuating the feed mechanism, which mechanism includes a vertically disposed shaft 31, axially alined with the spindle 6 and below the saine. This shaft or bar 31 is de.- signed to be reciprocated vertically and guided in the alined openings 29 and 32, of:
the frame 30, and held against rotation by means of the guide key 33m-acting with the wall of the opening 32..
At the head .ofthe ba: is seated an anv-.il
34 having a socket 34 to fit ver the head of the bar, and the anvil is adapted to sup-gI port the draper or work while being riveted` by the spinning tool 3. ln its upper end .thev
anvil carries a bushing 35 which is resiliently supported in its recess y3b on the. spring 3T, and suitable means are utilized tov preventl the spring, which is under tension, from forcing the bushing entirely from `its pocket or recess.
The resiliently supported guide bushing` 35 surrounds the upper end of a, punching tool 38 which is rigidly fixed in t'he anvil centrally thereof, and as seen inr Fig. Sthe.
order that .when the anvil is` elevated as will` are loose on the rock shaft 44;
tactl witlrthe lower face of. thedraper or of theleather beltingon thecanvas web, and as tllebar 3l is elevated the resiliently supported bushing is pushed into its pocket. As the bushing is retracted the rivet is punched or forced into the draper and as the draper is held against upward movement by thel plate v10, the rivet shank is passed through the draper andits washer 24. Then the spinning tool by its act-ion on the upper end of the shank ofthe rivet, spins a headon the rivet. as indicated at 25in Eig. 7. The feed bar 31 is thenlowered and the draper is moved to, position -for a repetition of this riveting action. If necessary the .top
preventrotation of thelatter. while the spinsY ning toolzis operating.
The non-rotatable reciprocable bar 31 is fashionedfwith an upper cross head just below the anvil 34 and this cross head which is iixedto the bar is fashioned with horizontally projecting trunnions .40. A pair ol links 411having slots 42 at their upper ends are connected with the trunnions, and at their loi-Wer ends these links are pivotally connected with a pair of crank arms 43, one at each side of the bar 31and liked on the crank shaft 44..v The horizontally disposed crank shaft 44 is journaledin bearings in the frame 30v and is provided with a hand lever 45 for actuating the bar 31- through this described connection, to elevate the anvil and the punching tool carried thereby. By turning the lever to the right in Figs. 3 and 6 it will be apparent that the shaft 44 is rocked, the arms 43 swing with the shaft, and the links 41 connected with trunnions 40 of the cross head 39 force upwardly the bar 31 and its anvil, Byzthe utilization of thc slots 42 in the links 41 a further, but slight elevation may be iin-parted to the bar 31 and the anvil, in order that the weight or .load on thelanvil, as thespinning tool operates, may be shifted from the links to a more stable support.
For this purpose I utilize a fixed collar 46 havinga second cross head 47 located below the cross head 39 and rigid with the bar 31. A pair of anti-friction rollers 48 are journaled on the cross headV 39r for co-action with lthe pair of arcuate cam plates49 that 45 which is rigid withl the rock shaft is adapted to` be rigidly connected with the cams or camv plates, which are slotted 4at 50,l byf means of a. pin 51v carried by the lever and projected into these slots 50. The slots 42 vin thelinks 41 and the slots 50 in the ciam plates 49-are, positioned .and arranged with relation to the trunnions 40 and pin 51 in such manner that the first or initialV movement of the lever willhelevate the anvil The lever A CII through vthe connection with the uppei` cross head 39. Then by a continued movement of the lever the cam plates through the pin connection and rollers 48 relieve the load from the links, whose slots 42 permit this additional movement, and the load is directly supported on the cams through the rollers on the lower cross head. Thus, after the anvil has been elevated to position for co-action with the spinning tool, the weight of the load to be imposed on the anvil is shifted from the links to the cam connection and support. When the spinning tool is lowered to operative position and is spinning the 4head on the rivet the pressure on the lever 45 is relieved and the operator who has control of the lever will not be required to resist las great a strain as would be the case were the load on the links 41.
Vertically adjustable bearing blocks 52 may be provided for the rock shaft and these bearing blocks may be elevated or' lowered in connection with the slots 53 in the frame 30, in order that the feed mechanism may be adjusted with precision for the performance of its functions.
From the above description taken in connection with my drawings it will be apparent that I have pro-vided in combination with the riveting machine a simple but effective feeding device which may be manipulated with facility by the operator for reliable, rapid, and accurate performance of its required functions. The electrically operated machine may be controlled through the pedal mechanism and the feeding mechanism by manually operated means under the attention of a single operator who thus has the entire machinery under his direction.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. The combination in a. riveting machine with a supporting frame of a reciprocable bar and an anvil thereon, a guide bushing having a resilient support in said anvil, and a punching tool in said anvil and bushing adapted to support a rivet.
2. The combination with a reciprocable bar and a work retaining plate, of an anvil secured at the upper end of the bar, said anvil having ta recess and a resiliently supported depressible bushing carried by said anvil in said recess, and ai punching tool fixed in the anvil and disposed within said bushing to support a` rivet therein.
3. The combination with a work retaining plate of a. reciprocable bar having a. resiliently supported depressible member and a relatively fixed punching member adapted to support a rivet, means for elevating said bar, and co-acting means for imparting an additional movement to said bar whereby said bar is stabilized in its elevated position.
4. The combination with a work-abutment, of a reciproca-ble anchor-bar having a resiliently supported abutment member, a rock shaft and means for operating it, means actuated from said shaft for elevating said bar, and coi-acting means actuated from shaft for imparting an added movement to said bar whereby the latter is stabilized in its elevated position.
5. The combination with an abutment member, of a reciprocable anvil bar having a cross head and trunnions thereon, a rock shaft and lever therefor, crank arms on said shaft and slotted links connecting said arms and trunnions, and means co-acting with said lever and bar for imparting an added movement to said bar whereby the latter is stabilized in its elevated position.
6. The combination in a riveting machine with an abutment member, of a reciprocable anvil bar having a pair of fixed spaced cross heads, trunnions on one cross head and antifriction rollers journaled on the other cross head, a rock shaft having a pair of rock arms, slotted links connecting said -arms and trunn'ions, a pair of cam members on said shaft for co-action with said rollers, a lever for operating the shaft, and a pin on said lever having a slotted connection with said cam members.
7 The combination with a. work retaining plate, of a reciprocable `anvil supporting bar having a resiliently supported depressible member and a relatively fixed anvil member adapted to support a rivet, means for elevating said anvil bar and co-acting means for imparting an additional movement to said bar whereby said bar is stabilized in its elevated position.
In testimony whereof I afiix my signature.
