1,0313260. Specification of Application filed Kay 15, 1911.

,To all whom it may concern:

Be it known that I, An'riwn R. HAvENnii,"'

a citizen of the United States, residing at Walt-ham, in the county of Middlesex and State of Massachusetts, have invented new and the like.

The object of the invention is to provide a cheap, simple and easily operated machine for fastening strips of sheet material to the corners of trunks or for fastening such strips to the sides of trunks intermediate the corners.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings: Figure 1 is a side elevation of my improved riveting machine, the same being partly broken away and shown in section. Fig. 2 is a front clevation of the same. Fig. 3 is a sectional elevation enlarged taken on line 3-3 of Fig. 1. Fig. l is a sectional plan taken on line 41- 1 of'Fig. 2. Fig. 5 is a sectional elevation taken on line 55 of Fig. 2, looking toward the left in said figure and a portion of a-trunk being illustrated together with the strip riveted thereto. Fig. (3 is a sectional elevation taken on line 6'G of Fig. 5 looking toward the left in said ,figure. Fig. 7 is a sectional plan taken on line 7-7,

tions. Fig. 11 is a vertical sectional eleva- ,tion of a modified form of work-support and trunk feeding mechanism. Fig. 12 is a plan, partly in section, of the horizontal lever and actuating mechanism which are illustrated in Fig. '11, the lever being broken away to save space in the drawings.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, referring to Figs. 1 to 10, inclusive, 15 is the frame of the machine consisting of a head 16 and a base 17. The

trunk or other work to be operated upon is supported upon a work-support 18 which consists of a bracket having a horizontal arm 19 and a X'CItlCtll arm 20. The arms 19 and 20 are hollow and are each closed at one terminates at its upper end in a feed finger 26 fast to said feed lever and foaming, in effect, a portion thereof. The feed finger 26 is slotted at 27 to receive the cross-bar 28 of the upper end of the work-support and the arms 29, 29 of the bifurcated portion of said feed finger are provided with corrugations or teeth 30 upon their upper edges which bear against the under surface of the trunk 24 during the feeding operation. The feed lever 25 (Fig. 4) is slidably mounted upon a block 31 which, in turn, is pivoted on a stud 32 which adjustable longitudinally of the vertical arm 20 and is clamped there- ,to by means of a nut 33 which has screwthreaded engagement with the stud 32. The stud 32 terminates at one end thereof in a projection 34 which projects into a slot 35 in the plate 22, and adjacent to the slot 35 is a series of lines forming a scale numbered from 0 to 60 which indicates the length of .feed imparted-to the feed finger 26 when vthe projection 34 is in line with these different lines of the scale, (Fig.1).

A combined rocking and longitudinal motion is imparted to the -lever 25 by a lever 36' which is connected thereto by a pin 36' and said lever 36 is slidable longitudinally thereof'upon a block 37, said block bein pivoted driving shaft 49. The main driving shaft 'meshing into a bevel gear 43 fast to a vertical shaft 44 which is journaled in bearings 45', 46 in the base and head 17 and 16, respectively. A bevel gear 47 is fast to the upper end of the shaft 44 and meshes into a bevel gear 48 which is fast to the main 49 is journal'ed in bearings 50, 50 in the head of the machine and is rotated by a clutch pulley 51 (Fig. 2).

The rivets which are to be driven into the ftrunk are placed in mass in a hopper 52, the rotary member 01 which is driven by a belt 53 and pulley 54, said pulley 54 being fast to the shaft'49. The rivets pass from the hopper 52 down a raceway 55 to a separator slide 56, which separator slide isoperated to feedthe rivets one by one to the lower portion 57 of the raceway 55 by a lever 58 pivoted at-59 to the head 16 and rocked in one direction by a spring 60 and in the other direction by a projection 61 upon a-link 62 to which a reciprocatory motion is imparted as hereinafter described. The rivets pass one by one in a manner well known to'those skilled in the art from the lower portion 57 is. fastened to a slide 66. The slide- 66 is of the raceway into a rivet holder 63. This rivet holder is made in two parts 64, .64, each supported upon aspring arm which guided in ways 67 in the head of the machine.

The driver .68 is fast to a driver bar 69 which is guided. in ways 7 0 in the head of the machine and has a reciprocatory motion impartedthereto by a pairof toggle links 71 and 72. The link 71 is pivoted at 73 to the upper end of the driver bar 69. The link 72 is pivoted at one end thereof upon an eccentric 74 formed upon a stud 75 which is journaled to rotate in the head 16. .(see Figs. 2 and 3). The stud 75 can be rotated and locked in different positions by a'handle 7 6 which carries a spring-actuated 1 locking pin 77 adapted to be forced by the spring 78 into any one of the holes 79, 79 in the locking plate 80 which is fastened to the head 16. The links 71 and 72 are con nected by a pin 81 to the link 62, the other end of said link 62 being pivoted to a crankpin 82' fast to a disk 83 which, in turn, is fastened to the shaft 49. Thus, by the r0 .tation ofthe crank-disk 83and its crank-pin 82 a reciprqcatorymotion is imparted to the link 62 which, in turn, 72 andflli pon their pivots 74 and 78, re.- spectiveiy,thus imparting a reciprocatery motion to the driver bar 69 and to the driver 68.

rocks the links- The rivet holder slide 66 is moved upwardly in its ways 67 by a spring 84 (see Fig. 1). It. is moved downwardly by the driver bar 69 which is adapted to engage a pin 85 as said driver bar descends (see Figs. 9 and 10). The pin 85 is mounted to slide transversely of the rivet holder slide 66 and has a reciprocatory motion imparted thereto transversely of said slide by a lever 86 pivoted at 87 to said slide. The lever 86 has an arm 88 thereon which projects downwardly'into a slot 89 in the pin 85.

When the parts are in the position illustrated in Fig. 9, it will be seen that the pin 85' is held in such position that it will be engaged ty the driver bar 69 as said driver bar descends. This will carry the rivet holder downwardly, together with the rivet holder slide 66, until the portion 90 of the lever 86 engages the top of a stationary stop 91, when said lever 86 will be tipped, by its engagement with-the stop, from the position illustrated in Fig. 9 relatively to the slide 66 to that illustrated in Fig. 10, the head or flange 92 upon the stop 91 entering at this time a notch 93 in the lever 86, and the lever being tipped upon its pivot will move the locking pin- 85 out of engagement with the driver bar 69, which'will then continue its downward movement until it has driven the rivet out-from between the two spring supported sides of the holder 63 and through the strip 94 and the side of the trunk 24, and has clenched the rivet 95 against.- the anvil 23. Upon the reverse I110- tion, when the driver bar 69 is moved upwardly sufiiciently to clear the right hand end of the pin 85 (Fig. 10) a flat spring 96, which bears against the outer end of the pin 85, will drive said pin forward or to the right (Fig. 10)., to the position illustrated in Fig. 9, thus disengaging the lever 86 from the head 92 of the stop 91 and allowing the rivet holder slide 66 to be moved upwardly by its spring 84.

When a corner piece 94 is being fastened to the trunk 24, as illustrated in Fig. 10, it is held firmly in position against the outer surface of the trunk by a presser foot of the style illustrated in Figs. 7 and 10, in which the presser foot 97 has an angle plate 98 at the bottom thereof which bears against the top and side of the corner piece 94, as clearly seen in Fig. 10. This angle plate "98 is clamped to the lower end of asleeve 199 by a nut 100 which has screw threaded engage ment with a projection 101 at the lower end of the sleeve 99. -The sleeve 99 is mounted to slide vertically upon a stud 102 which, in

turn, is adapted to slide within a vertical rea cess 103 in the head 16. of the machine (see Fig. 5). A spring 104 encircles the sleeve 99 and bears at its lower end again 105 upon said sleeve, while at it p itbears against a cross-pin 166 which is of-the machine. A s prin to the sliding stud 102 and projects through slots 107 in diametrically op osite sides of the sleeve 99. The sliding stud 102 may be moved 'upwardly or downwardly by means.

of a lever 108 which is connected to said slide by a pin 109 and is pivoted at 110 to the head of the machine. Upon the lever 108 is mounted a locking latch 111 whichis pivoted at 112 to the lever 108, one end of said latch 111 being provided with a notch 112' adapted to engage a rib 113 upon the head 111 holds the free notched end of theloc ring latch 111 in engagement with the rib 113 when the parts are in the position illustrated in Fig. 9, thus locking the'presser foot downwardly and clamping the corner piece 94 to the trunk 24 itbeing understood that while in this position the spring 104 will yield slightly during the feedin of the trunk along he'- n'eatluthe presser oot plate 98.

The PIGSSGI' fOOt late illustrated in Fig.

8 is substantially t e same as that illusriveted to' a portion trated in Fig. i as to the manner in which it is supported and actuated, but differs therefrom in that it is slotted upon its under side to straddle a flat strip 114, as seen 'in Fig. 8, the portions 115, 115 of said presser foot extending down and along the opposite edges of the strip, 114 and thus forming a guide'for said strip as itais being I of the. trunk intermedi- -ate the corners' I i The general operation of the mechanism hereinbefore specifically described is as follows: The trunk 24 is placed with one cor- 1 ner thereof esting upon the vertical arm 20 of the wor support 18 as illustrated in Figs. 5and 10. The operator places the corner strip 94 on the corner of the trunk and lowers the presser foot to the position illustrated in Figs. 9 and 10 and-clamps the same in that position by forcing the lever 108 downwardly until the notched portion 112',of the locking latch 1.11 drops in beneath the rib 113 onQthe head of the machine, as illustrated in Fig. ,9. He then throw: the elutolrinto pperation by means of "a ti eadle" (not shown in the drawings) which op tes a rod 116 (Fig. 1), this rod, in turn, opcratinga clutch lever 117. The clutch pulley, 51 is thus locked to the shaft 49 ,and rotates the saipla, causing the driver bar'69 tojbe mgved 'qlo wm ardly by the links 62,7 1,- and "72, and as said driver bar moves downwardly with its drider, it carries with it the rivet holder 63, with one of the rivets 95 therein, until the under side of the rivet holde r n'early touches the upper surface 5f thefstrip 94.." At this time the portion '90 uponth'e" lever 861will engage the flange 92 upon the'S'tOP 91 and throw the locking pin 85 out of engagement with the driver ,bar 59 and the'flange 92 will project into the notch-93 upon sa d lever 86 and thedownward motion of the rivet holder and the slide 66 will be stopped. The downward movement if the driver bar 69 and the driver 68 will, however, continue and the rivet will be driven out from between the two sides of the rivet holder, down through the angle piece 94.- and through the side of the trunk until the ends of the bifurcated rivet are turned by the anvil andblehched upon the inner surface of the trunk 24. As the driver bar moves up from the position illustrated in Fig. 10 toward that illustrated in Fig.

'9, the lower end of the driver'bar will pass upwardly above the in 85 and said pin then being released Wlll be moved forward or toward the right (Fig. 19) by the flat springADG and will tnus free the lever 86 from the stop 91. After this has been accomplishedthe spring84= will act to carry. the rivet holder slide 66 and the rivet holder thereon upwardly to its uppermost position as illustrated in Fig. '9. As. soon as the driver bar starts up the trunk is fed for; ward bythe lever 25 which is so timed as to be move upwardly into engagement with be moved toward the left (Fig 1) to feed the trunk and strip forward in order to receive another rivet. The combined reciprocatory and rocking movement is imparted to the lever 25 by the lever 36, eccentric 39 and shaft 40. The operation of alternately driving the rivet and feeding the trunk is repeated until the entire strip has been attached to. the corner of thetrunk, whereupon the operator stops the machine by releasing the treadle and throwing out the clutch.

It, will be seen in the form of my invention illustrated in Fig. 1 that the trunk can be fed along the work-support toward the head 16 and base 17 only so far as the length of the :horizontal arm 19 will allow and, therefore, for longer corners of the trunk another style of arm and mechanism for feeding said .trunk is used, whereby said trunk, instead of being fed toward the head 16 and base 17, will be fed transversely thereof, the rest of the mechanism of the machine remaining the same and performing the same functions as hereinbefore described, and in Figs. '11 and 12 I have illustrated the modified form whereby it is possible to feed the trunk transversely .of the head and base and trans: versely of the horizontal arm of the worksupport. Referring then to Figs. 11 and 12 it will be seen that 18 is the work-support having a horizontal arm 19 and a' vertical arm 20', the work-support being fastened to the base 1.7. The shaft 40 has a cam 11S fast thereto and working between the jaws. 119, 119 on one end of a lever 120 which is pivoted upon a pin 121 fast to a block 122, the block 122 being, ,Lturn pivotally mounted upon a stud fast to the 5119 the inner surface of thetrunk and then to The cam 118 thus imparts a rocking motion to the lever 120 in a vertical plane and about the pivot 121.. A rocking motion in a horizontal plane about the pivotal stud 123 is also imparted to the lever 120 by a cam 124: which engages a cam roll 125 journaled upon the lever 120. The lever 120 is connected by a universal joint 126 to the lower end of a lever 127 which lever is slidable longitudinally thereof upon a block 129 which,in turn, is pivoted upon a stud 128. The stud 128 is adjustably fastened to the vertical arm by a nut 130, so that the lever 127 can slide longitudinally thereof upon the 1;; block 129 and can rock about the stud 128 as a pivot, thus imparting a compound. four motion feed to the upper end of'the lever 127 similar to that hereinbefore described with relation to the lever 25, except that in this 20 case the lever rocks in a plane extending transversely of the horizontal arm .19,

whereas in the former case said lever rocked in a plane extending longitudinally of the arm 19'. The operation of the machine otherwise is the same, as tothe driving and feeding of the rivets, in the form of my invention illustrated in Figs. 11 and 12 as in the form of my invention illustrated in Fi 's. 1. to 10, inclusive.

,30 ft will be understood that the thickness of the sides of the trunk 24 or of the corner strips 9 1 may vary, but that the inner face of the trunk willalwa'ys occu' y the same position relatively to the anvi and to the feed finger; Therefore, it follows that for different thicknesses of trunk and strip, where different lengths of rivetare employed, in order to obtain. the same clench of the rivet on the inner face o'f-the trunk,

40 the point at which the lowermost end of the driver'must stop and the, point at which the lowermost end of the rivet holder must stop will vary. To compensate for this variation, the eccentricstud 74 is utilized to determine the lowermost point at which the lowermost end of the driver will stop, said eccentric stud 74 beingset and locked in different positionsby means of the' handle 76 and its" locking pin 7,7, and the-lowermost position .50 of the rivetholder is regulated by means of the stop 91 which has screw-threaded adjustment with a bracket 91 and is locked thereto by a set-nut 91 If the thickness of the trunk is greater in one case than another, then the stgp 91 is screwed upwardly so that the pin-"$5k may be. thrown out sooner and thus stop therivet holder slide 66 and rivet f holder 63 at a greater distance from the anvil or at a greater distance from the inner hoo fapeof the whichgbea'rs against the wonlr-snpport. In thecase of the'driver-bar and driver, itthe thickness of the trunk is increased, then the handle 76 is moved up WardlyQIfifiWflIfd the right (Fig. 5), thus no raising the eccentric portion of thestud 74f 5. A machine for riveting stripsi j ustably fastened-to said work-sup-portupon and hence raising the lowermost end of the driver to correspond to the increased thicl ness of the trunk which is being riveted.
