SAMUEL G. LAY, OF RIDGEVILLE, INDIANA.

BROOM-NAILING IVLAGHINE.

To all whom it may concern:

Be it known that I, SAMUEL O. LAY, of Ridgeville, county of Randolph, and State of Indiana, have invented a certain new and useful Broom-Nailing Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts.

The object of this invention is to provide a practical machine for stapling brooms and the like and in that connection to sever the staples successively from the coil of wire and form them as they are driven. Also the severing means is so arranged as to form oppositely beveled ends or points on the staple whereby as the same is driven said ends or points will be bent to clench the broom material.

Heretofore, so far as I am aware, brooms have been nailed or stapled by hand. This machine has been invented to accomplish that object mechanically so that the broom may be more accurately and satisfactorily stapled and it be more rapidly and cheaply done.

The full nature of this invention will be understood from the accompanying drawings and the following description and claims.

In the drawings Figure 1 is a front elevation of the machine with a broom in position to be nailed. Fig. 2 is a front elevation of the wire feeding mechanism showing the same in a different position of operation as compared with Fig. 1, parts being broken. away. Fig. 3 is a vertical section through a portion of the machine, substantially on the line 3-3 of Fig. 7, showing the stapleforming mechanism, parts being broken away. Fig. 1 is an elevation of the right hand side of the machine, the machine being in operation and the broom being nailed and being shown in vertical transverse section. Fig. 5 is an elevation of the left hand side of the machine, the machine not being in operation. Fig. 6 is a horizontal section of a portion of the machine on the line of Fig. 1. Fig. 7 is a similar sect-ion on the line 7- of Fig. 1. Fig. 8 is the same as Fig. 7 with the staple driving means in its lower position and in horizontal section. Fig. 9 is a vertical section on the line 9--9 of Fig. 7. Fig. 10 is a similar section on the line 1010 of Fig. 8. Fig. 11 is a horizontal.

section on the line 11-11 of Fig. 1. Fig. 12 is a vertical section on the line 1212 of Fig. 1. Fig. 13 is a horizontal section 011 the line 13-13 of Fig. 1. Fig. 14: is a vertical section on the line 14.14L of Fig. 11, parts being shown partially broken away. Fig. 15 is a plan view, parts being centrally broken away. Fig. 16 is a vertical section transversely of the machine and through the wire guiding means. Fig. 17 is a central vertical section through the guide-frame and staple driver therein and associated parts, and of the broom and broom support, the staple driver being in its elevated position and the broom in its lowered position. Fig. 18 is the same with the broom elevated and the staple driver moved down to its lowered position. Fig. 19 is a perspective view of the stationary cutter plates for severing the wire into staple sections. Fig. 20 is a perspective view of the same plate at a slightly difierent angle of the wire and wire former just before the wire is severed. Fig. 21 is a perspective view of the movable cutter plate and a portion of the stationary cutter plate, the latter being partly broken away to show the parts as they are ready to cut the wire.

Referring now to the details of the construction of the machine shown herein for the purpose of illustrating the nature of this invention, there is a main frame formed of inclined uprights 20 with a table 21 at the top and cross bars 23 and 2 1, rods 25, a vertical bar 26 on each side, see Figs. 4c and 5, and a. short cross bar 27 between the bar 26 and upright 20. The table 21 projects to the right beyond the frame 20 and under said table two triangular brackets 28 and 29 are mounted, the bracket 28 to one upright 20, see Fig. 4., and the bracket 29 to the vertical bar 26, the outward ends of said brackets being brought together, as shown in Fig. 4, and made integral with the vertical bearing 30 for the downwardly extending spindle 81 of the reel 32. Fingers 33 are provided in the reel about which the coil of wire 34. is placed. A strand of the wire 34 is drawn from the coil, as shown in Fig. 1, into the main part of the machine for the purpose of providing staples.

The broom 35, which is to be nailed is formed of broom-corn surrounding one end of the handle and a pair of metal bands 36 and 37 surround the broom-corn and the in ner end of the handle; and the object of the machine is to drive staples through the bands and broom, as appears in Fig. 4. The broom support consists of a small plate or table 88 that has a downwardly extending ear 39 pivoted by the pin 40 to the upwardly extending car 41 from the screw 42. The table is leveled and maintained in its desired position by the segmental bar 43 secured to the under side of the table and provided with a curved slot 44 through which a set screw 46 passes that enters the head of the screw 42. The table, therefore, is adjusted by loosening the set screw 45 and leveling the table by hand to the proper position and then tightening the set screw 45. The large screw 42 extends downwardly through the opening 46 in the cross bar 23 at the front of the machine, see Figs. 1 and 12. The screw passes loosely through the hole 46. The bar 23, therefore, is merely a guide for the movement of the screw 42. Upon said bar 23, see Fig. 1, there is a bearing plate 47, which carries two rollers 48, one at each side of the screw 42. Upon said rollers the plates 49 rest, said plates being the forward ends or extensions of a bar 50, see Fig. 4.

The upper surface of each plate 49 varies in elevation as shown in Fig. 12, the forward portion thereof being vertically wider than the rear portion so as to form an inclined surface 51. The two plates 49 are held together by a cross rod 52. Upon the plates 49 a pair of rollers 58 ride and carry a bearing frame 54 that abuts against or engages the under side of the lower part of the adjusting wheel or disk 55 that screws upon the screw 42. By turning the wheel or disk 55 in one direction, the screw 42 will be elevated, and the reversal of the wheel or disk 55 will lower the screw 42 and therefore, the broom support so as to bring the latter to the proper elevation. When the bar 50 is moved rearwardly on the machine to the position shown in Figs. 4 and 12, the means for supporting the screw 42 rides on the widened portion of the plates 49 and therefore, elevates the broom table 38 and holds the broom up in position to have the staples driven into the same, and when the bar 50 is moved forwardly, as shown in Fig. 5, the means for supporting the screw 42 rides on the lower or narrowed portion of the plates 49 so as to lower the broom support and put it in what may be termed the unoperated position. In other words, the broom support is in the position shown in Fig. 5 when the broom is first placed in the machine to be treated. Then the broom support is elevated to move the broom up to its position to be treated, as shown in Figs. 4 and 12. After the staples have been driven the broom is again lowered to the position shown in Fig. 5 for the removal of the broom.

The broom supporting mechanism, especially the bar 50, is operated by the following means. At its inner end, see Figs. 4 and 5, it is fulcrumed by a pin 56 to the lower end of a vertically disposed lever 57 that is fulcrumed between its ends to the fulcrum 58 on the horizontal cross-bar 22, see Fig. 1, that extends between the vertical bars 26, see Figs. 4 and 5. A spring 59 extends from the rear end of the bar 50 forwardly and at its forward end is connected with the cross-bar 23 of the frame, so that said spring tends to draw said bar 50 forwardly and, therefore, throw the upper end of the lever 57 rearwardly. Said lever 57 is actuated or moved by the roller 63 secured to the outer end of the plate 60 that is riveted by the rivets 62 to the gear wheel 61, as shown in Fig. 5. Therefore, at every revolution of the gear wheel 61, the lever 57 is actuated. The upper end of the lever 57 carries a small roller 64 that normally rides against the hub 65 of the gear wheel 61.

The gear wheel 61 is secured on a shaft 66 which is mounted in bearings 67 on each side thereof that are secured upon the table 21. The gear wheel 61 is driven by a pinion 68 on the shaft 69 mounted in the bearing 70 that extends down from the table 21 and the bearing 71 that is mounted upon the table 21. As shown in Fig. 4, the lower part of said bearing extends down below the level of the table. The shaft 69 carries a pulley 72 over which a belt 73 runs for driving the machine. The pulley 72 is mounted loosely on the shaft 69 and is clutched therewith by a sliding clutch mounted on the shaft 69 and operated by a lever 74 fulcrumed in the bracket 75 fastened to the frame of the machine. The lever 74 has a horizontal portion at the lower end thereof from which a connecting rod 76 extends down and is pivoted to a pedal lever 77 that is fulcrumed to the frame at 78. The spring 79 that extends from the lower end of the lever 74 to the bottom of the table 21 tends normally to hold the pedal in an elevated position and also to hold the clutch in the disengaging position. Consequently, the machine will normally be out of gear or operation and will be in operation only when the pedal is depressed. The shaft 69 has a hand wheel 80, whereby it can be turned slightly by hand for any desired purpose.

Upon the table 21 in vertical alinement with the broom support there is a vertical guide frame 85. As here shown this guide frame is integral with plate 21 and as seen in Figs. 5 and 6, has a rear wall that is pro vided with a vertical slot 86, see Fig. 11, and two lateral walls that project forwardly, and a rearwardly extending brace flange 87. Two plates 88 are secured within said guide frame, by bolts 89, as seen in Figs. 1 and 11. These plates extend from the top of the frame down about fourfifths of the length of said frame to furnish a guide-way for the block or head that carries a staple driver 91. The staple driver is secured to the block or head 90 by a plate 92 and screws 93, as seen in Fig. 11. The head 90 and staple driver 91 are vertically reciprocated in said guide by the lever 94 which is fulcrumed at 95 to a stand 96 extending up from the table, see Fig. 5. The forward end of said lever 94 projects through the slot 86 in the rear wall of the guide frame 85, see Fig. 14, and through a slot 97 in the head 90 between a cross pin 98 below and the curved surface 99 above. A pair of rollers 100 are mounted opposite the lever 94 on the rod or pin 98. A set screw 101 projects through the arm 102 on the guide frame 85 and adjustably limits the upward movement of the lever 94.

The lever 94 is actuated by the gear wheel 61, see Figs. 4 and 5. On the right hand side of said gear wheel 61 an annular cam-shaped rib or projection 104 is secured on which a roller 105 rides, which roller is mounted in the rear and lower end of the lever 94. The cam, as is obvious by reference to Fig. 4, would depress the forward end of the lever 94, and such movement of the lever 94 is the positive movement thereof. The lever is returned to its elevated position by the pin 106 on the cam 104 engaging the hook 107 that is pivoted at 108 to the rear end of the lever 94 and forces said hook downwardly as the wheel 61 revolves. The lower end of the hook 107 is held from escape by a rod 109 extending from the lower end of the hook to the ear 110 on the table. The downward position of the hook 107 is shown by dotted lines in Fig, 5, the corner of the table 21 being cut away to permit the downward movement of said hook. When the hook is in its down ward position the cam 104 is in the right hand position shown in Fig. 5. As soon as the pin 106 ceases to depress the hook 107, roller 105 on the lever 94 begins to be forced upwardly by the cam.

The means for cutting and forming the staples will now be described. The wire 34 passes through the tension device 111 that is controlled by the spring 112. Thence the wire passes through the tube 113 that is carried on the arm 114 which is fastened to the tension device, see Figs. 1 and 16. From the tube 113 the wire passes through the feeders 115. These feeders are sharp metal plates adapted to grip or frictionally engage the wire 34 and as the feeders are reciprocated and pushed in one direction, they will draw the wire from the reel and force it into position and as they are withdrawn they will cease to grip the wire, but slide over it, For that reason the plates 115 are beveled on their rearward sides.

The

lower feeder 115 is fixedly mounted on the feeding plate 116, while the upper feeder 115 is mounted on an arm 117 that is pivoted at 118 to the feeding plate 116. The spring 119 fastened to the feeders 115 tends to force the two feeders 115 toward each other and cause them to grip the wire. The feeding plate 116 is suspended from the bar 120 adjustably, said bar having slots 121 through which set screws 122 from the plate 116 extend. The bar 120 is fulcrumed to the pin 123 in the flange 124 that extends sidewise from the flange 87 of the guide frame 85. The plate 116 at its rear end carries a roller 124, which is engaged by a cam shaped plate 125 on a shaft 126 as said plate 125 is revolved and thereby the plate 116 is pushed toward the guide-frame 85 for feeding the wire into the guide-way. The shaft 126 is mounted at one end in a stand 127 on the table 21, see Figs. 1 and 2, and at the other end in the stand 128' on the bearing 71, see Fig. 4. The shaft 126 is driven by a worm gear 129 that meshes with the worm gear 130 on the shaft 66, see Figs. 1 and 4, The plate 116 is withdrawn after its feeding movement by the spring 131 that is fastened to the lower part of the arm 120 and the end of the rod 132 that extends from the flange 133 which projects forwardly from the lateral flange 124, see Figs. 1 and 4. The rearward movement of the arm 120 is limited by the set screw 134 that screws through the plate or flange 133, see Fig. 2.

As seen in Fig. 6, the wire 34 passes through an opening in the right hand side wall of the guide frame 85 and is guided by said opening. The parts are so arranged that at each operation of the wire feeding means the wire will be fed so that its inner end will abut against the left-hand lateral wall of the guide frame 85. ithin said frame as shown in Figs. 6 and 7, there is a stationary cutter plate 135 which is secured to the rear wall of the guide frame 85 by screws 236, shown by dotted lines in Fig. 6. The wire 34, as it enters said guide-frame lies against the face of said plate 135 and upon the knife 136, see Figs. 6 and 9. This knife 136 is a shoulder-like projection on the lower front face of the plate 135 and the front face of the knife projection 136 is beveled or inclined, as shown in Fig. 6. There is a vertically reciprocatory staplecutter plate 137 that moves downwardly along the front face of the plate 135 and upon the wire 34 that projects into the guideway 85. It is beveled at 138 vertically along the inner surface at its right-hand inner corner so that the lower edge of said beveled surface will form a knife that will coiiperate with the knife 136 to sever the wire obliquely, as seen in Fig. 7. As the plate 137 moves downwardly after such sev- &

erance it will carry the severed portion of the wire, which is to form the staple down with it until the middle portion of such piece of wire comes into engagement with the bar 140 that is projected through the guide-way and plate 135 into position under the wire, see Figs. 3 and 6. The plate 137 has a slot 1 12 into which said bar 1A0 projects and which is wider than the bar 140, see Fig. 3, so that as the plate 137 pushes the cut wire 1 11 downwardly, it will be bent into the form of a staple over the bar 140, as seen in Fig. 3, the two arms of the staple being substantially the same length and both beveled at their ends.

The movable cutter and former 137 is actuated by the lever 150 that projects through the slot 151 in the side wall of the guide frame 85, see Fig. 8, and is pivotally connected therewith by the pin 152. Said lever 150 is fulcrumed on the pin 153 which is secured to the flange or plate 124-, see Figs. 1 and 2. The lever 150 has at its rear end a downwardly extending portion which carries a roller 154 that rides upon the cam 155 secured on shaft 126. At each revolution of the shaft 126 the lever 150 will be operated so as to force the plate 137 down to cut off and bend a staple. The lever 150 is returned by the spring 156 which is connected at its lower end to the pin 152 and at its upper end to the frame 85 at 157, see Figs. 2 and 5. The rear wall of the guide frame 85 is cut away at 158 to permit the vertical movement of the pin 152, see Fig. 8.

After the staple 1 11 has been cut and formed and the moving knife and former 137 moves upwardly from the position shown in Fig. 3, the bar 1 10 is withdrawn rearwardly to disengage itself from said staple. Said bar 141-0 at its rear end is pivoted to an arm or crank 160 on the shaft 161 that has bearing in the rear flange 87 on the guide frame 85, see Fig. 6, at one end and at the other end in the bearing 162, and is actuated as shown in Fig. 15. At its outer end said shaft 161 has an eccentric 163 on it with a pin 164 projecting into a cam and groove 165 in the cam disk 166 secured on the shaft 126. At each revolution of the shaft 126 and disk 166 the bar 140 will be moved into the positions shown in Figs. 6 and 8. hen the staple 141 is thus disengaged it drops into the dotted line position shown in Fig. 3, that is, into an oppositely located pair of grooves in the pair of guide blocks 17 0 fastened on the table 21, see Figs. 1 and 3. These blocks 170 hold the staple in position to be driven downwardly by the staple driver 91 when it moves downwardly.

Below the table there is a slotted guide 172 that projects down to the broom 35 when it is in position and by this means the staple 141 is guided in its downward movement. After the broom has been moved into position to receive the staple, as in Fig. 4, the

staple driver 91 descends and forces the staple through the metal band 36 and the broom corn or other material of which the broom may be formed. It is observed that the means for severing the staples so severs them as to leave their points oppositely beveled. After they are driven through the upper part of the broom and as they engage the lower side of the metal band 36 which rests firmly upon the metal table 38, the band 36 bends or deflects the pointed ends of the staple so that they turn backwardly into the broom fiber and clamp and grasp the same. hen the desired number of staples have been driven thus into one side of the broom, the broom is turned over and staples driven into the opposite side thereof, so that a very strongly constructed broom may be made by this machine. At each revolution of the gear wheel 61 a staple is severed, bent and driven into position. The parts are so arranged relative to each other that a staple is severed and bent while the staple driver is in its upper position and so that it remains in its elevated position long enough for the wire to be fed in, severed and formed and the bar 1 10 to be withdrawn out of the path of the staple driver.

lVhat I claim as my invention and desire to secure by Letters Patent is:

l. The combination of a guide frame forming a guide-way, a stationary cutter plate secured in said guide-way with a central groove in the face thereof, and a cutting ledge at one side of said groove, means for feeding the wire into and across said guide-way against the face of said stationary cutter plate and across the groove therein and upon the out ting ledge thereof, a movable cutter plate in said guide-way adjacent to said stationary plate with a groove in the face thereof registering with the groove in the stationary plate and having a cutting edge for severing the wire, means for bending the piece of wire after it is cut, and a staple driving bar reciprocatory through the opening formed by the grooves in said cutter plates.
