B nooMj-STAPLING MACHINE.

To all whom 'it/may concern."

Beit known that we` SAMUEL C. LAY and FREDERICK M. BAKER, citizens of theUnited States, and residents of Ridgeville and Detr'oit, respectively, counties ofRandolphand Wayne, respectively and States of Indiana and Michigan, respectively` have invented a certain new anduseful Vlyroom-Stapling Machine; and we do hereby declare that the following is afull, clear,` and exact'deserip- `tion thereof, reference beinghad to the'accompanying drawings, in which like letters refer to like' parts. The ob'eot of this invention is to provide a broom stapling machine'of as simple con- Ystruction as possible which will properly out the staples,vv form them andY drive thern A further feature s'the ConstructionYof.V the staple formingmechanism and the fdrivfy `ing mechanism lwhere-by the staple Ywill, be

disengaged from the staple former so as toV av'oidity when being driven intothe broom head, thus doingj away with Athe 4Complicated mechanisinusually employed inproviding a disappearing staple former.

Stillanother feature ofgtheinvention is the means for elevating the-broom table so Y as to raise the broomhead ini'position toengage thefstaple driving mechanism.v The broom maybe freely/positioned vby thel opera'- tor when v not being stapled, and when i1 proper position" for the staples; each staple will be driven and clenched instantaneously.' 45

fed into the stapling mechanism, which will be hereinafter described. On the feeding roll 30 there is a cam portion 38 which eX- tends partly around said roll and which will engage the roll 31 when the rolls are turned, so as to force the roll 31 upwardly in itsl sliding bearing 32 whereby the wire will be disengaged and will not be fed into the stapling mechanism until-.the cam portion permits the roll 31 tok rengage the roll 3()v and continue to feed in the wire. It will, therefore, be seen thatv the wire will be fed into the. machine at given intervals and in given lengths depending upon thel size of the cam. For preventing the further movement ofthe wire after it isk released from the rolls/there is provided a clenching device 39 through which the wire mustp'ass before entering the. rolls, which frictionally engages the wire and retains it until the pressure ofV the rolls overcomes the friction and forces it into the machine. The wire is gripped in the jaw of; the device by the tension of the spring 40; which tends to cause the jaw to frictionallyengage the wire, as shown in Figs. 6 and 8.

f The` staple by a cam 41 keyed to the opposite end of the shaftL 13 Vfrom the gear 20. Said cam is adapted to engage the roller 42 on the plun-V ger- 4 3. Said plunger is adapted to recipro- V vcate in ahousing 44 in, which there is a coml whiclris secured to the lever 48.

pression spring-45 whichengages said plunger foi-.returning it to its normal position after having been operated by said cam. On the lower end oftheplunger there-is a shaft 46 which extends downwardly through the compression spring and housing and has on the end. thereof a head 47 said head being in position to engage the staple forminglever- 4,8' when the plunger-is operated. The head 47 rides in a T-slot in the projection 84,

3 Pivotaully mounted on the cam, 41 by the pin 49' there. is: a connecting rod Owhich isv connected t0. the'hanmier 51 by the wrist pin 52. Said hammer is adapted to reciprocate in theihearng 5.3.

' Keyed on;V the shafty 13 thereris a cam V54 whichA is'provided'with a brakedrum adapted to :beA engaged by Athe brake band so Y that'the shaftl willgvstopimmediately upony being released from the driving wheel 14 by the. clutch mechanism. The cam: l54 is in position to engage a, roller 56 onone end vof a lever! 57 Ywhich is, pivotedto the frame at 58,; the other end of the lever extending 'Y so through'a slotin the` end ofthe stapleformf ing lever 48:` so as to. engage. saidV leverrfor forcing* 1t forwardly von its pivot pin 5 9.

The end. of the lever48 is, yieldinglyvv secured to, fthe'frame. by, the spring 60,- which 'will return saidlever 48 after having been operatedv 'byitheflever 57; Thestaple forming end of; the lever 48 is provided with a slot forming mechanism is drivenv which will straddle the staple forming block 61, said lever being provided with a groove 62 on the inner side thereof. The staple wire is adapted to be inserted between the lever 48 and the staple forming block whenit is in thevposition shown in Fig. 3. The lever 48 is then engaged by the head 47 and forced down over the block 61 at the same vtime cutting the wire by the knife'edge 63 from the block 61 and remains in the groove 62 of the lever 48 by the tension of the wire in a position shown in Fig. 5. Wvhenthe machine is in this position the staple is cut and formed and ready; to be driven into the broom head.

Pivoted to thev base of the machine there is a lever 7() having a pin 71 therein adapted to, engage the slot 72 in the drum 73 which is Vsecured-on the shaft 25. The `upper end of the lever 7 0 isA secured to al rod 74 which is pivoted at its other end to the sliding frame 75. The lower end of said frame is curved and adapted to slidably engage the exten' sions 7 6 which have upwardly curved surfaces 77. Pivoted tov the upper portion of the frame75 there isa broom table 78 which is slidably supported onj the frame 7,9 so that when thet frame 75 isforced forward by, meansk of the rod 74 it will engage1 the upwardly curved surface. and force the broom tabler in anA upper position as shown in Fig. 9, and when released the table will drop down to the position shown in Fig. 2,. in which .position a broom mayy be placed thereon and adjusted to the position in which the staple is` to be inserted; andy then lifted upwardly against thestapling `mechanism by said frame when it is ready to be stapled. f .l Y l y Secured inthehammer 51 by means of the set screws 80 there is anextension 81 to the hammer, and adjustabletherein, which, tension 1sl adapted to be driven through the slot in thestiple forming lever 48 so as. to

engage the block and retainthe staple by` means of its spring tension in position shown in Fig. 5. The broom table is then forced in its upper position as shown in Fig. -9 and the hammer 5l causes the staple to be driven into the broom head by'means of extension 81 through the staple guide 83 against Which `the broom is forced by the broom table 78. 4While `.the operation of driving the staple into the broom is going on the staple forming lever 48 is moved inwardly by means of the spring 60 out of the Way of the driving extension 81 and is drawn upward out of engagement with the block 61 by means of the head 47 engaging the projection 84, as shown in Fig. 3. The continued operation of the machine brings a new length of staple Wire in position to be engaged by the staple forming block preparatory to another operation.
