Application filed July 23, 1906. Serial No. 327,272.,

T all whom it may concern:-

Be it known that I, CARL E. JoIiNsoN,a subject of the liing of Sweden, residing at Randolph, in the county of Norfolk and State of Massachusetts, have invented new and useful Improvements in Machines for Making and Driving .Tacks in Window- Sashes, of which the'following is a specification.

The object of this invention is to provide a machine for making and driving fasteners for holding glass inposition in asash before the putty ls applied thereto. This device is to be used in manufactories where large quantities of glass are set in sashes.

The object of. the invention is further to rovide a device of the character hereinefore set forth which will be convenient and quick in its operation and which will result in the saving of a large amount of time and also a saving inthe cost of the fasteners by which the glass is attached to the sash.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly'pointeil out in the claims thereof, V

Referring to the drawings: Figure 1 is a front elevation of my improved machine for making and driving fasteners showing a portion of a sash in section and in position to have a fastener driven therein. Fig. 2 is a side elevation as viewed from the left of Fig. 1. Fig. 3 is a section, partly in elevation,- taken on line 3-3 of Fig. 1. Fig. 4 is a see- I tion, partly in elevation, taken on line-44 of Fig. 2. I

Like numerals refer to like parts throughout the several views of the drawing .In the drawings, Sis a casing or frame sultably formed to be held in the hand of the op erator.

9 is a raceway extendinglongitudinally of said casing, through which a wire 10, from which the fasteners are made, is fed. The wire 10 is coiled upon reel 11, rotatably supported uponthe' pointed ends of screws 12, 12. Said screws are su ported inarms 13, 13 upon the upper end 0' the frame 8 and are locked in position by nuts 14, 14.' The wire is fed downwardly by means of two feed rolls 15, 16. Each of said feed rolls hasratchet teeth formed upon its-periphery, the feed roll 16 engaging a s ring stop pawl 17 which prevents said ro from rotating in the The roll is rotated in the direction of the arrow thereon (Fig. 3) bya pawl 18 pivoted to a slide 19. A reciprocatory motion opposite direction to the arrow thereon (Fig. 3

is imparted to the slide 19 by a bell-crank lever 20 pivoted'upon a stud 21 which is fas tened to an arm 22 integral withthe frame 8.

The bell-crank. lever 20 has two arms 23 and 24. Thearm 23 is connected by a link 25 to the slide 19 and the arm 24 is connected by'alink 26 to a lever 27 pivoted at 28 to the frame 8. The lever 27 is rocked upon its pivot bya lever 29 pivoted to a stud 30 fast to the frame of the machine. The. lever 29 has a cutter 31Qfast thereto which coacts' with a stationary cutter 32 fastened to the frame 8 to sever a portion of the wire 10 therefrom, said portion so severed constituting a fastener 33 (Fig. 4) which is,;-subsequently driven into the sash 34, as hereinafter described. The'fastener 33 is driven into the sash 34' by a driver 35 which is adapted tobe moved transversely of the raceway-9' by a slide 36 to which it is fassaid frame to accommodate different thicknesses of sash.

Having thus specifically described my invention, I will now proceed to describe the general operation of the same: The machine is placed upon the glass 42 of the sash 34, with said sash projecting between the gage 39 and the right hand side ofthe frame, as.

shown in Figs. '1 and 4. Assumin the parts to be in the position illustrated in igsf 1. and 4, the operator grasps the frame 8 and presses the up er end of the lever 29 toward said frame. hen the lever 29 is thus rocked from the osition shown in full lines "Fig. 4 to that ilustratedin dottedlines therein, the lever 27 is also rocked upon its pivot and through the link 26, the lever 29 1s rocked upon its pivot, the arm 24 b'elng moved toward the ri ht, Figs. 1 and 4, and thus through the lin 38 moving the driver 35 toward the right, Figs. 1 and .4, and driving the fast'enerinto the wood of the sash 34.

The wire 10 is fed'during the movement of the parts just described bythe'arm 23 of the lever which moves upwardly, thus moving the link 25 upwardly, ,as well as the .slide 19' and pawl 18, until said pawl engages the teeth of the ratchet Wheel 15 and rotates saidratchet a portion of a rotation in the directionof the arrow, Fig. 3, thus; feeding the wire 10 downwardly.. 1 Continued upward movement of the pawl 18 causes the point of said pawl to pass. out of engagement with and beyond the'ratchet feed wheel. 15 in an idle movement and durin this time the cutter 31 cooperating with t e cutter 32'cuts a fastener 33 -fromthe end of the wine 10, said fastener dropping downwardly-in theiraceway 9 on the upper face of the driver 35 which at that time is beneath said raceway and is driving the next previously formed fastener. As e ,driver 35 retracts toward the left, Figs. 1 and i, until it reaches the po-- position shown in dotted lines tothe position.

shown in'full -lines', that is, into l ahorizontal position lying upon the'upper'face of the glass in readiness to be driven by the .driver 35 which is moved toward the right when" the lever-29 is rocked upon its pivot, the'upper'end of said leverbeing pressed toward .the frame by the operator. as hereinbefore moving the same positively" may shown in described.
