A further object of the invention is to provide a novel and improved stapling machine in which a novel mechanism is employed for compressing the impact sprino and for Vadvancing the succeeding staple Following each is impact operation for driving the previous staple.v A

A. still further object of the invention is to provide a novel and improved stapling machine in which the staple supporting member is movable with respect to the frame of the stapling machine so as to properly guide the staple in its proper course into the work.

These and other objects are accomplished by providing a construction and an arrange- Y ment of the Various parts in the manner hereinafter described and particularly pointed out in the appended claims. s

The present invention is directed to a simple7 eiicient and compact motor driven lsatalpling machine and in illustratin one emiment of my invention, I have s own'the same as comprising two sida frame members or casing covers 11 and 1 g preferably secured together by means of transverse screws 13. These casing members are provided with a longitudinal apertured portion 14 so as to form a handle or hand rip 15 forthe purpose of conveniently ma ing the tacking dev ice portble and easily manipulated in varions positions.

Rotatably mounted on a shaft 16 mounted in suitable bearing apertures'l? in therespective side casing membersl 11 and 12, 1s a worm wheel 18 which meshes with and is operatively driven b a worm 19 which in turn is secured to a rive shaft 20 mounted in suitable spaced apart bearings 21 secured to the casing m'ember 11. Secured to the opposite sides of the worm wheel'18 by means of a pin 22 are two lifter arms 23 and 24 which 'are adapted to engage a transverse bar 25 secured to the reciprocating or driving member 26 by means of screws 27. The reciprocating or impact member is reciprocally mounted 'in' a substantially rectangular recess 28 formed in the face block 29 which in turn is secured between the side frame members 11 and 12 by means of rivets or screws 30. The driving member 26 is'provided with guiding ribs 26 which engage complementary grooves 27 in the block 29. The transverse bar 25 is secured in a recess 31- formed on the rear side of the driving member 26. Formed in the longitudinal center of the top of the driver as indicated at 32 is a socket in which is mounted a compression or impact spring 33. The lower end of this spring is seated in the socket'32 while the upper end of the spring surrounds a downwardly extending pin 34 formed on the top side of one ofthe casing members. Formed integrally with the driver and preferably on the rear side thereof, is a rearwardly projecting lug 35 which is adapted to be engaged by a reciprocating pawl or latch 36 mounted to slide in spaced apart bearings 37 secured to one of the side casing members. The forward end 0f the latch 36 is bevelled as shown at 38 to permit the projecting portion 35 to de ress the latch backward on the upward stro te of the driver compressing the impact spring 33. This latch is normally pressed into engagement to lock the driver in elevated position or the position shown in Fig. 1 by an extension spring 39 which has one end thereof engaging a pin 40 and the other end thereof, as shown at 41, enga ing'the rear bearinv 37. The latch is normal y moved rearwardlD to disengage it from the rearwardly exten ing rojection 35 by means of a depressible mem- Ber 42 which is provided on its lower end with a bevelled or wedge shaped portion 43 which in turn is adapted to engage acorresponding bevelled collar 44 secured to the rear end of the latch member 36 by means of a pin 45. The reci rocable member 42 is reci rocally mounted) in an apertured boss 46 ormed on one of the casing members and has its up er end provided with an enlarged head 47 wiiich is positioned within easy reach of the operator so that the same may be manipulated by the thumb as the handle is gripped by the operator. Secured in a recess 48 on the front face of the driver mem ber 26 by means of a screw 49 is a driver bar 50 which is preferably made of hardened steel. This driver bar 50 is adapted to reciprocate in vertically extending Grooves 51 formed in the lower end of the face block 29. The drive shaft is driven by a flexible shaft 52 which is secured through the medium of acollar 53 to the casin members. The flexible shaft, of course, is riven by a suitable motor.

` From the above description, it will be seen that as the shaft 20 is driven in a direction to drive the worm wheel 18 in a direction in dicated by the arrow that the revolving lifter arms 23 and 24 will engage the transverse bar and elevate it to the full line position weerman am shown in Fig. 1, where it will be locked by the latch 36 engaging the rearwardly extending projection compressing the spring 33 so that when the depressible member 42 is depressed by the thumb of the operator and the latch 36 withdrawn rearwardly, the

Another essential feature of my invention comprises the method of automatically feed.-

ing the next successive staple into position and the means for properly guiding the staple during the driving operation so that it is driven vertically and properly into the work. This mechanism comprises a staple supporting bar 54 which is pivoted at 55 on a pin extending transversely through the casing members. This staple supporting bar is provided with a recess 56 on the lower side thereof, in which is mounted a looped flat spring 57 which has an eye formed on one end thereof as shown at 58 and secured to the recess by means of a pin 59. The lower or free end of this looped spring 57 is adapted as shown at 60, to engage the bottom portions 61 of each of the side plates or casing members 11 and 12. The movement of the staple supporting bar 54 is limited in its upward movement by reason of the rear end of the bar contacting the bottom portion 61 of the casing members as indicated at 62. Formed on the opposite sides of the front face bar 29 are two recesses 63 which forms the guide for engaging the opposite sides 64 of the staple 65 about to be driven. These staples 65 are the conventional form of staples now in general use and are arranged in strips as illustrated in Figs. 1 and 7 of the drawings and are supported on or straddled over the staple supporting bar 54. On the movement downwardly of the staple driver the lower end 66 contacts with the upper surface of the staple that is in a position to be driven and depresses the bar 54 downwardly about its pivot 55 against the tension of the spring 57 from theposition shown in Fig. 1 to that shown in Fig. 7, at which time the free or front end of the bar 54 contacts with the bottom 61 of the casing members as shown at 67 and on a further movement of the driver 50, the rear edge, of the drivers as shown at 68 severs the staple or tack on the forward upward edge 69 of the bar, but just previous to this severing operation the lower point 70 of the staple enters the grooves or guides 63 to prevent the staple from turning or twisting so that the same is properly driven vertically downwardly during the severing and driving operation of the sta le.

nother important feature of the present invention includes a novel means and mechanism for feeding the next successive staple into position to be severed and driven in cornbination with the mechanism for compressing the impact spring. 'This mechanism comprises a novel springactuated lever 71 which is pivoted on a shaft 72 which in turn is journaled in the side frame or casing members 1l and 12 in any well known manner. This lever is normally actuated to .theposition shown; in l Fig/1l ybyafiat,spring173.which has one end .,thereof-v secured-to. xai ltransverse. pin which;y

in turn, is secured tothe side casing members 11 and 12 in any well known manner. The free end of this spring 73 is secured in a slot l75 formed in one side of the lever 71 to normally actuate the'lever to a position shown in Fig. l. The upper end of the lever 71 is provided with a cam projection 7 6 which is located in the path of one of the revolving arms 24 as clearly shown in Fig. 5, so that on the initial upward stroke of the arm 24, following the downward stroke of the driver, the lever 71 is actuated to the position shown in Fig. 5 and as the arm passes the cam 7 G on the lever 71, a bifurcated pawl 77 pivoted at 78 to the lower end of the lever has its free end, as shown at 79, engaging the. opposite recesses, as shown at 80, between the staples 65 and on account of the tension of the flat spring 73 the next succeeding staple is moved into position for the next operation of the severing and driving of the next succeeding staple. At the same time, it will be noted that by reason of the spring 57, the staple supporting ,bar 54 is raised to its elevated position as shown in Fig. 1y to be in position for the next cycle of operation of severing and driving the next staple.

From the above description it will be readily seen that if the controlor depressible member 47 is held depressed, that these staples may be driven continuously or if it is desirous to drive them intermittently, the pressure is relieved intermittently from the depressible member 47 and by reason of the latch 36 engaging the rearwardly projecting lug 35 on the reciprocating member 26, the' continuous operation of driving the staple is interrupted without, however, interrupting the driving mechanism such as the worm wheel and drive shaft. But it will be noted that immediately on the depressing of the control 'member 47 a staple is driven and staples thereafter may be continuously driven while the control member is held depressed and interrupted only when the pressure is released from the control member.

From the above description, it will be seen that I have provided a novel, simplified and compact automatically actuated stapling machine which will continuously or intermittently drive tacks at the Will of the operator and by reason of its lightness in Weight, permits the same to be used in various positionsy and for manyfold purposes.

While in the above specification, I have described one embodiment which my invention may assume in practice, it will of course be understood that the same is capable of modification and that modification may be made without departing from the spirit and scope of my invention as expressed in the following claims.
