To all whom it may concern:

Be it known that .wefREINHOLD R. QUICK- ERT and KNUT LARSON, citizens of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certainnew and useful Improvements in Nailing and stapling Machines; and we do hereby declare the following to .be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use'the same.

Our inventionrelatesto nail and staple driving machines .for fastening the ends of hoops or other similar work, and has for its some parts broken'away.

object to improve'the construction with a view of increased convenience, economy, and' capacity.

To these ends our invention consists of the novel devices and combinations of devices hereinafter described, and defined inthe claims. v V

The invention is illustrated in the accompanying drawings, wherein, like letters referring to like parts throughout the several views Figure 1 is a chine, looking from the right, with some parts broken away.

Fig. 2 is a perspective view of Fig: 3 is a, right-side elevation of the machine with Fig. 4 is a detail, partly in horizontal section and partlyin plan, showing the relation of the nail and staple feeding devices to the devices for holding the same in driving position, with all of the said parts in their normaljrpositions, as shown in Figs.1-and 2. Fig, 5 is a View similar to. Fig. 4, but with the staple-feed plunger in its outermost or delivering position. Fig. 6 is a view similar to Fig. 4, but with all the parts in the positions shown in Fig.3 or as they would appear at the initial part of the driving ,ac-

tion. Fig. 7 is a detail in perspective, show ing the outer end of the staple-feed plunger.

as wound about the pivot-pin f i of the lever with one arm bearing against a stud f on the lever, and the other hearing against the forward wall of 'the holder. The said lever f carries near its lower end a bifurcated or two-pronged nail-holder f which works in a slot of the said leverf and is pivoted thereon by a pin f so located with respect to the holder f that gravity will tend to throw the. bifurcated or pronged ends of said holder ff into their uppermost position, as shown .in Fig. l. The said lever f is curved-slightly rearward at its lower end and provided on the rearwardlyprojecting portion thereof with a V notchf 9 for cooperation with the prongs of the holder f to holdthe nail y in its uprightposition, as shown in Fig. 3, when ready for the driving action of thehanimeiz.

\Vhen'all the parts are in their normal position, as shown in Figs. 1 and 2, the prongs of the holder f will be in position to receive a nail from the -stationary section g of the nail-feeding magazine 9 g g*. .The said stationary section 9 is fixed by screw g or-other wise to a lug b projecting from .the framecasting. The section 9 of the nail-feeding magazine is secured by rivets g or otherwise to the forward end of a stiif. flat spring 9 the rear end of which is made fast by screws g or otherwise to the projecting lug b of the frame-casting. The said magazine-section gv and the said section 9 are set on an incline of substantially the same pitch and have top slots or guideways for the nails y, which are adapted to register with each other at the joint betwee rthe said sections 9 g when the driver is in its lowermost position or, more accurately stated, at all times except when the driver is in its uppermost position. The said spring thus tends to hold the lower end of the section 9 in its inner position withthe lower end of the nail-slot of,.said section g in registration with the slot of the section g, but the driver-bar c is provided with a cam-lug c on its rightface, which under the upward movement or the said bar is adapted to engage behind the forward endofi the sec- 'shown in Figs. 1, 4, and 5.

4, and '5 with Figs. 3 and 6.

-'The upper magazine-section g is of boxrlike form, havingitheforward portion .of its bottom plate 'set on an incline andprovidedwit-h a central-slot or guidewayfor the nails which registers constantly with the-upper end of l the nail-slot in thc'section'g.

For, the purpose-of"simplioity'ofistatement the device's for feedingyholding; and driving the nails y have been traced through to their -fina1 result without detailing the staple feeding and holding'devices.

These will now be specified.

To the left side of the frame-casting i s fiixed in an inclined position a-staplemagazine, which is in the form of a guide-rail h, c urvin position to'deliver the .staples mto the forward end of ahorizontal feed-plungerh'. The

The plunger h is mounted and guided by a suitable horizontal seat in the frame-casting and is held from lateral displacement therein. The said plunger h is normally held in its rea'rmost position by a spring h con-' necting the same tothe frame-casting, but is provided with a finger-pull 7?, by means. of which it may be thrown forward against the h for delivering the staples, one at, a time, to the staple-holding devices h h on'the holder-headf. The holder-, head f hasits' left side I plate 'cut away,- as shown at h in Fig.2, for permitting the plunger h to move The outer end ofthe plunger h is provided on its left face with a raised surface h of the propersize to receive one of the staples mand'with atop lip or flange h, under which the staple rests when on the-surface 7L9, as shown in Fig. 2. The space between the plunger hand the delivery end ofthe rail his such that only a single staple can be delivered at a time to the plunger. The surface If on the plungerh is set back a short distance from the outer end of the plungerfiso as to permit the plunger readily to enter between the inner end of the spring-finger-h carried on the holderhead, and pass behind the spring-hook h, the hook end of which is curved laterally inward toward the center of the holder-head f and works through'a slot 71 1 in the finger h.

The raised part h on the plunger his provided with a beveled or cam surface h extending from its lower margin upward near to, but stopping short of, the upper corner of said surface h", so as to leave the-upper foroutward beyond the cam-surface h. In virtue of the said details at the outer'end-of the plunger h and the construction and relative position of the parts h and k on the holder-head f the said plunger h can be made to deliver the staples ac to the parts If and 7;. Under the outward movement of the plungerh the staple will be carried in behind the finger h and the springhook 7'6 the cam-surface h forcing the hook 7L7 laterally'outward through the slot h of the finger h until the a staple has passed by the inturned hook end of the part 71 Then when the said plunger h is released by the operator and is retracted by the spring hitie inturned lip of the hook 71 will ride against the surface 71,

In the manner thus described the staples can be delivered one at a time to the holding devices h? 72 at the left head f, and the said staple will then beheld by the said parts h andh'? in proper position for driving, as shown in Fig. 6. The lower end or head of the hammer c is of sufficient :width or area .in cross-section to cover the staple and the nail when held on their respective holding devices within the holdera.

head f. Hence it is possible to drive a staple and a nail at one andthe same time, and this use would be made of the machine at the last stroke of the driverwhen using the machine for making hoops. On thedownward move-. ment of the driver the Hammer acts with a camm'ing action on the hook h", thereby causaccurately stated, forcing the staple past'the hook in the driving action.

'With the said mechanism above described the staples may be in the same way as the nails by the common driver under the treadle action.

. ,It is of course obvious that the staple-feeding mechanismis normally idle, and hence that-under the treadle action nails will be driven without driving a staple except when the staple-feed device is operated by the hand of the operator. Nails may-therefore be driven without driving the staples. By rendering the nail-feeding mechanism inoperati've in any way it is also obvious that staples may be driven without driving nails. The

' nail-feed may be prevented-without changing side of the holderstaple or, more' 7 fed to the staple holders. h k 'at the will of the operator and be driven the mechanism by holding back the column by simply placing a finger over the stationary section 9 may, however, be readily rendered. inoperative bysimply removingthe cam-lugc, carried onthe driver-bar lateral movement of the magazine-section g.

Hencefwith this machine nails and staples can either be simultaneously or independentlydriven at the will of the operator.

It will be understood that many of the details of the constructionmight be changed without departing from the spirit of our invention; I L
