SPECIFICATION forming part of Letters Patent No. 633,764, dated September 26, 1899.

Application tiled April 28, 1899. Serial No. 714,806. (No model.)

To a/ZZ when?, it 77u01/ concern:

Be it known that I, JOHN LJUNG, a citizen of the United States, residing vat Nelson, in the county of Douglas and State of Minnesota, have invented a new and useful Nailing-Machine, of which the followingis aspecication. I

This invention relates to nailing-machines, the object being to provide a simple and efficient apparatus of this character which is adapted to carry a large supply of nails to be furnished for use as required, thereby avoiding the necessity of placing them in the mouth or in the pockets, and the nails can be readily fed one by one with rapidity to theproper point, and bya use of the machine the workman is enabled to wear gloves or mittens in cold weather, and while the machine is primarily adapted for furnishing nails to be used in fastening shingles to roofs and other structures it is apparent that it can be employed with equal advantage in many different arts.

The device includes in its construction nailsupply means and a device for carrying a nail bodily from the same to a position Where it may be struck by a hammer, hatchet, or like implement, and the nail-supply means consists, preferably, of a trough or magazine inclined at the proper degree and a runway communicating with the chute and along which the nails may be pushed by hand and a carrier which is adapted to transfer the. nails bodily from the runway for use as re quired, and this carrier may be of any suit able construction and operated in any convenient manner. ln other wo`rds, the nail carrier or separator grips the individual nail and moves the same to a position isolated from the other mechanism, and thereby provides for holding the nail in a position readily accessible for hand-nailing.

W'ith these ends in view the invention consists in the novel combination of elements and in the construction and arrangement of parts, which will be hereinafter fully described and claimed.

To enable others to understand the invention, I have illustrated the preferred embodiment thereof in the accompanying drawings, forming a part of this specification, and in which- Figure lis a side elevation of a nailingmachine constructed in accordance with my invention. Fig. 2 is a plan view of the machine. Fig. 3 is a rear elevation. Fig. 4. is a detail in perspective of the delivery end of the runway for the nails. Fig. 5 is a detail plan view of the magazinechute- Fig. C is a detail cross-sectional view on the line 6 G of Fig. 5. Fig. 7 is a detail in perspective of the magazine-ch nte. Fig. Sis a detail in perspective of the actuating-lever for reciprocating the nailcarrier. Fig. 9 is a detail sectional view on the line 9 9 of Fig. 2, showing more plainly the arrangement of the supporting device for the magazine-chute. Fig. 10 is a detail sectional View on the line l0 10 of Fig. 2, showing the relative arrangement of the upper and lower guiding-springs associated with the reciprocating nail-carrier.

Like characters denote like and corresponding parts in each of the several iigures of the drawings.

The nailing-machine is intended principally for furnishing nails for use in shingling, and it is transportable, preferably, and should be mounted upon a truck or framing, which latter may be of any suitable construction.

The truck represented is denoted by T, and it consists of two side bars 2, joined at the front and rear by the cross-pieces 3, these parts usually being made of strap-iron and the cross-pieces having upturned ends to support the axles et and et' of t-he truck, which are provided at their ends with Wheels 5, adapted to roll upon a roof or other place as the apparatus is shifted f`rom point to point.

The nail-supplying mechanism includes in its construction an inclined magazine trough or chute (i, having a slot 7 throughout its length, through which the shanks or bodies of the nails project, and provided with upturned vertical side walls b' and'closed at its upper end, as at 9. This inclined chute or trough 6 is provided with the nail-receptacle l0, disposed substantially in a horizontal position and constituting with the chute the nail-magazine and having a closed end l2, in the center of which the vertical slot 13 is formed, the upper end of the slot being widened, as at 13, and the hole being shaped to agree with the `form in longitudinal section of the nail, which is passed therethrough and is advanced toward the na-ilpcarrier or picker to be conducted by the latter to the point of IOO use. The nail-receptacle 10 has a longitudinal slot 14, forming a continuation or prolongation of the longitudinal slot 7 in the chute, and the vertical walls 15 rise from the bottom of the nail-receptacle at opposite sides of said slot 14 and merge on curved lines into the inclined bottom of the chute and divide the nailreceptacle into two compartments or chambers. Thenails pass along the slot 7 and then between the vertical walls 15, their heads being supported by the upper edges of said walls, and they are successively pushed through the T-shaped slot 13 and from thence pass into a runway, from which they are taken by the nail-picker.

The nail-runway, to which reference has been made, is denoted by R, and it consists of two substantially similar or duplicate side pieces or strips 16, one of which is secured to the upturned ends 17 of the side bars 2, while Y the other of which is secured to thevertical strips or bearings 1S, which in turn are secured to said npturned portions 17, and the respective parts are spread or spaced apart above the upper edge of the side pieces 16, thereby to permit the free movement of the heads of the nails which rest upon the runway. The innermostvertical member 18 extends upward higher than its companion and is connected to the diagonal brace 19, which in turn is fastened to the adjacent side bar 2 near the front axle et, thereby strengthening the structure. The vertical upright 1S, to which I have just referred, serves to uphold the locking-standard 20, to which a connection joined to the chute 6 is united.

The inner closed end wall 12 of the nailreceptacle 10 is provided on the outer side thereof and at the opposite sides of the vertical slot 13 therein with the oppositely-arranged pairs of inclined retaining-flanges 21, forming therebetween recesses 21 to receive the cooperating wing's or flanges 22, fitted, respectively, to opposite sides of the runway R at the inner end thereof, said wings 22 being upwardly convergent, so as to register in the recesses between the retainingflanges 21, and thereby providing a rigid detachable joint or connection between the contiguous ends of the magazine-chiite and said runway, whereby the slots of the runway and of the magazine-chiite will remain in precise alinement, so as to form directcontinuations,`

and thereby permit of the free travel of the nails from the magazine and upon the runway to thefdischarging end of the latter.

The standard 20, to which I have hereinbefore alluded, is vertically disposed for the major part of its length and terminates at its lower end in the transverse extension or foot 23, provided at its end with a hook 24, adapted to engage the bail 25 near its middle, and said bail has eyes or openings 26 at its inturned ends to receive the transverse rod 27, supported by the ears 2S on the nail-receptacle 10. The lower end of the standard 20, near its transverse extension 23, its against the projection or cross-piece 29, which con nects the parts 17 and 1S, and it is bent inward and forward near its upper end to forma loop 30, which partially embraces or straddles the part 1S. The said standard is projected upward beyond this loop 30 and is provided with a second and substantially U-shaped bend, the upper branch 31 of which is materially longer than its companion and constitutes the head of the standard and receives the loop or eye 32 at the bend, of the angular connecting-piece 33, one end of said connecting-piece being coiled to receive the stirrup 34, located at a convenient point in the height of the chute 6. The shorter leg of the connecting-piece is provided with a hook 35, adapted to engage in an opening in the upright 1S.

From the foregoing it will be understood that the member or part 18 constitutes a rigid upright support for the magazine-chute, and at this point it is to be observed that the loop 30 of the locking-standard' 2O is sprung into engagement with one edge of the supportingupright 1S, whereby the locking-standard will exert a leverage upon the cross-pin 29, with the latter as a fulcrum, and cause the engaging hook 2-1 to exert a strain upon the bail 25, and thus insure the rigid positioning of the lower end of the magazine-chute, while the connecting piece or wire 33 by reason of its engagement with the upper branch 31 of the locking-standard and also with the supporting-upright 18, as plainly shown in Fig. 3 of the drawings, provides for properly bracing the main inclined portion of the chute. Furthermore, the parts referred to are separably associated together, whereby the magazine-chute may be readily detached from the remainder of the machine or swung to 31.

To load the machine, it is properly grasped and a handful ot' nails are put into the nail receptacle or box 10 when the device is in its normal position, after which the latter is tilted, allowing the nails to slide slowly toward the top of the trough, at which point the nails are momentarily held and slowly freed, so that they may escape in scattered order and run down the trough and pass into the elongated slot 7 until the heads of said nails strike the bottom of the trough. The nails can then pass from the trough between the vertical walls 15, and to prevent their jumping out the stop or arresting device 26a is disposed in their path and is preferably carried by the upper end of the wall 12 upon the inside thereof and consists of a resilient or spring finger adapted to be struck by the foremost of the nails and which permits the nails to pass between the opposing' sections of the runway R, the nails being successively taken from the delivery end of the latter and bodily conveyed therefrom for, use as occasion demands.

The uprights 37 are secured to the two side pieces 1G of the runway extending upward therefrom and being spread apart near said IOO IIO

runway sufficiently as to permit the free progress of the nail-heads, and the U -shaped bar 38 is secured to these strips and also to the outer uprights 18 and extends downward and rotatively supports the axle 39, provided with the guide-wheel 40.

The nail-carrier is denoted by N, and it is reciprocated across the discharge end of the runway transversely thereof and is of such a construction as to pick Ithe nails singly from the runway and advance them to aplace beyond the same, where they may be driven home by a hatchet or like implement, and as each nail is required the machine will be moved forward to repeat the operation.

The nail-carrier N has two lingers 4l and 42, respectively, the working ends of which are in proximity and which are made sufficiently resilient or springy to assure them obtaining a firm hold upon the nails, and said nail-carrier is provided with a slide-loop 423, which embraces and slides upon the guiderods 44, projecting in parallelism from the outer side piece 16 of the runway, said rods constituting a convenient support for the nailcarrier.

The runway has a recess or notch 45,through which the inner branch or finger 4l of the nail-carrier N reciprocates, and said branch has near its end the cut-away portion 46, between which and the adjacent finger 42 the nails are singly received and conducted forward on the working stroke of the nail-picker. By cutting away the inner finger 41, as just stated, a thin springy extension is provided upon the same. The nails are pushed along the runway and the foremost one will abut against the outer finger 42 when the said carrier is in its retracted position, and when the carrier is moved forward the reduced end of the finger will select the foremost nail from the series and will press the same against the outer inger, so that when said carrier or picker is advanced the nail thus held will be moved away from the runway. The terminal portion of the nger 42 facing the portion 46 of the nger 4l is provided with a nailengaging notch 46, which assists in holding the nail between the contiguous ends of the fingers until the machine has advanced.

Associated with the reciprocating nail-carrier 9 is a pair of upper and lower guidingsprings 65 and 6G, respectively. The upper guiding-spring 65 is coiled upon one of the guide-rods 44, as at 67, and has one end thereof fastened to a fixed part of the framework, as at 68, thereby leaving its other end free to exert a spring-pressure upon the nail-carrier N. The said upper guiding-spring 65 is arched over the guide-support for the nailcatcher and has the free terminal thereof depend between the separate fingers or bran ches 4l and 42 of the carrier, and normally the pendent free end of the guiding-spring 65 bears against the spring stop plate or projection 69, which is projected from the outer side ot' one of the guide-rods 44. The lower ot said guiding-springs GG is also coiled, as at '70, upon one of the guide-rods 44 and is secured fast at one end to a fixed part of the framework, thereby leaving its other end free to exert a spring-pressure against the nailcarrier. The main arm of said lower guidespring G6 is arched beneath the guide-supports of the nail-carrier and is normally arrested' against one of the guide-rods 44, as plainly shown in detail Fig. lO of the drawings, and the free terminal of said lower guiding-spring 6G is extended beyond the contiguous guide-rod 44, against which it rests, and is disposed directly beneath the nail-carrier N to prevent downward displacement thereof, while at the same time leaving the nail-carrier suiiiciently loose to insure the engagement thereof with a nail in a manner to be hereinafter fully explained.

lVith reference to the action of the upper guiding-spring 65 it will be noted that the stop plate or projection 69 keeps the spring normally out of engagement with the nailcarrier, especially at the moment the carrier engages the nail and swings the same laterally and outward from the contiguous end of the runway R. When this occurs, the nail-carrier presses outwardly against the pendent free end of the spring 65, and the latter will therefore move the nail-carrier back again to its normal position, so that the nail between the contiguous ends of the fingers thereof will be carried alongside of the longitudinally-disposed guard 71, arranged at one side of the truck-frame. Said longitudinally-disposed guard 7l is provided with a pendent foot portion T2 beyond the discharging end of the runway R, which foot portion constitutes a nail-carrier rest, against which the gripping end of the nail-carrier is thrown as it advances to a position to carry the nail contiguous to the angular ham mer-guide 73, formed in the body of the guard 7l adjacent to the rest-foot 72. At this point it will be observed that the inner finger or branch 4l of the nail-carrier is provided with a deected portion 4l, which rides against the pendent end of the spring 65 and causes the advance end of the nailcarrier to be thrown alongside of the rest-foot 7 2, as indicated in dotted lines in Fig. 2 of the drawings. NVhen the nail has been carried adjacent to the angular hammer-guide 73, the same can be grasped and driven by the hammer without the latter interfering with any part of the machine. It is to be observed that the hammer-guide 73 provides a clearance-space for Ithe head of the hammer in the hand of the operator and permits the nail being moved by the carrier to a position isolated from all other working parts of the machine, whereby itis readily accessible forhand-nailing. In this connection it will also be noted that when the nail has been advanced by the nail-carrierto this isolated position the nail may be started while held by the carrier and then after a slight advancement of the machine-truck the guide IOO IIO

73 will permit the hammer to clear the adjacent parts of the machine without moving the same laterally. The said longitudinally-arranged guard 7l is further provided with a horizontal guide extension 74, arranged in substantial parallelism to one of the guiderods 44 and constituting a part of the guidesupport for the slide-loop 43 of the reciprocating nail-carrier.

.Any convenient means may be employed for reciprocating the nail-carrier, but for this purpose the actuating-lever 47 is preferable, said lever being manually controlled and be ing disposed within easy reach of the workman.

The lever 47, like the nail pi'ckeror carrier N, is preferably made of wire bent to the proper shape, and it has at one end the transverse journal portion 4S, supported for oscillation by the bracket 49, secured at one end to the frame 50, and said bracket is also formed of Wire and has a series of coils to receive the journal or pivot extension 4S. The lever extends beyond the fulcrum and is located beneath the longitudinal horizontal member of the frame and is provided at its end with a longitudinal loop 5l to slidingly receive the projection at the end of the crank 52 on the shaft 53, which is supported by the bracket 54 on the inner end of the frame 50, and said shaft is provided with a second crank-arm 55, coiled at its end to receive the projection at the end of the link 56.

The link or pitman 56, connected with one arm of the crank-shaft 53, is provided at the end opposite such connection with an elongated loop 75, which looselyT engages one end of the slide-loop 43 to provide for the reciprocation of the nail-carrier. The said elongated loop also embraces acontiguous end of an auxiliary starting-head 76, which transfers the initial movement from the link or pitman 56 to the slide-loop 43. The said starting-head 76 is in the form of a cross-head and is slidably mounted upon the rods 44 alongside of the loop 43, and at one end the said starting-head 76 is provided with a stop-arm extension 77, which is adapted to strike against the fixed abutment 7S, iitted to the guide-rods 44 and projected beyond one of said rods to lie in the path of movement of the said stop-arms 77. The function of the auxiliary starting-head 76 is to prevent movement being transferred to the slide-loop 43 of the nail-carrier until the nailhas been firmly engaged in the notch between the contiguous ends of the nail-carrier iingers. nection it will be observed that when the operating-lever 47 is elevated to provide for actuating the crank-shaft 53 the motion from the link or pitman 56 is first imparted to the end of the auxiliary starting-head,with which it engages. This end of the starting-head will be drawn against the contiguous end of the slide-loop 43, and consequently impart a slight rocking movement to this loop, so as to throw the nail-carrier outwardly a sufficient In this con'.

distance to remove the nail from the contiguous end of the runway, after which the nailcarricr advances and is returned to a normal position by the pressure of the guiding-spring 65, as previously explained.

When the operating-lever 47 is lowered, the nail-carrier is drawn back to its initial position, ready to engage with and carry forward another individual nail.

As already pointed out, the operating-lever is grasped by the workman, and the supporting-frame 50 thereof constitutes a convenient handle, as well as assists in maintaining the operator in his position upon a roof, and the said operating-lever is preferably formed of stout wire bent into proper shape and having parallel separate grasp portions 57 and the lower pendent loop 5S, between which the iingers can be thrust while manipulating the lever. The said operatinglever 47 is also provided with an upstanding stop-iingcr 59, adapted to engage beneath the upper horizontal portion of the frame 50 to arrest the upward movement of the lever.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described shingle-nailing machine will be readily understood by those skilled in the art without further description, and it will also be understood that various changes in the form, proportion, size', and the minor details of construction Within the scope of the appended claims may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention.
