No. 851,996 Claims priority, application Sweden Nov. 13, 1958 2 Claims. (Cl. 8510) This invention relates to nails and structures thereof.
Nails intended to be driven into hard material should preferably have a small diameter and a small head. Nails of this type, however, have a tendency to deform making it ditficult to use the nails without special nailing apparatus.
Nails having a small diameter may be manufactured of Wire in such a manner that one end portion of the wire is bent at a right angle to form a nailhead and the other end portion is pointed to facilitate penetrating the articles to be nailed.
The invention is based on the fact that a nail driven through a guide channel having a diameter about twice as wide as that of the nail tends to deform in an undulatory manner when it is forced against hard material. In order to control this undulatory deformation, the nail according to the invention is manufactured in such a manner that it is divided into several sections each of which may be subjected to a relatively heavy load without tending to deform.
The nail according to the invention is intended to be fed into a guide channel in a nailing machine. It consists of a shaft suitably pointed at one end and of a nailhead bent at a right angle at its other end. The nail has the center position of its shaft bulged out in such a manner that, the nail abuts at at least two points against the one guide channel wall and at at least one point against the opposite guide channel wall.
One object of the invention is to provide a nail of the type described which may be subjected to a relatively heavy load without deforming.
Other objects and advantages of the invention will become apparent from the following description taken in connection with the accompanying drawings in which:
FIG. 1 shows an embodiment of the nail according to the invention both in starting position and driven downwards in a guide channel provided for this purpose in a nailing machine;
FIG. 2 shows a part of a nailing machine according to the invention and comprising a guide channel for the nail and a striker; and I FIG. 3 shows, in perspective and partially broken away, a complete nailing machine according to the invention.
The nail in FIG. 1 comprises a shaft 1, one end 2 of which is pointed and the other end 3 of which is bent at a right angle to form a head. The center of the shaft 1 is in the form of a V-shaped bulge 4. The nail is formed in such a manner that its head 3 and point 2 are located in a guide channel wherein initially the bulged center of the shaft is accommodated in a widening or recess. Due to its aforesaid form, the nail is maintained safely in its starting position and prevented from turning on its longitudinal axis. The nail is preferably manufactured of flat rolled wire.
As shown in FIG. 1, the shaft portions next to the nailhead and pointed end are also somewhat bulged in the same direction as the center of the shaft. During the nailing operation, said center 4 of the shaft is pressed inwards somewhat, the end portions of the shaft necessarily having bulged shape in order to be at least approximately parallel with the nailing direction after said center of the shaft is pressed inwards. It is of vital importance that the shaft portion next to the pointed end must be approximately parallel with the nailing direction, in view of the fact that a nail driven into an article to a certain extent tends to continue penetrating in the initial direction even if the subsequent shaft portion is waved and curved.
FIG. 2 shows a nail according to the invention after the feeding of the same into a nailing machine of the invention. Said nailing machine comprises a guide channel 5 and a nail driver which consists of a slide block 6 provided with a projecting striker 7. The striker 7 is connected with said slide block 6 via a narrow web 8. Said striker 7 and web 8 form an L-shaped projection on said slide block 6 which is disposed in a separate guide channel 9. The striker 7 is shaped in such a manner that it fits into the guide channel 5 for the nail, said channel 5 further being provided with a slot 10 corresponding to said web 8. The nail driver is further provided with external means (see FIG. 3) for moving the driver into its lowermost position thereby to carry out the nailing operation.
A recess 11 provided in the guide channel 5 in the place where the nails enter the channel from the magazine, is formed in accordance with the bulged center bit of the shaft so that before'the commencing of the nailing operation the nail is held in a certain position. In this position the nail is abutting against the back Wall-seen from the magazine-of the guide channel 5.
FIG. 3 shows that the complete nailing machine comprises a magazine 12 from which the nails are fed into the guide channel. Said magazine comprises a longitudinally extending supporting bar 13 intended to support the nails assembled in a row, said supporting bar 13 being shaped in such a manner that it corresponds to the type of nails used. The nails in the magazine are in known manner moved forward automatically to the guide channel through which they will be driven during the nailing operation, the feeding being effected nail by nail at that portion of the guide channel at which the channel is provided with the aforesaid recess 11.
The nailing machine further comprises a substantially cylindrical casing 14 encasing the guide channel for the nails, the nail driver displaceable in the guide channel and the guiding means for the nail driver. A manually operated driving member arranged at the upper portion of said casing 14 comprises a cylindrical portion 15 having a head 16 provided at its outer end, said cylindrical portion 15 being slidable in said casing 14 and having at its lower end a projecting pin 17 to the free end of which the nail driver is fastened. A spring 18 encircles both said pin 17 and the nail driver and abuts with its upper end against said cylindrical portion 15 of the driving member and with its lower end against a supporting disc 19 disposed in the interior of said casing 14. Said disc is placed just above the delivery opening of the magazine and serves at the same time as a guiding means for the nail driver. The cylindrical portion 15 of said driving member has at its inside end a flange 20 which surrounds said pin 17 in such a manner that a space is formed between the pin 17 and the flange 20 which space receives the upper end of said spring 18. Said spring 18 maintains the driving member in projected position as long as the machine is not operated, the free end of the nail driver at the same time being somewhat above the delivery opening of the magazine, so that a nail to be driven into the articles to be nailed together can be fed into the guide channel.
FIG. 3 shows the nail driver in a position in which a nail was just severed from the nail supply in the maga! zine and has commenced its passage through the guide channel. The dash-lines indicate the nail driver in its lowermost position in which the nail is driven to its full length into the articles to be nailed together.
The nailing machine described may be operated manually or by a pressure medium.
At the beginning of a nailing operation, the nail driver is forced downwards in such a manner that the striker 7 separates one nail from the front edge of the nail supply. When the nail is pushed downwards into the guide channel, the bulged center bit of the shaft glides out of the recess in the channel. The nail is thus somewhat straightened and during its subsequent passage through the guide channel pressed against the two parallel opposite channel walls, owing to the resilience of the nail material. In view of the bulged shape of the center bit of the shaft, the lateral. bending directions of the nail are determined, and in the forward or backward direction, seen from the magazine, no appreciable pressure can occur.
As already pointed out, it is of essential importance that, after the nail is driven into the channel, the shaft portion next to the pointed end must be about parallel with the nailing direction because otherwise the nail would penetrate the articles to be nailed together in an oblique direction. It is, however, possible to direct the nail during the nailing operation into a desired particular direction by designing the nail in such a manner that the pointed end forms a certain angle with the nailing direction.
As a further considerable advantage of the nail de-' stantially uniform dimensions along the length thereof,v
said shaft having opposite ends, one of said ends being l of point shape, said shaft including a portion at the other of said ends extending substantially perpendicular to a line joining said ends and in only one direction therefrom to constitute a nailhead, said portion having an end disposed a determinabledistance from said line, an intermediate portion of said shaft in the form of a V-shaped portion extending from said line in a common plane with said nailhead and in the same direction as the nailhead, said V-shaped portion having sides equally inclined with respect to said line and joined at an apex which is located a distance from said line whichis greater thanthe distance of the end ofsaid portion at the other end of said shaft from said line, and shaft portions joining said V-shaped portion and said ends, said V-shaped portion merging with said shaft portions which are also inclined with respect to a line joining'the ends of said shaft, the angle of inclination of the shaft portions to said line being such that the shaft portions become parallel to said line when the nail is driven.
2. A nail as claimed in claim 1, wherein the V-shaped portion is centrally located between said ends.
