The invention is concerned with a nail driving tool preferably operable in pneumatical manner, comprising a magazine for nails composed to form straight rows or straight strips, which nails are successively forced from the front end of a guide, possibly corresponding to the staggered arrangement of the nails, and obliquely terminating into a drive-out channel via a lateral inlet channel into a presenting composition for being, e.g., pneumatically forced out of the drive-out channel. For increasing the magazine capacity while maintaining a handy volume, it is provided that the magazine be formed as a box-type magazine of a width suitable for accommodating two or more nail strips or rows in side-by-side relationship and that the nail strips or rows can be successively forced in a direction normal to the planes of the nail strips or rows into alignment with the inlet channel of the drive-out channel.

1. A nail driving tool comprising a drive channel, a driver reciprocably slidable in said channel for driving nails directed thereto into a workpiece, and a magazine defining a channel cooperating with said drive channel through which successive nails are fed into said drive channel to be contacted
1. A nail driving tool comprising a drive channel, a driver reciprocably slidable in said channel for driving nails directed thereto into a workpiece, and a magazine defining a channel cooperating with said drive channel through which successive nails are fed into said drive channel to be contacted by said driver during each cycle of operation of said driver, means for feeding successive nails from said magazine into said drive channel, said magazine being stationarily disposed relative to said tool and having a width suitable for receiving two or more parallel rows of nails and defining a surface against which the nail rows are forced, said surface being formed by a sidewall of the magazine, and means for biasing the rows of nails in a direction normal to the planes of the nail rows against a surface disposed in alignment with the cooperating channels of the drive tool and magazine and defined by one of said magazine or driving tool, pneumatically operated latch means disposed adjacent the row of nails being fed into the drive channel and positioned to engage the nail row to move a nail into position beneath the driver for repetitive driving of said nails into a workpiece, said latch means are constructed and arranged to move in one direction to positively move nails into the drive channel but are permitted to move in the reverse direction free of said nail row, the latch means comprises at least one latch adjacent the surface and provided on a conveyor cylinder pneumatically operable in the longitudinal direction of the magazine and, if the nails of the nail rows are disposed at a space from one another that the latch can engage between the individual stems, the working stroke of the conveyor cylinder being twice as large as the distance between two nails in the nail row, and, if the nail stems in the nail row are located directly adjacent one another so that it is impossible for the latches to engage between the nail stems, then a respective latch engages behind the backmost nail of a nail row and at least two latches are provided in series in the longitudinal direction of the magazine, the working stroke being at least one nail length greater than the distance from one latch to the next one lengthwise of the magazine whereby a row of nails is in alignment with the cooperating channels of said magazine and driving tool and successive nails from the rows of nails are fed into said drive channel until the magazine is emptied. 2. A tool according to claim 1, characterized in that at least one latch, with a force exerted upon the same from the loading end of the magazine, resiliently gives way, while with a force exerted in the opposite direction, it remains protrudingly arrested. 3. A tool according to claim 1, characterized in that at least one latch protrudes beyond the sidewall of the magazine toward the interior space of the magazine, with the latch engaging between the individual nails or backing up the respectively last nail of a nail strip or row directly forced onto the sidewall. 4. A tool according to claim 1, characterized in that the cylinder is blocked to prevent torsion about the axis thereof. 5. A tool according to claim 1, characterized in that the cylinder is displaceably disposed on a guide rod extending parallel to the magazine. 6. A tool according to claim 1 including an unlockable pawl for backing a nail of the nail strip or row respectively abutting the sidewall. 7. A tool according to claim 1, characterized in that the cylinder is disposed in longitudinally displaceable manner in the guide rail. 8. A tool according to claim 1, characterized in that the guide rail forms a ramp for the nails. 9. A tool according to claim 1, characterized in that secured to the cylinder directly or indirectly, is a tow hook embracing the nail contained in the drive-out channel. 10. A tool according to claim 9, characterized in that the tow hook in the retracted position blocks a release locking nose provided on the tool. 11. A tool according to claim 1 in which part of the magazine is movably disposed relative to said tool and the surface against which the nail rows are forced is formed by a guide defined by said tool at the sidewall of the stationary part of the magazine. 12. A tool according to claim 1 in which the tool contains a support member for said magazine means movably supporting said magazine relative to the support member and means resiliently biasing said magazine relative to said support member, whereby a row of nails will be continuously biased against said surface to position a row of nails thereagainst so nails will be successively driven into position relative to said driver to be driven thereby. 13. A tool according to claim 12 in which the magazine includes a member defining a plurality of guide grooves parallel to each other in a longitudinal direction of the magazine and supporting the rows of nails by their heads, and means for resiliently biasing said member against the surface in alignment with the cooperating channels of the drive tool and magazine, whereby a row of nails will be continuously biased into position so that individual nails will be continuously fed into position to be driven by said driver.
