Abstract
Abstract A device for setting wall anchors and analogous objects has a head portion provided with an exposed surface, and an elongated magazine portion connected with the head portion and extending rearwardly away from the general plane of the exposed surface, being inclined thereto. Guided in an internal guide passage of the magazine portion is a strip of objects to be set, the strip having a substantially step-shaped configuration and the objects being arranged in longitudinal parallelism. The surface is provided with a channel which is open at the surface and also at the guide passage so that the strip will feed under the influence of gravity towards the channel and the respectively leading object will be located in the channel partially projecting beyond the surface whereas the following object will be located laterally adjacent to it.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
177 words
A device for inserting wall anchors, bushings, dowels and analogous objects into existing holes, comprising a head portion provided with an exposed surface adapted to face an existing hole in a structure; an elongated magazine portion connected with said head portion and extending rearwardly away from said surface at an inclination to the latter, said magazine portion having an internal guide passage adapted to receive a strip of parallel connected elongated objects which travel by gravity along said guide passage in a direction towards said surface; a channel extending inwardly from said surface and open to said guide passage, said channel being adapted to receive the leading object of said strip, and said magazine portion and said surface being inclined relative to one another at an angle such that the leading end of said leading object projects outwardly from said channel beyond said surface upon entry of said leading object into said channel, whereby to permit alignment of said leading object with said existing hole; and driving means for driving said leading object into said existing hole.
Claim 2
Independent Claim
177 words
A device for inserting wall anchors, bushings, dowels and analogous objects into existing holes, comprising a head portion provided with an exposed surface adapted to face an existing hole in a structure; an elongated magazine portion connected with said head portion and extending rearwardly away from said surface at an inclination to the latter, said magazine portion having an internal guide passage adapted to receive a strip of parallel connected elongated objects which travel by gravity along said guide passage in a direction towards said surface; a channel extending inwardly from said surface and open to said guide passage, said channel being adapted to receive the leading object of said strip, and said magazine portion and said surface being inclined relative to one another at an angle such that the leading end of said leading object projects outwardly from said channel beyond said surface upon entry of said leading object into said channel, whereby to permit alignment of said leading object with said existing hole; and driving means for driving said leading object into said existing hole.
Claim 3
Dependent Claim
41 words
A device as defined in claim 1, said guide passage having an outlet opening to which said channel is open, and said channel having a discharge opening at said surface; and wherein said openings are located substantially in a common plane.
Claim 4
Dependent Claim
13 words
A device as defined in claim 1, said driving means comprising impacting means.
Claim 5
Dependent Claim
33 words
A device as defined in claim 1, wherein said guide passage is bounded by smooth wall surfaces to that the strip of articles may feed towards said surface under the influence of gravity.
Claim 6
Dependent Claim
99 words
A device as defined in claim 1, wherein said channel has a width sufficient to accommodate the object following said leading object when the latter is received therein, said following object being arranged in longitudinal parallelism with said leading object laterally adjacent thereto and longitudinally offset rearwardly thereof, and said following object arresting said leading object, said following object being adapted to abut said structure as said leading object is driven into said existing hole, whereby a shearing action is produced at the edge of said existing hole so as to disconnect said leading object from said following object.
