HANDNAIL Canada Oar] Christian Peterson, Burlington, Ontario .Application January 11, 1943, Serial No. 472,058 l i i In 'CanadaSeptemberIO, 1942 e Claims. (cur- 46) This invention relates to improvements in devices for presenting and driving-nailsand consists essentially of a basewith provision fora train of nails and means for urging the train to a position inwhich the leading nail may be driven into the work, and each leading nail thereafter consecutively driven until the train is exhausted, and means for automatically replacing the exhausted train by a successor and so repeatedly until the exhaustionof a certain magazine. The principal object of the invention is to generally improve the construction of automatic hand-nailing machines of the type particularly adapted for finishing nailsand for-such typical work :as driving and countersinking such nails in glazing and panel beading and the like where driving the nails by hand often results in breakage or damage. l
Another important object is to provide means inlsuch a device for conveniently and rapidly recharging the feeding means. K
Another important object is to provide means whereby a recharge of nails may be fed to the feeding means point-down and in line from a dis-.
arranged mass in the magazine.
Another important object is to provide :a device of the kind describedwhich will be simple,
durable, efficient and inexpensive to purchase.
With the above and other objects in .view, as will be hereinafter apparent, the invention consists in general. of certain. novel details .ofconstruction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed.
In the accompanying drawings like characters of reference indicate like parts in the several views, and:
produce and Figure 1 is a top View of an apparatus constructed in accordance withthe present invention. Figure 2 is a side elevation taken on the line 2--2 of Figure 1. i
Figure 3 is a bottom view of the apparatus.
Figure 4 is a sectional top view taken on the line 44 of Figure 2.
Figure 5 is a perspective view of a certain spider and spring housing assembly.
Figure 6 is a partial sectional elevation similar to Figure 2 showing a certain shaft and pusher arm in depressed position.
In its present embodiment the invention consists of a round base l0. havinga tangent-like extension I. Inthe bottom of the round portion of the base is a round opening |2 enlarged at the Secured by screws |1b or otherwise suitably sc out of the groove and re-insertedby areversal of top, the enlargement having an annular groove which'receives the bead l3 of the skirt of the cylindrical nail magazine M. The magazine may beremoved from its seat in'the bas'eby' forcibly tilting it to one side and thereby fiexingthe skirt thesame procedures The magazine contains the nail supply ina disarranged mass MA and is filled through slide openings IS in aclosure caplfi.
Inside the magazine I4 is a spider consisting of a hub having radial arms |'|a extending therel. from; The arms of the spider extend through notches inthe skirt of the magazine to the outside where'they are'bolted or otherwise suitably secured to the upper face of the base section II).
cured to the spidenunderneathis a canopy-like housing l8 for a helical spring l9. One end of the spring is anchored to the internalface of-the housing While the other end is securedto a vertically projecting portion of the hub 20 ofa paddle-like pusher arm 2| which lies beneath the spring. i l M l The nail feeding portion of the machine may be constructed as follows: The hub of the pusher arm 2| is pinned fast on the end of avertical shaft 22 as indicated. The shaft 22 is sleeved through the housing l8, through the hub I1, and
emergesthrough a central sleeve in the cap |6 where it is provided with a handle 23. A spiral expansion spring 24 disposed about the. shaft 22 andcompressedbetween the hub I1 and acollar 25 pinned onthe shaft urges theq shaft and the arm 2| to theworking position shown,-but when the shaft is moved downward against the urge of the spring 24 the bottom of the shaft together with the arm 2| emerges beneath the baseand is ,free to be turned backwardly bymeans of the handle 23 for a purpose that will later appear.
Inmoving-down or depressing the arm 2| and while the arm continues' to be depressed the spring I9 is deformed as indicated in Figure 6,
that is to say the central partof the spring is carried downwardly with the hub 2|] from its nor- 7 mal plane; on the rise of the arm 2| the spring l9 will elastically revert to its former normal position.
The intervening space between the annular housing l8 and the face'of the opening |2 is merely greater than the diameter of the shank. of
the particular nail which the machine is dimen sioned to accommodate, and this space forms an annular passage 26 for a train or bank of nails 21. The curving passage 26 merges with astraight passage 28 the base extension II. It will be noted that the passages are open at the bottom of the base, and the nails are retained by the engagement of their heads on the shoulders of a chamfered enlargement of the passage 28, and in the passage 26 by the bevelled portion 29 of the opening l2 and the converging inclination 3B of the housing |a.1, 'rne passage'zt terminates inan' opening 3! extending th'roughto the top as well as to the bottom of the base.
The nails are lodged point down in the pas having a nail feed passage communicating at a tangentwith an annularlnail 'passageigthe feed passage being adapted to' receive a train of nails and subsequent replacement trains from the annular passage, said annular passage being adapted sage l2 by agitating the device more or lessv-iolently, the pusher arm 2| first having beendepressed or extruded then revolved against the urge of the spring l9, then retracted at a pint close to the junction of the passages 26 and 28* and released. On release of the pusher arnr it, will push all the nails which have dropped'poi-nt- -down in the passage 26 together and against those remaining in the passage 28. Thus the passage 26 is recharged as many times as there are sufiicient nails for the operation remaining in the magazine. t 1
Risingufrom the end part of the base extension it is .a column 3-2; and operating in a sleeve in this column is a, driver shaft 33 having a reduced portion 34. of the proper diameter to penetrate the opening 3| to engage the head of the leading nail of thetrain and to drive it. Moreover, the reduced portion 3| of the driver 33 is of a length greater than the thicknessof the base portion l l sothat the nail as well asbeing driven is countersunk into; the 'material with which the bottom face of the base is engaged by a single stroke of the driver. Also operating in. the column in conjunction with the driver 33 isa; plunger 35 reciprocally slidable in a cylinder 36. .Ihe upper ends. of the driver 33 and the plunger 35. are cqmpanionably screwed into a rounded knob 31, and the distance they are screwed into this knob will. control or. adjust the length of the stroke of the driver and similarly the distance the, nails are countersunk. In the cylinder "itv beneath; the plunger is a spiral spring 31a expanding agait a collar38; on the plunger and the upper face of the base, and; compressing. on the down. stroke of the plunger andv driver and thereby urging the lattenmembers' to: upper dead-centre in preparation tor a. subsequent stroke.- againstthenail of. the, train-following the one having been driven.
Thus the nails. are driven, and countersunk in their consecutive order in; the .trainby placing the opening; 31; in registry with. thezpointatwhich the nail is tobe, drivenandstriking theknob 31 bythe palmof. the; hand, the clenched fist, or an in. the; form and construction, ofv the-inventionwithout. departing from; the material spirit theretoreceivereplacement trains for impelled movement into the feed passage progressively as the nails in the feed passage are singly ejected, of a magazine associated with said base for containv ing a disarranged mass of nails having communication with theannular passage, a shaft centrally arranged in the magazine for turning andslid- I ment with the traini-in. the annular passage and adapted to be. depressed out of train engagement ing movement therein, a pusher arm fixed to one enclofthe shaft in spring pushing engagement with the 'trains in the annular passage' and adapted tobe moved in and out of train engage ment position and -tobe'swungon the. axisof the shaft with the shaft, and spring. means associated with the shaft andpusher'arm forurging'ithe pusher arm against the train. n m
