2C1aims.
This invention relates to a tool device for applying fasteners, particularly screws, and specifically is concerned with an improvement in tools for driving such fastening members in locations which are already marked on the work, as by depressions or sockets. I
The invention will be described principally as adapted for applying screws for holding perforated acoustical tile to a suitable backing, for instance, as illustrated in my prior application, Serial No. 203,046, filed April 20, 1938, now
Patent No. 2,160,794 in which are shown, but not Another object is to provide a simple means for aligning a fastener with the axis of a tool part such as a screw driver-or nail set so that the point of the fastener willremain centered on such tool axis during starting of the driving operation on the fastener.
A further object is to provide a simple device for locating a, fastener-driving tool and the fastener with reference to a depression or socket, or a particular work.
Other objects and features of the invention will become apparent from the following description relating to the accompanying drawing showing the preferred forms. The essential characteristics-are summarized in the claims.
Referring to the drawing, Fig. 1 is a fragmentary plan view of a comer portion of a perfbrated acoustical tile, said view showing, in transverse section, an end portion of the tool device hereof in fastener-locating position. Fig. 21s a central longitudinal sectional view of the tool showing a further modified construction, particularly of a fastener-centering means, and of a tool device locating means. Fig. 5 is a transverse one of a pluralitythereof, in the sectional view taken substantially along the line 55 on Fig. 4. A
Referring to Fig. 1, the tile T, a corner portion of which is shown, may be formed, for instance, of matted fibers as in the well known Acousti- Celotex tile. Such tile has a multiplicity of sound receiving perforations p distributed overits exposed face, including a small group such as specifically indicated at a, b, c, and d close to the corner and which are shallower than the others. The relationship in depth of the perforations is illustrated in Fig. 2. v
The tool \device, as shown in Figs. 1 to 3, comprises a body member I adapted conveniently to be held in the hand; the body being provided centrally of it with a fastener-driving part 2 (here: inafter referred to for convenience as the tool) which may have a screw driver end 3 for engagement with an ordinary wood screw such as indicated at S, or a, helical nail (drive screw) which is to be driven through the tile and into a suitablebackingfor the tile such as indicated in Fig. 3 at B. The body may be non-circular for facilitating gripping of it in the hand, or knurled as suggested at 5.
At the outer end of the body are a pair of arms 6 which support tool-locating 'pins I and 8 parallel to the axis of the tool. One can be, shorter than the other (pin 1) and adapted to engage any one of the perforations a, b or c, and the other (pin 8) one of the perforations p, as in Fig. 2, to locate the axis of the tool directly over one of the shallow perforations b, c, or d.
becomes properly. aligned with one of the shallow perforations. Two 'of the four proper positions of the arms 6 are indicated, one by broken lines. Wider spacing of the pins from the tool axis could be used to align the tool with the perforation it only, if desired.
The tool 2 is supported slidably and rotatably in the body I as by easy fit in a bore III at one end of the body and similar fitting of a shank portion l2 in a central bore 15 of a cap piece I6. The cap piece may be threaded onto the body as at IT. Located in a counter-bore 20 of the body is a coil spring 2| surrounding the shank of the tool and bearing at oneend on-the cap piece l6 and at the other against an enlarged abutment element or shoulder 22 fastened to the tool 2 against axial movement thereon. The spring normally forces the tool end 3 towardthe bore I0 in a direction tending to drive the fastener into the work. The outer end of the shank I2 is suitably formed as at 23 for engagement with a driving member or mechanism such, for instance, as the chuck of the well known Yankee type screw driver. shoulder 25 are adapted to cooperate with such chuck. The specific nature of the shank end is unimportant, since any type of driving means can be used to operate the tool 2. In the form shown, compression of the spring limits the outward or retracting movement of the tool in the body I.
From the above, it will be seen that with the tool 2 withdrawn to. the position shown in Fig. 2, the fastener, such as a screw S may be dropped in the outer end of the bore l0 and then, upon rotation of the tool 2 and advancement of it toward the bore I0, the end 3 will become engaged with the slot in the head of the screw to enable the screw to be turned and forced endwise to drive the screw into the work. When the screw has advanced so that its head is seated in the bottom of the perforation b as shown in Fig. 3, then the abutment element 22 engages the inner end 21 of the counter-bore 20 and prevents further driving of the screw, thus limitin the fastening force of it. This same limiting will occur on the remaining three .Jrners of the tile so that all four corners are attached with the same force. The
actual location of the limiting stop depends upon the position at which the screw head is to beseated in or against the work. The stop can be made adjustable in any appropriate manner (not shown). A threaded collar on the outer end of the shank l2 adjacent the formation 23 could serve as an adjustable stop by engagement with the cap I6. 7
Preferably, the abutment element 22 comprises an anti-friction thrust bearing, such for instance, as shown in Fig. 3, wherein a series of balls 30 are retained in races of bearing ring members 3| and 32 which are held in position on the tool 2 as by engagement of one of the bearing members with a shoulder 34, and of the other with a collar 35 fastened as by an appropriate pin to the tool' 2. Suflicient clearance is provided between the plane of the shoulder 34 and the near end of the collar 35 adjacent the bearing ring 3lso that the bearing can always turn freely. With such anti-friction bearing limitin the outward movement of the tool 2, there will be no wear on the abutment stop, such as 21, provided to limit the advancement of the tool end, and no appreciable resistance to free rotation at any time.
It will be apparent that a device constructed as described could be used to drive any sort of nail and limit the fastening force thereof. The end portion of the tool would ordinaril be modified in accordance with the fastener-with which to be used.
Figs. 4 and 5 illustrate, particularly, an arrangement for centralizing the fasteners, as when the heads thereof are large in proportion to the shanks, or whenever required by the nature of the work. As shown,a modified locating member 40 The detent notches 24 and driving is shown on the end of the body id for engagement with a socket or depression 4| in the mem her to be fastened, which socket receives the head of the fastener in the final position of it. The member 40 may comprise a conical extension of a sleeve 42 secured to the head as by threads 43.
Radially positioned bores 45 spaced about the axis of the tool may support spring-pressed centering members for the fastener S, such as steel balls 41 arranged relative to the fastenerreceivlng bore M as shown in Fig. 5. The balls can be limited in their inward movement as by constricted portions of the radial bores as at 48. Suitable yielding means for moving the centering elements 41 into operating position may comprise a single coil spring 49 in a circular recess 50 intercepting the bores 45 in the plane of the centers of the balls 41; the ends of the coil spring being detachably secured together as at 5|.
It will be apparent that when placing the fastener in the tool device, the head of the fastener pushes the balls 41 outwardly, and that when the fastener is then moved or dropped into engagement with the working end of the tool .2, the shank will be held centered; and also that, as the tool is advanced, the head of the screw again pushes the balls back out of the way of the head to allow the latter to pass out of the bore toward the work.
I'claim:
1. A device for driving a headed fastener into one of a number of prearranged spaced sockets in the work, said device comprising a body adapted to be grasped by and supported in one hand of an operator, said body having a tool slidably arranged in it, a bore in the body adapted to receive an elongated fastener substantially entirely therewithin and to guide the head into cooperative engagement with one end of the tool, and short pins on the body parallel to the tool axis and diminishing in cross section toward their extremities, said pins being arranged for selective engagement with a plurality of said sockets in the work in a manner to align the tool with another one of such sockets.
2. A device of the class described comprising a body adapted to be held in the hand and having a tool slidably arranged in it, said body having a surface of considerable extent adapted to abut the work, said surface extending in a direction substantially perpendicular to the axis of the tool, and means projecting beyond said surface to engage the work in a manner to locate the tool in proper position relativeto the work, a bore in the body adapted to receive a fastener for cooperative engagement with one end of the tool, and
abutment means on the body and tool to limit the forward movement of the tool relative to the body, whereby, when said surface is held in abutment with the work at each position at which fastening is desired, each fastener will penetrate MANLEY R. PRICE.
