Description
~C~5~9 The invention refers par-ticularly to a tip member ~or at-tachment to the front end portion of a powder actua-ted fastener and for engagement in an angle bracket, clamp, clip or other member (hereinafter referred to as "bracket") which is to be fastened to a support member by means of the fastener.
It has been proposed to provide an assembly of a brac-ket with an aperture therein; a collar member engaged in -the aperture and having a tubular sleeve to receive -the fastener and a flange at one end to prevent the collar passing through the aperture in one direction; and a guide sleeve on the fastener to ensure correct location and move-ment in the barrel of an explosive powered tool.
Thls construction has several disadvantages and this invention has been devised with the object of providing an improved construction of a member for attachment to the ~
front end of a power actuated fastener and for engagement in the aperture of a bracket. This invention provides a simplified assembly of bracket, fastener and guide means.
The invention also provides a construction of a tip member for attachment to the front end of a fastener and engage-ment with a bracket to be secured in position on a support member wherein the fastener and tip member may be used to-gether in the barrel of a fastener tool.
According to one aspect of the invention there i~ pro-vided a tip member, for engagement on the front end portion `
of a powder actuated fastener, having a body portion, `
the front end.
.
- 1 - ~ : .' ~5~6~39 part of the body being of a shape and si~e to fit tightly in an opening in a bracket which is to be secured to a support member. A deflectable peripheral enlargement on the longitudinal surface of the body portion of the tip member is disposed rearwardly of the front end par-t and has an external variable dimension which permits the tip member to fit slidably in the barrel of an explosive powered tool. The peripheral enlargement is shaped to fit readily into and to slide smoothly in said barrel whilst holding the fastener in position and yet permits the passage of gaseous products of combustion The tip member `
also includes a bore through the body portion of a dimen- ;~
sion at its rear end -to receive tightly the front end por-tion of a fastener.
In another aspect, the invention provides an assembly of: a bracket having a fixing plate portion with an aper-ture therein,; a tip member engaged firmly in the aperture and a fastener of the type described engaged in . . .
the tip member. The tip member has a front end part to engage tightly in the aperture of the bracket and rearwardly of that front end part a guide portion to fit in -the bar-rel of a powder actua-ted tool and assist in holding -the fastener in correct position and in guiding it in its travel in the barrel. If th~bracket is to be attached to a flat surface the fixing plate is flat but, of course, it is to be attached. For convenience of manufacture ;
:;' ': ' . ' `' ' ~ ' " ' ~0~6'39 the aperture in the bracket is preferably round, and the front end part of the tip member may be of any suitable shape to fit securely -therein.
The bracket may, of course, be an angle bracket, or shaped to clamp cables in position, or of any other de-sired shape and type.
The aligning tip has a front end part which provide~
a tight fit in the aperture in the bracket so that when the aligning tip is assembled to the bracke-t parts will not separate in normal handling. ~-The bore of the aligning tip may be parallel-sided at the front end for a distance about the same as the enlarged front end part and this portion of the bore is smaller than the remainder. For example, it may be about one-half the diameter of the rear end, or a little smaller or larger, as required. The rear end part of the bore is also parallel-sided and the intermediate part is curved in longitudinal section, or of truncated conical shape, or stepped as re~uired. The rear portion of the bore provides a tight fit on the front end part of a fastener whereby the parts .
may be assembled and will not separate during normal hand-ling.
In normal assembly the fastener is pressed in-to the tip until the front end part of the fastener engages the inner end part of the smaller front end of the bore. The front end of the tip member is then pressed into the brack-et aperture and is re-tained therein by friction or in-ter~
ference fit. The ~5~L6~
assembly is the~ complete and may be handled in a normal manner without coming apart.
The connecting tip member is preferably made of a material which will shatter or disintegrate when the fastener is driven through it. Polypropolene has been found satisfactory for this purpose. Other plastics materials would also be suitable, as may be other materials.
It is, therefore, an object of this invention to provide a consumable connector for temporarily but firmly interconnecting an elongated nail-like fastener with a bracket which is to be secured to a supporting surface by the fastener.
It is a further object of the invention to provide a connector of the character described which is made of a material which breaks up when the fastener is driven into the supporting surface so as not to interfere with the fastener's ability to secure the bracket to the supporting surface.
It is yet another object of this invention to provide a connector of the character described which may include a variable guide portion to center and guide the fastener in the barrel of a power actuated fastening tool.
It is still a further object of this invention to pro-vide a fastening assembly including a fastener, a bracket, and a connector of the character described.
In accordance with an embodiment, there is provided a disintegrating connector member for use in providing a temporary connection between an elongated fastener shank and a bracket having at least one aperture therethrough, said member comprising:
an axially elongated body formed from an elastically deformable material, said body having a forward nose portion sized to engage the bracket aperture for retention of the bracket on the connector member, a bore extending axially of the body sized to snugly receive and retain the fastener shank therein, and a rearward part ~LCl S~69~
of said body being formed with a plurality of radially outwardly and rearwardly extending wings which are radially deflectable to provide means for snugly engaging a plurality of different diameter bores, said wings being joined to said body along a cir-cumferential hinge line to facilitate said radial deflection, each of said wings being separated from the adjacent wings by intervening substantially V-shaped slots.

The function of the wings 14 will be de-tailed hereinafter.
The internal construction of the connec-tor 2 is shown in FIGURE 3. It will be noted that there is an axial through bore 20 formed in the member 2. The bore 20 pre-ferably includes a forward cylindrical portion 22 of reduced diameter, and a remaining portion 24 of tapering diameter which expands in the rearward direction.

The bracke-t 26 in-cludes a pair of angularly offset legs 28 and 30, each of which is provided with a through aperture 32 and 34 respec-tively. This bracket is commonly called an angle bracket however, it will be readily understood that the connector
2 could be used with any number of common types of brac-kets, such as pipe brackets, hanger brackets, electrical wiring brackets, or the like.
The fastener assembly is put together by inserting the pointed end of an elongated nail-like fastener 36 into the tapered bore 24 of the connector 2 -to tightly unite the connector 2 and fas-tener 36. The point of the fast-ener 36 will be located in the cylindrical bore 22 but will not usually `~

protrude from the forward end of -the connector. The nose 4 of the connector 2 is -then pushed through -the appropriat-ely sized bracket aperture 32 or 34 until the rib 8 is contained within or has passed through the bracket aperture.
The taper 10 makes easier insertion of the connector nose 4 into the bracket aperture. It will be understood that the natural resiliency of the connector material will serve to frictionally hold the rib 8 in the bracket aperture or will enable the rib 8 to pass completely through the brac-ket aperture, at which time the rib 8 will rebound to hold the connector 2 and bracket 26 tightly together.
Referring to FIGURE 5, the manner in which the fastener assembly is aligned in a pwer actuated tool prior to being set in a supporting material M. The barrel of the tool is designated by the numeral 46 and its bore is 38. The tool shown is a piston tool and the piston is numeral 40. The fastener 36 has its shank 42 telescoped into the conne~tor bore 24 and has a rearward head 44 which is somewhat smaller than the diameterof the barrel bore 38. The fastener head ~;
44 provides a striking surface for the piston 40 and serves to center and guide the rear end of the fastener assembly in the barrel bore 38. The tail portion 12 of the connec-tor 2 is positioned within the barrel bore 38 7 and the bar-rel bore diameter is such that the wings 14 are inwardly de~lected when they engage the barrel bore 38. The inher-ent resiliency of the connector wings 14 causes them -to be biased outwardly against the barrel bore 38 to center -;9~
and guide -the front end of the fastener assembly in the barrel bore. It will be appreciated -that the provision of deflectable wings 14 on the tail portion 12 of the connector member 2 provides some versatility to -the con-nector member in that it can be used to center and guide a fastener assembly in a number of diff`eren-t size barrel bore diameters. It will also be appreciated that the tail portion 12 can be eliminated altogether and the body por- -~
tion 6 diameter can be custom sized to mate with any known barrel bore diameter. A slightly less versatile connector is formed in that manner.
It will be readily appreciated that this invention pro-vides an expendable connector useful for producing fastener assemblies, wherein the connector is shattered or des-troyed when the fastener assembly is driven into a supporting material. The fastener assembly has provision for centering the fastener while in the -tool barrel bore, and, in a pre-ferred embodiment, can be used with a variety of bore dia-meters. The connector is inexpensive to manufacture and can be molded from suitable plastic material.
Since many changes and variations of the disclosed -embodiment of the invention may be made without departing from the inventive concept, it is not intended to limit the invention otherwise than as required by the appended claims.
