6 Claims.

This invention relates to a device for securing a wire member in the end of a wooden handle and more particularly to a machine for manufacturing package carriers comprising a handle member having cord engaging hooks secured thereto.

As is well known in the art there are many types of package carriers some of which comprise a hollow wooden handle member with a wire passing through the centre thereof and having cord engaging hooks formed on each end. Other types have the cord engaging members secured to the handles by means of fasteners of various types.

It is therefore the purpose of this invention to provide a machine for manufacturing a package carrier handle comprising a cylindrical grip member, of any suitable material, such as wood, having cord engaging hooks driven into the ends thereof and having the wood or other material.

sealed about the cord hooks.

The machine is adapted to drive a cord hook of wire or other suitable material into the end of a solid grip member of wood or other material, such as a dowel which has been cut to a predetermined length. The dowels are fed onto a V block and the hook members are preformed and placed on a guide which is a part of a driving and folding tool. The driving tool is retractable with rela- 7 tion to the folding tool. Both are driven forward by any suitable means until the hook member has been drivena predetermined distance into the end of the dowel, at which time the driving tool is retracted and the folding tool continues to move forward cutting a shallow slot in the end of the dowel and folding the wood about the hook member thereby sealing the wire into the wood and forming a substantially unitary structure.

It is therefore the principal object of this invention to provide a machine for assembling and forming a novel form of package carrier.

A further object is to provide a machine which is adapted to seal the cord engaging hooks of a package carrier handle into the grip portion thereof thereby forming a substantially unitary struc- Fig. is a cross'section thru 5.5 of Fig. 4, 5

Fig. 6 is a cross section thru 6-6 of Fig. 4,

Fig. 7 is a cross section thru 'l! of Fig. 4 and Fig. 8 is a view in perspective of a finished package carrier.

As disclosed in Figs. 1, 2 and 3 the machine em- 10 bodying the invention comprises a bed plate I supported by any suitable means such as framework 2. Mounted on the bed plate I is a hopper and chute 3 from which the dowels 4 are fed tola V block 5 centrally located on the bed plate. .Situated in line with and on each side of the V block are the driving and sealing tools 6 which are adapted to be moved intoand out of engagement with dowel 4, positioned on V block 5, by means of arms L'bell crank levers 8, and link members 9, which are in turn operated by draw bar l0 pivotally connected to a foot pedalv I I. It is obvious that other means such as a motor operated cam and lever may be used in place of the bell crank and foot pedal. The tool 6 is positioned in a gib or guideway l2 cut in the bed plate and is connected to arm I by a right and left handed adjustment screw l3 byimeans of which the distance travelled by the tool 6 may be varied in accordance with the length of dowel arm I has a. stub shaft l4 projecting from each side thereof which is adapted to cooperate with a fork formed in the end of hell crank 8. The bell crank is pivoted on a pin l5 carried in a boss l6 formed on the framework 2. The links 9 are pivotally connected together by pin l1 and to bell cranks 8 by pins l8. The pin II also connects the links 9 to a hanger l9 formed as shown. The hanger is in turn connected to draw bar I0 by means of pin 20. A tension spring 44 connects hanger l9 to the under side of base I. A pin 2| pivotally secures bar I ll to the foot pedal H which is in turn pivotally mounted on shaft 22 carried by frame 2.

The V block 5 is positioned in a slot 23 cut in 45 the bed plate and is vertically adjustable thereto by means of adjustment screws 24 thus permitting the V block to be raised or lowered thereby centering a dowel carried thereon directly opposite the driving tool regardless of the diameter of the dowel.

The tools 6 are identical in structure so therefore a description of one will clearly define their construction and operation. The main body or base 25 of the tool is formed as shown in Figs.

used. The

drawn from the' notch- 32. .screws42 may be so positioned that the pawl is 33 strikes the boss then actuates the foot pedal 2 4 and 7, having a tenon formed on the bottom thereof cooperating with guideway |2. The rear portion of the base is formed as shown having a hole tapped therein to accommodate an adjustment screw l3. Four bosses 26 are formed on the base which are tapped to accommodate screws 21 which are used to secure a cover plate 28 in place. The bosses 26 are slightly taller than the thickness of the driving plate 29 which is positioned therebetween. This allowance is made to permit free movement of the driving tool or plate. Pivotally mounted on base 25 are two pawl members 39 which are formed as shown in Fig. 4. The pawls have L shaped arms 3| formed integral therewith as disclosed in Fig. 5. The driving tool 29 is a flat plate having an arcuate notch cut in the front face. thereof, as shown in;

Fig. '7, which is adapted to hold the wire hook member while being driven into the dowel. The driving plate has a notch 32 cut in each side adapted to cooperate with the pawl 30. The looking action of the pawls and notches causes the driving plate to be carried forward by. the base or folding tool 25. The driving plate also has an arm 33 formed on each sidethereof as shown in Figs. 4 and 6. Base 25 also has an arm 34 formed on each side near the end. A tension spring 35 connects arms 33 and 34 and a compression spring 36 is positioned between arms 3| and 33. The function of these springs will be hereinafter described. The front edges of base 25 and cover plate 28 are provided with cutting edges 31 as shown in Fig. '7 thereby forming the cutting and folding tool. The base 25 has a. plate 38 formed integral therewith which is provided with a pair of pins 39 and acts as a carrier and guide for the wire hook member 40.

Formed on or secured to the bed plate I in any well known manner are a pair of lugs 4| which are tapped to accommodate an adjustment screw 42 which is in turn adapted to engage the arm 3| on the pawl 30 and cause the pawl to be with- These adjustment withdrawn at a certain predetermined point in the stroke of the machine. Two additional lugs 43 are formed on bed plate I and are so positioned that they cooperate with arms 33 and are used to reset the pawls 30 after a complete stroke of the machine has been finished. When the pawl is withdrawn from the notch 32 by the action of arm 3| against the screw 42 the tension spring 35 retracts the driving tool until the arm 26. The driving plate remains in this position until on the return stroke the arm 33 strikes the lug 43 thereby holding the driving plate stationary and the folding and cutting tool is drawn back until the pawl 3|] again engages the notch 32.

In operation the machine completes a cycle in the following manner: a dowel 4 is fed to the V block by gravity and the pre-formed wire hook 40 is positioned on the pins 39. The operator thereby drawing links 9 down against the tension of spring 44 thus forcing the bell crank levers 8 outwardly. The bell crank levers pivoting on pins I5 move the tools 6 toward the dowel through the action of the fork on pins l4 and the medium of arms 1 and adjustment screws IS. The tools 6-with the plates 38 carry the wires 40 forward and they are forced into the end of the dowel by the driving tools 29 until a predetermined point is reached at which time the arms 3| come in contact with 4 adjustment screws 42 thereby tripping the pawls ufacture of carrier aoiasea 30 and permitting the driving plate to be with drawn as shown in Fig. '7. The cutting edges 31 now out a small slot in the end of the dowel tools 6 are withdrawn until the arms 33 come into contact with the lugs 43 thereby holding the plate 10 29 until the pawls 33 again engage the notches 32. In the meantime the operator has removed the finished carrier handle thereby allowing another dowel to fall onto the V block. Another set of wire hooks is then positioned on the pins 15 39 and the machine is ready for another cycle.

It -is obvious from the above description the uses of this machine are not limited to the manhandles but may be successfully used in the manufacture of any article go in which a wire member is driven into a wooden block and sealed therein such as certain forms of brushes and light tools.
