Description
BOWLING PIN RECONDITIONING APPARATUS
BACKGROUND OF THE INVENTION
This invention relates to apparatuses for reconditioning bowling pins, particularly apparatuses for removing and replacing rings extending about the bodies of bowling pins.
One type of bowling pin commonly in use includes a rigid body having a resilient ring extending releasably about the lower portion thereof. These rings become damaged and worn with use and eventually have to be replaced. It can be a laborious task to pry the rings off of the pins and then force new ones back in their place. This has been conventionally done by pounding the rings off and on with a mallet. This operation is not only time consuming, but can result in damage to the new ring or to the body of the pin itself.
Accordingly it is an object of the invention to provide an improved apparatus for removing and replacing rings on bowling pins.
It is also an object of the invention to provide an improved apparatus of the type which is simple and rugged in construction.
It is further object of the invention to provide an improved apparatus of the type which makes the job of replacing rings much faster and more convenient than prior art apparatuses and methods.
SUMMARY OF THE INVENTION
According to the invention there is provided a reconditioning apparatus for a bowling pin having a pin body and a ring removably connected thereto. The apparatus includes a stand and an upright member having a top and a bottom connected to the stand. There is a lever 30 pivotably connected to the top of the upright member. An elongated member has a top pivotally connected to the lever a distance from the upright member and a bottom. There is a ring removal tool connected to the bottom of the elongated member.
Preferably the app~alus also includes a pin top receptacle connected to the lever. There may be a ring support on the stand aligned with the receptacle. The ring support has a space sufficiently large to accommodate downward displacement of the pin body relative to the ring and the ring support.
The invention offers significant advantages over prior art apparatuses and methods for removing and replacing bowling pin rings. The operation can be carried out efficiently and neatly without much physical effort and without potential damage to the bowling pin body or the new ring. A single tool can be used for both operations, namely removing the old ring and installing a new one. In a pl~relled example, the invention also provides a convenient way of removing base caps from pin bodies as well.
BRIEF DESCRIPTION OF THE DRAWINGS
Fig. 1 is a side elevation, partly broken away, of a reconditioning appal~lus for bowling pins according to an embodiment of the invention, a bowling pin being shown in stippled lines in the position for removal of the ring;
Fig. 2 is an end view thereof with a bowling pin and the pin top receptacle shown in stippled lines in the position for installation of a ring on the bowling pm; and Fig. 3 is a top plan thereof.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to the drawings, these show an apparatus 10 for reconditioning bowling pins, such as pin 12 shown in Fig. 1 and 2 in stippled lines. The apparatus includes a base 14 which in this example is a generally rectangular flat metal member having a plurality of rubber foot pads 15 mounted on the bottom thereof.
There is an upright member 18 which in this example includes an upper portion 20 made of square metal tubing although other rigid, elongated members can be substituted. There is a bottom portion 22 which, in this example, is a shorter length of square tubing larger in section and fixedly connected to the base 14. Upper portion 20 is received in the bottom portion when the apparatus is assembled.
The upper portion 20 of the member 18 has a top 24. There is a lever 26 pivotally connected to the top of the member 18 by means of a pivot pin 29. In this particular example the lever has three sections 28, 30 and 32. Section 28 includes a pair of spaced-apart straps 34 and 36 connected together by a member 38 of similar section as shown best in Fig. 3. A handle bracket 40 is rigidly connected to the member 38 by welding or the like. The bracket in this example is a tubular member having an inside diameter slightly greater than 1". Section 32 of the lever fits inside the handle bracket and has a h~ndgrip 42 at the distal end thereof.
The ~pal~lus according to the preferred embodiment has an optional cap remover 50 shown in Fig. 1 and 2. The cap remover includes a U-shaped blade 52, shown best in Fig. 1, having a relatively sharp inner edge. The blade 52 is mounted on the member 18 by means of a pair of spaced-apart bolts 54 and is spaced-apart outwardly from the member as best shown in Fig. 2. Many bowling pins have removable caps on the bottoms thereof which are removed in order to replace ropes conventionally used to connect the bowling pin to a pin setting machine.
In this embodiment the lever 26 is resiliently biased towards a raised position by a coil spring 60 connected to a tab 62 connected to end 64 of the lever 26 which extends on the opposite side of member 18 from the handgrip 42. The coil spring has a lower end connected to one of the bolts 54.
There is a ring remover 70 which in this embodiment is a U-shaped curved member having two prongs 72 and 74 shown best in Fig. 2. The ring remover is connected to bottom 76 of an elongated member 78 shown best in Fig. 1. Top 80 of the member 78 is pivotally connected to the lever 26 a distance from member 18. There is a ring support 84 which, in this example, is in the form of a tubular member having a diameter slightly less than the outside diameter of ring 86 of bowling pin 88 shown in Fig. 1.
There is a thin, elongated member 90 extending perpendicularly upwards from base 14 along the center of the ring support. The member is connected to the base by a head 92. The member 90 is of a size slightly smaller in diameter than an aperture at the bottom of the bowling pin 88 to slidably fit therein.
There is a removable platform 94 pivotally connected to the ring remover by a bolt 96.
There is a curved slot 98 in the platform, shown best in Fig. 3, to clear the member 90 when the platform is swung over the ring remover. In that position, the platform supports pin 88 in the position shown in Fig. 1 so the bottom of the pin is on top of the platform. The ring remover 70 is then placed on top of ring 86 as shown in Fig. 1. Lever 26 is pressed downwardly by means of handgrip 42 to push the ring off an annular groove 100 of the bowling pin. Thus a worn or damaged ring can be removed from the pin.
The apparatus is also capable of in~t~lling a new ring ~ltili7.ing a pin top receptacle 102 which is cup-shaped so as to fit on the top of the bowling pin. In order to install the ring, platform 94 is swung out of position as shown in Fig. 1. This allows the pin 88 to drop into space 104 within the ring support 84 as shown in Fig. 2. The ring 86 is then supported by the top of the ring support. The pin top receptacle 102 is then placed over the top of the pin as shown in broken lines in Fig. 2. Lever 26 is then pressed downwardly which forces the bottom of the pin through the ring 86 until the ring is in the proper position over groove 100. When a ring is being installed the receptacle is swung away from the top of the pin as shown in stippled lines in Fig. 1.
Variations and Alternatives It will be understood by someone skilled in the art that many of the features described above are by way of example only and can be altered or deleted without departing from the scope of the invention which is to be hlt~ led with reference to the following claims.
For example, the platform 94 can be replaced with a spool-like member which fits over the thin, elongated member 90. The spool can be made, for example, of two washer-like members connected by a section of tube.
The member 90 can be replaced with another such member having a different diameter for pins having dirrelelll size apertures on the bottoms thereof. Alternatively sleeves may be placed over the member 90 to accommodate pins having larger holes.
