Abstract
Abstract This invention relates to a storable hoisting gin or boom member attachment for bucket loaders which provides an arrangement for quickly and easily moving a boom member or gin pole into working relationship with respect to a bucket loader so that this type of construction vehicle may be used for lifting and lowering objeccts in construction work. The attachment consists of supports welded to the top side of the bucket, each support including a pivot flange and a retaining flange to which the boom or gin is attached. Each pivot flange permits pivoting of the boom member to a collapsed position on an opposite support on the top side of the bucket for storage purposes.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
248 words
A hoisting gin comprising: (a) a front-end loader having a pivotally mounted bucket extending transversely thereof at its forward end; (b) said bucket having end and upper and lower side walls; (c) a pair of oppositely disposed anchor members mounted upon an upper surface of said upper side wall of said bucket in laterally spaced relation adjacent opposite ends of said bucket and each constructed and arranged to pivotally anchor a gin pole upon said bucket; (d) a longitudinally telescopic gin pole constructed and arranged to have its inner end received within one of said anchor members in pivoted anchored relation for pivotal movement about a substantially vertical axis between an anchored forwardly extending working position and a transverse stored position adjacent the other of said anchor members; (e) a pole-locking member mounted on said upper surface of said upper side of said bucket forwardly of one of said anchor members and constructed and arranged to engage and releasably lock said gin pole in extended working position when said gin pole is pivoted to forwardly extending position relative to said bucket and said anchor members; and, (f) said gin pole being telescopic to a length approximating the distance between said pair of anchor members and having its outer end constructed and arranged to be engaged and secured by said other anchor member when said gin pole is so telescoped and pivoted to its stored position whereat it extends transversely of said loader and longitudinally of its said bucket.
Claim 2
Dependent Claim
248 words
A hoisting gin comprising: (a) a front-end loader having a pivotally mounted bucket extending transversely thereof at its forward end; (b) said bucket having end and upper and lower side walls; (c) a pair of oppositely disposed anchor members mounted upon an upper surface of said upper side wall of said bucket in laterally spaced relation adjacent opposite ends of said bucket and each constructed and arranged to pivotally anchor a gin pole upon said bucket; (d) a longitudinally telescopic gin pole constructed and arranged to have its inner end received within one of said anchor members in pivoted anchored relation for pivotal movement about a substantially vertical axis between an anchored forwardly extending working position and a transverse stored position adjacent the other of said anchor members; (e) a pole-locking member mounted on said upper surface of said upper side of said bucket forwardly of one of said anchor members and constructed and arranged to engage and releasably lock said gin pole in extended working position when said gin pole is pivoted to forwardly extending position relative to said bucket and said anchor members; and, (f) said gin pole being telescopic to a length approximating the distance between said pair of anchor members and having its outer end constructed and arranged to be engaged and secured by said other anchor member when said gin pole is so telescoped and pivoted to its stored position whereat it extends transversely of said loader and longitudinally of its said bucket.
Claim 3
Dependent Claim
206 words
A storable boom for use with a construction machine having a scoop type bucket mounted on one end of the machine through linkages for elevating and pivoting the bucket about an axis extending transverse of the machine, the bucket having upper and lower sides with connecting end walls and with the lower side being adapted to be disposed on the ground when the bucket is pivoted forward, comprising: a boom member, a support adapted to be mounted on the upper side of the bucket adjacent one end thereof, said support including a pivot flange and retaining flange with the pivot flange positioned rearwardly of the retaining flange and releasably mounting one end of the boom when so mounted upon the bucket and with the retaining flange selectively retaining the boom against pivotal movement, said boom member having a length and being mounted in said support to extend beyond the bucket when in use and being pivoted on the support into alignment with the upper side of the bucket when stored; and means adapted to be positioned on the upper side of the bucket adjacent the opposite end thereof for retaining the other end of the boom member on the upper side of the bucket when stored.
Claim 4
Dependent Claim
206 words
A storable boom for use with a construction machine having a scoop type bucket mounted on one end of the machine through linkages for elevating and pivoting the bucket about an axis extending transverse of the machine, the bucket having upper and lower sides with connecting end walls and with the lower side being adapted to be disposed on the ground when the bucket is pivoted forward, comprising: a boom member, a support adapted to be mounted on the upper side of the bucket adjacent one end thereof, said support including a pivot flange and retaining flange with the pivot flange positioned rearwardly of the retaining flange and releasably mounting one end of the boom when so mounted upon the bucket and with the retaining flange selectively retaining the boom against pivotal movement, said boom member having a length and being mounted in said support to extend beyond the bucket when in use and being pivoted on the support into alignment with the upper side of the bucket when stored; and means adapted to be positioned on the upper side of the bucket adjacent the opposite end thereof for retaining the other end of the boom member on the upper side of the bucket when stored.
Claim 5
Dependent Claim
42 words
The storable boom of claim 2 in which the means positioned on the upper side of the bucket is a second support including a pivot flange and retaining flange, said boom member being selectively mountable in either the first or second support.
Claim 6
Dependent Claim
34 words
The storable boom of claim 2 in which the boom member is formed of telescopic parts adapted to extend and including means for selectively holding said boom member in an extended or retracted position.
Claim 7
Dependent Claim
42 words
The storable boom of claim 2 in which said pivot flange is a flange member having a removable pin positioned therethrough and in which the end of said boom member mounted therein has an aperture therein through which the pin is positioned.
Claim 8
Dependent Claim
18 words
The storable boom of claim 5 in which said pivot flange includes means for retaining said pin therein.
Claim 9
Dependent Claim
35 words
The storable boom of claim 5 in which said retaining flange is a right angle bracket member with a removable pin positioned therethrough to extend vertically along the side of and hold said boom member.

The boom support of claim 3 and including an intermediate U-shaped support member adapted to be mounted on the upper side of the bucket intermediate the first and second supports and adapted to support a portion of said boom member in the stored position.
Claim 11
Dependent Claim
45 words
The boom support of claim 3 and including swivel means mounted on the outer end of said boom member with a cable having a lifting hook at the end of the same for connecting the cable to loads to be supported by said boom member.
Claim 12
Dependent Claim
73 words
The boom support of claim 2 and including coupling means mounted on the outer end of said boom member and adapted to couple said boom member to a load, said coupling means also being adapted to couple to said means positioned on the upper side of the bucket adjacent the opposite end thereof to retain the other end of said boom member on the upper edge of said bucket in the stored position.
Claim 13
Dependent Claim
29 words
The boom support of claim 9 and including loop means mounted intermediate the extent of said boom member and adapted to receive the lifting hook in the stored position.
