Smith - Web page: https://patentgrep.com/patent/US10480152B1 ## CPC - E02F 3/3681: {Rotators} - E02F 3/3686: {using adapters, i.e. additional element to mount between the coupler and the tool} - E02F: DREDGING; SOIL-SHIFTING (winning peat E21C49/00) ## Abstract A swivelable adapter device for use with skid steer loaders consists of a mounting plate and a swiveling work tool plate for holding, rotating, and positioning various skid steer attachments. Rotation about a longitudinal axis of skid steer arms is accomplished using a barrel within a barrel assembly allowing work tool plate to be positioned from angles between horizontal and vertical. A mounting plate is attached to skid steer arms and is rigidly affixed to an inner barrel. An outer barrel with a notch plate and a work tool plate slides over a greased inner barrel. Swivel operation of the work tool plate is accomplished by hand eliminating the need for hydraulic systems. Once positioned, the work tool plate is locked to a notch plate using a locking latch. The swivelable adapter device is reinforced with metal plates to handle torsion forces created by heavy loads such as trees. ## Claims ### Claim 1 A swivelable adapter device for a skid steer loader comprising: a mounting plate; a forward reinforcing mounting plate; an aft reinforcing mounting plate affixed to an inner barrel, the aft reinforcing plate contacting the mounting plate, the forward reinforcing mounting plate contacting the mounting plate, the mounting plate being positioned between the forward reinforcing mounting plate and the aft reinforcing mounting plate; a work tool plate affixed to an outer barrel; and a notch plate contacting the forward reinforcing plate and coupled to the outer barrel, the notch plate engaging a locking latch, wherein an outer barrel inside dimension is greater than an inner barrel outside dimension to allow clearance for said outer barrel to slide over said inner barrel, wherein said work tool plate is affixed to said outer barrel, said outer barrel is slid over said inner barrel during assembly, wherein the swivelable adapter device is held together with a holding ring permanently affixed near a forward end of said inner barrel once said outer barrel is slid onto said inner barrel, and when once permanently assembled, said outer barrel is rotatable around said inner barrel, causing rotation of said work tool plate, the notch plate and locking latch holding said work tool plate in various positions after said work tool plate is rotated. ### Claim 2 (depends on 1) The swivelable adapter device of claim 1, wherein said mounting plate is machined to accept the inner barrel outside diameter and wherein said mounting plate is rigidly affixed near an end of said inner barrel. ### Claim 3 (depends on 1) The swivelable adapter device of claim 1, wherein said work tool plate is machined to allow passage of said inner pipe through said work tool plate so as to establish a clearance between said inner barrel and said work tool plate. ### Claim 4 (depends on 1) The swivelable adapter of claim 1, wherein a reinforcing work tool plate is machined to accept an outer barrel outside diameter and wherein said reinforcing work tool plate is permanently affixed to said outer barrel near a forward end of said outer barrel and wherein said reinforcing work tool plate is permanently affixed to said work tool plate on an aft side of said work tool plate. ### Claim 5 (depends on 1) The swivelable adapter device of claim 1, wherein said outer barrel is permanently joined to said work tool plate at a forward end of said outer barrel and at an aft side of said work tool plate. ### Claim 6 (depends on 1) The swivelable adapter device of claim 1, wherein said mounting plate that is permanently affixed to said inner barrel near an aft end of said inner barrel, acts as a mount surface for skid steer loader arms of the skid steer loader. ### Claim 7 (depends on 1) The swivelable adapter device of claim 1, wherein said work tool plate is permanently affixed to said outer barrel and therein functions to accept a variety of commercial skid steer attachment work tools. ### Claim 8 (depends on 1) The swivelable adapter device of claim 1, wherein when said swivelable adapter device is mounted on a skid steer loader using said mounting plate, such that said mounting plate is fixed in position with skid steer loader lifting arms. ### Claim 9 A swiveable adapter device for a skid steer loader comprising: a mounting plate; a forward reinforcing mounting plate; an aft reinforcing mounting plate affixed to an inner barrel, the aft reinforcing plate contacting the mounting plate, the forward reinforcing mounting plate contacting the mounting plate, the mounting plate being positioned between the forward reinforcing mounting plate and the aft reinforcing mounting plate; a work tool plate affixed to an outer barrel; and a notch plate contacting the forward reinforcing plate and coupled to the outer barrel, the notch plate engaging a locking latch, wherein an outer barrel inside dimension is greater than an inner barrel outside dimension to allow clearance for the outer barrel to slide over the inner barrel, wherein said work tool plate is affixed to the outer barrel, the outer barrel is slid over the inner barrel during assembly, and wherein when once permanently assembled, the outer barrel is rotatable around the inner barrel, causing rotation of the work tool plate, the notch plate and locking latch holding the work tool plate in various positions after the work tool plate is rotated. ### Claim 10 (depends on 9) The swivelable adapter device of claim 9, wherein the swivelable adapter device is held together with a holding ring permanently affixed near a forward end of the inner barrel once the outer barrel is slid onto the inner barrel. ### Claim 11 (depends on 9) The swivelable adapter device of claim 9, wherein the work tool plate functions to accept a variety of commercial skid steer attachment work tools. ### Claim 12 (depends on 9) The swivelable adapter device of claim 9, wherein the locking latch is coupled to the mounting plate. ### Claim 13 (depends on 9) The swivelable adapter device of claim 9, wherein the notch plate comprises a plurality of notches that engage with the locking latch. ### Claim 14 (depends on 13) The swivelable adapter device of claim 13, wherein the plurality of notches extend along an outer periphery of the notch plate over a distance comprising about one-half of a circumference of the notch plate. ### Claim 15 A swiveable adapter device for a skid steer loader comprising: a mounting plate; a forward reinforcing mounting plate; an aft reinforcing mounting plate affixed to an inner barrel, the aft reinforcing plate contacting the mounting plate, the forward reinforcing mounting plate contacting the mounting plate, the mounting plate being positioned between the forward reinforcing mounting plate and the aft reinforcing mounting plate; a work tool plate affixed to an outer barrel; and means for holding the work tool plate in various positions, the means for holding contacting the forward reinforcing plate and coupled to the outer barrel, wherein an outer barrel inside dimension is greater than an inner barrel outside dimension to allow clearance for the outer barrel to slide over the inner barrel, wherein said work tool plate is affixed to the outer barrel, the outer barrel is slid over the inner barrel during assembly, and wherein when once permanently assembled, the outer barrel is rotatable around the inner barrel, causing rotation of the work tool plate, the means for holding secures the work tool plate in a second position after the work tool plate is rotated from the first position to the second position. ### Claim 16 (depends on 15) The swivelable adapter device of claim 15, wherein the means for holding comprises a notch plate engaging a locking latch. ### Claim 17 (depends on 16) The swivelable adapter device of claim 16, wherein the locking latch is coupled to the mounting plate. ### Claim 18 (depends on 16) The swivelable adapter device of claim 16, wherein the notch plate comprises a plurality of notches that engage with the locking latch. ### Claim 19 (depends on 18) The swivelable adapter device of claim 18, wherein the plurality of notches extend along an outer periphery of the notch plate over a distance comprising about one-half of a circumference of the notch plate. ### Claim 20 (depends on 15) The swivelable adapter device of claim 15, wherein the work tool plate functions to accept a variety of commercial skid steer attachment work tools.
