Abstract
Abstract A cylinder loading tool for loading pins and springs into a pin tumbler cylinder for a pin tumbler lock set includes a rod, longer than the pin tumbler cylinder, having a slot extending therein from end to end with axially aligned, radial pin bores in the rod intersecting the slot together with a cylindrical sleeve adapted to fit over the rod and together with a slide of generally rectangular configuration adapted to fit readily within the slot and having an inclined cam surface along one side adapted to abut a pin and spring combination in one of the radial bores in the rod and to press such pin and spring combination outwardly against the sleeve or into the cylinder.

Claim 1
Independent Claim
214 words
A cylinder loading tool for loading pins and springs into a pin tumbler cylinder having an axial bore and having a plurality of axially aligned radial pin holes spaced apart within a predetermined axial length and intersecting said axial bore comprising a rod adapted to fit axially into said bore and having a length greater than said predetermined length, said rod having a longitudinally extending, open ended, radial slot of predetermined depth therein and having a plurality of axially aligned radial bores therein spaced apart within said predetermined axial length to correspond to said pin holes and intersecting said slot, a cylindrical member having a solid portion of substantially said predetermined axial length and adapted to slide over said rod with said solid portion covering said radial bores in said rod, and a generally rectangular slide of at least the length of said rod, of a thickness slidably filling said slot, of a width substantially the same as said predetermined depth and having along one side edge a cam surface at an angle effective to lift a pin in one of said radial bores out of said radial bore when said radial bore is uncovered and said cam surface abuts the end of said pin and said slide is moved axially within said slot.
Claim 2
Dependent Claim
214 words
A cylinder loading tool for loading pins and springs into a pin tumbler cylinder having an axial bore and having a plurality of axially aligned radial pin holes spaced apart within a predetermined axial length and intersecting said axial bore comprising a rod adapted to fit axially into said bore and having a length greater than said predetermined length, said rod having a longitudinally extending, open ended, radial slot of predetermined depth therein and having a plurality of axially aligned radial bores therein spaced apart within said predetermined axial length to correspond to said pin holes and intersecting said slot, a cylindrical member having a solid portion of substantially said predetermined axial length and adapted to slide over said rod with said solid portion covering said radial bores in said rod, and a generally rectangular slide of at least the length of said rod, of a thickness slidably filling said slot, of a width substantially the same as said predetermined depth and having along one side edge a cam surface at an angle effective to lift a pin in one of said radial bores out of said radial bore when said radial bore is uncovered and said cam surface abuts the end of said pin and said slide is moved axially within said slot.
Claim 3
Dependent Claim
21 words
A tool as in claim 1 including means defining marking grooves on said rod and spaced apart said predetermined axial length.
Claim 4
Dependent Claim
23 words
A tool as in claim 1 in which said radial bores in said rod extend substantially to the bottom of said slot therein.
Claim 5
Dependent Claim
16 words
A tool as in claim 1 in which said cylindrical member is said pin tumbler cylinder.
Claim 6
Dependent Claim
14 words
A tool as in claim 1 in which said cylindrical member is a sleeve.
Claim 7
Dependent Claim
27 words
A tool as in claim 5 in which said sleeve is provided with an axially extending edge notch having a width just sufficient to receive said slide.
Claim 8
Dependent Claim
52 words
A tool as in claim 5 in which said sleeve is provided with a radial extension disposed along the length thereof, said extension including axially aligned radially extending pin bores, and a longitudinally extending open ended slot intersecting said pin bores, said slot having a width just sufficient to receive said slide.
