In more detail, as shown in Fig. 1, the end frame
3 of the jig 1 comprises an elongated end plate 15 mounted on end mounting blocks 17, 19 by screws 21. The first drill guide opening 9 is centrally located in the end plate 15 between the mounting blocks 17, 19 and is rectangular in shape. A first mounting post 23 projects up from the top mounting block 17 whereas a second mounting post 24 projects down from the bottom mounting block 19. The posts 23 and 24 are centrally located on the blocks 17 and 19 and are pivotally mounted on these blocks by suitable means (not shown3.
Each side frame 5, 7 comprises a relatively thin side plate 25 having top and bottom mounting ears 27, 29 extending outwardly from the front side 31 of the plate 25.
A large, rectangular locating opening 33 is provided in the side plate 25 between the front side 31 and the rear side 35. The outer face 37 of the plate 25 is recessed inwardly to form a stepped portion 39 as shown in Fig. 5, from the opposite side 35 and about the locating opening 33. ~ template 41 is adapted to fit snugly within the stepped portion 39 of the opening 33. A screw 45 fixes the template 41 which over-lies the opening 33 to the side plate 25. The template 41 has the second and third drill guide openings 11, 13 therein.
~s can be easily understood, the template 41 can form one of a set of templates having openings 11 and 13 of different size and/or different locations. I'he proper pair of templates 41 Eor a fiven door ~.
lock to be installed, is selected from the set of tem-plates and mounted in the two side plates 25, forming part of the side frames 5 and 7, by means of the screws 45.
Means are provided for mounting the side frames 5, 7 on the end frame 3 for movement toward or away from each other. These mounting means comprises a first guide pin 51 on the end frame 3 extending transversely through the first top mounting post 23, and centered with respect to the post 23, and a second mounting pin 53 on the end Erame 3 extending transversely through the second bottom mounting post 24, and centered with respect to the post 24.
The guide pins 51, 53 are parallel.. Each side plate 25 of the side frames 5, 7 has a first through bore 55 in the top mounting ear 27 and a second through bore 57 in the bottom mounting ear 29. The side frame 5 is slidably mounted on one side 59, 61 of the pins 51, 53 via its bores 55, 57 in its side plate 25 while the side frame 7 is slidably mounted on the other side 63, 65 of the pins 51, 53 via its bores 55, 57 in its side plate 25, as sh~wn in Fig. 3.
Means are provided for moving the side frames 5, 7 toward or away from each other while slidably mounted on the guide pins 51, 53 on the end frame 3. The moving means comprises a first adjustment bolt 71 passing through the f.irst post 24 on the en~ frame 3 and a second adjustment bolt 73, identical to the first bolt 71, passing through the second post 24. Since the bolts 71, 73 are identical only one will be described in detail. The adjustment bolt 71, as shown in Fig. 6, is rotatably mounted in a through bore 75 in the post 24, parallel to the pin 51. A restrain-ing screw 27 is threaded into the first post 17 through a tapped hole 79, from its outer end 81. The restraining screw 77 extends transverse to the bolt 71 and its inner end 83 enters a circul.~r groove 85 on the bolt 71 located about midway of its length. With the screw 77 located . - 5 ~
19'73 within the groove 85 of the bolt 71, the bolt 71 can be rotated within the bore 75 in the post 23 without moving transversely of the post 23.
The bolt 71 is provided with a thread 87 of one hand at its outer end 89 from the groove 85 and a thread 91 of opposite hand at its inner end 93 from the groove 85.
An enlarged, threaded bore 95 is provided in the ear 27 of the side plate ~5 in the side frame 5. The bore 95 is just above the bore 55 in the ear 27 for the guide pin 51 and is axially aligned with the bore 75 in the post 23. An adapter nut 97, having a threaded bore 99, is treaded into the bore 95 in the ear 27 of the side plate 25 and onto the threaded outer side 89 of the bolt 71. The pitch of the bores 95 and 99 is the same. The adapter nut 97 is tightly locked in the ear 27 while the bolt 71 can freely move relative to the ear 27. A threaded bore 101 is also provided in the ear 27 in the side plate 25 of the other side frame 7. The bore 101 is aligned with the bore 95 in the side frame 5 and the bore 75 in the post 17, and it threadably receives the threaded inner end 93 of the bolt 71. Rotation of the bolt 71 by a knob 103 at the inner end 93 of the bolt 71 in one direction will move the side frames 5, 7 toward each other whereas rotation of the bolt 71 in the opposite direction will move the side frames 5, 7 away from each other. It will be understood that both bolts 71, 73 are rotated generally together in such a manner that the top and bottom ends of the side frames move generally together without binding on the guide pins 51, 53.
The side frames 5, 7 can thus be adjusted to have the jig 3Q 1 fit on doors of different thickness, and to then be tightly clamped onto the door so that holes D>~, <~E~ can be drilled through the door in the right location through the openings 11, 13 in the side frames 5, 7.
The jig 1 is also provided with means for varying ~U~73 the size of the drill guide opening 9 in the end frame 3.
Preferably both the length of the opening and its width can be ~aried. In more detail, the means for varying the width of the opening 9 comprises a pair of bars 115, 117 mounted behind the end plate 15 of the end frame 3 with one bar 115 on one side of opening 9 and with the other bar 117 on the other side of opening, as shown in FigO 7. The bars 115, 117 are parallel to each other and are mounted on the mounti.ng blocks 17, 19 of the end frame 3 for movement toward or away from each other adjacent opening 9. As the bars 115, 117 move toward each other, they pass inwardly of the sides 119, 121 of the opening 9 effectively narrowing it.
The bars 115, 117 are mounted at one end 123, 125 respectively, on a third adjustment bolt 127 and at their other end 129, 131 respectively, to a fourth adjustment bolt 133. Each of the third and fourth adjustment bolts 127, 133 has an outer portion 135 with threads of one hand thereon, an unthreaded central portion 137 and an inner portion 139 with threads of the other hand thereon. The outer portion 135 is slightly smaller in diameter than the central or inner portions 137, 139. The bar 115 has a threaded bore 141 as shown in Fig. 8 at its ends 123, 129 to receive the threaded outer portion 135 of the bolts 127, 133. The bar 117 has a larger threaded bore 145 at its ends 125, 131 to receive the threaded inner portion 139 of the bolts 127, 133.
The bolt 127 is rotatably mounted, via its cen-tral portion 137, in a centrally located, inwardly directed, projection 153 of the mounting block 17. The bolt 127 passes through a bore 155 in the projection 153. C-clips 157, 159 cooperate with grooves (not shown) on the central portion 137 of bolt 127 to prevent lateral movement of bolt 127 with respect to projection 153, the C-clips 157, 159 3'~3 abutting the sides 165, 167 of the projection 153. The bolt 127 passes through a ~ole 169 in the side wall 171 of end plate 15 and the knob 173 of the bolt 127 lies outside the end plate 15 adjacent the side wall 171. The bolt 133 is similarly constructed and mounted at the other end of the end frame 3 to the bars 115, 117 and the mounting block 19 .
Rotation of the bolts 127, 133 using their knobs 173, in one direction will move the bars 115, 117 toward one another, thereby narrowing opening 9. Rotation of the bolts 127, 133 in the opposite direction will move the bars 115, 117 away from one another, thereby widening opening 9 until the bars 115, 117 move outwardly past the sides 119, 121 of the opening 9 giving maximum width.
A pair of sliding plates 205, 207 are employed to shorten the opening 9. Since each plate 205, 207 is the same, only one will be described in detail. The plate 205, as shown in FigsO 9 and 10, is sized to slide against the back face of the outer wall 209 of the end plate 15 and between its side walls 171, 211. The plate 205 has an extension 213, 215 on each side 217, 219 which extends transverse to the main body 221 of plate 205. The exten-sions 213l 215 lie adjacent to the side walls 171, 211 respectively while the main body 221 of the plate 205 lies adjacent the outer wall 209 of the end plate 15. The plate 205 also has a leading edge 223 which is parallel to one end edge 225 of the opening 9~
A tubular member 227 is fixed to the inside of one extension 215 of the plate 205, the axis of the member 227 extending transverse to the leading edge 223. The bore 229 of the member 227 is threaded one hand. The plate 207 differs Erom the plate 205 only in having its tubular member 227 with a slightly larger bore 229 and threaded to the opposite hand of the threads in the bore 229 on the 7~
plate 205.
A fifth adjustment bolt 231 is rotatably mounted in the end blocks 17, 19 adjacent one side of the blocks 17, 19~ The bolt 231 passes through a bo~e 237 in the end block 17 and a bore 239 in the end block 19. The outer portion 241 of the bolt 231, except for outermost portion 243 in the bore 239 is threaded in one hand. The inner portion 245 of the bolt 231, except for its innermost por-tion 247 passing through the bore 237, is threaded in the opposite hand. The outer and outermost portions 241, 243 of the bolt 231 are slightly smaller in diameter than the inner and innermost portions 245, 247 of the bolt 231.
The innermost portion 247 of the bolt 231 projects out-wardly of the end frame 3 in such a manner that the bolt 231 can be rotated within the end blocks 17, 19. C-clips 251, 253, cooperating with grooves (not shown) on the bolt 231, lock the bolt 231 in place relative to the end block 17 so that the bolt cannot move transversely of the end blocks 17, 19. The outer portion 241 of the bolt 231 is threaded through the tubular member 227 on the sliding plate 205 while the inner portion 245 of the bolt ~31 is threaded through the tubular member 227 on the sliding plate 207. Rotation of the adjustment bolt 231 in one direction will moY~ the plates 205, 207 toward each other, past the end edges 225, 261 of the opening 9, thereby effectively reducing its length. Rotation of the adjust-ment bolt 231 in the opposite direction will move the plates 205, 207 toward each other past the end edges 225, 261 of the opening 9 thus effectively reducing its length. Rota-tion of the adjustment bolt 231 in the opposite direction will move the plates 205, 207 away from each other, thereby lengthening opening 9 until the plates 205, 207 move past the edges 225, 261 of the opening 9, thereby giving a maximum length to opening 9.
If desired, a stop screw 265 can be provided at each end of the jig l. Each stop screw 265 is threaded through a threaded bore in one eax 27, 29 of one side frame 5. A lock nut 269 is threaded onto the stop screw 265.
The stop screw 265 is threaded.through the ear 27, 29 to project past the ear a distance equal to the door thickness.
The lock nut 269 is then threaded tight against the ear 27, 29 to lock the stop screw 265 in place. The lateral adjust-ment screws 71, 73 are then operated to move the side frames 5, 7 together until the other side frame 7 abuts the end of the stop screws 265. The side frames 5, 7 are now spaced apart the desired distance to snugly fit onto the door.
Each side frame 5, 7 comprises a relatively thin side plate 25 having top and bottom mounting ears 27, 29 extending outwardly from the front side 31 of the plate 25.
A large, rectangular locating opening 33 is provided in the side plate 25 between the front side 31 and the rear side 35. The outer face 37 of the plate 25 is recessed inwardly to form a stepped portion 39 as shown in Fig. 5, from the opposite side 35 and about the locating opening 33. ~ template 41 is adapted to fit snugly within the stepped portion 39 of the opening 33. A screw 45 fixes the template 41 which over-lies the opening 33 to the side plate 25. The template 41 has the second and third drill guide openings 11, 13 therein.
~s can be easily understood, the template 41 can form one of a set of templates having openings 11 and 13 of different size and/or different locations. I'he proper pair of templates 41 Eor a fiven door ~.

These mounting means comprises a first guide pin 51 on the end frame 3 extending transversely through the first top mounting post 23, and centered with respect to the post 23, and a second mounting pin 53 on the end Erame 3 extending transversely through the second bottom mounting post 24, and centered with respect to the post 24.
The guide pins 51, 53 are parallel.. Each side plate 25 of the side frames 5, 7 has a first through bore 55 in the top mounting ear 27 and a second through bore 57 in the bottom mounting ear 29. The side frame 5 is slidably mounted on one side 59, 61 of the pins 51, 53 via its bores 55, 57 in its side plate 25 while the side frame 7 is slidably mounted on the other side 63, 65 of the pins 51, 53 via its bores 55, 57 in its side plate 25, as sh~wn in Fig. 3.
Means are provided for moving the side frames 5, 7 toward or away from each other while slidably mounted on the guide pins 51, 53 on the end frame 3. The moving means comprises a first adjustment bolt 71 passing through the f.irst post 24 on the en~ frame 3 and a second adjustment bolt 73, identical to the first bolt 71, passing through the second post 24. Since the bolts 71, 73 are identical only one will be described in detail. The adjustment bolt 71, as shown in Fig. 6, is rotatably mounted in a through bore 75 in the post 24, parallel to the pin 51. A restrain-ing screw 27 is threaded into the first post 17 through a tapped hole 79, from its outer end 81. The restraining screw 77 extends transverse to the bolt 71 and its inner end 83 enters a circul.~r groove 85 on the bolt 71 located about midway of its length. With the screw 77 located . - 5 ~
19'73 within the groove 85 of the bolt 71, the bolt 71 can be rotated within the bore 75 in the post 23 without moving transversely of the post 23.
The bolt 71 is provided with a thread 87 of one hand at its outer end 89 from the groove 85 and a thread 91 of opposite hand at its inner end 93 from the groove 85.
An enlarged, threaded bore 95 is provided in the ear 27 of the side plate ~5 in the side frame 5. The bore 95 is just above the bore 55 in the ear 27 for the guide pin 51 and is axially aligned with the bore 75 in the post 23. An adapter nut 97, having a threaded bore 99, is treaded into the bore 95 in the ear 27 of the side plate 25 and onto the threaded outer side 89 of the bolt 71. The pitch of the bores 95 and 99 is the same. The adapter nut 97 is tightly locked in the ear 27 while the bolt 71 can freely move relative to the ear 27. A threaded bore 101 is also provided in the ear 27 in the side plate 25 of the other side frame 7. The bore 101 is aligned with the bore 95 in the side frame 5 and the bore 75 in the post 17, and it threadably receives the threaded inner end 93 of the bolt 71. Rotation of the bolt 71 by a knob 103 at the inner end 93 of the bolt 71 in one direction will move the side frames 5, 7 toward each other whereas rotation of the bolt 71 in the opposite direction will move the side frames 5, 7 away from each other. It will be understood that both bolts 71, 73 are rotated generally together in such a manner that the top and bottom ends of the side frames move generally together without binding on the guide pins 51, 53.
The side frames 5, 7 can thus be adjusted to have the jig 3Q 1 fit on doors of different thickness, and to then be tightly clamped onto the door so that holes D>~, <~E~ can be drilled through the door in the right location through the openings 11, 13 in the side frames 5, 7.
The jig 1 is also provided with means for varying ~U~73 the size of the drill guide opening 9 in the end frame 3.
Preferably both the length of the opening and its width can be ~aried. In more detail, the means for varying the width of the opening 9 comprises a pair of bars 115, 117 mounted behind the end plate 15 of the end frame 3 with one bar 115 on one side of opening 9 and with the other bar 117 on the other side of opening, as shown in FigO 7. The bars 115, 117 are parallel to each other and are mounted on the mounti.ng blocks 17, 19 of the end frame 3 for movement toward or away from each other adjacent opening 9. As the bars 115, 117 move toward each other, they pass inwardly of the sides 119, 121 of the opening 9 effectively narrowing it.
The bars 115, 117 are mounted at one end 123, 125 respectively, on a third adjustment bolt 127 and at their other end 129, 131 respectively, to a fourth adjustment bolt 133. Each of the third and fourth adjustment bolts 127, 133 has an outer portion 135 with threads of one hand thereon, an unthreaded central portion 137 and an inner portion 139 with threads of the other hand thereon. The outer portion 135 is slightly smaller in diameter than the central or inner portions 137, 139. The bar 115 has a threaded bore 141 as shown in Fig. 8 at its ends 123, 129 to receive the threaded outer portion 135 of the bolts 127, 133. The bar 117 has a larger threaded bore 145 at its ends 125, 131 to receive the threaded inner portion 139 of the bolts 127, 133.
The bolt 127 is rotatably mounted, via its cen-tral portion 137, in a centrally located, inwardly directed, projection 153 of the mounting block 17. The bolt 127 passes through a bore 155 in the projection 153. C-clips 157, 159 cooperate with grooves (not shown) on the central portion 137 of bolt 127 to prevent lateral movement of bolt 127 with respect to projection 153, the C-clips 157, 159 3'~3 abutting the sides 165, 167 of the projection 153. The bolt 127 passes through a ~ole 169 in the side wall 171 of end plate 15 and the knob 173 of the bolt 127 lies outside the end plate 15 adjacent the side wall 171. The bolt 133 is similarly constructed and mounted at the other end of the end frame 3 to the bars 115, 117 and the mounting block 19 .
Rotation of the bolts 127, 133 using their knobs 173, in one direction will move the bars 115, 117 toward one another, thereby narrowing opening 9. Rotation of the bolts 127, 133 in the opposite direction will move the bars 115, 117 away from one another, thereby widening opening 9 until the bars 115, 117 move outwardly past the sides 119, 121 of the opening 9 giving maximum width.
A pair of sliding plates 205, 207 are employed to shorten the opening 9. Since each plate 205, 207 is the same, only one will be described in detail. The plate 205, as shown in FigsO 9 and 10, is sized to slide against the back face of the outer wall 209 of the end plate 15 and between its side walls 171, 211. The plate 205 has an extension 213, 215 on each side 217, 219 which extends transverse to the main body 221 of plate 205. The exten-sions 213l 215 lie adjacent to the side walls 171, 211 respectively while the main body 221 of the plate 205 lies adjacent the outer wall 209 of the end plate 15. The plate 205 also has a leading edge 223 which is parallel to one end edge 225 of the opening 9~
A tubular member 227 is fixed to the inside of one extension 215 of the plate 205, the axis of the member 227 extending transverse to the leading edge 223. The bore 229 of the member 227 is threaded one hand. The plate 207 differs Erom the plate 205 only in having its tubular member 227 with a slightly larger bore 229 and threaded to the opposite hand of the threads in the bore 229 on the 7~
plate 205.
A fifth adjustment bolt 231 is rotatably mounted in the end blocks 17, 19 adjacent one side of the blocks 17, 19~ The bolt 231 passes through a bo~e 237 in the end block 17 and a bore 239 in the end block 19. The outer portion 241 of the bolt 231, except for outermost portion 243 in the bore 239 is threaded in one hand. The inner portion 245 of the bolt 231, except for its innermost por-tion 247 passing through the bore 237, is threaded in the opposite hand. The outer and outermost portions 241, 243 of the bolt 231 are slightly smaller in diameter than the inner and innermost portions 245, 247 of the bolt 231.
The innermost portion 247 of the bolt 231 projects out-wardly of the end frame 3 in such a manner that the bolt 231 can be rotated within the end blocks 17, 19. C-clips 251, 253, cooperating with grooves (not shown) on the bolt 231, lock the bolt 231 in place relative to the end block 17 so that the bolt cannot move transversely of the end blocks 17, 19. The outer portion 241 of the bolt 231 is threaded through the tubular member 227 on the sliding plate 205 while the inner portion 245 of the bolt ~31 is threaded through the tubular member 227 on the sliding plate 207. Rotation of the adjustment bolt 231 in one direction will moY~ the plates 205, 207 toward each other, past the end edges 225, 261 of the opening 9, thereby effectively reducing its length. Rotation of the adjust-ment bolt 231 in the opposite direction will move the plates 205, 207 toward each other past the end edges 225, 261 of the opening 9 thus effectively reducing its length. Rota-tion of the adjustment bolt 231 in the opposite direction will move the plates 205, 207 away from each other, thereby lengthening opening 9 until the plates 205, 207 move past the edges 225, 261 of the opening 9, thereby giving a maximum length to opening 9.
If desired, a stop screw 265 can be provided at each end of the jig l. Each stop screw 265 is threaded through a threaded bore in one eax 27, 29 of one side frame 5. A lock nut 269 is threaded onto the stop screw 265.
The stop screw 265 is threaded.through the ear 27, 29 to project past the ear a distance equal to the door thickness.
The lock nut 269 is then threaded tight against the ear 27, 29 to lock the stop screw 265 in place. The lateral adjust-ment screws 71, 73 are then operated to move the side frames 5, 7 together until the other side frame 7 abuts the end of the stop screws 265. The side frames 5, 7 are now spaced apart the desired distance to snugly fit onto the door.
