Abstract

The level-adjusting apparatus adjusts the level of a tool such as a router having a bit for cutting a piece of work on a working surface. The apparatus has a carriage on which the routes is mounted. The carriage is located beneath the working surface and its bit projects above the surface. The carriage may be raised and lowered by means of a handle above the working surface. The handle is removable so t at once the router is in position the handle may be removed so that it does not interfere with the routing operation.

Claims (18)

1. A level-adjusting apparatus for adjusting the level of a tool having an implement for cutting a piece of work on a working surface on which the work to be cut is placed, said level adjusting apparatus comprising: a carriage mounted beneath said working surface and adapted to support said tool such that said cutting implement projects above said working surface; means for altering the level of said carriage; and a handle mounted above said working surface and operatively connected to and activating said altering means.
2. The level-adjusting apparatus as claimed in claim 1 wherein said altering means includes a spindle threadably mounted to said carriage, said handle being mounted for rotation and being operatively connected to said spindle for causing said spindle to rotate with resulting alteration in the level of said carriage.
3. The level-adjusting apparatus as claimed in claim 1 wherein said handle is removably mounted to said working surface.
4. The level-adjusting apparatus as claimed in claim 3 further including a rotary element mounted for rotation beneath said working surface and operatively connected to said spindle, said rotary element having a space defined by an inner wall, said space communicating with an aperture formed in said working surface, said handle having a stem receivable in said space and having an outer wall which contacts said inner wall and which, when said handle is rotated, causes a like rotation of said inner wall with resulting alteration in the level of said carriage.
5. The level-adjusting apparatus as claimed in claim 1 further including a rotary element mounted for rotation beneath said working surface, said element having a vertically extending space defined by an inner wall, said space communicating with an aperture formed in said working surface, said altering means being operatively connected to said rotary element such that rotation of said rotary element causes said altering means to adjust the level of said carriage, said handle having a stem removably received in said aperture and said space and when therein said handle is above said working surface and said stem contacts said inner wall such that rotation of said handle causes a like rotation of said rotary element.
6. The level-adjusting apparatus as claimed in claim 5 wherein said altering means is separated horizontally from said space such that any debris which is generated by cutting of said work piece on said working surface and which falls downwardly into said aperture falls through said space and exits downwardly of said rotary element without contacting said altering means.
7. The level-adjusting apparatus as claimed in claim 4 further including a first wheel mounted to said rotary element, a second gear wheel mounted to said spindle, said gear wheels being horizontally spaced and operatively interconnected.
8. The level-adjusting apparatus as claimed in claim 4 further including a first wheel mounted to said rotary element, a second wheel mounted to said spindle, said gear wheels being horizontally spaced and operatively interconnected such that any debris which is generated by cutting of said work piece on said working surface and which falls downwardly into said aperture falls through said space and exits downwardly of said rotary element without contacting said spindle.
9. The level-adjusting apparatus as claimed in claim 1 wherein said spindle has threads which mate with threads formed in said carriage, said apparatus further having means for preventing slippage between the threads of said spindle and the threads of said carriage.
10. The level-adjusting apparatus as claimed in claim 2 wherein said spindle has threads which mate with threads formed in said carriage, said apparatus further including a collar threadably connected to said sleeve; and resilient means disposed between said collar and said carriage.
11. The level-adjusting apparatus as claimed in claim 2 wherein said spindle has threads which mate with threads formed in said carriage, said apparatus further including a collar having threads which mate with the threads of said spindle; resilient means disposed between said collar and said carriage, said collar upon rotation in one direction advancing toward said carriage and applying pressure to said resilient means with resulting counter pressure being applied to said sleeve by said resilient means such that the threads of said collar move into contact with the threads of said sleeve and frictionally resist slippage between the threads of said spindle and said carriage.
12. The level-adjusting apparatus as claimed in claim 11 further including stop means for preventing said collar from rotating on said spindle, said collar having an outer wall having a plurality of longitudinally extending grooves formed therein, said stop means being removably disposed in any one of said grooves and when therein preventing said collar from rotating on said spindle.
13. The level-adjusting apparatus as claimed in claim 11 further including stop means for preventing said collar from rotating on said spindle, said collar having an outer wall in which a plurality of radially extending threaded openings are formed, said stop means being removably received in any one of said openings and when therein preventing said collar from rotating on said spindle
14. The level-adjusting apparatus as claimed in claim 9 further including means for removably interconnecting said collar to said carriage to prevent rotation of said collar on said sleeve.
15. A level-adjusting apparatus for adjusting the level of a router having a bit for cutting a piece of work on a working surface on which the work to be cut is placed, said level adjusting apparatus comprising: a carriage mounted beneath said working surface and adapted to support said router such that said bit projects above said working surface; means for altering the level of said carriage; and a handle operatively connected to and activating said altering means.
16. The level-adjusting apparatus as claimed in claim 15 wherein said handle is mounted above said working surface.
17. The level-adjusting apparatus as claimed in claim 15 wherein said altering means includes a spindle threadably mounted to said carriage and a rotary element mounted for rotation beneath said working surface, said element having a vertically extending space defined by an inner wall, said space communicating with an aperture formed in said working surface, said spindle being operatively connected to said rotary element such than rotation of said rotary element causes said spindle to rotate with resulting alteration in the level of said carriage.
18. The level-adjusting apparatus as claimed in claim 17 wherein said handle is mounted above said working surface and has a stem removably received in said aperture and said space and when therein said stem contacts said inner wall such that rotation of said handle causes a like rotation of said rotary element.
