Abstract
Abstract A device for securing one body to another body, for example a switch cam to a cam drum which has a groove for the reception of the first-mentioned body which may be clamped to the sidewalls of the groove under the action of a screw. According to the invention, the first-mentioned body has a holding part adapted to be located on one rim of the groove, this holding part projecting laterally and partially bridging the groove, and further has a wedge-shaped part projecting into the groove on one side thereof. This wedge-shaped part cooperates with a clamping piece threadably tightened by means of a screw designed as a head screw. The clamping piece is arranged adjacent the wedge-shaped part in the groove to tension the first-mentioned body in the groove, and the screw is supported on the holding part through which it passes and is freely displaceable axially relative thereto.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
230 words
A device for securing a first body to a second body, comprising in combination: a. a first body; b. a second body provided with groove means having first and second opposed inner walls for receiving said first body; c. a clamping member disposed in said groove means; d. a screw-tightening means received by said clamping member and extending with play through said first body and freely displaceable therein; e. said groove means having an outer surface, said first body bearing against and bridging said outer surface of said groove means; f. said first body possessing a substantially L-shaped crosssectional configuration and including a first leg portion and a second substantially wedge-shaped in longitudinal cross section leg portion; g. said first leg portion bearing against said outer surface of said groove means; h. said second substantially wedge-shaped leg portion extending into said groove means and laterally bearing along the outside face against said first inner wall; i. said clamping member laterally bearing against said wedgeshaped leg portion and said second inner wall of said groove means; j. said second leg portion tapering along the inside face facing said first leg portion and said second inner wall; and k. said clamping member bearing against said inside tapered face, whereby pivoting of said second leg portion is prevented so as to maintain said bearing relationship between said outer surface and said first leg.
Claim 2
Independent Claim
230 words
A device for securing a first body to a second body, comprising in combination: a. a first body; b. a second body provided with groove means having first and second opposed inner walls for receiving said first body; c. a clamping member disposed in said groove means; d. a screw-tightening means received by said clamping member and extending with play through said first body and freely displaceable therein; e. said groove means having an outer surface, said first body bearing against and bridging said outer surface of said groove means; f. said first body possessing a substantially L-shaped crosssectional configuration and including a first leg portion and a second substantially wedge-shaped in longitudinal cross section leg portion; g. said first leg portion bearing against said outer surface of said groove means; h. said second substantially wedge-shaped leg portion extending into said groove means and laterally bearing along the outside face against said first inner wall; i. said clamping member laterally bearing against said wedgeshaped leg portion and said second inner wall of said groove means; j. said second leg portion tapering along the inside face facing said first leg portion and said second inner wall; and k. said clamping member bearing against said inside tapered face, whereby pivoting of said second leg portion is prevented so as to maintain said bearing relationship between said outer surface and said first leg.
Claim 3
Dependent Claim
17 words
The device of claim 1, wherein said first and second leg portions are integral with one another.
Claim 4
Dependent Claim
55 words
The device as claimed in claim 1, wherein said first body defines a holding part having two lateral support projections on a shoulder portion thereof resting on said outer surface of said groove means and further possesses a cutout therebetween forming a space between said shoulder portion and the outer surface of said groove means.
Claim 5
Independent Claim
210 words
A device for securing a first body to a second body, comprising in combination; a. a first body; b. a second body provided with groove means having inner walls for receiving said first body; c. a clamping member disposed in said groove means; d. a screw-tightening means received by said clamping member and extending with play through said first body and freely displaceable therein; e. said groove means having an outer surface, said first body bearing against and bridging said outer surface of said groove means; f. said first body possessing a substantially L-shaped cross-sectional configuration and including a first leg portion and a second substantially wedge-shaped leg portion; g. said first leg portion bearing against said outer surface of said groove means; h. said second substantially wedge-shaped leg portion extending into said groove means; i. said clamping member laterally bearing against said wedge-shaped leg portion and an inner wall of said groove means; j. said screw member comprising a head screw which piercingly extends through said first leg portion with radial play such that said clamping member which is constructed at its widest location to be considerably narrower than said groove means upon tightening said screw means can be displaced in a direction substantially transverse to said groove means.
Claim 6
Independent Claim
210 words
A device for securing a first body to a second body, comprising in combination; a. a first body; b. a second body provided with groove means having inner walls for receiving said first body; c. a clamping member disposed in said groove means; d. a screw-tightening means received by said clamping member and extending with play through said first body and freely displaceable therein; e. said groove means having an outer surface, said first body bearing against and bridging said outer surface of said groove means; f. said first body possessing a substantially L-shaped cross-sectional configuration and including a first leg portion and a second substantially wedge-shaped leg portion; g. said first leg portion bearing against said outer surface of said groove means; h. said second substantially wedge-shaped leg portion extending into said groove means; i. said clamping member laterally bearing against said wedge-shaped leg portion and an inner wall of said groove means; j. said screw member comprising a head screw which piercingly extends through said first leg portion with radial play such that said clamping member which is constructed at its widest location to be considerably narrower than said groove means upon tightening said screw means can be displaced in a direction substantially transverse to said groove means.
