Abstract
Abstract A caliper brake for cycles and the like in which a bridge piece secures the caliper brake to the cycle frame and a pair of arms are pivotally mounted and carry brake jaws which press against the cycle wheel when a cable is drawn. According to the invention at least one of the arms and the support are connected by a threaded member and are respectively tapped so as to receive the threaded member as a screw-and-nut connection. A clearance is provided axially to permit the arm to move slightly as it is rotated about the screw member on the latter.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
160 words
A caliper brake for cycles and the like, comprising: a bridge member adapted to be mounted upon a cycle; a pair of arm members pivotally mounted about at least one axis fixed relative to said bridge member for swinging movement in opposite senses; cable actuating means connected to said arm members for swinging same in said opposite senses; respective brake shoes on said arm members displaceable against a wheel upon swinging movement of said arm members in said opposite senses; and a shaft being coincident with said at leaast one axis and being secured to said bridge member said shaft having a threaded portion, one of said arm members being formed with an internally threaded bore of the same diameter as said threaded portion and screwed onto the latter with axial clearance from another of said members permitting rotation of said one of said arm members about said shaft with slight axial displacement of said one of said arm members.
Claim 2
Dependent Claim
160 words
A caliper brake for cycles and the like, comprising: a bridge member adapted to be mounted upon a cycle; a pair of arm members pivotally mounted about at least one axis fixed relative to said bridge member for swinging movement in opposite senses; cable actuating means connected to said arm members for swinging same in said opposite senses; respective brake shoes on said arm members displaceable against a wheel upon swinging movement of said arm members in said opposite senses; and a shaft being coincident with said at leaast one axis and being secured to said bridge member said shaft having a threaded portion, one of said arm members being formed with an internally threaded bore of the same diameter as said threaded portion and screwed onto the latter with axial clearance from another of said members permitting rotation of said one of said arm members about said shaft with slight axial displacement of said one of said arm members.
Claim 3
Dependent Claim
45 words
The caliper brake defined in claim 1 wherein said arm members are pivotal about a common axis, said brake further comprising a spring bearing on said arm members to urge said brake shoes away from said wheel, said spring being engaged by said bridge member.
Claim 4
Dependent Claim
34 words
The caliper brake defined in claim 2 wherein said bridge member is formed with an internally threaded bore of the same diameter as said threaded portion of said shaft and screwed onto the latter.
Claim 5
Dependent Claim
33 words
The caliper brake defined in claim 3 wherein both of said arm members are provided with respective threaded bores of the same diameter as said threaded portion and are screwed onto the latter.
Claim 6
Dependent Claim
39 words
The caliper brake defined in claim 3 wherein said bridge member is formed with a boss extending in the direction of said one of said arm members, the other of said arm members being rotatably mounted on said boss.
Claim 7
Dependent Claim
34 words
The caliper brake defined in claim 5 wherein said boss has a frustoconical configuration and said other of said arm members has a nonthreaded bore of frustoconical configuration complementary to that of said boss.
Claim 8
Dependent Claim
31 words
The caliper brake defined in claim 3 wherein said shaft is formed with a shoulder, said bridge member being threaded onto said portion of said shaft to bottom against said shoulder.
Claim 9
Dependent Claim
19 words
The caliper brake defined in claim 7 wherein said bridge member is formed with a recess receiving said shoulder.
Claim 10
Dependent Claim
37 words
The caliper brake defined in claim 3 wherein said shaft is formed with a nonthreaded portion adjacent said threaded portion, said bridge member being threaded onto said threaded portion until it is blocked by said nonthreaded portion.
Claim 11
Dependent Claim
18 words
The caliper brake defined in claim 2 wherein said bridge member is a single piece with said shaft.
Claim 12
Dependent Claim
28 words
The caliper brake defined in claim 1 wherein said bridge member is provided with a second shaft, each shaft forming a respective axis for a respective arm member.
Claim 13
Dependent Claim
24 words
The caliper brake defined in claim 1 wherein the other of said arm members and said bridge member are also threaded onto said shaft.
Claim 14
Dependent Claim
53 words
The caliper brake defined in claim 1 wherein one of the other of said arm members and said bridge member is formed with a boss, and the other of the other of said arm members and said bridge member is provided with a nonthreaded bore receiving said boss and is freely rotatable thereon.
Claim 15
Dependent Claim
30 words
The caliper brake defined in claim 1 wherein said bridge member is formed integrally with said shaft and the other of said arm members is also threaded onto said shaft.
