Abstract
Abstract A belt Guard is supported by the spindle carrying one sheave engaged with the belt being guarded, and is also supported by an adjustable strut assembly interconnecting the guard with the machine frame supporting the spindle. This arrangement provides for angular adjustment of the guard about the spindle axis to accomodate various positions of a second sheave engaging the belt.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
165 words
In combination with a machine having a headstock frame, a spindle rotatably mounted in said frame, and sheave means mounted on said spindle, said machine also having drive means for said spindle including a power head and a driving sheave normally carried by said power head, and also including belt means normally interengaged with said sheaves in power-transfer relationship, a guard assembly for said belt means and sheaves comprising: means forming a bearing ring carried by said spindle and rotatable with respect thereto; a first guard housing element having an opening normally traversed by said spindle, said first guard housing element being secured to said ring; stabilizing means securing said first guard housing element against rotation with respect to said frame; and a second guard housing element normally disposed with respect to said first guard housing element to define therewith an enclosure for said belt means and sheaves, and further including means attaching said guard housing elements together at positions remote from said belt means.
Claim 2
Dependent Claim
165 words
In combination with a machine having a headstock frame, a spindle rotatably mounted in said frame, and sheave means mounted on said spindle, said machine also having drive means for said spindle including a power head and a driving sheave normally carried by said power head, and also including belt means normally interengaged with said sheaves in power-transfer relationship, a guard assembly for said belt means and sheaves comprising: means forming a bearing ring carried by said spindle and rotatable with respect thereto; a first guard housing element having an opening normally traversed by said spindle, said first guard housing element being secured to said ring; stabilizing means securing said first guard housing element against rotation with respect to said frame; and a second guard housing element normally disposed with respect to said first guard housing element to define therewith an enclosure for said belt means and sheaves, and further including means attaching said guard housing elements together at positions remote from said belt means.
Claim 3
Dependent Claim
15 words
A combination as defined in claim 1, wherein said guard elements are normally telescopically interengaged.
Claim 4
Dependent Claim
24 words
A combination as defined in claim 1, wherein said second guard element has an open end adapted to receive portions of said driving sheave.
Claim 5
Dependent Claim
48 words
A combination as defined in claim 3, wherein said power head is moveable with respect to said frame in a manner to increase and decrease the distance between said sheaves, said power head being on the opposite side of said belt means from said first guard housing element.
Claim 6
Dependent Claim
135 words
In combination with a machine having a headstock frame, a spindle rotatably mounted on said spindle, said machine also having drive means for said spindle including a power head and a driving sheave normally carried by said power head, and also including belt means normally interengaged with said sheaves in power-transfer relationship, a guard assembly for said belt means and sheaves comprising: means forming a bearing ring carried by said spindle and rotatable with respect thereto; a guard housing element having an opening norMally traversed by said spindle, said guard housing element being secured to said ring; and stabilizing means securing said guard housing element against rotation with respect to said frame, said stabilizing means including an adjustable strut assembly interconnecting said guard housing element and said frame at a position remote from said spindle.
Claim 7
Dependent Claim
135 words
In combination with a machine having a headstock frame, a spindle rotatably mounted on said spindle, said machine also having drive means for said spindle including a power head and a driving sheave normally carried by said power head, and also including belt means normally interengaged with said sheaves in power-transfer relationship, a guard assembly for said belt means and sheaves comprising: means forming a bearing ring carried by said spindle and rotatable with respect thereto; a guard housing element having an opening norMally traversed by said spindle, said guard housing element being secured to said ring; and stabilizing means securing said guard housing element against rotation with respect to said frame, said stabilizing means including an adjustable strut assembly interconnecting said guard housing element and said frame at a position remote from said spindle.
