Abstract

Abstract A drill press includes an overhead mount for supporting a power-operated drilling unit from an existing structure at locations above a work area, thereby enabling the accurate drilling of holes in large workpieces. An upright member is attached to one portion of the existing structure, such as a ceiling, and provides vertical support for a power-operated drilling unit. The upright member is extensible, enabling the drilling unit to be raised or lowered to accommodate workpieces of various sizes. Lateral support for the upright member is provided by brace members which connect the upright member to spaced portions of the existing structure.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 220 words
A drill press mounting assembly comprising: an upright member having connection means at one end thereof for detachably securing an electric drill thereto for use at a work station, overhead mount means including a pivotal connection attached to the other end of said upright member for supporting said upright member in swingable pendant relation therefrom, a pair of bracing members disposed respectively in angular relation to said upright member, said bracing members each having respective pivotal connections at each end thereof, said upright member and each of said bracing members respectively including telescopically extensible portions disposed between said connections thereof thereby to adjustably select a predetermined fixed length for said upright member and each of said bracing members, each said bracing member having its pivotal connection at one said end adjustably securable at selected positions to said upright member, and, overhead mount means attached respectively to the said pivotal connection at the other said end of each said bracing member, thereby to facilitate positioning of said mounting assembly as necessary by virtue of the said pivotal connections at each end of each said bracing member, whereby an electric drill secured to said pendant upright member is stabilized for drilling operations by said pair of angularly related bracing members through the respective overhead mounts thereof and of said pendant upright member.
Claim 2
Dependent Claim 220 words
A drill press mounting assembly comprising: an upright member having connection means at one end thereof for detachably securing an electric drill thereto for use at a work station, overhead mount means including a pivotal connection attached to the other end of said upright member for supporting said upright member in swingable pendant relation therefrom, a pair of bracing members disposed respectively in angular relation to said upright member, said bracing members each having respective pivotal connections at each end thereof, said upright member and each of said bracing members respectively including telescopically extensible portions disposed between said connections thereof thereby to adjustably select a predetermined fixed length for said upright member and each of said bracing members, each said bracing member having its pivotal connection at one said end adjustably securable at selected positions to said upright member, and, overhead mount means attached respectively to the said pivotal connection at the other said end of each said bracing member, thereby to facilitate positioning of said mounting assembly as necessary by virtue of the said pivotal connections at each end of each said bracing member, whereby an electric drill secured to said pendant upright member is stabilized for drilling operations by said pair of angularly related bracing members through the respective overhead mounts thereof and of said pendant upright member.
Claim 3
Dependent Claim 61 words
The drill press of claim 1 wherein the power operated drilling means includes: (a) a portable electric drill; (b) a slide carriage means for holding the portable electric drill relative to the workpiece; (c) connecting means for attaching the slide carriage means to the upright member; and, (d) positioning means for controllably positioning the slide carriage relative to the upright member.
Claim 4
Dependent Claim 38 words
The drill press of claim 1 wherein the overhead mount means includes means for allowing the upright member to be oriented in an attitude extending alongside selected portions of an overhead structure for storage of the drill press.
Claim 5
Dependent Claim 26 words
The drill press of claim 1 wherein the overhead mount means includes quick release disengageable parts for releasably securing the upright member to an overhead structure.
Claim 6
Dependent Claim 41 words
The drill press of claim 1 wherein the overhead mount means includes means for slidably mounting the upright member to an existing overhead structure, thereby allowing the upright member to be moved laterally along a selected portion of the overhead structure.
Claim 7
Dependent Claim 65 words
The drill press of claim 5 wherein the means for slidably mounting the upright member to the existing overhead structure includes: (a) at least one rail connected to a selected portion of the existing overhead structure; (b) means for slidably connecting the upright member to the rail; and, (c) means for releasably securing the upright member to selected locations along the length of the rail.
Claim 8
Dependent Claim 39 words
The drill press of claim 6 wherein the means for slidably connecting the upright member to the rail includes a collar journaling the rail and carrying locking means for fixing the relative positions of the collar and the rail.
Claim 9
Dependent Claim 30 words
The drill press of claim 6 wherein the means for slidably connecting the upright member to the rail includes disengageable parts for releasably securing the upright member to the rail.
