Abstract
Abstract A hanger-type ceiling-attachable support has a shallow pan engageable against a ceiling surface. A bellows or a piston-in-cylinder type of reservoir for liquid cement underlies the pan, and when it is compressed upwardly by a post depending from the reservoir, injects cement into the pan and against the ceiling surface. The depending post serves both (1) as an attachment device for a plural-section manipulating pole and (2) as a fastener for a suspension wire. The pole sections are inter-nestable for storing and carrying. A horizontally adjustable measuring rod aids in accurately spacing being-installed supports from previously installed ones.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
110 words
A ceiling-attachable hanger-type support comprising: a horizontally disposable rigid circular plate-like element having at least one aperture located medially thereof, a cup-like member underlying the medial portion of said plate-like element and defining therewith a marginally sealed chamber, a short rigid post-like hanger-part depending axially from said cup-like member, and an initially liquid quickly-setting cement in said chamber, said chamber being so volume-variably constructed that an upward force exerted against said hanger-part will cause said cement to flow through said aperture and between said plate-like element and a ceiling surface juxtaposed thereto, and said cement being sufficiently viscous initially to hold said support in desired position while said cement hardens.
Claim 2
Dependent Claim
110 words
A ceiling-attachable hanger-type support comprising: a horizontally disposable rigid circular plate-like element having at least one aperture located medially thereof, a cup-like member underlying the medial portion of said plate-like element and defining therewith a marginally sealed chamber, a short rigid post-like hanger-part depending axially from said cup-like member, and an initially liquid quickly-setting cement in said chamber, said chamber being so volume-variably constructed that an upward force exerted against said hanger-part will cause said cement to flow through said aperture and between said plate-like element and a ceiling surface juxtaposed thereto, and said cement being sufficiently viscous initially to hold said support in desired position while said cement hardens.
Claim 3
Dependent Claim
22 words
A support according to claim 1 and additionally comprising means on said plate-like element for spacing it slightly from said ceiling surface.
Claim 4
Dependent Claim
18 words
A support according to claim 2 wherein said spacing means is an upturned rim on said plate-like element.
Claim 5
Dependent Claim
21 words
A support according to claim 2 wherein said spacing means is a plurality of widely spaced protuberances on said plate-like element.
Claim 6
Dependent Claim
33 words
A support according to claim 1 and additionally comprising a manipulating pole therefor having means on its upper end for quickly and easily detachably engaging said post-like hanger-part to mount said support thereon.
Claim 7
Dependent Claim
22 words
A combination according to claim 5 wherein said pole comprises at least two easily detachably interconnected sections constructed for non-use nested storage.
Claim 8
Dependent Claim
26 words
A combination according to claim 6 and additionally comprising a measuring rod horizontally adjustably connectable to said pole for gauging distances between attached and being-attached supports.
Claim 9
Dependent Claim
39 words
A support according to claim 1 wherein said cup-like member comprises a cylinder and a piston therein and said piston includes air-admitting check-valve-like means for allowing said piston to return quickly to its initial position after dispensing said cement.
Claim 10
Dependent Claim
34 words
A support according to claim 1 wherein said cup-like member comprises a disk underlying said plate-like element and a flexible sleeve-like means peripherally sealing the cement-storing chamber between said disk and said plate-like element.
Claim 11
Dependent Claim
41 words
A support according to claim 9 wherein said aperture in said plate-like element is initially sealed by a small disk seated on a countersunk seat around said aperture and is connected to said depending post-like hanger-part by a slender co-axial rod.
