Abstract
Abstract A wheeled platform provides a storage space for logs below an elevated track supported on standards rising from the platform. A trolley device movable along the track supports an easily adjustable log gripping and release device which is utilized to place logs in a fireplace or in the fire box of a stove or furnace. The user of the crane need not place the logs by hand, thus avoiding the possibility of being burned.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
106 words
A crane for handling fire logs comprising a wheeled support, a substantially horizontal track on said support, a log grapple having relatively movable log engaging grapple jaws and means for releasably locking said jaws in selected relative positions, and a flexible suspension means for said grapple on said track and movable freely with the grapple in opposite directions on said track, said log grapple being a manually operated grapple in which said jaws are relatively movable on a linear path, and said means for releasably locking said jaws comprising a spring-biased manually released friction locking device for one jaw and having engagement with the other jaw.
Claim 2
Dependent Claim
106 words
A crane for handling fire logs comprising a wheeled support, a substantially horizontal track on said support, a log grapple having relatively movable log engaging grapple jaws and means for releasably locking said jaws in selected relative positions, and a flexible suspension means for said grapple on said track and movable freely with the grapple in opposite directions on said track, said log grapple being a manually operated grapple in which said jaws are relatively movable on a linear path, and said means for releasably locking said jaws comprising a spring-biased manually released friction locking device for one jaw and having engagement with the other jaw.
Claim 3
Dependent Claim
42 words
A crane for handling fire logs as defined in claim 1, and said jaws having coaxial linear telescoping members each having a hand grip whereby relative movement of the jaws can be achieved when said locking device is in a release position.
Claim 4
Dependent Claim
112 words
A crane for handling fire logs as defined in claim 1, and said friction locking device comprising stacked locking washers including a trigger extension on at least one washer, coaxial telescoping members carrying said jaws in opposed relationship, said telescoping members having hand grips disposed substantially at right angles whereby the members and said jaws may be readily adjusted manually, and said locking washers embracing the innermost of said telescoping members to frictionally and releasably lock the latter relative to the outermost of said telescoping members, said trigger extension disposed near one of said hand grips whereby its operation can be accomplished by a finger of the hand gripping such hand grip.
Claim 5
Dependent Claim
34 words
A crane for handling fire logs as defined in claim 1, and an auxiliary positive locking device on the grapple to prevent relative movement of said jaws during periods of non-use of the crane.
