Abstract
Abstract A security mounting device for a chain saw is disclosed which consists of a base plate carrying a downwardly directed channel spaced above and at one end of the base plate. The channel is adapted to receive and embrace the operator's handle of a chain saw. A pair of transversely spaced plates are carried at the other end of the base plate and project upwardly therefrom and are adapted to receive therebetween the chain bar of the saw. Holes are provided in the upper ends of the spaced plates which receive a demountable pin, said pin, when in place, being adapted to confine the chain bar within the transversely spaced plates. Resilient means such as rubber-like pads may be carried by the base plate and the channel to flexibly engage the saw motor housing and operator handle, respectively. The pin may be provided with a hole to receive a conventional pad lock to prevent removal of the saw from the device. Means may be provided on the base plate to secure the plate to a supporting structure such as the bed of a pickup truck.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
171 words
In a security mounting device for a chain saw, said chain saw comprising a motor housing, an operator handle connected to and projecting rearwardly from the motor housing, a chain guide bar projecting forwardly from the motor housing, bolt and nut means on the side of the housing and adapted to connect the chain bar to the housing, the combination of a support member, connection means associated with the support member and adapted to connect the member to a supporting structure, an upwardly projecting element at one end of the support member, p1 channel means carried by the element in spaced relation to the support member and arranged to receive and embrace the operator handle, a pair of guide plates at the other end of the support member and projecting upwardly therefrom and arranged to receive the chain bar therebetween, pin means demountably arranged on the upper ends of the guide plates and adapted to engage the upper edge of the chain bar thereby confine the bar between the guide plates.
Claim 2
Dependent Claim
171 words
In a security mounting device for a chain saw, said chain saw comprising a motor housing, an operator handle connected to and projecting rearwardly from the motor housing, a chain guide bar projecting forwardly from the motor housing, bolt and nut means on the side of the housing and adapted to connect the chain bar to the housing, the combination of a support member, connection means associated with the support member and adapted to connect the member to a supporting structure, an upwardly projecting element at one end of the support member, p1 channel means carried by the element in spaced relation to the support member and arranged to receive and embrace the operator handle, a pair of guide plates at the other end of the support member and projecting upwardly therefrom and arranged to receive the chain bar therebetween, pin means demountably arranged on the upper ends of the guide plates and adapted to engage the upper edge of the chain bar thereby confine the bar between the guide plates.
Claim 3
Dependent Claim
59 words
A security mounting device for a chain saw according to claim 1; wherein one of the said plates is carried by the support member immediately adjacent the bolt and nut means preventing access to said bolt and nut means and thereby preventing disconnection of the chain bar from the motor housing when the saw is mounted in the device.
Claim 4
Dependent Claim
60 words
A security mounting device for a chain saw according to claim 2; and including resilient means carried by the support member and adapted to flexibly engage the lower surface of the motor housing to bias the chain saw upwardly and bring the operator handle and the chain bar in to firm engagement with the channel means and pin means, respectively.
Claim 5
Dependent Claim
28 words
A security mounting device for a chain saw according to claim 3; and including, other resilient means within the channel means to flexibly engage the embraced operator handle.
Claim 6
Dependent Claim
23 words
A security mounting device for a chain saw according to claim 1, wherein the supporting structure is the bed of a pickup truck.
