NATHANIEL M. JONES, OF BANGOR, AND LEONARD B. BRYANT, OF LINCOLN, MAINE.

Specification of Letters Patent.

Patented June 2, 1908.

Application filed July 23, 1907. Serial No. 385,154.

To all whom it may concern:

Be it known that we, NATHANIEL M.

'JONES and LEONARD B. BRYANT, of Bangor Log-Carriers-and Stakes Therefor, of which the following is a specification.

This invention relates to carriers for transporting logs and other elongated bodies of considerable bull: and weight, and may be embodied in a carrier adapted to be drawn by draft animals, or in a carrier, such as a platform car, adapted to run on rails.

The invention has for its object to provide a stake adapted to retain a load upon the carrier, and to be readily released from its operative position to release the load without being disconnected from the carrier, our invention being embodied in a reinforcing member adapted for attachment to the carrier body,

and provided with a dog-engaging shoulder, and a stake pivoted to said member, and provided'with a pivoted dog adapted to engage said shoulder, the arrangement being such that the stake is adapted to swing downwardly to an inoperative position below the carrier, and to swing upwardly to an operative position above the carrier, the dog and shoulder being so arranged that the dog when engaged with the shoulder acts as a strut to lock the stake in its operative position, and oppose outward movement of the stake, all as hereinafter more fully described.

Of the accompanying drawings, forminga part of this specification,Figure l represents a side elevation of a rocker adapted to be mounted on sleds or other supports, and forming part of a log-carrier, the said rocker being provided with stake-attachments, em-

bodying our invention, a portion of the rocker being shown in section. Fig. 2 represents an end elevation of the rocker and stake-attachment shown in Fig. 1. Figs. 3 and 4 represent perspective views showing the parts of the stake-attachment detached from each other and from the carrier.

The same letters of reference indicate the same parts in all the figures.

In the drawings, 12 represents a rocker which forms a part of an ordinary log-carrier, such as is used in logging operations, the rocker being composed of a stout beam adapted to be mounted upon sleds or trucks,

and constituting a part of a log-carrier, the

complete carrier comprising two similar rockers and their supports.

For convenience we hereinafter refer to the rocker 12 as a carrier, and it will be understood that this term is intended to include any support for a load of logs, such as the body of a fiat or platform car.

13 13 represent reinforcing members applied to the carrier 12, the said members being at opposite sides of the log-supporting portion of the carrier, and provided with downwardly projecting ears 14, which enter slots formed for their reception in the carrier. Between the ears 14, the member 13 is provided with a slot 15, the inner end 16 of which constitutes an abutment for a stake 17. The said stake is pivoted at 18 to ears 14 14, the ears arrangement being such that when the stake projects upwardly, as shown by full lines in Fig. 1, it will bear against the abutment 16, the latter preventing the stake from swinging inwardly beyond a substantially vertical position. The stake is adapted, however, to swing outwardly in the slot, and to depend vertically from the carrier, or to stand at any intermediate angle, for use as a skid, to assist in loading logs on to the carrier. The reinforcing member 13 is provided with a shoulder 19, which is opposed to the abutment 16 and is located at the outer end portion of the reinforcing member and outside, or at the-outer side of the stake. 20 represents a dog, which is pivoted at 21 to the stake, and projects outwardly from the stake and is adapted to engage the shoulder 19 when the stake comes to a bearing on the abutment 16, the location of the shoulder 19 outside the stake causing the dog to act as a strut to oppose outward movement of the stake under the outward pressure of the load against it. The engagement of the dog with the shoulder 19 therefore locks the stake against outward movement, the dog being held in engagement with the shoulder wholly by the outward pressure of the load against the stake. The reinforcing member, the stake and the dog are preferably composed of metal. The reinforcing member is securely attached to the carrier by bolts 25, aided by the engagement of the ears 14 with the slot formed for their reception in the carrier. The dog is provided with ears or wings 23, the lower ends or faces of which are above the shoulder-engaging end of the dog, and are separated from the reinforcing plate by a space adapted to receive a crowbar or other instrument, whereby the dog may be pried upwardly to disengage it from the shoulder 1-9. A very slight upward movement of the dog is suflicient for this purpose. The pressure of the load against the stake throws the latter outward when the dog is disengaged. Two wings 28 are referably provided so that two prying too s can be used simultaneously to raise the dog from engagement with the shoulder 19.

It will be seen that the dog 20 acting as a strut held by the load in engagement with the shoulder 19 located outside the stake is adapted to be held in its operative or looking position wholly by the pressure of the load against the stake, no additional or special dog locking or holding means being required. It will also be seen that the reinforcing member 13, made in a single part, furnishes a secure connection between the stake and the body of the carrier, and also provides for the secure engagement of the dog with the carrier to hold the stake in its operative position, the reinforcing member sustaining all the wear due to the swinging of the stake on its pivot, and to the engagement of the dog with the carrier. We do not limit ourselves to the employment of a reinforcing member made in one piece, which includes the bearings for the stake, as our invention may be embodied in any suitable structure, comprising a portable support having a stake abutment, and a dog-engaging shoulder opposed to said abutment and located outside the stake, in combination with a stake pivoted to the support, and adapted to bear against the abutment when in its operative position, and a dog pivoted to the stake, and adapted to en gage the said shoulder when the stake comes to a bearing on the abutment, the dog acting as a strut which is held in engagement with the shoulder wholly by the pressure of the load.

We claim 1. A stake attachment comprising a reinforcing member adapted for attachment to a supporting body, and provided with a stake abutment, and with a dog-engaging shoulder opposed to said abutment, and a stake pivoted to said member, and provided with a dog adapted to engage said shoulder, and hold the stake against the abutment.

2. A stake attachment comprising a reinforcing member adapted for attachment to a supporting body, and provided with a slot,

the inner end of which forms a stake abutment, depending ears at opposite sides of the slot, and a shoulder opposed to said stop, a

stake pivoted to said ears at a point below the plate, and a dog pivoted to the stake and adapted to engage said shoulder and hold the stake against the abutment;

3. A portable support having a stakeabutment, and a dog-engaging shoulder opposed to said abutment, a stake pivoted to the support, and adapted to bear against the abutment when in its operative position, ,and a dog pivoted to the stake and adapted to engage said shoulder when the stake comes to a bearing on the abutment.

4. A portable support having a dog-engaging shoulder, a stake pivoted to the support, and a dog pivoted to the stake, and adapted to engage the shoulder, said dog having a face,

separated from the support by a tool-receiving space, the shoulder being located at the outer side of the stake, so that the dog acts as a strut to oppose outward movement of the stake.

5. A portable support having a slot extending inwardly from its outer face, said slot being open both at the top and bottom of the support, a stake-abutment at the inner end of the slot, a dog-engaging should-er opposed to the abutment and located between the said abutment and outer face, a stake pivotally connected with the support within the slot, and adapted to bear on the abutment when in its operative position, and a dog pivoted to the stake, and adapted to engage the shoulder and hold the stake in its operative position, the stake being adapted to swing downwardly in the slot from said position.

6. A portable support having a dog-engaging shoulder at its outer end, a stake abutment at the inner side of said shoulder, a stake pivoted to the support at a point below the shoulder and abutment, and adapted to occupy a vertical position to support the load, and to be inclined downwardly and outwardly from the support to act as a skid, and a dog pivoted to the stake and adapted to engage the shoulder and hold the stake against the abutment, the dog being at the outer side of the stake when the latter is in its vertical position, and at the under side of the stake when the latter is inclined to act as a skid.

In testimony whereof we have affixed our signatures, in presence of two witnesses.
