JOHN THOMPSON GAR-DINER, 0F TYNDALL, MANITOBA, CANADA.
ATTACHMENT TO FLANEE-HEADS.
Specification of Letters Patent.
Application filed April 19, 1913. Serial No. 762,398.
To all whom it may concern Be it known that 1, JOHN THOMPSON-GAR- DINER, of the village of Tyndall, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Attachments to Planer-Heads, of which the following is the specification.
The invention relates to an attachment to planer heads and the objects of the invention is to provide a device whereby the tool carried by the planer head can be quickly and easily raised by the attendant by the simple manipulation of a lever and it consists essentially in a lever pivotally secured to the tool head and an arm pivotally secured to the tool and to the lever, the parts being arranged and constructed as hereinafter more particularly described.
Figure 1 represents a side view of the device applied on a planer head, Fig. 2 a front View and Fig. 3 an enlarged detailed side view of a portion of the lever and arm, certain parts being shown in vertical section to expose construction.
In the drawings like characters of reference indicate corresponding parts in each figure.
1 represents the beam of a planer carrylng the usual adjusting screws 2 and supporting the back plate 3 which carries slidably the head plate 4.
5 represents the head adjustably secured to the head plate and fitted with a pair of opposing lugs 6 and 7 supplied with a cross bolt 8 on which is mounted the tool holder 9.
10 represents a tool carried by the tool holder and fastened to the same by the set screws 11.
The above parts form no portion of my invention and accordingly their construction has not been entered into in detail.
My invention relates to a device for raising the toolholder and locking it in the raised position. At present there is nothing apparently supplied to accomplish this and the attendant usually swings the tool holder forward and places a block behind it, depending on the block to hold it. A considerable number of accidents have happened through the block slipping and the tool dropping and jamming the attendants fingers between the tool and the work. My device completely avoids this diihculty as once the tool is swung up by the attendant it cannot drop until he releases it.
12 is a lever fastened pivotally by a bolt 13 to the side of the head.
14 is an arm secured by a pivot bolt 15 to the lever. The other end of the arm is connected by a pivot pin 16 to lugs 16 secured to the back face of the tool holder, which it will be understood has the sides thereof extending beyond the sides of the head.
The arm is fitted with a projecting neck 17 supplied with an offset catch piece 18 arranged when the lever is thrown into the position shown in dotted outline in Fig. 1 to engage with the body of the lever and prevent further motion and also look the tool holder in the raised position until the lever is released by the attendant.
It will be noticed that the parts are so arranged that in the turned position of the lever the outer end of the arm is above the lever and with the natural tendency of the tool as operated upon by gravity is to swing the arm upwardly and to jam the catch piece more tightly against the body of the lever.
The pivot bolts 13 and 15 are of special construction. The bolt 13 is provided with a head piece 13 which but-ts against the head 5 when the screw is tightened up-and it is supplied with a shoulder 13 and a contracted extending threaded end 13 which receives a nut 13*.
The lever 12 is swung on the shoulder and the washer 19 is placed between the shoulder and the nut. The nut can accordingly be jammed down without tightening on the lever.
The bolt 15 has a body portion 15 which receives both the lever and the arm and it is supplied with an extending contracted threaded end 15 which receives a washer 20 and a nut 21.
When the nut is tightened up the washer jams against the shoulder formed by the contracted end 15 so that the lever and arm are free to turneasily on the bolt.
What I claim as my invention is:
1. The combination with a head and a tool holder pivotally secured to the head, of a normally upright lever having the lower end thereof pivotally secured to the head and an arm pivotally secured to the tool holder and to the lever above the pivot point of said lever a catch piece on said arm engageable with said lever, the connection between the lever and the arm being in the normal position of the lever in a higher Patented Feb. 17, 1914...
horizontal plane than the connection between the arm and the tool holder, as and for the purpose specified.
2. The combination with a pivoted tool holder having a pair of lugs on the rear face thereof, of a normally upright lever having the lower end thereof pivotally secured to the tool holder and the body portion thereof offset away from the tool holder and an arm pivotally secured to the lever above the pivot point of said lever and ,pivotally secured to the plugs by a pin, said arm having the end adjoining the lever supplied with. an offset catch piece engageable With the upper edge of the lever when said lever is 15 JOHN THOMPSON GARDINER.
In the presence of- G. S. ROXBURGH, S. GOULD.
Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Eateries. Washington, I). 0."
