ROBERT J. TROEGER, OF LOS ANGELES, CAIZIFGRNIA.
SADDLE FGR PNEUMATIC HAMIVIEHS.
Specification of Letters Patent.
Patented Feb. a, 1919.
Application filed April :22, 1918. Serial No. 230,068.-
To all whom it may concern.-
Be it known that I, ROBERT a citizen of the United States, Los Angeles, in the county of and State of California, have invented new and: useful Improvements in Saddles for Pneumatic AI ammers, of which the following is a specification.
My object is to make a supplementary handle or saddle for attachment to pneumatic hammers and consists of the novel features herein shown, described and claimed.
Figure 1 is a side elevationof an ordinary pneumatic hammer provided with a supplementary handle or saddle embodying the principles of my invention.
Fig. 2 is an enlarged perspective detail of the attachment removed from the hammer.
n ordinary pneumatic hammer. has a barrel 1, a head 2, a return bend 3 extend backwardly and downwardly fromthe head 2, and a grip or handle t 1 extending downwardly from the rear end of the return bend 3. An air hose 5 is connected to the lower end of the handle a and an air valve lever 6 extends upwardly in the handle a.
The details of my supplementary handle or saddle 7 are as follows:
heavy metal strap is bent to form a curved supporting bar 8, an arm. 9 extend ing downwardly and forwardly from the lower end of the bar 8 and having a hose opening 10, an arm 11 extending upwardly and forwardly from the lower forward end of the arm 9, an arm 12 extending upwardly from the upper forward end of the arm 11 and having a curved upper end 13, an arm 14 extending upwardly and forwardly from the upper end of the supporting bar 8, and an arm 15 extending forwardly and downwardly from the upper end of the arm 14.
A hearing plate 16 is forged upon the forward end of the arm 15 and has a seat 17 in its lower face. The frame thus formed is placed in position with the arm 12 fitting against the rear face of the head 2, the curved portion 13 fitting the curved face of the return bend 3, the forward end J. Tnonenn, residing at Los Angeles of the arm 15 fitting the forward face of the return bend 3 and the seat 1'? fitting the upper face of the head 2. A U-holt l8 encircles the head 2 and extends upwardly through the bearing plate 16, and nuts 19 are applied to the upper ends of the U-bolt to clamp the plate rigidly upon the head 2. A U-bolt 20 is inserted upwardly, straddie of the curved port-ion 13 and'straddle of the return bend 3, a clamping plate :21 is placed crosswise of the arm 15 with the ends of the U-l olt extending through. the ends of the clamping plate 21 and nuts 22 are applied to the U-bolt so as to clamp the curved portion 13 rigidly against the re turn bend and clamp the forward endof the arm 15 rigidly against tl e other side of the return bond 3. The hose 5 extends through the opening 10. A section 23 of heavy rubber hose is placed against the outer face of the supporting bar 8 and held in place by winding with heavy tape 24.
In using a pneumatic hammer in shipbuilding-and the like it frequently happens that the hammer must be pointed upwardly all day long and it becomes a hard matter to support the hammer and press it against the work. By the use of my saddle attach.-
ment the operator may place the cushion upon his shoulder or upon his arm or knee and thus support the hammer with more ease. The cushion 23 serves as a shock absorber for the supporting'bar 8.
I have applied my saddle to a well known make of pneumatic hammer as shown in the drawings, but it will be imderstood that my saddle may be applied to any of pneumatic hammer,
arious changes may he made without departing from the spirit of my invention as claimed.
I claim:
1. A saddle for pneumatic hammers comprising, a heavy metal strap bent to form a supporting har, an arm extending downwardly and forwardly from the lower-end of the supporting bar and having a hose opening, a second arm ext-ending upwardly and forwardly from the forward end of the first arm, a third arm extending upwardly from the upper forward end of the second arm and having a curved upper end, a fourth arm extending upwardly and forwardly from the upper end of the supporting bar, and a fifth arm extending forwardly and downwardly from the pper end of the fourth arm; a bearing plate forged upon the forward end of the fifth arm and. having a seat in its lower face; the third arm. being adapted to fit against the rear face of a pneumatic hammer head pris ng,
lid
and the bearing plate being adapted to fit the upper faceof the pneumatic hammer head; a U-bolt adapted to encircle the hamrner head and engage the bearing plate; and a second U-bolt adapted to engage the curved upper end of the third arm and straddle the return bend of the hammer and the forward end, of the fifth arm; and a clamping plate fitting across the forward end of the fifth arm to recei e the second 2.- A saddle for pneumatic hammers "x9111- asupporting bar, an arm extending downwardly and forwardly lower end of the supporting bar and having a hose opening, a second arm extending upwardly and forwardly from the forward end of the fir t arm, a third arm extending upwardly from the upper forward end of the second aim and adapted to (it the rear from the face of a pneumatic hammer head, afourth arm extending upwardly and forwardly from the upper end of the supporting bar, a fifth arm extending forwardly and downwardly arm, a bearing extending forwardly from the fifth arm and adapted to fit the upper face of the pneumatic hammer head, a U- bolt adapted to encircle the hammer head and engage tha'bearing, a second U-holt tapte'd to engage the upper end of the third arm and straddle the return bend of the hammer head and the forward end of the fifth arm, and means for securing the second U-bolt to clamp the upper end of the third arm and the forward end of the fifth arm to the hammer head.
In testimony whereof I have signed my name to this specification.
