STEAM-HAMMER GUIDE.
Specification of Letters Patent. Patented June 21, 1921.
Application filed July 7, 1920. Serial No. 394,499.
My invention relates to certain improve` ments in means for adjusting the guides of steam hammers.
The object of the invention is to provide adjusting means in which an extended bearing is obtained and also to provide an adjusting means operable from each end of the o'uides so that accurate adjustments can `be made.
In the accompanying drawings:
Figure 1 is a view in elevation of a steam hammer with a pait in section to illustrate my invention; and
Fig. 2 is a detached perspective view showing the guide and two wedges.
1 is the base of a steam hammer on which is mounted the standards 2 carrying the overhead structure 3 including the cylinder 4. 5 is the sliding hammerk head and 6 is the plunger rod connected to the head and to a piston in the cylinder' 4. 7- 7 are guides for' Vthe head.
These guides are pivotally connected at 8 to a bolt 9 which passes through the standards 2. A spring 10 is located on this bolt between the nut 11 and the frame so that the guide is yieldingly supported. The guide is held against longitudinal movement by the ends of the recess in the standards 2 in which each guide is mounted. The face of the guide has two V-shaped projec- .tions 12, Fig. 2, which enter grooves in the hammer head 5, in the present instance, although the shape of these connections between the guides and the hammer head may be varied without departing from the essential features et the invention.
The back of each guide 7 is beveled, one end being beveled in one direction and the opposite end'being beveled in the other direction. Back of these beveled surfaces is a straight bearing-surface 14 on the trame.
15 is a vertical wedge located between the bearing surface 14 and the beveled surface 13 at the upper end of the guide 7. This wedge has a threaded stem 16 on which are two nuts 17V and 18, which are located in a recess in the frame so that, on backing otf one nut and turning the other in the opposite direction, the wedge can be driven between the two surfaces 13 and 14 so as to project that portionot the guide 7,
15a is the lower wedge made similar to the wedge l5 and has a stem 16011 which are nuts 17a and 18a.. The lower wedge can be adjusted in the same manner as the upper wedge. When the two wedges are adjusted together, then the entire guide 7 is moved toward the center of the hammer, the spring 10 yielding suiliciently for this purpose.
.When it is desired to move one end of the guide a greater distance than the other to take up the wear, only one wedge may be moved forward and, it necessary, the other can be retracted.
In some instances, where a steam hammer is used for certain classes of work, and where the work is being hammered oit center, then one side ot the hammer guides is liable to wear away faster than the other side. By constructing the guide-adjusting means in the manner set forth, the guides can be readily adjusted to take up the wear. A s the wedges are of considerable length, they have full bearing on the backs of the guides, making a substantial support for the guides. i
I claim:
l. The combination in a steam hammer, ot' a standard; a guide pivotally mounted on the standard; a hammer head; means for reciprocating the head; a wedge located back of each end of a guide; and vmeans for adjusting the wedges.
2. The combination in a steam hammer, of two standards spaced apart; a hammer head located between the standards; means end of each guide and the bearing tace, eachV wedge having a stem; and nuts on each stem for longitudinally adjusting the wedges.
3. rlhe combination in a steam hammer,
` of two standards spaced apart, each standard having a longitudinal recess; a hammer head; pivoted guides tor thc head located in the recesses iii the standard; a longitudinal wedge between each end of each guide; a bearingface in the recess; and means for adjusting the wedges.
