DROP-HAMMER.
SpecificationOfLettersIatent. Patented Sept. 3, 1918.
- Application filed March 28, 1917. Serial No. 158,062.
To all whom it may concern: 1
Be it known that I, VVHITNEY MERRILL, a citizen of the United States, and resident of the borough of Brooklyn, in the clty and State of New York, have invented a new and useful Improvement in Drop-Hammers, of which the following is a specification,
This invention relates to an improvement in-drop hammers, and more particularly to means for adjusting the guides or uprights which serve to direct the movement of the hammer, with the object in view of; provlding such an arrangement which is simple n construction, very durable and positive in action, easy to operate, and accessible.
Another object consists in providing certain improvements in the form, construction and arrangement of the parts'whereby the above named and further objects may be effectively attained. 1
A practical embodiment of my invention is represented in the accompanying draw ings in which,
Figure 1 represents a fragmentary side view showing the anvil, hammer, and guides.
Fig. 2 represents a fragmentary end view of the parts shown in Fig. 1.
Fig. 3' represents a fragmentary side view, partly broken away to show the arrangement of the adjusting mechanism in the anvil and one of the guides.
Fig. i represents a section taken in the plane of the line IVIV of Fig. 1, looking in the direction of the arrows.
Fig. 5 represents a top plan view of the anvil and adjusting mechanism, with the guides removed. 7
Fig. 6 represents an enlarged detail section showing one of the means for actuating the adjusting mechanism.
Fig. 7 represents an enlarged section of part of the means for actuating the adjust- :ing mechanism, taken at right angles to the section shown in Fig. 6, and
Fig. 8 represents a view similar to Fig.
7 but showing the arrangement for locking the'means for actuating the adjusting mechanism.
In drop hammers it has been found necessary to provide acertain amount of adjust ment for at least one of the guides in order to exactly register the hammer with the matrix carried by the anvil; and in order, further, to maintain exact alinement between the guides. Various means have been tried for this purpose, but they have all'been objectionable in that they were inaccessible, apt to break, lacking in durability, operative upon only one of the guides, or for other reasons. My invention is calculated to overcome these defects. Y
' Referring to the embodiment shown in the drawings, the anvil is denoted by 1, the hammer by 2, and the guides by 3, 4. Inasmuch as this invention has nothing to do with the form of lifting board or mechanism for'actuating the hammer, the same is not shown. v
The anvil is cut away centrally in the usual dove-tail formation. for receiving the matrix, and each of its upper side parts has a transversely extending groove 5, 6, which are fitted to receive tongues 7 that project downwardly from the bottoms'of the guides 3, 4. WVhile these tongues 7 are only shown in connection'with the guide 3, (see Fig. 3), it will be understood that the other guide 4 is similarly fashioned.
The upper side parts of the anvil 1, also have diagonally extending channels '8, 9, which are. calculated to receive similarly shaped portions 10, 11, of the adjusting bars. The channels 8, 9, and cooperating portions 10, 11, of the adjusting bars are rectangular in cross section. The said bars also comprise heavy splines 12, 13, which are formed integral with the-portions 10, 11, and lie above the latter. These splines- 12, 13, are fitted to have a tight sliding engagement with slots 14 cut in the bottoms of the guides 3, 4, intermediate the tongues 7. While only one slot 14; is shown, viz that formed inthe'guide 3, (see Fig.3), it is to be understood that the guide 4 is similarly provided.
The portions 10, 11, of the adjusting bars are screw-threaded at one end for engage ment with'the nuts 15 and 1 6; which nuts are rotatable in circular recesses 17, and 18. Eaclrofthese nuts is also provided with an annular series of sockets 19 and 20, fitted to. receive a spanner orspike for rotating the nuts in a well understood manner.
In order to prevent the nuts 15 and 16 from moving longitudinally in the recesses 17 and 18, and to provide outer bearing shoulders for the said nuts, I arrange coladjusting bars, and which are fixed against longitudinal and rotary movement in the recesses 17 and 18, respectively, by means of cap screws 23 and 2%.
Each of the nuts 15 and 16 also has a second annular series of sockets which are fitted to receive lugs 26 carried by locking springs 27 secured to the anvil by means of cap screws 28. This arrangement serves to lock the nuts against rotary movement.
In operation, when the parts are arranged and assembled as above described, it is simply necessary for the operator to lift one of the springs 27 so that its lug 26 no longer engages the socket in the adjacentnut, and then, by rotating the nut, the adjusting bar is caused to move longitudinally. Owing to the fact that the bars are arranged to slide in angularly disposed grooves, as already mentioned, this longitudinal movement will not only slide the spline 12 or 13 in its slot ll, but it will cause the said spline 12 or 13 to move laterally with respect to the anvil, that is, longitudinally with respect to either of the grooves 5 or 6. This last named movement of the spline which being actuated, will impart movement in a similar direction to the guide 8 or 4., which it engages, and will thus cause the guide to move toward or away from the center of the anvil. Both guides may be similarly adjusted. \Vhen the proper adj ustment has been made, the locking devices 26. 27, may be utilized for preventing "further movement of the adjusting bars, and the guides 3. I, may be additionally secured in the desired adjustment by means of bolts 29, 29 and 30, 30. Slots 31., 31 and 32, 32, are provided in the anvil, through which the bolts 29. 29, and S0, 30 pass. so as to permit the said bolts to move with the guides 3, at, as the latter are adjusted.
It will be understood that various changes may be resorted to in the form, construction and arrangement of the several parts without departing from the spirit and scope of my invention, and hence I do not intend to be limited to the details herein shown and described, except as they are specifically in cluded in the claims.
IVhat I claim is:
1. In a drop hammer, an anvil, a hammer guide, and means for laterally adjusting the one with respect to the other, said means comprising a bar engaging the one at an acute angle to the line of adjustment and engaging the other at an angle to its engagement with the one, said engagements permitting longitudinal but preventing lateral movement of the bar, and means for imparting longitudinal movement to the bar.
2. In a drop hammer, an anvil, a hammer guide, and means for laterally adjusting the guide with respect to the anvil, said means comprising a bar engaging the anvil at an acute angle to the line of adjustmentand engaging the guide at an angle to its engagement with the anvil, said engage ments permitting longitudinal but prevent-- ing lateral movement of the bar, and means for imparting longitudinal movement to the bar.
3. In a drop hammer, an anvil, a hammer guide, and means for laterally adjusting the one with respect to the other, said means comprising a bar engaging the one at an acute angle to the line of adjustment and en gaging the other at an angle to its engagement with the one, said engagements permitting longitudinal but preventing lateral movement of the bar, means for imparting longitudinal movement to the bar, and means for locking the bar against longitudinal movement.
1. In a drop hammer, an anvil, a hammer guide, and means for laterally adjusting the one with respect to the other. said means comprising a groove fashioned in the one at an acute angle to the line of adjustment. a slot fashioned in the other at an angle to the said groove in the one, an adjusting bar having two parts, one part fitted to slide in the saidgroove and the other part fitted to slide in the said slot, and means for imparting a sliding movement to the bar in the said groove and slot.
5. In a drop hammer, an anvila hammer guide, and means for laterally adjusting the guide with respect to the anvil, said means comprising a groove fashioned in the anvil at an acute angle to the line of adjustment, a slot fashioned in the guide at an angle to the groove in the anvil, an adjusting bar having two parts. one part fitted to slide in the said groove and the other part fitted to slide in the said slot, and means for imparting a. sliding movement to the bar in the said groove and slot.
In testimony, that I claim the foregoing as my invention. I have signed my name this 22 day of March, 1917.
