RAPPlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 497,498, dated May 16, 1893.

Application filed January 22, 1892. $erial No. 418,935. (No model.)

To all whom it may concern.-

Be it known that I, EUGENE L. HOWE, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented anew and useful Improvement in Rapping-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification,

material is fed to the boxes, adjustable hammers constructed andarranged to beat'upon the boxes so as to jar the same and to cause the settling of the packing around the-castings, a frame-work, and means by which the hammers are actuated. "These parts, when combined as shown, form what I believe to be the most desirable construction of my machine. It should be understood, however, that the parts may be modified in construction, and, within the scope of my broader claims, some may be omitted or supplied by other devices.

Referring now to the drawings, 2 represents the frame of the machine.

3 is the feed-hopper into which the packing material is charged, and from which it is delivered as desired in quantities regulated by means of a suitable valve or gate (not shown) situate at the lower end. Beneath the mouth of the hopper is a secondary frame 4, of suitable form, in which opposite hammer-levers 5 are pivoted at points 6, the shorter arms of the levers being connected by a bar 7, so that when the levers are oscillated they shall operate reciprocally in opposite directions to beat alternately upon the box.

To oscillate the levers I employ a reciprocatoi'y rod 8 set in suitable guides and actuated by a motor through any convenient transmitting mechanism (not shown). In order to provide for the easy connection of the hammer-levers with the rod 8 and their disconnection therefrom, I provide the rod with two collars 9, and the connecting bar 7 with a hook set pivotally thereon by means of a rotatory sleeve 11 from which it projects. When this hook is turned so as to engage the rod between the collars, the reciprocation of the rod will cause the reciprocation of the bar and theoscillation of the hammer levers to which it is connected, and when the hook is disengaged the motion of the rod will not affect the bar. not fixed to the connecting bar, but is set loosely so as to be capable of sliding thereon. On'both sides of it are springs 12 which bear against the sleeve and against collars 13, which are adj ustably fixed to the rod by set-screws 14. By reason of the presence of these springs, the reciprocation of the'rod is transmitted to the connecting bar not rigidly but yieldingly,

The sleeve of the hook is thus giving the hammers a freer and better action in their work of rapping the packingboxes hereinafterdescribcd. The box 15, in which the castings are packed, is set between the hammers, and preferably consists of three superposed separable parts I), c, and d, and in order that the hammers may be used to strike each of these parts,-the hammer-heads 16'are set on the levers so as to be movable longitudinally thereon, and are provided with pawls 17, by which they may be adjusted and held at notches e in dilferent positions, so as to be adapted to strike the several parts of the box.

The operation is as follows:-The bottom compartment (1 is placed upon its supporting plate 18 and the hammer-heads are moved down and secured at the lowest notches on the levers. A layer of packing material is then fed into the compartment d from the hopper, a layer of castings to be annealed is placed thereon; then more packing is introduced, and the ham mer-levers are caused to oscillate and to strike against oppositesides of the box, thereby jarring it and causing the packing material to settle closely around the castings. In this manner alternate layers of castings and packing are introduced until the compartment is full, the striking of the hammers being maintained. When this compartto be introduced into the heating furnace.

The advantages of the machine in respect of the great saving of labor which it eifects t and the rapidity and efficiency with which its Work is performed will be appreciated by those skilled in the art who are familiar with the laborious and expensive handwork here tofore required for this purpose. By reason of the fact that the hammers may be operated continuously during the feeding of the packinggwhich can be introduced ina thin regular streaxmthe packing can be settled and. brought into intimatecontaet with 1 every Part oi the surfaces of thecastings much more thoroughly than has been possible here-.

tofore. The result is that the articles are less apt-tobe distorted in form and are better annealed.

Changes in, the construction and arrange ment of the mechanism will suggest themselves. Thus,the hammers may be alteredin. form and mode of adjustment, mechanism other than levers. may be used to operat them, and in other respects the construction may be varied. The power used to drivethe machine may be steam power, han( i-power,

or derived from some other-suitable motor. Therefore, I do not limit myself strictly tothe described construction, unless. the same. is expressly included in the terms of the several claims. The machine may be used for any purpose (other than for rappingcastings) for. whiclrit is adapted.

I. claim as my invention- 1. A rapping-machine, having in combina tion with the machine-frame, hammers arranged to strike upon the sides of the packing-box, mechanism for actuating the same and means for feeding material into the box; substantially as described.

2. A rapping-machine, having in combination, with the machine frame, hammers adapted to strike alternately upon the packing-box, mechanism for actuating the same .and means for feeding material into the box; substantially as and for the purposes described.

3. A rapping-machine, having in combination, with the machine-frame hammers arranged to strike upon the sides of the packing-box, mechanism for actuating the same, ;and a feed-hopperabove the box support; substantially as and for the purposes described. 4.
