SPECIFICATION forming part ef Lettere Patent Ne. 404,679, aetea June 4, 188e.
Application filed November 23, 1888. vSerial No. 291,715. (No model.)
T 0 all whom, it may concern,.-
Be it known that'I, THOMAS IV. BROOMELL, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Key-Seating Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.
My invention consists in the improvements in key-seating machines, hereinafter set forth and explained, and illustrated in the accompanying drawings, in which- Figure l is a side elevation of my improved machine, showing a Wheel-hub in place during the operation of key-seating the same.. Fig. 2 is a top or plan view of the same. Fig. 3 is a cross-section of my machine on the line ce in Fig. 2. Fig. 4. is a cross-section of the cutter-bar mechanism of my machine, showing it in place in a wheel-hub.
Like letters refer to like parts in all of the figures.
In the construction of my machine shown the frame thereof consists, essentially, of the ends A A', which are connected together by a base-bar B and the connecting-rods C C C2. In the ends A A of the frame are journaled screws D D', parallel to each other and under the connecting-rods C C', which pass through the end A, where they are geared together by spur-gears d, a bevel-gear a on the end of one of said screws intermeshing with a like gear a' on the upright shaft E, this shaft E being mounted in an arm E' on the end A of the frame. Around the upper end of the sleeve on the arm E', through which the upright shaft E passes, is a loose sleeve F, adapted to be moved around on its bearing and clamped in any desired position by means of the set-screw f. To the sleeve F is secured an outwardly and upwardly curved arm G, on the upper end of which is a sleeve g, which forms a bearing for the main driving-shaft II of the machine, which is geared to the upright shaft E by means of the mitergears I I', so that the motive power can be applied to the driving-pulley F on the main shaft H from any direction desired. In the base-bar I5 is cut a longitudinal slot J, which is so shaped as to form ways for the traverse of a carriage K therein. 3.) Through the upper portion of the carriage K is a transverse slot, in which a double nut L operates so as to alternately engage with one or the other of the screws D and D'. On the upper surface of the nut L, on one side thereof, is secured a longitudinal fiange b, and on the opposite side ltherefrom is secured a stud-pin Z, and on the central connecting-rod C2 is adjnstably secured a guide M, made, preferably, in sections M INI M2 M3, so that one or more sections can' be used at pleasure, as the length of the traverse of the nut L to and fro is regulated thereby, as hereinafter set forth.
On the side connecting-rods C and C' are adjustable clamps N and N', to which springs 0 and O' are secured, which serve to move the nut L, as hereinafter set fort-h. On the rods C and C' are also adjustable stops P and P', which operate to assist in throwing the nut L out of engagement with the screws in case of any defective operation of the springs O and O'. The operation of this nut L, it will be seen by referring to Fig. 2, is that the nut L having been thrown over by the spring O into contact with the screw D,it is carried along by the screw D, being held in contact therewith by the flange b thereon engaging with the guide M until it has traversed the length of the guide M, when the spring O, contacting therewith, throws the nut L over int-o contact with the screw D', which, running in the opposite direction, starts the nut back, the flange b now traversing on the opposite side of the' guide M, each change of the nut L being accomplished automatically by the contact of the nut L with the springs O and O. Incase,
(See Figs. l and .t
however, the springs O and O' fail to operate 95 the nut L, as described, as soon as the nut contacts with the guards P or'P itis thrown out of contact with the screws, so as to prevent injury to the mechanism. It will readily be seen from the foregoing description IOO that the carriage K is moved to and fro on its ways in the slot J by the operation of the transverse]y-sliding nut therein, operating alternately on the screws D and D', as described, so as to cause a continuous reciprocal longitudinal movement of the carriage K, for the purpose hereinafter set forth.
On the outer end of the carriage K are ears lo, through which a strong pintlej passes for connecting the reciprocating cutter-bar Q of the machine thereto. The cutter-bar mechanism of my machine is constructed of asemicircular outside shell R, having a circular collar R' on the inner end thereof, by means whereof it is secured to the end A' of the machine by short connecting-rods a2 and a3, so that the shell R is in line with the traverse of the carriage K.
lVithin the shell R is secured a second shell S, planed out on the inside, so as to form ways for the traverse of the cutter-bar Q. This shell S is also adjusted up and down in the shell R by means of adjusting-screws T and T', which pass through the outer s hellR into bearings in the inner shell S. The cutterbar Q is -provided with reverse cutters V V', and travels longitudinally in the ways in the inner shell S. On the inner end of the cutter-bar Q is an oblong eye Q', adapted to receive the pintlej, passing through the ears 7o on the carriage K, so that the motion of the carriage K, hereinafter described, is communicated to the cutter-bar Q, the slot Q adapting the bar Q and the shell S, within which it operates, to be adjusted up and down, as required, to complete a key-seat to the proper depth.
For securing the hub of a wheel to be keyseated in place against the collar R', a removable collar 2 is provided, which is adapted to be secured to the cutter-bar shell R by means of set-screws. I also provide semieircular bushings 3, of suitable size to fit the bore of the wheel-hub l to be key-seated, the inner faces of which bushings being of uniform size, so as to fit over the outside of the shell R.
In operation the collar 2 and supplemental collar et are removed from the shell R, the wheel-hub is then placed thereon, and suitable bushings 3 inserted, so as to center the hub thereon. The collar 2 is then secured in place and the supplemental collar 4 forced up against the end of the wheel-hub, so as to firmly clamp it against the collar R', thus bringing the cutter-bar mechanism in line with the hub-opening. The shell S, carrying the cutter-bar, is then set down until the cutter-bar in its forward and backward movement has cut the key-seat to a sufficient depth, when it is removed.
Having thus fully described my invention, so as to enable others to make and use the same, what I claim as new, and desire to secure by Letters Patent of the United States,
1. The combination, in a key-seating machine, of two parallel screws revolving in opposite directions, and a carriage adapted to be moved longitudinally by said screws with a nut operating in a transverse slot in said carriage, a guide-nut M, and cam mechanism secured to the machine-frame near each end of the nut-guide, adapted to engage with the nut as it leaves the end of said guide and automatically move the nut out of engagement with one of said screws and into engagementwith the other, substantially as and for the purpose set forth.
2. The combination, in a key-seating machine, of two parallel screws revolving in opposite directions, and a laterally-moving uut adapted to engage alternately with each of said screws, with an adjustable guide to retain the nut in contact with said screws, and springs adapted to move said nut out of contact with one of said screws after it has passed the guide and into contact with the other screw, substantially as and for the purpose set forth.
3. The combination, in a key-seating machine, of a reciprocating cutter-bar incloscd and traveling in an adjustable semieircular shell, with an outer semieircular shell inclosing said inner shell, and adjusting-screws for adjusting said inner shell, substantially as and for the purpose set forth.
t. The combination, in a key-seating machine, of the screws D and D', geared together so as to run in opposite directions, and a traveling carriage K, operating on ways parallel to said screws, with a reciprocating nut L, operating in a transverse slot in said carriage, and the sectional guide M, for retaining the nut in position dnrin g its traverse, substantif lly as and for the purpose set forth.
5. The combination, in a key-seating machine, of the frame-work A A' I5 and the screws D and D', geared together so as to run in opposite directions, with the reciprocating nut L, operating in the carriage K, between said screws, substantially as and for the purpose set forth.
6. The combination, in a key-seating machine, of the reciprocating nut L, operating between the screws D and D', and the adjustable guide M, with the springs O and O', for changing the position of the nut after it has passed the guide M, substantially as and for the purpose set forth.
In testimony whereof I affix my signature in presence of two witnesses.
