4 Claims.
lhis invention relates to new and useful improvements in pattern lathes and the primary object of the present invention is to provide a pattern lathe including a horizontally and Vertically movable carriage supporting a power driven shaft having a guide element and a cutter element secured thereto that will respectively engage a form and a piece of work to cut the work to the contour of the form upon which the guide element rides.
Another important object of the present invention is to provide a pattern lathe of the afore mentioned character involving a power driven shaft connected to the carriage and novel and improved means actuated by the carriage for reversing the rotation of the shaft.
A further object of the present invention is to provide a pattern lathe wherein the carriage is supported upon a vertically slidable frame that will move upwardly and downwardly as the guide element rides upon the irregular upper edge of a form so that a cutter element supported adjacent the guide will cut a work piece similar to the form upon which the guide element rides.
A still further aim of the present invention is to provide a patern lathe of the aforementioned character that is simple and practical in construction, strong and reliable in use, efficient and durable in operation, small and compact in structure, convenient to initiate the cutting operation, inexpensive to manufacture, and otherwise well adapted for the purposes for which the same in intended.
Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure l is a perspective view of the present invention; 7
Figure 2 is a front elevational view of Figure l Figure 3 is an end view of Figure 2;
Figure 4 is a vertical sectional view taken substantially on the plane of section line 4-4 of Figure 2;
Figure 5 is an enlarged detail sectional view taken substantially on the plane of section line 55 of Figure 1;
Figure 6 is an enlarged detail sectional view taken substantially on the plane of section line 6-45 of Figure 1; and
Figure 7 is a viewof the circuit diagram used .in the present invention.
Referring now to the drawings in detail, where- 2 in for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral It] represents an elongated support or table structure having pairs of uprights or posts 12 and I4 suitably secured thereto.
An elongated, open, substantially rectangular guide frame it extends horizontally over the support Ill. Sleeves it are slidably received on the uprights l2 and fixedly support horizontal arms 20 that are formed with apertures accommodating the ends of a transverse shaft 22 fixed under one end portion of the frame I6. J v
A pair of sleeves are. also slidably received on the uprights M. The sleeves 24 are provided with horizontally extending socket portions 26 that receive a pair of'armsZB extending longitudinally from the end of frame It remote from uprights l2. A plate 30 is slidably received on the uprights [4 below the sleeves24 and is centrally swiveled to the upper end ofa vertical screw 32 that is receivably engaged in an aperj ture 3:! in the support, whereby the plate 30 may be selectively raised and lowered to limit down} ward vertical sliding movement orueeves 24 on the uprights M. The frame It is mounted in this manner to allow free vertical movement of the frame is with respect to the support In.
Collars 36 having self-contained set screws 38 are vertically adjustably received on the uprights l4 and constitute abutments for coil springs 40 disposed about the uprights and biased against the upper ends of sleeves 24 to cushion and yield ingly restrict upward movement of sleeves 24 on the uprights.
The undercut forward and rear edges of a carriage 42 are slidably received upon the upper face of the frame It and the depending vertical walls of the undercut forward and rear edges rideagainst the longitudinal edges of, the opening in the frame to guide the longitudinal sliding movement of the carriage on the frame.
A horizontally disposed power driven shaft 44 is rotatably supported in suitable bearings 45 on the undersurface of the carriage 42. Shaft 44 extends transversely and forwardly and rearwardly of the frame I6 and its end portions carry guide elements or rollers 46 and a cutter element 48. The rear end of shaft 44 supports a pulley 59 that is connected to a pulley 52 on the armature shaft 54 of a motor 56 supported on the carriage 42 by an endless belt 58. a
Pairs of vertical guides 60, 6] and 62 are se cured to and extend upwardly from the support It). Holding members or horizontal boards 84;
65 and 66 are vertically slidably received on the guides 60, BI and 62, respectively. Upper collars 68, 69 and I having self-contained set screws are slidably adjustably received on the guides 60, 6| and 62 and limit upward movement of the members 64, 65 and 66. Lower collars 12 having self-contained set screws are slidably adjustably received on the guides 60 and 61 and retain the members 64 and 65 raised, and in conjunction with the collars 68 and 68 retain the members 64 and 65 vertically adjusted and hold members 64 and 65 against accidental sliding movement. The holding members 64 and 65 are mounted for adjustment in a vertical direction so as to be capable of receiving patterns of various depths. The member 66 is vertically adjustable so as to receive work of various depths corresponding to the patterns received on members 64 and 65.
A horizontal rock shaft I4 is supported in bearings I6 projecting forwardly from support I0. Arms 78 are suitably removably secured to the shaft I4 and these arms, I8 are connected to member 66 by pitmans 60. A hand lever 82 secured to the shaft 14 permits manual rotation of shaft I4 for selectively raising or lowering the member 66. Thus, member 66 can be raised or lowered in order to position the work into or out of engagement with the cutter. When the work is applied to member 66, the member 66 is in a lowered position and then the member 66 is raised to place the work into engagement with the cutter. After the work has been shaped, then the member 66 is lowered so that the work may be removed from the member 66.
One end of member 66 is formed with an opening 84 in which a coil spring 86 is retained. Spring 86 is biased against the shank 68 of a movable retainer block or abutment 90 slidable upon the upper face of member 66 (Figure The other end of member 66 is provided with a plurality of longitudinally spaced apertures 92 for selectively receiving the depending pin 94 of an upper retainer block or abutment 96 that coacts with block 90 in gripping the ends of a work piece W.
similar forms F are suitably removably secured to the members 64 and 65 in parallel relation to the work piece W and underlie the roller 46. Cutter element 48 underlies the work piece W and is spaced forwardly of the guide roller 46.
A pair of horizontally disposed spaced parallel arms 98 extend longitudinally from the end of the frame engaged with sleeves I8 and terminate in transverse registering eyes I00 that receive trunnions I02 projecting laterally from the central portion of a vertically swingable member or mounting plate I04. Motors I06 and I08, preferably of the electric type, are supported on the ends of member I04 and their drive shafts carry pulleys I I0 and H2 that are connected to spaced grooves in a pulley member II4 on one end of a screw threaded rod I I6 by belts I I6 and I20.
Rod II6 extends longitudinally of the frame I6 and its smooth surfaced end portions are journaled in bearings I22 on the undersurface of frame I0. Rod II6 extends through threaded apertures in ears I24 formed on the carriage 42, so that as the rod H6 is rotated in one direction the carriage will move from left to right, whereas rotation of the rod H6 in an opposite direction will move the carriage from right to left.
A solenoid I26 is held on one of the arms 98 and its operating core is pivotally attached to 9. lug I28 fixed to one of the trunnions I02. A spring I30 terminally attached to the member I04 and the arm 98 supporting the solenoid and the spring I30 normally retains the member I04 vertical when the solenoid I26 is not energized.
A single through switch I32 is supported on one end of frame I6 and a second single throw switch I34 is also supported on the other end of the frame I6. The switches I32 and I34 are operatively connected to the solenoid to selectively make and break an electric circuit to the solenoid. Additional switches I36 and I38 are connected to the circuits for the motors 56 and I06, I08, whereby the motor may be actuated or deactuated.
The drive shafts of motors I06 and I08 rotate in relatively opposite directions as indicated by arrows in Figure l and the belt H8 of motor I06 is tensioned against pulley member H4 and belt I20 is loose on pulley member I I4 when the member I04 is vertically disposed. However, when solenoid I26 is energized, the member I04 will be moved to a vertically inclined position tensioning belt I20 and loosening belt H8 in order to reverse the direction of rotation of rod I 6.
In practical use of the present invention, the carriage 42 is disposed at the right end of the frame I6 and the member I04 is vertically disposed to move the carriage leftward by rotating rod I I6. As the carriage moves leftward, rollers 46 ride upon the shaped upper edges of forms F and raise and lower the frame I6 and carriage 42 so that cutter element 48 will cut the work W to the same contour as form F.
When carriage 42 engages switch I32, the solenoid I I4 will be actuated to swing support I04 to avertically inclined position, thereby reversing shaft H6 in the manner previously described.
Work piece W may be lowered and removed by rotating shaft 14 and a new work piece placed on member 66 and raised to permit cutting of the same as the carriage is moved to the right.
