SPECIFICATION forming part of Letters Patent No. 772,433,
dated October 18, 1904.
Application filed September 12, 1903; Serial No. 172,880. (No model.)
To all whom it may concern.-
Be'it known that I, CHARLES E. SANDsTRoM,
a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Picture-Frame-Puttying Machines, &c., of which the following is a specification.
' This invention relates to machines for -put.
tying and decorating picture-frames and simi lar articles. I
The invention comprl1ses,1n general terms,
a reciprocating bed designed to support the picture-frame or other article tobe decorated and move the same under a roll to which is secured an embossing-die for impartlng the desired design'to'the putty, suitably appliedto the frame. To'avoid changing the die in operating on frames of different lengths, I preferably providemeans whereby the same die may be employed within certain limits for frames of varying sizes, and this is accomplished by. mechanism for drawing out the design to the extent necessary. To accomplish this result, provision is made for changing the relative speeds of the reciprocating bed and the embossing-die. embodiment of the invention herein set forth the desired end is attained by providing means for changing the speed of the roller, which under normal conditions moves at the same speed as the reciprocating bed during its movement,so that while the speed of the framecarried by the reciprocating bed is constant and uniform-the movement of the dieroll is retarded or made to lag behind the frame at a certain period or point in its rotation, to the end that the design is drawn out In the.
.machine, as at 18.
'scription and particularly'designated in the appended claims.
In the drawings, Figure 1 is a sectional elevation on the line w m of Fig. .7 of a pictureframe puttying and decorating machine con structed in accordance with my invention. Fig. 2. is a plan of atable designed to be se cured tothe reciprocating .bed and showing a picture-frame mounted thereon and means for securing the same in place. Fig. 3 is a section on the line y 3/ of Fig. 1. Fig. 4 is a side elevation of the machine viewed from the side opposite to that seen in Fig.1 and showing a feeding 'device'for supplying the putty to the frame. Fig. 5 is a detail of the embossingdie and the rollupon which the die is secured,
together with a portionof the frame-supporting table, and showing a different manner of holding the frame. Fig. 6 is a detail of the lever and sliding rod for shifting one of the driving-belts. Fig. 7 is a sectional elevation of one side of the machine, taken on the line e z of Fig. 1. Fig. 8 is aside elevation of the mechanism for varying the speed of the die-- roll. Fig. 9 is a side elevation of the slideblock and slide for regulating the variation in speed; and Fig. 10 is an edge view of-the same, showing in section the stationary gear em- .ployed therewith. V
The machine may be supported upon any suitable frame, such as that shown in the drawings, and consisting of the side rails 10,
supported by legs 11, connectedbycross bars or braces 12. Secured to the inner faces of the rails 10 or cast integral therewithv are tracks 13, one of which is shown in Fig. -7, and reciprocating on and partially supportedby such tracks at its side edges is a bed 14:. This bed is provided on its under face,adja cent theside edges thereof, with' racle'bars 15, with which mesh, so as to reciprocate the bed 14:, pinions 16, fixed on a horizontal shaft 17, journaled on the supporting-frame of the The shaft 1-7 has fixed thereon between the pinions 16 a roller 19, which assists the track in supporting the reciprocating bed, which bed is preferably pro vided on its under face with longitudinal ribs 20, resting and passing over the roller 19 I during the recipocation of the bed, as shown I oo in Fig. 5. One end of the shaft 17, projecting beyond the side of the frame, has secured thereon a large gear 21, to which motion is communicated by a pinion 22, meshing therewith and fixed on the adjacent end of the driving-shaft 23, journaled in the sides of the supporting-frame, as at 24, and extending parallel with the shaft 17. The end of the shaft 23 opposite the pinion 22 is extended beyond the side of the frame and has fixed thereon a driving-pulley 25, to which motion is communicated by a pair of belts 26 and 27, driven from any suitable source of power and which are designed to be moved onto the said pulley in alternation, and in order to reverse the movement of the shaft so as to impart a reciprocating movement to the bed 14 one of such belts is intended to be crossed. The belts 26 and 27 normally run over a pair of idle pulleys 28 and 29, journaled on the drive-shaft 23, and are shifted onto and off the active pulley by means of belt-shifters 30 and 31, hereinafter to be more fully described. The extended end of the shaft 23 may be journaled in a standard 32, located beyond the side of the machine, as shown in Fig. 7 in order to properly support the same.
Mounted on each of the side rails 10 and extending above the roller 19 is a vertical standard or support 33, and carried by these standards is a roll 34L, designed to have attached thereto the embossing-die 35, as shown in Fig. 5. In theconstruction illustrated the roll 34 comprises a series of disks or drums 36, fixed on a shaft 37, which is located directly over and parallel with the roller 19 and journaled in bearings carried by the standards v33. The disks 36 are spaced apart a slight distance in any suitable manner, as by means of the extended hubs 39 thereof.
The embossing or decorating die is shown in Fig. 5 and is of the required shape to impress the design thereof on the putty laid on the frame around the opening thereof or on the surface of other articles to be decorated. The die may be made of wood or cast from metal or a suitable composition and is curved to conform to the roll and may be fastened to the roll in any suitable manner and by any preferred means. In the construction illustrated the die-plate is provided with apertures near each edge thereof, and through these apertures are passed cap-screws 1O, entering between the disks 36, which are spaced apart for this purpose and engage threaded apertures in strips or blocks 41, located on the inner face of the rims of the disks. \Vhen the screws are tightened up, the die is rigidly clamped on the roll and between the screwheads and the strips 41. These strips are not secured to the disks, but are designed to be adjusted around the inner face of the diskrims. With the construction shown a die of any desired size up to the length and circumference of the roll may be employed.
Means are preferably, though not necessarily, provided for varying the d istancc between the reciprocating bed and the die-roll 34 in order to adapt the machine to frames or other articles of different thicknesses, and this end maybe attained by making the bearings in which the shaft 37 turns vertically :uljustable, as shown. In the construction illustrated the standards 33 are provided with vertical slots 38, and suitably mounted in such slots, so as to slide therein, are the bearings -12, which for convenience in assembling the parts are made in two sections and provided with flanges 43, which engage the sides of the standards 33 to prevent lateral displacement. Each of the bearings 42 is adjusted and held by a screwbolt 44, which passes through an internallythreaded aperture in a cross-piece -15 of the standard 33 and engages the under section 416 of the bearing -12, and a screw-rod 4-7, having a hand-wheel i8 and passing through a yoke or cross-piece 19 at the top of the standard and having a head at its lower end, swiveled in a socket 51 in the top of the bearingsections 52.
The die-roll 3% and bed 14C may be driven at the same surface'speed through the medium of any suitable means when the die employed is of such size as to complete a frame moving at the same speed as the die. l nasmuch, however, as picture-frames vary in the len th of the oval opening, to avoid a change of gears to vary the relative speed of the die-roll and reciprocating bed in order to draw out the design or the use of different dies with each \ariation in the size of the frames I provide in one machine means new to be described for varying the relative speeds of the die-roll and reciprocating bed as desired within certain limits, so that a die employed under normal conditions for a-certain size frame maybe used for a frame of the same width, but considerably longer.
Secured on the end of the shaft 17, opposite the gear 21, is a pinion 53, which meshes with and drives .an idle pinion 5a, which in turn imparts motion to a second idle pinion This latter pinion has fixed to it a larger gearpinion 56, which engages and drives a large gear-wheel 57, loosely journalcd on the extended end of the die-roll shaft 37, as shown in Figs. 1 and 7. The gear 57 is provided with a crank-pin 58, secured by a nut in an aperture 60, and pivoted at one end on such pin is a link 61, whose other end is pivoted on a stud 62, fixed on a slide 63. The slide 63 is designed to be adjusted on a block 6&, fixed on a stub-shaft or spindle 65, as shown in Figs. 9 and 10, and to this end may be provided with a dovetailed groove 66 to receive the block 6 1, which is shaped to lit into the groove. Set screws 67, passing through one side of the slide and engaging the block, are designed to set the parts and hold the slide in its ad usted position.
v and a cap or removable section 70, secured by bolts 71, as shown in Figs. 7 and 8. Fixed to the end of the spindle 65, opposite the block 64, is a gear 72, and to facilitate theremoval of this gear when necessary the end of r the spindle maybe tapered, as shown, to receive a sleeve 73, having a correspondinglytapered bore and which is held to the gear 72 by a key. The gear is clamped between a flange 74 on the sleeve and a collar 7 5 on the spindle by "means of a nut 7 6, screwing onto the threaded end of the spindle. Meshing with the gear 7 2 is an idle pinion 77, which in turn meshes with a stationary gear 78,
mounted on the shaft 37, which is free to turn therein. The gear 78 may be held against movement in any suitable manner, as by an arm 79, to the upper end, of which the gear 78 is fixed or cast and whose lower end engages a collar 80, loose on the extended end of the shaft 17. To permit of thevertical adjustment of the die-roll in the manner hereinbefore explained, the lower end of the arm 79 is provided with a vertical slot 81, and the collar 80, which is held against movement longitudinally of the shaft 17 by flanges 82, which embrace the opposite sides of the arm 79, is provided with flat sides fitting against the side walls of the slot. ,The collar is therefore held against rotation, but permits of the vertical movement of the arm as the die-roll 34 is raised or lowered.
Located on the reciprocating bed 14 is'a table 83, which is secured thereto in any suitable manner, as by bolts passing through flanges or clips 84} on the table. I The table 83 is designed to receive the pictureframe,
(shown in Figs. 1, 2, 4:, and 5and designated 85.) Which is positioned thereonand held against movement by any suitable means. Such means may consist of pins or studs 86,
projecting from the upper face of the table and adapted to engage suitable openings in the frame, as shown in Fig..2,.or, if desired, the table may 'be provided with properly spaced corner-blocks 87 to engage the pictureframe, as shown in Fig. 5.
Any suitable feeding means may be employed for delivering the putty to the frames. In Fig. 4: 1 have illustrated a device for the purpose and which, briefly described, consists of a tank or reservoir 88, supported above the bed and containing putty of the desired consistency, which is forced from the tank by mechanism which is not shownl The outlet I of the tank, located across the bottom of the same, is normally closed by a slide-valve 89, which is connected by a link 90 to one end of anarm 91, fixed on a rock-shaft 92. The slide-valve is designed to be controlled automatically, to accomplish which the shaft 92 is provided with an arm 93, which is engaged by a trip 94:, so positioned on the die-roll 34 as to open the valve just prior to the time when the forward end of the frame moves under the outlet-of the tank, and a second arm, 95, which projects in the path of a trip 96 on the reciprocating bed and acting after the frame has passed from under the delivery-outlet of the putty-feeding device. A second or regulating valve, 94, designed to follow the movement of the frame and effect delivery of the putty only onto the frame, is also provided, and consists of a suitable sliding plate located under the valve 89 and connected by a link 98 to one end of a bell-crank lever 99, pivoted on an arm 100, projecting from the tank. The other end of the lever 99 is pivoted to one end of a link 101, whose other end is pivoted on a crank-pin 102, adjustabl'y' mounted on a crank-arm 103, fixed on the shaft 37. As the shaft 37 turns the valve 89 is moved through the medium of the connections described and effects a deliveryof putty only onto the frame between the exterior edge and the opening. 7
The operation of the machine will be readily understood. A picture-frame having been placed on the table 83 and one of the belts 26 or 27, depending on the position of the ,bed, shifted onto the active pulley 25, motion is thereby communicated to the reciprocating bed and die, and as the frame is moved under the tank 88 the feeding mechanism-delivers putty to the frame, and such putty is pressed upon the frame. and embossed with the design of the roller as the frame passes under the latter. As soon as the frame has passed-the die the frame is removedand the driving-belt then shifted to its associated idle pulley and the other belt moved onto the active pulley, thereby returning the bed and die to their original position ready for a repetition of the puttying and embossing operation. When the stud 62 and spindle are on the same center and the gearing so related or proportioned as to move the reciprocating. bed and d1e-roll at the same surface speed,
the machine will then be operated with a die adapted to a particular size of frame-that is, one of such size as to properly putty and ornament a frame of the same area as the die. As thus operated, the motion communicated by the shaft 17 through the medium of pinion 53 and idle pinions 5A and 55 to th-egear '57 drives thearm 68 by means of the link 61, and although the gear 72 and idle pinion 77 are moved around the stationary gear 78 they exert no influence over the movement of the roll, which is then synchronous with the reciprocating bed. When, however, it is desired to "employ the same die with a frame; longer than the die, the slide-plate 63'is moved a distance on the block 6 1, depending on the diflerence in the length of the.die and frame and which may be readily. determined by ex;
periment. This sets the stud 62 eccentrically with reference to the spindle and results in a crank action between end of the link 61 about the spindle, due to the turning of the gear 72 about the stationary gear 78, and is productive of a dragging or lagging of the arm 68, and consequently of the die-roll 34, to which the arm is keyed at certain periods in its movement. Assuming that the die used has a surface length of two feet and the frame to be p uttied is two feet two inches, the slide 63 is adjusted sufficientl y to effect a retardation of the movement of the roll to compensate for this difference. Starting with one end of the frame at the advanced edge of the die, the surface speed of the bed and die are at the beginning of their movement synchronous; but owing to the eccentric disposition of the stud 62 and spindle 65 the stud is turned around the spindle as a center by the pinions 72 and 77 and stationary gear 78, exerting a gradually-increasing lagging effect on the die-roll until the center of the frame is reached, when the movement of the drum is gradually accelerated to the opposite end of the frame, where it attains the surface speed of the reciprocating bed again, or the position of the parts may be so adjusted that the die-roll moves slowly at the beginning of its movement, then increases in speed to the center of the frame, and then decreases in speed from the center to the other end of the same. The die-roll never makes more than one rotation and usually less than a complete rotation, so that it will be seen that the movement of the arm is, in effect, oscillatory. The machine is started by means of the beltshifters 30 and 31, heretofore referred to, and each of which iscarried by a sliding rod 104 and 105, supported at one end by an extension of the support 32, as shown in Fig. 7, and at the other end by brackets 106, fixed to the frame, as seen in Fig. 4:. Each rod has a collar, to Which is pivoted one end of a link 107, whose other end is pivoted to a handlever 108. The inner end of the lever 108 is fixed to a vertical spindle 109, turning in a sleeve 110, secured by bolts 111 to the side rails 10 of the frame. By moving either lever 108 the belt controlled thereby may be moved onto or off the active pulley 25 at will to start or stop the machine. Preferably, however, means are provided for stopping the machine automatically. For this purpose the spindles 109, to which the levers 108 are fixed, are located at opposite sides of the die-roll, as shown in Fig. 4:, and each spindle is provided with a finger 112, which when the belt controlled by the shifter associated with such spindle is on the active pulley 25 projects in the path of one of the trips 96, adjustably mounted in guide-slots in one of the side rails and secured in position by bolts 114. In the operation of the machine when one of the lingers 112 is engaged by its associated trip 96 the spindle 109 of such finger is turned, thereby sliding its belt-shifting rod and moving the active belt onto its idle pulley. By adjusting the trips 96 the movement of the bed may be varied, as necessary.
The gearing of the machine is preferably so mounted and arranged as to be capable of removal or adjustment in order to eil'ect any desired variation in the speed, and it will be obvious that the relative speed of the die-roll and reciprocating bed may be readily changed by substituting other gears for those communicating motion from the shaft to the die-roll. The idle pinion 77 is preferably journaled on a stud 115, secured to a plate 116, pivoted at 117 to the arm 68, so as to be capable of adjustment in case other gears are substituted for the gears 72 and 78. To secure the plate 116 against movement, the arm 68 may be provided with a slot 118, in which moves a belt 119, passing through the plate, and by means of which the latter may be clamped to the arm. The idle pinions 54: and 50 are mounted in such manner upon a movable member as to permit of the adjustment thereof when the die-roll is raised or lowered. To this end the pinion 54. is journaled on a sleeve 120, which is carried by a stud 121, suitably mounted in a slot 122, formed in a bracket 123, pivoted on the shaft 17, and the pinions and 56 are pinned together and similarly mounted, as shown in Fig. 3, on a sleeve 124 on a stud 12:), movable in a slot 126 in the said bracket. Both studs 121 and 125 are secured by nuts 127, and the pinions are retained on the sleeves associated therewith by collars 128 and 129. The pinions are capable of independent adjustment, and the bracket 123 may be moved as necessary to adjust the pinions carried thereby. The bracket is held against movement by a bolt 130, which passes through a. slot 131 in the bracket and serves to clamp the same to the adjacent rail of the frame. By moving the bracket 123 and adjusting the pinions journaled thereon the drivingconnection may be readily established irrespective of the adjustment of the die-roll.
