MACHINE FOR MAKING FRAME-BODIES.
Specification of Letters Patent.
Patented Jan. 10, 1911.
Application filed November 1, 1909. Serial No. 525,627.
To all whom it may concern:
Be it known that I, JACOB MUELLER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Machines for Making Frameldodies, of which the following is a specificatlon.
This invention relates to machines for making frame bodies and designs to provide an improved machine of this type.
The frame bodies which this machine is designed to manufacture, consist of layers of thin sheets or strips of veneer, paper, pasteboard or the like, which are glued together,
and said frame bodies are generally of oval, elliptlcal or round form, and used for fram pictures, photographs, mirrors and the i re.
This machine has been designed to build up stock from which the individual frame bodies are cut and afterward treated to make the finished frame.
The invention consists in the several novel features of construction, arrangement and combination of parts described in this specification and particularly pointed out in the claims.
The invention is clearly illustrated in the drawings furnished herewith, in which Figure 1 is a view of the machine partly in side elevation and partly in vertical longitudinal section, the line of sect-ion being taken at 11 in Fig. 3, Fig. 2 is a fragmen'tal side view of a bracket, and a certain swinging frame and parts carried thereby,
Fig. 3 is a front view of the machine looking in the direction of the arrow 3, Fig 1, but omitting the wrapping belt and the parts that are located in the rear of the machine, Fig. 4 is a detail horizontal section taken on the line 4-4: of Fig. 1, Fig. 5 is a detail rear View of one member of the swinging frame seen in Fig. 2, Fig. 6 is a similar View of the other member of said frame, Fig. 7 is a detail vertical section taken on the line 77 of Fig. 1, Fig. 8 is a view partly in front elevation and partly in vertical cross section, the line of section being taken at 8-8 in Fig. 1, Fig. 9 is a detail cross section taken on the line 99 of Fig. 1, Fig. 10 is a view of a certain bracket for supporting the spindle of the mandrel, the view being partly in side elevation and partly in section, the line of section being indicated at 1010 in Fig. 3, Fig. 11 is a side View of one of the strlps or sheets of material from which the frame bodies are built up and Fig. 12 is a perspective view of one complete frame body before it is cut up into individual frames.
In the drawings A, represents a supporting frame, which-is arranged to carry the operative parts of the machine. This frame may be of any substantial construction, and as shown, comprises longitudinal base members 10, transverse base members 11, upright members 12, which extend up from the base members, inclined members 13, that connect the upper ends of the upright members 12,
with the base members, intermediate horizontal members 14;, that connect the upright with the inclined member and cross members 15, that connect the two sides formed by the uprights, inclined members and intermediate horizontal members. This arrangement forms a very substantial frame work capable of sustaining the operating parts of the machine.
To one side of one of the upright members 12, is a post 16, whichis connected to said upright member by horizontal struts 17, and secured, upon said upright member 12, and post 16, are brackets 18, that support bearings 19, which carry the spindle 20, of the mandrel or winding head 21. The bearings 19, are longitudinally.adjustable upon said brackets 18, and as shown one means for accomplishing this result is to form the horizontal arms 22, of the brackets with longitudinal grooves having overhanging edges against the under .side of which may be placed the heads of bolts 23, that bolt the bearings 19, to the brackets. It is evident that by loosening the nuts upon the threaded ends of the bolts, the bearings 19, can be thereon by any suitablemeans', as for in-- stance by a collar 24,.wh-ich is secured to the spindle and a nut 25, that is threaded upon the end of the spindle. The mandrel or winding head 21, may be loosely journaled upon the spindle or rigidly secured thereto and the spindle rotatively mounted in the bearings 19. Washers 26, are secured upon the spindle to prevent endwise movement thereof. The curved face of the mandrel may have any desired contour upon 1,10
partially surrounds said mandrel.
which the frame body is built up and said frame body naturally takes the shape given it by'the mandrel.
Means are provided for wrapping the sheets of material tightly around the mandrel and snugly against each' other and one arrangement for accomplishing this result consists in a flexible element here shown in the form of an endless band or belt 27, that The belt fpasses about a pair of rollers 28, 29, which the axis of rotation of the mandrel. important, however, to hold said rollers and loop tlghtly upon the mandrel and the frame are-spaced apart sufliciently to. permit the operator to insert the material between them, and said rollers are mounted so as to be capable of movement toward or away from It is body that is being built up thereon, otherfwise only poor results can be had in making up the frame body. The lower roller 29, is carried by a swinging support or.
' frame'B, which is shown as fulcrumed upon the frame of the machine at 30. The frame may be built up of long upright members 31,
between which are journaled rollers 32, 33.
:The roller 29, is shown as journaled in bearings on the ends of two arms 34, that are spaced away from the long arms'31, by struts 35. The shaft 30, is journaled in I boxes-36, secured to the long arms 31, and
be had in pressing said roller against the 'mandrel.
in boxes 37, here shown as secured upon horizontal members 38, which extend out 'fromthe upper ends of the upright meml bers 12, of the frame, and are braced thereon as for instance by arms 39, to make a rigid support. It is quite important that the upright arms 31, of the swinging frame B, be
pivoted at quite a distance above the roller 29, in order that considerable leverage may The upper roller 28, is carried by a swinging support or frame C, which is journaled at 40, to brackets 41. Said swinging frame [(3, comprises two members 42, 43, one of V [which is longitudinally movable with respect 5 48, that are guided between the bars 44, and
to the other, whereby the roller 28, which is carried by the slidable member, may be 'moved away from the roller 29, in loosening the wrapping means'from the mandrel whenever the frame which has been built up on said mandrel is to be removed. The mem- 'ber 42,- of the swinging frame C, comprises v, a frame like structure, preferably made u of side members comprising bars 44, which have strips4'5, secured thereto that overhang the inner or adjacent edges of the bars 44, to
provide guides for the movable member 43. The upper ends of the side members are conslide up and down in the guides thereon. The side bars 48, are connected by struts 49, and have bearings '50, upon their lower ends in which is journaled the upper loop forming roller 28. A shaft 51, isjournaled in bearing blocks 52, secured to the member 42, and bears pinions 53, that mesh with rack bars 54, that are secured to the side bars 48,
of the sliding member 43. One end of the shaft 51, bears a gear wheel 55, that meshes with a gear wheel 56, upon a shaft 57, journaled in the bearing blocks 52, and said shaft 57, bears a crank wheel 58, upon one end by means of which it may be rotated. A ratchet wheel 59, is secured upon the other end of the shaft 57, and cooperates with a pawl 60, to prevent retrograde motion of the shaft 57. It is obvious that by turning the crank wheel 58, in the proper direction, the sliding member 43, can be raised to separate the rollers 28, 29, and that the pawl and ratchet mechanism will hold the same in such raised position.
Mechanism is provided for rotating the roller 28, and thereby moving the belt 27, around the mandrel and as shown comprises a sprocket wheel 61, secured on one end of the shaft of the roller 28, which sprocket wheel is connected to a sprocket wheel 62, on the shaft 40, by a sprocket chain 63. The shaft 40, is driven from a counter shaft 64, by a sprocket chain 65, that passes over sprocket wheels 66, 67, on the shafts 64, and 40, respectively. The shaft 64, bears a sprocket wheel 68, which is connected to a sprocket wheel 69, on a counter shaft 70, by a sprocket chain 71, and said counter shaft 70, bears a gear wheel 72, which meshes with a pinion 73, fast upon the main drive shaft 74, which bears a loose pulley 75, that may be clutched thereto by a clutch mechanism 76. An idler 77, operates to take up the slack in the sprocket chain 71. I have provided sprocket wheels 78, 79, 79*, upon the shafts 64, 70, which sprocket wheels are of different sizes and adapted to provide means for varying the speed at which the roller 28, is driven. By simply shifting the chain 71, from one set of sprockets to another, the belt I can be given more or less speed, as the case may be.
Means are provided for putting tension upon the endless belt 27, and as shown a simple form of tension device comprises a movable weight carrying frame 80, which travels upon tracks 81, secured to the inclined members 13, and weights 82, that are supported by said frame. The belt 27 runs around a pulley 83, which is mounted on a shaft 84, journaled in'bearings upon said frame. Idle rollers 85, 86, are provided near the upper end of the frame to form the loop in the belt which extends around the pulley 83, and a pulley 87, is journaled near the lower end of the frame around whiclr go the belt passes after leaving the swinging frame B. A stop 88, is provided near the lower end of the inclined members to receive the weight carrying frame 80, whenever the loop in the belt is released from the mandrel. I have found that in making elliptical or oval frames whose major axis is much greater than the minor axis, considerable pressure of the roller 29, required and for this reason the belt is threaded around the roller 33. More leverage is thus obtained and the roller 29, pressed more firmly against the mandrel.
It is to be observed that the roller carrying frames B, C, are so pivoted with relation to the mandrel, that the movements of the rollers 28, 29, toward and from the axis of rotation of the mandrel, are in approximately parallel lines, whereby the space between rollers may remain substantially constant, thereby causing the loop in the belt to practically surround the mandrel during operation of wrapping the sheets to form the frame. Furthermore the pull of the tension device upon the belt operates to draw the rollers 28, 29, and the loop upon the mandrel.
D, represents one of the sheets of veneer, cardboard, or the like, from which the frame bodies are made, and E, represents a complete frame body built upon this machine.
In operation the drivingv mechanism is started; the first sheet D, is fed in between the rollers 28, 29, and wrapped around the mandrel. or winding head by the wrapping belt which is driven in the direction of the arrow by the driving mechanism. A. second sheet is then coated on one side with glue and fed in between the rollers with the glued side next tothe first sheet and said second sheet wrapped around the first by the wrapping belt. This operation is continued until a frame body is built up having the required thickness. In place of sheets, one long continuous strip may be used. The machine is then stopped, the sliding member of the swinging frame C, raised to separate the rollers 28, 29, and thereby release the loop from the mandrel and the built up frame body taken off the mandrel. It is understood that the tension device falls to the stop 88, as soon as the sliding member of the swinging member C, is raised somewhat, whereby the belt slacks up around the mandrel as the sliding member is further raised. If desired, the mandrel may be slightly tapered as seen in Fig. 7, to permit the frame body to be removed more readily or the mandrel may be of any well known collapsible form to facilitate the removal of the frame body. After the frame body is removed, it is placed in a holding device of some sort until the glue sets, and then is sawed up into a large number of independent frames which may be "Letters Patent 1.
