To all whom it may c0nccm.'

Be it known that I, FREDERICK M. BALD- WIN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Oil-Cloth-Cutting Machine, of which the following is a specification.

My invention relates to oil cloth cutting machines, being more particularly a table upon which oil cloth and articles of similar characteristics, such as paper,cloth and the like, may be cut into desired lengths, and one of the principal objects of my invention is to produce a machine of the character described, of simple form and construction in which the oil cloth may be placed upon a table in a roll and pulled out on the table to the required length, such length being indicated by an indicator for that purpose, and the oil cloth cut as desired. h

Other objects and advantages will appear hereinafter from the following specification.

Referring to the drawings, which are for illustrative purposes only, I

The roll 25 being placed upon the table,

theend of the roll is pulled forwardly'over the table, one edge being engaged by the measuring device and the free end of the roll being engaged by a clamping device on the winding mechanism.

supported on' suitable legs 21, such legs hav- The measuring device comprises a box 26 which forms a housing for any well known form'ofcounting mechanism, such box having a dial 27 on its upper face marked in feet or yards as desired, an indicating arrow 28' being operated by the counting mechanism as the oil cloth is moved under the measuring device. One edge of the oil cloth inclicated at 30 passes under a roller '31 mounted in the box 26 and connected to the counting mechanism, being engaged between such roller and smaller rolle'rs32 mounted in the table top. The oil cloth passing between such rollers rotates the-roller 31 which imparts movement to the arrow 28 through the counting mechanism therebydndicating the amount of oil cloth pulled under the roller 31. g

The boXJ26 hinged as indicated at 33 to any suitable support or to the table andis provided with a stud 34 on one side thereof which is engaged by a loop 35 formed in one end ola rod 36,-.such' rod being con nected to the short end 37 of a stop 88 pivsteam 39. to the table top, such stop 38 having a toe 40 formed upon the outer end The oil cloth to be measured box 26 having been moved into the dotted line position'show n F 6, which move ment oi the box swings the stop 38 into the dotted line position shown in Fig. 5, the toe 40 of the stop extending forwardly on the table to approximately the line upon which the oil cloth is finally cut, or in other words, into the path of the cutters hereinafter cescribed; The free end of the oil cloth is pulled forwardly over the rollers 32 until it strikes the toe 40 of the stop 38 when in the dotted line position shown in Fig.

5, whereupon the box 26 is moved down to full line position with the roller 31 in en'- tends into the open ends of the end pieces and 44, the end piece 43 being slotted as indicated at 46 and the roller havinga pin 47 thereon which extends into the slot 46. Behind the end of the roller in the end piece 43 is a coiled spring 48 which elastically holds the roller 45 in the end piece 44, but allowing for the length of the roller 42 to be varied. The

end pieces

43 and 44 are each provided with a spur 50 received in sockets 51 on the ends of shafts 52 and 53. The shaft 53 is mounted in a housing 54, this shaft being provided with a gear 55 which meshes with a gear on a shaft 57, the housing 54 being secured to the table in any suitable manner. The shaft 52 is mounted in a housing 58 and is also pro vided' with a gear '59 which meshes with a gear 60 on the shaft 57, such shaft 57 being square in cross-sectionfor the purposes here- 'inafter described and the gear 60 being slidably mounted upon the square portion of the shaft 57 with an extension 61 having a recess 62 out therein to receive the lower portion of the front angle iron 20 of the table, being arrangedso that the housing will slide thereon and prevent the housing from tilting out 7 of position on the hub 63 of the gear 60 which forms a support for the housing One end 64 of the shaft 57 is rounded and 1S mounted 1n a bracket 65 secured to the table in any suitable manner On the inner Side of the gear 55 and the gear 59is mounted a circular plate '67, such circular mounted on a pin 71 to the gears and 59,

such arms being elastically held apart by means of a coiled spring 72 placed between the upper ends of the same. The arms are provided with half round lugs 73 which extend forwardly to receive the end of the oil cloth thereon, the end of the oil cloth being passed between the lugs'73 and the extension 69 when the arms 70 are in collapsed position due to pressure exerted on the arms by the fingers of the operator. When such pressure is removed the arms operation of the handle 75 is disconti The housing 58 is provided the plates 8.; and

assume the position shown in Fig. 10 in which position the lug 73 on one arm engages the end of the oil cloth between such lug 73 and the fixed extension or clamping .member 69, lifter the oil cloth is so attached the oil cloth is drawn forward by the operation of a handle 75 mounted on the I end of the shaft 57. The shaft'57 has a hollow housing 7 6 formed thereon, one end 77 of which abuts against the end of a hub 78 formed on thevgear 69. The housing 76 has a coiled spring 79 therein, one end of which abuts against the end of the housing 7 I and the other end against a flange 80 formed on the shaft 57, such spring tending to hols wardly and the narrow width of oil ClOill attached to the clamping device that such clamping device holds the housing 58 in the inward position until the cutting operation is accomplished. The operator winds the Oll cloth upon the roller 42 until the arrow 28 indicates upon the dial 27 the amount of oil clot-h desired to be cut, whereupon the nued and the cutting operation accomplished.

This cutting operation is performed by a cutter generally indicated at 1.7, which travels across the front portion of the table between the angle iron 20 and a larger angle iron 82 which together form the knife carriage or cutter guide, such angle iron 82 also supporting the-forward portion of the table indicated at 83. The knife carrn comprises a rear plate 84, a front plate secured to the rear plate in any suitable manner, the rear plate having a rearwardly extending flange 86 upon which is mounted a roller 87, a shaft 88 being provided for this purpose, which extends through a bottom plate 89. A similar roller 90 is provided to engage the side of the guide 82, such roller 90 being mounted on a shaft 91 on the plate 89- as clearly shown in Fig. 7. Mounted in are shafts 92 and 93, the shaft 92 being above the face of the table and the shaft 93 being below the face of the same, such shafts having; shoulders formed thereon and being riveted overthe housing ting disk 100 having a fiat face which is overlapped by the flat face of a cutting disk 101 mounted on the gear 95, the disk 101 being elastically held against the face of the disk 100 by a disk spring 102 clearly shown in Fig. 7. It will be noticed that the cutting disks move in the direction of the rows indicated at 103 in 8 and that the meeting point indicated at 1042 or" the cutter is slightly above the face of the table so that the oil cloth will be cut as the knife carriage is moved across the face of the table by the I mechanism hereinafter described.

The mechanism for operating the knife carriage consists of a series of links, arms and levers so arranged that a great length of travel of the cutter is accomplished with the operating mechanism confined within a very compact area. lPivotally connected to the under side of the knife carriage by means of a bolt 105 is an outer telescoping member 106 arranged to receive an inner telescoping member 107 consisting of red, one end of which is freely slidable in the member 106 and the other end of which is pivotally mounted at 108 to the rear portion of the f 'ame of the table. 109, 110 and 111 indicate brackets secured to the frame of the table, the bracket 110 having pivotally mounted thereon a primary or central arm 112. The brackets 109 and 111 have pivotally mounted thereon respectively, ondary or side arms 113 and 11 1. The outer end of the secondary arm 113 is pivotally connected through the medium of a link 115 to the telescoping member 106 and. the outer end 01 the arm 11 1- is pivotally con nected to the telescoping member 106 by a link 116, the

links

115 and 116 being both pivotally mounted upon a pin 11? mounted on the member 106. The outer end of the central or primary arm 112 is provided with a stud or belt 118, which bolt pas. as through a slot 119 in a link 120, the other end oi which is pivotally mounted 121 on the side arm 113. The stud 118 also extend. through a slot 122' formed in one end of a link 1233, the other end of such link being pivotally connected at 12 1 to the arm 11%.

125 designates an operation lever which is operated at the side of the table, being pivotally mounted to the table by means of pin or stud 126. The operating lever 125 is connected by means of a connecting rod 12"? with the central arm 112, such connection being made by means of a pin 128 mounted upon the arm 112 approximately centrally of its length. The operating lever 125 is provided with a handle 130 which is formed by bending one end of the operating lever outwardly as shown in 2. A. support is provided for the'connecting rod 127 which consists of a h 131 which is W a F 1 W mounted u on -e lfii. e oi we ti-ple by means of a clip 132.

table.

The above operating mechanism operates as follows:

By swinging the operating lever 125 from the full line position shown in Fig. 2 to the dotted line position the connecting rod 127 swings the primary arm 112 from the full to the dotted line position. Such movement of the primary arm pulls the link 120, and through the medium of such link operates the side arm 113 which in turn, through link 115, operates the member 106. The member 106 telescopes with the member 107 and moves into the dotted line position shown, thereby drawing the knife carriage across the table and cutting the oil cloth. 7

The knife carriage .is returi'ied by moving the operating lever back into the full line position shown, in which case the primary arm 112 operates link 1.23 which in turn operates the side arm 11 1, and through link 116 pushes member 106 back into the full line position ready for another cutting operation.

Means are provided also for holding down the oil cloth adjacent to the line of cutting, such means comprising a holding finger 13st at one end of the table and holding

fingers

135 and 136 at the opposite end of the table. The finger 134 is mounted upon a shaft 137, the shaft 137 being supported. in a bracket 138 on one side of the table. Mounted upon the bracket 138 by means of a stud or pin 139 is a locking arm 140, one end of which is curved outwardly and upwardly to the outside of the handle 130 of the operating lever, as shown in Fig. 3, such end being provided with a knob 141. The other end of the locking arm M0 is pivotally connected by means 01 a stud or pin 142 with one end of a red 1413 which rod 141-3 operates the

fingers

135 and 136 through the mechanism hereinafter described. V

The locking arm 1 10 operates the shaft 137 through the medium of link 14h one end of which is secured to the shaft 137 and the other end of which is secured to the stud or pin 1412. The rod 143 at its other end is connected to one end oi": a rocker arm 1415, such rocker arm being pivotally mounted on'a bracket 146 to oneside of the The other end of the rocker arm 1 15 is connected by means of a link 14.7 with an shaft being journaled upon the .frzirneo'f the machine and having mounted on one end thereof

135 and 136, the shaft between such fingers being l in t shape as indicated at 150 in p to allow for passage of the knife ca between such fingers, it being and the

fingers

135 and 136 press upon theoil cloth on each side of the cutting line. The lock ing arm 14-0 is arr; d so t the ing lever 125 cannot be operated 1 holding

fingers

134i, 135 and 136 are moved arm 1.4-8 mounted upon a shart 1 19, such v release the oil'cloth such springs acting re-.

into engagement with the oil cloth, the looking' arm,when bringing the fingers to such engaging position, moving into the dotted line position shown in Fig. 3 thereby clearing the path of the handle of'the operating lever 125. Elastic means are provided for holding the locking arm .in the path of the handle of the operating lever, which consist of a spring 151 which operates upon the rocker arm 1 15 to place an elastic tension upon the same and transmit such elastic tension through the rod 143 to the locking arm.

The box 26 is preferably elastically held in lower position so that the roller frictionally engages the oil-cloth. This is accomplished by mounting a leaf spring 155 on the end of the box 26 arranged to engage a rod 156 mounted on the table of the machine, such spring 155 swinging under the rod when the box is moved to upright position.

In the form of cutters shown in Fig. 12, two sets of

cutters

158 and 159 are driven through the medium of gears 160, such gears being driven by the rack 99. lVith this form of cutting device the material may be cut by drawing the cutters in one direction in which one set of cutters perform the cutting operation after which the material may be drawn out and another length cut by moving the cutters in the opposite direction, cutting the material by the other cutters.

By using my machine in the manner above described it will be readily understood that oil cloth, paper or similar articles commonly handled in rolls may be readily cut and dis pensed with accuracy and despatch. it is understood that the oil cloth after being wound upon the roller 12 may be easily removed therefrom by removing the roll from its supporting mechanism and the roil slipped out of the cloth wound thereon, it being understood that a wooden roller may be used in place of the collapsible roller shown and described, such wooden roller being of the type commonlyused for'shipping small quantities of oil cloth rolled thereon, in which case the roller would re main in the oil cloth.

The springs A8 and 79 have an additional function to that heretofore described, namely, when the fingers are pressed together to spectively against the shaft 52 and housing 76 return the housing 58 to its original position.

While I have shown and described my invention as applicable to cutting oil cloth it is to be understood that I do not limit my invention to such use but it can be used for handling all flexible material whether cloth. paper or similar articles.
