3 Claims. 35-32) This invention relates to a glass cutting device, and an object of the invention is to provide a device of this character especially designed for cutting window glass.

Among the objects of the invention is to provide a cutting device of this character characterized by simplicity of construction and operation.

A still further object of the invention is to provide a device of this character whereby the sheet of glass may be cut into any desired number of sections, and also into sections of varying width in a single operation.

The invention together with its objects and advantages willbe best understood from a study 7 of the following description taken in connection with the accompanying drawings wherein:

Figure 1 is a top plan view of the device.

Figure 2 is a side elevational view thereof.

Figure 3 is a transverse sectional view.

Figure 4 is an enlarged fragmentary plan view of a portion of the table.

Figure 5 is a fragmentary longitudinal sectional view through the table, and

Figure 6 is an enlarged detail view showing the mounting for the cutter arms.

Referring to the drawings by reference numerals it will be seen that the improved cutter includes a table indicated generally by the reference numeral 5, a plurality of cutter arms 6. pivoted above the table and remote control means for raising or lowering the arms relative to the table whereby a selected number of certain arms may be employed for cutting the sheet of glass 1 into the desired number of sections, and also into sections of desired widths.

The table 5 comprises a top 8 supported by legs 9 and attached to the legs 9 through the medium of brackets Ill.

Movable relative to the top 8 is an endless apron or conveyor which comprises a pair of endless side chains trained over sprockets l2, l3, and M respectively. Sprockets 2 and M are provided on the ends of shaft journalled in suitable brackets l6 provided at respective opposite ends of the table top 8. The sprockets |3 are provided on suitable shafts suitably mounted intermediate the end of the table top.

The chains l are connected together through the medium of strips ll of wood or other suitable material which at their under sides are hingedly connected together as at I9. The top of each strip I1 is covered with a strip of felt or other suitable material 20.

Suitable means indicated generally by the reference-numeral 2| is provided for connecting the endless apron or conveyor with a source of power for driving the conveyor. r

Arranged adjacent one end of the table is a supporting frame for the cutting arms 6. The frame comprises a pair of opposed standards :22 disposed at opposite sides of the table and having suitable base ends 23 resting on the floor or other suitable supporting surface. At, their upper'ends the standards 22 are connected by a 10 cross bar 24.

Slightly above. the table 5 the standardsZZ are connected by a fixed pivot rod 25 and the arms 6 at one end are provided with split sleeves 6a through the medium of which the arms area connected to'the rod 25 to swing relative to the rod 25 as the pivot.

Projecting laterally from the standards 22 are substantially triangular brackets 21 which supporttherebetween a stop rod 28 for the arms {6 as best shown in Figure 6. As is obvious the rod 28 limits the downward swinging movement of the arms 6.

At the free ends the arms 6 have downwardly angularly directed end portions equipped with suitable cutting elements or points 29 which latter may be made of precious stone such as diamond or the like.

Adjacent said free end the arms 6 are provided with eyes or the like 30 through the medium of which one end of flexible cords or cables 3| ar connected to the arms 6.

The cables 3| are trained over pulleys 32 suspended from the bar 24 as at 33.

The cables 3| are divided into two series one series of which are directed in one direction and the other series of which are directed in an opposite direction to terminate laterally of the table 5.

Suitably mounted at opposite sides of the table and remote therefrom are control boards 34 equipped with brackets 35 on which are pivotally mounted control handles 36 to one end of which the cables 3| are connected as clearly suggested in Figures 1 and 2. Thus by proper manipulation of a lever 36 a selected arm 6 may be raised out of contact with the glass 1 to the end that a selected number of such arms 6 may be used dependent upon the widths or variations in width of the sections into which the sheet 1 is to be cut. The operation and utility of the device is thought to be apparent from the foregoing, and will be better appreciated, from a study of the following brief description of operation.

In operation the window sheet of glass indi- 55 cated by the numeral 1 as suggested by broken lines in Figure 2 is placed on the endless conveyor of the table at the left hand end of the latter. In this manner the plate glass 1' is carried by the conveyor under the arms 6 to be drawn by contact thereof with the scoring points 29 with which the arms are equipped. Obviously by bringing selective arms 6 into use the window glass may be cut into strips or sections varying in number and width.

To maintain the arms 6 in properly spaced relation there are provided on the stop bar any required number of pairs of upstanding pins 31 between each pair of which an arm 6 operates as clearly suggested in Figures 3 and 6.

Referring again to the arms 6 it will be noted that each of these arms include a pair of telescoping members Bb, 60, which are secured together at the desired relative adjustment through the medium of a set screw 38.

As clearly shown in Figure 6 the section 6b of each arm is provided with the clamp Ba that loosely embraces the pivot rod 25 while hinged to the free end of the arm member 60 as at 39 is a head 40 provided with a laterally extending arcuate arm 4| formed with an arcuate slot extending substantially from one end to the other thereof and through the head 40 to accommodate bolt and nut means 42, the bolt of which extends through a suitable opening in the upper portion of the shank of the cutting point 29.

With this structure it willbe apparent that the arms 6 may be lengthened or shortened as found desirable; that the head 40 and associated parts may be swung upwardly in a vertical plane relative to the arm member 60 when desired for any purpose; and that the points 29 may be adjusted laterally relative to the head 40 as also may be found desirable, thus providing for the cutting arm and associated parts a structure permitting of a wide range of adjustments.

Having thus described my invention, what I claim as new is:

1. In a sheet glass cutting device, the combination of an endless carrier upon which the glass travels, standards disposed at opposite sides of the carrier, a cross bar connecting the upper ends of the standards, a rod connecting the intermediate portions of the standards slightly above the carrier, a plurality of cutter arms independently connected with said rod for vertical swinging movement about the rod as a pivot, pulleys suspended from said cross bar, and operating cables for said arms trained over said pulleys and connected at one end with said arm.

2. In a sheet glass cutting device, the combination of an endless carrier upon which the glass travels, standards disposed at opposite sides of the carrier, a cross bar connecting the upper ends of the standards, a rod connecting the intermediate portions of the standards slightly above the carrier, a plurality of cutting arms independently connected with said rod for vertical swinging movement about the rod as a pivot, each of said cutter arms including a pair of telescoping sections, means for securing said sections at the desired adjustment relative to one another, a head hingedly mounted on the free end of each cutter arm, and a cutting point carried by said head; and means connected with said arm for swinging the latter about said rod as a pivot.

3. In a sheet glass cutting device, the combination with an endless carrier upon which the glass travels, standards disposed at opposite sides of. the carrier, a rod supported between said standards slightly above the carrier, and a plurality of cutter arms independently connected with said rod for vertical swinging movement about the rod as a pivot, each of said cutter arms including a pair of telescopic arm sections having means securing said sections at the desired adjustment, a head hingedly mounted on the free end of one of said sections and provided with a lateral arcuate extension having a slot extending from one end to the other thereof, and a cutting point having a shank provided with bolt and nut means operating in said slot.
