' (c1. s1 z72) 2 Claims. 1
This invention relates to a quick set wheel guard.
An object of this invention is the provision of. an efiicient safety guard for protecting an operator or bystanders against flying particles cast from an emery wheel, or any other type of machinery, tools or fixtures, which the safety guard may be adapted to.
Another object is the provision of a safety guard which is easy to adjust for placing the safety glass in the proper location for different types of work without the means of additional tools, equipment, or the lost time usually taken to adjust said equipment.
A still further object is the production of a device that is simple in construction, low in cost, and very efllcient in operation.
With the foregoing and other objects in view, this invention comprises certain novel constructions, combinations, and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.
In the drawings:
Figure 1 is a top plan view of a device constructed in accordance with this invention.
Figure 2 is a view in side elevation.
Figure 3 is a sectional view, taken on line 33, Fig. 2, and looking in the direction of the arrows.
Figure 4 is a view in elevation of the outer end of the device shown in Fig. 2.
Figure 5 is a view in elevation of the rear end of Fig. 1.
Figure 6 is a front view in elevation of a machine to which the device is applied, while Figure '7 is a top plan view.
Figure 8 is a view in side elevation, showing the device applied to the machine.
Referring to the drawings, in which the preferred embodiment of this invention is illustrated, l designates the primary bracket which comprises a flat base 2 and flanged edges 3, 3. Projecting outwardly from said flat base 2 are a series of cups 4; these cups are arranged in a semicircle for the efficient operation of the device.
A swinging arm 5 is mounted on the base 2, and is secured by means of a bolt 6. The flanged edge 3 of the primary bracket is provided with an aperture 7, which is adapted to receive a bolt 8 when it is desired to attach the device to the guard 9 of the machine Ill.
The swinging arm 5 is provided with parallel flanges II, which strengthen the arm. A spring holding casing i2, Fig. 3, is secured to the arm 5 between flanges II, and a coil spring I3 is positioned in said casing l2. A ball I4 is under spring IS. The ball I4 is adapted to rest in any one of the cups 4 for securing the arm 5 in an adjusted position.
On the outer end of arm 5 is secured a shield bracket l5; this bracket I5 is held securely in place by means of a bolt IS. The shield bracket l5 comprises an angle body [1, which is fastened by bolts l8 to the top of frame l9. Within frame [9 is mounted a pane of glass 20. This glass 201s strong and durable, and cannot be broken by particles hitting against same.
In operation, the operator can swing arm 5 to any desired position, so as to place the shield bracket i5 and its glass guard in the best position for protection against flying particles from the emery wheel 2|. The device will frictionally be held in the desired position by the action of the ball I 4' seating in a cup. In other words, the locking of the arm 5 in any adjusted position is automatic, with no tool or other equipment required for the adjustment and the positive securing of the device in its adjusted position.
The angle bracket l5 has the outwardly extending portion [5a for for the bolt Hi to extend through, while the inwardly extending portion i512 may be used by the operator as a grip, during the adjustment of the device.
While I have described the preferred embodiment of the invention and illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same, and I, therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claims.
What I claim is:
1. In a device of the class described, the connbination of a primary bracket, said bracket including a base provided with a plurality of outwardly extending cups, a swinging arm attached to said bracket, said arm provided with a springholding casing, a coil spring in said casing, a ball under said spring and being adapted to seat in any one of said cups, and said arm provided with shield-carrying means.
2. In a device of the class described, the combination of a primary bracket provided with a flange, said flange provided with an aperture, said primary bracket provided with a semicircular row of outwardly extending cups, an arm pivotally mounted on said bracket to one side of said cups, a spring holding casing on said arm and registering with said cups, a coil spring in said spring holding casing, 21. ball under said spring and being adapted to seat in any one of said cups, and a shield bracket provided with a glass fixedly secured to the outer end of said arm, substantially as shown and described.
