To allwhcmtmet/ coef/rec.' Y
Be it known that I, CARL F. Gaswnnr., a citizen of the United States, residing at Goon- Rapids, inthe county of Carroll and State of Iowa, have invented a new and useful Glass Tongs, of which the following is a specification.
My invention relates to improvements in glass tongs.
Numerous devices have been employed for handling plates ofy glass. The common rubber hand pads and slings usually employed meet with'` more 'or' less success in the hands of experienced membut theyhave failed inthe hands of inexperienced users, who are timid in undertaking the risks involved in* handling large and' expensive glass plates.
It is the purpose of my present invention to provide a simple, durable andinexpen- K f Eachblock 22 is formed with a central apersive device'adapted to securely grip plates of glass' or like objects and furnish means for 'conveniently carrying the same.
A further object isv to providea gripping device of this kind having a handle by which the samev may be grasped, said handle being also adapted to clamp and lock the grips'against ari object.
A Rfurther object isvto furnish in a device of this nature, arest adapted to bear against thev object to ber moved" andy to steady the device with respect to said object.
With theforegoing and other objects in View', whichfwill appear in the following description, the invention resides in the novel combination and arrangement of parts and in the details of construction hereinafter described and claimed.
In the drawings, Fig. 1 is a plan view of my improved device, certain portions thereof being broken away to reveal otherwise con- Cea-led parts; Fig. 2 is a side Aelevation thereof and is shown in operative positionv as applied to a plate of glass; Fig. 3 is a perspective view in detail illustrating the pintle for pivotally connecting the levers and also showing the rest attached to said pintle; Fig. 4 is a fragmentary view of my improved device portraying an alternate form thereof.
Referring to the drawings, I have used the reference numeral 10 to indicate the levers which form the body of my improved tongs. These levers are pivotally con nected at or near the centers thereof by means of a rivet 11 (Fig. 4) or by means of yspreads and closes the iaws 17.
a. lpintle 12 (Fig. 3), which is secured in the other at the point of connection and are offset at either side thereof to `form jaws 17 and arms 18. The tips ofthe jaws are twisted at right angles as at 19 and are curved as shown in Fig. 1, similar openings 2O being formed .in said tips at the highest points in said curved portions. Opposed grips 21 are mounted on these Ajaw tips. 'Each grip includes a block 22 and a pad 23, preferably of rubber, onthe face thereof.
ture 24 to receive the bolt 25 loosely fitted in the opening 2O of a jaw 17 and an enlargement 26 .of said aperture receives a nut 27 on said bolt. LEach arm 18 has a threaded link28 pivotally attached thereto by means cfa bolt or rivet 29. These .links are oppositely threaded, viz, one is formed with righthand threads and the other with left hand threads. Said linksare fitted into opposite ends of a handle 30 having a longiktudinally threaded bore 31 adapted to receive them. The turning of this handle 3() `It will therefore be seen that the grips 21 may be clamped and locked against opposite sides of objects of various dimensions by manipulation of the handle SO'and further that said :handle provides a grasp for the user in carrying the tongs and object secured therein.
In use my tongs are applied to the margin of a glass plate in the manner shown in Fig. 2. To prevent the levers 17 from coming into contact with the glass at the point of connection between said levers, I supply a cushioned rest 32, which bears against the edge of the glass. In one form, this rest comprises a holder 33 having ears 34 connected by a bolt 35 to the projection 16 on the pintle 14, said holder containing a cushion 33aL of soft wood, rubber, cork or other suitable material, having an elongated recess 33b to receive the margin of a plate of glass. This recess is V shaped in cross section to accommodate glass of different thickness. Said rest performs an additional function in dividing` with the grips 21 any strain upon the tongs in directions out ot' the plane occupied by the plate ot glass to which said tongs are applied, thus avoiding breakage which might otherwise occur at the hands ot a careless user. In my modified form, the rest 32 comprises a cushioned guard ot leather or other suitable material placed around the levers 17 at the junction thereof. f
My device is used in pairs, one being secured upon one margin of the object to be carried and the other upon the opposite margin thereof. The handles 30, being tightenec, are conveniently grasped by the users, each having a tree hand tor steadying the object.
I-Iaving described my invention, what I claim as new and desire 'to protect by Letters Patent is:
l. In a device of the class described, a pair of levers pivotally connected between the ends thereof, the junction between said levers forming a rest adapted to bear against an object grasped by the device, the adjacent ends of the levers forming opposed arms on one side of the rest and opposed jaws on the other side of said rest, a revoluble grip carried by said arms and providing a combination handle and arm actuating device for spreading, retracting and locking the arms with respect to each other to thereby close, open and secure said jaws.
2. In a device ot the class described a pair otlevers pivotally connected between the ends thereof, said ends of said levers 4jofming opposed arms and, jaws, grips mounted on the jaws, a combination handle and spreader mounted between said arms and a rest at the point of connection between said levers.
8. In a device of the class described, a`
form opposed arms and jaws, oppositelyv threaded links attached to said arms, a handle having a longitudinally threaded bore receiving said threaded links, said handle being` adapted, when turned, to spread the arms and close the jaws or vice versa and a' rest at the point of connection between said levers.
t. In a device of the class described, a pair of levers pivotally connected near the centers thereof, the ends oi: said levers being offset trom 'the point ot connection to torni opposed arms and jaws, grips mounted on the aws, oppositcly threaded links attached to said arms, a handle having a longitudinally threaded bore receiving said links, said handle being adapted, when turned, to spread the arms and close'the jaws or vice versa anda selrP adjustable rest at the point et connection between said levers.
5. In a device ot the class described, a pair ot levers, a pintle connecting said levers near the centers thereof, the ends of levers being offset from the point of connection to form opposed arms and jaws, companion grips mounted on the jaws, oppositely threaded links attached to said arms and a handle having a longitudinally threaded bore receiving said 'threaded links, said handle being adapted, whenturned, to
kopen and close vthe jaws, a' rest pivotally mounted on said pintle and a cushion therein Ytermed with an c-rongated recess, V shaped section and adapted to receive the .O'in oit a plate oi glass or other object to e device is applied.
In testimony whereof, I have signed my name to this specification.
