SPECIFICATION forming part of Letters Patent No. 689,766, dated December -24, 190i.
Application tied May s, 190i. serial No. tasse. (No model.)
1o and described in my prior patent, No. 463,469,
dated November 17, 1891, and has for its object to provide a drill-frame having certain novel features of construction whereby the structure as a whole will be light and simple r ,and possess .great strength.
In order to enable my invention to be clearly understood, I have illustrated the same in the accompanying drawings, in which- Figure 1 is a perspective view of the drill-f 2o frame.
Fig. 2 is a transverse section thereof, taken through one of the end castings. Fig. 3 is a detail View of one of the sidev bars, and Fig. 4 is a like View of an end casting. n
Referring now to the drawings, l indicates 2 5 the side bars of the drill frame or post,which are formed of plates of metal provided on their inner sides with flat bearing-faces and with central longitudinal grooves 2, eXtendl ing throughout the length of the bars. Said 3o bars are thickened or conveXed longitudinally, as indicated at 3, so that they shall not be weakened by the provision of the grooves 2. On the contrary, said bars constructed as described are much stronger than ordinary flat metal bars would be on the principle well understood by those familiar with'metal constructions. has a flange extension 4, which is provided with a series of recesses 5 toreceive the 4o trunnions of the gear-box, as usual. At their upper ends the side bars are united to an end casting, which consists of a central cylindrical` sleeve 6, provided on opposite sides with thick integral webs 7 ,terminating in rela- 4 5 tively wide iianges 8, which have their outer sides flat to bear against the faces of the side bars and provided with tongues 9, adapted to be received and t closely in the grooves 2 of the side bars. The end casing is secured in 5o position by means of cap-screws 10 passing At one side each of the lbai-s1 through openings inthe side bars and engaging in suitable screw-threaded openings in said casting. Upon one sidelof the sleeve 6, which forms a boxfor an extension-pipe 11, is cast a boss or nipple l2, having a threaded opening for aset-screw 13, by means of which the extension-pipell may be locked in any desired adjusted position. At their lower ends the side bars are connected to an end casting 14, similar in all material respects to the one described and differing therefrom only in the provision of a female thread in the central sleeve or box, which receives a jackscrew 15, having .a handle or lever 16, as usual. Y
By the construction of side bars above described I ain enabled to dispense with separate trunnion-support-ing plates, such as shown in my patent named, and also with the side iianges on the end castings for embracing the edges of the side bars, as the tongue-andgroove connection shown answers all the purposes of thesev anges-that is to say, the engagement of the tongues 9 in the grooves 2 operates to hold the end'castings in firm fixed relation to the side bars.
Having thus fully described my invention, what I claim as new is- 1. A post-drill framehaving side bars each of which is in the form of a metal bar flat on its inner side and provided on said inner side with a central longitudinal groove and a corresponding thickened portion opposite said groove.
2. A post-drill frame having side bars,each of which is in the form of a metal bar flat on its inner side and provided with a central longitudinal groove, and end castings secured between said bars at opposite ends thereof and having on Opposite sides tongues seated in said grooves. Y p y Y 3. A post-drill frame having side bars,eacl1 of which is in the form of a'frnetal bar at on its inner side and provided with a central longitudinal groove and an integral anged eX- tension 4'provided with recesses 5.
4. A post-drill frame having side bars,'each of which is provided with a iiat bearing-surface and with a central `longitudinal groove, and end castings secured between said bars IOO site ends thereof and having on opposite sides x tongues seated in said grooves.
In testimony whereof I have hereunto set my hand in presence of two subscribing witmesses.
