sfclaims. (Cl. s1-say breaker to clear the way of such obstructions, to prevent clogging of open-end pipes by large boulders and to protect the relatively weak ends of such piles from damage,
It is also an object of the invention to adopt this tip,
to closed end pipe piles and to mandrel driven shells similar to` the tip described in our patent application Serial No.` 554,245.v
Open-end pipe piles and H-beam bearing piles are generally used only where the intention is to drivepilesV to rock. The material in the open-end pipe piles is blown out after driving and the pile is,` inspected.l If the openend pipe pile is not on rock it can be driven down further unlessv it is damaged. The. difliculty in many cases, especially with piles 80 feet long` or longer, is` that on the way down to bedrock, layers of hardpan and boulders are generally encountered, especially inthe. region directly overlying rock so. that the piles become damaged because of such obstructions. Our tips or points have been designed to overcome these diiculties'. Open-end pipe piles are driven at the present time without any tip or point;v
in almost all instances.` Occasionally, a steel ring of some harder steel than the pipe itself is welded onto. theV pipe. Similar condition prevail with H-beam piles. This results in damaged piles, bent or doglegged. Such piles must be rejected resulting in great loss. In theycase of open-end pipe piles, large boulders wedge4 themselves intol the` pipe4 which are exceedingly difcult and ofttimes irn-` possible to dislodge or remove. In instances where attempts havek been made to remove such boulders, a great deal of timev is lost thus greatly increasing the cost. Under such conditions the steel ring weldedy to the end of the pipe is of no assistance whatever.
We have provided cross-blades on our tips or points so that'large boulders cannot enter the pipe while loose material, such as sand, gravel, clay and silt are permitted to pass upward through the pipe. The blades will disperse large boulders, will cut through dense materials and will prevent the pile from being hung up before reaching acceptable bearing material or bedroek. Piles heretofore used are hung up rather often where the resistance of the material, especially hardpan or decomposed rock is so large that no amount of Ydriving can` overcome it. Our tips will attach themselves to bedrock and assure proper seating ofthe pile and will also pro` tect pipe pile from collapsing or Crumpling.
With the Hbeam bearing pile, our tip will protect no inspection after driving islpossible.

' tains is blown out by Ycompressed airfas` heretofore stated, and the pipe is washed witha stream ofWater. The material around the tripl of the pile isalso washed'A oY leaving a base for concrete larger than Ithe diameter of the pile. This is a distinct advantage since it gives the pile a largerand rmer llold-n on the underlying rock and greater security against lateralmovement, In the case of shorter piles, where only occasional dilnculty is met, the tip may be attached to a smaller pipe fitting into the pipe pile andl used vas a ram oriispudv inside of the largerv pipe tov clear it of.,` wedged-in,v boulders or other materia1.
Our tips o r pointssave a great deal in cost since the cost of but one ruined pile diiven without protection of our point is many times the cost of a tip or Ipoint. It is,
therefore, evident that our tips or points not onlyrr savey a great deal in cost but also intime since a ruined pile must be corrected. .i v

Referring to Figs. l to 5 of the drawings, nurrle-ralA 20.. represents a four bladed pile driving tip or pointwfo); eren-end pire piles, mede preferably 0f east steel but may be made of other material, such als east iron, o r other metals or alloyed metals. 'l `h e upper end has a collar` 21, the inside wall 22, of which isfslightly taperedV out; wardly at its inner circumference. The circumferential shoulder 23 is adapted to receive the end 2 4 of an openend pipe pile 30. Below collarrZl there are four blades or cutters 25A, each blade being in the form o`f aboutV half a spear pointing downwardly.Y The distal blade end,` 26 is thicker than the upper blade end 21 at the collar 2&1, tapering gradually fromthe bottom or lisxtalend` to the upper blade venel 27. .The bladesv 25 are preferably of uniform size and the extreme edges28 of each blade extend outwardly beven@ the enfer .eireumferenee ,et the cellar ,2 1, Per e, feu inch pire, rile., we prefer to. here. a thickness. of about 2 inches et.' the bettem'z et4 the blade er et. the peint end @beet Iitlelt. in, thielsaess it the upper Dertien ef the blade.. 2.5 Where. it @este the, eelle'ZL YThereeler 211e pfeereblr ebeut oiierhelf. inch thick above the shoulder V23 and about l inch thick at its lower portion. Of course, the thickness of the tapering blades 25 and the collar 21 will vary depending upon the diameter of open-end pipe to be driven and the character of the metal used. The blade end 26 may be blunt as shown, or may be' pointed, as shown in Fig. 5. The outer edges `29 may be square as shown in Fig. 3 or rounded, as shown'in Fig. 4, or may be pointed, as shown in Fig. 5. The blades 25 also taper outwardly towards the vertical medial line, that is the blades 25 are somewhat thicker in the center than at the outer edges, as best shown in Figs. 2 and 3.
The collar 21 and blades 25 are preferably cast integrally. It is preferable to weld the pipe 30 to the tip 20 so that the tip or point 20 becomes an integral part of the pile. The tip or point 20 can also be readily adapted for closed end piles by casting or welding a horizontal steel plate 36 or 38 upon shoulder 23.
The tapered inner wall 22 permits the end of pipe 30 to slide into the top opening until the end 24 of pipe 30 is properly seated. It is evident that when the tip or point 20 is fastened or welded to smaller diameter pipe than the pipe to be driven, and the pipe to which the tip is fastened is of extra heavy wall thickness, such combination may then be readily used as a ram or spud, inside of larger pipe driven as a pile and can then be extracted.
Referring to Figs. 6, 7 and 8, these driving tips or points are similar in all respects to the four bladed pile driving tip of Figs. 1 to 5, except that such tips are for two, three and five blades, respectively. Such tips or points are used in the same manner as the tip shown and described in Figs. l to 5.
Referring to Fig. 9, this tip 31 is also very much like the tip of Figs. l to 5, except that the collar 32 has an outer circumferential shoulder 33 with the upper collar portion 35 tapered inwardly to fit inside the pipe pile 34 so that the pipe 34 can slide down the tapered collar portion 35 to the shoulder 33 and be somewhat wedged therein because of the taper. The shoulder 33 is wide enough to accommodate the thickness of pipe 34. It is then preferable to weld the collar 32 and the pipe 34 together to insure that the tip will not become dislodged from the pipe when it is driven into the ground.
The tip 31 shown in Fig. 9 may be used for both openend pipe pile or closed end piles since tip 31 has an integrally formed plate 36 closingthe vertical opening of the collar 32. When used for open-end pipe piles, plate 36 is omitted in casting.
Fig. 9a shows a modification of Fig. 9 in that an inner shoulder 37 is employed to receive a steel plate 38. The wall 39 is somewhat thickened below the plate 38 creating the shoulder 37. The plate 38 may be inserted when desired for use with a closed end pile and may be welded to the tip as well as to the end of the pipe pile. It is possible to use the tips of Figs. 9 and 9a for both open-end pipe pile and closed end piles.
Referring to Fig. 10, numeral 40 represents a four bladed pile driving tip for an H-beam bearing pile 44. This tip is in most respects like the tip of Fig. 1 and the same description would apply, except that-the collar 41 is substantially square. This inside wall 42 is also slightly tapered outwardly. The blades 45 extend upwardly within the collar 41 to the shoulder 43 so that the lower end of the H-beam pile rests upon the shoulder 43 and the top edge 50 of the blades 45. In Fig.- ll, the blades 45 are erosswise and in the modification, Fig. 12, the blades are positioned diagonally to the frame or collar 41. The tapered inner wall 42 permits the lower end of the H-beam pile to slide into the top opening until it is properly seated. It is preferable to weld the tip 40 to the end of the H-beam pile so that the tip 40 becomes an integral part of the pile. Of course, it is evident that two, three and live or more blades can also be used with the substantially square collar 41 in a manner similar to Figs. 6, 7 and 8, except for the square collar. The
4 blades 45 may also have the rounded edges of Fig. 4 or the pointed edges of Fig. 5.
It is also obvious that the cross blades need not necessarily be of the same width.
It should be noted that in all the forms shown the tip will disperse large boulders and permit looser material to pass through and upward (except for the closed forms when plates like 36, 38 are used); will clear the way of obstructions for the pile; will cut through dense material and prevent hung up piles; the cross members will stop large boulders from entering pipe and thus prevent clogging of pipe; will protect pipe or H-beam from collapsing or crumpling; will attach itself to bedrock and assure proper seating; will result in large savings and when material in pile is cleaned out a broader base is assured for concrete around the tip which can bc adapted both to open-end pipe piles or to shells of various kinds.
The driving points for the open-end pipe pile and the H-beam bearing pile can be made to accommodate the different standard sizes of pipe and H-beams now being used, and it is evident that the sizes and thicknesses of the points will vary with the size of the pipe and H-beams used and the character of the metal used for the points.
It is obvious that various changes and modifications may be made in the details of construction and arrangements of parts' without departing from the general spirit of the invention.
