On March 10, 1967 the jury returned verdicts of guilty on both counts of an indictment charging the appellant with selling heroin hydrochloride in violation of 21 U.S.C. § 173 and § 174. On April 18, 1967 he was sentenced to six years imprisonment on each count, the sentences to run concurrently. On this appeal, appellant claims that the trial court committed reversible error when it denied his application, made on the threshold of the trial, for a continuance for the purpose of retaining new counsel and when it directed that the trial should go forward with counsel of record without expressly advising appellant of his right to proceed pro se.

At the time, the accused represented to the trial court that his reason for changing lawyers was that he had never had an opportunity to confer with his present counsel about the case. The attorney, however, stated that, contrary to the defendant's assertions, he had thoroughly discussed the case with the accused on several occasions and as an officer of the court, he was prepared to represent Clausell at the trial, but that the accused had requested him to stall for time, which he refused to do. Under these circumstances the trial court was justified in concluding that the appellant was trying to engage in "endless delays and maneuvers that * * * only [had] a dilatory purpose," United States v. Abbamonte, 348 F.2d 700, 703 (2 Cir. 1965), and did not commit error by denying the continuance. Compare United States v. Bentvena, 319 F.2d 916, 936 (2 Cir.), cert. denied, 375 U.S. 940, 84 S. Ct. 345, 11 L. Ed. 2d 271 (1963); United States v. Terranova, 309 F.2d 365, 366 (2 Cir. 1962); United States v. Arlen, 252 F.2d 491, 494 (2 Cir. 1958).

Concerning the appellant's claim that he was not advised of his right to proceed pro se, this court has held that "[r]egardless of whether he [the defendant] has been notified of his right to defend himself, the criminal defendant must make an unequivocal request to act as his own lawyer in order to invoke the right." United States ex rel. Maldonado v. Denno, 348 F.2d 12, 15 (2 Cir. 1965). As we noted in Abbamonte, supra, the "preferable procedure" would be to inquire whether the defendant wished to continue with his retained counsel or alternatively proceed pro se, 348 F.2d at 704, but where, as in both Abbamonte and the present case, the defendant gives no indication that he wishes to defend himself and the trial judge can conclude that the accused's only dissatisfaction with his attorney is the latter's refusal to stall the trial, we will not afford the "convicted criminals * * a ready tool with which to upset adverse verdicts after trials at which they had been represented by counsel."1 United States ex rel. Maldonado v. Denno, supra at 16.

The appellant also claims that the trial judge erred when he directed that the appellant be tried by a jury after his counsel had informed the court that the accused had said "that he doesn't want a jury trial." Immediately following the attorney's statement the trial judge asked the accused whether or not he wanted a trial by jury and the accused refused to answer. In any event there is no merit to the appellant's contention. An accused has no absolute or exclusive right to elect a trial by the court alone without a jury. See Singer v. United States, 380 U.S. 24, 85 S. Ct. 783, 13 L. Ed. 2d 630 (1965); Janko v. United States, 281 F.2d 156, 170 (8 Cir. 1960); Rule 23(a) of the Fed.Rules of Crim. Procedure.

We have considered the additional arguments raised by appellant pro se in his petition to amend brief, dated December 22, 1967, and find them devoid of merit.

The judgments of conviction are affirmed.
